[Logcheck-devel] Bug#400813: logcheck-database: allow - in hostnames in ssh refused connect messages

[Russ Allbery]

Package: logcheck-database
Version: 1.2.51
Severity: minor
Tags: patch

The format of the sshd "refused connect" log message when TCP wrappers is
used is "refused connect from <hostname> (<ip-address>)".  Since dashes
are allowed in hostnames, the line matching these entries should read:

^\w{3} [ :0-9]{11} [._[:alnum:]-]+ sshd\[[0-9]+\]: refused connect from [:[:aln
um:].-]+ \([:[:alnum:].]+\)$

(adding - to the first character class that matches the hostname).
Underscore may also be warranted, since although I believe it's a
technical violation of the DNS standards, I've seen sites that use
underscores.  I've only seen dashes in real logs, though.
