I am a newly hired Net Admin and the IPCop firewall was installed and implemented by a previous IT guy who left the company. I haven't had experience on Linux firewall before so before thinking of upgrading, want to know if I need to be alarmed on the disk usage of our firewall?
Your /dev/root seems to be pretty full. Check your "/" folder to see if there are ISOs or other such files stored there. You would normally expect the "/var/log" to be the largest due to all the log files.
Thanks again mate and sorry for the late reply. I found that /home/httpd/html/updatecache/ has a lot of .exe, .zip, .cab. Some are dated 2003, 2004, 2005, 2006, 2007. File sizes varies from few hundred KB to more than 100MB. Could this be the cache that my users have downloaded from the internet? Can I just rm all of these or there is a procedure to clear this directory?
