Wendell Odom Q&A

posted in Interviews
by on February 20th, 2012 tags: , , ,

In December, I posted a thread in the Announcement forum asking for you guys to submit any questions you may have for distinguished author and CCIE #1624, Wendell Odom. I sent your questions to Wendell in January and got a quick response but have been a bit slow getting this blog post together. Well, here it is. Enjoy!

Wendell, first off, thanks so very much for sitting down and taking time out of your busy schedule to answer our questions!

How do you feel about Cisco fragmenting their certification paths and seemingly making a certification discipline out of anything they can? Do you feel they’re playing a sort of “catch up” to quickly ratify the newest industry buzzwords in a certification?

Thank you!

Networking Appliances Explained

If you’re new in the networking field and are faced with a complex network design, or are asked to design one, it can be a difficult task understanding what everything does. The certifications don’t cover it all: there’s so much more to networking than just routers and switches.

Therefor: an explanation about various appliances you’ll likely meet or need in a company. An appliance is a device that performs a specific purpose. Most simple example is a router: it’s actually a computer, but it can only provide routing. Here’s a list of other common devices:

Improving the Routing Table in an OSPF Network

OSPF Network

The topology above is an example network, consisting of four OSPF areas (one backbone, area 0) and one external EIGRP area. I’ve set up an IP addressing scheme using 10.0.0.0/8 for OSPF and 172.16.0.0/12 for EIGRP. In case you didn’t notice, the second part of the IP address is the same as the area number (10.x.0.0 for area x).

Rsync On CentOS 5.6

Just a quick blog about Rsync on A CentOS 5.6 box. I’m currently using Rsync to backup our Samba Server – all 500 Gigs of it!!

It’s going to take a few days but it will have an exact replica of the Samba server on the Rsync server and you don’t have to have any clients installed on other machines for Rsync to work. All you need is administrative credentials on the machine you are going to Rsync with.

Once I’ve figured all of this out, I will be setting my Rsync box to start backing up automatically every night (full backup) and also, when a file is changed on the Samba Server. I’m going to try and figure out the latter as I haven’t figured out how Rsync will be able to detect that a file has changed or been removed, etc. Once I have done so though I’m sure it’s going to be very handy, also I’ll be setting the Rsync box to backup all of the the user areas and profiles held on the DCs and also the users folder on the PCs.

A CCNA Security Exam Experience

posted in Certifications, Education
by on September 8th, 2011 tags:

In northern South Carolina, Wednesday morning dawned clear, temperate, and only lightly windy. Overall, it was a beautiful day for typically muggy August. My morning was spent reviewing for the exam. I went through the Cisco Exam Guide, picking out and mentally rehearsing lists and technology characteristics, defining key terms, and reviewing practice test questions.

At a quarter till 2, I left for the test center, nervous and excited. The building that contains the test center is a nondescript and plain looking installation overlooking a hill adjacent to the interstate. The first floor is a computer training center, the fourth, a local news channel, and the second is vacant.

The most interesting part of the building is the third floor. It is there that Cisco has its international Small Business Support Call Center that employs scores of CCNA and above certified support engineers. They handle and troubleshoot all Cisco Small Business products and most VOIP products in North and South America and the Philippines. The call center has a high employee turnover rate, but those who stay and excel there are very knowledgeable, helpful, and very good at what they do. I greatly enjoy being able to talk to them.
