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

import socket
from maya import cmds
cmds.commandPort(n=":7890")
s = socket.socket()
s.connect(("localhost", 7890))
s.send("sphere")
s.shutdown(2)
s.close()

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:

commandPort -eo -n "127.0.0.1:7890";
commandPort -eo -n ":7890";

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.

Thanks.

I was trying to connect Cutter to MAya with a Vista system and had a similar connection problem. Your solution is brilliant.

Hey guys,

I just wanted to chime in on this thread.  This seems to be IPv6 issue here with Maya.  So the workaround is to set a environment variable in the Maya.env to force Maya into IPv4 under Vista OS.

MAYA_IP_TYPE = ipv4

this should get around your port issue.

cheers!

I have tried all of the above solutions in Maya 2011 64-bit and Mudbox 2011 64-bit and nothing seems to work…

I can export from Maya into Mudbox (usually with FBX errors!) but I cannot “send to Maya” from within Mudbox.

Really very annoying…

Again thanks for the information, at least it taught me more about the Script Editor.
