Hello, ive been struggling with this for a couple weeks now and was hoping
someone might be able to help. I have an older Cognex camera that I need to
communicate with via telnet. I can get a response from the camera when I
initiate a telnet session but I dont seem to get any response when I write the
user name to the camera - I havnt been able to get any response writing
anything. Im using python 2.7 and windows xp. here is the code:
[code]
>>>import sys
>>>import telnetlib
>>>HOST = "10.31.18.21"
>>>USER = "admin"
>>>tn = telnetlib.Telnet(HOST)
>>>tn.read_until("Login: ")
"Welcome to In-Sight(R) 4001 Session 1\r\nUser:"
>>>tn.write(USER + "\r\n")
>>>tn.read_until("User: ")
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "C:\Python27\lib\telnetlib.py", line 319,
return self.read_very_lazy()
File "C:\Python27\lib\telnetlib.py", line 395,
raise EOFError, 'telnet connection closed'
EOFError: telnet connection closed
>>>
[\code]
if i do a read_all instead of read_until for user I just get "..." returned.
Im assuming tn.write command isnt working? any help would be greatly
appreciated.
thank you
Chris
