  We're trying to put together a set of official packages for vendors
who refuse to upgrade.  But work gets in the way.

  They're not using an assigned port.  That's rude.

  You can use a "listen" section.  "type = proxy" and "port = 0".

  Use a "listen" section.  This is documented.

  At least, it's documented in versions of the server which aren't 4
years old.

  The Debian maintainer seems to have disappeared.  And he's not
responding to email.  We'll see if we can get someone else to replace
him.  Similarly, RedHat is using 2.1.12, and shows no interest in
upgrading.  God only knows why.  Maybe they hate their customers?
