[olug] Reduce Directory Size

[Vincent]

Are you using logrotate?  Logrotate (properly configured) will cycle out old data and gzip them if you want.
For compression, I would prefer to let the kernel (ext# filesystems) handle it so I don't have to manually uncompress old files to
view them.  Check out the "c" option in the chattr/ lsattr man pages.

Here's an example of how I make sshd log separately and rotate the log files with logrotate:
[user at host ~] cat /etc/logrotate.conf
# rotate log files weekly
weekly
# keep 12 weeks worth of backlogs
rotate 12
# create new (empty) log files after rotating old ones
create
# uncomment this if you want your log files compressed
#compress
# RPM packages drop log rotation information into this directory
include /etc/logrotate.d
# no packages own wtmp -- we'll rotate them here
/var/log/wtmp {
    monthly
    create 0664 root utmp
    rotate 1
}

[user at host ~] cat /etc/logrotate.d/sshd
/var/log/sshd {
    missingok
    notifempty
    sharedscripts
    postrotate
        /bin/kill -HUP `cat /var/run/sshd.pid 2>/dev/null` 2> /dev/null || true
    endscript
}

[user at host ~] grep LOCAL6 /etc/ssh/sshd_config:
SyslogFacility LOCAL6

[user at host ~] grep LOCAL6 /etc/syslog.conf:
local6.*;auth.*;authpriv.*                              /var/log/sshd
