No and yes, respectively. On ports, it's
pretty much first come, first served.
Why does the problem application "on
occassion" use the port which you wish you
could reserve for some other application?
If you change the sequence of the two
programs' start-ups, you should be able to
move the failure to the other program.

Re: /etc/services reserved ports issue
Thanks for your reply. Unfortunately, the first application MUST be up an running before the second application. The second application needs to use port 2224, however the first application sometimes selects port 2224 for some of its network processes. I have no idea what it uses port 2224 for, but once selected then the second dependent application will not start.
Regards,
Brendan

Re: /etc/services reserved ports issue
the critical port. Then, at start-up, (1)
run the critical-port-grabber, (2) start the
must-be-first application, (3) whack the
critical-port-grabber, and (4) start the
must-use-critical-port program.
This assumes that the must-be-first
application can select a different port if it
finds its first choice occupied (and that
it won't just be waiting for its chance to
pounce).
This also assumes that it wouldn't be easier
to repair the must-be-first application,
Many problems have some goofy solution (like
this) which will work, but is too embarassing
to document thoroughly.

Re: /etc/services reserved ports issue
Thanks for your help. I'm not in a postition to play around with the apps, their both 3rd party products. The solution you've just suggested is what I had been considering ... it just seems a painful way to solve what looks like a simple problem. I suppose the more direct solution is to ask the 3rd party to get heir act together;-)
Thanks again, you've been very helpful.

Re: /etc/services reserved ports issue
If the later, you could assign the port in /etc/clua_services and use the static qualifier to reserve the port.
