Bug in wireguard configurations parsing

[meyergru]

I saw this error in my wireguard log after upgrading to 25.1:

Code Select Expand

2024-11-02T12:41:43 Error wireguard /usr/local/opnsense/scripts/Wireguard/wg-service-control.php: The command '/usr/bin/wg syncconf 'wg0' '/usr/local/etc/wireguard/wg0.conf'' returned exit code '1', the output was 'Name does not resolve: `xxx.yyy.de:6010' Configuration parsing error'

The corresponding line in the "Peer" section of /usr/local/etc/wireguard/wg0.conf is:

Code Select Expand

Endpoint = xxx.yyy.de:6010

This configuration has not been hand-edited, it was created via the web UI.

It means the DNS lookup failed at the time syncconf was executed.  It's not really a syntax error, just a fatal error trying to convert DNS to IP because most of those DNS-in-the-system things are only ever resolved once and then static IP addresses for the rest of their lifetime.


Cheers,

Ah, correct. It only looks as if it was the port...
