[plug] Attempted Intrusions

[Marc Wiriadisastra]

Hi All,

I don't know if there is something I can do about this.  Everyday I 
receive a log of ssh attempts and the ip address which is pretty 
straightforward.  However on a daily basis I have ip's that obviously 
are trying to enter my computer that are not supposed to and on a daily 
basis I have sent emails to firms around the world to advise them of 
people trying to access my computer.

The problem is there is this one ip and I say one who is from China that 
constantly tries to access my network I have sent numerous emails to 
that firm to the abuse email address.  Now for some reason I have had no 
response whether thats because they don't care I don't know.  However is 
there some other way I can put a stop to it.  He or she is obviously 
running a program which spits out generic usernames such as root, adm 
and the like however obviously ssh blocks all of those usernames and 
really I'm not so worried about the access because more than likely he 
won't get in.  However its becoming annoying because he's getting the 
log filled up to a ridiculous quantity.

Has anyone got any suggestions I'm tempted to just list his ip and just 
do a drop using iptables however I really don't wanna go down that path. 
  Is there a register of some sort to cause him issues???

Regards


Marc
