Message-ID: <46CE8C05.5060202@nj.cpsecure.com> (raw)

Hi, all
	When I checked /proc/net/ip_conntrack in my Linux server, I found some 
strange tracks like the following:

[normal case]
tcp      6 387113 ESTABLISHED src=219.135.189.40 dst=58.60.9.41
sport=2391 dport=443 src=58.60.9.41 dst=219.135.189.40 sport=443
dport=2391 [ASSURED] use=1

[strange track]
tcp      6 377231 ESTABLISHED src=222.173.17.207 dst=219.135.189.11
sport=19691 dport=3815 [UNREPLIED] src=219.135.189.11 dst=222.173.17.207
sport=3815 dport=19691 use=1

As we kown after SYN->SYN,ACK->ACK. TCP connection is in ESTABLISHED
state. and the ip_conntrack "see" the REPLY direction packet, I think
the conntrak should be ASSURED. not UNREPLIED.

So, pls help me. My kernel version is 2.4.22

Thanks in advance  :-)
