i added the ~amd64 keyword to my machine and emerge tcpick... however whenever there is traffic on a port it seg faults and exists out. Reproducible: Always Steps to Reproduce: 1.add keyword ~amd64 to packages.keywords 2.emerge tcpick 3.tcpick Actual Results: idl-metro ~ # tcpick -i eth0 Starting tcpick 0.2.1 at 2005-05-10 13:40 EDT Timeout for connections is 600 tcpick: listening on eth0 Segmentation fault Expected Results: Proper logging of eth0 traffic.

phi / # tcpick -i eth0 Starting tcpick 0.2.1 at 2005-05-15 23:44 CEST Timeout for connections is 600 tcpick: listening on eth0 485 packets captured 0 tcp sessions detected Not reproducible on my system. ATs, please test on a stable system.
Well not much i can add besides the strace... that i did ... only difference i can think of is the fact my pc is handling close to 1000pps
Ok, then let's go an debug it properly :-) Please run this: FEATURES="nostrip" CFLAGS="-O0 -ggdb -g3" CXXFLAGS="-O0 -ggdb -g3" emerge net-analyzer/tcpick After that: ulimit -c unlimited # allows core dumps to be dropped gdb tcpick # starts gdb and type in: run -i eth0 # runs tcpick inside gdb In case of a segfault, tcpcik will dump a "core" file. Please attach this to the Bug. Further, when running tcpick in gdb, a segfault will throw you back into gdb console. When this happens, just type in bt and add the output here. Please reopen this BUG when you attach additional info.
