Changing directory in a Windows SSH connection using Python

Question

Here is my code to connect to a Windows LAN desktop through SSH (Cygwin server is running on the LAN desktop) from my Windows PC:

import paramiko
ssh = paramiko.SSHClient()
ssh.set_missing_host_key_policy(paramiko.AutoAddPolicy())
ssh.connect('135.24.237.178',username = 'cyg_server',password = 'sandforce')

I am able to connect successfully. But, now if I do this:

command = "cd c:\;dir"
stdin,stdout,stderr = ssh.exec_command(command)
stdout.readlines()

Then pyscripter does not output anything. Can anyone please let me know why and how I can make this code work ?

I am unable to replicate your issue. I am using this code:

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname, username = user, password = pw)
command = "cd c:\;dir"
stdin, out, err = client.exec_command(command)
print "stdout: " + out.read()

The output:

stdout: 

    Directory: C:\

I know this isn't an answer, but it wouldn't fit in the comments. The links provided in the comments don't seem to be particularly helpful either. Here is my normal code for this type of thing:

client = paramiko.SSHClient()
client.set_missing_host_key_policy(paramiko.AutoAddPolicy())
client.connect(hostname, username = user, password = pw)
channel = client.get_transport().open_session()
command = "cd c:\;dir"
channel.exec_command(command)
out = channel.makefile().read()
err = channel.makefile_stderr().read()
returncode = channel.recv_exit_status()
channel.close()                       # channel is closed, but not the client

Hope this helps.
