The "Ping the remote host" option calls ping_host.nasl, and using >>Ethereal I found what seems to be the problem.

The relevant part of ping_host.nasl is below (sorry if >>the formatting is goofy): Is this by any chance on a SuSE 9.0 box? There is a bug in the kernel on 9.0 which breaks nmap etc in just this way. The work around is to let the kernel compute the header checksum for you.
