thanks, what happens with the ssh connection after def process(cmd) is
done

Do i not need to remove the 'else' for it to work ?
Also can i execute multiple commands at once ?

import os, time

def ssh(user, rhost, pw, cmd):
        pid, fd = os.forkpty()
        if pid == 0:
                os.execv("/bin/ssh", ["/bin/ssh", "-l", user, rhost] +
cmd)
                time.sleep(0.2)
                os.read(fd, 1000)
                time.sleep(0.2)
                os.write(fd, pw + "\n")
                time.sleep(0.2)
                res = ''
                s = os.read(fd, 1)
                while s:
                        res += s
                        s = os.read(fd, 1)
                return res

print ssh('username', 'serverdomain.com', 'Password', ['ls -l'])
