Tutorial Check VPN Client Status from Android phone

[Jo Sidarta]

Hi,

Thanks to this thread and the developer of SSH Button app

I created a simple script that will allow you to check the router VPN client status from the Android phone.
I installed this on my family phone so that they can check whether the client VPN is running or not (against a specific smart tv) to ensure that they can watch certain regions of movies.

Steps:
1. Login to router through SSH
2. Create a new file and save it into a specific location (in my case: /jffs/scripts/chkVPN) - don't forget to chmod +x to the file

#!/bin/sh
#This script will check VPN client status
#Usage: chkVPN <client number>
#E.g: chkVPN 1
#Returned results:
# - Exit 0 for running
# - Exit 1 for not running

status=$(nvram get vpn_client$1_state)

#If running, return 0 so that SSH-Button shows "OK" result
if [ $status -eq 0 ]
then
  echo "VPN $1 is not running - exit 1"
  exit 1
else
  echo "VPN $1 is running - exit 0"
  exit 0
fi

3. Download SSH Button app from Play Store
4. Create a new entry
For example to check VPN client 1, you would put the following command:

/jffs/scripts/chkVPN 1

5. Create a widget from this SSH Button and you will be able to see the returned result
When VPN is running:

When VPN is not runnig:
