Date: Tue Nov 1 09:07:27 2005 From: blancher at cartel-securite.fr (Cedric Blancher) Subject: ICMP injection Le mardi 01 novembre 2005 ? 00:11 -0600, Josh Perrymon a ?crit : > Anyone familiar with injecting ICMP or DNS packets with NC? You won't be able to inject ICMP with netcat (nc). Injecting DNS is possible, but you have to craft your UDP payload yourslef. You should try Scapy : http://www.secdev.org/projects/scapy/ Sort of Python shell to craft, inject packets and grab answers, with lots of useful classes. You'll find examples, and in particular all ICMP and DNS stuff you may need. As an example, you can find a DNS request based traceroute onliner with Scapy on page 3 of this article : http://sid.rstack.org/articles/0309_MISC_Traceroute_en.pdf -- http://sid.rstack.org/ PGP KeyID: 157E98EE FingerPrint: FA62226DA9E72FA8AECAA240008B480E157E98EE >> Hi!
