Having trouble with py.test remote

I love py.test and am trying to get the remote test execution feature to work so I can run tests on a remote machine. There is very little doc and I am getting frustrated with it. Any help figuring out what I am doing wrong is appreciated. Here is my command line on the main server:

c:\Python26\Scripts\py.test --dist=each --tx socket=192.168.1.11:8888 tests\test_guest_install.py

If I read the doc right, this should push the script to the remote machine and run it. Here's the output on the other side:

C:\Users\D开发者_如何学Goave\Desktop>c:\Python26\python.exe socketserver.py

Could you try to rerun with latest versions of pytest and pytest-xdist?
