1. The Network Capture Playbook Part 2 – Speed, Duplex and Drops

   In part one of the playbook series we took a look at general Ethernet setups and capture situations, so in this post (as in all others following this one) I’ll assume you’re familiar with the topics previously discussed. This time, let’s check out how speed and duplex can become quite important, and what “drops” are […]

2. Trace File Case Files: SMB2 Performance

Few people ever consider this an important step, but this is really where the analysis result can be heavily distorted if you’re not careful. During Sharkfest 2016 I talked about how important the capture process and it’s preparations […]
