As far as I know subprocess, you create a completely new shell environment
underneath for every process.
So essentially, you are now opening a shell, typing your ssh command, closing
the shell (and thus the ssh session), and then create a new shell to type 'ls'.
You can put the commands in a single shell script and run that through
subprocess.
With ssh, it could be somewhat easier:
>>> command1 = "plink -ssh -pw myPassword myUserName@myServerIP ls"
>>> p1 = subprocess.Popen(command1)
So, you can just put the command you want to run at the end of the ssh command.
But, I don't know if plink allows that: I simply don't know plink. If it
doesn't work this way, there may be an option for it though.
(Can't say I like the idea it lets you specify the password on the command
line, but hey.)
