Fix the threshold specifications in the example for checking the number
of truechimers.

Mention that the check_ntp_peer plugin checks the stratum of the
synchronization peer, not the stratum of the monitored server itself.
Thanks to Marc Haber for bringing this up on the "nagios-users" mailing
list (Message-ID: <20120722142840.GA6931@torres.zugschlus.de>).
The "ssl_version" variable was undeclared when the plugins were compiled
--without-openssl and --without-gnutls.
Bug reported by Michael LaCorte on the "nagiosplug-help" mailing list
(Message-ID: <CCD30C91-A2A8-463A-82A9-F99B54F741D3@gmail.com>).
A recent update removed the declarations for a couple variables in
check_smtp.c that are still being used, which caused a failure
in the compilation of check_smtp.c. This commit restores those variable
declarations so the check_smtp.c will again compile.
Earlier versions of check_smtp generated an (invalid) "MAIL FROM"
command without arguments by default. These days, a "MAIL FROM" command
is only sent if the --from option is specified.
This commit removes a comment which explains the old behaviour, and it
updates a variable name accordingly.
Fixes many instances of
warning: ignoring return value of 'asprintf', declared with attribute warn_unused_result [-Wunused-result]

Apparently some people used -f '<nagios@example.com>' to work around
the bug I just fixed in the MAIL FROM: command generation. Although
the resulting command wasn't RFC-compliant, it was working with some
MTAs, so let's continue to support this syntax now that we generate
RFC-compliant commands.

Every version of the SMTP standard (from RFC 821 to the current RFC
5321) requires the address following MAIL FROM: to follow the colon
immediately (with no space) and to be surrounded by angle brackets.

When using the 1.4.15 release of the Nagios Plugins, a command such as
check_tcp -H pop.example.com -p 995 -D 14
usually produced two lines of output, e.g.:
OK - Certificate will expire on 12/13/2014 23:59.
TCP OK - 0.009 second response time on port 995|time=0.008849s;;;0.000000;10.000000
The second line was removed by 4d06603060.
However, as the old two-line output is a valid (though in this case
unintended) way to spit out performance data, removing the second line
might break current setups. Therefore, we revert to the old behaviour,
at least for the moment.
The issue was reported by Jochen Bern on the "nagiosplug-devel" mailing
list (Message-ID: <4FEAE812.8030309@LINworks.de>).
Don't return a WARNING state if the number of lost packets is greater
than zero but below the specified warning threshold. This happened
because the check_ping plugin used the exit status of the ping(1)
utility. (#3535140 - Tobias Brox)
In the C shell and in the Z shell, the "?" character must be quoted or
backslash-escaped in order to use it verbatim. Therefore, a command
such as
check_by_ssh -H test.example.com -l joe echo huh?
might fail, depending on joe's login shell on test.example.com.
Just to make sure, this commit removes most punctuation characters from
our test strings.
RFC 2131 (2.) says: "DHCP clarifies the interpretation of the 'siaddr'
field as the address of the server to use in the next step of the
client's bootstrap process." So, we shouldn't interpret this field as
the DHCP server's own address. (#3503921 - Jason Ellison)
Don't let "pad" options[*] terminate the parsing of DHCP options. This
bug was triggered by using check_dhcp against Windows 2003 DHCP servers
(see #3503921).
[*] Cf. RFC 2132, 3.1.
The ping6(1) implementation provided by Debian's iputils-ping package
may produce output such as the following:
| 3 packets transmitted, 0 received, +3 errors, 100% packet loss, time 2009ms
There's a corresponding pattern in check_ping.c:458:
| "%*d packets transmitted, %*d received, +%*d errors, %d%% packet loss"
Without this fix, the pattern in check_ping.c:456 matched first (as
sscanf(3) interprets "+3" as a match for "%d"):
| "%*d packets transmitted, %*d received, %d%% loss, time"
(#1894850 - Debian bug report #514588 - Matej Vela)
This metric compares the database engine server version with the specified
ranges. The version string [[[[A.]B.]C.]D.]E[.] is returned as E + D*100 +
C*10000 + B*1000000 + A*100000000 (see libdbi's dbi_conn_get_engine_version()
documentation).
