Re: shutting out an IP



                                       
We get these all the time with people trying to buffer over-flow stuff or
script kiddies.
         
We just do a                    
route add <HOST_IP> reject
                 
We find this works a lot better.  No files to modify or junk like that.
We then have a cron job that releases the IP Address in a week or so.

Anything is possible except for skiing through a revolving door.
 It's kinda fun to do the impossible.
