以下のコードのように、telnet セッションを使用する必要があります。
class ModTelnet(MXComm):
def __init__(self):
MXComm.__init__(self)
def _connect(self):
#connect to telnet session @ localhost port 4444
try:
HOST = "localhost"
port = "4444"
# tn = telnetlib.Telnet(HOST, port)
tn.open(HOST, port)
except:
print "Connection refused"
def _receive(self):
#receive data (= msg) from telnet stdout
try:
data = tn.read_all()
return data
except tn.eof.ERR as ex:
if 'timeout error' not in ex.args[0]:
print 'Connection error:', ex
raise Disconnected()
def _send(self, data):
#send command to telnet session
try:
tn.write(data + "\n")
except tn.socket.error as ex:
if 'timeout error' not in ex.args[0]:
print 'Connection error:', ex
raise Disconnected()
発生したエラーは次のとおりです。
QApplication: Invalid Display* argument
Connection refused
Exception in thread Thread-1:

問題は、最初のメソッド「接続」で開いている telnet セッションを認識しないように見えることです...どうすればこれを最善の方法で行うことができますか?
