LANforge Perl Scripts

This is a collection of scripts and scripting libraries designed to work with LANforge systems. On your LANforge system, these scripts are typically installed into /home/lanforge/scripts. The LANforge/ sub directory holds the perl modules (.pm files) that are common to the perl scripts.

Commonly Used

The lf_*.pl scripts are typically more complete and general purpose scripts, though some are ancient and very specific. In particular, these scripts are more modern and may be a good place to start:

Name	Purpose
lf_portmod.pl	Query and update physical and virtual ports
lf_firemod.pl	Query and update connections (Layer 3)
lf_icemod.pl	Query and update WAN links and impairments
lf_attenmod.pl	Query and update CT70X programmable attenuators
lf_associate_ap.pl	Query and update wifi stations

The lf_wifi_rest_example.pl script shows how one might call the other scripts from within a script.
