Ubuntu Server QOS Test

Running Ubuntu Server in Virtual Box in Windows can allow for some useful extra networking utilities. I was searching for alternative to ping -V since this parameter has been deprecated and found the Ubuntu ping command offered more. Assumption being that the VM is connected to a network where you need to test.

Using Ping -Q tos option (ie 0xB8) to send ICMP requests with DSCP 46 set.

Tip: Toggle through multiple TTY terminal screens using Alt + left or right arrow. Run ping from one window and TCPDUMP from another.
