Implementing Training Ideas

Jacob Stabl — Wed, 21 Jul 2010 16:25:19 +0000

After coming back from Cisco Live and then going on vacation to Traverse City Michigan it is now time to start implementing some of the things I learned in Las Vegas. My two immediate projects are upgrading to ACS 4.2 and a more robust easier to use Syslog server.

ACS goals:

Migrate network equipment from using Windows radius services
Ensure correct PEAP implementation
Integrate ACS with Active Directory
Create level of authorization to allow team members certain rights on network equipment.

Syslog goals:

Move from current Windows solution to a linux syslog-ng solution
Capture to a MySQL database
Ease of migration and growth
Reporting on certain events from equipment
Give access to management on certain reporting functions

So that is what I will be working on the rest of July and some of August.

At Cisco Live! 2010

Jacob Stabl — Mon, 28 Jun 2010 21:26:29 +0000

Make sure to follow me on twitter @jacobstabl and also follow #cllv10 and @ciscolive for up to the minute on goings of fellow Networkers.

So far I have been to 2 sessions and the first one was very dry and full of power point. The second one I got a better understanding of the purpose of Nexxus switches in our network. The emphasis was on design of the product and not integration but that is OK.

Next session for today is Care and Feeding of EIGRP which I hope is awesome with design of Rosetta’s new building and full EIGRP implementation (we are currently using it but building group up will help).

CCNA exam scheduled

Jacob Stabl — Tue, 04 May 2010 15:36:49 +0000

I have scheduled to take my CCNA exam while at Cisco Networkers in Las Vegas this year. I am scheduled for July 1st so I need to get my butt in gear and start studying. Most of my studying is going to be with practice exams to get used to the style of the questions. Also I need to brush up on subnetting a bit.

Ubuntu 10.04 LTS Available Now!

Jacob Stabl — Thu, 29 Apr 2010 18:39:08 +0000

This morning I went to Ubuntu’s website and saw that 10.04 was not available in a production release and I was really bummed because I thought that April 29th was the release date.

To my amazement at 2:30PM EST I visited the site again and a production version is available to download!!!

Download Ubuntu here!

Time to start upgrading and installing this awesome release on all my equipment.

Will be at Networkers Live 2010

Jacob Stabl — Thu, 22 Apr 2010 03:43:14 +0000

Well I just heard word that I will be attending Cisco Networkers Live 2010! I am so excited, elated, and any other adjective you can think of! This is a huge deal for me to finally attend Cisco Networkers Live in my 8 year career of Cisco professionalism. So if you will be there let me know and I would like to meet up with some colleagues.

Just got my first CME working!

Jacob Stabl — Mon, 12 Apr 2010 16:24:48 +0000

I am pretty lucky where I work because we have a lot of good spare networking equipment running around the office. So I took it upon myself to build a fairly elaborate network for testing new ideas, production configuration testing, and everything else you would ever want to test.

ASA 5510
3550  POE switch
2811 router
1252 A/B/G/N Access Point
7911 IP Phone
7920 Wireless IP Phone
7975 IP Phone

So I took the time to use the 3845 as the CME for the network. This was a great learning experience on SCCP, phone loads, and general network routing. I would like to start learning some QoS on the switches and access points.

Recover a Cisco Router from Rommon

Jacob Stabl — Thu, 08 Apr 2010 14:00:49 +0000

Today I was playing in the lab and I was trying to put a new IOS on my router using TFTP. So I did the normal commands:

copy tftp://172.30.1.10/ flash:

Everything copied fine and checksum was good… so I thought. I reboot the router and it boots directly into ROMMON telling me that the IOS checksum failed. So after a bit of playing around I decided I need to put the IOS back on using TFTP and this is how I did it.

IP_ADDRESS=172.30.1.3
IP_SUBNET_MASK=255.255.0.0
DEFAULT_GATEWAY=172.30.1.1
TFTP_SERVER=172.30.1.10
TFTP_FILE=C3845-IPVOICEK9-MZ.124-20.T4.BIN

tftpdnld

That downloaded the IOS to the flash and the reboot the router with that IOS set as system boot. Saved my day!

Warning all of the above commands are case sensitive or you will get an error. Hope this helps someone.

This is so exciting! SharePoint 2010 will really increase adoption of this product and the capabilities will be such much greater!

Pastebin.com is Awesome

Jacob Stabl — Mon, 05 Apr 2010 18:44:05 +0000

I like spending time on IRC mostly in technical chat areas (#cisco on freenode) to see what others are talking about, struggling with, and see where I can give some input to help. Well I have found http://pastebin.com an invaluable tool for sharing configuration examples, coding examples and other types of text with other people.
Pastebin.com allows you to add text make it publicly or privately available, highlight syntax based on popular categories, expire your post after a time period, and quickly give you the ability to share.
My only suggestion is to come up with a clever way to enable file comparison online.

**Edit: On my idea of a nice online file comparison here is one a good friend of mine created. http://comparemyfiles.com

I will talk to him maybe he can use some of the concepts of Pastebin on his site.

Google Fiber Application

Jacob Stabl — Fri, 26 Mar 2010 19:41:11 +0000

I am trying to get some feedback from those of you have applied for the Google Fiber for Communities Project? Most of all interested in the videos or stories you have wrote on your communities to help Google choose your residence as the best place in the world for fiber. I live in a rural area with many people not as interested in technology as I am. I full-heartily believe that local school systems are an expression of the communities beliefs in technology and the importance it plays in a day to day life.

Let me know in the comments.
