• How do I run a stable Windows XP kvm guest on Ubuntu 10.04?

  - by Jean-Paul Calderone

  I have three Windows XP guests running on a recently upgraded 64-bit Ubuntu 10.04 system. Occasionally (on the order of once every few days), one of the guests will become non-responsive and the kvm process on the host which is running that guest will start consuming 100% CPU. It will continue to do so until it is killed. When restarted, it will be fine for a while, and then the issue repeats. The kvm command line used to run all three guests is this: /usr/bin/kvm -S -M pc-0.12 -enable-kvm -m 1024 -smp 1 -name bigdog21vmxp1 \ -uuid ea47ff84-125b-16f7-9a4d-a6d0d8bab46a \ -chardev socket,id=monitor,path=/var/lib/libvirt/qemu/bigdog21vmxp1.monitor,server,nowait \ -monitor chardev:monitor \ -localtime \ -boot c \ -drive file=/var/lib/libvirt/images/windowsxp-1.qcow2,if=ide,index=0,boot=on,format=qcow2 \ -net nic,macaddr=54:52:00:02:06:0e,vlan=0,name=nic.0 \ -net tap,fd=58,vlan=0,name=tap.0 \ -chardev pty,id=serial0 \ -serial chardev:serial0 \ -parallel none \ -usb \ -usbdevice tablet \ -vnc 127.0.0.1:1 \ -k en-us \ -vga cirrus \ -soundhw es1370 Why do the systems misbehave this way sometimes? And what configuration can I change in order to fix it? Or, if the problem is due to a bug in kvm, what is the process for isolating a kvm failure so that the developers have a chance of fixing it?

• Windows 2008 Incoming Connection: Where/How is Server IPv4 address defined

  - by revelate

  We're evaluating a VM hosted externally which runs Windows Server 2008 R2 Web Server Edition and wish to access it via a VPN connection for maintenance and administration. RRAS isn't included in Web Server Edition, but it does have a form of VPN server called "Incoming Connections". This appears to work well and even supports multiple simultaneous connections. As we'll be using this VPN regularly we'd like to know if this is a viable solution or if we'd be better off upgrading to Standard Edition and full-fledged RRAS. In particular we're accessing the VM via the Private IP given by the Incoming Connection (currently 169.254.135.207) so we'd like know: if the server private IP might change every so often? if so is there any way to define it manually? or should we be using the server name rather than the private IP address? if so how can we be sure that it will resolve correctly? Name resolution over the "Incoming Connection" has worked on and off during our tests. Thanks for your help

• Unable to add IPv6 address to sendmail access list

  - by David M. Syzdek

  I am running Sendmail 8.14.4 on Slackware 13.37. I have the following in my /etc/mail/access file and it works without any errors: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite The above configuration also allows me to send an e-mail via IPv6 to a local user on the mail server. However, it does not allow my office to relay via IPv6. I have tried two ways of adding IPv6 networks to my access file. Method 1: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:IPv6:2001:470:b:84a RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite Method 2: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:[IPv6:2001:470:b:84a] RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite However whenever I try using either method 1 or 2, I am unable to relay e-mail messages through the host. /var/log/maillog entry: May 31 11:57:15 freshsalmon sm-mta[25500]: ruleset=check_relay, arg1=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], arg2=IPv6:2001:470:b:84a:223:6cff:fe80:35dc, relay=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], reject=553 5.3.0 RELAY # Net:office Test session from telnet: syzdek@blackenhawk$ telnet -6 freshsalmon.office.example.com 25 Trying 2001:470:b:84a::69...

• XBMC DVB-T and Played Video filling screen

  - by Tubs

  I have a small PC running as an XBMC attached to a Samsung le37m87bd. The PC isn't powerful enough to output a full HD 1080 image at 1920x1080 which is the TVs native resolution (about every 1/2 a second things go extra fast, I assume skipping frames), so I want to reduce this. Annoyingly, the TV does not support any other widescreen resolutions. (720 etc) If I use a a 4:3 image, the TV stretches it to be the 16:9, however, all 16:9 content is stretched sideways as XBMC is sending out a 4:3 image with a 16:9 image inside. Is there anyway I can force XBMC to compensate for this, ie stretch vertically so that black bars are removed, but not stretched horizontally?

• TeamCity NuGet private feed - Credentials

  - by Gaui

  I installed TeamCity and enabled NuGet server, both Authenticated Feed and Public Feed. When I try to push packages to the server with the following command: > nuget push package.nupkg [API-Key-here] -s http://myserver/httpAuth/app/nuget/v1/FeedService.svc/ I get the following prompt: Please provide credentials for: http://myserver/httpAuth/app/nuget/v1/FeedService.svc/ And asks me for both "UserName" and "Password". I've tried entering credentials for TeamCity administrator and Windows administrator, but nothing works. So I tried pushing to the Public Feed with the following command: > nuget push package.nupkg [API-Key-here] -s http://myserver/guestAuth/app/nuget/v1/FeedService.svc/ Then I get the following: Failed to process request. 'Method Not Allowed'. The remote server returned an error: (405) Method Not Allowed.. Regarding the Authenticated Feed, what credentials are they and where do I specify them and why is the Public Feed not working?

• Windows 7 context menu not disappearing after selecting an option

  - by RaYell

  I have a very annoying problem for several days now. Whenever I open context menu in any application on my Windows and select any option it does not disappear correctly. The option I choose is always visiable and what's even more annoying it's beign displayed over any other application. The only solution I've found at the moment is to change a display resolution and restore it. That makes it disappear but it's very annoying because I have to do that always after using context menus. Is there any fix for this problem? Below is the screenshot of how it appears on screen:

• Can Resource Governor for SQL Server 2008 be scripted?

  - by blueberryfields

  I'm looking for a method to, in real-time, automatically, adjust Resource Governor settings. Here's an example: Imagine that I have 10 applications, each hitting a different database on the same database machine. For normal operations, they do not hit the database very hard, so I might want each one to have 10% CPU power reserved. Occasionally, though, one or two of them might spike, and run an operation which could really use the extra power to run faster. I'd like to be able to adjust to compensate (say, reducing the non-spiking apps to 3%, and splitting the difference between the spiking apps). This is a kind of poor man's method of trying to dynamically adjust resource allocation and priorities. Scripts (or something script-like) is preferred, since the requirement is for meta-level adjustments to be possible in real-time, also.

• Apache2 Segmentation fault with wsgi_module

  - by a coder

  Apache 2.2.3 is running as an existing web server under RHEL 5. Attempting to set up Trac using wsgi_module. RHEL 5 ships with python 2.4, so in order to use the current version of Trac (1.0) I needed to install it with easy_install-2.6. Trac works with the default mod_python, however users strongly encourage not using this module as it is officially dead. Using RHEL's package manager, I downloaded/installed python26-mod_wsgi.so. I backed up the httpd.conf, then made the following additions: LoadModule wsgi_module modules/python26-mod_wsgi.so #...# WSGIScriptAlias /trac /www/virtualhosts/trac/deploy/cgi-bin/trac.wsgi <Directory /www/virtualhosts/trac/deploy/cgi-bin> WSGIApplicationGroup %{GLOBAL} Order deny,allow Allow from all </Directory> Next I moved trac.conf to trac.conf.bak (contains mod_python calls). I tested the configuration using: apachectl configtest Syntax is OK. So I reloaded the server config using: service httpd reload At this time, all virtualhosted sites stopped responding. I restored my backup copy of httpd.conf, reloaded the server config, and the virtualhosted sites are being served again. A quick look at the httpd error_log shows: [Mon Oct 08 10:20:04 2012] [info] mod_wsgi (pid=28282): Initializing Python. [Mon Oct 08 10:20:04 2012] [info] mod_wsgi (pid=28280): Attach interpreter ''.

• Windows Virtual Machines will not run

  - by jlego

  I'm trying to setup a few virtual machines to use for testing websites in the various old versions of IE. I had Microsoft Virtual PC working on an older machine using XP mode and 2 other VHD's from Microsoft that allowed me to test in IE6-IE8. I've recently gotten a new work machine and am trying to set up the VMs again for testing, however nothing seems to be working. Both the old and the new system run Windows 7 64-bit Ultimate with AMD processors. I downloaded Virtual PC & XP mode from here http://www.microsoft.com/windows/virtual-pc/download.aspx and go through the installation process. XP mode is installed, but when I try to run it it goes through the initial setup process only to fail when it is almost complete with the error "Cannot Complete Setup". (After googling I see that this might be a conflict with my processor) I download other VHD's from here http://www.microsoft.com/windows/virtual-pc/download.aspx in order to get the other versions of IE and try to set those up in Virtual PC as well. I click on them to start the machine and both Windows 7 with IE8 and Windows Vista with IE7 just hang at a black screen. I try to use Virtual Box instead, and I get Windows XP with IE6 running, but I have no internet connection in the VM. I try all different settings and try to google the correct settings but nothing seems to work. When I load the VM, XP shows that its found new hardware but it needs the drivers. One of these pieces of hardware is the network adapter, but I can't connect to the internet to download the driver in the guest OS. VirtualBox tells me I need to install extensions in order for things to function properly. I go through the installation process in the guest OS and restart the VM, however now XP is asking for validation and I can't access the VM. I try installing the other 2 OS (Vista & 7) but I get a BSOD right after the startup screen appears and the VM restarts itself. I'm getting so frustrated trying to make this work, I would really appreciate any assistance on getting the VMs up and running or any alternatives for testing websites in Internet Explorer.

  I'm trying to set up a local webserver on my network. I want to be able to be able to access the webserver from any machine inside my network w/out authenticating. and two extra domains need access to it w/out authenticating. Everyone else I would like to authenticate in. so far, I can get to it from inside my network. and the two extra domains can access my webserver, but everyone else is just hanging. They don't get an authentication or anything. can anyone tell me what I'm doing wrong here?

• Getting jerky backgrounds on Win7 on iMac 27'' 2560x1440

  - by JohnIdol

  I installed Win7 on bootcamp on my new iMac 27'' (ATI videocard) and everything was good until recently I noticed that the default win7 background (then one on the background on login) looked jerky. When I say jerky I mean the kind of jerky you get if you can't display enough colours, and instead of nice fading shades you just get stripes and jerky patterns. I am on native resolution but even if I go down to 1920x1080 I get the same. This might have happened after a firmware update but as I don't use windows very often I am not too sure it's what caused it. Oh, and when I am playing games everything looks OK (as in not jerky!). Any help appreciated!

• Robocopy silently missing files

  - by John Hunt

  I'm using Robocopy to sync data from our server's hard disk to an external disk as a backup. It's a pretty simple solution but pretty much the best/easiest one we could come up with - we use two external disks and rotate them offsite. Anyway, here's the script (with the comments taken out) that I'm using to do it. It works very well, it's quick and almost 100% complete - however it's acting pretty strange with a few files (note company name has been changed in paths to protect the innocent): @ECHO OFF set DATESTAMP=%DATE:~10,4%/%DATE:~4,2%/%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2% SET prefix="E:\backup_log-" SET source_dir="M:\Company Names Data\Working Folder\_ADMIN_BACKUP_FILES\COMPA AANY Business Folder_Backup_040407\COMPANY_sales order register\BACKUP CLIENT FOLDERS & CURRENT JOBS pre 270404\CLIENT SALES ORDER REGISTER" SET dest_dir="E:\dest" SET log_fname=%prefix%%date:~-4,4%%date:~-10,2%%date:~-7,2%.log SET what_to_copy=/COPY:DAT /MIR SET options=/R:0 /W:0 /LOG+:%log_fname% /NFL /NDL ROBOCOPY %source_dir% %dest_dir% %what_to_copy% %options% set DATESTAMP=%DATE:~10,4%/%DATE:~4,2%/%DATE:~7,2% %TIME:~0,2%:%TIME:~3,2%:%TIME:~6,2% cscript msg.vbs "Backup completed at %DATESTAMP% - Logs can be found on the E: drive." :END Normally the source would just be M:\Comapany name data\ but I altered the script a bit to test the problem. The following files in the source are not copied to the dest: Someclient\SONICP~1.DOC Someclient\SONICP~2.DOC Someclient\SONICP~3.DOC However, files in the same directory named: TIMESH~1.XLS TIMESH~2.XLS are copied. I'm able to open the files that aren't copied with no trouble at all, and they certainly weren't opened when I ran robocopy so it's not a locking issue. Robocopy is running as administrator so it's not a permissions issue. There's no trace these files were even attempted to be copied as there are no errors being output in the log or in my command prompt. Does anyone have any suggestions as to what this might be? Busted hard disk? Cheers, John.

• Logging Apache2 payload to evaluate SOAP message

  - by Phil

  I am trying to log webservice specific information with Apache (Apache acts as a load-balancer by use of mod_jk). For instance I want to know how long the responsetime of each webservice-call takes. To do this I definitely would need to know the name of the webservice-method in the log-file. As a matter of fact, the name of the webservice-method is wrapped in the SOAP-body, to which I have no access to with the default-configuration. Does anybody know an Apache module to extend the log-information? Or are there any other ideas to solve this challenge? Thx!

• VMware and Windows Activation

  - by Peter M

  Yesterday I installed Slysoft's Virtual CloneDrive in order to mount an iso for some software installation on my host system (XP Pro SP3) This morning I fired up VMware and made a linked clone of an existing XP vm in order to do some software testing. This is the sort of thing that I do all the time, and the base XP vm that I clone was activated a long long time ago. The surprise today was that the newly cloned vm was no longer activated and XP cited major changes in hardware as the reason. I repeated the test with a full clone of the base system and got the same message. I then started up my base vm and it seemed to be activated, yet another vm (which I fully cloned from the base vm a long time ago) now started reporting that XP was not activated. At this point I guessed that Virtual DriveClone might have been the source of my hardware differences so I uninstalled it and rebooted. After this I made a new linked clone and full clone of the base vm and XP did not complain about not being activated. So I seem to be back to where I was before installing Virtual DriveClone with the exception that that one particular XP vm continues to complain about activation (even though 4 or 5 other XP vm's are fat and happy) Now to my questions: Why would adding Virtual CloneDrive to the host system affect XP activation on the vm's? From their point of view I would have thought that the environment had not changed as I had not enabled any new hard drives in their systems. Or is adding a hard drive to the host system enough to upset XP activation? Since this event, one of my fully cloned vm's is still reporting that XP is not activated even though I have removed Virtual CloneDrive. Is there anyway to convince XP that it is on the same system as yesterday? Or are my only options to do an activation or restore the vm from a previous backup?

• Set Display Refresh Rate in OSX w/o External Utilities

  - by codedonut

  I have an iMac and an LG Flatron connected as a secondary monitor. The recommended resolution for the flatron is 1680x1050 @ 65.290 Hz (horiz), 59.954 Hz (vert). For some reason, OSX is choosing a slightly different set of scan rates and this is currently my best guess of why the monitor goes into power saving mode when connected to the iMac (but works fine on a PC). Now, I resolved this by installing switchResX and fudging the scan rates according to the specs in the manual. But how does one change these rates w/o 3rd party tools? Which config files need editing? Thanks

• Managing ip6tables (or an alternative firewall) remotely

  - by Matthew Iselin

  I'm working with IPv6 and have run into an issue configuring ip6tables on our main router in order to control what can come into the network. A default DROP rule in the FORWARD section has worked well (obviously leaving ESTABLISHED,RELATED as ACCEPT) to keep internal clients' open ports from being accessed. However, running an ip6tables command for every little change is unwieldy. Whilst we are able to continue creating rules manually, I'm wondering if there's some sort of management interface we could use to create the rules quickly and easily. We're looking to be able to save time working on our firewall as well as providing a simple method for modifying rules for those who will eventually replace us. I know webmin (heavily locked down on our network, naturally) has support for modifying iptables rules, but seemingly no support for ip6tables. Something similar would be fantastic. Alternatively, suggestions for a firewall solution apart from iptables/ip6tables which can be managed remotely wouldn't be out of order. A web interface for management is certainly preferable, even if it is just a wrapper with shiny buttons over the raw config files.

ScriptAlias /cgi-bin/ "D:/opt/apache/cgi-bin/" ... <Directory "D:/opt/apache/htdocs"> Options Indexes FollowSymLinks ExecCGI AllowOverride None Order allow,deny Allow from all </Directory> <Directory "D:/opt/apache/cgi-bin/"> AllowOverride None Options ExecCGI Order allow,deny Allow from all </Directory> (I know it's dumb but it's only a testing machine :D.) Now, I have d:\opt\apache\cgi-bin\expired.pl and I expect GET /licensecheck.php?code=123456. And I wish to fake client into thinking it speaks with /licensecheck.php, but actually return data by \expired.pl. What I tried was setting following at the end of http.conf: RewriteEngine on RewriteRule ^/licensecheck.php$ /cgi-bin/expired.pl [T=application/x-httpd-cgi,L] ...but it keeps 404-ing me, looking for cgi-bin directory (not cgi-bin\expired.pl) in my DocumentRoot! [error] [client 127.0.0.1] script not found or unable to stat: D:/opt/apache/htdocs/cgi-bin /cgi-bin/expired.pl and all other scripts in /cgi-bin/ work as expected, Only way I could make it work was actually putting the \expired.pl to DocumentRoot, but I don't want this, I want my cgi-bin neatly separated :)

• Using Confluence with virtual hosts and mod_proxy

  - by Marcus

  Hi @all, on a test server I have installed the latest version of Confluence. I configured a apache with ajp. But I have a problem, when I login in Confluence, I get the following error message: Not Found The requested URL / / homepage.action was not found on this server. The problem seems to be known, I found following Link: http://confluence.atlassian.com/display/DOC/Using+Apache+with+virtual+hosts+and+mod_proxy But unfortunately the forwards have not helped, I still get the error messages. Does anyone have any idea how I could solve the problem? The following Apache configuration I have set up: LoadModule proxy_module /usr/lib/apache2/modules/mod_proxy.so LoadModule proxy_http_module /usr/lib/apache2/modules/mod_proxy_http.so LoadModule proxy_ajp_module /usr/lib/apache2/modules/mod_proxy_ajp.so <IfModule proxy_http_module> ProxyRequests Off ProxyPreserveHost On <Proxy *> Order deny,allow Allow from all </Proxy> <Location /> Order allow,deny Allow from all </Location> ProxyPass / http://localhost:8080/ ProxyPassReverse / http://localhost:8080/ </IfModule>

• ssh login successful, but scp password gives me "Permission denied"

  - by YANewb

  I'm trying to get some blogging software up on an organizational remote server. I tried to set up a SSH Key but was having problems and decided that getting the blog up and running was more important than dealing with the SSH Key issue, so I ssh-keygen -R remoteserver.com. Now I can successfully login with ssh -v [email protected] and the correct password. Once logged in I can move around and read any file and directory that I should be able to read. But when I try to edit an existing -rw-r--r-- file with VIM, it shows up as read-only, if I try to edit permissions I get chmod: file.ext: Operation not permitted, and if I try to scp a new file from my local machine I'm prompted for the remote user's password, and then get scp: /home/path/to/file.ext: Permission denied. Since I didn't have any of these problems before I tried to set up the ssh key, I suspect these anomalies are a side effect of that, but I don't know how to troubleshoot this. So what does a foolish server-newb, such as myself, need to do to get edit capability back as a remote user? Addendum 1: My userids are different between my local machine and the remote server. For ssh I ssh -v [email protected]. if I whoami I get remoteuser For scp I scp file.ext [email protected]:/path/to/file.ext from the local directory with file.ext while logged in as the local user. if I whoami I get localuser The ls -l for two different files I've tried scp: -rw-r--r--@ 1 localuser localgroup 20 Feb 11 21:03 phpinfo.php -rw-r--r-- 1 root localgroup 4 Feb 11 22:32 test.txt The ls -l for the file I've tried to VIM: -rw-r--r-- 1 remoteuser remotegroup 76 Jul 27 2009 info.txt Addendum 2: In the past I've set up ssh-keys for git repositories. I don't want to completely destroy them, so in an attempt to follow a deer's train of thinking I renamed my ~/.ssh/ to ~/.ssh-bak/, then tested the different types of access. The abridged version of the terminal commands and results is below; I think everything is working until the 8th line from the end. localcomputer:~ localuser$ ssh -v [email protected] OpenSSH_5.2p1, OpenSSL 0.9.8l 5 Nov 2009 debug1: Reading configuration data /etc/ssh_config debug1: Connecting to remoteserver.com [###.###.###.###] port 22. debug1: Connection established. debug1: identity file /Users/localuser/.ssh/identity type -1 debug1: identity file /Users/localuser/.ssh/id_rsa type -1 debug1: identity file /Users/localuser/.ssh/id_dsa type -1 debug1: Remote protocol version 2.0, remote software version OpenSSH_5.8p2 FreeBSD-20110503 debug1: match: OpenSSH_5.8p2 FreeBSD-20110503 pat OpenSSH* debug1: Enabling compatibility mode for protocol 2.0 debug1: Local version string SSH-2.0-OpenSSH_5.2 debug1: SSH2_MSG_KEXINIT sent debug1: SSH2_MSG_KEXINIT received debug1: kex: server->client aes128-ctr hmac-md5 none debug1: kex: client->server aes128-ctr hmac-md5 none debug1: SSH2_MSG_KEX_DH_GEX_REQUEST(1024<1024<8192) sent debug1: expecting SSH2_MSG_KEX_DH_GEX_GROUP debug1: SSH2_MSG_KEX_DH_GEX_INIT sent debug1: expecting SSH2_MSG_KEX_DH_GEX_REPLY The authenticity of host 'remoteserver.com (###.###.###.###)' can't be established.
