[Logcheck-devel] Bug#444097: /etc/logcheck/ignore.d.server/ddclient: 2 rules to get you started

[Frédéric Brière]

Package: logcheck
Version: 1.2.62
Severity: wishlist

Here are two rules for ddclient, a client for dynamic IP services such
as DynDNS or DynIP:

  ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ddclient\[[[:digit:]]+\]: SUCCESS:  updating [._[:alnum:]-]+: good: IP address set to [:[:xdigit:].]+$
  ^\w{3} [ :0-9]{11} [._[:alnum:]-]+ ddclient\[[[:digit:]]+\]: WARNING:  forcing update of [._[:alnum:]-]+ from [:[:xdigit:].]+ to [:[:xdigit:].]+; [[:digit:]]+ days since last update on \w{3} \w{3} [ :0-9]{16}\.$


Looking at the code, the first rule should match most (though not all)
services.  It's more or less impossible to say for sure, though -- who's
to say that all services return "good" upon success, for example.  All I
can say is that it works for me and my static DynDNS address.  (Let the
other users file their own bug reports.  <g>)

As for the second rule, despite being issued as a warning, it's
perfectly normal for static DynDNS hosts, and will appear once a month
if your address doesn't change.  (Basically, DynDNS prohibits updating
with the same IP over and over, but will allow such an update after 28
days, as their record expires after 35 days.  ddclient thus forces an
update after 30 days to be safe.)

BTW, I filed this report under the server level, as it is quite
conceivable to have a (small) server running behind a dynamic IP, for
example as a router.  (I myself am maintaining two such machines.)
