[execnet-dev] how to remotely open a program on win box?

[Mathieu Drapeau]

Hi Charles,

In the source of your server script, I did change the makegateway definition
to this:

gw = execnet.makegateway("popen//pytho=C:\Python26\python.exe")

When I connect to the server, a python box pop and when I try to send basic
command to the server, I never receive any answers. The client just wait for
something.
Here is what I tried:
    ch = gw.remote_exec("import os; channel.send(os.getcwd())")
    ch.receive()

Do you know what could cause this problem?

Thanks,
Mathieu
