I have a requirement where i need to do the following
I need to ssh to a linux box , run a command , get the output back and i need to do some manipulations.
Is that possible via python subprocess module.
Basically i need a .py code in which i will give the ip address, username and password for connecting to the linux box and run a command and get the output.
Also is that possible via any other modules available in Python.
Suggestions are welcome.
Your question is tagged with "paramiko", so why don't you just use that?

ssh to a linux box (or any other ssh server):
>>> import paramiko
>>> ssh=paramiko.SSHClient()
>>> ssh.load_system_host_keys()
>>> ssh.connect(hostname='localhost', username='haiprasan86', password='secret')
>>> print ssh
<paramiko.SSHClient object at 0xdf2590>
run a command:
>>> _, out, err = ssh.exec_command('ls -l /etc/passwd')
>>> # block until remote command completes
>>> status = out.channel.recv_exit_status()
>>> print status
0
get the output back:
>>> print out.readlines()
['-rw-r--r--. 1 root root 2351 Mar 27 10:57 /etc/passwd\n']
I don't know what manipulations you want to do.
If it's just one command, you can simply append it to the command line:
ssh user@host "echo foo"
would then return foo. If you use ssh-agent with your public key in the remote host's ~/.ssh/authorized_keys-file then you don't even need to ask for the password.
