Hi all.
I currently try to start conntrackd to test it.
CentOS release 6.3 (Final)
Linux lb1.local 2.6.32-279.11.1.el6.x86_64 #1 SMP Tue Oct 16 15:57:10 UTC
2012 x86_64 x86_64 x86_64 GNU/Linux
This is a VirtualBox vm.
I try:
/usr/sbin/conntrackd -C /etc/conntrackd/conntrackd.conf -d
My config:
[root@lb1 log]# egrep -v '^\s*#|^$' /etc/conntrackd/conntrackd.conf | less
