• Display issue with fresh install of windows server 2012

  - by Tony

  I installed windows server 2012 last night on my home "server". I use server loosely. From the get go I had display and graphic issues. The image was fuzzy and jumbled up during the install. This continued once booted into the install. I did installed Server 2012 twice now as the first time, I only installed "core". I know this is not a busted graphics card because it worked fine in Win7, during boot, and fine in "core" mode. Once booted into "GUI" install of Server 2012, the image was messed up again. To make things even more weird, the windows "loading" screen looks fine. Once the login screen appears the image is fuzzy and jumbled. My guess was that it was a driver issue. I did try to install the win8 x64 drivers from nvidia. This caused the system to become unbootable and I had to restore to a previous working point and uninstall the driver. I did try two different monitors and cables. Also both ports on the back of the video card. I did manage to get RDP running and that works fine. I rarely work directly on this machine but it would be nice to have the option back. Geforce 210, AMD 4600+, 4 gigs of ram.

• Effects of internet connection speeds on server queries

  - by SephMerah

  Can my internet connection significantly effect queries run on phpmyadmin? I am currently 18 down and 30 up. I switched internet connections today and noticed a deep drop in query performance. The query that I am running is SELECT * FROM table. Simple. The table has one row of data. The MySQL server is on the same server as everything else. It is a VPS. Godaddy hosts. I dont have any other information. Centos 6.3 MySQL 5.1 PhpMyAdmin 3.4 Okay used google tools to inspect the XHR going out and coming in and this is what it reported. {"success":true,"message":"<div class=\"success\">Your SQL query has been executed successfully ( Query took 0.0033 sec )<\/div>","sql_query":"<div id=\"result_query\" align=\"\">\n<div class=\"success\">Your SQL query has been executed successfully ( Query took 0.0033 sec ) SNIP..................."}. So apparently my server is fine. The strange thing is though.. The returned XHR comes back exactly as soon as I execute the query on the page. It comes back within less than a second. Why PhpMyadmin does not report the change immediately. I am going to try a re-install.

• Windows Media Center showing Jerky Video on PC

  - by Kris Erickson

  I had to repave my Windows 7 x64 box last week due to a hard drive crash, and for a while everything was running perfectly but now all videos in Windows Media Center are jerky (the sound is fine, they just seem to skip a ton of frames all the time). This is on the local machine, but the same thing happens when I try to stream to my Xbox. The videos all show fine in VLC and Windows Media Player (however exhibit the same problem in Quicktime). I guess I must have installed something recently (in the process of getting all the apps I usually have running on my PC) that caused this but for the life of me I can't figure it out. I have updated to the latest video driver (and then rolled back to the standard Windows 7 driver), I have rolled back all the other drivers that I have installed (I believe). I have uninstalled all the codec packs (I also run TVersity, so I have the TVersity codec pack installed), and I uninstalled TVersity. Nothing seems to help. I have uninstalled windows media center, and reinstalled it from the Programs and Features. I have basically ran out of things to try to fix this, and am almost thinking about reinstalling Windows again. Any suggestions? Edit Specs on the PC (which I figured was unimportant since everything used to work perfectly): Intel Core 2 CPU 6600 @ 2.4 Ghz Nvidia GTS 8800 Built in realtek-audio soundcard 4GB Ram Codecs which are failing: All that I have tried, but at least Xvid, Mpgv (mpeg2 video from a camera), and Wmv (only kinds that I have ready access to).

• Troubleshooting an overheating CPU

  - by Jeff Fry

  I & my father just recently put together a new PC. Specs below. From the very beginning, on boot it will often complain that the CPU is too hot. If I sit in BIOS and watch the CPU, it'll drop back down from red to blue (<72C), at which point I've tended to just boot into Windows...and haven't had any problems. In fact, I've played a couple hours straight of Skyrim at max settings, and not had any visible issues. That said, I've occasionally walked away & come back to find that it's crashed. Yesterday, it crashed (while idle) twice in 12 hours, which shifted the balance from busy-with-life to nervous-I'm-about-to-melt-something. I just installed Core Temp which is showing my 4 cores fluxuating between 70-98C. I'm guessing at this point that the CPU fan may be incorrectly installed or defective. My first thought is to either (a) add water cooling (which the case supports) and / or (b) replace the CPU fan with an after-market one. That said, I'm very open to suggestions. A note, while I certainly don't want to burn money here, I have a baby coming any day now and am still unpacking from a recent move so if I have a choice between an option that costs money and another that takes a while...I'll happily spend a bit extra. Side question: Should I be nervous to even have this on at this point? Let me know if there's something useful I could add to my report. Otherwise, I'm looking forward to your suggestions! Thanks.

• Win/Bios showing wrong RAM in Gateway Netbook?

  - by Ael

  I've seen similar problems, but this seems slightly unique, maybe... I have a Gateway LT21 netbook, Win7. I've upgraded RAM from 1gb to 2gb. It didn't work. So I updated to the latest Bios 1.25, then it worked. 2gb was recognized in the Bios and in Windows. Every was fine. Now today it seemed slow and, to my surprise, both the Bios and Win show only 1gb. :/ I've run memory diagnostic, no error. I entered bios and hit Exit and Save. Still 1gb. I took out the ram, put it back. Still 1gb. :/ CPU-Z shows 2048mb/2gb of RAM. Further testing: if i put in the old 1gb ram, turn on, then put in the new 2gb ram again, the Bios and Win show 2gb of ram. BUT, once restarted at all (even from Bios) it seems to go back to showing incorrect 1gb ram again. :// (There are very few options in the bios, none appear memory-related.) Any ideas?

• Win7 'locking' process/files/folders?

  - by Dynde

  I've had a fair bit problems with sometimes files/folders/processes being 'locked' by Windows. The weird thing is, it's not like the traditional sense, I think, where tools like UnlockIT and wholockme would work. It seems that just giving it a little often helps - making me think it could either be the HDD, the memory, or something in Windows. A scenario: I go into a folder - don't open anything at all, go back up, cut or drag-move the folder to someplace else, it says "Action can't be completed because the folder or a file in it is open in another program". Waiting sometimes 20 seconds sometimes a little longer, and I can move it. Another scenario is deleting a bunch of files in a folder, and it appears that everything is gone, but then suddenly after a few seconds an .exe file pops back up, and I can't delete it. Waiting a few minutes, then pressing refresh and it's gone. I have the strangest feeling that there's a problem with either HDD or memory. I already tried disabling Windows indexing service with no luck. Does anyone have any ideas? EDIT: I should say, that I have a very fast system, 16 GB DDR3 RAM, i7-2600k CPU, SSD main HDD, so I really should not be experiencing any sort of problems, where one might say that it's "reasonable" for the system not to respond right away. Edit2: And I updated SSD firmware a couple months ago, so it shouldn't be bad release FW either

• Rebuilding LVM after RAID recovery

  - by Xiong Chiamiov

  I have 4 disks RAID-5ed to create md0, and another 4 disks RAID-5ed to create md1. These are then combined via LVM to create one partition. There was a power outage while I was gone, and when I got back, it looked like one of the disks in md1 was out of sync - mdadm kept claiming that it only could find 3 of the 4 drives. The only thing I could do to get anything to happen was to use mdadm --create on those four disks, then let it rebuild the array. This seemed like a bad idea to me, but none of the stuff I had was critical (although it'd take a while to get it all back), and a thread somewhere claimed that this would fix things. If this trashed all of my data, then I suppose you can stop reading and just tell me that. After waiting four hours for the array to rebuild, md1 looked fine (I guess), but the lvm was complaining about not being able to find a device with the correct UUID, presumably because md1 changed UUIDs. I used the pvcreate and vgcfgrestore commands as documented here. Attempting to run an lvchange -a y on it, however, gives me a resume ioctl failed message. Is there any hope for me to recover my data, or have I completely mucked it up?

• Cannot open root device xvda1 or unknown-block(0,0)

  - by svoop

  I'm putting together a Dom0 and three DomU (all Gentoo) with kernel 3.5.7 and Xen 4.1.1. Each Dom has it's own md (md0 for Dom0, md1 for Dom1 etc).

• AHCI, Windows 7 and can only boot with Windows DVD present

  - by Rob Pridham

  Foolishly, I installed Windows 7 with my new SSD set to IDE. I would like to change it to AHCI. I have done this before, with a different motherboard. What happens: I set the controller to AHCI in the BIOS; I also check correct boot order On boot, I get the 'BOOTMGR not found' error I use the Windows Recovery Console on the DVD Diskpart etc can see the disks, and bootrec claims to have rewritten the MBR/bootloader I reboot, same problem Recovery Console again and it detects a problem, fixes, reboots Recovery Console again and it detects the OS, and a problem - fixes, reboots I ignore the 'press any key to boot from DVD' prompt Windows boots fine I restart without the DVD and I'm back to square one That optional 'press a key to boot from DVD' stage is something that the recovery process introduces - normally you have to choose to boot to the DVD at the BIOS stage. You also see this when installing Windows. I suspect that whatever temporary state that is is compatible with AHCI - but not the standard it returns to. I have done the msahci/iaStorV registry hacks to no avail (this worked with the previous board). I can put it back to IDE where normal service is resumed. The board is an Asus M5A99X, the southbridge is AMD SB950, and this is Windows 7 x64. I would quite like not to have to reinstall it again. Any ideas as to what I can do as a permanent fix?

• Winamp has slow /skipping video playback on Windows 7

  - by Roy Rico

  Hello, I have Windows 7 x64 (7600 90-day trial version) and Winamp 5.6 installed. When I play a video in Windows Media Player, the video plays smooth, however when I play a video in winamp, the video is mostly ok when played back at the original size (but not completely), but if I play it back in fullscreen, the playback gets really slow. The video's audio track plays just fine. I have a DELL XPS 420 computer (8GB of RAM) with a Nvidia GeForce 8800 CTS 512 video card. I've updated to the latest drivers. I have the default Windows 7 codecs, and the CCCP codec pack which used to be all I needed under Windows XP to play all types of videos. Are the codecs needed for Windows Y the same? What's going on? UPDATE: As suggested, I turned off Aero and winamp ran just fine again. So I just have to wait for winamp to be rewritten to work with the way Vista/Windows 7 runs? UPDATE 2: Winamp has updated their player, and it works great with Windows 7 now.

• What is the quickest and safest way to test new software and revert all changes, if needed?

  - by calbar

  I'm looking for Windows software that will allow me to quickly create a "checkpoint", do whatever I might need to do to my computer - install programs/drivers/updates, create/delete personal files, reboot the system multiple times, open questionable attachments - and then revert the entire system back to when the checkpoint was created. Essentially I want Windows Restore Points that save my personal files and partitions, too. It sounds like disk imaging might be the ticket, but creating them is much too slow and the restore process too involved... I'm hoping to sacrifice full disaster recovery for speed. Creating a checkpoint should be as close to one-click as possible, and rolling back should be a matter of selecting a restore point and rebooting. Ding! I'm familiar with Sandboxie, True Image Home "Try and Decide", Returnil, and a number of other "virtual system" apps that actively "catch" changes and allow you to commit or reject them. I'm not interested in these for a number of reasons - I prefer the "cut and dry" restore point approach. Finally, I'll note that I've just recently become aware of Comodo Time Machine. It sounds absolutely perfect, however, a quick skim through the user forums show more than a few horror stories of corrupted, unbootable systems. Any positive personal experience with the software to suppress my superstitions, or suggestions for more established alternatives would be greatly appreciated - Comodo Time Machine seems relatively new. Thanks for your help!

• Delegating account unlock rights in AD

  - by ewall

  I'm trying to delegate the rights to unlock user accounts in our Active Directory domain. This should be easy, and I've done it before... but every time the user tries to unlock an account (using the LockoutStatus tool), he gets denied with the error "You do not have the necessary permissions to unlock this account." Here's what I've done: I created a domain local group and added the members who should have the rights. This was created over a week ago, so the users have logged out and in again. In ADUC, I've used the Delegate Rights wizard on the OU which contains our user accounts to grant permissions to Read lockoutTime and Writer lockoutTime to the group, per MSKB 279723 I have double-checked the permissions were applied correctly in ADSIEdit. I have forced replication between all domain controllers to ensure the permission changes were copied over. The user testing it has logged out and in again to ensure he has any changes applied to his account. ...That covers all the bases I can think of. Anything else I could be missing?

• How do I encapsulate the application server from the web and database servers?

  - by SNyamathi

  So I've been doing some reading and it seems like the best practice would be to have separate database, application, and web servers. There are a few things that I've failed to understand - please feel free to recommend any reading materials that would address these topics. Database (assume MySQL) Application server communication: Does the database server do any sort of checks on the SQL commands sent / returned, or is it just a "dumb pipe" that responds to SQL commands by spitting back data? Application server (assume Tomcat) Web Server Almost the reverse here, is it the web server that is more of a pipe to the internet that forwards requests to the application server and spits back responses? I'm not wording this well, but I'm trying to ask - is it the application server that is responsible for validating data received by from requests? ex: Parsing POSTs Validating user logins Encrypting decrypting data Furthermore, how do these two servers communicate? I'm trying to keep things as flexible as possible here, so while I could write a web server in Java and use Java to communicate between the web and app server, that doesn't sound very modular. What if I want to use Python or some other language to replace the web server later on? What if I want to make a non-web facing application used in house written in C++ or something.

• "Dictionary problem." Error with VMPlayer

  - by George Mauer

  I'm pretty new to using vmware virtualization (been a virtualbox user) so I'm hoping you guys can help me out. I recently got an external usb disk containing a vm for a client, downloaded vmplayer, set it up with "Open a Virtual Machine", ran it, easy as pie. After working with it a bit this morning, I shut the VM down and now trying to start it back up again I get this: I tried removing the vm from my library, now it happens whenever I try to add it back in. In the meantime, I can still access other virtual machines so it seems like the problem might be with the virtual disk. So two questions: This is obviously not a very helpful error message. Where can I go to get more information? My Application EventLog doesn't contain anything from VMWare. What steps can I take to fix the problem? Edit: A couple more pieces of information. I did not take any snapshots. I don't think VM Player even has that ability. I have a zip file of (what I assume) is the state of the VM when it was sent to me. I cannot unzip it as it is huge and simply requires more HD space than I have available but I did extract the vmx file and examine it. Other than the UUIDs and the fact that mine reads cleanShutdown = "FALSE" they are identical. The log contains the following lines Jun 23 10:11:18.080: vmx| SNAPSHOT: SnapshotConfigInfoRead: Unable to load dict from 'E:....\MachineName.vmsd'.

• Why can't I get out of display mirror mode?

  - by Roy Smith

  I've been running Ubuntu (10.04.1 LTS, 64-bit) for a while and just replaced my hardware with a faster machine with an ATI Radeon HD 5700 video card. I've got twin 1920 x 1080 displays. I downloaded the latest driver (ati-driver-installer-10-9-x86.x86_64.run) from the ATI web site and installed that. I've gone through a few rounds of playing with /etc/X11/xorg.conf, and can't get things right. At the moment, it's in display mirroring mode, and I can't figure out how to get it out of mirror mode. If I run Monitor Preferences, there's a "Same image in all monitors" checkbox. If I uncheck that, the little preview window switches to show two monitors. When I click Apply, it asks me to log out and log back in again. When I do that, I'm right back to mirrored mode. What's really weird is that I'm currently running a copy of xorg.conf from a coworker's machine. He's got identical hardware, and his display works fine. So, I'm inclined to think there's something else going on other than the conf file. Any ideas what might be wrong?

• How can I avoid my web browser from redirecting to localhost using WAMP in Windows7?

  - by Josh

  I'm currently using Windows 7 with WAMP to try and work on some software, but my web browsers will not accept cookies from the "localhost" domain. I tried creating a few bogus domains in my hosts file by pointing them to 127.0.0.1 but when I type them in I am automatically redirected back to localhost. I have also configured virtualhosts in apache to correspond with the domains I added to the hosts file and it still redirects back to localhost. Is there anything special I must do on Windows 7 to get around this localhost redirect? Thanks for looking :) I'll include my host file here: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost 127.0.0.1 magento.localhost.com www.localhost.com Thanks for looking :)

• How to take search query and append modifers to the end of it

  - by Kimber

  This is a greasemonkey question. What I'm trying to do is modify an old google discussions script. What were wanting to do is be able to take the google search query and add modifiers to the end of it. Like this: search query: "superuser" modifiers: inurl:greasemonkey+question end result: "superuser" inurl:greasemonkey+question The old script creates a new div within the "hdtb_more_mn" element which is where you get the new discussions tab. However, since the "tbm=dsc" option to do a discussion search has died, this script no longer works. Hence the need to add modifiers to your searches. I tried to edit the script, but it appends the modifiers to the end of the url which includes "&client=firefox-a&hs=8uS&rls=org.mozilla:en-US:official". This means you're also searching for the above as well as your query, which doesn't work. I would like to be able to append the modifiers @ the end of the search querty, rather than the whole URL. I'm just not sure how to code it to where it adds the below "&tbm=" stuff within "discussionDiv.innerHTML" to the end of the query. The google search id seems to be, "gbqfq" for the search box, but I'm not sure how to add this id. Here is the old script // ==UserScript== // @name Add Back Google Discussions // @version 1.4 // @description Adds back the Discussion filters to Google Search // @include *://*.google.tld/search* // ==/UserScript== var url = location.href; if (url.indexOf('tbm=dsc') < 0) addFilterType('dsc', 'Discussions'); function addFilterType(val, name) { var searchType = document.getElementById('hdtb_more_mn'); var discussionDiv = document.createElement('DIV'); discussionDiv.className = 'hdtb_mitem'; discussionDiv.innerHTML = '<a class="q qs" href="'+ (url.replace(/&tbm=[^&]*/g,'') + '&tbm=' + val) +'">'+name+'</a>'; searchType.innerHTML += discussionDiv.outerHTML; } Thanks for any help, or suggestions on who to ask. Google Chrome has an extension for discussion searches, but FF doesn't seem to have one as of yet, which is why I'm trying to modify the above.

• Windows 7 - media sharing extremely flakey (XBox 360)

  - by Nathan Ridley

  I have constant headaches with Windows Media Library sharing, which I'm using to share my video library (a whole lot of AVI files on my computer's hard drive) with the XBox 360. I have the whole setup working, so setup and basic configuration is not an issue. The issue is that Windows Media Library frequently fails to notice additions and modifications to the "watched" folders. Not only that, but often after I've added something new to the library, it fails to transmit this new library information to the 360, as is demonstrated by the fact that, using that 360, I navigate to my video library and the new folders don't show up in the list. Often the only way to get the 360 to see the changes is to exit out of "Videos" on the 360, then remove all videos from Windows Media Library, go back into videos on the 360 to confirm that nothing is shared, then re-add a few videos (but not too many) in Windows Media Library, then go back into the videos in the 360. The whole thing is a real pain in the bum and I really wish I could just add all my videos to Windows Media Library and have it keep watch without me having to kick it, and have the 360 pick up changes without me having to constantly rebuild the library. Any ideas?

• How to send from my Z88 to my PC

  - by Bevan

  I've got a Cambridge Z88 that I want to get working with my PC. Around 6 years ago - in 2004 - I made heavy use of my Z88 to do a whole bunch of writing on the train while commuting to and from work. The Z88 is solid state, lightweight and has a full size silent keyboard, so it works very well as a writing instrument. I still have the serial cable I soldered up back then and used successfully in 2004. It has these connections: Z88 9 pin ----- ------- 2 TxD ------> RxD 2 3 RxD <------ TxD 3 7 GND <-----> GND 5 4 RTS ------> CTS 8 5 CTS <-+ RTS 7 8 DCD <-+---- DTR 4 9 DTR ----+-> DCD 1 +-> DSR 6 Unfortunately, I haven't been able to find my notes from 2004 that describe how I got it to work back then. I've spent several hours trying to Google a result, but to no avail. I'm pretty sure the cable is fine - after all, it's what I used successfully six years ago, and I've checked it out with a multimeter - so I'm focusing on the PC end of things, which is where I'd like some assistance. Q1: In my recent attempts, I've been using both Hyperterminal (as built into Windows XP) and the command line (copy com2: con:), but with no success. What's a good (better!) serial communications application to use? Is there one that allows me to see as deep as the signalling that's occurring on the wire? Q2: If you have a Z88 that works correctly with your PC, what software do you use on the PC end, and what's the pinout of your cable? I'm pretty sure that the Z88 itself is working properly: When using the built in Import/Export tool to send a file, I see different behaviour when my serial cable is connected compared to disconnected. When disconnected, the transmission appears to work, with a progress meter counting up and then finishing; when connected, nothing happens 'cept a timeout if I wait long enough.

• Slackware - Assigning routes (IP address ranges) to one of many network adapters

  - by Dogbert

  I am using a Slackware 13.37 virtual machine within VirtualBox (current). I currently have a number of Ubuntu VMs on a single server, along with this Slackware VM. All VMs have been set up to use "Internal Network" mode, so they are all on a private LAN, and can see each other (ie: share files amongst themselves), but they remain private from the outside world. On on the these VMs (the Slackware one), I need to be able to grant it access to both this private network, and the internet at large. The first suggestion I found for handling this is to add another virtual network adapter to the VM, then set it to NAT. This results in the Slackware VM having the following network adapter setup: -NIC#1: Internal Network -NIC#2: NAT I want to set up the first network adapter (NIC#1) to handle all traffic on the following subnets: 10.10.0.0/255.255.0.0 192.168.1.0/255.255.255.0 And I want the second virtual network adapter (NIC#2) to handle everything else (ie: internet access). May I please have some assistance in setting this up on my Slackware VM? Additionally, I have searched for similar questions on SuperUser and Stackoverflow, but they all seem to pertain to my situation (ie: they all refer to OSX, or Ubuntu via the use of some UI-based tool). I'm trying to do this on Slack specifically via the command-line. Thanks!

• lenovo x1 carbon windows 8 frequent wifi disconnect issue

  - by hIpPy

  I'm having frequent wifi disconnects on my Lenovo X1 Carbon Touch laptop. I got this laptop 2 months back and it has been happening ever since about 3-5 times a day and 10 times a week on average. I've Frontier Fios internet. Power connected or not does not matter. Once I get disconnected, I try below to connect again in that order: turn Airplane mode on and off, troubleshoot network problems windows troubleshooter), restart the laptop I'd find that the WiFi adapter would get disabled and sometimes windows troubleshooting would help but more than often I'd end up restarting the laptop. A week back, I upgraded my wifi network adapter drivers (now Intel, version 15.5.6.48, 10/3/2012). I still get disconnected frequently but turning Airplane mode on and off gets me connected again. So the driver update did help. Windows 8 is updated. None of the other devices (nexus, iphone phones, nexus7, ipad tablets) would have wifi issues when my laptop would get disconnected. config: Intel(R) Centrino(R) Advanced-N 6205 (WiFi network adapter) Microsoft Windows 8 Pro Microsoft Windows [Version 6.2.9200] x64-based PC LENOVO System Model: 3443CTO X1 Carbon Touch I recently noticed this log message When I got disconnected in event viewer: Your computer was not assigned an address from the network (by the DHCP Server) for the Network Card with network address 0x[XXXXXXXXXXXX]. The following error occurred: 0x79. Your computer will continue to try and obtain an address on its own from the network address (DHCP) server. Any idea?

• Where do these mysterious DNS lookups come from and why are they slow?

  - by Hongli

  I have recently obtained a new dedicated server which I'm now setting up. It's running on 64-bit Debian 6.0. I have cloned a fairly large git repository (177 MB including working files) onto this server. Switching to a different branch is very very slow. On my laptop it takes 1-2 seconds, on this server it can take half a minute. After some investigation it turns out to be some kind of DNS timeout. Here's an exhibit from strace -s 128 git checkout release: stat("/etc/resolv.conf", {st_mode=S_IFREG|0644, st_size=132, ...}) = 0 socket(PF_INET, SOCK_DGRAM|SOCK_NONBLOCK, IPPROTO_IP) = 5 connect(5, {sa_family=AF_INET, sin_port=htons(53), sin_addr=inet_addr("213.133.99.99")}, 16) = 0 poll([{fd=5, events=POLLOUT}], 1, 0) = 1 ([{fd=5, revents=POLLOUT}]) sendto(5, "\235\333\1\0\0\1\0\0\0\0\0\0\35Debian-60-squeeze-64-minimal\n\17happyponies\3com\0\0\1\0\1", 67, MSG_NOSIGNAL, NULL, 0) = 67 poll([{fd=5, events=POLLIN}], 1, 5000) = 0 (Timeout) This snippet repeats several times per 'git checkout' call. My server's hostname was originally Debian-60-squeeze-64-minimal. I had changed it to shell.happyponies.com by running hostname shell.happyponies.com, editing /etc/hostname and rebooting the server. I don't understand the DNS protocol, but it looks like Git is trying to lookup the IP for Debian-60-squeeze-64-minimal as well as for happyponies.com. Why does Debian-60-squeeze-64-minimal come back even though I've already changed the host name? Why does Git perform DNS lookups at all? Why are these lookups so slow? I've already verified that all DNS servers in /etc/resolv.conf are up and responding slowly, yet Git's own lookups time out. Changing the host name back to Debian-60-squeeze-64-minimal seems to fix the slowness. Basically I just want to fix whatever DNS issues my server has because I'm sure they will cause more problems that just slowing down git checkout. But I'm not sure sure what the problem exactly is and what these symptoms mean.

• One Windows Domain workstation can ping gateway but gets no internet access

  - by dindeman

  One of the (Windows XP SP3) workstations of our Windows Domain could not access internet anymore, this problem suddenly happened overnight. The domain controllers (there are three of them) are all running Windows Server 2008. First I compared the output of ipconfig /all on the faulty workstation with the output of a working workstation and it was just fine as it had always been. In particular the default gateway was correct and always remained pingable from the faulty workstation. I guessed that something was wrong with the DHCP service and I restarted the DHCP server service on all of our three DCs as well as the DHCP client service on the faulty workstation. This didn't solve the issue. I then thought of renewing the DHCP lease with ipconfig /release and ipconfig /renew and here is my first question: why did this never work? The same IP address (192.168.0.45) kept being assigned despite all my attempts to renew it (note that all our workstation are getting their TCP/IP automatically.) Even by leaving the domain and changing the computer name the same address was yet again obtained... Anyway I then proceeded to switch the TCP/IP configuration for that machine manually to another free valid IP address (192.168.0.41)... and then the internet access came back! I then cleared any traces of the previous IP in the DHCP leases list and in the DNS tables of our DCs and, after setting back the TCP/IP configuration to 'automatic', finally, the new lease would be granted (192.168.0.41) alongside with the internet access. My second question: what went suddenly wrong with the original IP address?
