Monitoring network traffic with jnettop

by on Mar.11, 2011, under Linux, System Administration

Just a quick post about jnettop, a tool I find really useful for monitoring network traffic to see what other machines a machine is talking to, and how much traffic is being sent/received between them. (It also includes traffic going via the host you’re running it on, so very useful for firewall/gateway machines.)

Jnettop is a traffic visualiser, which captures traffic going through the host it is running from and displays streams sorted by bandwidth they use.

Useful stuff.
