Hello,
I've been using an expect script to disconnect my router for a very long time. I did a search, some expect scripts to reboot the router have been posted previously, as does the blog post referenced in this thread. The reason I'm posting my own script here is that I use a different method to reset the connection. Since all we really want is to reset the Router-ISP PPP link, my script does only that. Other scripts I've seen all telnet to the router and then reboot it, which of course works, but is unnecessary, and the whole process takes some time. The script I'm using just kills the running ppp daemon, and the connection disconnects and is back up, all within 3 seconds, so it is much more efficient.
Just edit the script below according to your needs (you must change the field), save it to a file (I call mine dsl_reconnect) and give it execute permissions. I run it as a cron job every morning to disconnect before the free night period is up.

I got the code.......
you can use "Crontab" for scheduling tasks
for installing Telnet
Save the file as "Telnet.sh"
Then in the terminal navigate to the location of your Script
then type
OR
just give the file permissions to execute.....
then open the file and choose to execute the script in terminal.
P.S Enter
for giving root permissions for your file. This helps while using Crontab.
Now your router will reboot...
you can use "Crontab" for scheduling tasks
Code:
sudo apt-get install telnet
Code:
#!/bin/shhost=192.168.1.1port=23login=passwd=cmd=reboot(echo open ${host} ${port}sleep 1echo ${login}sleep 1echo ${passwd}sleep 1echo ${cmd}sleep 1echo exit) | telnetThen in the terminal navigate to the location of your Script
then type
Code:
./Telnet.shjust give the file permissions to execute.....
then open the file and choose to execute the script in terminal.
P.S Enter
Code:
chmod +x /Location of your script/Telnet.shNow your router will reboot...
