Package: denyhosts
Version: 2.6-10
Severity: normal
Dear Maintainer,
on one of my systems, denyhosts fails to start. Worse yet,
when starting the init script reports "ok" and nothing is
written either on the screen or on any log file.
But it does not really start, as can easily be verified by
means of 'ps' or by running:
# service denyhosts status
[FAIL] denyhosts is not running ... failed!
Running in foreground (denyhosts --foreground) I've got
the error:
Could not find environment variable: HOSTNAME
I've verified that indeed on my system that var is not
defined. Defining the variable solves the problem.
Here is a trivial patch to the init script which just does
that:
# diff -u denyhosts.orig denyhosts
--- denyhosts.orig 2011-08-17 10:21:17.000000000 +0200
+++ denyhosts 2013-12-11 15:52:07.740887778 +0100

CONFIG=/etc/denyhosts.conf
FLAGS="--purge --config=$CONFIG"
+export HOSTNAME="$(hostname)"
+
# Function that starts the daemon/service.
d_start() {
# Gracefully exit if the package has been removed.
P.S.: this seems to be related to similar bug reported on
other distributions:
https://bugs.launchpad.net/ubuntu/+source/denyhosts/+bug/87898

P.P.S.:
further investigation allowed me to track down the source of
the problem to this line that I had in the config file:
SMTP_SUBJECT = DenyHosts Report from $[HOSTNAME]
It used to work with previous version, and still does if
the HOSTNAME var is defined in the init script.
