= UNIX Networking CLI Commands =

All UNIX systems and their derivatives (i.e. the various flavors of Linux) have a built in ''command line interface'' or ''CLI''.  

Since all of the compute resources in GENI run some *nix flavor, it is important to be comfortable using the command line.

Some skills and command you should familiarize yourself with if you aren't already:
  * the configuration of the interfaces on your nodes (`/sbin/ifconfig`)
  * testing connectivity (`ping`, `traceroute`, `nc`, `iperf`)
  * collecting and analyzing networking traffic (`tcpdump` and ''wireshark'')
  * listing and manipulating your IP routing table (`route`)
  * determining the hostname of the current machine (`hostname`)
  * listing network connections (`netstat`)
  * testing connecting to individual ports using telnet (`telnet`)
  * 

Google will help you find many resources to learn about these topics.
