How to install Quagga on Centos 6.5

centosNamed after an extinct sub-species of the African zebra, Quagga is a fork of the GNU Zebra project routing software package,  which was discontinued in 2005, providing implementations of OSPF, RIP, BGP, and ISIS for *nix based systems.

Quagga can be used to turn your *nix system into a software based router, however it is more typically used as route server in an eBGP peering environment or as a route reflector in iBGP implementations that are not fully meshed. Continue reading How to install Quagga on Centos 6.5

Null route IOSXR Python script

Python-logo-notext.svgIts been a while since my last post, mainly because I have been bitten by the Raspberry Pi bug. As a side effect  of this I have been trying to learn Python to implement all the cool things the Raspberry Pi can do. I haven’t touched any programming languages since i was a student and barely scraped through Software Development 1, mainly because at the time I had no interest in C++, preferring micro controllers like the PIC and Intel 8051 where I could physically see the results of my code (making an LED blink is insanely satisfying).

GNS3 and IOU remote server install on Centos 6.5

gns3_icon_256x256I recently got a new laptop at work. It has one major downside, it only has 4GB of RAM which is soldered straight into the motherboard and therefore can not be upgraded. Also 500MB of the RAM is reserved for the GPU, so I only have about 3.5GB of useabe RAM. This is fine for running my day to day applications for work, but does not leave much wiggle room for running GNS3.

Luckily I work for a hosting company and we have quite a few servers lying around doing nothing. I managed to get hold of a decommisioned server with 2 quad core processors and 48GB of RAM, perfect to run a remote GNS3 server on. We mainly use Centos and since it is not an OS I am familiar with (I mainly use Ubuntu) I decided to give it a go and try something new. In this post I will run through the steps I went through to get GNS3 sevrer running on Centos as well as setting up the GNS3 GUI to connect to the remote server. Continue reading GNS3 and IOU remote server install on Centos 6.5
