Various improvements to network monitoring software, also a useful new feature for those running DHCP servers. Here are the details of the notable changes…

network

The schema for the LCFG network component on Ubuntu has gained a new per-interface resource – netmask6 – which can be used to specify the default netmask for IPv6 addresses. This is used when looking up IPv6 addresses from the specified hostname for the auto6 option. This is already supported in the component code.

On DICE develop systems we are testing moving the networkd-dispatcher.service from multi-user.target to network-online.target, the hope is that this will resolve some issues at shutdown time with services not stopping before the network routing has gone.

DHCP

The dhcpd component on Ubuntu now supports a new per-client address resource which may be used to reliably select the specific address which should be used when a hostname resolves to multiple addresses.

For those populating the DHCP server configuration using a spanning map, this requires schema changes for both the dhcpd and dhclient changes and they have to happen in the correct order so it will be a couple of weeks before it is possible to actively use this new option.

addrwatch

There is a new header – lcfg/options/addrwatch.h – which can be used to enable and configure the addrwatch service for monitoring the network and logging discovered ethernet/ip pairings.

arpwatch

The LCFG arpwatch component now supports Ubuntu. There is a new schema (version 2) which has been tweaked to give better support to the Debian/Ubuntu version of the arpwatch software.
