Running Docker on OSX and Other Fun Things

Docker on OSX

I have a friend who wants to test a tool I wrote in perl (yes yes, I know) but it seemed to me that it was going to be a big pain for him to have to install all the modules necessary to support it. And so, I thought, I had the perfect solution – I’d build a container with everything in it, and get him to run that instead. Simples!

Network Monitoring Videos from NFD8

I’ve had network monitoring systems on my mind recently as we’ve been looking to determine the right specification for a number of fiber taps and aggregation devices so that we can fulfill the needs of both the security teams (for Intrusion Detection Systems and similar) and the network team for packet captures and troubleshooting. In reality we’d probably like to be able to have a mixture of full time monitoring (so we can pull statistics, or ‘rewind’ to a recent event and see what was happening on the network) as well as on-demand packet capture so we could troubleshoot specific problems.

As networks get bigger and faster though, the task of monitoring gets progressively more challenging as the number of devices, the number of links, and the speed of links increases.

I was interested therefore when at Networking Field Day 8 this last week we had no less than three monitoring solutions presented to us, each taking a different approach. And so, in alphabetical order, here’s what was presented.
