The Sify LAN is connected 24x7, and so are the attempts by some of my neighbouring(?) users to launch NetBIOS attacks. The attempts come from only a select handfull of IP addresses, they might be some wannabe crackers/freeloaders, or some virus using them as a host, but they are really annoying me. I know I can turn off the warnings in ZoneAlarm anytime, but when I have their IP addresses(they are all local: a.b.c.x , a.b.c=same as in my LAN config.), isnt' there something, i can do? Whom can I complain to? the Cableguy or Sify CustCare. Right now i just ping them back to say hello, but one of them, the most troublesome h34r: , i wanna give a boot :wacko: . Please comment.
