how do you configure rotation of syslog log files on ubuntu?
in my /etc/syslog.conf, i have this line:
local1.* /var/log/log.txt
over time, the following backup files have appeared:
/var/log/log.txt.0.gz /var/log/log.txt.1.gz
how do i configure how often these files get generated, and how to clean them out?
