Execute a script after a VPN connection is started

rated 0 times [ 16] [ 0] / answers: 1 / hits: 9398 / 3 Years ago, thu, july 15, 2021, 6:31:57

I'm starting a VPN connection using Network Manager.
Once the connection is established I have to change MTU in order it to work properly.
For example:

sudo ifconfig ppp0 mtu 777

It is very annoying to execute this command every time I open a VPN connection. Is there any idea to create a script that would execute this command automatically once the connection is established (ppp0 interface is up)?

Create a script in /etc/network/if-up.d, containing

#!/bin/sh



if [ "$IFACE" = "ppp0" ]; then

    ifconfig ppp0 mtu 777

fi

and make it executable.
