====== Useful Programs ======
A list of those programs you only need once in a blue moon but can never remember the name of.

  * lsof - list all file handles. Can be useful when a filesystem won't unmount.
  * modinfo - describe module and arguments that can be provided
  * htop - top on steroids
  * atop - lists the most active processes based on CPU, memory, disk and network usage
  * iotop - lists io usage of programs.
  * duc - visualise disk usage

===== Networking =====

  * iftop - lists network usage by ip address
  * iptraf - similar to iftop but has a bit more functionality
  * nethogs - per process network usage
  * nload - per interface usage and console graph
  * ntop - not what you're looking for
