Question

I am trying to use python’s telnetlib module to get information from a remote device. Unfortunately, it looks like the remote device does not have a “logout” type of command. So you have to manually close the connection with CTRL-] (when manually telnetting). I tried using Telnet.close() but doesn’t seem to return any data.

Suggestions?

HOST = "172.16.7.37"
user = "Netcrypt"
password = "Netcrypt"

tn = telnetlib.Telnet(HOST)

tn.read_until("User: ")
tn.write(user + "\n")
if password:
   tn.read_until("Password: ")
   tn.write(password + "\n")

tn.write("session \n")

print tn.read_until("NC_HOST> ")

tn.close()

Answer 1

Have you tried writing the ASCII character for CTRL+] to the telnet connection?

tn.write('\x1d')
