During Debian installation, I set my hostname to the wrong value, and now I would like to correct that.

The hostname is stored in three different files:
/etc/hostname
Used as the hostname/etc/hosts
Helps resolving the hostname to an IP address/etc/mailname
Determines the hostname the mail server identifies itself
You might want to have a deeper look with grep -ir hostname /etc
Restarting affected services might be a good idea as well.
The value is stored in /etc/hostname
. After modifying, apply it with /etc/init.d/hostname start

Various services may also depend on being able to resolve the hostname locally, which is often handled by an entry in the /etc/hosts file.
