Dear Ladies and Gentlemen, I am writing to say that I think there is something wrong with libpcap/bpf/tcpdump shipped with 4.0-RELEASE and 4.1-RELEASE. The problem is that as soon as filter expression is given to tcpdump eg tcpdump -x -s1500 -l port telnet, then the only packets displayed are those from the localhost (that running tcpdump); the replies are *not* shown. If the filter is removed, both client and server packets are displayed. Thank you.
