Thanks to everyone who replied. The overwhelming majority said "get lsof", and
lsof -i tells me just what I need to know, with just one niggle - it seems
not to distinguish between source and destination address/port combinations,
so that it seems impossible to express "show me all the connections from host
x to port y". However, this is a very minor gripe, and it probably means I
haven't delved the details out of the man page. It would also be nice to have
extended host selection (i.e. everyone not on the local network), but I'm sure
that these can be built into lsof, or postprocessed.
FWIW, I did check the archive, but I couldn't find any query which looked like
what I needed. Hopefully, this email will be found by future enquirers before
it gets asked again.
The non lsof answers mentioned various weird and wonderful options to netstat.
Maybe there are some on other systems, but I certainly couldn't make them work
on alpha-osf. To all the people who suggested ways of munging netstat I say
thanks for the contribution, but have you heard about lsof? :-)
