Hi,

The following script sometimes doesn't work in Python scripting; It does

not go past the login  command  but seems to work interactively  with a
manual telnet session.
Any suggestions ?


 !/usr/bin/env python

import sys
import telnetlib


tn = telnetlib.Telnet("xxx", 4333)              # works ok

tn.set_debuglevel(30)
s=tn.read_eager()                                       #not ok
print s                                                           # not
ok
s=tn.read_eager()                                       # not ok
print s
tn.write("login xx cccc" + "\r\n")               # ok

s=tn.read_eager()                                        # not ok
print s                                                             #not
ok
tn.write("send xx  hello" + "\r\n")               #not ok
s=tn.read_eager()                                        #not ok
print s
tn.write("bye" + "\r\n")

tn.read_eager()
tn.read_eager()

Hi,

not go past the telnet constructor(localhost) command but seems to work
interactively  with a manual telnet session.

#!/usr/bin/env python

import os

import telnetlib
import string


tn = telnetlib.Telnet("localhost")
tn.set_debuglevel(30)
s   = tn.read_until('login:')
tn.write("help" + "\r\n")
s=tn.read_all()
print "got %s" % s

tn.close()
exit
