Display output in a certain format. With the extended output option, this tool
displays the layer 3 information. With ktimestamp, it displays the in-kernel
timestamp available since 2.6.38 (you can enable it via echo 1 >
/proc/sys/net/netfilter/nf_conntrack_timestamp).
+The connlabels output option tells conntrack to show the names of labels that
