Networking

I knew about a MacOS task bar plugin called Anybar, which basically draws an icon on the task bar to which you can send behaviors with a simple nc command. Naturally, someone cloned it for our beloved Free Unices environments, and it’s called somebar.

I am sometimes in places with weak network, and I like to see at a glance how is my connection doing, somebar seemed the perfect tool for the task.

In the past month, it’s the second time I’m being bitten by FreeBSD in the networking field.

First time with my own gateway, I had this weird behaviour where machines on a different VLAN than the main one would use the Internet at full speed but would struggle to make any transfer from the main VLAN.

Turns out this was a tcp segmentation offload issue, which seems to cause so much problems it is disabled by default in some appliances.
