[execnet-dev] Executing Interactively on remote machines

[arun kali raja]

Hi Holger,

Sorry, overlooked the "Working asynchronously/event-based with channels"
section in the document at first glance...

I think that perfectly solves my problem..

*In [1]: import  execnet*

*In [2]: gw =
execnet.makegateway('ssh=wtllab-spirentdev-1.phaedrus.sandvine.com
<http://wtllab-spirentdev-1.phaedrus.sandvine.com>')*

*In [3]: ch = gw.remote_exec("""*

*for item in channel:*
*    channel.send(eval(item))*
*""")*
*In [4]: ch.send('os.chdir("/home/dir1")')*

*In [5]: ch.receive()*

*In [6]: ch.send('os.getcwd()')*

*In [7]: ch.send('os.chdir("/home/dir2")')*

*In [8]: ch.receive()*

*In [9]: ch.send('os.getcwd()')*

*In [10]: ch.close()*

Thanks a lot :)

Regards
Arun Kaliraja.B
