LANforge Perl, Python, and Shell 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.

LANforge CLI Users Guide: https://www.candelatech.com/lfcli_ug.php

The LANforge CLI Users Guide is a good place to start for understanding scripts

LANforge on system cli help and cli command composer

The LANforge has an on system help / system query, when on LANforge browse to http://local_host:8080

The LANforge has an on system cli help and cli command composer http://local_host:8080/help

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_associate_ap.pl	LANforge server script for associating virtual stations to an arbitrary SSID
lf_attenmod.pl	Query and update CT70X programmable attenuators
lf_firemod.pl	Query and update connections (Layer 3)
lf_icemod.pl	Query and update WAN links and impairments
lf_portmod.pl	Query and update physical and virtual ports
lf_tos_test.py	Generate traffic at different QoS and report in spreadsheet
lf_sniff.py	Create packet capture files, especially OFDMA /AX captures

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

LANForge Monitoring

From LANforge cli on port 4001 do a 'show_event' to see events from LANforge

Compatibility

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

Installation

These scripts call each other and rely on the structure of this directory. To use these scripts in other locations, such as your laptop, either copy the entire scripts directory or do a git clone of this repository. Just copying one script to a separate directory is going to break its requirements.

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
Net::Telnet	perl-Net-Telnet	Yes
JSON	perl-JSON	Yes, for JSON parsing
JSON::PrettyPrint	perl-JSON-PP	No, useful for debugging

Python3 Package	RPM	Required
Pexpect	python3-pexpect	yes
XlsxWriter	python3-xlsxwriter	yes, Xlsx output

Pip v Pip3

Please use pip3, we are targeting Python 3 with our scripts. If your pip/pip3 repositories have a difficult time connecting, it's likely that you are trying to download from pypi.python.org. This is a deprecated location. Please update using the pypi.org servers. Consider updating your ~/.pypirc file:

[distutils]
index-servers =  
    pypi  

[pypi]  
repository: https://upload.pypi.org/legacy/

As described on Python.org.
