Press any key to continue, 'e' to exit, 'n' for nopause

Hi There,

Manage to previous issue, however, telnet timeout taking too much time. what could be the issue?

#!/usr/bin/python
import paramiko
import sys
import os
import xlrd
import unidecode
import telnetlib
import time

def telNetConnection(column1,column2,column3):
 host = [ (column1),]
 for host in host:
  print 'Processing'+' '+column1
  user  = (column2)
  password = (column3)
  telnet  = telnetlib.Telnet(host,23,2)
  telnet.read_until('User name:',3)
  telnet.write(user.encode('ascii') + '\r')
  telnet.read_until('Password:',3)
  telnet.write(password.encode('ascii') + '\r')
  #telnet.read_until('>',3)
  telnet.write('statistics mac 1~48' + '\r\r\r')
  #telnet.read_until("    Press any key to continue, 'e' to exit, 'n' for nopause")
  #telnet.write('n')
  telnet.read_until('>',3)
  telnet.write('exit' + '\r')
  output=telnet.read_all()
  f = open('macportdetail.txt', 'w')
  f.write(host+" "+str(output))


os.chdir("/home/anna/scripts")
workbook = xlrd.open_workbook('zyxeldslams.xlsx')
worksheet = workbook.sheet_by_name('Sheet1')

#try:
for x in range(1,375):
    column1 = (worksheet.cell(x,0).value).decode('ascii')
    column2 = (worksheet.cell(x,1).value).decode('ascii')
    column3 = str(worksheet.cell(x,2).value).decode('utf-8')
    try:
        telNetConnection(column1,column2,column3)
    except:
         print "Connection time out"
         pass

This script is taking IP and credentials are excel file and telnet and print output. This file is having morethan 1000+ devices

required support for below issues

1) telnetlib.Telnet timeout is taking two much time, i have provide timeout as 2 second.
2) i am able to print output to single file

current output is

Port: 3

i want to print this as below
1) Sr.No---- incremental serial number
2) hostip --- to whom script is telnetting
3) port, index, vid and mac from output

Sr.No hostip port index vid mac
