• Ubuntu PowerEdge T110

  - by Josh

  I just got a Dell PowerEdge T110 server. I moved the boot order to CD - HDD - NIC, then installed Ubuntu 10.10, Desktop Ed. I chose install alongside other OS (even though there was none), then chose use entire partition. It showed that Ubuntu would use 160 of the 160 available GB. It installed, updated (while installing), then said, need to eject and restart, as usual. It restarted, but to a blank screen. No output whatsoever. Not even BIOS. Just blank. The monitor isn't even woken from sleep. Power cycled, still doing it. Tested the monitor with a laptop, and it is fine. What on earth is going on here?

• CentOS 6 - YUM Local Repo - Ensure consistent package distribution

  - by Mike Purcell

  I've read a few guides outlining how to setup a local YUM repo, but none of them explicitly stated an answer to my question; If I set up a local YUM repo, does that mean that any CentOS servers which pull from said repo will never be "ahead" of the local YUM repo? I want to ensure a consistent package distribution across all my servers. Right now, when I do a yum update, even on a daily basis, the servers can be out of alignment. For example if I run YUM update on my dev server in the morning, then run YUM update on one of my production servers in the afternoon, the production server may have picked up a new version of a package that the dev server did not pick up, due to the time window between the update commands. Rather, I'd prefer that I run yum update from my dev server which has access to remote upstream yum repos, then let it sit for 2 weeks, after which I run yum update on my production servers against the local repo on my dev server.

• Vim - dynamic list of open buffers in a window

  - by asfallows

  I've investigated a few ways to maintain a list of open buffers in Vim, and some of them are very good, but none of them seem to behave the way I'd like. It's very possible that nothing like what I want exists, and it can't hurt to ask. I've been using NERDTree in GVim, and I like the idea of putting the information in a slender left-hand window. I've put together a handy diagram for how I'd like my environment to look: |--------|---------------------------------------| | | | | | | |NERDTree| Windows | | | | | | | | | | |--------| | | | | | | | | List | | | of | | | Open | | | Buffers| | | | | | | | |--------|---------------------------------------| So my question is: Is there a vim-native or plugin-enabled way to maintain a list of currently open buffers and select/edit/close from that list, inside a window similar to NERDTree? I understand that this approach may be incongruous with the Vim way of doing things, and if you feel like I'm missing something about how to manage multiple files in a Vim session, please leave a comment with suggestions!

• How much packet loss is normal?

  - by Fabian

  I started monitoring our network using SmokePing. Users occasionally complain about bad network connections, but the problems went away after some minutes usually. I now wanted to get some more quantitative information about those problems. SmokePing regularly pings servers inside our network, in a connected network and outside hosts. I only have a limited amount of control over our internal network and none at all for the connection to the outside and to the second network. I now see quite often (2-4 times a day) that packets to the second network and the outside are dropped. Most of the times it is 1-2 packets out of 20, sometimes more. Inside our internal network no packets are dropped. Is this an expected amount of packet loss, or does it indicate that something is wrong? I'm mainly wondering if I should bother the university IT department about it, or if I should just accept it as it is.

• Laptop connects to other network but not to my home wireless

  - by Nilesh

  My home network's wireless SSID is say "XYZ" I also have an ethernet wire from the same router. I have two laptops A and B Earlier both A and B were able to connect to my home internet through the ethernet and wireless. Suddenly, the laptop B can no longer connect to XYZ or through ethernet. When I do plug the wire, i get the connection icon all green but when I try to access any web page it errors out (page not found) But strangely laptop B connects to my neighbours wireless SSID "ABC". I have also tested laptop B with other networks and it connects fine. Laptop A and many other devices still connect fine with my home wireless "XYZ" Strange thing is when my laptop B connects wireless through XYz, it gets the IP address but then none of the browsers (chrome,firefox, IE) can show any web pages. What settings should I be checking on laptop B that is preventing it to connect to my home internet. Thank you

• How to get Hyper-V to recognize that a VM isn't stopping, it's stopped.

  - by Matt Burke

  I have a Hyper-V virtual machine that has some problems. First, its settings are apparently corrupt: The WMI object contained an invalid value in property BIOSNumLock. The WMI object contained an invalid value in property AutomaticStartupAction. Second, I saw something that implied that I could toggle the NumLock checkbox on the BIOS property page to fix the first problem, but the checkbox didn't show up. So I connected to the VM and shut it down. Now (many hours later) Hyper-V claims that the VM is "Stopping". However, when I follow the interweb's directions on forcing a VM offline (i.e. find vmwp and kill it), I can't find vmwp. The VM's WMI object has a PID that doesn't exist, and none of the vmwp processes have this machine's GUID. So, how do I trick Hyper-V into seeing that the machine is offline (or letting me delete it)?

• Lost "VGA Display" color profile in OS X

  - by Justin Love

  OS X Display settings used to have a color profile named VGA Display, which I found quite usefully for finding color problems before hooking up a projector. Currently, this profile (along with a number of others I've collected from projectors in the past year) is not available. I'm currently OS X 10.6.6 and my best guess is the profiles got wiped out during the last upgrade. None of the available color profiles seem to stink quite enough. Am I overlooking a renamed profile? Is there somewhere I could get a 'VGA Display' profile to install on my computer?

• Disk is apparently in use by the system

  - by Shaun

  I've just fitted two disks to my home server. I'm trying to format and then raid them but I'm getting a problem that hours of Googling hasn't resolved this. The error that I'm getting is: # mkfs.ext3 /dev/sdb1 mke2fs 1.39 (29-May-2006) /dev/sdb1 is apparently in use by the system; will not make a filesystem here! # df -h Filesystem Size Used Avail Use% Mounted on /dev/sda1 4.0G 1.9G 2.0G 49% / none 380M 0 380M 0% /dev/shm /opt/xensource/packages/iso/XenCenter.iso 51M 51M 0 100% /var/xen/xc-install # mount -t ext3 /dev/sdb1 /mnt/b mount: /dev/sdb1 already mounted or /mnt/b busy I'm new to this and it's got me beat. I wouldn't ask if I hadn't done my research first. Thanks.

• How do you change the "scan this dir for additional ini files" path?

  - by amvx

  I managed to get the custom INI to load, but its still loading other .ini files from the default location. I created an fcgi wrapper that passed the ini value as a parameter. That worked. Now just these other ini's need to be loaded from the same dir as my custom ini. The problem is the other .ini files are overriding the settings in my custom php.ini =/ I realize the problem now is that the php.fcgi was compiled with a custom path parameter. So that's a problem. I might have to recompile it using a different location or none at all. I'd hate to have to compile an fcgi for each domain =/

• How can I figure out exactly which process is keeping my Mac from going to sleep and waking it up?

  - by pattern86

  I have read this knowledgebase article, but would like to know if there's a way to tell exactly which process is causing my Mac not to follow the sleep schedule I have set in System Preferences Energy Saver. I have narrowed it down to a being a process and will explain why I think so (see below). I am running OS X (10.6.5) on the new iMac 27" and I am certain it's not the following: The "Wake for Network Access" checkbox in Energy Saver settings (has never been a previous issue) Peripherals (has never been a previous issue) Any active GUI application (all are closed) Additional USB/FireWire drives (none are connected) Bluetooth (it's off) Sharing services (has never been a previous issue) The symptoms are as follows: The computer doesn't go to sleep at the predetermined time. It will wake up some number of hours after being put manually to sleep (but not within the first few seconds/minutes.) Is there a specific string I should be looking for in Console? I have tried searching for "wake" and "sleep" but can't make total sense of the results.

• Thunderbird 3.1.7 file system and file extensions

  - by Sharon Bode

  I have lost all email messages and folders in my Thunderbird program. Where can I look for them? The messages were organized in folders for several years. My system is Windows XP. I have looked in the Thunderbird Profiles default profile folder. I can see Inbox and Trash but none of the other folders I have set up are visible. I cannot directly open Inbox or Trash so I don't know if my lost messages are in these folders. Others in the Community Forum seem to have the same problem but no one has answered them or me. Is there someone in this community who can help? Thank you, Sharon Bode

• Filtering semi-solicited spam

  - by Ketil

  While traditional UCE (get rich quick, enlarge your body parts, Nigerian barristers) are handled adequately, I'm still receiving a lot of not quite unsolicited spam. This is typically from commercial services forwarding "invites" from my "friends" and then "reminding" me of their services. Typical offenders are Facebook, Linkedin, dropbox, bebox, etc etc. (Of course, none of these services provide any way of opting out, except possibly by registering, which they will then take as an invitation to stuff your mailbox with even more crap) What is a good way to deal with these? I can of course junk them using procmail, but is it a better idea to e.g. bounce them, or at least send a reply informing the sender (and "friend") that I am not interested in their service nor their spam. Any solutions to this?

• Huge area of stuck pixels

  - by pixelady

  A toddler slammed down my laptop screen while an iPod was laying on top of the keyboard. The damage resulted in a massive area of stuck pixels on the laptop screen, approximately 2 inches by 10 inches in area. I've tried running various programs that rapidly flick the pixels in different colors, as well as massaging the screen with heat and also without heat. These are the standard methods I read about for fixing a stuck pixel. But none of the online articles I read said how to fix a huge area of pixels, not just single pixels. What else can I try to get the many pixels unstuck? My computer is no longer under warranty and I don't want to buy a new one.

• Why didn't cable select work?

  - by jldugger

  I got roped into doing tech support for a friend of the family. Obviously I'd already failed to hide my powers, ala Penny Arcade. Anyways, the guy bought a DVD burner OEM from Microcenter, and asked me to install it. So I stopped by before and thought I'd be slick and use Cable Select on the jumpers. I didn't get a chance to test it before it I had to leave, and it seems that this didn't work. I came back this week to investigate, and he explains he's confused how none of the software he downloaded was able to burn. So on a whim I switch it to explicit master / slave, and it starts working fine. Whoops. Well, at least it's not the extra crap he found and downloaded for free from the internet. Why doesn't setting both jumpers to Cable Select solve this?

• CentOS VM, NTP synchronization problems

  - by Spirit

  We have three CentOS 5.9 VMs on an ESX3.5 host. Because of the nature of the services we provide it is required that the NTP time is synchronized and the time is correct on all three of them. However one of them constantly drifts back each day for about 66 sec. So far none of us seems to understand as why is this happening. We included the possibility that the VM may be somehow pulling the time from the host, however all of the three VMs have identical configuration settings and they did not have VMware tools installed. Although I realize that this is probably a question of an internal matter and not to ask for on a forum, I would appreciate if anyone of you knows some CentOS NTP diagnostic routines that will help me to diagnose the problem and find a reliable solution. I thank you for the assistance.

• Trying to make changes to the size of the events buffer in prelude-ids auditd plugin

  - by tharris

  I am running systems using the prelude-ids plugin for auditd. When the manager is up every thing works fine however I have a requirement that when the clients can't talk to the manager they should store no more than 250MB of messages, and when they hit that point they should start deleting the oldest events. All I can find is that audispd can be set to an overflow action of ignore,syslog,suspend,single, and halt none of which meet my requirement, and several of which I really cannot use. Does anyone know a way to do this? I know the events get stored in /var/spool/prelude/auditd/global, but I can't find anything about configuring how things are stored here. There are usually several files in the global directory but only 2 of them ever go above 0 in size, data0 and data0.journal.

• Changing the passphrase of a private key in Windows

  - by janos

  I have a private key in Windows, created by puttygen.exe. I used default options to save it, the tool automatically gave it a .ppk extension, and it looks like this: PuTTY-User-Key-File-2: ssh-rsa Encryption: none Comment: rsa-key-20130627 Public-Lines: 4 AAAAB3NzaC1yc2EAAAABJQAAAIBnvvAhyMs4rdlQd4OdajDw4jIPi6vIjrWjt4l4 5C3wHOSxyQQdtSA8XT3K0rSBnNtZRJTb5mfix67qQe3pHCTMSNsYIaBi8xQJHZRa RxdY+1VtGnSlEma8KO2We9eDNCGiwrRTUzqvTiGCnzU0pF1MXxu3ObISJcpqv+sQ 1GB0cw== Private-Lines: 8 AAAA.......... Private-MAC: XXXXXXXXX Now I need to change the passphrase, and reading from the docs it seemed simple enough: puttygen.exe -P key.ppk But this pops up a window with this error: PuTTYgen Error: Couldn't load private key (unable to open file) I also tried to change the passphrase using ssh-keygen that comes with Git Bash: ssh-keygen.exe -p -f key.ppk It asks for my old passphrase, but then it gives me the error Bad passphrase. Which is not true, because I can add the key in pageant.exe, and I am not mistyping the passphrase... Anything else I can try to change or drop the passphrase?

• 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!

• Windows won't ctrl+c and ctrl+v

  - by Thomasstuck

  Using Ctrl+C and V I am unable to copy or paste anything. I have tried many different applications and still no luck. I am able to copy/paste via the shortcut menu when you right click the mouse. Ctrl+F works which means the Ctrl button is functional. I've tried restoring to an earlier restore point. I also ran SFC /SCANNOW (System File Checker) which did not find any errors. Ctrl+C and then right click and paste doesn't work either. I have tried with external and internal keyboard and still no luck. I've clicked on all the relevant search results from Google but none of them work for me. Does anyone know what may be causing this issue and how I can correct it? This problem comes and goes at random times.

• Server 2003 RAS Server Utilising High WAN Traffic

  - by Joe Sergeant

  We have Routing and Remote Access configured on Server 2003 (also our primary domain controller), allowing users to connect in remotely to access files, email, etc. With one user, the RAS Server is constantly sending data to that user's remote computer. From 9am this morning it has transferred almost 800MB. The user isn't transferring any files remotely, certainly not enough to total 800MB anyway. None of the other remote users have had this issue. We have ensured that the user in question has "Use default gateway on remote network" disabled for both IPv4 and IPv6 and we are fairly confident that Offline Files isn't trying to synchronise with the server remotely, too. My question is two-fold. Firstly, has anyone had a similar experience? Secondly, what would be the best software to discover exactly what data is being sent to the remote user?

• What Commands Does Windows Startup Repair Run?

  - by user138284

  Background: I created a wim image that we are planning to deploy to some of our computers, but when I image a computer with it from a flash drive it continually reports that the BOOTMGR is missing (and no, it's not booting off the flash drive). I am able to resolve this by running Windows Startup Repair, but I would rather just add whatever command is resolving the issue to a script that runs after the image. I have already tried running fixmbr, fixboot, rebuildbcd, and nt60, but none of those resolve the issue. Basically, I would like to know what exactly is being done when I run Windows Startup Repair.

• Can't ping other machines in my network

  - by judahgabriel

  I've got 3 machines on my network, all running Windows 7. None of them can ping each other, can't see each other on the network, can't see shares, can't remote desktop, can't see any homegroups. They are all on the same workgroup. They are all connected to the same wireless, WPA2 secured network. They all worked together nicely until I added a password to my wireless network. After that, and after reconnecting all the machines to the password-protected network, they can't see each other. Any ideas what could be wrong?

• Migrating Printers from XP to 7 (using USMT 4.0)

  - by Luís Mendes

  I'm attempting to migrate a user from an XP machine to a 7 machine, using USMT 4.0 (User State Migration Tool, from Microsoft). For some reason the migration of printers isn't working, and none of the topics at Microsoft's TechNet are helping me out. I'll list the topics, just for the record: http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/ab8d6d70-9d1b-419c-8149-37387d4eba6d http://social.technet.microsoft.com/Forums/en-US/w7itproinstall/thread/e92d9ce9-ad9f-4ba0-b326-c7ae6dc50a58 There was a suggestion to use a customized XML configuration file, to force the migration printers, but it didn't work as well. They also mention a folder named DIManifests, which has to be present in the USMT directory. I've tried everything, but with no success. Can anyone please help me sort this one out? Apparently it's a bug, but there's gotta be some workaround. Thank you!
