= Services that worked fine yesterday suddenly don't work anymore =
The most likely reason for IMAP, DNS, and web hosting to suddenly stop working is that there is a syntax error in one of the files in your {{{~/.domtool}}} directory.  Admins sometimes need to regenerate all domtool configuration files after making a change to domtool; if one of the files in your {{{~/.domtool}}} directory has errors, it could prevent other files in that directory from being activated.

To figure out whether this was the problem: for each file '''<FILE>''' in your {{{~/.domtool}}} directory, run

{{{
domtool -tc ~/.domtool/<FILE>
}}}
If you see any problems, either move the file into a different directory, or fix the problems.

When done, run '''domtool''' on each file in your {{{~/.domtool}}} directory, and everything should be back to normal.

It is highly recommended to keep files in a different directory while testing them, and then copy them to {{{~/.domtool}}} once you are certain that they are error-free.

If you don't find any errors in your domtool configuration, then you might want to file a support request.

= How do I read my Apache logs? =
They are stored in {{{~/.logs/apache}}} in subdirectories corresponding to machine and domain, and are updated every 20 minutes.

= How do I run screen for a long time on mire? =
If you want to have a long-running {{{screen}}} session and avoid permission denied errors, then log into mire and do the following:

{{{
screen
kinit -l 10d
krenew -K 540 -t -b
}}}
This will last until the ticket can no longer be renewed (approximately 8 days).  However, you can kinit and krenew again while in the screen session to restart the clock.  If the ticket expires while in a screen session, then you need to repeat those steps while in screen but be sure to add `aklog` for AFS ticket.  You do not have to restart the screen session.  In fact, you can dedicate a screen window just for monitoring and using kinit, aklog, and krenew. With this simple method, your screen session can run indefinitely with minimal weekly input.
