Script para resetear el router - Instalación del Script bajo linux

Tenemos que tener el paquete expect instalado, una vez lo tengamos creamos un fichero con el siguiente texto:

3com 812:

#!/usr/bin/expect -f
set force_conservative 1 ;
if {$force_conservative} {
set send_slow {1 .010}
proc send {ignore arg} {
sleep .2
exp_send -s -- $arg
}
}
puts "\n"
spawn host sourceforge.net
expect -exact "sourceforge.net has address 66.35.250.203" {puts "todo
ok\n";exit}
spawn telnet IP DEL ROUTER
expect "ogin:*"
send -- "LOGIN DEL ROUTER\r"
expect "assword:*"
send -- "PASSWORD DEL ROUTER\r"
send_user "\ reseteo el router: "
send -- " reboot\r"
expect -exact "Please confirm the request.(No/Yes):"
send -- " yes\r"
expect -gl "\\\[*]\$*"
puts "\n"
exit

expect -exact {

}

send -- " reboot\r"
expect -exact "Are you sure? default: n (y,n)"
send -- "y\r"

NOTAS IMPORTANTES:

• En algunas versiones de linux puede que tengaís que cambiar la linea de:
  expect -exact "ns1.telefonica-data.com has address 194.224.52.36" {puts

"todo ok\n";exit}por:
expect -exact "ns1.telefonica-data.com A 194.224.52.36" {puts
"todo ok\n";exit}

• Si quieres solo renegociar la conexión adsl cambia el reboot por:
  set adsl reset( en el 3com 812 )

Luego dais permisos de ejecución al fichero ( con chmod +x fichero ), luego añadir al cron la tarea de ejecutar el ficherito de una forma similar a esta:

/home/yo/NOMBRE DE FICHERITO > /dev/null

Ojo, darle permisos para que sólo lo vea root ya que las claves del router van a estar en texto plano en el fichero.
