>Submitter-Id: current-users >Originator: Louis Mamakos >Organization: UUNET >Confidential: no >Synopsis: tcpdump vs. IPv6 bug >Severity: serious >Priority: medium >Category: bin >Release: FreeBSD 4.0-CURRENT i386 >Class: sw-bug >Environment: FreeBSD-current as-of 29 Feb 2000, IPv6 configured >Description: If a host has both A and AAAA records in the DNS, then tcpdump will complain that you're trying to apply the 'ip' modifier to an ip6 host. Curiously, the reverse also breaks: >How-To-Repeat: # tcpdump ip host whizzo.transsys.com tcpdump: 'ip' modifier applied to ip6 host # tcpdump ip6 host whizzo.transsys.com tcpdump: 'ip6' modifier applied to ip host >Fix: or at least a work-around tcpdump ip and host whizzo.transsys.com but this is ugly and not backwards compatible.
