Package: nagios-plugins-basic
Version: 1.5-2
Severity: normal

Dear Maintainer,

Today I updated the nagios-plugins* packages from version 1.5-1 to 1.5-2 on
our Icinga server.
After that, remote hosts being monitored by the check_ssh plugin were logging
error messages like the following:

         sshd[7315]: fatal: Read from socket failed: Connection reset by peer [preauth]

The rsyslog daemon on the monitored hosts is placing these messages in their
/var/log/auth.log files by default.

The Icinga server is checking these hosts around every 5 mins each, and they
all email these messages back to the system administrators via logcheck.

I downgraded the nagios-plugins* packages back to version 1.5-1 on the Icinga
server again and the messages ceased to occur on the monitored hosts.
