Cisco Firewall

John : April 5, 2011 10:28 am : Technology

So 2 weeks ago Cisco decides to release a new version of their ASA (Adapted Security Appliance) Firmware, the ASA is more commonly known as a Firewall. I use a couple ASA’s at work to help keep control of the network and of course to provide some protection from hacker and other such bad guys.

The new firmware is a major change and instead of being named an upgrade to ver 8.x, they should of just gone with a new version level, say 9.0, because it has major changes and all the rules we’ve been using to set up ACL’s no longer work. Since this upgrade has so many changes, you also have to upgrade your hardware to 2 gig of RAM, humm, wondering if they got this idea from M.S.

Intro to Networking

John : July 13, 2010 10:47 am : Technology

With the growth of the Internet and lower cost of PC’s, doing a comparable summary on what to buy i.e. PC -v- Mac is almost redundant and irrelevant these days. Add to that the growth of home networking so mom, dad, and the kids can all share the same printer and Internet connection, I figured it’d be worth adding a little breakdown on networking in general.

This is not an all inclusive structure of computer networks, its a simple basic summary. Todays design of networks are still as they were 10, 15, even 20 years ago, but the need for security has increased and the means to get your different systems connected has changed, slightly. Your systems, Linux, Windows XP, Windows Vista, Windows 7, and MAC’s all have different ways to join a network. Heck, even the different versions of an OS (Operating System), such as Windows 7 Home Edition -v- Windows 7 Pro are slightly different do to the structure of each one and I strongly suggest that you research the networking ability and limitation of each system you want to network.

DOS: Advanced

John : May 20, 2010 10:38 am : Technology

What Are Batch Files?

Batch files are user-written "mini-programs" in which each line is a DOS command. Such files are processed line-by-line, executing commands that have been batched together. Most of the time batch files are created to avoid having to type in a series of commonly-used commands. A simple example might be the following:

DOS: Intermediate

John : May 20, 2010 9:23 am : Technology

Repeating or Editing a DOS Command

You can use the function keys on your keyboard for re-entering DOS commands without retyping them. Use F3 to re-display the previous commands all at once, or use F1 to re-display the command one character at a time. To execute the re-displayed command, hit <Enter>.

To delete text from a previous command, press F1 until you reach the text you want to delete. Next, press the <Del> key to remove unwanted text one character at a time. Then press F3 or F1 to display the rest of the command. Press <Enter> to execute the modified command.

To add text to a previous command, press F1 until you reach the place where you want to add text. Next, press the <Ins> key and enter the new text. Then press F3 or F1 to display the rest of the command. Press <Enter> to execute the modified command.

DOS: Getting Started

John : May 20, 2010 9:04 am : Technology

What Is DOS?

Today, the DOS OS is basically null and void as a stand alone OS. However, when you click on the “Run” option in Windows or type “CMD” in the windows search box on Windows 7, your basically going into a DOS Prompt command interface. From this you can do lots of things with your system, so here’s some limited information to help you along. I’ll have 3 sections to this, just like I did with the Unix info, of course Unix/Linux is still growing and developing, whereas DOS is pretty much stagnant these days.

The Utilities Down and Dirty

It should be noted that this is just a quick reference guide to some of the more common utilities.  This list is by no means all encompassing, nor inclusive.  Descriptions of the utilities are brief.  For detailed usage and information, use the man utility.

Unix / Linux: Intermediate

John : May 19, 2010 4:51 pm : Technology

    In this section we will be looking at a host of items concerning Unix.  The first section will deal some more with command line sytax and usage, and quoting characters.  The second section will deal with setting file permissions on files and directories and a little bit of relative paths and links.  The third section will deal with more utilities that you can use in your daily workings with Unix.   Be sure to review the first basic lessons of file management and basic command line syntax.  Now, let’s get started.

Setting up WordPress

John : May 12, 2010 6:00 pm : Technology

So here I’ve been spending lots of time setting up my new web presence with a WordPress site. Lots of configuration options with widges and plugins, I think I’m spending more time trying to figure out all the dang nabbit widges then I am coding the site. Man I miss the days of simple HTML files with some simple JS or CGI scripts.

Anyway, I need to learn this for the Iron Dog site. It was built a bit to cumbersome (in my humble opinion) for the need the Iron Dog has. A nice site, the Iron Dog but a maintenance nightmare, especially for non or limited tech folks at the office.
