ZTE H168N Reboot remotely using expect script

My ZTE H168N ADSL/VDSL modem has telnet server on it.

Sometimes, I need to reboot it. But it need to go there, and press its ON/OFF switch… takes time.

In order to reboot it remotely over telnet, there are some steps need to be followed.

To achieve this goal, I wrote a very simple expect script. First, you must install expect. I use Linux Mint, but I saw expect has windows port too 🙂

For linux: sudo apt-get install expect

And write this script:

#!/usr/bin/expect

spawn telnet 192.168.2.1

expect “Username:”

send “admin\r”

expect “Password:”

send “ttnet\r”

expect “>”

send “enable\r”

expect “Password:”

send “zte\r”

expect “#”

send “shell\r”

expect “Login:”

send “root\r”

expect “Password:”

send “root\r”

expect “#”

send “reboot\r”
expect “#”
sleep 5

After you execute, your H168 will reboot in 10 seconds, voila !
