ModSnmp Manual v3.15 - 13.4. Changing server settings
You may want to change some of ModSnmp's settings while it is running as a server. The simplest way to do this is to start an interactive copy of ModSnmp on the same computer, and use this to edit the settings file being used by the server copy:
Use → to load the settings file being used by the ModSnmp server.
Change the settings as required.
Use → to save the settings file being used by the ModSnmp server.
The server copy of ModSnmp will notice that the settings file has been modified and will re-read it.
Check the log output from the ModSnmp server to ensure that the new settings have not caused any errors.
