I've just noticed that my server is being hammered by the www.puritysearch.net
I've been reading about fail2ban but am unable to find a guide on how to set it up on a Ubuntu 8.04/ISPConfig 2 server. This is a production server so I'm wary of messing things up.
What do I need to do to block www.puritysearch.net?
Will following these this guide answer my needs: http://www.howtoforge.com/fail2ban_debian_etch
Am I even on the right track here?
Any pointers will be appreciated.
