Bash Script – Move Files into Subdirectories Based on Modified Date – OR – Moving Ntop Netflow Dumps into Subdirectories by Date

In a busy network environment, it is critical to have some form of network monitoring on all your servers and equipment. Network monitoring comes in many different forms and flavors, whether it be to monitor critical system services and applications via SNMP, WMI, or some proprietary third party software, or just generically pinging some devices to make sure they are up.

Nowadays, it is getting more and more necessary to dig deeper to be able to track what end users are doing and what websites they are visiting and this is where the Cisco Netflow comes in handy. Essentially, netflow allows us to peer down into the network traffic streams and give us vital source, destination, and protocol information coming to and from our network hosts but isn’t quite as storage intensive as doing a full fledged pcap dump, which makes historical accounting of this data a whole lot nicer.

Ubuntu – Icecast2 Startup Script with Ices2 Support

Recently I set up an Icecast server to be able to stream music on hold to my Asterisk servers at work. Here is an updated init script for Icecast2 that adds support to start the Ices2 source client at the same time. For streaming audio from a playlist with Ogg support, Ices2 is a good candidate. For streaming audio from an mp3 based playlist, have a look at Ices0 that can be downloaded on the same site. There is also an array of different Icecast source clients to choose from here. This just happened to be the first one that I tried out. I ended up bastardizing the code somewhat to make it conform to my own personal preferences by using functions and what not to make it all pretty like. I also chose to run Ices2 as the same user as the icecast user, so you would have to update any permissions on the Ices2 directories and config files as needed.

PHP – Simple PDO Class for Connecting to a MySQL Database

Here’s an extremely basic, reusable PHP and MySQL based PDO class for easily connecting to multiple database servers simultaneously within a script without having to go through a bunch of hoopla. Tidbits have been pieced together from the following sources with a little tweaking of my own (such as the ability to have default database values or to pass them as arguments):

VBScript – Get a Folder/File Size or Verify That a Folder/File Exists

Here are some snippets of VBScript I pieced together from various sources out on the web to be able to find the size of a folder or file or check that a folder or file exists. This is pretty handy because it also works for UNC path names or files and folders out on network shares, as long as your user has permission to access that path.

MySQL Script – Alter/Convert All Tables in a Database from MyISAM to InnoDB

Pieced together from various tutorials on the web with a lot of my own additions, here is a snippet of SQL that will alter or convert all tables in a database from “MyISAM” to “InnoDB”. As long as your MySQL user account has privileges to create stored procedures, all you have to do is simply edit the @DATABASE_NAME variable at the top of the script and run it in PhpMyAdmin if you’ve got it. Enjoy! Continue reading “MySQL Script – Alter/Convert All Tables in a Database from MyISAM to InnoDB”

Batch Script – Ribbon UI Customization: Take Ownership and Change Permissions of the CommandStore Subkeys in the Registry

This is just a follow up to my experiences customizing the Ribbon UI icons in Server 2012 and where the path has taken me thus far. After many hours of research and development and a lot of head scratching, I’ve written several posts on how to disable the different icons in the Ribbon UI which requires the adding or editing of keys in the CommandStore section of the registry for Windows Explorer. For more information on how to disable the icons, see this post.

My whole goal as of late was to be able to add these registry items to the RDS server’s GPO to be able to deploy these settings to all 7 of my RDS servers but then I found out you can’t take ownership of the CommandStore subkeys with the local “SYSTEM” account. Yet another deliberate Microsoft setback meant to discourage people from editing the Ribbon UI, oh well, fuck ’em. I’ve encountered so many problems with this RDS server project it is unreal and this was just icing on the proverbial cake.

Bash Script – OpenMCU-ru Service Monitor -OR- Monitor and Automatically Restart a Service Upon Failure

I threw this service monitoring script together because occasionally the OpenMCU-ru process in the developmental versions can crash out on my Ubuntu Server from time to time, so I wanted it to auto-restart. The script could easily be modified and used for any other service you like, but it was written specifically for OpenMCU-ru and Debian based operating systems.

There are two pieces to this puzzle (which makes for an awfully pathetic and simplistic puzzle), the “/etc/init.d/mcu-monitor” startup script to run the monitoring script as a daemon and the “/usr/local/bin/mcu-monitor.sh” monitoring script itself, both are fairly simple and straight forward.

Batch Script – RDS Start Menu Application and Taskbar Shortcut Removal Tool

Customizing or locking down a new server for Remote Desktop Services in a Server 2012 environment can be quite a time consuming and daunting task. Countless hours will be spent setting up Group Policies, testing them, and deploying them. But far worse than that, you will waste massive amounts of time researching for jacked up ways to do simple things, such as unpinning items from the Taskbar and customizing the Start Screen.

In the past, I had already configured a company wide Group Policy for our old 2003 Terminal Server environment and it was simple and easy. No guesswork, no crazy workarounds, shit just worked. The Group Policies covered almost every scenario or task needed to lock down a server but unfortunately, that is not the case any more.

It seems Microsoft has made the process of doing pretty much anything ridiculous and overcomplicated. As a side rant, we (the world) desperetely need a good open source solution for a thin client type environment with something that mimicks Group Policy. I know I’m not the only person out there that would love to give Microsoft the old stink finger once and for all! I for one am tired of sitting and watching companies succumb to the endless money pit that is Microsoft licensing. Where you at Linux Devs?

Anyhow, I decided to write this script for a lot of shortcomings I’ve encountered along the way. One of which that I want to gripe about is that resorting to changing file permissions to remove shortcuts is just plain fucking retarded and redirecting all of the user’s start menus to a network share seemed like massive overkill to an already complicated scenario. On top of that, I had 6 separate Remote Desktop servers to fully setup and configure so I needed to streamline the process a bit. Suprisingly enough, my solution relies solely on batch scripting (and a little makeshift VB).

Enough chit chat, the script is extremely well documented so here are the highlights/features:

  • Removal of the Server Manager and PowerShell links in the Taskbar
  • Ability to backup the All User’s and Default User’s Programs directories to a zip file
  • Ability to copy the All Programs Start Menu shortcuts to a list of administrator or power user profile directories
  • Customized list of applications to remove from the Classic Shell Start Menu or the Windows Start Screen
  • Deleted Start Menu Program entries go into the active user’s Recycle Bin and can be restored if necessary
  • Remove System Tools, Accessories, Accessibility, Administrative Tools, Windows Store, PC Settings, Control Panel, Run, Command Prompt, and PowerShell shortcuts from Menus

:: RDS SERVER 2012 CUSTOM START MENU AND TASKBAR SHORTCUT REMOVAL
:: Author: Nathan Thomas
:: Date: 02/11/2015
::
:: This script should be ran on the RDS server after your server administrators have already
:: logged in at least once so that they get all the shortcuts they need (otherwise you will 
:: need to manually copy them later on) but before your end users log in for the first time.
:: In addition, it assumes you have not already made changes or any customizations to the
:: All User's or Default User's Start Menus profiles and that you have already installed all
:: of the applications that the server will be running. Please note that if you decide
:: to install software after you've ran the script, you will manually have to remove that
:: program from the All User's Start Menu folder and copy it to your administrator profiles
