Getting Started with Citadel

Timothy J Bruce — Wed, 22 Apr 2009 02:27:00 GMT

The appliance obtains its IP via DHCP. The virtual console will display it at the top of the screen:

Citadel virtual appliance - (C) 2007 http://www.citadel.org
To log in to Citadel, point your web browser to http://192.168.1.22

Simply point your web browser there and get started. The default administraor has the username Citadel and password citadel. Obviously you will want to change the default once you log in. After you have logged in once with webcit, you can connect to that account with your favorite mail client via POP, IMAP or SMTP. A more thorough Getting Started may give you aditional information.

Plugins for Squirrel Mail

Timothy J Bruce — Tue, 13 May 2008 02:03:00 GMT

Adding a Squirrelmail plugin is relatively simple. This sample installs the "change_sqlpass" plugin (which requires the "compat" (or compatibility) plugin. First copy the necessary plugins to the server you are installing them onto. A command like:

$ scp plugin timbruce@server:~/download/squirrelmail

Depending on how it's installed, you need to assume the correct user to configure the plugin.

$ sudo su -

On Ubuntu, you need to change to the following directory:

# cd /usr/share/squirrelmail/plugins

Then execute the following command:

# tar -xzvf compatibility-2.0.9-1.0.tar.gz
# tar -xzvf change_sqlpass-3.3-1.2.tar.gz

Detemine which version of SquirrelMail you are running (looking at the login page will help). I'm using Ubuntu version 1.4.10a, so I patch using v1.4. Now I can install compatibility using the following command:

# cd /usr/share/squirrelmail/plugins/compatibility/
# patch -p0 < patches/compatibility_patch-1.4.10.diff

After this, configure SquirrelMail.

# cd ../config
# ./conf.pl

Go to #8 (Plugins) and install change_sqlpass. (NOTE: I also need to update the plugins/change_sqlpass/config.php file with the appropriate parameters to allow it to update the database.)

Enjoy

Possible K3B Issue(s)

Timothy J Bruce — Fri, 01 Jun 2007 05:32:00 GMT

I recently ran into a problem where I was unable to successfully burn a DVD (Digital Video Disk) .ISO file. (NOTE: Some documentation may refer to a DVD as a Digital Versatile Disk instead of a Digital Video Disk. Both are correct. The term Digital Video Disk is more commonly used because it is the format for watching movies.) For those who may not be aware, an .ISO file is an image of a data CD (Compact Disk) or DVD.

At any point, multiple burns of the same image (.ISO) on different computers with different DVD writers all resulted in the same failure. Even though K3B reported the burn (creation of the new DVD) as successful, I was not able to use the DVD successfully in another system. I was able to verify the issue by using a program called md5sum that generates a unique identifier based upon the contents of the DVD (or files) it is checking. The MD5SUM (the number) for the original download did not match the number for the new DVD on any one of the 5 copies I created. In effect, these failures caused me to burn "coasters" (since that was all the DVDs were good for). Looking at some other websites, I was able to piece some information together. While the documentation is sporadic, and this error may be unique to creating DVDs, I found that using the following options in K3B allowed me to successfully. I added the options to the growisofs command: -use-the-force-luke=dao -dvd-compat Hopefully this will solve anyone elses issues. And as I get more information, I'll try to update this page.
