# 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.

### Compatibility ###
Scripts will be kept backwards and forwards compatible with LANforge
releases as much as possible.

### Requirements ###
The perl scripts require the following perl packages to be installed. Most of these
perl packages are available through your repository as `.deb` or `.rpm` packages. 

| Perl Package       | RPM              | Required       |
