Check Logfiles
From MEPIS Documentation Wiki
A quick check of kernel messages is given by the command
dmesg
or
dmesg | tail
for a shorter version that lists the most recent log entries.
Various systems logs can be found in
/var/log
You must examine these text files as root. Some important ones are
- auth.log See how, when, and who has been logging onto your system
- kern.log Log of kernel messages.
- messages Repeat of auth.log, cron, mail
Other files containing *.0 or *.1.gz, *.2.gz, ... are rolling archives of the log.
