It's similar to netstat -M on an ipchains box, in fact there's a perl script
netstat-m that gives a tabular view, 

Proto Local Address                 Foreign Address               State

Resolves the IP numbers and displays actual ports.

Here's a raw line from /proc/net/ip_conntrack:

tcp      6 105145 ESTABLISHED src=192.168.5.3 dst=64.76.84.140 sport=4655
dport=6346 src=64.76.84.140 dst=65.26.52.58 sport=6346 dport=4655 [ASSURED]
use=1

An interesting note, that connection has not been up for days, node .3 has
been shut down several times, so it appears that there's a missing cleanup
mechanism.
