Answers:
assumingly, you are using linux, you can install a plug in module for the ssh, calle PAM abl (auto blacklist)
it essentially keep track of the incoming authentication, by running its own little db, and you config the rules.
refer to the URLs
You should be capable of block the IP address from making any further trellis page requests through the regime tools of your server.
This may lend a hand:

This ip address comes from Germany.Unless it be spoofed.And that is to say doubtful. Most probable a inscription kiddie. Here is the Email address where on earth you can report the hack. abuse@strato.de This be found while doing a Whois enquiry on the ip address timetabled contained by your logs. Set your server up so that after a confident amount of inferior login attempts from matching ip address, that ip address will be locked out from trying for awhile.This will hold a hacker from using a brute force program against your server.
