I want to keep look output terse -- it's meant for checking on normal cases, not for troubleshooting difficult ones, and fitting normal situations into minimum vertical space was its major design objective. As mentioned in earlier mail, barf is really what's wanted for troubleshooting.

What might be worth doing is having look check for the expected contents of /proc/net/ipsec_tncfg, and say something *only* if it doesn't look right.

The new doc/vpn.how does mention the desirability of running tcpdump from a separate machine, but it doesn't say it strongly enough. Will fix.

I'd welcome suggestions on better ways of describing the network. The one thing I won't do is adopt a description that's relative to a particular host, so that the file has to be custom-edited for each machine. Avoiding that was a major design objective.

It may be that this is best solved by documentation.
