// Package rtnetlink allows the kernel's routing tables to be read and altered.
|
|
// Network routes, IP addresses, Link parameters, Neighbor setups, Queueing disciplines,
|
|
// Traffic classes and Packet classifiers may all be controlled.
|
|
// It is based on netlink messages.
|
|
//
|
|
// A convenient, high-level API wrapper is available using package rtnl:
|
|
// https://godoc.org/github.com/jsimonetti/rtnetlink/rtnl.
|
|
//
|
|
// The base rtnetlink library xplicitly only exposes a limited low-level API to rtnetlink.
|
|
// It is not the intention (nor wish) to create an iproute2 replacement.
|
|
//
|
|
// When in doubt about your message structure it can always be useful to look at the
|
|
// message send by iproute2 using 'strace -f -esendmsg' or similar.
|
|
//
|
|
// Another (and possibly even more flexible) way would be using 'nlmon' and wireshark.
|
|
// nlmod is a special kernel module which allows you to capture all (not just rtnetlink)
|
|
// netlink traffic inside the kernel. Be aware that this might be overwhelming on a system
|
|
// with a lot of netlink traffic.
|
|
//
|
|
// # modprobe nlmon
|
|
// # ip link add type nlmon
|
|
// # ip link set nlmon0 up
|
|
//
|
|
// At this point use wireshark or tcpdump on the nlmon0 interface to view all netlink traffic.
|
|
//
|
|
// Have a look at the examples for common uses of rtnetlink.
