  • Configure ApacheDS 1.5 with accessControlEnabled=true for authenticated access

    - by cmyers
    I need to set up an apacheDS instance. I am using standalone 1.5.5 on Linux. I have removed the example partition and added two of my own, each with their own suffixes. I have imported LDIFs for the two partitions and everything looks correct data-wise. I need to configure ApacheDS to disallow anonymous access. I was able to do that by following some of the directions here: http://directory.apache.org/apacheds/1.5/145-enable-and-disable-anonymous-access.html http://directory.apache.org/apacheds/1.5/32-basic-authorization.html Now only the administrator account (uid=admin,ou=system) can log in and make queries. I need to establish an admin account, and a "regular user" account which can read and write only certain entries within each partition. I tried to read the above docs and I got nuthin'. The second page "basic authorization" is completely incomprehensible to me. When I tried to add a "prescriptiveACI" to it using Apache Directory Studio, I get: Administration point 2.5.4.11=abc,2.5.4.10=efg does not contain an administrativeRole attribute! An administrativeRole attribute in the administrative point is required to add a subordinate subentry. where my partition is "ou=abc,o=def". I have no clue what is going on and the docs are really not helping, I am at a complete loss here. How can it possibly be this hard to just restrict access? P.S. can someone with proper rep please change the tag "apache" to the new tag "ApacheDS"?

  • Virtualbox HTTP load testing, host CPU overload issues

    - by aschuler
    I'm doing HTTP load testing benchmarks (using Apache Benchmark and Siege) on a small Java EE 1.7.0 / Tomcat 7.0.26 application running on a Debian Squeeze 6.0.4 x64 virtualized with Virtualbox 4.1.8. The computer host is Ubuntu 11.10 x64. I've modified those parameters in the Tomcat server.xml : <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="200000" redirectPort="8443" acceptCount="2000" maxThreads="150" minSpareThreads="50" /> The application executed on the server takes around 300ms. This app is running well until a certain amount of concurrent connections like those one : ab -n 500 -c 150 http://xx.xx.xx.xx:8080/myapp/ ab -n 1000 -c 50 http://xx.xx.xx.xx:8080/myapp/ siege -b -c 100 -r 20 http://xx.xx.xx.xx:8080/myapp/ A lot of socket connection timed out happens and this completly overload the host processor (but the CPU load inside the VM is normal). Doing an htop on the host, i can see that the Virtualbox processus is running under 300% CPU and never come down even after the load test is finished. (I've allocated 4 processors to the VM, if I allocate only one processor, CPU load goes under 100%). Restarting Tomcat don't do anything, i'm forced to restart the whole VM. I've tryed to launch those ab/siege commands locally on the VM and everything goes well. I first thought it was related to a linux network limit as explained here: Running some benchmarks using ab, and tomcat starts to really slow down So I've modified those TCP parameters : echo 15 > /proc/sys/net/ipv4/tcp_fin_timeout echo 30 > /proc/sys/net/ipv4/tcp_keepalive_intvl echo 1 > /proc/sys/net/ipv4/tcp_tw_recycle echo 1 > /proc/sys/net/ipv4/tcp_tw_reuse It seems to be better, but it continues to overload the host CPU and output socket connections time out at a certain amount of concurrent connections. I'm wondering if this is not related to how Virtualbox handles external concurrent connections.

  • Preventing Windows version of Vim from destroying other file systems permissions

    - by dborba
    I am currently using the windows version of gVim to edit source files on a networked drive mapped to a linux system, as well as local files created in cygwin. The problem is that the windows version of gVim destroys the original file permissions on the respective systems. IE: Files on cygwin are defaulted to 077. When edited by the windows version of vim they are saved as 777.This problem doesn't even occur when using ms-notepad (as well as all other editors I've tried), so I am not quite sure why gVim does it. A possible solution would be to use cygwin's gVim for everything, but that's rather cumbersome as it requires running an x11 environment to support it, and it causes some problems when running some commands from within gVim (or vim for that matter) when working on the networked drive. Any ideas how I might be able to maintain the existing file permissions? Edit: This morning while on a different machine the problem with cygwin did not occur. Cygwin & gVim were the same version, however the other machine is running WinXP while the machine the problem is occurring on runs Win7.

  • Viewing a large-resolution VNC server through a small-resolution viewer in Ubuntu

    - by Madiyaan Damha
    I have two Ubuntu computers, one with a large screen resolution (1920x1600) that is running default ubuntu vnc server. I have another computer that has a resolution of about 1200x1024 that I use to vnc into the server (I use the default ubuntu vnc viewer). Now everything works fine except there are annoying scrollbars in the viewer because the server's desktop resolution is so much higher than the viewer's. Is there a way to: 1) Scale the server's desktop down to the viewer's resolution. I know there will be a loss of image quality, but I am willing to try it out. This should be something like how windows media player or vlc scales down the window (and does some interpolation of pixels). 2) Automatically shrink the resolution of the server to the client's when I connect and scale the resolution back when I disconnect. This seems like a less attractive solution. 3) Any other solution that gurus out there use? I am sure someone has experienced this before (annoying scroll bars) so there must be a solution out there. Thanks,

  • SQL Server 2008 login problem with ASP.NET application: Failed to open the explicitly specified data

    - by eulerfx
    I am running SQL Server 2008 Express Edition on Windows Server 2008 with an ASP.NET application which must access the server. The ASP.NET application is associated with an application pool that runs on the NetworkService account. This account in turn has a Login and User record on SQL Server in the required database. When I attempt to run the ASP.NET website I get a blank page and when viewed in the error log, I seem to be getting this information event record: Login failed for user 'NT AUTHORITY\NETWORK SERVICE'. Reason: Failed to open the explicitly specified database. [CLIENT: myLocalMachine] The connection string has Trusted_Connection=True; and the required database specified. When I explicitly specify the user name and password I get another login error stating the password is incorrect, even though the same un/pw combination works through SQL Server Management studio. The NETWORK SERVICE account seems to have all the required privileges for the database. Also, I made a test ASP.NET website project which does a simple select from a table in that database, and using the same config file I am not getting the error and it seems to work. Is it something to do with trust levels then, because the original ASP.NET web app references various DLLs including open source libraries. Also, the application does not seem to be able to write to the event log itself, throwing a security exception, even though everything in the config files, including machine.config states the app is in full trust.

  • Explorer and open file dialog not responding (Vista)

    - by rohancragg
    Any explorer window opened for the first time on my machine causes the explorer window to display the folders tree and folder path in the address bar immediately but the file/folder list pane is blank and the window displays 'Not Responding' in the title bar, this hangs for up to a minute or more. Any file dialog displays 'Not Responding' in the title bar. The files list is eventually displayed after a few seconds or more. Steps to repro: Close all open instances of explorer Windows Key | Run | [enter a folder path such as 'c:\temp'] Or within any app: use a file open / save dialog Once there is at least one open instance of explorer the performance is still fairly poor but not nearly so bad and file lists are displayed in a timely fashion. What I've tried: Cleaned up registry with CCleaner tool, and uninstalled all other unused software Checked nothing unwanted running at startup with Autoruns Removed any ISO burner/recorder/mount software Still to try Get latest version of everything - especially stuff with shell extension behaviour such as TortoiseSVN Anyone have any other suggestions? Thanks alot. Update I'm wondering if this is related, I'll try the hotfix when I get home and report back: KB972685 - FIX:Explorer.exe hangs when using a shell extension written using MFC Update 2 Before I got a chance to try the hotfix it seems one of the above actions fixed this for me; either the removal of IsoRecorder or TortoiseHg (which I was no longer using anyway). Update 3 A similar issue with Explorer.exe has come back since installing TortoiseHg 1.01 :-(

  • Is there a way to know what the Windows Disk Cleanup utility will delete?

    - by Cam Jackson
    When I run the Disk Cleanup utility that's built into Windows 8, it tells me that it can free up 53GB by deleting 'Temporary Files'. However, a CCleaner analysis on default settings only finds about 300MB worth of space to free up, so I'm wondering what Disk Cleanup has found that CCleaner does not. Note that this question appears to be similar to what I'm asking, but the accepted answer says that 'Temporary Files' refers to %TEMP%. I've already cleared out most of C:\Users\Cam\AppData\Local\Temp, and it now has only 230MB of stuff in it, even with system files showing. So where is this 53GB located? Is there a way to find out what it is? Edit: I should note that this is on a 110GB SSD, so it's almost half the drive. And in fact I'm only using 86GB, so if it's really going to clear out 53GB, that would be more than 60% of the stuff on my C drive. I'm starting to think that Disk Cleanup caches its analysis, and hasn't updated since I started cleaning up the drive earlier today. Although when I run it it says that it's 'Calculating' how much space can be saved, and it takes about 5-10 seconds to do so. Hmmm... Edit2: Here is what my hard drive looks like, according to SpaceMonger (Right click-Open image in new tab, so you can see it properly): You can see why I was starting to think that the 53GB figure is actually wrong. Even if 'Temporary Files' includes my hiberfil and everything in WinSxS (about 13GB total), that would be 26GB, which is only halfway there. Hard to see where there's 53GB of stuff to delete.

  • 2 Server FC SAN Configuration

    - by BSte
    I have 2 identical servers: -48GB Ram -8GigE NIC's -2FC NIC's -2x72GB RAID1 Hard Drives -Server 2008R2 Host I also Have a Fibre Channel SAN: -16x146GB RAID10 Hard Drives -2xDual-port FC Controllers (Controller A and B both have ports 1 and 2) -Server 1 has Fiber to Ports A1 and B1 -Server 2 has Fiber to Ports A2 and B2 -I kept the default config with 1 Virtual Disk and 1 Volume -The default mappings show ports A1,A2,B1,B2 on LUN 0 with read-write My goal is: -2xVM's with IIS and Guest Level Failover -2xVM's with SQL 2008 Enterprise using a Single DB and Guest Level Failover -1xVM that is an application server, preferable with Host Failover. From what I read, this will also need AD for clustering to work. -I need at least 1 VM always running for IIS and the SQLDB. This includes hardware failover and application (ie: reboot a VM for Critical updates) I was told I could install the VM's and run them from the SAN, and this is what I've tried: Installed MPIO and HyperV on Server1 and Server 2 Added the SAN as Disk E: on both servers, made it GPT and formatted NTFS Configured HyperV on both server to store use E:\VD and E:\VHD On server1, I was able to install 3 VM's on the SAN and all worked well. On server2, I would start installing the other 2 VM's, but always at some point the VM's would get a corrupt .VHD message (either server). Everything I found about the message typically related to antivirus, so I removed all antivirus on both Host servers (now only running 2008R2). I reformatted drive E: (SAN), recreated the VHD and VD directories, installed 3 VM's on Server 1, and then had the same issue when installing VM's on Server2. Obviously something is wrong, but I'm not certain what exactly. My questions: 1) Are my goals possible with this hardware setup? -I've read 2008R2 supports FC SAN's, but a lot of articles seem to only give examples with iSCSCI setups 2) What would be the suggested route on setting up the SAN (disks,volumes,LUN's)? I've worked with HyperV on a single machine before and never had issues. Actual experience working on SAN's and clustering is new to me. Any suggestions or recommendations to get me in the right direction would be much appreciated.

  • Outside VPN traffic not able to ping site-to-site VPN remote site

    - by Siriss
    we have two ASA 5510s running 8.4 in a site-to-site VPN setup. All internal traffic is working smoothly. Site/Subnet A: 192.100.0.0 - local Site/Subnet B: 192.200.0.0 - remote VPN Users: 192.100.40.0 - assigned by ASA When you VPN into the network, all traffic hits Site A, and everything on subnet A is accessible. Site B however, is completely inaccessible for VPN users. All machines on subnet B, the firewall itself, etc... is not reachable by ping or otherwise. I know I am missing a NAT rule, and in 8.2, it was easy as pie to setup using ASDM, but now I can't get it for the life of me as 8.4 apparently made a lot of changes to NAT rules. I am not too comfortable in the ASA command line, but if there is a command I need to add or if you could direct me where I can add this in 8.4 ASDM I would really appreciate it. I have tired NAT Exempt, Static NAT, Static NAT Policies, etc... I think I tried all the options. I also might have my interfaces confused with the new look at feel of ASDM. Thank you much in advance and I hope I have been thorough enough.

  • Amazon AWS EC2 + Puppet, get Puppet to know AWS instance tags

    - by Piotr Jasiulewicz
    I am having a problem with my AWS deployment, fairly new to AWS and Puppet. So coming to my question - can you distinguish puppet nodes with AWS machine tags or CNAME domains? A little background about the plan: have multiple clusters of machines, one php cluster, one legacy php cluster, one java cluster, one perl cluster control configuration with puppet - still pretty new to puppet but as a developer I like the idea of being able to version control configuration of servers have autoscaling enabled on those clusters - obviously the main benefit of the cloud that makes the much hight cost when it comes to any reasonable performance worth it (those amazon machines are slower than my phone...) deployment controlled by Capistrano, this makes things a lot easier So in AWS you get those super nasty public/private machine dns's... no way you can identify machines on those. In order to easer the problem, seams like AWS want's you to tag everything - so I did. Found a script that makes a CNAME record for each machine with the tag "ShortName" thanks to the Route53 API. Every machine has a ShortName tag that becomes its CNAME, unfortunately puppet still resolves the private dns name. I'd like to have node 'perl-cluster'{} in puppet, anyone any clue ho to achieve this? Thanks

  • How do I find out the Mac Address Firefox submits for Geolocation?

    - by Jim McKeeth
    I moved, but have the same router and cable box. Now when I visit Google Maps it still shows my old location. I went to the SkyhookWireless update page to update my Mac Address with my new location. The process is you put in your Mac address and it shows you the current location, and then you adjust that location and submit it. When I got the Mac Address from the status page on my router Skyhook reported that location as in Pakistan, which isn't even the correct continent (as my old or new address). I tried every other Mac address I could come up with: The cable router, the Wireless router's other Mac address, my PC's Mac address, etc. and none of them reported any location on the Skyhook page. So I am guessing that there is another Mac address, or some other bit of information that is used by Firefox when it reports to Google Maps my current location. Now that you have the back story, how do I find the Mac address or whatever information it is that Firefox (or other browsers) use to determine my Geolocation? Everything I have read online is rather vague. The next option I am considering is hooking a logging proxy onto Firefox and seeing what data it sends, but I'd rather find an easier method. Related: How do I update the geo location of my house?

  • Exim rejects recipient address on my domain

    - by Nicolas
    Hi, I have a dedicated server (debian) on which I have installed Exim and Dovecot. Everything worked fine until around a month ago. I tried to reinstall and reconfigure exim but I keep having all the incoming emails rejected. Outlook says: A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: [email protected] SMTP error from remote mail server after RCPT TO:: host mail.mydomain.com [94.76.##.##]: 550 relay not permitted GMAIL: Delivery to the following recipient failed permanently: [email protected] Technical details of permanent failure: Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 550 550 relay not permitted (state 14).

Oh and the PHP mail() function does not do anything as well, would it be linked to? I think mail() uses sendmail from my php.ini.

  • Java Plugin a huge security risk? How to preseve Java plugin from privilege escalation?

    - by Johannes Weiß
    Installing a regular Java plugin is IMHO a real security risk for non-IT people. Normally Java applets run in a sandbox and the applet cannot do anything harmful to your computer. If an applet, however, needs to do something like read-only accessing your filesystem e.g. uploading an image, you have to give it more privileges. Usually that's ok but I think not everyone knows that you give the applet the same privileges to your computer as your user has! And that's everything Java asks you: That looks as 'harmful' as a self-signed SSL certificate on a random page where no sensitive data is exchanged. The user will click on Run! You can try that at home using JyConsole, that's Jython (Python on Java)! Simply type in python code, e.g. import os os.system('cat /etc/passwd') or worse DON'T TYPE IN THAT CODE ON YOUR COMPUTER!!! import os os.system('rm -rf ~') ... Does anyone know how you can disable the possibily of privilege escalation? And by the way, does anyone know why SUN displays only a dialog as harmless as the one shown above (the self-signed-SSL-certificate-dialog from Firefox 3 and above is much clearer here!)? Live sample from my computer:

  • Blocking requests from specific IPs using IIS Rewrite module

    - by Thomas Levesque
    I'm trying to block a range of IP that is sending tons of spam to my blog. I can't use the solution described here because it's a shared hosting and I can't change anything to the server configuration. I only have access to a few options in Remote IIS. I see that the URL Rewrite module has an option to block requests, so I tried to use it. My rule is as follows in web.config: <rule name="BlockSpam" enabled="true" stopProcessing="true"> <match url=".*" /> <conditions logicalGrouping="MatchAll" trackAllCaptures="false"> <add input="{REMOTE_ADDR}" pattern="10\.0\.146\.23[0-9]" ignoreCase="false" /> </conditions> <action type="CustomResponse" statusCode="403" /> </rule> Unfortunately, if I put it at the end of the rewrite rules, it doesn't seem to block anything... and if I put it at the start of the list, it blocks everything! It looks like the condition isn't taken into account. In the UI, the stopProcessing option is not visible and is true by default. Changing it to false in web.config doesn't seem to have any effect. I'm not sure what to do now... any ideas?

  • Apache MaxClients reaching max and locking the server

    - by Rodrigo Sieiro
    Hi. I currently have an Apache2 server running with mpm-prefork and mod_php on a OpenVZ VPS with 512M real / 1024M burstable RAM (no swap). After running some tests, I found that the maximum process size Apache gets is 23M, so I've set MaxClients to 25 (23M x 25 = 575 MB, ok for me). I decided to run some load tests on my server, and the results left me puzzled. I'm using ab on my desktop machine requesting the main page from a wordpress blog. When I run ab with 24 concurrent connections, everything seems fine. Sure, CPU goes up, free RAM goes down, and the result is about 2-3s response time per request. But if I run ab with 25 concurrent connections (my server limit), Apache just hangs after a couple of seconds. It starts processing the requests, then it stops responding, CPU goes back to 100% idle and ab times out. Apache log says it reached MaxClients. When this happens, Apache keeps itself locked up with 25 running processes (they're all in "W" if I check server status) and only after the TimeOut setting the processes start to die and the server starts responding again (in my case it's set to 45). My question: is that expected behaviour? Why Apache just dies when it reaches MaxClients? If it works with 24 connections, shouldn't it work with 25, just taking maybe more time to respond each request and queueing up the rest? It sounds kinda strange to me that any kid running ab can alone kill a webserver just by setting the concurrent connections to the servers MaxClients.

  • Endian Destination NAT

    - by Ben Swinburne
    I have installed Endian Community Firewall 2.3 and am clearly misunderstanding/doing something wrong with it. I'm trying to create some destination NAT rules to allow incoming connections to various services within the network. Router - RED I/F - x.x.x.x Router - GREEN I/F - 192.168.11.253 ECF - RED I/F - 192.168.11.254/24 ECF - GREEN I/F - 192.168.12.254/24 Target server - 192.168.12.1 Please ignore the haphazard choice of subnets and addresses- I'm trying to quickly plop Endian into an existing network before a complete rework in 6-12 months so for now. Everything works except destination NAT, so outgoing connections are fine, the routes between the two subnets are OK etc. I want to create various incoming NATs but let's take for the sake of argument, SMTP port 25 from the Internet to Target server 192.168.12.1. I've tried almost every combination of options in the Destination NAT section to achieve this and clearly am doing something wrong. I suspect my confusion must be somewhere in the Access From and/or Target section. The rest seems OK Filter Policy = Allow Service = SMTP Protocol = TCP Port = 25 Translate to type = IP DNAT Policy = NAT Insert IP = 192.168.12.1 Port Range = 25 Enabled = Checked Position = First I can't work out what I'm doing wrong, or am I doing it right and it's just not working!? Any help would be greatly appreciated.

  • Linux Kernel Packet Forwarding Performance

    - by Bob Somers
    I've been using a Linux box as a router for some time now. Nothing too fancy, just enabling forwarding in the kernel, turning on masquerading, and setting up iptables to poke a few holes in the firewall. Recently a friend of mine pointed out a performance problem. Single TCP connections seem to experience very poor performance. You have to open multiple parallel TCP connections to get decent speed. For example, I have a 10 Mbit internet connection. When I download a file from a known-fast source using something like the DownThemAll! extension for Firefox (which opens multiple parallel TCP connections) I can get it to max out my downstream bandwidth at around 1 MB/s. However, when I download the same file using the built-in download manager in Firefox (uses only a single TCP connection) it starts fast and the speed tanks until it tops out around 100 KB/s to 350 KB/s. I've checked the internal network and it doesn't seem to have any problems. Everything goes through a 100 Mbit switch. I've also run iperf both internally (from the router to my desktop) and externally (from my desktop to a Linux box I own out on the net) and haven't seen any problems. It tops out around 1 MB/s like it should. Speedtest.net also reports 10 Mbits speeds. The load on the Linux machine is around 0.00, 0.00, 0.00 all the time, and it's got plenty of free RAM. It's an older laptop with a Pentium M 1.6 GHz processor and 1 GB of RAM. The internal network is connected to the built in Intel NIC and the cable modem is connected to a Netgear FA511 32-bit PCMCIA network card. I think the problem is with the packet forwarding in the router, but I honestly am not sure where the problem could be. Is there anything that would substantially slow down a single TCP stream?

  • Vista ICS issue

    - by Bill Grey
    I have a strange problem with Internet Connection Sharing on a laptop running Vista Business. This laptop is connected to the internet via the ethernet port, which goes to an ADSL modem. it is automatically assigned the IP address 192.168.1.50, and the modem/gateway is 192.168.1.1 My friends laptop is running Vista Home. Previously, I would create an ad hoc wireless network, enable ICS, and everything would be perfect. My friend would have internet access via this. However, something has now mysteriously broken. If I enable ICS on the wireless connection, it resets my Local Area Connection, assigning it the manual IP address of 192.168.0.1, which means my connection to the internet is destroyed. Both wireless adapters on each network are assigned auto configuration addresses, in the 168. range. They can see each other fine, but my friends laptop cannot access the internet via mine, even after I have restored the Local Area Connection settings. I understand the computer with ICS enabled must have the IP of 192.168.0.1, but previously, before whatever went wrong, my wireless adapter would be 192.168.0.1 and my friends computer would get an IP via DHCP. I have also tried setting static IP address and making a bridge, none of which works. How can I fix this problem, and prevent enabling ICS from touching my Local Area Connection? Both machines have no firewall, have appropriate settings etc...

  • Virutal Machine loses network connectivity on Hyper V Cluster

    - by Chris W
    We're running a number of VMs on a 6 node failover cluster of blades using Hyper V. We have an intermittent issue (every few days at different times - not a fixed frequency) of VMs losing network connectivity. Console access to the VM suggests all is fine and the underlying blade has normal connectivity. To resolve the problem we either have to re-start the VM or, more usually, we do a live migration to another blade which fires up connectivity and we then migrate it back to the original blade. I've had 3 instances of this happen with a specific VM running on a particular blade however it has happened once with a different VM running on a different blade. All VMs and blades have the same basic setup and are running Windows 2008 R2. Any ideas where I should be looking to diagnose the possible causes of this problem as the event logs provide no help? Edit: I've checked that each blade is running the latest NIC drivers and all seem to be fine. Something that is confusing me - a failover or restart of the VM resolves the issue. Whilst I need to work out the underlying issue that is causing the NICs to hang I'm also concerned that the VM didn't failover to another node which would have solved the outage for me. Is there a way to configure the cluster so that it can tell that the VM guest has lost connectivity and fail it over? As things stand the cluster is assuming that the VM is running happily as I presume Hyper V says everything is great even though there is a problem.

    I'm not sure what part of my system is responsible for this, but when using PowerPoint, I have problems when trying to resize drawing objects. I'll be dragging the handle and suddenly, the object will deselect and whatever is behind the object will select and start moving around. Next thing I know, the keyboard won't type anymore, and the only way to fix it is to unplug the USB and plug it back in. In case it's hardware related, I'm using an IMB Thinkpad T60P in a docking station. My keyboard is a Microsoft Natural Keyboard Pro. My OS is Windows XP SP3. I've never noticed this happening in anything besides PowerPoint, and I don't know anyone else who has this problem (even people with similar setups). Any ideas what it could be? Edit Well, it looks like I only get the problem if I plug the mouse into my docking station's USB. If I plug directly into the laptop's USB, everything works fine. And, again, this problem is only with PowerPoint. I tried playing with some drawing objects in Word and had no issue no matter where my mouse was plugged in. I should also mention I tried a different mouse (a standard Microsoft corded mouse instead of my Logitech trackball), but that made no difference. So, I don't think it's anything specific with the trackball or the trackball's driver. I tried searching Google but came up empty, so I'm guessing this problem is something unique to my setup. If you have any thoughts or ideas to try, I'd love to hear them.

  • likewise-open and samba as pdc

    - by Knight Samar
    Hi, We have successfully implemented a Samba Primary Domain Controller for a hybrid Windows-Linux environment. So now I am setting up dual-boot clients with Windows XP and Ubuntu 9.10. Windows XP can be easily added to the Samba Domain. Everything is manageable. No worries. But when I try using likewise-open 4.1 to add the Ubuntu 9.10 to the samba domain, it cannot locate the domain controller. domainjoin-cli --loglevel verbose join MYDOMAIN root Error: Unable to resolve DC name [code 0x00080026] Resolving 'MYDOMAIN' failed. Check that the domain name is correctly entered. Also check that your DNS server is reachable, and that your system is configured to use DNS in nsswitch. I even tried mydomain.com variations but to no avail. What am I missing ? I read up a document on MSDN wherein it says that the Domain Controller creates some SRV records in the DNS server. I guess, I don't have them on my BIND. Do you think that is the problem ? If yes, can anyone please point out how and what SRV records need to be added. Thanks.

  • How to get the permissions right for /dev/raw1394

    - by Mark0978
    I recently upgraded one of my ubuntu machines to Karmic and I'm having trouble getting the permissions of /dev/raw1394 set to 0666. They only thing this machine is used for is recording audio from a firepod which uses /dev/raw1394 via jackd and there are no other FireWire devices connected, so security around this device is not really an issue. If I run as root, everything works as expected, but I have some folks that run the recorder that I don't want to have root access. However, I can't figure out which lines setup the perms I've tied this: /etc/udev/permissions.d/raw1394.rules:raw1394:root:root:0666 And I have this setup (default install) /lib/udev/rules.d/75-persistent-net-generator.rules:SUBSYSTEMS=="ieee1394", ENV{COMMENT}="Firewire device $attr{host_id})" /lib/udev/rules.d/75-cd-aliases-generator.rules:# the "path" of usb/ieee1394 devices changes frequently, use "id" /lib/udev/rules.d/75-cd-aliases-generator.rules:ACTION=="add", SUBSYSTEM=="block", SUBSYSTEMS=="usb|ieee1394", ENV{ID_CDROM}=="?*", ENV{GENERATED}!="?*", \ /lib/udev/rules.d/60-persistent-storage-tape.rules:KERNEL=="st*[0-9]|nst*[0-9]", ATTRS{ieee1394_id}=="?*", ENV{ID_SERIAL}="$attr{ieee1394_id}", ENV{ID_BUS}="ieee1394" /lib/udev/rules.d/50-udev-default.rules:# FireWire (deprecated dv1394 and video1394 drivers) /lib/udev/rules.d/50-udev-default.rules:KERNEL=="dv1394-[0-9]*", NAME="dv1394/%n", GROUP="video" /lib/udev/rules.d/50-udev-default.rules:KERNEL=="video1394-[0-9]*", NAME="video1394/%n", GROUP="video" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[!0-9]|sr*", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}" /lib/udev/rules.d/60-persistent-storage.rules:KERNEL=="sd*[0-9]", ATTRS{ieee1394_id}=="?*", SYMLINK+="disk/by-id/ieee1394-$attr{ieee1394_id}-part%n" And I find these lines in /var/log/syslog Apr 30 09:11:30 record kernel: [ 3.284010] ieee1394: Node added: ID:BUS[0-00:1023] GUID[000a9200c7062266] Apr 30 09:11:30 record kernel: [ 3.284195] ieee1394: Host added: ID:BUS[0-01:1023] GUID[00d0035600a97b9f] Apr 30 09:11:30 record kernel: [ 18.372791] ieee1394: raw1394: /dev/raw1394 device initialized What I can't figure out, is which line actually creates that raw1394 device in the first place. How do you get /dev/raw1394 to have permissions 0666?

  • Issues with creating USB bootable Mountain Lion

    - by Sidd
    I am trying to set up a triple boot Windows 8, Mountain Lion, and Ubuntu. I am stuck though. I have got Windows 8 on a partition, and I am trying to get Mountain Lion on there at this point. I installed a VMware with a Snow Leopard 10.6.2 image on the Windows 8 platform. I used the disk utility in this program in order to get Mountain Lion on there. This is what i did specifically: I got the installesd.dmg. I 'mounted' that file or whatever you call it, and out came something along the lines of "Install Mountain Lion OS x" (something like that - it was like a submenu under the installesd.dmg in the disk utility). I got my PNY 8 gb Attache Flash Drive and went to the Erase tab of disk utility. I erased it using the Mac OS Extended (Journaled) setting and called it "Mac". I went to the Restore tab, dragged "Mac" into destination, and dragged "Install Mountain Lion OS x" to the source. Everything seemed to go well, but it didn't. When trying to boot from the flash drive (and yes, I set the BIOS correctly), it skipped it, and loaded Windows 8 normally as if nothing was plugged in. When I try looking at the flash drive in windows 8, it comes up as a 200 mb capacity drive labeled "EFI" with nothing in it (remember, it was 8gb in the beginning). I downloaded Plop Boot Manager, but it did not recognize a USB being plugged in. Does anyone know how I could fix this?

  • Server and Network Lag

    - by DanSpd
    At my home I have a server and my computer. Server has Windows Server 2008 Standart 64 bit installed and then my computer has Windows 7 64 bit installed. My home router is DIR-615 My server has a game server installed on it and basically total open connections on server are around 700. Once its around 700 server and then whole home network lags really badly. My internet connection is good and only around 600kb/s is being used out of 2mb/s (real download/upload speeds). So far I assume that my router has a connection limit and with server + my computer connections it peaks at around 1k and lags everything. Another assumption server lag comes from connection limit. On the internet I have read that standart version of server has connection limit of 700 + 10 reserved. I do not rmember where I found that information but it was on microsoft website. So I have two options. First is to upgrade my router to Netgear FVS318G-100 and second is to change connections limit on server. Any advices? Thank you
