conntrack: add -o ktimestamp option (it requires linux >= 2.6.38)
This option requires Linux kernel >= 2.6.38, you have to enable conntrack timestamping with: echo 1 > /proc/sys/net/netfilter/nf_conntrack_timestamp # conntrack -L -o ktimestamp udp 17 59 src=192.168.1.128 dst=192.168.1.1 sport=52050 dport=53 src=192.168.1.1 dst=192.168.1.128 sport=53 dport=52050 [ASSURED] mark=0 delta-time=121 [start=Thu Feb 17 17:41:18 2011] use=1 # conntrack -L conntrack v0.9.15 (conntrack-tools): 20 flow entries have been shown. udp 17 31 src=192.168.1.128 dst=192.168.1.1 sport=52050 dport=53 src=192.168.1.1 dst=192.168.1.128 sport=53 dport=52050 [ASSURED] mark=0 delta-time=149 use=1 # conntrack -E -o ktimestamp ...
