iproute2 to ip command – utilities for TCP/IP networking in Linux

it ip command The guide is a follow-up to my previous 90 Linux Commands Often Used by Linux Sysadmins article. Every week, or as time permits, I will publish articles on ~90 commands geared to Linux sysadmins and Linux power users. let’s continue this series IP Permission.

For Linux sysadmins, it is important to have a basic understanding of networking tools when managing and troubleshooting Linux servers. While we’ve covered some devices built primarily for monitoring, iproute2 and specifically IP The command is used to configure, view and modify network settings.

iproute2 is a Linux networking toolkit that has been replaced by net-tools (Including ifconfig And routeInstead of using a separate tool for every aspect of network management, with IProute2, sysadmins now have a unified interface.

Iproute2 has the following command-line utilities: arpd, bridge, ctstat, devlink, ip, lnstat, nstat, rdma, routef, routel, rtacct, rtmon, rtstat, ss, tc And tipc, Most networking functionality is integrated into ip Permission. there too tc for managing traffic policies (QoS), and ss who was replaced netstat,

ip command with example

ip The command is a part of the iproute2 package which is installed on all modern Linux distributions. This suite of networking commands allows system administrators to manage addresses, link-state, neighbor objects, routing tables, and other network components. ip The command also provides access to VRFs, network namespaces, policy-based routing, etc. It provides a similar syntax.

ip command example:

To list interfaces with detailed information, use:

ip address

To list interfaces with brief network layer information, use:

ip -brief address

To list interfaces with concise link layer information, use:

ip -brief link

To display the routing table, use:

ip route

To show neighbors (arp table), use:

ip neighbour

To move the interface up/down, use:

ip link set interface up/down

To add/remove an IP address in an interface, use:

ip addr add/del ip/mask dev interface

To add a default route, use:

ip route add default via ip dev interface

ip command and iproute2 useful read:

The iProute2 and IP commands are essential for Linux network management. We should know how to use commands to aid in network and system administration.
