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)
Some versions of OpenSSL fail to negotiate the SSL connection with at
least some versions of Tomcat if stateless SSL session resumption
support (see RFC4507) is enabled:
| CRITICAL - Cannot make SSL connection
| 140099330348712:error:140943F2:SSL routines:SSL3_READ_BYTES:sslv3 alert unexpected message:s3_pkt.c:1195:SSL alert number 10
The problem is reproducible with OpenSSL 1.0.0h, but not with OpenSSL
0.9.8o-4squeeze12 (as shipped with Debian 6.0.4). We work around it by
disabling the RFC4507 functionality when using OpenSSL versions which
support it.
Thanks to Dag Bakke for reporting the issue and for giving me access to
a server I could use to reproduce the problem.
Add a note to the --help output which clarifies that check_http doesn't
perform certificate verification (beyond what the "-C" option does).
(Suggested by Michael Renner in Debian bug report #644627, forwarded by
Jan Wagner.)
Fix the code which accepts a comma-separated list of labels specified
via the "-l" option.
