Puppeteering with Puppet

So I’ve been a very naughty sysadmin recently, one of the things I intended to do early on in my new employment was setup some form of System Management as we have several Linux hosts. However truth be told I have never had a System Management system for Linux hosts (due to a lack of time to implement one) and due to a number of tight deadlines I’ve had to put this on the back burner and spin up servers for additional roles.

This road however will lead to ruin so I have put a stop to the random spinning up of hosts for anything other than testing until I get something in place to mange all the configurations centrally. The question for me was what to use, I’ve heard of both Puppet and Chef, but I have no experience of them. So after doing a bit of reading I figured I’d go with Puppet as it seems to have most of the bases I am interested in covered.

SCCM CDP to WMI version out

Sorry for the lack of progress until recently but I’ve recently had a lot of more important priorities in life so working on this had to go on hold for a little while. I am hoping in the next few months to release version 1.0 but as on now this is still experimental so should only be used in a lab environment.

Please use the ticketing system on sourceforge to report any issues and add feature requests.

You can get it here: http://sourceforge.net/projects/cdptowmi/


See here: https://sourceforge.net/p/cdptowmi/wiki/ToDo%20List/ (work in progress)

Setting up a Cisco network for video developers Part 2


Welcome to Part 2, this part will provide the background and current topology that is to be replaced, the real fun will start in Part 3. I know you are all impatient to get started configuring switches, routers and servers but I think that the design and the reasons behind the design are as important (if not more so) than the actual configuration. As always I know I am not perfect and all knowing so if from the background and the following tutorials you think I have missed something or could have done something better then please speak up, send me a message via the contact page or leave a comment.


NINet has grown since the last series and now has a floor of approximately 40 developers developing video solutions. The current solution was put together in bits and pieces and is resulting in poor performance and frequent outages. It must be stressed that this is a development network and as such cannot be locked down developers need to be able to connected unmanged switches (much to my irritation) and connect devices at will.

Setting up a Cisco network for video developers Part 1


This series of tutorials will be similar to my posts on a wireless setup, where I take a real world requirement of mine and fit it to a tutorial about NINet.org.


This series will take an existing flat topology with mixed switches running in L2 and convert it to a Cisco Switch Topology mixing L3 and L2. Then we’ll take a bit of step into the sysadmin side of things where we setup infrastructure servers to support the end users. At the time of this writing, in the real world, this network is up and running however the supporting infrastructure is a lower priority than other work items so it may take a while to filter through to here.

TFS Warehouse Cube Status via SOAP and Powershell

Well I’ve just been put in charge of managing our TFS infrastructure so here is the first of hopefully many posts around automating and managing TFS.

The attached script runs a SOAP query against the TFS Warehouse Cube and returns the jobs and their status and then either generates an HTML file or sends an HTML email with the results.

I recommend creating a directory called Scripts on the C:\ drive and setting the permissions so that only the System Administrator & User the script runs as can access the contents of the directory.

Scripted checking of SCCM Backups

This is a script that parses the smsbkup.log and outputs results (in html) and the relevant portions of the file to the specified folder. The idea being that the with a small bit of tweaking you could have the report hosted on  a webserver to check or emailed (there will be a post on emailing in Powershell later) to you.

This is best run from the central primary under credentials that have access to the other sites.

Note: The script requires UNC paths for the $fpath variable as it is expecting be be run remotely.

Note2: This script was written for SCCM 2007 and not for SCCM 2012, however thanks to one of my readers, Satish, the following should fix that:
if ($content | where {$_ -like "Backup task completed successfully*"}) {
if ($content | where{$_ -like "*SQL Backup task completed successfully*"}) {

Potential Dates issues with SCCM 2012 R2. Thanks to Marius for the update.
$cdate = $cdate.adddays($days) | get-date -format “ddd MMM dd”
to (this is probably US specific and will probably vary depending on locale)
$cdate = $cdate.adddays($days) | get-date -format “MM-dd-yyyy”

Deploy Centos 6 from VMWare Template

This is just a quick gotcha that I found ages ago then forgot about and then had to figure out again. Before you convert the VM to a template.

rm /etc/udev/rules.d/70-persistent-net.rules

sed -i ‘/HWADDR*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0

sed -i ‘/UUID*/d’ /etc/sysconfig/network-scripts/ifcfg-eth0



This also applies to SLES 11 SP2 (use /etc/sysconfig/network/ifcfg-eth0)
