Thanks! I've added the "!is_external" check to my latest development
patch revision at:
https://github.com/slyon/NetworkManager/commits/netplan-nm-1.40
So this bug report is now mostly about comment #10, where the openvpn
client/plugin is creating a temporary tunX device, which is displayed as
"external" in "nmcli d", but still a Netplan YAML file is created in
/etc/netplan on "nmcli con down <VPN>". I can easily reproduce this
issue locally, using Canonical VPN and see tunX connection definitions
piling up in /etc/netplan/ when bringing it up&down a few times in a
row.
This doesn't seem to affect the functionality, though. The VPN is
connection is working when up in each iteration.
** Description changed:
+ *** Note: This bug is mostly about comment #10, now ***
+
When creating an OpenVPN connection, a temporal connection called tunN
is created. For instance, after activating a connection called vpntest,
I have:
- NAME UUID TYPE DEVICE
- vpntest 458856e6-8f0f-4dc6-82f2-dd72868252a0 vpn ens3
- tun0 1eb1dbe8-5678-4818-9adf-fb2dc01ed132 tun tun0
+ NAME UUID TYPE DEVICE
+ vpntest 458856e6-8f0f-4dc6-82f2-dd72868252a0 vpn ens3
+ tun0 1eb1dbe8-5678-4818-9adf-fb2dc01ed132 tun tun0
tun0 is created/removed after activating/deactivating vpntest and should
not really be saved, but I see netplan adding it in /etc/netplan. And
while doing so the plugin also reports some errors (I see these when
stopping the connection):
