Cisco Wireless AP – VLANs and Multiple SSIDs Part 2

by on Jul.07, 2010, under Cisco, Sys Admin, VLANs, Wireless

Introduction

UPDATED 2010-11-23: There were a couple of typos in the code & a few lines in the wrong order. Thanks to Vic for letting me know about them.

Hopefully after reading Part 1 you have a general idea of what is going on. In this part we will do the configuation needed on CS1 and start to configure wlan1. I strongly recommend connecting via the console for this but it should be possible (if you are careful in which order you enter the commands that you could do this over ssh/telnet). During this period wlan1 will be unavailable to the users but wlan2 will be running fine so they shouldn’t notice any down time.

Cisco Wireless AP – VLANs and Multiple SSIDs Part 1

by on Jul.07, 2010, under Cisco, Sys Admin, VLANs, Wireless

Introduction

The purpose of this document is to explain how to setup and Cisco Aironet 1130ag with two SSIDs one for internal users which will authenticate via a radius server and the other for visitors that will use a wpa pass-phrase and will restrict users to Internet access only. This has (hopefully) been written in such a way that even someone with virtually no knowledge of Cisco should be able to read it and deploy a system successfully.

I should add at this point that I am not a Cisco guru in any way shape or form (though I am intending to get a CCNA & CCNP). So (I got my CCNA on the 20th August 2010) If you are and are reading this and happen to notice any bits that could be done better or are just plain wrong please leave a comment.

This is all based on some work that I have done recently, so I’ll give an example infrastructure and match the config to that example.

Useful Scripts

Intro:

This section contains the scripts I use to quickly redeploy the nodes. The “Post Script” could be improved a lot and also made more generic, however I’ll leave that as a task to the user, I may update it at some point if I have a need.

Infiniband cluster Part 1

by on Mar.13, 2010, under Linux, Servers, Sys Admin

Overview and installing the operating system

Intro:

To facilitate testing of our software and so that support can model possible customer environments I was tasked with setting up a cluster with infiniband. I was excited as the system was a Dell PowerEdge blade cluster (our 1st blade system) and we have never used or deployed infiniband (this would be our 1st infiniband system), in fact other than a basic “we have heard of this and know (very) roughly what it is” no-one in the group had any real knowledge of it. After a few hours of searching the deepest recesses of the Internet I had a limited understanding of how to setup the system. I know how irritating it is to have to read the crud in order to find that wee gem of info so from here on I’ll mark the paragraphs of the article so those of you wanting to “just get it done” can skip them.
