Bash Script – Install HP Server Management Tools on Ubuntu Server

Here’s a quick and dirty, no-frills bash script to install the HP Server Management Tools on Ubuntu Server. As is, it will install the command line utilities to configure ILO and your RAID controllers. You can look up the other package names available for your distribution by examining the Packages file as in this example here:

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.
