Hi Anne.

Craig gave you the right places to look, but to answer your original
question ...

This will find all ext3 files on your system and search them
for your hostname and print out the file names that contain it.

As root:

# find / -type f -fstype ext3 -exec fgrep -l "hostname" {} \;

It will take some time.

You can play various games with find's commandline args to exclude
certain directories, do conditional searches, limit the search to a
particular filesystem, &c.

Worth spending the time studying its man page. One of the most useful
commands in unix-dom.

Don't use your fully qualified hostname unless your system name is
some really common or short name.  Sometimes it appears in system
files unqualified.


P.S. As you can see from previous e-mail, I'm finally running FC-5
     Thanks for directing me here those many months ago. :-)
