# now connect try: sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM) sock.connect_ex((hostname, port)) except Exception, e: print 'Connect failed: ' + str(e) traceback.print_exc() sys.exit(1) t = paramiko.Transport(sock) event = threading.Event() t.start_client(event) print "started client" event.wait(15) if not t.is_active(): print 'SSH negotiation failed.' sys.exit(1) else: print "SSH negotiation sucessful" print "doing authentication" t.auth_password(username, password, event) event.clear() event.wait(20) ----------------- the result is : started client ssh negotiation sucessful donig authentication .... paramiko.SSHException : No existing session ------------------- I am sure that the username and password exists properly. what is the problem?? -- View this message in context: http://www.nabble.com/paramiko.SSHException-%3A-No-existing-session-----tp19823051p19823051.html Sent from the Python - python-list mailing list archive at Nabble.com. -- http://mail.python.org/mailman/listinfo/python-list
