Apache2.2 not responding on Windows 7 desktop

- by Adam

Afternoon! I'm having some trouble with Apache2.2 on Windows 7. For over a year it's been running no problem, but all of a sudden requests have just stopped responding. They don't ever time out, the browser just keeps on waiting for a response, which makes me think it's something blocking communication with Apache. Interestingly though, if I stop Apache the requests fail immediately. The Apache service is running, and using netstat I can see it listening on port 80 as configured: TCP 127.0.0.1:80 0.0.0.0:0 LISTENING If I stop the Apache service, that line disappears. I have an entry within my hosts file for each VHost I'm trying, all pointing to 127.0.0.1. Each VHost is configured to *:80. Nothing however is getting recorded in the access or error (at debug level) log files. I've verified the file paths are correct, even though they were never changed. Neither is anything getting recorded within Windows' Event Log. The problem showed up when I added a new VHost and restarted, however I hadn't been using it for a couple of days prior so I don't believe it's the config change. I have performed a syntax check to be sure, and when starting from the command prompt no errors are reported there. I do have Windows Firewall running, however I've verified the Apache rule is correct and tried turning it off to ensure that wasn't the problem. I've reinstalled Apache, in the hope it might magically fix something using the default config, but still no joy. I've also tried using a different port. I'm completely lost for ideas now. Can anybody help? Cheers Adam

FTP Server on Centos 5.8 - Transfer fails randomly

- by Diego

Hi have ProFTPD runningon a brand new CentOS 5.8 server with Plesk, and its behaviour is inconsistent at best. I tried to transfer a directory from my PC, and every time I get a transfer failed on a random file. It's never the same one that fails, it just fails. Sometimes it's a .gif, sometimes it's a .css, sometimes it's a JPG. Of several hundred files, a dozen is always failing for no apparent reason. The error that I get is the following: COMMAND:> [27/11/2012 11:43:52] STOR main_border.gif [27/11/2012 11:43:53] 500 Invalid command: try being more creative ERROR:> [27/11/2012 11:43:53] Syntax error: command unrecognized. The above is just an example, the "command unrecognized" occurs with LIST and other commands as well. Here's the ProFTPD configuration, just in case: ServerName "ProFTPD" #ServerType standalone ServerType inetd DefaultServer on <Global> DefaultRoot ~ psacln AllowOverwrite on </Global> DefaultTransferMode binary UseFtpUsers on TimesGMT off SetEnv TZ :/etc/localtime Port 21 Umask 022 MaxInstances 30 ScoreboardFile /var/run/proftpd/scoreboard TransferLog /usr/local/psa/var/log/xferlog #Change default group for new files and directories in vhosts dir to psacln <Directory /var/www/vhosts> GroupOwner psacln </Directory> # Enable PAM authentication AuthPAM on AuthPAMConfig proftpd IdentLookups off UseReverseDNS off AuthGroupFile /etc/group Include /etc/proftpd.include Note: file /etc/proftpd.include is blank. The above is the default configuration set by Plesk 11. I don't know much of why is that way, my knowledge of Linux System Administration is very basic and the one of ProFTPD is a complete zero. Thanks in advance for the help. Update Issue experienced with CuteFTP and FileZilla. Update Replaced ProFTPd with PureFTPd, issue persists. Sometimes I get "command unrecognized", sometimes "failed to establish data connection". I'm starting to think that it could be a network issue, but I have completely zero knowledge of networking.

Cacti is ignoring hash marks in interface aliases

- by Matt Simmons

I'm attempting to set up Cacti to monitor a router's interfaces, and I'm having trouble getting the graph templates to show the information that I'd like. Our interface configuration looks like this: interface GigabitEthernet3/6 description WalljackNumber # Server info no ip address no shutdown switchport switchport access vlan 116 switchport mode access ip dhcp snooping trust spanning-tree portfast The "Server Info" string is really just the machine name, and a short relevant description, such as "PolarSprings vmnic2". The important part appears to be that it follows the hashmark. When I run snmpwalk, I get the proper output: IF-MIB::ifAlias.230 = STRING: WalljackNumber # Server info But in Cacti, when I go into the graph templates and set the title to this: |host_description| - Traffic - |query_ifName| (|query_ifAlias|) All that shows up in the graph is: switchname - Traffic - Gi3/6 (WalljackNumber #) Which strikes me as a little weird. What I suppose MAY be happening is that somewhere in the cacti stream, it's interpreting # as being a comment and stripping everything after, but I'm not sure. I was hoping someone could tell me that this was a known documented behavior, or that I could change it in a setting that I wasn't aware of. The alternative answer is to change the delimiter from # to something else, but I've got over a thousand lit switchports on an old college infrastructure, and I'm not sure what else might be relying on them.

Why is SMF manifest losing configuration data when exported on SmartOS?

- by Scott Lowe

I'm running a server process under SMF (Server Management Facility) on Joyent's Base64 1.8.1 SmartOS image. For those not aqauinted with SmartOS, it is a cloud-based distribution of IllumOS with KVM. But essentially it is like Solaris and inherits from OpenSolaris. So even if you've not used SmartOS, I'm hoping to tap into some Solaris knowledge on ServerFault. My issue is that I want an unprivileged user to be allowed to restart a service that they own. I have worked out how to do that by using RBAC and adding an authorisation to /etc/security/auth_attr and associating that authorisation with my user. I then added the following to my SMF manifest for the service: <property_group name='general' type='framework'>  <propval name='action_authorization' type='astring' value='solaris.smf.manage.my-server-process' />  <propval name='value_authorization' type='astring' value='solaris.smf.manage.my-server-process' /> </property_group> And this works well when imported. My unprivileged user is allowed to restart, start and stop its own server process (this is for automated code deployments). However, if I export the SMF manifest, this configuration data is gone... all I see in that section is this: <property_group name='general' type='framework'> <property name='action_authorization' type='astring'/> <property name='value_authorization' type='astring'/> </property_group> Does anybody know why this is happening? Is my syntax wrong, or am I simply not using SMF incorrectly?

Need Corrected htaccess File

- by Vince Kronlein

I'm attempting to use a wordpress plugin called WP Fast Cache which creates static html files from all your posts, pages and categories. It creates the following directory structure inside wp-content: wp_fast_cache example.com pagename index.html categoryname postname index.html basically just a nested directory structure and a final index.html for each item. But the htaccess edits it makes are crazy. #start_wp_fast_cache - do not remove this comment <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_METHOD} ^(GET) RewriteCond /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}x__query__x%{QUERY_STRING}index.html -f RewriteCond %{HTTP_USER_AGENT} !(iPhone|Windows\sCE|BlackBerry|NetFront|Opera\sMini|Palm\sOS|Blazer|Elaine|^WAP.*$|Plucker|AvantGo|Nokia) RewriteCond %{HTTP_COOKIE} !(wordpress_logged_in) [NC] RewriteRule ^(.*)$ /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}x__query__x%{QUERY_STRING}index.html [L] RewriteCond %{REQUEST_METHOD} ^(GET) RewriteCond %{QUERY_STRING} ^$ RewriteCond /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}index.html -f RewriteCond %{HTTP_USER_AGENT} !(iPhone|Windows\sCE|BlackBerry|NetFront|Opera\sMini|Palm\sOS|Blazer|Elaine|^WAP.*$|Plucker|AvantGo|Nokia) RewriteCond %{HTTP_COOKIE} !(wordpress_logged_in) [NC] RewriteRule ^(.*)$ /home/user/public_html/wp-content/wp_fast_cache/%{HTTP_HOST}%{REQUEST_URI}index.html [L] </IfModule> #end_wp_fast_cache No matter how I try and work this out I get a 404 not found. And not the Wordpress 404, and janky apache 404. I need to find the correct syntax to route all requests that don't exist ie: files or directories to: wp-content/wp_fast_cache/hostname/request_uri/ So for example: Page: example.com/about-us/ => wp-content/wp_page_cache/example.com/about-us/index.html Post: example.com/my-category/my-awesome-post/ => wp-content/wp_fast_cache/example.com/my-category/my-awesome-post/index.html Category: example.com/news/ => wp-content/wp_fast_cache/example.com/news/index.html Any help is appreciated.

Speakers silent, headphones work in Ubuntu 9.04

- by CarlF

I'm running Ubuntu 9.04. Worked fine for months, then I rebooted yesterday after weeks of continuous operation. Now audio won't play through the speakers. The USB headset works fine, but the Conexant audio (CX20549) does not. Weirdly, it thinks it's playing. pavumeter shows appropriate levels, volume looks OK in alsamixer, but no sound. I did find this page: http://www.eugeneteplitsky.com/fixing-silent-pulseaudio-in-ubuntu-9-04/ Unfortunately the advice there doesn't help me. For one thing, the syntax for the alsa-base.conf file is apparently not actually documented anywhere. For another, my chipset isn't listed in the kernel.org docs he links to! EDIT: would upgrading to 9.10 help? Is there a major change in the audio subsystem between 9.04 and 9.10? Any suggestions? EDIT 2: This is stranger than I thought. Sound works normally in Xine, but is silent in Audacity, VLC and mplayer. What the?

Do you known a reputable backup software that can capture ONLY file system structure + attributes, WITHOUT file content

- by bogdan

Is there, on Windows, a reputable backup software out there capable of capturing ONLY a file system's directory and file structure, along with each item's attributes, WITHOUT capturing the actual file content (all files should be zero-length in the backup). I thoroughly searched the web for a solution and wasn't able to find one. Scenario when this would be very useful: I have a large drive with a huge amount of files. If the drive dies, I don't care so much about the content in these files (I can always download this content again from the Internet at any time) but I do care HUGELY about the names of the files that were on it, possibly also about their MD5 hashes and other classic file attributes (especially created-date / modified-date). The functionality I need is present to an extent in "media"/file cataloging software (i.e. whereisit) and, to a lesser extent, in a Total Commander set of extensions (DiskDir, DiskDirExtended). The huge drawback with cataloging software is that it's not designed to store previous versions of each item (AFAIK) and, most importantly, it has very weak content backup capabilities. I managed to think of a hack but I hope there's some backup software out there that already has this capability and I just failed to find it, thus this question. The hack: RoboCopy could be used with /CREATE (CREATE directory tree and zero-length files only) or /COPY (what to COPY for files) without the D=Data flag, to clone a directory structure into one where all files are zero-length but have the desired attributes. Then I would backup the cloned directory structure with a reputable backup software. I would really love to avoid a hack like this one, if possible. Thanks, Bogdan

Excel concatenate strings from cells listed in third cell

- by Puddingfox

I have an excel 2007 workbook that has five columns: A. A list of machines B. A list of service numbers for each machine C. A list of service names for each machine ...(nothing here) I. A list of Service Numbers J. A list of Service Names Each machine listed in column A has one or more services running on it from the list in column J. I would like to be able to add services to a machine (i.e. updating the cell in Column C) by simply adding another comma-separated number to Column B. For Example, The first row would look like this assuming Machine1 has the first three services: | A | B | C | Machine1 | 1,2,3 | HTTP,HTTPS,DNS Right now I have to manually update the formula in column c for each change I make. The current formula is: =CONCATENATE(J1,",",J2,",",J3) I would like to use something like this (please forgive my syntax; I'm a coder and I'm treating cell B1 as if it is an indexed array): =CONCATENATE(CELL("J"+B1[0] , "," , "J"+B1[1] , "," "J"+B1[2]) Although having variable numbers of services makes this even more difficult. Is there any way of doing this. For reference, this is columns I and J: | I | J | 1 |HTTP | 2 |HTTPS | 3 |DNS ..... | 16 |Service16 I don't know very much about Excel so any help is greatly appreciated.

Thundrbird 3: can't change column width?

- by rumtscho

I recently installed Thunderbird 3.0.3. Just noticed a suboptimal UI setting: in the upper pane, which lists the e-mails in the current folder, the Date column is about 200px wide. So when I keep the window at 480x600, all I see in a row is: | tree icon | favourites icon | attachment icon | read icon | junk icon | Date and time, followed by 5cm whitespace | ... | P Where "P" is the first letter of the name of the sender. And the "..." is actually shown this way, I have no idea which column it is meant to be. But I don't see neither the sender, nor the message subject, which makes scrolling a folder for a certain mail rather pointless. I see these when I maximize the window, actually the columns are then not only bigger, they are arranged in another sequence. But I feel that holding a mail client permanently maximised at 1600x1200 is a waste of screen real estate. My naive solution attempt was to try to go with the mouse cursor to the right edge of the date column and try to shrink it by moving the cursor left while holding down the left mouse button. Not only is this default behaviour for all resizable columns I've ever encountered in GUIs, the cursor actually turns into a horizontal double-headed arrow. But pulling has no effect at all. I cannot make a wide column narrow, and I cannot make the narrow columns wide. I didn't find anything in the preferences either. So can please somebody explain how to get the columns arranged sensibly?

Underbraces in Word math zones and dealing with stretchy parentheses

- by Johannes Rössel

Parentheses in Word usually stretch with whatever they're containing. This might be un-noticeable for things like but for stuff like it's definitely nice, especially compared to the fact that naïve LaTeX users often produce uglinesses such as There is a problem, however, when using under-/overbraces in math and putting parentheses around the complete term it becomes ugly. For simple things like shown here this can be solved by not letting the parentheses stretch which looks almost right. However, for more complex things it's certainly not an option: Both variants look horrible. So is there a way of letting the parentheses only stretch around the actual term parts, not including the under-/overbraces? Those are frequently used for annotations of individual pieces, so simply not using them is a bad idea too. In LaTeX you can get away with guesswork and using explicit sizes for the parentheses instead of relying on \left and \right but I haven't found a comparable option in Word yet. Since the underbrace is (tree-wise) a sibling of the term in parentheses it probably simply has to stretch and there probably can't be an algorithm that determines when to stretch or when not, considering that \above and \below are used for annotations as well but also for other things where perentheses have to stretch. Also, since the parenthesized expression is opaque from the outside one has to put the underbrace inside. From a markup point of view, at least. One can probably draw the rest around but that falls apart when styles change and wouldn't be a good idea either.

Excel 2007 pivot table does not aggregate properly

- by Patrick

I am using a an excel pivot table to summarize some data and just found a problem. The problem deals with how aggregate values are calculated. Let's say I have a table of data with three columns: Name, Date, Value. If I create a table where Name and then Date are used as Row Labels and Value is the aggregate value, ie Average. The pivot table will look something like this: +John .3450 5/14/2010 1.234 5/15/2010 3.450 5/16/2010 -3.25 What I think should be happening here is that the values for each date are averaged and then those values are averaged to come up with the value in the same row as the Name, John. But that is not what it does. It takes the average for each date, which it shows across from the date, but then instead of taking the average of those numbers, it actually uses the raw data and computes the average for all of John's values. It should show the average of the daily averages to correspond with the tree hierarchy, but instead just shows me the average for all of John's values. It essential will only aggregate at one level, but visually creates sub levels that it is not using. Does anyone know how to change this or understand by what logic this makes sense? Why would I create any sub groupings if I cannot compute aggregates on them?

A star vs internet routing pathfinding

- by alan2here

In many respects pathfinding algorythms like A star for finding the shortest route though graphs are similar to the pathfinding on the internet when routing trafic. However the pathfinding routers perform seem to have remarkable properties. As I understand it: It's very perfromant. New nodes can be added at any time that use a free address from a finite (not tree like) address space. It's real routing, like A*, theres never any doubling back for example. IP addresses don't have to be geographicly nearby. The network reacts quickly to changes to the networks shape, for example if a line is down. Routers share information and it takes time for new IP's to be registered everywhere, but presumably every router dosn't have to store a list of all the addresses each of it's directions leads most directly to. I can't find this information elsewhere however I don't know where to look or what search tearms to use. I'm looking for a basic, general, high level description to the algorithms workings, from the point of view of an individual router.

What is /etc/apache2/sites-available used for and is it necessary?

- by Mariane

I have 3 sites, each with a specific IP, running on apache2 (up-to-date Ubuntu). To put a site online, I just created a file in: /etc/apache2/sites-enabled and in this file I told apache which directory was the root directory for this site, and to which IP it should correspond. So I have 000-default 001-www.lapf.eu 002-www.felkin.info 003-www.seidhr.fr in this directory. My first site, lapf suddenly lost contact with its database after the domain name was transferred from another registrar unto the registrar who is also hosting the site's data. Then I did an update, and I reinstalled mysql-server and mysql-common, and I did I-have-forgotten-what to reinstall the locales (uft8 and such) which had vanished for some reason. This fixed my first site. Now I noticed that the other 2 sites are offline. Pointing a browser to them just hangs until timeout. They used to function, and their domain names did not move, they are still registered at the same place. The files are still in /etc/apache2/sites-enabled I noticed another directory: /etc/apache2/sites-available with just defaut and default.ssl in it. Why are there 2 directories, sites-enabled and sites-available? Should I copy the files from "sites-enabled" into "sites-available"? Or should I put a modified version of each in "sites-available"? command: "apache2ctl -S" VirtualHost configuration: 92.243.20.169:80 Charlotte (/etc/apache2/sites-enabled/001-www.lapf.eu:1) 92.243.21.141:80 xvm-21-141.ghst.net (/etc/apache2/sites-enabled/002-www.felkin.info:1) 92.243.4.114:80 xvm-4-114.ghst.net (/etc/apache2/sites-enabled/003-www.seidhr.fr:1) wildcard NameVirtualHosts and default servers: *:80 is a NameVirtualHost default server Charlotte (/etc/apache2/sites-enabled/000-default:1) port 80 namevhost Charlotte (/etc/apache2/sites-enabled/000-default:1) Syntax OK

knife on Windows inconsistently reads ~\.ssh\knife.rb on Management Workstation

- by gWaldo

I am implementing a new instance of (Open-source v10.12) Chef in an existing environment. Currently the environment is mostly Windows, but more Linux is being introduced. I have used Chef in a previous gig, however that was a *nix-only environment. Because this is a primarily-Windows environment, my main workstation is Windows 7 (x64), and I use Powershell as my main terminal. I created a ~\.chef directory, populated with a knife.rb and my client.pem file. When I run knife client list from ~, I get the expected results. I keep my work in Dropbox just in case my laptop should fail or be stolen. When I run knife client list from the repo directory (C:\Users\waldo\Dropbox_company\projects\chef`), I get ERROR: Your private key could not be loaded from C:/home/waldo/.chef/waldog.pem Check your configuration file and ensure that your private key is readable (Note that the path is incorrect) This is the progression as I walk up the tree towards my ~ running knife client list: C:\Users\waldo\Dropbox\_company\projects\ => Above error C:\Users\waldo\Dropbox\_company\ => Above error C:\Users\waldo\Dropbox\ => It works! (Expected results) C:\Users\waldo\ => Expected results C:\Users\waldo\Documents\ => Expected Results C:\Users\waldo\Documents\GitHub => Expected Results C:\Users\waldo\Documents\GitHub\aProject\ => Expected Results What. The. Eff! Now, I know that I can add -c path\to\knife.rb, but that's a HUGE PITA. Question is: Why is knife inconsistently reading my ~\.chef\knife.rb, and how can I get around that without incurring carpal tunnel?

I am reading the instructions on conkeror site (and elsewhere) on how to install conkeror on Ubuntu (I am using Ubuntu 12_04 LTS) and it seems that the correct sequence is: sudo apt-add-repository ppa:xtaran/conkeror sudo apt-get update sudo apt-get install conkeror conkeror-spawn-process-helper The first step (apt-add-repository) seems to execute without a problem, giving the following output: You are about to add the following PPA to your system: Conkeror Debian packages for Ubuntu releases without xulrunner (i.e. for 11.04 Natty and later) More info: https://launchpad.net/~xtaran/+archive/conkeror Press [ENTER] to continue or ctrl-c to cancel adding it Executing: gpg --ignore-time-conflict --no-options --no-default-keyring --secret- keyring /tmp/tmp.Re7pWaDEQF --trustdb-name /etc/apt/trustdb.gpg --keyring /etc/apt/trusted.gpg --primary-keyring /etc/apt/trusted.gpg --keyserver hkp://keyserver.ubuntu.com:80/ --recv CB29CBE050EB1F371BAB6FE83BE0F86A6D689050 gpg: requesting key 6D689050 from hkp server keyserver.ubuntu.com gpg: key 6D689050: "Launchpad PPA for Axel Beckert" not changed gpg: Total number processed: 1 gpg: unchanged: 1 However, the apt-get update seems unable to fetch packages from the newly added PPA, with its output ending in: Hit http://security.ubuntu.com precise-security/restricted Translation-en Hit http://security.ubuntu.com precise-security/universe Translation-en Err http://ppa.launchpad.net precise/main Sources 404 Not Found Ign http://extras.ubuntu.com precise/main Translation-en_US Err http://ppa.launchpad.net precise/main i386 Packages 404 Not Found Ign http://extras.ubuntu.com precise/main Translation-en Ign http://ppa.launchpad.net precise/main Translation-en_US Ign http://ppa.launchpad.net precise/main Translation-en W: Failed to fetch http://ppa.launchpad.net/xtaran/conkeror/ubuntu/dists/precise /main/source/Sources 404 Not Found W: Failed to fetch http://ppa.launchpad.net/xtaran/conkeror/ubuntu/dists/precise/main/binary-i386/Packages 404 Not Found E: Some index files failed to download.

What do the readonly attributes in diskpart really mean?

- by marzipan

I am wondering exactly what the meaning is of the "Read-only" disk and volume attributes that you can twiddle in diskpart on Windows 7. I am trying to set up an external USB drive as an installation medium for my own software, so I'd like to protect it against casual or inadvertent changes by users who it is given to, so they don't screw up the installation files they might need in the future. From what I can tell by experimentation with diskpart, the volume read-only attribute is actually stored on the physical disk somewhere, because I can set it and it shows up when I take the drive to another machine. This is great because my users can't (easily) change any of the files on the volume, or format it from Windows explorer. However, the disk read-only attribute seems to be just an aspect of how the current machine is accessing the drive. When I set it I can no longer delete the volume in the disk via Disk Management, but when I take the drive to another machine, the attribute is no longer set and in Disk Management I can delete the volume on the disk. I guess I'm not that worried about my users doing that, but I am annoyed that I don't understand what these attributes are really doing. Another thing that I don't understand is that the "volume" read-only attribute actually seems to be global to the disk - if I have two volumes on the disk, and I set the readonly flag on one of them, then it gets set on the other one too. ?!? I have the feeling I'm not searching for the right docs - all I'm finding is diskpart docs that give the syntax for twiddling these attributes, not what they really mean. Any pointers would be very welcome! Thanks, Asa

Underbraces in Word math zones and dealing with parentheses

- by Johannes Rössel

Parentheses in Word usually stretch with whatever they're containing. This might be un-noticeable for things like but for stuff like it's definitely nice, especially compared to the fact that naïve LaTeX users often produce uglinesses such as There is a problem, however, when using under-/overbraces in math and putting parentheses around the complete term it becomes ugly. For simple things like shown here this can be solved by not letting the parentheses stretch which looks almost right. However, for more complex things it's certainly not an option: Both variants look horrible. So is there a way of letting the parentheses only stretch around the actual term parts, not including the under-/overbraces? Those are frequently used for annotations of individual pieces, so simply not using them is a bad idea too. In LaTeX you can get away with guesswork and using explicit sizes for the parentheses instead of relying on \left and \right but I haven't found a comparable option in Word yet. Since the underbrace is (tree-wise) a sibling of the term in parentheses it probably simply has to stretch and there probably can't be an algorithm that determines when to stretch or when not, considering that \above and \below are used for annotations as well but also for other things where perentheses have to stretch. Also, since the parenthesized expression is opaque from the outside one has to put the underbrace inside. From a markup point of view, at least. One can probably draw the rest around but that falls apart when styles change and wouldn't be a good idea either.

chkconfig creating service symlinks with the wrong order

- by Robert

On RHEL 6.3, I have a system service that should be starting after postgresql and httpd (order 64 and 85, respectively), but chkconfig always places it at order 50. I tried an experiment on a CentOS 6.0 virtual machine to make sure I understood the LSB stanza syntax. I created /etc/init.d/foo, owner root, permissions 755, with this text: ### BEGIN INIT INFO # Provides: foo # Required-Start: postgresql httpd # Default-Start: 2 3 4 5 # Default-Stop: 0 1 6 # Description: Foo init script ### END INIT INFO And then ran chkconfig --add foo. Result: /etc/rc5.d/S86foo is created, as expected. (The other runlevels are also as expected.) I repeated the exact same experiment on the RHEL machine, and it created /etc/rc5.d/S50foo instead. I can't see anything different between the two that would lead to different results. Both machines have postgresql and httpd starting at the same orders and runlevels. Any thoughts? I could just use # chkconfig: 2345 86 50, or manually rename the service symlinks to the correct order, but I'm trying to document an install process for later users, and I want to know how to do it right and understand why it's not working as expected.

Mindtouch broke my Apache2 virtual host configuration.

- by grenade

I installed mindtouch using the instructions here and it seems to have broken my Virtual Host configuration. I have several domains running off the same apache instance and this was working fine but now all my domain names resolve to the virtualhost where mindtouch was installed. So mindtouch made all my domain names point to the new mindtouch instance. Grrr! I use debians default virtual host mechanisms (sites-enabled, etc). Does anyone know what apache directive mindtouch is using to ruin my vh setup? I've scoured all the conf files and there is nothing obvious in apache2.conf or httpd.conf that would cause the behaviour. Did it create a sym-link somewhere that I should destroy? I should add that I uninstalled the mindtouch packages already but apache persists in redirecting all domains to the first one mentioned in the sites-enabled folder. thini:~# apache2ctl -S [Wed Jan 05 13:39:11 2011] [warn] NameVirtualHost *:80 has no VirtualHosts VirtualHost configuration: wildcard NameVirtualHosts and _default_ servers: *:* www.openancestry.org (/etc/apache2/sites-enabled/openancestry.org:1) *:* www.pragmantra.com (/etc/apache2/sites-enabled/pragmantra.com:1) *:* services.pragmantra.com (/etc/apache2/sites-enabled/services.pragmantra.com:1) *:* www.subversionreports.com (/etc/apache2/sites-enabled/subversionreports.com:1) *:* www.thijssen.ch (/etc/apache2/sites-enabled/thijssen.ch:1) Syntax OK
