[Logcheck-devel] Bug#333233: ssh's own reverse DNS lookup failure messages are not ignored

[Elmar Hoffmann]

Package: logcheck-database
Version: 1.2.41
Severity: normal
Tags: patch

While violations.ignore.d/logcheck-ssh does filter out the warnings
about failed reverse DNS lookup from the TCP wrappers, it does not for
ssh's own messages (which are quite overly dramatic, too).
The attached patch fixes this.
