Force RPC to use a specific port range

[pras...@gmail.com]

There is a requirement for 1 of our Clients that they want the
Application,could be login or communication to happen,only via a
specific port range (4000-4100) using RPC services.
The same was done for windows & this is what the Windows Guy put in

"Customer is not able to login to the apps on the server from the
client network.

This issue for another windows apps server was resolved by forcing the
OS to use specific RPC ports ( 4000 - 4100) and we opened the above
ports on the firewall. Please see if you can do the same on AIX too."

Based on this The nw guy opened the specified ports on the firewall &
asked me to check.
I did a telnet localhost 4000 & also a telnet localhost 4080 & it said
connection refused.

I also tried restarting rpc services via stopsrc -g nfs & startsrc -g
nfs & refresh -s inetd...but to no avail

How do we force the OS use specific RPC ports ( 4000 - 4100)

I may be misunderstanding, so please forgive me if I am :)

I'm assume your app is registering with portmapper so clients can find
it? Tho I'm not 100% sure as you are attempting to go to specific
ports....

It it normally a function of the application to decide what port to
use. For instance a RPC server that IS using portmapper will start
up, pick a "random" port and then tell portmapper which port it's
using.

Are you able to configure the app to use specific ports?

Thanks
