Help my with an easy script to show vpn status! :)

[Deleted member 27741]

I have a super simple script that I want to modify and I know it will be child's play for you guys.

The below script outputs a 0 or a 2 depending on if the vpn is connected.

What I would like to do is make it a bit more sophisticated. So, if vpn_client1_state is 2 (connected) it would output something more informational like-

VPN client 1 connnected your ip address is <ip address>

Then if vpn_client1_state is 0 (disconnected), something like-

VPN client 2 disconnected your ip address is <ip address>

I think the reason I made it this simple in the first place is that I had trouble finding the WAN ip address when connected to the vpn client.


#!/bin/sh

logger -t $(basename $0) "STARTING SCRIPT, PARAMETER: $1"
echo "vpn_client1_state"
echo "CTRL+C to stop"
while true
do
nvram get "vpn_client1_state"
/bin/sleep 5s
done

This will give you your IP address for vpn_client1

ip route show table 111 | grep "via $(nvram get wan0_gateway)" | awk -F' ' '{ print $1 }'

Just a question
I.m using:

ip route show table main| grep "via $(nvram get wan0_gateway)" | awk -F' ' '{ print $1 }'

and get output:

x6.227.xx.xxx
default

and need to cut away "default" . I.m not so good to use either cut or sed, how to implement?

Thank you
octopus

For @000111 info, you would use table main instead of table 111 if you are not using policy based routing. Then, try this to strip out the 'default' answer

ip route show table main| grep "via $(nvram get wan0_gateway)" | grep -v "default" | awk -F' ' '{ print $1 }'

Thank you working.
I.m using main and policy routing.
