• Hostname and SSL (apache) issue on Debian

  - by user105566

  I have been trying to setup SSL virtual host ServerAdmin [email protected] ServerName moclm.tap.pt DocumentRoot /var/www/tapme/ <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow Deny from all Allow from 127.0.0.0/255.0.0.0 ::1/128 </Directory> <Directory /var/www/tapme/> Options -Indexes FollowSymLinks MultiViews AllowOverride All #Order allow,deny #allow from all </Directory> SSLEngine on SSLCertificateFile /etc/ssl/moclm.cer SSLCertificateKeyFile /etc/ssl/moclm.pem </VirtualHost> For some reason, the server automatically redirect to SSL (http:// to https://). The apache is not configured to redirect and application was working fine on port 80 only. I have no knowledge how the internal network works as i am working remotely. The SSL error logs show: [Tue Oct 02 22:40:32 2012] [error] Hostname linemnt01.tap.pt provided via SNI and hostname moclm.tap.pt provided via HTTP are different I thought may be the hostname has some issue and have changed the hostname of the server from "linemnt01.tap.pt" to "moclm.tap.pt" but the issue is still there. I am getting the following error on browser: Bad Request Your browser sent a request that this server could not understand. i have /etc/hosts: 127.0.0.1 localhost.localdomain localhost moclm.tap.pt moclm and openssl returns: openssl verify -CAfile cert-CA.cer moclm.cer moclm.tap.pt.cer: OK I have been trying to troubleshoot the issue but no luck.

• Recommendations for good FTP server for Win 2008 x64

  - by sfhtimssf1970

  I spent a bunch of time learning/configuring the "all new and better" FTP feature for IIS7. In my opinion, it still fails hard: In order to have multiple FTP sites on the same machine, you have to use host|user usernames (like domain.com|jason) for every account. Using IIS Manager auth doesn't seem to work at all. I'm sure I'm doing something wrong, but I can't figure out what the hell it is. I've read all the official articles on it and configured it a hundred different ways. Doesn't play well with passive connection types. That has to be disabled on the client in order for it to work. Doesn't have any way to allow one user to see multiple sites no matter what binding they are connected to. For instance, if "jason" connects to ftp.domain.com, he should be able to see domain2.com, domain3.com without seeing domain4.com and domain5.com. It takes an act of God to set this up with IIS7. So I'm wanting to install a third party FTP server instead. I've looked at FileZilla both ZFTPServer. Anyone know of any pros/cons on these? Any other recommendations?

• JBoss7 load balancing with mod_proxy_balancer - session not working

  - by Phil P.

  I am trying to set up mod_proxy_balancer for routing requests to 2 jboss7-servers. For the time being I am testing this setup on my local machine, using following config in httpd.conf: ProxyRequests Off <Proxy \*> Order deny,allow Deny from all </Proxy> ProxyPass / balancer://mycluster/ stickysession=JSESSIONID|jsessionid scolonpathdelim=On <Proxy balancer://mycluster> BalancerMember http://localhost:8080 route=node1 BalancerMember http://localhost:8081 route=node2 Order allow,deny Allow from all </Proxy> and in the standalone.xml file of each jboss I have defined the jvmRoute system property: <system-properties> <property name="jvmRoute" value="node1"/> </system-properties> At http:// localhost/myapp the application is accessible but the java-session is not build up correctly. Consequently the authentication is not working. The funny thing is, that everything is working if I turn off one JBoss-instance. As I have tried a couple of settings already, I am thankful for any further suggestions.

• Moodle serves on IP only - will not work with mod_proxy

  - by Jon H

  I'm trying to set a moodle server up on an Ubuntu box, which already serves Plone & Trac via Apache. In my Moodle config I have $CFG-wwwroot = 'http://www.server-name.org/moodle' The configuration below works fine for the first two, but when I visit www.server-name.com/moodle I get: Incorrect access detected, this server may be accessed only through "http://xxx.xxx.xxx.xxx:8888/moodle" address, sorry It then forwards to the IP address, where Moodle functions fine. What am I missing to get the server name approach working correctly? Apache Config follows: LoadModule transform_module /usr/lib/apache2/modules/mod_transform.so Listen 8080 Listen 8888 Include /etc/phpmyadmin/apache.conf <VirtualHost xxx.xxx.xxx.xxx:8080> <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPreserveHost On <Location /> ProxyPass http://127.0.0.1:8082/ ProxyPassReverse http://127.0.0.1:8082/ </Location> </VirtualHost> <VirtualHost xxx.xxx.xxx.xxx:80> ServerName www.server-name.org ServerAlias server-name.org ProxyRequests Off FilterDeclare MyStyle RESOURCE FilterProvider MyStyle XSLT resp=Content-Type $text/html TransformOptions +ApacheFS +HTML TransformCache /theme.xsl /home/web/webapps/plone/theme.xsl TransformSet /theme.xsl FilterChain MyStyle ProxyPass /issue-tracker !

• QNAP NAS 509 (LINUX) - how to unmout busy volume and find physical disk?

  - by Horst Walter

  On my NAS QNAP TS 509 I do have a technical issue. I need to run e2fsck. This works fine for me on md0 (see below), but how can I unmount the busy devices md9 and sda4 in order to do the same. Whenever I try, I fail because the device is busy. [This part is solved, see below] In order to further track down the issue, I'd need to sort out the physical disk to device relationship. How can I find out this, e.g. md0 is a stripped volume on 2 disk (but I need to find out on what physical disk). Remark: As you can easily derive from my questions, I am not a Linux expert, but manage to get along. /dev/ram0 124.0M 94.1M 29.8M 76% / tmpfs 32.0M 80.0k 31.9M 0% /tmp /dev/sda4 310.0M 103.9M 206.1M 34% /mnt/ext /dev/md9 509.5M 39.2M 470.2M 8% /mnt/HDA_ROOT /dev/md0 1.8T 1.4T 444.7G 76% /share/MD0_DATA tmpfs 32.0M 0 32.0M 0% /.eaccelerator.tmp -- Added -- QNAP seems to be based on Busybox. I do not find something like init / telinit / runlevel. At busybox docs it says that I need to run the below. But in /var/service sv is not available. I want to go to single user mode to unmount the devices. # cd /var/service # sv d * # sv u getty* -- Added, thanks A4L -- This QNAP Box runs a special flavor of Linux, so not all SOPs do apply. In my particular case I found a services.sh script, stopping all services. After that the drive could be unmounted. The information passed by A4L is valid and worth reading it, maybe I'll profit from it next time. Links: http://unix.stackexchange.com/questions/19918/umount-device-is-busy and http://unix.stackexchange.com/questions/15024/umount-device-is-busy-why So the unmount issue is solved, still looking for the best option to find the physical to volume mapping.

• Apache directive for authenticated users?

  - by Alex Leach

  Using Apache 2.2, I would like to use mod_rewrite to redirect un-authenticated users to use https, if they are on http.. Is there a directive or condition one can test for whether a user is (not) authenticated? For example, I could have set up the restricted /foo location on my server:- <Location "/foo/"> Order deny,allow # Deny everyone, until authenticated... Deny from all # Authentication mechanism AuthType Basic AuthName "Members only" # AuthBasicProvider ... # ... Other authentication stuff here. # Users must be valid. Require valid-user # Logged-in users authorised to view child URLs: Satisfy any # If not SSL, respond with HTTP-redirect RewriteCond ${HTTPS} off RewriteRule /foo/?(.*)$ https://${SERVER_NAME}/foo/$2 [R=301,L] # SSL enforcement. SSLOptions FakeBasicAuth StrictRequire SSLRequireSSL SSLRequire %{SSL_CIPHER_USEKEYSIZE} >= 128 </Location> The problem here is that every file, in every subfolder, will be encrypted. This is quite unnecessary, but I see no reason to disallow it. What I would like is the RewriteRule to only be triggered during authentication. If a user is already authorised to view a folder, then I don't want the RewriteRule to be triggered. Is this possible? EDIT: I am not using any front-end HTML here. This is only using Apache's built-in directory browsing interface and its in-built authentication mechanisms. My <Directory> config is: <Directory ~ "/foo/"> Order allow,deny Allow from all AllowOverride None Options +Indexes +FollowSymLinks +Includes +MultiViews IndexOptions +FancyIndexing IndexOptions +XHTML IndexOptions NameWidth=* IndexOptions +TrackModified IndexOptions +SuppressHTMLPreamble IndexOptions +FoldersFirst IndexOptions +IgnoreCase IndexOptions Type=text/html </Directory>

• Windows 7 hangs while loading desktop

  - by Joshua

  I am facing a weird problem. My computer hangs while loading the desktop, and only the background shows up; no icons or bars load. If I power the system on and off about 4-6 times, I may be able to use it normally. The desktop loads normally after rebooting or in safe mode; this only occurs when I start the system normally. I've tried several things to fix it, such as removing all start-up items, but it still doesn't solve the problem. What should I do? I found three major errors in Event Viewer: Source: Microsoft-Windows-DistributedCOM Level: Error DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server: {7D096C5F-AC08-4F1F-BEB7-5C22C517CE39} Source: Microsoft-Windows-DistributedCOM Level: Error DCOM got error "1084" attempting to start the service WSearch with arguments "" in order to run the server: {7D096C5F-AC08-4F1F-BEB7-5C22C517CE39} Source: Service Control Manager Level: Error The Network List Service service depends on the Network Location Awareness service which failed to start because of the following error: The dependency service or group failed to start.

• Apache Proxy Pass and Web Sockets

  - by James

  I'm using Apache with the mod_proxy module to reverse proxy my Node.js application through to port 80, so that we can access it as an internal application. I have a file in sites-enabled which contains this: VirtualHost *:80> DocumentRoot /var/www/internal/ ServerName internal ServerAlias internal <Directory /var/www/internal/public/> Options All AllowOverride All Order allow,deny Allow from all </Directory> ProxyRequests off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8080/ retry=0 ProxyPassReverse / http://localhost:8080/ ProxyPreserveHost on ProxyTimeout 1200 LogLevel debug AllowEncodedSlashes on </VirtualHost> As I said, our application is written in Node.js and we're using socket.io to make use of web-sockets, as our application also contains realtime elements to it. The problem is, mod_proxy doesn't seem to handle web sockets and we get errors when trying to use them: WebSocket connection to 'ws://bloot/socket.io/1/websocket/nHtTh6ZwQjSXlmI7UMua' failed: Unexpected response code: 502 How can we fix this issue and keep sockets working, as the only way we can get it working currently is to access the site via ip:port which we don't want to do. Also, as a side question, how can I get ErrorDocument to work properly? Our error files are stored in /var/www/internal/public/error/ but they seem to get put through the proxy too?

• Setting up subdomain to respond on :443 with apache2

  - by compucuke

  I read through some guides on this and I believe it is possible to have apache respond to a subdomain through ssl. I have domain.com responding on 80 and I do not need domain.com responding on 443. Rather, the only use I have for ssl is for the subdomain sub.domain.com. So my site should be http://domain.com http://www.domain.com https://sub.domain.com https://www.sub.domain.com My CNAME records are as follows sub.domain.com xxx.xx.xx.xxx *.sub.domain.com xxx.xx.xx.xxx The A record exists but should not matter for the example. I set up a separate config file in sites-enabled for sub.domain.com NameVirtualHost xxx.xx.xx.xxx:443 <VirtualHost xxx.xx.xx.xxx:443> SSLEngine on SSLStrictSNIVHostCheck on SSLProtocol -ALL +SSLv3 +TLSv1 SSLCipherSuite ALL:!aNULL:!ADH:!eNULL:!LOW:!EXP:RC4+RSA:+HIGH:-MEDIUM ServerAlias sub.domain.com DocumentRoot /usr/local/www/ssl/documents/ SSLCertificateFile /root/sub.domain.com.crt SSLCertificateKeyFile /root/sub.domain.com.key Alias /robots.txt /usr/local/www/ssl/documents/robots.txt Alias /favicon.ico /usr/local/www/ssl/documents/favicon.ico Alias /js/libs /usr/local/www/ssl/documents/js/libs Alias /media/ /usr/local/www/documents/media/ Alias /img/ /usr/local/www/ssl/documents/img/ Alias /css/ /usr/local/www/ssl/documents/css/ <Directory /usr/local/www/ssl/documents/> Order allow,deny Allow from all </Directory> WSGIDaemonProcess sub.domain.com processes=2 threads=7 display-name=%{GROUP} WSGIProcessGroup sub.domain.com WSGIScriptAlias / /usr/local/www/wsgi-scripts/script.wsgi <Directory /usr/local/www/wsgi-scripts> Order allow,deny Allow from all </Directory> </VirtualHost> Now, it is important to mention that https://domain.com responds with what I have running from script.wsgi above instead of on https://sub.domain.com. It does not respond to sub.domain.com. checking https://sub.domain.com causes a 105 error. This is a DNS error but I am convinced the DNS does not have a problem with the CNAME records, they just point to my IP. Am I doing something that Apache can not do?

  - by MICADO

  I have installed via synaptic package ibapache2-mod-perl2. I tried this line in httpd.conf: "LoadModule perl_module modules/mod_perl.so" Apache tells me when I reload the server : "[warn] module perl_module is already loaded, skipping". Well ok, but when i try to look in the browser to a repertory i don't have access .Apache send me the error : Forbidden You don't have permission to access /cgi-bin/ on this server.

• Mod_rewrite (CakePHP routing functionality) forbidden after Snow Leopard upgrade

  - by Ryan Ballantyne

  Hello ServerFault, I am using the standard Apple-provided installations of PHP 5.3 and Apache 2 to do web development on a Mac Pro that I just upgraded to Mac OS X 10.6 (Snow Leopard). The upgrade went well enough, if I ignore the fact that it destroyed my ability to get work done. ;) After the update, the CakePHP application I was developing started giving me 403 Forbidden errors when accessed. Based on the errors in the log file, I've determined that Apache is choking on the mod_rewrite rules in Cake's .htaccess file. Here's the file, in its entirety: <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] </IfModule> It's not that the rules themselves are wrong, but that Apache is forbidding the use of mod_rewrite altogether. All other pages on the machine work fine, and the 403 errors go away if I comment out the .htaccess file (but nothing works, of course). In my httpd.conf file, I've tried changing this: <Directory /> Options FollowSymLinks AllowOverride None Order deny,allow Deny from all </Directory> To this: <Directory /> Options FollowSymLinks AllowOverride All Order deny,allow Allow from all </Directory> ...which has no effect. I don't know much about Apache configuration files, and I'm quite stuck on this. In fact, I know little enough that I'm not sure which information about my setup is needed to enable people to provide useful answers. I'm just using the vanilla OS X setup, nothing fancy. Googling has yielded no fruits for me this time, so I'm turning to you. Any ideas?

• Enabling mod_rewrite on Amazon Linux

  - by L. De Leo

  I'm trying to enable mod_rewrite on an Amazon Linux instance. My Directory directives look like this: <Directory /> Order deny,allow Allow from all Options None AllowOverride None </Directory> <Directory "/var/www/vhosts"> Order allow,deny Allow from all Options None AllowOverride All </Directory> And then further down in httpd.conf I have the LoadModule directive: ... other modules... #LoadModule substitute_module modules/mod_substitute.so LoadModule rewrite_module modules/mod_rewrite.so #LoadModule proxy_module modules/mod_proxy.so ... other modules... I have commented out all the Apache modules not needed by Wordpress. Still when I issue http restart and then check the loaded modules with /usr/sbin/httpd -l I get only: [root@foobar]# /usr/sbin/httpd -l Compiled in modules: core.c prefork.c http_core.c mod_so.c Inside the virtual host containing the Wordpress site I have an .htaccess containing: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress The .htaccess is owned by apache which is the user apache runs under. The apachectl -t command returns Syntax OK What am I doing wrong? What should I check?

• Why does Windows 7 always automatically change the input or keyboard language?

  - by B-Ball

  I am wondering why Windows 7 always automatically changes my input or keyboard language. I've a notebook with an integrated QWERTY keyboard English (United States). Traveling, I use that one but, additionally, I've my own as well as a much better keyboard at home which is a QWERTZ keyboard German (Germany). Thus, being at home, I'd like to use my QWERTZ keyboard. Unfortunately, Windows 7 does not play along at this one. Every time, I start up my notebook, it is usually set to English (United States) but that's not the problem. In case, I'd use my notebook QWERTY keyboard English (United States), that's fine. However, if I start up my notebook and I'd like to use my QWERTZ keyboard German (Germany), I usually press ALT + Left Shift in order to switch from English (United States) to German (Germany) and Windows 7 switches the input language but only for the program that is currently open. If my input language is set to German (Germany) and I, e.g., open NotePad, Windows 7 automatically switches my input language to English (United States). This is very annoying since I've to change the input or keyboard language to German (Germany) every time I open up a new program. Why doesn't Windows 7 stay with one input language if I changed it manually by pressing ALT + Left Shift? Why doesn't the manual change of the input or keyboard language apply for the whole Windows 7? Why does it only affect the currently opened program? Since I've two keyboards with two different layouts, I seriously need to have both of the keyboards languages installed. I tried both of the below settings in order to find a solution for my problem. Currently, I am using the first option, two input languages. First option: two input languages: Second option: two keyboard languages:

• What folders to encrypt with EFS on Windows 7 laptop?

  - by Joe Schmoe

  Since I've been using my laptop more as a laptop recently (carrying it around) I am now evaluating my strategy to protect confidential information in case it is stolen. Keep in mind that my laptop is 6 years old (Lenovo T61 with 8 GB or RAM, 2GHz dual core CPU). It runs Windows 7 fine but it is no speedy demon. It doesn't support AES instruction set. I've been using TrueCrypt volume mounted on demand for really important stuff like financial statements forever. Nothing else is encrypted. I just finished my evaluation of EFS, Bitlocker and took a closer look at TrueCrypt again. I've come to conclusion that boot partition encryption via Bitlocker or TrueCrypt is not worth the hassle. I may decide in the future to use Bitlocker or TrueCrypt to encrypt one of the data volumes but at this point I intend to use EFS to encrypt parts of my hard drive that contain data that I wouldn't want exposed. The purpose of this post is to get your feedback about what folders should be encrypted from the general point of view (of course everyone will have something specific in addition) Here is what I thought of so far (will update if I think of something else): 1) AppData\Local\Microsoft\Outlook - Outlook files 2) AppData\Local\Thunderbird\Profiles and AppData\Roaming\Thunderbird\Profiles- Thunderbird profiles, not sure yet where exactly data is stored. 3) AppData\Roaming\Mozilla\Firefox\Profiles\djdsakdjh.default\bookmarkbackups - Firefox bookmark backup. Is there a separate location for "main" Firefox bookmark file? I haven't figured it out yet. 4) Bookmarks for Chrome (don't know where it's bookmarks are) and Internet Explorer ($Username\Favorites) - I don't really use them but why not to secure that as well. 5) Downloads\, My Documents\ and My Pictures\ folders I don't think I need to encrypt, say, latest service pack for Visual Studio. So I will probably create subfolder called "Secure" in all of these folders and set it to "Encrypted". Anything sensitive I will save in this folder. Any other suggestions? Again, this is from the point of view of your "regular office user".

• Laptop authentication/logon via accelerometer tilt, flip, and twist

  - by wonsungi

  Looking for another application/technology: A number of years ago, I read about a novel way to authenticate and log on to a laptop. The user simply had to hold the laptop in the air and execute a simple series of tilts and flips to the laptop. By logging accelerometer data, this creates a unique signature for the user. Even if an attacker watched and repeated the exact same motions, the attacker could not replicate the user's movements closely enough. I am looking for information about this technology again, but I can't find anything. It may have been an actual feature on a laptop, or it may have just been a research project. I think I read about it in a magazine like Wired. Does anyone have more information about authentication via unique accelerometer signatures? Here are the closest articles I have been able to find: Knock-based commands for your Linux laptop Shake Well Before Use: Authentication Based on Accelerometer Data[PDF] Inferring Identity using Accelerometers in Television Remote Controls User Evaluation of Lightweight User Authentication with a Single Tri-Axis Accelerometer Identifying Users of Portable Devices from Gait Pattern with Accelerometers[PDF] 3D Signature Biometrics Using Curvature Moments[PDF] MoViSign: A novel authentication mechanism using mobile virtual signatures

• reverse proxy not rewriting to https

  I need your help. I'm having problems with reverse proxy rewriting to https: I have an alfresco app running on top of tomcat and as a front and an Apache server - it's site-enabled looks like that: <VirtualHost *:80> ServerName alfresco JkMount /* ajp13_worker <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

• How can I set up Redmine => Active Directory authentication?

  - by Chris R

  First, I'm not an AD admin on site, but my manager has asked me to try to get my personal Redmine installation to integrate with ActiveDirectory in order to test-drive it for a larger-scale rollout. Our AD server is at host:port ims.example.com:389 and I have a user IMS/me. Right now, I also have a user me in Redmine using local authentication. I have created an ActiveDirectory LDAP authentication method in RedMine with the following parameters: Host: ims.example.com Port: 389 Base DN: cn=Users,dc=ims,dc=example,dc=com On-The-Fly User Creation: YES Login: sAMAccountName Firstname: givenName Lastname: sN Email: mail Testing this connection works just fine. I have, however, not successfully authenticated with it. I've created a backup admin user so that I can get back in to the me account if I break things, and then I've tried changing me to use the ActiveDirectory credentials. However, once I do, nothing works to log in. I have tried all of these login name options: me IMS/me IMS\me I've used my known Domain password, but no joy. So, what setting do I have wrong, or what information do I need to acquire in order to make this work?

• Setting up Red Hat Enterprise Linux Server as a mail exchange server

  - by Syedur

  I am a Unix/Linux/Windows Server noob. So, keep that in mind before you throw your stones at my glass house. :P I have a Windows Server 2008 R2 machine that's acting as domain controller, Server A. It's also running a DNS server. I have a Red Hat Enterprise Linux Server 5.3, Server B that is intended for mail server. In order for the mail delivery to happen, I understand that I have to set an MX record on Server A and point it to Server B. Well, I did. I manually added a host name on Server A and pointed to Server B's IP address. Then I added an MX record and pointed it to the host name. That didn't do the trick. After taking the above steps, I used the "dig" command on Server B to lookup the MX record coming back from Server A and it wasn't what I was expecting. What am I doing wrong here? I have noticed that... my Windows machines that are joined to the domain (Server A) are listed under the host names. The machines that are not joined to the domain are not list. This is fine, I am not worried about this. What does concern me, do I have to join the Server B to domain in order for Server A to recognize as a valid host and forward the MX properly? If so, some simple steps on how to join Server B to the domain would also help.

• 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 ''.

Suggestions on what could be going on to cause the Segmentation faults?

• 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.

• 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?

• 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.

• apache authentication

  - by veilig

  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? This is part of my apache's site-available file so far: <Directory /path/to/server/> Options Indexes FollowSymLinks -Multiviews Order Deny,Allow Deny from All Allow from 192.168 Allow from localhost Allow from domain1 Allow from domain2 AuthType Basic AuthName "my authentication" AuthUserFile /path/to/file Require valid-user Satisfy Any AllowOverride All <Files .htaccess> Order Allow,Deny Allow from All </Files> </Directory>
