• Can't find partition tab in disk utility osX ver. 10.6.8

  - by John W

  I just got a used Mac Book Pro. I created a new admin account and deleted the old one as well as one other user. This is an older late 2007 MBP... the osX upgrade to 10.6.8 was just performed. My Macintosh HD is showing up as Partition 2. I ran disk utility (not from install disk), but there was no partition tab. I have a 160GB drive with only 53GB of space left on it. Since I am the only user and have no files on the laptop yet, I don't understand why there is so little space left. Surely the OS can't use up over 100GB. I wanted to run disk utility to see if there were any recovery partitions or other partition left over from the previous owner that could be erased to make room for expanding the main partition. Unfortunately, there is no partition tab in disk utility. The documentation I have found on line states that this version of osX includes that utility. The osX disks I have are for an older version so I wasn't sure if they would be of any use in solving this problem. Also, I was afraid if using the disks, would I lose the little bit of data/apps that I have assembled. I would rather not do a fresh install and have to do all the updates again to achieve this. The previous owner had some apps that I don't want to lose as I would have to pay handsomely to get them back. Simply, if all the previous users data is backed up on here after deleting user is still taking up space on a recovery partition (that I can't see)... I need to locate it erase it and expand the primary partition to re-aquire disk space for my files. I am new to Mac, so please be as descriptive as possible. Thanks.

• Windows Server 2012 licensing issue preventing RDP connections?

  - by QF_Developer

  I am witnessing an unusual behaviour on 1 of 5 Windows Server 2012 R2 machines (clean install) that is preventing any remote connections from being established via RDP. I have run through the prerequisites for RDP here but I am finding that any remote connection attempt instantly stops the "Windows Protection Service". When I check the event logs I see the following entry. The Software Protection Service has stopped Event ID: 903 Source: Security-SPP From what I have read Security-SPP is tasked with enforcing activation and licensing, it appears that RDP requires this service to be in the running state. Is it possible that I have inadvertently activated this instance of Windows with a key that has already been associated to another instance (We have 5 keys as part of an MSDN subscription)? Would this be sufficient to block RDP access? When I look under System Properties (Windows Activation) it states that Windows is activated and there are no other obvious indicators that there's a licensing issue. EDIT 1: I ran a Powershell script to display the product keys for all servers in order to check for any duplication. For the problematic server I am getting the message The RPC server is unavailable.

• Cisco Call Manager adding 7945's

  - by Will

  Hello we currently have a call manager settup (older we are working on upgrading it) but for now we are looking to add 7945 IP phones. We currently have 7960's all over the place, but we can't get these new anymore. Here is the info about our call manager ace.dll 5.2.5.0 CCM4.1(3) aced.dll CCM4.1(3) AdministrativeReportingTool.exe 4.1(0.45) 4.1(3)sr4d Apache Tomcat 4.1 CCM4.1(3) ASTIsapi.dll 3.3.2.0 4.1(3)sr4d AudioTranslator.exe 4.0.0.3 CCM4.1(3) Aupair.exe 4.1.3.10472 4.1(3)sr4d AupairChangeNotify.dll 4.1.0.11 CCM4.1(3) AuthFilt.dll 4.0.0.0 4.1(3)sr4d AVVIDCustomerDirectoryConfigurationPlugin.exe 4.1.0.17(0) CCM4.1(3) bootp.exe 2.0.2.2 CCM4.1(3) BulkAdministrationTool.exe 5.1(4c) 4.1(3)sr4d CallBackService.exe 3.3.2.3 4.1(3)sr4d ccm.exe 4.1.3.17472 4.1(3)sr4d CcmPerfMon.dll 4.1(3)sr4d CCNTEST.EXE CCM4.1(3) cdpintf.dll 4.0.0.0 CCM4.1(3) Cisco CallManager 4.1(3)sr4d 4.1(3)sr4d One of the admins recommenced downloading a device pack, which we did. However when we ran it on the call manager server it gave the error "unable to read script" Any recommendations on how to get these phones working with our Call Manager? Thank you.

• Upgrading PHP, MySQL old-passwords issue

  - by Rushyo

  I've inherited a Windows 2k3 server running an XAMPP-installation from the stone age. I needed to upgrade PHP to facilitate an upgrade to MediaWiki to facilitate a new MediaWiki extension (to facilitate some documentation to facilitate doing my job to facilitate getting paid to facilit... you get the idea). However... installing a new version of PHP resulted in PHP's MySQL libraries refusing to communicate using MySQL's 'old style' 152-bit passwords. Not a problem in theory. The MySQL installation is post-4.1, so it should have the functionality to upgrade the user's passwords from 152-bit to 328-bit (what a weird hashing algorithm...). I ran the following: SET PASSWORD = PASSWORD('foo'); on MySQL but querying: SELECT user, password FROM mysql.user; returned just the same password I started out with - 152-bit. Now... I suspect you're thinking 'AHA! old-passwords is on!'. Unfortunately it's not - I've disabled it in the configuration (explicitly set it to 0), made doubly sure I have an absolute reference to that configuration file and ensured the service isn't using the --old-passwords flag. The service was reset after each and every operation. So I went onto another system and generated the 328-bit hash on there, copying the hash over to the first MySQL instance. Unfortunately, that didn't work either (I did remember to FLUSH PRIVILEGES). The application error is: "'mysqlnd cannot connect to MySQL 4.1+ using the old insecure authentication. Please use an administration tool [...snip...] Is there anything else I can try to get PHP to recognise MySQL as not using the 'old insecure authentication'? MySQL seems to be stuck in 'old-passwords' mode and I can't get it out of it.

• Access to CD/DVD Drive is Denied through Windows 7 Explorer (Permission Problem)

  - by Synetech inc.

  A while ago I started having trouble with my optical drives. Both of them keep showing up in Explorer as CD/DVD drives on boot, but as soon as I put a disc in either one, it suddenly turns into a hard-drive—“local disk” is displayed in the Type column, though the File System column remains UDF/CDFS. (I though that maybe it was a permission issue on the registry key in HKLM\System\CurrentControlSet..., but I’m not so certain because of the next test.) When I try to open a disc (of any type), I get an access denied error message. If I open an elevated command-prompt, I am able to access the files. Also, if I kill Explorer and run it from an elevated command-prompt (thus giving Explorer elevated permissions), then I can access the files from Explorer. I’ve tried uninstalling and reinstalling the devices without success. The security dialog indicates that there are none set for the drives (no owner and no permissions). I tried setting the owner, but am only able to do so if there is a disc in it (it complains if it is empty), but the settings do not stick (if I immediately open the security dialog after setting it, it is empty again). I tried setting permissions, but that gives an error. I’ve included a screencap-flowchart of the security dialog of one of the drives below. (Yes, I made sure that there are no upper- or lower-filters, and yes, I ran sfc. I also made sure that in the policy editor, “devices: restrict CD-ROM...” is not set.) Does anyone know what the owner and permissions are supposed to be for optical drives and how to reset them?

• Deploying multiple identical copies of a virtual machine for compute tasks

  - by Reid

  I have a compute task which has a large number of library dependencies. I would like to deploy it on some of my company's large Linux clusters, where I do not have root. I could probably track down, compile, and install the right versions of all the libraries, but this looks to be quite tedious and would have to be repeated if I deployed it again somewhere else. On the other hand, it's pretty easy to install on current Ubuntu. This led me to wonder about a virtual machine approach. Could I put together a virtual machine which booted up, ran the computation (with parameters from and results to the host), and then shut down? In other words, I'd like a command like this that I could run on the host: $ ./run-vm --ram N --task /path/on/host/foo.sh --results /another/host/dir/ This would boot the VM, run foo.sh, and put the (relatively small) results of the computation in /another/host/dir/. It's important to start up many instances of the VM simultaneously, both on a single node and multiple nodes of the cluster. So it would be nice if I didn't have to make many copies of the VM virtual disk and metadata. As the task instances are completely independent, the VMs would not need any network support once deployed, or any outside communications beyond reading and writing the host filesystem. Is this possible, and if so, how might I go about doing it? Are there assumptions I've made above which are bogus?

• Western Digital My Book not recognized by WD software

  - by Kari

  A few years ago I bought a WD My Book Pro 2. It worked fine for a while, then one of the drives failed and I sent it back to be replaced under warranty. I never got around to setting up the new one when I got it back. I finally ran out of room on my internal drive, so I tried to use the external - no go. Both drives spin up, but aren't recognized by either Disk Utility (Mac) or the WD Drive Manager. I tried on a PC as well with fresh software. Then I pulled the drives out of the enclosure (warranty is already expired) and plugged them straight into the PC. Both recognized and working 100% in RAID0. BIOS recognizes either disk as functional; Windows only sees them when both are connected due to the RAID which I can't change without the WD software. The drives that were returned to me are the "Green" drives which I've read are NOT recommended for RAID. Is it possible that this is interfering with them reading externally? Any other ideas? My main computer is a laptop so using them internally isn't an option :(

• Certain websites redirect to 127.0.0.1. How do I fix this?

• Rescue system running TFS that BSODs, into vmware esxi

  - by 3molo

  Hi, After moving to new facilities, one of our old Dell servers running Windows Server 2003 R2 on PowerEdge 2650 HW BSODs with 0x8e. The server runs Team Foundation Server, so we have a few guys dependent on it. No one here knows TFS, so we have no idea how difficult it would be to setup from scratch. We have the MSSQL database(s) backed up, recent and fresh copy. Tried removing/refitting memory modules, but with no success. The system boots into safe mode but hangs occasionally. I booted a linux livecd and did a dd of both c: and d:, so I have all the data in compressed images on a vmware machine. For the guest, I created a 38G (actually it became 40GB) partition to act as C:, and booted a live cd. I then uncompressed the compressed disk image of c: and dd'd it to the new c: using 'gunzip -dc c.img.gz | dd of=/dev/sda1 bs=1M'. The operation ran for about 1000 seconds, and completed successfully. I assumed it would at least try to boot windows (but most likely BSOD due to not having correct drivers), but the Vmware ESXi guest does not seem to recognize it as a bootable disk. We don't have the vmware enterprise license, so the vmware converter cold cloning is not an option. Did I do something wrong in my dd's etc with the ISOs, or why would it not (try to) boot? Am I wasting my time? What other approach is there? Will continue to try to remove services and drivers to make the physical machine at least work reasonably well in safe mode. What do you suggest? 1. Continue to get the dd'd images to the virtual disk and get it to boot. 2. Install a new windows server, get team foundation server and restore from backup. 3. Focus on the old problematic hardware Any help appreciated

• Why does my simple Raid 1 backup storage perform really slow sometimes?

  - by randomguy

  I bought 2x Samsung F3 EcoGreen 2TB hard disks to make a backup storage. I put them in Raid 1 (mirror) mode. Made a single partition and formatted it to NTFS, running Windows 7. For some reason, accessing the drive's contents (simply by navigating folders) is sometimes really slow. Like opening D:/photos/ can sometimes take several seconds before it starts showing any of the folder's contents. Same applies for other folders. What could be causing this and what could I do to improve the performance? I remember that there was an option somewhere inside Windows to choose fast access but less reliable persistence operations (read/write). It was a tick inside some dialog. At the time, it felt like a good idea to take the tick away from the option and get more reliable persistence but slower access, but now I'm regretting. I'm unable to find this dialog.. I've looked hard. I don't know, if it would make any difference. Oh, and I've ran scan disk and defrag on the drive. No errors and speed isn't improved.

• Chrome Lockups Windows 7 64-bit

  - by Mike Chess

  I'm running Google Chrome (6.0.427.0 dev) on Windows 7 Home Premium 64-bit (AMD Phenom 3.00 GHz, 8 GB RAM). The computer lockups hard after running Chrome for about five minutes. The lockup happens whether Chrome is actually being used to browse web sites or it is just idling. No programs can be started or interacted with when this happens. The computer must be power-cycled to recover. The lockup happens regardless of which web sites are being browsed. The system event logs do not show any events around the time when the lockup transpired. All other applications run just fine on this system. In fact, Chrome ran without issue for several months on this system (the system was brand new 03-2010). I also run the same version of Chrome on other computers (Windows XP SP3) without issue. I've come to really like Chrome and use it as my default browser whenever possible. What could be causing Chrome to cause the system to lockup as it does? Does Chrome have any logs that aren't part of the Windows event log? Does Chrome have a debug command line switch that might reveal more about what happens?

• KVM virtual machine unable to access internet

  - by peachykeen

  I have KVM set up to run a virtual machine (Windows Home Server 2011 acting as a build agent) on a dedicated server (CentOS 6.3). Recently, I ran updates on the host, and the virtual machine is now unable to connect to the internet. The virtual network is running through NAT, the host has an interface (eth0:0) set up with a static IP (virt-manager shows the network and its IP correctly), and all connections to that IP should be sent to the guest. The host and guest can ping one another, but the guest cannot ping anything above the host, nor can I ping the guest from anywhere else (I can ping the host). Results from the guest to another server under my control and from an external system to the guest both return "Destination port unreachable". Running tcpdump on the host and destination shows the host replying to the ping, but the destination never sees it (it doesn't even look like the host is bothering to send it on at all, which leads me to suspect iptables). The ping output matches that, listing replies from 192.168.100.1. The guest can resolve DNS, however, which I find rather odd. The guest's network settings (connection TCP/IPv4 properties) are set up with a static local IP (192.168.100.128), mask of 255.255.255.0, and gateway and DNS at 192.168.100.1. When originally setting up the vm/net, I had set up some iptables rules to enable bridging, but after my hosting company complained about the bridge, I set up a new virtual net using NAT and believe I removed all the rules. The VM's network was working perfectly fine for the last few months, until yesterday. I haven't heard anything from the hosting company, didn't change anything on the guest, so as far as I know, nothing else has changed (unfortunately the list of packages updated has since fallen off scrollback and I didn't note it down).

• Can I restore one of my user's profiles in Vista?

  - by Rod

  My youngest daughter uses my 4 year old laptop, which has Windows Vista installed. Somehow she got some Trojan (Vista Internet Security). (I'd love to know how that happened, seeing as how she is a standard user, and I have VIPRE as my AV.) Anyway, I ran a deep anti-virus scan using VIPRE, which identified it. I decided to delete everything that it identified. Now she cannot use anything in her profile. If she tries to bring up the browser, it recycles over and over again a dialog box asking which program to use. If I try to run any program at all, it doesn't know what to do. For example, it is totally lost trying to run the command line. If I bring up Windows Explorer and navigate to Windows\System32 and try to run the command line, or anything at all from there, it goes "Huh?" What in heck has happened?? Is it possible to fix this, and if so, how? As an aside, I can log into my account (my account on that machine is an administrator) and it works fine.

• MySQL stops accepting connections over 3306, still working on localhost

  - by Ben Dilts

  I have a MySQL database that stopped accepting connections from my web server altogether. So I SSH'ed into the server and started checking its vitals. The hard disks had plenty of open space, and there was plenty of available memory and swap space. Nothing was eating up the CPU (close to 100% idle). I even connected to MySQL locally and ran a few queries without any issues. But SHOW PROCESSLIST only showed my own connection, no others. Worst of all, in the MySQL log, no errors even remotely coincided with the unavailability of the server. On the web server, I got an error saying "Lost connection to MySQL server during query" at the moment the unavailability started, followed by a bunch of "MySQL server has gone away" errors. There's only one other application on the server that accepts network connections, and I killed that one (in case it was holding too many open connections or something), but it didn't help. Finally I just restarted the MySQL process, and everything is (for now) working again. What else should I check in these circumstances? Any idea what the problem might be? And how might I verify that is in fact the problem?

• How to fix high Load_Cycle_Count laptop drive (TOSHIBA MK6006GAH in Vaio TX1XP)?

  - by Sam Brightman

  Hoping someone knows exactly what's going on here. It seems this drive has some combination of aggressive power saving settings and Ubuntu defaults that has massively increased the Load_Cycle_Count for the drive: https://wiki.ubuntu.com/DanielHahler/Bug59695 So the drive is now so slow that it cannot boot because it takes long enough to access the data that the kernel will not recognise it properly. I'm not worried about the data on the drive, but would really like to keep the laptop functioning. There is some indication that this is possible because the figure is still low 200,000s and most drives supposedly go to 600,000. Additionally, SMART tests pass and consider the drive healthy and without errors. But the really surprising thing was when I ran mhdd... Every single read came up red (slow) until I pressed 'R' for reset drive. I noticed the next read was normal speed, so held down 'R'. Magically the drive read perfectly for as long as I held the key BUT resumed slow (and noisy) seeking/reading after releasing. I don't think the source code to mhdd is available, so I'm not exactly sure what this means (besides, I don't know enough low-level HDD stuff either). It seems like the drive should be able to work, but is stuck trying to power save or something. There are no BIOS options on the laptop. Does anyone know how I can stop the drive from doing extremely slow/noisy operations like this? Or is constantly resetting the drive also damanging, and only causing it to work well by luck (i.e. not a suggestion that it's fixable)?

• Library conflict in Mac OS X

  - by Juan Medín

  I was trying to install the ImageMagick library on Mac OS X Snow Leopard, and first I tried port and, after it failed, homebrew. It updated some dependencies and installed ImageMagick without problems. So far so good. The problem came when I ran Apache. I got the following error in the system log: 07/04/11 12:55:15 org.apache.httpd[41841] httpd: Syntax error on line 115 of /private/etc/apache2/httpd.conf: Cannot load /opt/local/apache2/modules/libphp5.so into server: dlopen(/opt/local/apache2/modules/libphp5.so, 10): Library not loaded: /opt/local/lib/libpng12.0.dylib\n Referenced from: /opt/local/apache2/modules/libphp5.so\n Reason: image not found I checked the /opt/local/lib and surprise! I don't have the libpng12.0 but the libpng14.0. So, as far as I can tell, something went wrong installing the ImageMagick library. Now, I can't find a way to rollback to the previous libraries, other than copying them from the backup. Do you know if is there a way to recover the previous state or reinstall Apache? Or is this just a corrupt state and I must reinstall OS X?

• How to diagnose issue between mobo, RAID, and SSD cache drive? [migrated]

  - by goober

  Background This issue is happening on my custom-built desktop. Relevant specs: Motherboard: ASUS P8Z68-V PRO Utilizing Intel RST technology (application that uses unused SSD as cache) Processor: Intel core i7-2600k (not overclocked) HDDs: RAID1 of 2x Seagate Barracuda 1TB (ST31000524AS) (RAID performed via z68 chipset) Machine has run fine for ~1 year with no issues, and has been well-maintained (dust, etc.) What Happened Random Freezing issues -- intermittent Looked at the RST application screen to see that the acceleration cache was listed as "unavailable" -- recommended that I power down and reconnect the drive. Reconnected the drive to no avail. Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software. Now, the freeze happens whenever loading something particularly data-driven (a video, a game, etc.) Steps Attempted Reconnected the drive to no avail. Updated Intel RST software to v. 11.6.0.1030 to see if that made a difference. Attempted to move the drive to another SATA port. Acceleration option disappeared from RST software. Connected the drive as its own volume. Formatted it, ran disk check errors -- all seems fine. Reconnected the drive and selected it again as the cache drive. Now, what happens when there is a freeze: Machine freezes I am unable to perform any command Screen then goes black I hit the reset button During boot, all drives show as "Disabled" and I am told no volume can be found I then hit the reset button (or power off/on) again. Either the next time (or sometimes after repeating this once more), the metadata cache is reconstructed and the system boots fine, showing the SSD as a cache. Question I believe this is an issue with the SSD itself, but how can I be sure since connecting it separately appeared to show no problems? I want to make sure it's not an issue with the motherboard, SATA ports, etc.

• Windows 7 BSOD on boot after windows update

  - by Razor Storm

  After Windows updates today, I restarted my desktop (for the first time in a couple weeks), and on boot up ran into a BSOD: STOP: 0x0000007E (0xFFFFFFFFC0000005, 0xFFFFF8000355AB5A, 0xFFFFF880031CB3A8, 0xFFFFF880031CAC10) I tried system restore, but there was only 1 restore point which was from all the way back in January. I tried it anyway but after 10 minutes of running it said system restore could not be completed. Additional info: I checked my BIOS and it is detecting my rams. CPU is Intel Sandy Bridge i5-2500k overclocked to 4.3GHz. I reclocked it back to stock speeds (3.3 GHz) in case it was causing the issue (I highly doubt that it is). But the problem persists. Running Windows 7. 12 GB of RAM at 1333 MHz OS on 64gb SSD. What is causing this? How should I fix it? Also, if it is caused by windows update, is there a way to undo the update with command prompt? I tried safemode, and the blue screen comes up as well, but I am able to access command prompt.

• Macvlan based interface pings from host but not from namespace

  - by jtlebi

  My setup: Private network vboxnet1 10.0.7.0/24 1 Host, ubuntu desktop 1 VM, ubuntu server (VirtualBox) Adressing layout: HOST: 10.0.7.1 VM: 10.0.7.101 VM MAC NAMESPACE: 10.0.7.102 On the VM, I ran the following commands: ip netns add mac # create a new nmespace ip link add link eth0 mac0 type macvlan # create a new macvlan interface ip link set mac0 netns mac On the mac namespace, inside the VM: ip link set lo up ip link set mac up ip addr add 10.0.7.102/24 dev mac0 So that we basically end up with: (Like Inception ?) +------------------------+ | Host: 10.0.7.1 | | | | +--------------------+ | | | VM: 10.0.7.101 | | | | | | | | +----------------+ | | | | | NS: 10.0.7.102 | | | | | | | | | | | +----------------+ | | | +--------------------+ | +------------------------+ What works: Ping between Host and VM Ping between NS and NS dhclient from NS What does not work: ping between NS and VM ping between NS and Host Where I started to go nuts: tcpdump on host (the real machine) actually shows ARP request AND replies tcpdump on NS shows ARP requests sent to the host tcpdump on VM makes the whole mess work (!) -- ping starts to get answers when tcpdump is started on the VM ?!? So, I bet you were eager for it, my question is: how to I make it work ? I suspect something's wrong with ARP on the macvlan inside the NS but can't figure out what exactly... Btw, I did the same expérimentations with the mac0 interface directly on the VM (no namespace) and it worked flawlessly.

• Onboard Ethernet suddenly stopped working to router

  - by AfterschoolHobbist

  Hey guys, yesterday I have a sudden problem of my Ethernet connection to my router. My computer is a Pendium 4 with Window XP SP3 running on it and it was working fine earlier in the day, but yesterday night was the start of the problem. My computer is unable to ping to the router and to any other website and unable to get internet connection. As beside it was connected to a hub, I directly connected it to the router directly and the same problem occurred, being unable to ping to the router (and connecting to it) and still no internet access. My directly connected to the modem and the problem still persisted. For each connection, I connected it to my computer and my laptop and my laptop was able to connect, while my desktop computer was unable. I wondered if it was a OS issue and ran a live Ubuntu CD to see if Ubuntu was able to connect to the internet, but the issue persisted and I was unable to get internet access. I then set my router's lease time to 1 hour and waited. After 1 hour, the lease for my computer was removed and I hoped this worked, but it didn't work, but something strange is acting up. My desktop computer is still unable to ping to the router or connect to the internet, but for some reason, my router and desktop computer is still able to contact each other by providing a lease of an local ip address. The router record of a lease to my desktop computer, and when I do ipconfig, my desktop also recognize that it has been provided a local ip address. I have concluded that this is a hardware issue and the only solution to fix this is to by a network card adapter, but I am wondering if anyone has any solutions that could explain why this happen, why my mac address is 01-23-45-67-89-ab, and is there any way to fix it without buying a new network card? Thanks in advance.

• Suspected Corrupted Windows 7 MBR?

  - by AridDecay

  So, this may not be the correct place to put up my question, but i'll give it a shot. I'm having an issue repairing this computer. It was brought to me with the described issue of 'Not turning on' Later, I found that it would come with the error of 'No boot sector found on internal hard drive.' I assumed it was an MBR issue due to a virus or cutting a Windows update short. I booted into my trusty recovery enviroment and ran bootrec.exe /FIXMBR and restarted -- No luck I started to think (After multiple attempts to get the MBR sorted out, including creating a new boot sector) that the Hard-drive was possibly starting to cave in on itself, so I booted into a linux bootable CD and went to check the SMART data. Odd, say's it's inaccessible. That seems odd to me, considering it's a newer (two years old or so) Windows 7 computer. All new Hard-drives have SMART. So, I checked the BIOS. No mention of SMART anywhere. Greaaaat. I decided as a last-ditch effort to switch the hard-drive type to ATA in the BIOS (God knows why, I was getting frusterated) instead of AHCI. VOILA! It actually attempts to boot, gets halfway through the little windows animation, does an incredibly (Half a second) quick BSOD, and shuts down. Does anyone have ideas on what's going on here? I'm at my wits end.

• iptables rule on INPUT between 2 ethernet cards on the same host

  - by user1495181

  I have 2 eth cards on the same host. Both connected directly with LAN cable. I set eth0 with ip - 192.168.1.2 I set eth1 with ip - 192.168.1.1 I set this rule: iptables -A INPUT -p tcp -j NFQUEUE --queue-num 0 There are no other rules. (I ran iptables -X,-F) I send TCP syn packet ( with c++ program by using raw socket) from 192.168.1.2 to 192.168.1.1 In wireshark i see that the packet received on eth0, but the iptables rule (above) dosnt apply for this packet. when i sent the packet to remote host and apply this rule on the remote host than it work correct. So, i guess that this is due to the fact that both eth cards exists the same host. . I need to create iptables INPUT rule for local eth card (dest and src on the same machine ). I need it for simplify test. Did i guess the problem correct? is there a way to bypass this? Ps - connected them via switch didn't help. the rule wasn't applied. Run on Ubuntu. TCDUMP show the packet: 10:48:42.365002 IP 192.168.1.2.38550 > 192.168.1.1.34298: Flags [S], seq 0, win 5840, length 0 but logging of iptables like this, has nothing: iptables -A INPUT -p tcp -j LOG --log-prefix '*****************' iptables -A OUTPUT -p tcp -j LOG --log-prefix '#################'

• Apache and Virtual Hosts Problem on OS X

  - by Charles Chadwick

  I recently formatted and installed my iMac. I am running 10.6.5. Prior to this format, I had the default Apache web server up and running with several virtual hosts, and everything ran beautifully. After formatting, I set everything back up again, and now Apache is acting funny. Here is a description of what I have going on. My default root directory for the Apache Web server is pointed to an external hard drive. In my httpd.conf, here is what I have: DocumentRoot "/Storage/Sites" Then a few lines beneath that: <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow Allow from all </Directory> And then beneath that: <Directory "/Storage/Sites"> Options Indexes FollowSymLinks MultiViews AllowOverride All Order allow,deny Allow from All </Directory> At the end of this file, I have commented out the user dir include conf file: Include /private/etc/apache2/extra/httpd-userdir.conf And uncommented the virtual hosts conf file: Include /private/etc/apache2/extra/httpd-vhosts.conf Moving on, I have the following entry in my vhosts file: <VirtualHost *:80> DocumentRoot "/Storage/Sites/mysite" ServerName mysite.dev </VirtualHost> I also have a host record in my /etc/hosts file that points mysite.dev to 127.0.0.1 (I also tried using my router IP, 192.168.1.2). The problem I am coming across is, despite having PHP files in /Storage/Sites/mysite, the server is still looking at /Storage/Sites. I know this because in the DocumentRoot contains a php file with phpinfo() (whereas the index.php file in mysite has different code). I have tried setting up other virtual hosts, but they are still doing the same thing. Also, "NameVirtualHost *:80" is in my vhosts file. I saw as a solution on another thread here. Doesn't seem to make a difference. Any ideas on this? Let me know if this is not enough information.

• VNC Server that can be used from command line?

  - by jesusiniesta

  I'm looking for a replacement for a custom vnc server that we have been using in my company for a long time. I need a simple executable that can be run from command line by an IT Support software without the user noticing it (our application will warn the user, we don't want him to see we are using that VNC sever). I need it to support Windows and preferably also OSX. The only option I've found is UltraVNC, but I can't configure it from command line to accept loopback connections without authentication. We have already a whole VNC Viewer + VNC Repeater + Bouncers architecture, and the only missing piece is the VNC Server. Do you know any solution you could suggest me? I'm afraid I'll end up developing a new VNC server myself, may be based on an open source one. EDIT: When I said I don't want the user to notice this VNC server, I should have added that I don't want him even noticing the installation. So better if it can be installed silently or can be executed as a portable executalbe (for instance, ultravnc can be installed and ran as a service from command line, or simply executed quietly, with only a notification icon; its problem is that I can't run it without authentication).
