ASA Firewall Class

This week we are going to be going to Omaha, NB for an Cisco SNPA ASA course.

We purchased 3 new ASA 5510 firewalls for the purposes of the class. Before we left I reconfigured the 3 firewalls to have the latest two versions of the Cisco IOS on them and the web management environment for the two different versions.

For this purpose I had to use TFTP to upload the software to the firewalls and configure the firewalls to run the appropriate version of the IOS before we started the class.

Looking Ahead

Browsed e-bay today to find out how much it would cost me to grab a TDR or an occilliscope online.

Things were a little bit outside of my current price range.

More Research

Found some great stuff online tonight. There were two great examples of cheap TDR's that I found.

These are booth good ideas and they are really cheap to build. Need to do some more looking to see if there is a better way.

Research

Continued on the path of research. Here is a basic listing of the things that I found on Wikipedia so I can reference back to them.

Progress

This week I did several things in the area of the applicable research:

• I moved all of my work to a consolidated notebook on my server at home.
  
• I installed and tested Multisim and Visio so that I can create and experiment with some basic designs
  
• Built my To-do list for the next few weeks
  

Next week I plan on beginning the active research and trying to build examples of some of the circuits that I've found online to see if this will work at all.
