It’s a problem I’ve found in Maya 2009 running on Vista 32.

if you open a port in Maya, you can’t access it because you get a “connection refused” error.

You can test it running this script in the python script editor

You should see a sphere in the origin, otherwise in the case you use maya 2009 on vista 32 you will see the connection refused error.
I think is a problem that has to do with IPv6. I disabled it in my vista but it keeps displaying the same error.

Any idea?

I’m on Vista 64 and I’m not having any luck getting commandPort to work either.
Any input on whether this works would be great.

After some trial and error I was able to get commandPort to consistently work.  I had it work sometimes, and then not other times.

I found that what I had to do is run the commandPort command twice. Like so:

Running only one of those commands would allow me to connect with Maya through telnet with Putty, but with Python I would get a ‘Connection refused’ error.  It was frustrating because as I was experimenting it would occasionally work when I ran the command in that order and it took me a while to figure out why.

I’m running 2009x64 on Vistax64, I don’t know if this is a problem in other versions or OSs.
