Overview

Package netlink provides a simple library for netlink. Netlink is the interface a user-space program in linux uses to communicate with the kernel. It can be used to add and remove interfaces, set up ip addresses and routes, and confiugre ipsec. Netlink communication requires elevated privileges, so in most cases this code needs to be run as root. The low level primitives for netlink are contained in the nl subpackage. This package attempts to provide a high-level interface that is loosly modeled on the iproute2 cli.

Functions

func AddrAdd 

func AddrAdd(link Link, addr *Addr) error

AddrAdd will add an IP address to a link device.

Equivalent to: `ip addr add $addr dev $link`

If `addr` is an IPv4 address and the broadcast address is not given, it will be automatically computed based on the IP mask if /30 or larger.

func AddrDel 

func AddrDel(link Link, addr *Addr) error

AddrDel will delete an IP address from a link device.

Equivalent to: `ip addr del $addr dev $link`

If `addr` is an IPv4 address and the broadcast address is not given, it will be automatically computed based on the IP mask if /30 or larger.

func AddrReplace 

func AddrReplace(link Link, addr *Addr) error

AddrReplace will replace (or, if not present, add) an IP address on a link device.

Equivalent to: `ip addr replace $addr dev $link`

If `addr` is an IPv4 address and the broadcast address is not given, it will be automatically computed based on the IP mask if /30 or larger.

func AddrSubscribe 

func AddrSubscribe(ch chan<- AddrUpdate, done <-chan struct{}) error

AddrSubscribe takes a chan down which notifications will be sent when addresses change. Close the 'done' chan to stop subscription.
