Just an FYI, I've released iptstate 2.2.0.

Version 2.2.0 marks the porting of iptstate to libnetfilter_conntrack (the
new API, specifically). This allowed lots of new features in this version
such as deleting states from the conntrack table, displaying the per-state
bytes/packets counters, and more.

Other features include better scrolling support, display of ICMP IDs, and
support for having a state table larger than 32767 entries.

Thanks to Pablo and everyone else here for answering my
libnetfilter_conntrack questions!

"Never write it in C if you can do it in 'awk';
 Never do it in 'awk' if 'sed' can handle it;
 Never use 'sed' when 'tr' can do the job;
 Never invoke 'tr' when 'cat' is sufficient;
 Avoid using 'cat' whenever possible" -- Taylor's Laws of Programming
