Server was hacked and needs to clean up
The Mandriva 2006 server in my lab was hacked twice in three months.
The server was then used to hack other servers.
I re-installed the OS after first attack. Here the attack came again!
If I simply re-install the OS this time there might be a third attack
and installation is time-consuming. Under Windows you can check REG
or use anti-virus software. In my situation what can i do to detect
virus (trojan) and unusual process?
Your suggestion is highly appreciated.
