CiscoLive 2017: Still Learning, Still Having Fun

by on Jul.07, 2017, under Networking, Technology

Cisco Live was in Las Vegas again this year, and it was hotter (in more ways than the weather) than last year! I learned quite a bit and had a lot of fun. But fair is fair: There are things I would like to see changed. Still – if you’re a networking professional that touches Cisco equipment, going to Cisco Live is a benefit you can’t ignore.

A Day With Apple AirPods

by on Mar.01, 2017, under Cell Phones & Providers, Technology

My loving wife, with her birthday fast approaching, caught word of these things and wanted a set for herself. I of course figured I’d get us both a set and see what they were like.

I was waiting for my Pebble Time 2 Kickstarter reward when the word came down: Pebble was stopping all hardware production and being sold to Fitbit. In a moment of weakness I spent way too much money on an Apple Watch. Here’s my review after one day.

deny ip any any: What You Need On An “in” ACL For DHCP And HSRP To Work

by on Apr.28, 2016, under Networking, Technology

It’s been my experience that “ip access-group <acl> in” is rarely used. Most of the time, people look at the “out” form of the command. In this post, I will explain how to view the different directionality of the “in” vs “out” and then review the issues that you can encounter with respect to DHCP and HSRP when it comes to ending an “in” ACL with a “deny all” at the end.

The Network As A Symptom: Subnets

by on Apr.21, 2016, under Networking, Technology

Related to my previous post about “The Network As A System”, during my time on call, I got another request that stated: “I need a port opened between 10.0.0.24 and 10.0.0.56. I know they’re on the same subnet, but I’m getting timeouts when trying to connect between them.”

The thing is, they weren’t on the same subnet.

The Network As A Symptom: DNS

by on Apr.21, 2016, under Computers, Networking, Technology

We have an on call rotation at $JOB where, for a week, a given engineer is responsible for responding to after hours phone calls as well as tickets and ACL requests. During a recent turn of mine with the football, I got an ACL request that didn’t make sense, and after working it through with the DB Admin that made the request, I figured I’d write this. It’s sad that it’s probably mostly networking people that read the blog, because they already understand everything this will explain. It’s the DBAs, Developers, and other IT support personnel that could benefit from what I go over here.

UnifiedTrees 1.0 Cacti Plugin: Major Update

by on Feb.16, 2016, under Networking, Technology

$JOB’s Cacti multi-server infrastructure has been running fine on Cacti 0.8.8b and UnifiedTrees 0.8. However, Cacti 0.8.8f is out and the trees are done quite differently. It’s time to update $JOB’s Cacti infrastructure and to make UnifiedTrees compatible, it had to undergo some major changes.
