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...

iACLs; A Service Providers Best Practice on your LAN

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...

What does eating at Vegan restaurant and attending a four day conference in Waukegan on the external factors influencing paint drying times have in common? Let me be rude here and answer that question with another question; What is...

Pissed Off About Poor Quality

I am pissed off. I am not sure what at so I thought I would start writing and see if I can figure it out. I know who I am pissed at and that is Hewlett Packard (HP). It's not a competitive thing either. I love the competition between...

Port 666

One Cool ISO: Fully Automated Nagios

TV Dinners. Not only is this an ultra cool song by ZZ Top but on the surface of the twenty year turkey in a thirty year old skin it should be a perfect meal for folks on the go. The majority of your food groups are all there, cooked...

Delay Tolerant Networking

Three Better Ways of Doing Networking That We Ain't Doin'
