I thought that maybe "netstat -an" relies on some standard API
to list the kernel's established TCP sessions on various OSes.
Forking an executable for each connection would of course be an
overkill. At most - make a netstat daemon (or thread) and query
it with a pipe ;)


Given your reply above, I think for many intents and purposes
the single value defined by admin in a config file would do.
It just has to become not only defined for POSIX, and used in
place of missing {if_addr} in those two spots. And also it
should become documented, at all and for such use in particular :)

I cannot promise I'd look into this anytime soon, there are some
quests at $work to do with higher priority... Then again, I thought
so about several of the features I've committed this weekend ;)
