Most Linux distributions, and most UNIX's, currently use the venerable arp, ifconfig and route commands. While these tools work, they show some unexpected behaviour under Linux 2.2 and up. For example, GRE tunnels are an integral part of routing these days, but require completely different tools iproute2 tutorial for ifconfig, arp, route users. October 6, 2012 by Pratik Sinha · 3 Comments. A lot of Linux distributions are shifting to iproute2 instead of net-tools (aka ifconfig, arp, route). The main reason being net-tools package hasn't been updated in a decade iproute2 is the Linux networking toolkit that replaced net-tools (ifconfig, vconfig, route, arp etc.). Most of the networking functionality is unified in the ip command. There's also tc for managing traffic policies (QoS), and ss (a netstat replacement), but this document is focused on the ip part

netem provides Network Emulation functionality for testing protocols by emulating the properties of wide area networks. The current version emulates variable delay, loss, duplication and re-ordering. If you run a current 2.6 distribution, (Fedora, OpenSuse, Gentoo, Debian, Mandriva, Ubuntu), then netem is already enabled in the kernel and a current version of iproute2 is included Pyroute2 is a pure Python netlink library. The core requires only Python stdlib, no 3rd party libraries. The library was started as an RTNL protocol implementation, so the name is pyroute2, but now it supports many netlink protocols.Some supported netlink families and protocols Iproute2 commands Iproute2 commands offer complete low-level network configuration capabilities. Here is a translation table from obsolete net-tools commands to new iproute2 etc. commands
Iproute2 carries its own sanitized version of the kernel headers so the current code will build and run on older kernel releases. It is recommended to always use the latest iproute2. Do not treat iproute2 like perf and require matching packages The command reference for the iproute2 tools provides sparse documentation of the NAT features, but has an appendix which covers the key questions with regard to iproute2 NAT. SuSe has Michael Hasenstein's paper on NAT, which is an excellent technical overview of the case for NAT The code includes kernel headers, standard C headers and an iproute2 specific header containing the definition of struct bpf_elf_map. iproute2 has a common BPF ELF loader and as such the definition of struct bpf_elf_map is the very same for XDP and tc typed programs . First, turn off the Network card using command: $ sudo ip link set dev enp0s3 down. Next, set the new MAC is using command: $ sudo ip link set dev enp0s3 address XX:XX:XX:XX:XX:XX.
