erstellen von lokalen und remote gateways

>>> import execnet
>>> gw = execnet.makegateway()
>>> gw_remote = execnet.makegateway('ssh=codespeak.net')
>>> gw.remote_exec('import sys;channel.send(sys.version)').receive()
'2.6.6 (r266:84292, Apr 20 2011, 09:34:38) \n[GCC 4.5.2]'
>>> gw_remote.remote_exec('import sys;channel.send(sys.version)').receive()
'2.4.2 (#1, Dec 22 2005, 11:47:59) \n[GCC 3.4.4 (Gentoo 3.4.4-r1, ssp-3.4.4-1.0, pie-8.7.8)]'

interaktion mit modulen und funktionen

>>> import remote_example
>>> ch = gw.remote_exec(remote_example) #whole module
>>> ch.send('test')
>>> list(ch)
[(0, 't'), (1, 'e'), (2, 's'), (3, 't')]


>>> ch = gw.remote_exec(remote_example.uhm) # non pure function
