Cisco: Configuration save

[Chuck Dock]

This is the expect script that I run on my slackware box. I schedule this to run once a week via cron. Expect is part of a default slackware 9.1 full install. I also had to create a /tftpboot directory and have the tftp service running. I save the configs for over 515 routers weekly with this, made me a mini hero at my job due to the time it saves.


#!/usr/bin/expect
#
#    rtrcfg.exp -- a script to perform mass configuration changes to
#                  a list of routers using telnet and Expect

#
# Set Behavior
set tftp "10.210.5.36" <<-----REPLACE with your tftp server
#
set vtypasswd xxxxxxx<<<<------REPLACE with the vty password
set enablepwd XXXXXX<<<<------REPLACE with your enable password
set aaa XXXXXXXXX<<<<<--------REPLACE with your aaa password
set userid XXX<<<<<<<----------REPLACE with your aaa username
set RTR [open "/home/chuck/programs/common_files/RTR_LIST" r] <<<<----REPLACE with a path to your router hostname list
set LOG [open "/home/chuck/programs/RESULTS/running_config_results" w] <<<---REPLACE with path to result log file

   if {[ string range $router 0 0 ] != "#"} {
