`ipsend' is a package which can send arbitrary IP packets, been able to specify on command-line all the IP, ICMP, TCP or UDP options. It's very useful to diagnose network problems, to exploit DoS bugs related to strange packets, etc. It's GPLed, and it's written by me ;) -- Juan Cespedes Debian Developer <cespedes@debian.org> ACM Member <cespedes@acm.org> Key 42AB53B5 fingerprint = EE B9 E0 7B 57 59 6E 49 12 CF 8D 17 1C 17 EC B3
