PHP 8 doesn't load mibs from /usr/share/snmp/mibs on RHEL 9.5

[Rex Maughan]

Hi,
For whatever reason PHP 8 isn't automatically looking in /usr/share/snmp/mibs for the MIB files like PHP 7.2 did.

PHP Warning: snmprealwalk(): Invalid object identifier: ipRouteMask

Any solutions for this?

Hey, by default, Net-SNMP does not load MIBs unless explicitly configured. Enabling MIB Loading in the Net-SNMP Configuration may Help:

To enable automatic MIB loading:

--> Edit (or create) the SNMP configuration file:

sudo nano /etc/snmp/snmp.conf

Add the following line:

mibs +ALL

• Save and exit.

Restart PHP or your web server:

sudo systemctl restart php-fpm

sudo systemctl restart httpd # If using Apache

sudo systemctl restart nginx # If using Nginx

Hi, You can try this: may help.

Set Environment Variable (for CLI PHP)


If you're using PHP CLI or scripts run via cron, set this environment variable before running your script:

export MIBS=+ALL

You can place this in /etc/profile.d/snmp.sh or within your PHP script using:

-> php

putenv('MIBS=+ALL');
