Client connection stays open

Hi,

not sure if this is really an issue with paramiko. but I post it anyways to get some help troubleshooting this.
Basically I have the following code:

def ssh(self, ip, username, password):
    client = paramiko.SSHClient()
    client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
    client.load_system_host_keys()
    client.connect(ip, username=username, password=password)
    scp = SCPClient(client.get_transport())
    scp.put('/root/sninstall', '/root/sninstall')
    scp.close()

    cmd_run = '/root/sninstall ' + self.config['snversion'] + ' ' + self.config['os'].lower() + ' ' + self.config['version'][0]
    stdin, stdout, stderr = client.exec_command(cmd_run)
    for line in stdout:
        print '... ' + line.strip('\n')
    client.close()

And run it like this

self.ssh(ip, 'root', '****')

Now, the script runs ok on a RHEL6, I see the output of it, and once done client.close() is called, and returns to the script.
However, if I do the same with a RHEL5 system, the script runs, outputs, and finish.
But the client.close() is not being called.

Like as it is waiting for some more of stdout or stderr.
When I check the system, the script is no longer running, and I could not see any open connections.

But still, it is staying there waiting.
Any help much appreciated.

Not sure this is the proper way, but did you try closing stdin?

How do I close stdin ?
Since I couldn't get it to work I'm using a different approach to do the job.
So not sure if and when I would be able to test this again.
