I am dealing with this in my Port ACL patch. The range used for
random (aren't they called anonymous as well?) port assignments
will be tunable, on a per-user basis if you like, and the range
need not be contiguous, so you could reserve 6000-6020 for X,
another range for IRC, etc.
You can search the archives for the string "PACL" to see my
original announcement, or just send me mail. If anyone plans to do
some work on this, then PLEASE contact me. My scheme might not be
the best one, so if anyone else has a better idea, I'd like to
integrate that into PACL. Plus, the sysctl interface for pacl is
sorta-close to done.
Can you post a copy of this patch when it nears completion? I'd like
to merge it into the current 2.1.x networking quickly after you are
ready with it, so this problem can be history.
Later,
