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. >Release-Note: >Audit-Trail: >Unformatted: To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-bugs" in the body of the message
