Network Statistics

Ipband

It's in the ports tree, it is ment to email you whenever any of your ips
goes over a set limit (300kb/sec)
You can change a bit of code to make it install firewall rules rather
than email you

Hey all

I am currently using tcpstat to check if I am getting attacked, tcpdump
to trace the ips and what type of attack and ipfw firewall to block
them. Sometimes trafshow too but on big attacks trafshow isnt helpful.

1. Do you have any other utils than tcpdump to suggest ?

2. I was thinking to make a script to auto-block (via ipfw firewall) any
ip that spends 300 kb/sec for more than 1 minute. Do you know any tools
that may show me which of my ips are getting more than 300 kb/sec? I
hope you got my point


Best Regards
