From e05d878f94a88885bcd12aeaab00d23be6fb10e2 Mon Sep 17 00:00:00 2001 From: Christian Manivong Date: Fri, 19 Jun 2026 21:35:30 +0200 Subject: [PATCH] fix: implement _action_fix_snmp for OpenWRT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The method was called but missing — always raised AttributeError, so Fix SNMP did nothing on OpenWRT devices. OpenWRT's default firewall (fw4) policy-drops everything except the ports explicitly listed in the management zone (SSH/HTTP/HTTPS/ICMP). SNMP (UDP/161) is not in that list, which is why snmpd runs but is unreachable from outside the device. Fix adds a persistent UCI firewall rule for UDP/161, reloads fw4 immediately, verifies snmpd is running, and probes locally if SNMP client tools are available. Returns success so callers can clear the snmp_no_data warning.
