First attempt at RIP


In this diagram, R1 was to act like a switch providing direct connectivity between R8 and R6. RIPv2 was turned on on all routers: R8, R10, R6, R7 and R9. 

Initially I had issues as I had not enabled Version 2. I also received a twitter suggestion from @packetmaniac to use no auto-summary.

I was using GNS3 and Dynamips to configure the above routers, and R1 was using the  NM-16ESW module, which from my understanding is just like having a switch within a router.

Advertising - or lack thereof

In the past, I have always created blogs with the sole purpose of generating revenue. This was to the extent that even before I had any decent content, I added advertising. Over the years the amount of revenue generated from said advertising was really minute.

So here is a new blog, and a new commitment: No Advertising on this blog. Ever.

First DNS Post

This is my first of many posts dedicated to DNS or the Domain Naming System. I have always been fascinated with how this interesting system works, delegating responsibility of particular domains to certain administrators and certain servers.

The beauty of this system is that its so great that most end users have little to no knowledge of the intricacies of this system as it just works.

One thing that people who register a new domain, or migrate a domain from one host to another might deal with the idea of propagation. This is basically the time it takes for information about the domain to update all over the internet and get back in sync. This can vary from nearly instant to 24 / 48 hours or even 72 hours in some rare cases depending on which DNS server you are connected to.

One resource that really helps in this situation is the toolbox offered by DNSstuff.com I would really recommend checking them out if  you deal with domains or need to test if the domain has been configured correctly.

CCNA 640-802

This is the first step in whats probably going to be a long and challenging journey to becoming a Network / Internet Administrator.

I have gotten a hold of a few CCNA textbooks, and setup a virtual lab environment using GNS3 / Dynamips.

Return to Google / Blogger


When I first started a few blogs, I did so at Blogger. Since then I moved on to shared web hosting and Wordpress blogs. I then took blogging to the next level and moved to Virtual Private Server solutions. Recently that has become a pain doing my own backups and Wordpress upgrades.

Which brings me back to Blogger, but this time around I plan on using my own domain.

I am striving to be an Internet Administrator / Consultant, hence the ia subdomain.
