Some useful command with iproute2

Feb 152013

As I wrote more than 2 years ago, the network tools (often referred as net-tools) ifconfig, netstat and route that should be familiar to anyone that has worked with a terminal, have been deprecated in favour of the iproute2 suite from some years.

iproute2 is intended to replace this entire suite of legacy Unix networking tools that were previously used for the tasks of configuring network interfaces, routing tables, and managing the ARP table, but which have not been developed since 2001.

You can find some examples of the usage of the iproute commands on my articles about:

– Policy routing
– Socket Statistics on Linux
– MAC Address Managment on Linux

And today I want to share with you some of the most useful commands that you can use with this “new” suite of commands and the translation of some old commands that we were all used to use on the terminal.

MAC Address on Linux

A Media Access Control address (MAC address) is a unique identifier assigned to network interfaces for communications on the physical network segment. Logically, MAC addresses are used in the Media Access Control protocol sub-layer of the OSI reference model.

MAC addresses are most often assigned by the manufacturer of a network interface card (NIC) and are stored in its hardware, the card’s read-only memory, or some other firmware mechanism. If assigned by the manufacturer, a MAC address usually encodes the manufacturer’s registered identification number. It may also be known as an Ethernet hardware address (EHA), hardware address, adapter address, or physical address.

Small follow up of my former article on iproute2, in this article we’ll see some use of the command ss to know more information about Linux TCP / UDP Network and Socket Information

ss command is included in iproute2 package and is the substitute of the command netstat.

ss is used to dump socket statistics. It allows showing information similar to netstat. It can display more TCP and state informations than other tools.
