[Luca N. <su...@al...>]

Hi to all users,

I have a Centos 5 and after a correct compilation of tcpick i tried  
to use this command with a segmentation fault.
This is a Linux / Proxy Arp machine with iptables.

root@firewall-lb1 cron]# tcpick -i eth0 "host 99.66.212.22 and port  
80" -wRu
Starting tcpick 0.2.1 at 2009-04-07 18:44 CEST
Timeout for connections is 600
tcpick: listening on eth0
setting filter: "host 99.66.212.22 and port 80"
