Is Network Security a Dead End Career?
Hard to believe that I ever thought I would be sitting here wondering about the state of security as a viable career path. I have built my career up as a security dude/hacker for years, but lately I have been noticing a few things....
Prototyping 101
I love prototyping gear. That initial start up to check if what I designed works like I planned it to. The answer most of the time is NO, but that is a good thing. Many of the things I have developed have came about by trying to...
Starstruck
I remember when I was a younger kid zipping thru the hills of Tennessee, no matter where I was, I always tried to make it back in time to watch Happy Days. When the 45's started spinning and the theme song started, man that was a...
Is that a Cluster in your pocket or are you happy to see me?
High Performance Computing (HPC) is equal in coolness as your friends seeing you growlin' and prowlin' on a raked and piped out Harley on a summer day. To prepare for my CodeCave Spring cleaning session, I started looking at which...
Kickin' VAS with OpenVAS!
Twitter can be used for a bunch of useless, time killing things. Things like what a goober celebrity thinks of grooming a cat with a dog brush or the endless string of folks posting lines to songs. OK, I get it! you like Spandau...
Open Source Storage Options
I have said it many times before in this and other forums that I believe data center technologies are THE career path to get in right now for the future. Especially, if your background is plumbing....routin' n switchin' But man it...
A World Without Multicast

Me Versus QoS...Round 1...
Last week we were shooting a TechWiseTV episode on Telepresence. I refused to do this at first since there is a ton a crap out there on how cool it looks. If we do this show we have to go behind the scenes and not even show a...
Firewall Features that don't SUCK: Zone Based Firewall Policies
I was at the gym the other day, now before you jump to conclusions; I was just waiting on my son to finish his fencing class. He was learning how to sell stolen merchandise in Milwaukee... I was just sitting there minding my own...
iACLs; A Service Providers Best Practice on your LAN
When I first started working on Cisco gear back in the early 18th century, ACLs were one the the biggest deployment problems I ran into on a day to day basis. On my first day of being introduced to ACL's was also my first day of...
An Early Gift for MySQL servers
Trying to keep up with all of the possible attack vectors and decreasing your attack surface is like trying to eat Minute Rice with chop sticks. It's a full time job! I used to blame a lot of attacks on PHP because it deserves it. I...
How NIKTO saved my tail on a cold Wisconsin morning
Talking crap and pissin' folks off. These are a few of my favorite things - in a good way, of course! Not a type "A" win-at-all-cost jag-off like the folks you want to punch right square in the face at a sporting event. For me it's...

Cool IOS Feature: Random NetFlow
Does anyone out there remember the show, "The Fall Guy" with Lee Majors and one of my big time young punk kid crushes, Heather Thomas. The theme song was as popular as the actual show (especially the later seasons which sucked worse...
Overlooked VOIP Security Features
I am wanker when it comes to VOIP. I am not a huge VOIP fan. Nope. Not much at all. When I was growing up, phracking never really appealed to me. I remember tripping my first 5ESS and not thinking "that’s cool" but "so what". Kinda...
Manly Man IOS Features
If I was to write a movie script, on a Manly Man Sys Admin who would I use a base to draw from. It’s certainly not some of the total knobs that have been pushed on us by Hollywood casting agencies. Look how they had portrayed us with...
Port Scan Attack Detector PSAD
The fish just haven't been biting here in the Land of Cheese this year. So that has gave me tons more time in my lab geekin' and phrackin'. I was playing around in my lab the other day trying to build out a low to no cost SMB...
