This is my first post and I am very new in python and paramiko. My requirement is to:

ssh server1.com
ssh from server1 to server2.com
ssh from server2 to server3.com
run multiple UNIX commands on server3.com like declog, decrypt, scp, grep etc.... and finally create .tgz file
Move .tgz file from server3 to server2 to server1 to local

I did Google and found that python script with paramiko module can do this job. I was able to ssh to server1 but don't know how to ssh server2 and server3.

Code:

    ssh = paramiko.SSHClient()
    ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    ssh.load_host_keys("/cygwin/home/skhome/.ssh/known_hosts")
    privkey = paramiko.RSAKey.from_private_key_file ("/cygwin/home/skhome/.ssh/id_rsa")
    ssh.connect('server1.com', username='sk000g',pkey=privkey )
    # Not sure how to connect sever2, server3 and execute UNIX commands

Thanks, Shah

I recommend to use `pexpect` rather than paramiko for a job like this – wim Apr 22 '13 at 03:36
