I wrote my own network latency monitoring agent in Go

For a while I had used Smokeping to generate pretty graphs of network latency between various hosts on my network. The downside with Smokeping was always getting it working. Did I configure my webserver just right? Did I remember to save the webserver configs so that the next time I set this up, things just … Continue reading I wrote my own network latency monitoring agent in Go

From 0 to an OpenBSD install, with no hands and a custom disk layout

I was hoping with my past posts on this topic, I would have enough examples to just copy-and-paste along to configure my Gitolite+Nagios monitoring setup. Not so true.

Stack it up: KVM, VLANs, Network Bridges, Linux/OpenBSD

I’ve had some free time and a desire to break stuff on my network at home. I wanted to fix my home network’s topology to more correctly split up my wired (DHCP), wireless (DHCP) and server (statically-configured) subnets. At a high level, I had to create a server subnet, create vlan’s on my layer-3 switch … Continue reading Stack it up: KVM, VLANs, Network Bridges, Linux/OpenBSD
