Very probably you didn't want to start two pipes  (two processes on your 
host)



Can you ssh or rsh to zone 1?

Then you want probably something like:

os.popen('echo zonename | ssh <zone1>')


If not you could look at pexpect, though I didn't use it myself so far.
just look at the thread 'SSH utility' to get some examples.
you just had to replace 'ssh' with 'zlogin'

( http://www.noah.org/wiki/Pexpect )



Or you could try popen2, http://docs.python.org/lib/module-popen2.html

Strange thing is though, that popen doesn't seem to exist on my python.
Perhaps it's not a standard library.
No idea. I myself am rather new to python :-(


However if you want to try popen2 read also 17.4.2 'Flow Control Issues'
in order to be sure, that your program doesn't deadlock



[ z1_stdin , z1_stdout ] = os.popen2('ssh <zone1')
z1_stdin.write('zonename\n')
z1_stdout.readline()
