Wireguard error when polling

[michmoor0725]

Receiving the following output when polling via the LibreNMS GUI

wireguard:1:Script returned exception: Command Execution Error: 'Command '['/bin/wg', 'show', 'wg0', 'dump']' returned non-zero exit status 1.'

command works without issue

root@libreNMS:/etc/snmp# wg show all dump
wg0 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx= xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx= 41073 off
wg0 xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx= (none) 1.1.2.2.2:51821 192.168.50.0/24,192.168.3.0/24,192.168.15.0/24,192.168.70.0/24,10.30.1.0/24,172.26.0.0/24,192.168.69.0/24 1702879153 8076598016 2675459028 off

Do you have SELinux running? If so, you'll probably need to install a custom module to permit snmp executing the script.

# getenforce
Enforcing

Otherwise, it may be a permissions issue. I get a failed execution if I run the command as an unprivileged user:

$ wg show wg0 dump
Unable to access interface: Operation not permitted

I am on Ubuntu 23.10

The problem seems to stem from an incorrect parameter being parsed. I am running the script as root and there is an error string?

root@libreNMS:/etc/snmp# ls -ltrh | grep wireguard.py
-rwxr-xr-x 1 root root        9.5K Dec 18 00:19 wireguard.py


root@libreNMS:/etc/snmp# ./wireguard.py

No, an empty error string and an error 0 indicates that there is no error.
