If ssh is being used interactively (such as being prompted from password), look into pexpect module. http://www.noah.org/wiki/Pexpect Else try the subprocess module (or even commands module); these are lot simpler to program than the more primitive os.execv/os.read/write. If you have already setup keys, ssh should work passwordless whether it's interactive or not (AFAIK). Karthik -- http://mail.python.org/mailman/listinfo/python-list
