My setup is slightly different to yours maybe - but here goes
Internet -> Billion 8800NL -> Linksys WRT3200 ACM
The Linksys is running Lede
Billion is in Bridge mode - Linksys does the connection (I have this so my Linksys can stay as my main router even if I change my modem)
On the HA Server I have 3 scrips - A master script and one for each device
And a crontab that runs hourly
0 * * * * /home/user/scripts/restart_inet_connection.sh >> /home/user/scripts/inet.log 2>&1
Main Script
#!/bin/bash
fping -u google.co.uk >& /dev/null
if [ $? -ne 0 ]; then
echo "Date: $(date)"
echo "$(date): Google.co.uk is not responding!! Attempting to repair internet connection."
echo "$(date): Restarting Billion 8800NL"
/home/user/scripts/restart_billion.sh 192.168.0.254 username password
sleep 10s
while ! fping -q 192.168.0.254 ; do echo "Billion has not rebooted yet"; sleep 10s ; done
echo "$(date): Billion is online. Waiting 1 minute for ADSL to sync"
sleep 1m
echo "$(date): Restarting Linksys 3200"
/home/user/scripts/router_reboot.sh 192.168.0.1
sleep 10s
while ! fping -q 192.168.0.1 ; do echo "Router has not rebooted yet"; sleep 10s ; done
# while ! fping -q google.co.uk ; do echo "Internet is not responding yet"; sleep 10s ; done
echo "$(date): Google.co.uk is now responding - Internet is now active again."
else
echo "$(date): Google.co.uk is responding - Internet is active."
fi
On the Billion its running Telnet
Billion Script
#!/usr/bin/expect
#If it all goes pear shaped the script will timeout after 20 seconds.
set timeout 20
#First argument is assigned to the variable name
set name [lindex $argv 0]
#Second argument is assigned to the variable user
set user [lindex $argv 1]
#Third argument is assigned to the variable password
set password [lindex $argv 2]
#This spawns the telnet program and connects it to the variable name
spawn telnet $name
#The script expects login
expect "Login:"
#The script sends the user variable
send "$user\r"
#The script expects Password
expect "Password:"
#The script sends the password variable
send "$password\r"
#This hands control of the keyboard over two you (Nice expect feature!)
#interact
#Reboot
expect "> "
# Change the following value to whatever your devices reboot command is.
send "reboot\r"
interact
On the Linksys running LEDE I have a SSH pre-shared key with the HA server - LEDE is just Unix
Linksys 3200
#!/bin/bash
if [ "$#" -ne 1 ]; then
echo "Illegal number of parameters";
echo "Usage: $0 ROUTER_IP";
exit;
fi
RouterToCheck=$1;
command="ssh root@${RouterToCheck} \"ifdown wan; sleep 5; ifup wan\""
result=`eval ${command}`
It’s all a bit convoluted but it checks is the WAN is up and reboots the right devices in the right order. Feel free to change for your devices (I had it working on a different device before I got the Billion and the Linksys)
