xfrm-policy-notifier

A small program that helps you monitor Linux XFRM policy changes. Only XFRM updates are monitored since IPSec daemon I use generates updates for link creations.

Howto

Packages required: libnl-3-dev libnl-xfrm-3-dev

Build project: mkdir build && cd build && cmake .. && make

Usage

Sample Ruby script:

require 'pty'

begin
PTY.spawn("./xfrm_policy_notifier") do |stdout, stdin, pid|
    begin
    stdout.each do |line|
        # do something on updates
    end
    rescue Errno::EIO
    end
end
rescue PTY::ChildExited
end
