My Home Lab, ESXi 5.5 Server Build, and The Logic Behind It All

Several folks have asked me about my home lab server build since I’ve tweeted a time or two about it. Here’s what I’ve built so far, and some of the logic behind my choices. The Purpose Of My Lab I am working on network virtualization, automation, and software defined networking tools.

Working From Home

Unless I’m on a plane, these days I work from home full-time. I know that sounds like a dream to some, but I think working from home is not for everyone. Here’s a few things I’ve learned along the way. Self-discipline To successfully work from home, I’ve found that being organized, self-motivated, and conscientious is a requirement.

Moving BIG-IP VE LAB Edition from VMware Fusion to ESXi 5.5

I moved my BIG-IP VE Lab Edition VM from VMware Fusion on my Mac over to VMware ESXi, now that I’ve built a full ESXi 5.5 host to lab with. Here are my notes, as it was overall easy enough, but I did it wrong the first time. Maybe I can save someone a little time. Or better yet, someone can respond in the comments with an even better way to accomplish this. VMware provides a vCenter...

Junos SNMPv3 – Config Baseline for All OID Access Using USM with Authorization & Privacy

SNMPv3 is the successor to the more commonly deployed SNMPv2c. While the underlying structure of MIBs & OIDs are not impacted by v3, the way those objects are accessed are. While SNMPv2c offers read-only and read-write community stringsĀ (essentially passwords) to secure access to the device MIB, the data flow was in plaintext, easily readable by anyone in the data path with a sniffer. SNMPv3...

Abstract All The Things -or- Why CLIs Are In My Way

Network engineers tend to live at the command line interface (CLI). We learn them. We know them. After a long while of using them, the commands required to get certain tasks done are second nature. I’ve configured so many access-lists, interfaces, routing protocols, VLANs, link aggregation groups, QoS policies, and spanning-tree topologies on Cisco gear that my fingers are on auto-pilot...
