unmatched entries for isc-dhcp-server

Thank you already for taking the time to report this bug and helping to make Ubuntu better.

It is really great that you identified and split up all these issues, but given that up to now neither Debian nor Ubuntu add tremendous functional delta to the upstream logwatch content I think the right way to address is to file them upstream (https://sourceforge.net/p/logwatch/bugs/).

Despite on sourceforge they seem to be still active there - Debian as well as Ubuntu can eventually pick it up on the next merge then.

If you are so kind and file them upstream it would be great if you drop us a note here or even link the upstream bug via "also affects project" above in Launchpad.

These appear to just be informational warnings about DHCP renewals, it sounds like they may be seen with some DHCP configurations, but are not necessarily an indication of an actual problem. Logwatch should probably just filter them.

The debian link (below) has the concise explanation of this warning:

>> What is this 'reuse-lease' all about?
>
> Your DHCP client renews the leased IP although the lease time is not
> expired. Not relevant to this problem.
>
>> Any suggestions, please?
>
> Clear your DHCP lease file on DHCP server. Bounce the thing by doing:
>
> $ systemctl stop isc-dhcp-server
> rm /var/lib/dhcpd/dhcpd.leases
> $ systemctl start isc-dhcp-server
>
> Make sure that the client is disconnected before doing the above.

The "Config file:", etc. lines are filtered by this in the dhcpd service script:

      ($line =~ /^[^ ]* file: /)

That was added by commit 42c445dd dated 2018-10-02

The reuse_lease messages are still uncaught, so will need a filter added.

This bug was fixed in the package logwatch - 7.5.4-0ubuntu2
