Mikrotik Scripting – Array Push Function

Since the scripting language at the moment on Router OS version 6.13 is lacking in the array editing department, here is a simple array push function I created.

# Usage: [$arrayPush <$array name> <value> <key position to place value (0-n or -1)>]
# Input an array name, value, and the key position to push the value to. To push value to the end of the array, enter -1.
# If array doesn't already exist, you must declare the variable and set it to "" before calling the function.

Mikrotik Scripting – Function to Split an IP Address into an Array

If you are unfamiliar with Mikrotik networking equipment, do yourself a favor and check them out at mikrotik.com or routerboard.com. Mikrotik uses Router OS, a Linux based operating system. In my eyes, they are every bit as comparable to Cisco at a fraction of the price with an impressive and robust GUI. I’ve been using them in production environments for six years with outstanding results. What other networking equipment has it’s own scripting language? None that I know of. The CCR series of routers with up to 36 processor cores are unparalleled in performance and flexibility.

Bash Script – Move Asterisk Call Files into Spool Directory

After running into permission issues trying to get PHP’s shell_exec command to chown call files as the asterisk user(which only root can do), I decided to make this script.

As a side note, you should be able to get the shell_exec command to work using sudo by adding the www-data user to the sudoer’s file without a password but that wouldn’t work in my particular environment. The server I was working on was extremely outdated and didn’t even have sudo installed.

Add this to /etc/sudoers
www-data ALL=NOPASSWD: /path/to/script

The following code runs the script as a daemon. You will need to update rc to start this script at default run levels and also make sure to chmod +x this file to make it executable.

filename: /etc/init.d/mvcallfile

#!/bin/bash
# Move asterisk call file daemon startup script

Startup Script for OpenMeetings Open-Source Video Conferencing Server

/etc/init.d/openmeetings startup script for Ubuntu Server 12.04.2
OpenMeetings Version 2.0-INCUBATING

A few notes:
– Make sure to change path for RED5_HOME variable
– Make sure to chmod +x the init script
– This assumes openmeetings is running under a user/group with the same name
– This assumes you are using libreoffice (not openoffice) for the whiteboard file import service
