Linux Telnet Script to Reboot Dlink 502T under linux

[spynic]

well this method of modem rebooting has been around in the windows environment,
of great use to mtnl NU users..
but i could hardly find any script for linux.. finally after lots of searching, i found some scripts, did some editing for Dlink502T and got it running under linux
here's how its done..

Requirements : expect

# yum install expect

create file telnet.exp
open and add this: (you may change the ip address and password if you need)

#!/usr/bin/expect -f

set timeout 5

# router user name
set name "admin"

# router password
set pass "password"

# router IP address
set routerip "192.168.1.1"
# start telnet
spawn telnet $routerip

# send username & password
expect "Login:"
send -- "$name\r"
expect "Password:"
send -- "$pass\r"
# execute command
expect "#"
send -- "reboot\r"
# exit
expect "#"
send -- "^D"

set permissions to run script:

# chmod +x telnet.exp

run script

$ ./telnet.exp
