  • Problem installing Ubuntu 10.04 64 bit side by side with Vista by using a bootable USB drive. What n

    - by Adam Siddhi
    What happened I decided to install Ubuntu 10.04 64 bit side by side with Vista Home Premium (I guess on another partition) with a USB stick. I found instructions on how to do this here: https://help.ubuntu.com/community/Installation/FromUSBStick To create the bootable USB drive I had to download a program called Unetbootin. That process was simple enough. All I had to do was just choose the disk image option, select the ubuntu-10.04-desktop-amd64.iso image, make sure it recognizes my USB drive and then press OK. It takes only like a few minutes to create a working bootable USB drive. Then I have to restart my computer, enter the BIOS, select my USB drive as the first boot drive, save options and continue with booting up. After this Ubuntu actually loads up. I think this is known as the Live version of Ubuntu so you can try it out before fully installing it. Any ways, on the Ubuntu 10.04 desktop I saw an installer. I click it and begin the installation process. Just so you know, I tried installing it 2 times. I will explain what happened each time: The first time I tried installing Ubuntu 10.04 I got stuck at step 4 of 7. I remember selecting the last option in the window which was Specify Partitions Manually (Advanced) I made my partition for Ubuntu like 52 gigs. I clicked forward and a little pop up window appeared saying Please Wait. So the installation process stalled on this window so I closed out of it and quit the installation process. So at this point I was worried because I had already selected the partition size and assumed it started making it. Since it stalled I had to quit out though. Anyways, once again I reached step 4 of 7 a decided to select the first option which is Install them side by side choosing between them each startup. I figured this was the safe way to go. I did that and the pop up window saying Please Wait popped up again but lasted only like 10 seconds. Then I got to I guess step 6 where it asks you to enter your desired name and password. Did that and clicked forward. The Ubuntu 10.04 installation load screen appeared and the loading bar at the bottom started filling up. So I got to 83% and stalled during the Importing other profile information (I think it was called this. I had the option to do this during I think step 6) process. So at this point I decided to get stop the installation process. I was getting very nervous. I tried to restart the computer but all that happened was that Ubuntu restarted. I finally got the computer to restart. I was pretty sure I had screwed something up big time by this point. As my computer was restarting I entered BIOS again and switched back to it booting from my main hard drive containing Vista. Saved it and continued the boot process. My worst fears were confirmed as Vista would not boot up. I mean I saw the little Microsoft Windows choppy animated green loading bar at the bottom of the screen and then boom! It decided to restart. When it restarted I had the option to run a memory test check to see if there was anything that needed to be repaired. That took like 20 minutes and at the end I saw that I did indeed have to repair something. I had to go through 2 repair processes. After each I had to restart the computer. The 2nd time it went through the repair process it said that it could not fully repair the damage. I was scared and restarted but Vista did load up. I got to my desktop and saw a message saying something like Repairs have been made, Please restart for changes to take effect I noticed that some Notification icons were missing and I could not hear volume in a video. Things were a bit funky. So I did restart and here I am. Now what?! So since I got back into Vista and thankfully have a working Internet connection I am trying to find answers to my problem (that is why I am writing this post). I am scared that I have partioned my hard drive 2 times after researching Installing Ubuntu 10.04 and seeing this post http://techie-buzz.com/foss/ubuntu-10-04-lts-installation-guide.html The author shows screen shots of installing Ubuntu 10.04. He shows the image of step 4 of 7 with a caption at the bottom. I will recreate it below: Select a partitioning option. Unless you want to format all the hard drive and install Ubuntu afresh, select the last option and proceed. Questions If I have indeed partitioned my HD 2 times (which I am sure it is), how do I get to a point where I can see all my bad, unfinished Ubuntu partitions and get rid of them? How do I clean this big mess up? & How can I ensure that this mess will not happen next time I try installing Ubuntu 10.04? Thank you Adam

  • NFS issue brings down entire vSphere ESX estate

    - by growse
    I experienced an odd issue this morning where an NFS issue appeared to have taken down the majority of my VMs hosted on a small vSphere 5.0 estate. The infrastructure itself is 4x IBM HS21 blades running around 20 VMs. The storage is provided by a single HP X1600 array with attached D2700 chassis running Solaris 11. There's a couple of storage pools on this which are exposed over NFS for the storage of the VM files, and some iSCSI LUNs for things like MSCS shared disks. Normally, this is pretty stable, but I appreciate the lack of resiliancy in having a single X1600 doing all the storage. This morning, in the logs of each ESX host, at around 0521 GMT I saw a lot of entries like this: 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4cf9a8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4dc9e8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4d3fa8 3 2011-11-30T05:21:54.161Z cpu2:2050)NFSLock: 608: Stop accessing fd 0x41000a4de0a8 3 [....] 2011-11-30T06:16:07.042Z cpu0:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:17:01.459Z cpu2:4011)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:25:17.887Z cpu3:2051)NFSLock: 608: Stop accessing fd 0x41000a4c2b28 3 2011-11-30T06:27:16.063Z cpu3:4011)NFSLock: 568: Start accessing fd 0x41000a4d8928 again 2011-11-30T06:35:30.827Z cpu1:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /tank/ISO, mounted as 5acdbb3e-410e56e3-0000-000000000000 ("ISO (1)") 2011-11-30T06:36:37.953Z cpu6:2054)NFS: 292: Restored connection to the server 10.13.111.197 mount point /tank/ISO, mounted as 5acdbb3e-410e56e3-0000-000000000000 ("ISO (1)") 2011-11-30T06:40:08.242Z cpu6:2054)NFSLock: 608: Stop accessing fd 0x41000a4c3e68 3 2011-11-30T06:40:34.647Z cpu3:2051)NFSLock: 568: Start accessing fd 0x41000a4d8928 again 2011-11-30T06:44:42.663Z cpu1:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:44:53.973Z cpu0:4011)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:51:28.296Z cpu5:2058)NFSLock: 608: Stop accessing fd 0x41000ae3c528 3 2011-11-30T06:51:44.024Z cpu4:2052)NFSLock: 568: Start accessing fd 0x41000ae3b8e8 again 2011-11-30T06:56:30.758Z cpu4:2058)WARNING: NFS: 283: Lost connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T06:56:53.389Z cpu7:2055)NFS: 292: Restored connection to the server 10.13.111.197 mount point /sastank/VMStorage, mounted as f0342e1c-19be66b5-0000-000000000000 ("SAStank") 2011-11-30T07:01:50.350Z cpu6:2054)ScsiDeviceIO: 2316: Cmd(0x41240072bc80) 0x12, CmdSN 0x9803 to dev "naa.600508e000000000505c16815a36c50d" failed H:0x0 D:0x2 P:0x0 Valid sense data: 0x5 0x24 0x0. 2011-11-30T07:03:48.449Z cpu3:2051)NFSLock: 608: Stop accessing fd 0x41000ae46b68 3 2011-11-30T07:03:57.318Z cpu4:4009)NFSLock: 568: Start accessing fd 0x41000ae48228 again (I've put a complete dump from one of the hosts on pastebin: http://pastebin.com/Vn60wgTt) When I got in the office at 9am, I saw various failures and alarms and troubleshooted the issue. It turned out that pretty much all of the VMs were inaccessible, and that the ESX hosts either were describing each VM as 'powered off', 'powered on', or 'unavailable'. The VMs described as 'powered on' where not in any way reachable or responding to pings, so this may be lies. There's absolutely no indication on the X1600 that anything was awry, and nothing on the switches to indicate any loss of connectivity. I only managed to resolve the issue by rebooting the ESX hosts in turn. I have a number of questions: What the hell happened? If this was a temporary NFS failure, why did it put the ESX hosts into a state from which a reboot was the only recovery? In the future, when the NFS server goes a little off-piste, what would be the best approach to add some resilience? I've been looking at budgeting for next year and potentially have budget to purchase another X1600/D2700/disks, would an identical mirrored disk setup help to mitigate these sorts of failures automatically? Edit (Added requested details) To expand with some details as requested: The X1600 has 12x 1TB disks lumped together in mirrored pairs as tank, and the D2700 (connected with a mini SAS cable) has 12x 300GB 10k SAS disks lumped together in mirrored pairs as sastank zpool status pool: rpool state: ONLINE scan: none requested config: NAME STATE READ WRITE CKSUM rpool ONLINE 0 0 0 c7t0d0s0 ONLINE 0 0 0 errors: No known data errors pool: sastank state: ONLINE scan: scrub repaired 0 in 74h21m with 0 errors on Wed Nov 30 02:51:58 2011 config: NAME STATE READ WRITE CKSUM sastank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c7t14d0 ONLINE 0 0 0 c7t15d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c7t16d0 ONLINE 0 0 0 c7t17d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c7t18d0 ONLINE 0 0 0 c7t19d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c7t20d0 ONLINE 0 0 0 c7t21d0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c7t22d0 ONLINE 0 0 0 c7t23d0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c7t24d0 ONLINE 0 0 0 c7t25d0 ONLINE 0 0 0 errors: No known data errors pool: tank state: ONLINE scan: scrub repaired 0 in 17h28m with 0 errors on Mon Nov 28 17:58:19 2011 config: NAME STATE READ WRITE CKSUM tank ONLINE 0 0 0 mirror-0 ONLINE 0 0 0 c7t1d0 ONLINE 0 0 0 c7t2d0 ONLINE 0 0 0 mirror-1 ONLINE 0 0 0 c7t3d0 ONLINE 0 0 0 c7t4d0 ONLINE 0 0 0 mirror-2 ONLINE 0 0 0 c7t5d0 ONLINE 0 0 0 c7t6d0 ONLINE 0 0 0 mirror-3 ONLINE 0 0 0 c7t8d0 ONLINE 0 0 0 c7t9d0 ONLINE 0 0 0 mirror-4 ONLINE 0 0 0 c7t10d0 ONLINE 0 0 0 c7t11d0 ONLINE 0 0 0 mirror-5 ONLINE 0 0 0 c7t12d0 ONLINE 0 0 0 c7t13d0 ONLINE 0 0 0 errors: No known data errors The filesystem exposed over NFS for the primary datastore is sastank/VMStorage zfs list NAME USED AVAIL REFER MOUNTPOINT rpool 45.1G 13.4G 92.5K /rpool rpool/ROOT 2.28G 13.4G 31K legacy rpool/ROOT/solaris 2.28G 13.4G 2.19G / rpool/dump 15.0G 13.4G 15.0G - rpool/export 11.9G 13.4G 32K /export rpool/export/home 11.9G 13.4G 32K /export/home rpool/export/home/andrew 11.9G 13.4G 11.9G /export/home/andrew rpool/swap 15.9G 29.2G 123M - sastank 1.08T 536G 33K /sastank sastank/VMStorage 1.01T 536G 1.01T /sastank/VMStorage sastank/comstar 71.7G 536G 31K /sastank/comstar sastank/comstar/sql_tempdb 6.31G 536G 6.31G - sastank/comstar/sql_tx_data 65.4G 536G 65.4G - tank 4.79T 578G 42K /tank tank/FTP 269G 578G 269G /tank/FTP tank/ISO 28.8G 578G 25.9G /tank/ISO tank/backupstage 2.64T 578G 2.49T /tank/backupstage tank/cifs 301G 578G 297G /tank/cifs tank/comstar 1.54T 578G 31K /tank/comstar tank/comstar/msdtc 1.07G 579G 32.8M - tank/comstar/quorum 577M 578G 47.9M - tank/comstar/sqldata 1.54T 886G 304G - tank/comstar/vsphere_lun 2.09G 580G 22.2M - tank/mcs-asset-repository 7.01M 578G 6.99M /tank/mcs-asset-repository tank/mscs-quorum 55K 578G 36K /tank/mscs-quorum tank/sccm 16.1G 578G 12.8G /tank/sccm As for the networking, all connections between the X1600, the Blades and the switch are either LACP or Etherchannel bonded 2x 1Gbit links.

  • Adobe Coldfusion Railo OpenBD Apache Tomcat Multiple Sites

    - by chris hough
    Here's what I am trying to do, unless I am crazy: I am trying to use Tomcat with the multiple workers, so far I got OpenBD working, but having trouble with Railo, and will be tackling Adobe after. each engine deployed as a war separated by different workers I wanted to keep both the sites and engines inside my sites directory I have to remap the symlink for the WEB-INF when I switch engines = have not found a way around this my thought is to have everything separated into modules and I want to be able to execute both cfm and php code in a single site.  Ideally, it would be amazing if there would be a way to not have to remap the symlink as well. thoughts? can this be done? I am trying to mimic how this would be setup on a live server, not using eclipse for example. here is what I am working with so far: my apache workers.properties worker.list=openbd, openbdadmin, railo, railoadmin  worker.openbd.type=ajp13  worker.openbd.host=local.mydev.openbd  worker.openbd.port=8009 worker.openbdadmin.type=ajp13  worker.openbdadmin.host=local.admin.openbd worker.openbdadmin.port=8009   worker.railo.type=ajp13  worker.railo.host=local.mydev.railo  worker.railo.port=8009 worker.railoadmin.type=ajp13  worker.railoadmin.host=local.admin.railo worker.railoadmin.port=8009   my tomcat servers.xml < Host name="local.admin.openbd" appBase="/Users/[myusername]/Websites/coldfusion.engines"  unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false"        < Context path="" docBase="openbd/" reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host        < Host name="local.admin.railo"   appBase="/Users/[my username]/Websites/coldfusion.engines" unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false"        < Context path="" docBase="railo/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host < Host name="local.mydev.openbd"   appBase="/Users/[my username]/Websites/coldfusion.engines" unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false" < Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true"< /Context < /Host < Host name="local.mydev.railo"   appBase="/Users/[my username]/Websites/coldfusion.engines"  unpackWARs="false" autoDeploy="true" xmlValidation="true" xmlNamespaceAware="false" < Context path="" docBase="/Users/[my username]/Websites/example.mydev/wwwroot/"  reloadable="true" privileged="true" antiResourceLocking="false" anitJARLocking="false" allowLinking="true" < /Host my apache vhosts ServerName local.admin.openbd DocumentRoot /Users/[my username]/Websites/coldfusion.engines/openBD/ #Mount OpenBD and tell it to only server cfml files JkMount /*.cfm openbdadmin ErrorLog "/Users/[my username]/Websites/apache.logs/local_openbdadmin_error.log" ServerName local.admin.railo DocumentRoot /Users/[my username]/Websites/coldfusion.engines/railo/ #Mount Railo and tell it to only server cfml files JkMount /*.cfm railoadmin ErrorLog "/Users/[my username]/Websites/apache.logs/local_railoadmin_error.log" ServerName local.mydev DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_error.log" ServerName local.mydev.openbd DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot #Mount OpenBD and tell it to only server cfml files JkMount /*.cfm openbd ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_openbd_error.log" ServerName local.mydev.railo DocumentRoot /Users/[my username]/Websites/example.mydev/wwwroot JkMount /*.cfm railo ErrorLog "/Users/[my username]/Websites/apache.logs/local_example_mydev_railo_error.log" my folder structure I am using websites/apache.logs/ websites/coldfusion.engines/ websites/coldfusion.engines/cfusion/ websites/coldfusion.engines/openBD/ websites/coldfusion.engines/railo/ websites/example.mydev/ websites/example.mydev/wwwroot/ websites/example.mydev/wwwroot/index.cfm   websites/example.mydev/wwwroot/index.htm   websites/example.mydev/wwwroot/index.php   error log output [Thu Aug 27 00:54:50.443 2009] [11279:2686719776] [info] init_jk::mod_jk.c (3183): mod_jk/1.2.28 initialized [Thu Aug 27 00:54:51.346 2009] [11280:2686719776] [info] init_jk::mod_jk.c (3183): mod_jk/1.2.28 initialized [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [info] jk_open_socket::jk_connect.c (594): connect to 127.0.0.1:8009 failed (errno=61) [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [info] ajp_connect_to_endpoint::jk_ajp_common.c (922): Failed opening socket to (127.0.0.1:8009) (errno=61) [Thu Aug 27 00:55:18.963 2009] [11284:2686719776] [error] ajp_send_request::jk_ajp_common.c (1507): (openbdadmin) connecting to backend failed.

    - by goofrider
    I have a nasty rootkit that not tools seem to be able to idenity. I know for sure it's a rootkit, but I can figure out which rootkit it is. Here's what I gathered so far: It creates multiple copies of itself in %HOME%\Local Settings\Temp with names like Q.EXE, IAJARZ.exe, etc., and install them as hidden services. These EXE have SysInternals identifiers in them so they're definitely rootkits. It hooked very deep in the system, including file read/write, security policies, registry read/write, and possibly WinSock/TCP/IP. When going to Sophos.com to download their software, the rootkit inject something called Microsoft Ajax Tootkit into the page, which injects code into the email submission form in order to redirect it. (EDIT: I might have panicked. Looks like Sophos does use an AJAZ email form, their form is just broken on Chrome so it looked like a mail form injection attack, the link is http://www.sophos.com/en-us/products/free-tools/virus-removal-tool/download.aspx ) Super-Antispyware found a lot of spyware cookies, in the name of .kaspersky.2o7.net, etc. (just chedk 2o7.net, looks like it's a legit ad company) I tried comparing DNS lookup from the infected systems and from system in other physical locations, no DNS redirections it seems. I used dd to copy the MBR and compared it with the MBR provided by ms-sys package, no differences so it's not infecting MBR. No antivirus or rootkit scanner be able to identify it. Most of them can't even find it. I tried scanning, in-situ (normal mode), in safe mode, and boot to linux live CD. Scanners used: Avast, Sophos anti rootkit, Kasersky TDSSKiller, GMER, RootkitRevealer, and many others. Kaspersky reported some unsigned system files that ought to be signed (e.g. tcpip.sys), and reported a number of MD5 mismatches. But otherwise couldn't identify anything based on signature. When running Sysinternal RootkitRevealer and Sophos AntiRootkit, CPU usage goes up to 100% and gets stucked. The Rootkit is blocking them. When trying running/installing HiJackThis, RootkitRevealer and some other scanners, it tells me system security policy prevent running/installing it. The list of malicious acitivities go on and on. here's a sample of logs from all my scans. In particular, aswSnx.SYS, apnenfno.sys and PROCMON20.SYS has a huge number of hooks. It's hard to tell if the rootkit replaced legit program files like aswSnx.SYS (from Avast) and PROCMON20.SYS (from Sysinternal Process Monitor). I can't find whether apnenfno.sys is from a legit program. Help to identify it is appreciated.

  • Trying to configure HWIC-3G-HSPA

    - by user1174838
    I'm trying to configure a couple of Cisco 1941 routes. The are both identical routers. Each as a HWIC-1T (Smart Serial interface) and a HWIC-3G-HSPA 3G interface. These routers are to be sent to remote sites. We have connectivity to one of the sites but if remote site A gors down we lose connectivity to remote site B. The HWIC-1T is the primary WAN interface using frame relay joining the two remote sites We want the HWIC-3G-HSPA to be usable for direct connectivity from head office to remote site B, and also the HWIC-3G-HSPA is do be used for comms between the remote sites when the frame relay is down (happens quite a bit). I initialy tried to do dynamic routing using EIGRP however in my lab setup of laptop - 1941 - 1941 - laptop, I was unable to get end to end connectivity. I later settled on static routing and have got end to end connectivity but only over frame relay, not the HWIC-3G-HSPA.

Manually pinging the IP assigned (by the telco) to ce0/1/0 does bring the interface up. Any ideas? Thanks

  • Windows 8, NVIDIA graphics recognition fails

    - by Roy Grubb
    I just installed Windows 8 Pro OEM 64-bit (clean install) and it won't properly recognize my graphics adapter. When I installed Win8, it automatically installed the BasicDisplay.sys driver dated 6/21/2006. 6.2.9200.16384 (win8_rtm.120725-1247). Hardware - Mobo:MSi G41M-P33 Combo CPU:Intel CoreDuo 6600 Graphics:NVIDIA GeForce 9400GT *OS* - Windows 8 Pro 64-bit OEM The graphics adapter worked fine in Windows XP. The PC is a generic box, bought locally and its mobo failed recently, so I replaced it with the G41M. Microsoft wouldn't let me re-activate Windows XP with a different mobo, so I installed Win8, which appears to work except as described next. Win8 only partially recognizes the graphics adapter and won't allow NVIDIA latest driver installer to see that it's an NVIDIA card. As a result, OpenGL doesn't work, and this is needed by the software I most use. Other than that the graphics look OK. When I say 'partially recognizes', I mean that via the Control Panel, I can see that the adapter is described as NVIDIA, but the driver remains stuck at Microsoft Basic Display Adapter no matter what I try, including "Update driver..." in adapter properties. Display Screen Resolution Advanced Settings Adapter shows: Adapter Type: Microsoft Basic Display Adapter Chip Type: NVIDIA DAC Type: NVIDIA Corporation Bios Information: G27 Board - p381n17 Don't know what this means ... no mention of 9400GT Total Available Graphics Memory: 256 MB Dedicated Video Memory: 0 MB In fact the adapter has 512MB on-board video memory. System Video Memory: 0 MB Shared System Memory: 256 MB And Control Panel Device Manager Display adapters just shows Microsoft Basic Display Adapter. No other graphics adapter, and no unknown device or yellow question mark. What I have tried so far: 1. Cleared CMOS and reset. Updated BIOS and all mobo drivers as follows: 1st I used Driver Reviver to see if any driver updates were required. It found some but I didn't use that to get the drivers. Then I switched to MSi's own mobo driver utility Live Update 5. This also showed the board needed to update several so I used it to fetch the new drivers. After that it showed that everything was up to date and I checked with Driver Reviver again, which also reported no drivers now needed updating. Rebooted. Went to the NVIDIA site to get the latest graphics adapter driver. Their auto-detect "Option 2: Automatically find drivers for my NVIDIA products" said "The NVIDIA Smart Scan was unable to evaluate your system hardware. Please use Option 1 to manually find drivers for your NVIDIA products." So I downloaded 310.70-desktop-win8-win7-winvista-64bit-international-whql.exe, which lists 9400 GT under supported products, but when I run it, it says: "NVIDIA Installer cannot continue This graphics driver could not find compatible graphics hardware." Connected the display to the on-board Intel graphics (G41 Intel Express), removed the NVIDIA card and rebooted, changed to internal graphics in CMOS. Again it installs the MS Basic Display Adapter, and can't properly run my s/w that needs OpenGL. It runs on other machines with Intel Express graphics (WinXP and 7) Shut down and pulled out the power cord. Held start button to discharge all capacitors. Removed and re-inserted NVIDIA adapter in PCI-E slot and made sure properly seated. Connected the monitor to the card, screwed plug to socket. Reconnected power cord. Started and checked in BIOS that Primary Graphics Adapter was set to PCI-E. Started Windows. Uninstalled MS Basic Display Adapter in Device Manager. Screen blanks briefly, reappears. No Graphics adapter entry was then visible in Device Manager. Restarted PC. MS Basic Display Adapter Visible again in Device Manager. Clicked in Device Manager View Show hidden devices. No other graphics adapter appears, no unknown devices. Rebooted. Tried Scan for Hardware changes. None detected. Tried right-click on MS Basic Display Adapter Properties Driver Update Driver... Search automatically. It replied that it had determined driver was up to date. I checked that there were no graphic driver-related entries in Programs and Features that I could delete (none). Searched for any other drivers with nvidia in their name and deleted them, just keeping the 306.97 installer exe file. Did a Windows Update. Ran GPU-Z which shows (main items): Microsoft Basic Display Adapter GPU G72 BIOS 5.72.22.76.88 Device ID 10DE - 01D5 DDR2 Bus Width 32 Bit Memory size 64MB Driver Version nvlddmkm 6.2.9200.16384 (ForceWare 0.00) / Win8 64 NVIDIA SLI Unknown in the drop-down at the foot, "Microsoft Basic Display Adapter" is the only option If I swap hard disks in that machine to one with a Ubuntu 10.4 installation (originally installed on the same PC), lspci shows "VGA compatible controller as NVIDIA Corporation Device 01d5 (rev a1) (prog-if 00 [VGA controller])" and "kernel driver in use: nvidia" I'm out of ideas for new things to try and would be really grateful of suggestions. Thanks!

  • DDNS Not Creating Journal (Dhcpd and Named)

    - by user130094
    * EDIT 1 * After monkeying with additional debug logging I see some log entries of interest. 27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: journal rollforward failed: no more 27-Jul-2012 23:45:26.537 general: error: zone example.lan/IN/internal: not loaded due to errors. ^^^ If I can remedy the above messages I think I'll be good to go ^^^ * EDIT 2 * Grasping at straws I touched a forward and a reverse zone journal file and restarted named. Boom! Works. Despite documentation stating the files are created automatically and what I have seen before... dunno why but that did the trick. Also re-checked perms on the dir the files live in. As certain as I was, they were correct with named having rw. CentOS 6 (final) dhcpd 4.1.1-P1 named BIND 9.8.2rc1-RedHat-9.8.2-0.10.rc1.el6 Basic DHCP and DNS functionality are in place on 192.168.111.2. Clients are assigned addresses as intended and can resolve local DNS names as well as Internet names. My problem is that named's zone journal files are not created. chroot: /var/named/chroot I tried placing the zone files in various directories (/var/named/data, /var/named, /var/named/dynamic - no matter which dir with named owning and wide open perms I now get nowhere). Along the way I, at one point, got a permission denied when named tried to create the journal. Resolved the issue by: chown --recursive named:named /var/named chmod --recursive 777 /var/named The journal was then created and here's where things fell apart. I attempted to tame permissions to something more sane and broke it. Once changed and having restarted named it threw an error indicating the journal was out of sync (or something to that affect)... didn't matter since this is a new setup so I deleted it and now it is not recreated. Now though I see no errors in /var/log/messages, my chrooted /var/log/named.log, or chrooted /var/log/named.debug. I increased the debug level with 'rndc trace' - no love. Increased trace to 10, still nothing. SELinux is disabled...

  • dual boot install--no GRUB

    - by Jim Syyap
    My computer recently had a hardware upgrade and now runs on Windows 7. I decided to install Ubuntu 11.04 as dual boot using the ISO I got from ubuntu.com downloaded onto my USB stick. Restarting with the USB stick, I was able to install Ubuntu 11.04 choosing the option: Install Ubuntu 11.04 side by side with Windows 7 (or something like that). No errors were encountered on installation. However on restarting, there was no GRUB; the system went straight into Windows 7.

  • CSC folder data access AND roaming profiles issues (Vista with Server 2003, then 2008)

    - by Alex Jones
    I'm a junior sysadmin for an IT contractor that helps small, local government agencies, like little towns and the like. One of our clients, a public library with ~ 50 staff users, was recently migrated from Server 2003 Standard to Server 2008 R2 Standard in a very short timeframe; our senior employee, the only network engineer, had suddenly put in his two weeks notice, so management pushed him to do this project before quitting. A bit hasty on management's part? Perhaps. Could we do anything about that? Nope. Do I have to fix this all by myself? Pretty much. The network is set up like this: a) 50ish staff workstations, all running Vista Business SP2. All staff use MS Outlook, which uses RPC-over-HTTPS ("Outlook Anywhere") for cached Exchange access to an offsite location. b) One new (virtualized) Server 2008 R2 Standard instance, running atop a Server 2008 R2 host via Hyper-V. The VM is the domain's DC, and also the site's one and only file server. Let's call that VM "NEWBOX". c) One old physical Server 2003 Standard server, running the same roles. Let's call it "OLDBOX". It's still on the network and accessible, but it's been demoted, and its shares have been disabled. No data has been deleted. c) Gigabit Ethernet everywhere. The organization's only has one domain, and it did not change during the migration. d) Most users were set up for a combo of redirected folders + offline files, but some older employees who had been with the organization a long time are still on roaming profiles. To sum up: the servers in question handle user accounts and files, nothing else (eg, no TS, no mail, no IIS, etc.) I have two major problems I'm hoping you can help me with: 1) Even though all domain users have had their redirected folders moved to the new server, and loggin in to their workstations and testing confirms that the Documents/Music/Whatever folders point to the new paths, it appears some users (not laptops or anything either!) had been working offline from OLDBOX for a long time, and nobody realized it. Here's the ugly implication: a bunch of their data now lives only in their CSC folders, because they can't access the share on OLDBOX and sync with it finally. How do I get this data out of those CSC folders, and onto NEWBOX? 2) What's the best way to migrate roaming profile users to non-roaming ones, without losing vital data like documents, any lingering PSTs, etc? Things I've thought about trying: For problem 1: a) Reenable the documents share on OLDBOX, force an Offline Files sync for ALL domain users, then copy OLDBOX's share's data to the equivalent share on NEWBOX. Reinitialize the Offline Files cache for every user. With this: How do I safely force a domain-wide Offline Files sync? Could I lose data by reenabling the share on OLDBOX and forcing the sync? Afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? b) Determine which users have unsynced changes to OLDBOX (again, how?), search each user's CSC folder domain-wide via workstation admin shares, and grab the unsynched data. Reinitialize the Offline Files cache for every user. With this: How can I detect which users have unsynched changes with a script? How can I search each user's CSC folder, when the ownership and permissions set for CSC folders are so restrictive? Again, afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? c) Manually visit each workstation, copy the contents of the CSC folder, and manually copy that data onto NEWBOX. Reinitialize the Offline Files cache for every user. With this: Again, how do I 'break into' the CSC folder and get to its data? As an experiment, I took one workstation's HD offsite, imaged it for safety, and then tried the following with one of our shop PCs, after attaching the drive: grant myself full control of the folder (failed), grant myself ownership of the folder (failed), run chkdsk on the whole drive to make sure nothing's messed up (all OK), try to take full control of the entire drive (failed), try to take ownership of the entire drive (failed) MS KB articles and Googling around suggests there's a utility called CSCCMD that's meant for this exact scenario...but it looks like it's available for XP, not Vista, no? Again, afterwards, how can I reinitialize the Offline Files cache for every user, without doing it manually, workstation by workstation? For problem 2: a) Figure out which users are on roaming profiles, and where their profiles 'live' on the server. Create new folders for them in the redirected folders repository, migrate existing data, and disable the roaming. With this: Finding out who's roaming isn't hard. But what's the best way to disable the roaming itself? In AD Users and Computers, or on each user's workstation? Doing it centrally on the server seems more efficient; that said, all of the KB research I've done turns up articles on how to go from local to roaming, not the other way around, so I don't have good documentation on this. In closing: we have good backups of NEWBOX and OLDBOX, but not of the workstations themselves, so anything drastic on the client side would need imaging and testing for safety. Thanks for reading along this far! Hopefully you can help me dig us out of this mess.

  • Mail Server on Google Apps, Hotmail Blocks

    - by detay
    My company provides private research tools (sites) for companies. Each site has its own domain name and users. These sites need to be able to send outbound mail for notifications such as password reminders. We started using Google Apps for this purpose, but lately we are having tremendous problems with mailing, especially to hotmail. I added the SPF record as required. Mxtoolbox says my domains are not in any blacklists. I was told to contact https://postmaster.live.com/snds/addnetwork.aspx and add my network. Given that I am using google's mail servers for sending mail, should I add their IP address for registering my domain? Or should I add my server's IP even though I am not hosting the mail server on it? Here's an example of a returned message; > Delivered-To: [email protected] Received: by 10.112.1.195 with SMTP > id 3csp62757lbo; > Mon, 10 Dec 2012 10:42:55 -0800 (PST) DKIM-Signature: v=1; a=rsa-sha256; c=relaxed/relaxed; > d=gmail.com; s=20120113; > h=mime-version:from:to:x-failed-recipients:subject:message-id:date > :content-type; > bh=x41JiCH75hsonh+5c/kzwIs7R8u4Hum2u396lkV3g2w=; > b=v+bBPvufqfVkNz2UrnhyyoGj1Cuwf6x/yMj0IXJgH27uJU7TqBOvbwnNHf33sQ7B9T > uGzxwryC2fmxBh72cGz1spwWK348nUp6KK73MXKnF8mpc3nPQ8Ke+EQpSPeJdq/7oZvd > scZTGpy//IiGEUDU5bJ7YPqYXQRycY5N6AF5iI4mWWwbS4opybp3IKpDDktu11p/YEEO > Fj9wnSCx3nLMXB/XZgSjjmnaluGhYNdh3JFtz83Vmr50qXTG/TuIXlkirP73GfGvIt2S > 7sy8/YdEbZR92mYe9wucditYr7MOuyjyYrZYCg+weXeTZiJX1PfBVieD+kD9MnCairnP > rQeQ== Received: by 10.14.215.197 with SMTP id e45mr52766237eep.0.1355164974784; > Mon, 10 Dec 2012 10:42:54 -0800 (PST) MIME-Version: 1.0 Return-Path: <> Received: by 10.14.215.197 with SMTP id > e45mr65950764eep.0; Mon, 10 Dec 2012 10:42:54 -0800 (PST) From: Mail > Delivery Subsystem <[email protected]> To: > [email protected] X-Failed-Recipients: ********@hotmail.fr > Subject: Delivery Status Notification (Failure) Message-ID: > <[email protected]> Date: Mon, 10 Dec 2012 > 18:42:54 +0000 Content-Type: text/plain; charset=ISO-8859-1 > > Delivery to the following recipient failed permanently: > > *********@hotmail.fr > > Technical details of permanent failure: Message rejected.

  • Should I go along with my choice of web hosting company or still search?

    - by Devner
    Hi all, I have been searching for a good website hosting company that can offer me all the services that I need for hosting my PHP & MySQL based website. Now this is a community based website and users will be able to upload pictures, etc. The hosting company that I have in mind, currently lets me do everything... let me use mail(), supports CRON jobs, etc. Of course they are charging about $6/month. Now the only problem with this company is that they have a limit of 50,000 files that can exist within the hosting account at any time. This kind of contradicts their frontpage ad of "UNLIMITED SPACE" on their website. Apart from this, I know of no other reason why I should not go with this hosting company. But my issue is that 50,000 file limit is what I cannot live with, once the users increase in significant number and the files they upload, exceed 50,000 in number. Now since this is a dynamic website and also includes sensitive issues like payments, etc. I am not sure if I should go ahead with this company as I am just starting out and then later switch over to a better hosting company which does not limit me with 50,000 files. If I need to switch over once I host with this company, I will need to take backups of all the files located in my account (jpg, zip, etc.), then upload them to the new host. I am not aware of any tools that can help me in this process. Can you please mention if you know any? I can go ahead with the other companies right now, but their cost is double/triple of the current price and they all sport less features than my current choice. If I pay more, then they are ready to accommodate my higher demands. Unfortunately, the company that I am willing to go with now, does NOT have any other higher/better plans that I can switch to. So that's the really really bad part. So my question(s): Since I am starting out with my website and since the scope of users initially is going to be less/small, should I go ahead with the current choice and then once the demand increases, switch over to a better provider? If yes, how can I transfer my database, especially the jpg files, etc. to the new provider? I don't even know the tools required to backup and restore to another host. (I don't like this idea but still..) Should I go ahead and pay more right now and go with better providers (without knowing if the website is going to do really that well) just for saving myself the trouble of having to take a backup of the 50,000 files and upload to a new host from an old host and just start paying double/triple the price without even knowing if I would receive back the returns as I expected? Backup and Restore in such a bulky numbers is something that I have never done before and hence I am stuck here trying to decide what to do. The price per month is also a considerable factor in my decision. All these web hosting companies say one common thing: It is customers responsibility to backup and restore data and they are not liable for any loss. So no matter what hosting company that I would like to go with, they ask me to take backup via FTP so that I can restore them whenever I want (& it seems to be safer to have the files locally with me). Some are providing tools for backup and some are not and I am not sure how much their backup tools can be trusted considering the disclaimers they have. I have never backed-up and restored 50,000 files from one web host to another, so please, all you experienced people out there, leave your comments and let me know your suggestions so that I can decide. I have spent 2 days fighting with myself trying to decide what to do and finally concluded that this is a double-edged sword and I can't arrive at a satisfactory final decision without involving others suggestions. I believe that someone must be out there who may have had such troublesome decision to make. So all your suggestions to help me make my decision are appreciated. Thank you all.

  • How to configure multiple WCF binding configurations for the same scheme

    - by Sandor Drieënhuizen
    I have a set of IIS7-hosted net.tcp WCF services that serve my ASP.NET MVC web application. The web application is accessed over the internet. WCF Services (IIS7) <--> ASP.NET MVC Application <--> Client Browser The services are username authenticated, the account that a client (of my web application) uses to logon ends up as the current principal on the host. I want one of the services to be authenticated differently, because it serves the view model for my logon view. When it's called, the client is obviously not logged on yet. I figure Windows authentication serves best or perhaps just certificate based security (which in fact I should use for the authenticated services as well) if the services are hosted on a machine that is not in the same domain as the web application. That's not the point here though. Using multiple TCP bindings is what's giving me trouble. I tried setting it up like this in my client configuration: <bindings> <netTcpBinding> <binding> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <client> <endpoint contract="Server.IService1" binding="netTcpBinding" address="net.tcp://localhost:8081/Service1.svc"/> <endpoint contract="Server.IService2" binding="netTcpBinding" address="net.tcp://localhost:8081/Service2.svc"/> </client> The server configuration is this: <bindings> <netTcpBinding> <binding portSharingEnabled="true"> <security mode="TransportWithMessageCredential"> <message clientCredentialType="UserName"/> </security> </binding> <binding name="public"> <security mode="Transport"> <message clientCredentialType="Windows"/> </security> </binding> </netTcpBinding> </bindings> <services> <service name="Service1"> <endpoint contract="Server.IService1, Library" binding="netTcpBinding" address=""/> </service> <service name="Service2"> <endpoint contract="Server.IService2, Library" binding="netTcpBinding" address=""/> </service> </services> <serviceHostingEnvironment> <serviceActivations> <add relativeAddress="Service1.svc" service="Server.Service1"/> <add relativeAddress="Service2.svc" service="Server.Service2"/> </serviceActivations> </serviceHostingEnvironment> The thing is that both bindings don't seem to want live together in my host. When I remove either of them, all's fine but together they produce the following exception on the client: The requested upgrade is not supported by 'net.tcp://localhost:8081/Service2.svc'. This could be due to mismatched bindings (for example security enabled on the client and not on the server). In the server trace log, I find the following exception: Protocol Type application/negotiate was sent to a service that does not support that type of upgrade. Am I looking into the right direction or is there a better way to solve this?

  • NLP with greatly contrained input and abilities

    - by Mike F
    Hat in hand here. I'm a seasoned developer and I would be grateful for a bit of help. I don't have time to read or digest long intricate discussions on theoretical concepts around NLP (or go get my PHD). That said, I have read a few and it's a damn interesting field. The problem is I need real world solutions, for real world products, in real world time frames. The problem I'm having is right now I'm not sure what the right questions are to ask to get started implementing. I believe this is mostly related to vocabulary. I'll read somewhere, a blog post, a forum post, a whitepaper, and it says, I'm doing flooping with the blargy blarg method, and I go google flooping and blargy blarg, and I get references to more obscurity. It seemingly never ends. So, my question is multiphased. First, more generally, how do I become passingly educated on this quickly? Just in time educated. I only need to know what I need to know to take the next step. I've spent 20 years writing code. Explain quick. I'll get it. (I mean provide a reference to something that explains quickly of course). I'm happy to read the right book, but I don't want to read a book where I read the chapter introduction that explains what floopy floop is and then skip over the rest of the chapter with examples of floopy flooping (because now I get what it is). I also don't want to read a book that goes into too much detail with theoretical underpinnings or history. For example, the Jurafsky book seems like way more than I need: http://www.amazon.com/gp/product/0131873210. But I will read it if this is the right book to read. (It's also dang expensive!) I need the root node of the expedited learning tree here, if you will. Point me in the right direction and I'll be quite grateful. I'm expecting quite a lot of firehose drinking - I just need the right firehose. Second, what I need to do is take a single sentence, with a very reduced vocabulary, and get a grammar tree (sorry if this is the wrong terminology) that I can do something with. I know I could easily write this command line input style in c in a more conventional manner, but I need it to be way better than that. But I don't need a chatterbot either. What I'm doing needs to live in a constrained environment. I can't use Python (unfortunately). I can't ship with gigabytes of corpuses. I need any libraries I use to be in c/c++. If I have to write this myself, I will. Hopefully, it will be achievable considering the reduced problem set. Maybe, probably, that's just naive. If so, let me know. :-) Thanks in advance - Mike

  • ASP.NET Wizard control with Dynamic UserControls

    - by wjat777
    Hello everyone I'm trying to use the Wizard control as follows: 1 - In the first step (first screen) has a cheklistbox with several options 2 - For each option selected, will be created an extra step 3 - In some steps may be set up intermediate stages Me problem is that each step is a usercontrol. So if the first step I select option1 and option3, I should create two more steps with usercontrol1 and UserControl3 .... Someone already did something similar? I will try explain better the problem. I'll paste here, but I put a copy of the project in skydrive: http://cid-3d949f1661d00819.skydrive.live.com/self.aspx/C%5E3/WizardControl2.7z It is a very basic example of what I'm trying to do. The project has page.ASPX 1 and 3 usercontrol.ASCX (UC1, UC2 and UC3) Default.ASPX: <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Default.aspx.cs" Inherits="WebApplication2._Default" % Option1 Option2 Option3 Code Behind: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication2 { public partial class _Default : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { } protected void Page_PreInit(object sender, EventArgs e) { LoadSteps(); } private void LoadSteps() { int count = Wizard1.WizardSteps.Count; for (int i = count - 1; i > 0; i--) { WizardStepBase step = Wizard1.WizardSteps[i]; if (step.StepType != WizardStepType.Start) Wizard1.WizardSteps.Remove(step); } string Activities=""; foreach (ListItem item in CheckBoxList1.Items) { if (item.Selected) { WizardStep step = new WizardStep {ID = "step_" + item.Value, Title = "step_" + item.Value}; UserControl uc=null; switch (item.Value) { case "1": uc=(UserControl)LoadControl("~/UC1.ascx"); break; case "2": uc=(UserControl)LoadControl("~/UC2.ascx"); break; case "3": uc=(UserControl)LoadControl("~/UC3.ascx"); break; } step.Controls.Add(uc); Wizard1.WizardSteps.Add(step); } } } protected void CheckBoxList1_SelectedIndexChanged(object sender, EventArgs e) { LoadSteps(); } } } Control UC1.ASCX to UC3.ASCX has the same code (as an example) usercontrol.ascx: <%@ Control Language="C#" AutoEventWireup="true" CodeBehind="UC1.ascx.cs" Inherits="WebApplication2.UC1" % AutoPostBack="True" AutoPostBack="True" Code Behind: using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication2 { public partial class UC1 : System.Web.UI.UserControl { protected void Page_Init(object sender, EventArgs e) { List list1 = new List { "Alice", "Bob", "Chris" }; List list2 = new List { "UN", "DEUX", "TROIS" }; DropDownList1.DataSource = list1; DropDownList2.DataSource = list2; DropDownList1.DataBind(); DropDownList2.DataBind(); } protected void Page_Load(object sender, EventArgs e) { if (IsPostBack) return; } protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) { Label1.Text = DropDownList1.SelectedValue; } protected void DropDownList2_SelectedIndexChanged(object sender, EventArgs e) { Label2.Text = DropDownList2.SelectedValue; } } } You can see that the controls UserControls trigger events (they cause postbacks) The behavior of this project is a little different than I described in the first thread, but the problem is the same. After the second time "next" button, you will get an error. Thanks in advance William

  • Rails HABTM accepts_nested_attributes_for mapping table

    - by Rabbott
    Currently I have a habtm relationship between a datastream (stream), and a chart. I want to be able to use the 'typical' jquery "add new stream" method to add a new entry into a mapping table that holds the chart_id, and stream_id.. But I think that most examples out there are made to handle a one to many relationship.. The functionality provided here by Ryan Bates is what I'm looking for, But I dont want to use checkboxes, I want to use a select (drop down) to add new items to the mapping table. I need THIS and THIS combined chart.rb class Chart < ActiveRecord::Base has_and_belongs_to_many :streams, :readonly => false, :join_table => 'charts_streams' accepts_nested_attributes_for :streams, :reject_if => lambda { |a| a.values.all?(&:blank?) }, :allow_destroy => true stream.rb class Stream < ActiveRecord::Base has_and_belongs_to_many :charts, :readonly => false, :join_table => 'charts_streams' application.js /* * Method used to add new child form partials */ $('form a.add_child').click(function() { var assoc = $(this).attr('data-association'); var content = $('#' + assoc + '_fields_template').html(); var regexp = new RegExp('new_' + assoc, 'g'); var new_id = new Date().getTime(); var newElements = jQuery(content.replace(regexp, new_id)).hide(); $(this).parent().before(newElements).prev().slideFadeToggle(); return false; }); /* * Method used to remove child form partials */ $('form a.remove_child').live('click', function() { if(confirm('Are you sure?')) { var hidden_field = $(this).prev('input[type=hidden]')[0]; if(hidden_field) { hidden_field.value = '1'; } $(this).parents('.fields').slideFadeToggle(); } return false; }); _form.html.erb <div id="streams"> <h4>Streams</h4> <% form.fields_for :streams do |stream_form| %> <%= render :partial => "stream", :locals => {:f => stream_form} %> <% end %> </div> <p><%= add_child_link 'Add a stream', :streams %></p> <%= new_child_fields_template(form, :streams) %> _stream.html.erb <div class="fields"> <p> <%= f.label :stream_id %><br /> <%= select_tag "chart[stream_ids][]", options_for_select(@streams.map {|s| [s.label, s.id]}, f.object.id) %> </p> <p><%= remove_child_link 'Remove stream', f %></p> </div> This may be overkill and what I am looking to do could be much easier.. Basically when I create a chart I want to be able to add as many streams to it as I want, using the javascript for adding a new entry, and removing an old one... Thanks for the help! This is 'working' but gives me a ActiveRecord::ReadOnlyRecord error when it hits the chart.update_attributes method.. am I adding the the :readonly = false in the wrong spot? Or am I just doing it completely wrong?

  • Help with SVN+SSH permissions with CentOS/WHM setup

    - by Furiam
    Hi Folks, I'll try my best to explain how I'm trying to set up this system. Imagine a production server running WHM with various sites. We'll call these sites... site1, site2, site2 Now, with the WHM setup, each site has a user/group defined for them, we'll keep these users/groups called site1,site2 for simplicity reasons. Now, updating these sites is accomplished using SVN, and through the use of a post commit script to auto update these sites (With .svn blocked through the apache configuration). There are two regular maintainers of these sites, we'll call them Joe and Bob. Joe and Bob both have commandline access to the server through thier respective limited accounts. So I've done the easy bit, managed to get SVN working with these "maintainers" so that when an SVN commit occurs, the changes are checked out and go live perfectly. Here's the cavet, and ultimately my problem. User permissions. Through my testing of this setup, I've only managed to get it working by giving what is being updated permissions of 777, so that Joe and Bob can both read and write access to webfront directories for each of the sites. So, an example of how it's set up now: Joe and Bob both belong to a group called "Dev". I have the master /svn folders set up for both read and write access to this group, and it works great. Post commit triggers, updates the site, and then sets 777 on each file within the webfront. I then changed this to try and factor in group permission updates, instead of straight 777. Each folder in /home/site1/public_html intially gets given a chmod of 664, and each folder 775 Which looks a little something like this drwxrwxr-x . drwxrwxr-x .. drwxrwxr-x site1 site1 my_test_folder -rw-rw-r-- site1 site1 my_test_file So site1 is sthe owner and group owner of those files and folders. So I then added site1 to Joe and Bobs secondary groups so that the SVN update will correctly allow access to these files. Herein lies the problem now. When I wish to add a file or folder to /home/site1, say Bobs_file, it then looks like this drwxrwxr-x . drwxrwxr-x .. drwxr-xr-x Bob dev bobs_folder drwxrwxr-x site1 site1 my_test_folder -rw-rw-r-- Bob dev bobs_file -rw-rw-r-- site1 site1 my_test_file How can I get it so that with the set of user permissions Bob has available, to change the owner and group owner of that file to reflect "site1" "site1". As Bob belongs to Dev I can set the permissions correctly with CHMOd, but It appears CHGRP is throwing back operation errors. Now this was long winded enough to give an overview of exactly what I'm trying to accomplish, just incase I'm going about this arse-over-tit and there's a far easier solution. Here's my goals 2 people to update multiple user accounts specified given the structure of WHM Trying to maintain master user/group permissions of file and folders to the original user account, and not the account of the updatee. I like the security of SVN+SSH over just SVN. Don't want to run all this over root. I hope this made sense, and thanks in advance :)

  • How to Access a descendant object's internal method in C#

    - by Giovanni Galbo
    I'm trying to access a method that is marked as internal in the parent class (in its own assembly) in an object that inherits from the same parent. Let me explain what I'm trying to do... I want to create Service classes that return IEnumberable with an underlying List to non-Service classes (e.g. the UI) and optionally return an IEnumerable with an underlying IQueryable to other services. I wrote some sample code to demonstrate what I'm trying to accomplish, shown below. The example is not real life, so please remember that when commenting. All services would inherit from something like this (only relevant code shown): public class ServiceBase<T> { protected readonly ObjectContext _context; protected string _setName = String.Empty; public ServiceBase(ObjectContext context) { _context = context; } public IEnumerable<T> GetAll() { return GetAll(false); } //These are not the correct access modifiers.. I want something //that is accessible to children classes AND between descendant classes internal protected IEnumerable<T> GetAll(bool returnQueryable) { var query = _context.CreateQuery<T>(GetSetName()); if(returnQueryable) { return query; } else { return query.ToList(); } } private string GetSetName() { //Some code... return _setName; } } Inherited services would look like this: public class EmployeeService : ServiceBase<Employees> { public EmployeeService(ObjectContext context) : base(context) { } } public class DepartmentService : ServiceBase<Departments> { private readonly EmployeeService _employeeService; public DepartmentService(ObjectContext context, EmployeeService employeeService) : base(context) { _employeeService = employeeService; } public IList<Departments> DoSomethingWithEmployees(string lastName) { //won't work because method with this signature is not visible to this class var emps = _employeeService.GetAll(true); //more code... } } Because the parent class lives is reusable, it would live in a different assembly than the child services. With GetAll(bool returnQueryable) being marked internal, the children would not be able to see each other's GetAll(bool) method, just the public GetAll() method. I know that I can add a new internal GetAll method to each service (or perhaps an intermediary parent class within the same assembly) so that each child service within the assembly can see each other's method; but it seems unnecessary since the functionality is already available in the parent class. For example: internal IEnumerable<Employees> GetAll(bool returnIQueryable) { return base.GetAll(returnIQueryable); } Essentially what I want is for services to be able to access other service methods as IQueryable so that they can further refine the uncommitted results, while everyone else gets plain old lists. Any ideas? EDIT You know what, I had some fun playing a little code golf with this... but ultimately I wouldn't be able to use this scheme anyway because I pass interfaces around, not classes. So in my example GetAll(bool returnIQueryable) would not be in the interface, meaning I'd have to do casting, which goes against what I'm trying to accomplish. I'm not sure if I had a brain fart or if I was just too excited trying to get something that I thought was neat to work. Either way, thanks for the responses.

  • Problem Registering a Generic Repository with Windsor IoC

    - by Robin
    I’m fairly new to IoC and perhaps my understanding of generics and inheritance is not strong enough for what I’m trying to do. You might find this to be a mess. I have a generic Repository base class: public class Repository<TEntity> where TEntity : class, IEntity { private Table<TEntity> EntityTable; private string _connectionString; private string _userName; public string UserName { get { return _userName; } set { _userName = value; } } public Repository() {} public Repository(string connectionString) { _connectionString = connectionString; EntityTable = (new DataContext(connectionString)).GetTable<TEntity>(); } public Repository(string connectionString, string userName) { _connectionString = connectionString; _userName = userName; EntityTable = (new DataContext(connectionString)).GetTable<TEntity>(); } // Data access methods ... ... } and a SqlClientRepository that inherits Repository: public class SqlClientRepository : Repository<Client> { private Table<Client> ClientTable; private string _connectionString; private string _userName; public SqlClientRepository() {} public SqlClientRepository(string connectionString) : base(connectionString) { _connectionString = connectionString; ClientTable = (new DataContext(connectionString)).GetTable<Client>(); } public SqlClientRepository(string connectionString, string userName) : base(connectionString, userName) { _connectionString = connectionString; _userName = userName; ClientTable = (new DataContext(connectionString)).GetTable<Client>(); } // data access methods unique to Client repository ... } The Repository class provides some generics methods like Save, Delete, etc, that I want all my repository derived classes to share. The TEntity parameter is constrained to the IEntity interface: public interface IEntity { int Id { get; set; } NameValueCollection GetSaveRuleViolations(); NameValueCollection GetDeleteRuleViolations(); } This allows the Repository class to reference these methods within its Save and Delete methods. Unit tests work fine on mock SqlClientRepository instances as well as live unit tests on the real database. However, in the MVC context: public class ClientController : Controller { private SqlClientRepository _clientRepository; public ClientController(SqlClientRepository clientRepository) { this._clientRepository = clientRepository; } public ClientController() { } // ViewResult methods ... ... } ... _clientRepository is always null. I’m using Windor Castle as an IoC container. Here is the configuration: <component id="ClientRepository" service="DomainModel.Concrete.Repository`1[[DomainModel.Entities.Client, DomainModel]], DomainModel" type="DomainModel.Concrete.SqlClientRepository, DomainModel" lifestyle="PerWebRequest"> <parameters> <connectionString>#{myConnStr}</connectionString> </parameters> </component> I’ve tried many variations in the Windsor configuration file. I suspect it’s more of a design flaw in the above code. As I'm looking over my code, it occurs to me that when registering components with an IoC container, perhaps service must always be an interface. Could this be it? Does anybody have a suggestion? Thanks in advance.

  • Strategy and AI for the game 'Proximity'

    - by smci
    'Proximity' is a strategy game of territorial domination similar to Othello, Go and Risk. Two players, uses a 10x12 hex grid. Game invented by Brian Cable in 2007. Seems to be a worthy game for discussing a) optimal strategy then b) how to build an AI Strategies are going to be probabilistic or heuristic-based, due to the randomness factor, and the high branching factor (starts out at 120). So it will be kind of hard to compare objectively. A compute time limit of 5s per turn seems reasonable. Game: Flash version here and many copies elsewhere on the web Rules: here Object: to have control of the most armies after all tiles have been placed. Each turn you received a randomly numbered tile (value between 1 and 20 armies) to place on any vacant board space. If this tile is adjacent to any ally tiles, it will strengthen each tile's defenses +1 (up to a max value of 20). If it is adjacent to any enemy tiles, it will take control over them if its number is higher than the number on the enemy tile. Thoughts on strategy: Here are some initial thoughts; setting the computer AI to Expert will probably teach a lot: minimizing your perimeter seems to be a good strategy, to prevent flips and minimize worst-case damage like in Go, leaving holes inside your formation is lethal, only more so with the hex grid because you can lose armies on up to 6 squares in one move low-numbered tiles are a liability, so place them away from your main territory, near the board edges and scattered. You can also use low-numbered tiles to plug holes in your formation, or make small gains along the perimeter which the opponent will not tend to bother attacking. a triangle formation of three pieces is strong since they mutually reinforce, and also reduce the perimeter Each tile can be flipped at most 6 times, i.e. when its neighbor tiles are occupied. Control of a formation can flow back and forth. Sometimes you lose part of a formation and plug any holes to render that part of the board 'dead' and lock in your territory/ prevent further losses. Low-numbered tiles are obvious-but-low-valued liabilities, but high-numbered tiles can be bigger liabilities if they get flipped (which is harder). One lucky play with a 20-army tile can cause a swing of 200 (from +100 to -100 armies). So tile placement will have both offensive and defensive considerations. Comment 1,2,4 seem to resemble a minimax strategy where we minimize the maximum expected possible loss (modified by some probabilistic consideration of the value ß the opponent can get from 1..20 i.e. a structure which can only be flipped by a ß=20 tile is 'nearly impregnable'.) I'm not clear what the implications of comments 3,5,6 are for optimal strategy. Interested in comments from Go, Chess or Othello players. (The sequel ProximityHD for XBox Live, allows 4-player -cooperative or -competitive local multiplayer increases the branching factor since you now have 5 tiles in your hand at any given time, of which you can only play one. Reinforcement of ally tiles is increased to +2 per ally.)

  • Freezes (not crashes) with GCD, blocks and Core Data

    - by Lukasz
    I have recently rewritten my Core Data driven database controller to use Grand Central Dispatch to manage fetching and importing in the background. Controller can operate on 2 NSManagedContext's: NSManagedObjectContext *mainMoc instance variable for main thread. this contexts is used only by quick access for UI by main thread or by dipatch_get_main_queue() global queue. NSManagedObjectContext *bgMoc for background tasks (importing and fetching data for NSFetchedresultsController for tables). This background tasks are fired ONLY by user defined queue: dispatch_queue_t bgQueue (instance variable in database controller object). Fetching data for tables is done in background to not block user UI when bigger or more complicated predicates are performed. Example fetching code for NSFetchedResultsController in my table view controllers: -(void)fetchData{ dispatch_async([CDdb db].bgQueue, ^{ NSError *error = nil; [[self.fetchedResultsController fetchRequest] setPredicate:self.predicate]; if (self.fetchedResultsController && ![self.fetchedResultsController performFetch:&error]) { NSSLog(@"Unresolved error in fetchData %@", error); } if (!initial_fetch_attampted)initial_fetch_attampted = YES; fetching = NO; dispatch_async(dispatch_get_main_queue(), ^{ [self.table reloadData]; [self.table scrollRectToVisible:CGRectMake(0, 0, 100, 20) animated:YES]; }); }); } // end of fetchData function bgMoc merges with mainMoc on save using NSManagedObjectContextDidSaveNotification: - (void)bgMocDidSave:(NSNotification *)saveNotification { // CDdb - bgMoc didsave - merging changes with main mainMoc dispatch_async(dispatch_get_main_queue(), ^{ [self.mainMoc mergeChangesFromContextDidSaveNotification:saveNotification]; // Extra notification for some other, potentially interested clients [[NSNotificationCenter defaultCenter] postNotificationName:DATABASE_SAVED_WITH_CHANGES object:saveNotification]; }); } - (void)mainMocDidSave:(NSNotification *)saveNotification { // CDdb - main mainMoc didSave - merging changes with bgMoc dispatch_async(self.bgQueue, ^{ [self.bgMoc mergeChangesFromContextDidSaveNotification:saveNotification]; }); } NSfetchedResultsController delegate has only one method implemented (for simplicity): - (void)controllerDidChangeContent:(NSFetchedResultsController *)controller { dispatch_async(dispatch_get_main_queue(), ^{ [self fetchData]; }); } This way I am trying to follow Apple recommendation for Core Data: 1 NSManagedObjectContext per thread. I know this pattern is not completely clean for at last 2 reasons: bgQueue not necessarily fires the same thread after suspension but since it is serial, it should not matter much (there is never 2 threads trying access bgMoc NSManagedObjectContext dedicated to it). Sometimes table view data source methods will ask NSFetchedResultsController for info from bgMoc (since fetch is done on bgQueue) like sections count, fetched objects in section count, etc.... Event with this flaws this approach works pretty well of the 95% of application running time until ... AND HERE GOES MY QUESTION: Sometimes, very randomly application freezes but not crashes. It does not response on any touch and the only way to get it back to live is to restart it completely (switching back to and from background does not help). No exception is thrown and nothing is printed to the console (I have Breakpoints set for all exception in Xcode). I have tried to debug it using Instruments (time profiles especially) to see if there is something hard going on on main thread but nothing is showing up. I am aware that GCD and Core Data are the main suspects here, but I have no idea how to track / debug this. Let me point out, that this also happens when I dispatch all the tasks to the queues asynchronously only (using dispatch_async everywhere). This makes me think it is not just standard deadlock. Is there any possibility or hints of how could I get more info what is going on? Some extra debug flags, Instruments magical tricks or build setting etc... Any suggestions on what could be the cause are very much appreciated as well as (or) pointers to how to implement background fetching for NSFetchedResultsController and background importing in better way.

  • 3D game engine for networked world simulation / AI sandbox

    - by Martin
    More than 5 years ago I was playing with DirectSound and Direct3D and I found it really exciting although it took much time to get some good results with C++. I was a college student then. Now I have mostly enterprise development experience in C# and PHP, and I do it for living. There is really no chance to earn money with serious game development in our country. Each day more and more I find that I miss something. So I decided to spend an hour or so each day to do programming for fun. So my idea is to build a world simulation. I would like to begin with something simple - some human-like creatures that live their life - like Sims 3 but much more simple, just basic needs, basic animations, minimum graphic assets - I guess it won't be a city but just a large house for a start. The idea is to have some kind of a server application which stores the world data in MySQL database, and some client applications - body-less AI bots which simulate movement and some interactions with the world and each other. But it wouldn't be fun without 3D. So there are also 3D clients - I can enter that virtual world and see the AI bots living. When the bot enters visible area, it becomes material - loads a mesh and animations, so I can see it. When I leave, the bots lose their 3d mesh bodies again, but their virtual life still continues. With time I hope to make it like some expandable scriptable sandbox to experiment with various AI algorithms and so on. But I am not intended to create a full-blown MMORPG :D I have looked for many possible things I would need (free and open source) and now I have to make a choice: OGRE3D + enet (or RakNet). Old good C++. But won't it slow me down so much that I won't have fun any more? CrystalSpace. Formally not a game engine but very close to that. C++ again. MOgre (OGRE3D wrapper for .NET) + lidgren (networking library which is already used in some gaming projects). Good - I like C#, it is good for fast programming and also can be used for scripting. XNA seems just a framework, not an engine, so really have doubts, should I even look at XNA Game Studio :( Panda3D - full game engine with positive feedback. I really like idea to have all the toolset in one package, it has good reviews as a beginner-friendly engine...if you know Python. On the C++ side, Panda3D has almost non-existent documentation. I have 0 experience with Python, but I've heard it is easy to learn. And if it will be fun and challenging then I guess I would benefit from experience in one more programming language. Which of those would you suggest, not because of advanced features or good platform support but mostly for fun, easy workflow and expandability, and so I can create and integrate all the components I need - the server with the database, AI bots and a 3D client application?
