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 Sync { Mode FTFW { } UDP { IPv4_address 192.168.100.11 IPv4_Destination_Address 192.168.100.12 Port 3780 SndSocketBuffer 1249280 RcvSocketBuffer 1249280 Checksum on } Options { } } General { Nice -20 HashSize 32768 HashLimit 131072 LogFile on LockFile /var/lock/conntrack.lock UNIX { Path /var/run/conntrackd.ctl Backlog 20 } NetlinkBufferSize 2097152 NetlinkBufferSizeMaxGrowth 8388608 Filter From Kernelspace { Protocol Accept { TCP } Address Ignore { IPv4_address 127.0.0.1 # loopback IPv4_address 192.168.100.11 # virtual IP 1 IPv4_address 192.168.100.12 # virtual IP 2 IPv4_address 10.0.2.111 IPv4_address 10.0.2.112 } State Accept { ESTABLISHED CLOSED TIME_WAIT CLOSE_WAIT for TCP } } }

With strace (I haven't found an obvious problem in its output): strace /usr/sbin/conntrackd -C /etc/conntrackd/conntrackd.conf -d
