query command port across Maya sessions

Anonymous — Tue, 07 Jul 2009 12:59:57 GMT

SO I open two sessions of Maya

In session 1 I open a command port via

commandPort -n ":8000";

If in session 1 I query the command port creation with:

commandPort -q ":8000";
// Result:1//

It sees the port.

But if in the second Maya session I query the commandPort via:

commandPort -q ":8000";
// Result:0//

It thinks the port has not been created. But port 8000 is taken and
cannot be used. How can I query that a command port is taken in this
way, across multiple session of Maya?

Maya only knows about it's own session. I'd check with something like netstat -na.

But it cannot generate a port at :8000 from session 2 even though query says the port is free. Hmmmm..., maybe I've got this backwards. I was trying to find the free port before creating it, seemed like the smart thing to do. Maybe I should just start trying to make sequential commandports and query if the result is true at each attempt then stop the process after the first succesful commandPort creation.

Nope....that didn't work. Executing something that causes an error forces the userSetup.mel script to terminate. Can't execute a commandPort initialization with explicit port number. If it fails so does the rest of the mel script. Back to the drawing board.

What I'm trying to do is force a commandPort creation at Maya startup, but using a defined and available port number. If anyone knows how to accomplish this it would be appreciated.
