I have this config on Ubuntu 20.04.3 LTS server:
# nmcli con show
NAME UUID TYPE DEVICE
ethernet-enp0s31f6 ecccc29f-bd3f-4bbf-82ce-b1d1978576a1 ethernet enp0s31f6
l2tp-testnet 3be6e607-60f4-4ae3-a703-07ab7c360d10 vpn --
- My problem is the following. When the system boots up and the ethernet connection is established, then it automatically connects the L2TP connection.
- If ethernet is disconnected, and reconnected after a while, then L2TP is also reconnected.
- However, if the L2TP connection is disconnected from the server side, then it is never reconnected.
The documentation is here: https://developer-old.gnome.org/NetworkManager/stable/settings-connection.html and as far as I can tell, my configuration is correct:
- the
autoconnect-slaves option is not effective, because VPN connections are not "slaves" but "secondaries"
- the
autoconnect option cannot be used for VPN connections (the documentation clearly states this)
- the
secondaries option is already set (see full config below)
- the
autoconnect-retries is already set to zero (and it means forever) for both ethernet and L2TP
What should I change if I want it to auto-reconnect forever unconditionally? For example, after the server side has closed the connection, and maybe its address has changed etc.
The trivial answer is to write a bash script that does that, and put it into a cron job. But there must be a better way! NetworkManager already has options to auto-reconnect. I believe I'm just missing the right options.
Details below.
