You can add, delete, replace or flush entries in the ARP table using this command. Ip neighbor command provides options to work with ARP table. Linux networking commands, part 1.3: ip neighbor You might get the error вЂњRTNETLINK answers: Device or resource busyвЂќ when trying to change the features of a interface, trying the command after making interface вЂњdown will work To make an interface up (or down) in linux, use You can configure interface parameters like MAC, MTU, status etc using вЂњip linkвЂќ Linux networking commands, part 1.2 : ip link Sudo ip -6 addr add fc00::1/64 dev wlp3s0 You can use the option вЂњ-6вЂќ with the above command to configure or delete IPv6 address. If multiple ip addresses are configured, you can delete all address using вЂњflushвЂќ Note: вЂњipвЂќ command allows configuring multiple ip address in one interface. To delete ip address replace the option вЂњaddвЂќ with вЂњdelвЂќ in the above command вЂњip addrвЂќ can be used to add, delete, replace and show IP address of an interface. Linux networking commands, part 1.1 : ip addr вЂњip -bri aвЂќ will show both IPv4 and IPv6 addresses, If you want to filter only IPv4 addresses use

If you need more detailed information about interfaces like MAC address, MTU size, broadcast address etc, use (You can also use the command in abbreviated form as вЂњip -bri addrвЂќ or just вЂњip -bri aвЂќ )ДЇor those who like a fancy output, use вЂњ-cвЂќ option to get the output in color This command can also be used for monitoring the status of interfaces, routes, addresses continuously.Д¬hecking IP address and status of all interfaces вЂњipвЂќ can be used for configuring interfaces, multicast address, arp table, routes, NAT, packet encryption, tunneling, routing policies etc. вЂњipвЂќ command is the SwissKnife for networking included in the iproute2 package.

IPROUTE2 TUTORIAL HOW TO

This tutorial describes how to use вЂњipвЂќ command for configuring IP address, MAC address, routing table, ARP table etc. Networking commands which are part of of the iproute2 package are ip, tc, arpd, ss, bridge, devlink, rtmon, nstat, routef, routel, ctstat and lnstat. Iproute2 package contain commands for linux kernalвЂ™s advanced networking features like tunneling, traffic controlling, packet encryption along with commands for doing familiar tasks like configuration of interfaces (IP addresses, MAC addresses, MTU, Link status etc), routing table, multicast addressing, arp table etc. Though popular, most of the linux distributions are slowly trying replace these with the networking commands present in new package iproute2. These commands are part of the package net-tools which has been part of all linux distributions for a long time. You would have probably used commands like ifconfig, route, arp, hostname etc if you have done networking with linux devices. Linux networking commands are provided by two packages iproute2 and net-tools. Checking ARP table using 'ip neighbor' command.Please repeat the above test to check that the commands are working. With the following command, we can launch a container including all of the above tools: docker container run -it cmd.cat/netstat/ip/nslookup sh

We can then install the tools required for troubleshooting: apk add -update-cache iproute2 bind-tools net-toolsДЄt this point, the troubleshooting can begin!Дocker Captain Lukas Lach has published a special registry called cmd.cat which installs tools based on the name of the image. The following container uses the same network namespace as the broken instance of nginx: docker container run -it -network container:broken alpine When two processes share a network namespace, they will behave identically on a network level. Run separate container for troubleshooting вЂ¦ check for basic troubleshooting tools: netstat Inside the container, several tools for troubleshooting networking issues are missing.ДЄfter entering the containerвЂ¦ docker container exec -it broken sh Launch the вЂњbrokenвЂќ containerДЇor the sake of this tutorial, letвЂ™s assume that we are troubleshooting an instance of nginx called broken: docker container run -d -name broken nginx This approach keeps containers clean from tools required for troubleshooting. We will launch a new container sharing the same network namespace. In this tutorial we will learn how to troubleshoot networking issues without changing a running container.
