2023-08-29check_smtp: Let port option always take precedenceFranz Schwartau1-1/+6
Otherwise -s/--ssl would overwrite a port given with -p if it comes after it, e. g. check_smtp -H mailhost.example.com -p 4465 --ssl Found-By: Lorenz Kästle

The port can still be set with -p.
2023-08-29Add support for SMTP over TLSFranz Schwartau1-9/+37
This is commonly used on smtps (465) port. PROXY protocol is not implemented with TLS in check_smtp.c, yet. Backported from nagios-plugins: https://github.com/nagios-plugins/nagios-plugins/commit/0a8cf08ebb0740aa55d6c60d3b79fcab282604fb

Add support for SSL/TLS hostname extension support (SNI) for check_smtp plugin. Backported from nagios-plugins: https://github.com/nagios-plugins/nagios-plugins/commit/9f1628f4b5525335ce1d6e48e8ac8b07d0757f82

This enables checks of SMTP servers that expect the haproxy PROXY protocol: -o smtpd_upstream_proxy_protocol=haproxy. Backported from nagios-plugins: https://github.com/nagios-plugins/nagios-plugins/commit/3246efe923b5482c5024c40e593ce942e628a3cb

2019-01-18Simply initializes n before it is usedrefs/pull/1574/headIustin Pop1-0/+1
When SSL is enabled, n is assigned the size of the server's second EHLO response (I think in bytes), which will usually be significantly higher than the command passed. As such, no commands are executed and no responses are checked, which - silently - defeats the desired checks and results in a success value.

2016-11-17check_radius: Replace functions removed in radcliHolger Weiss1-4/+0
The radcli library no longer offers the rc_get_ipaddr(), rc_good_ipaddr(), and rc_own_ipaddress() functions.
2016-11-13add openssl 1.1 supportrefs/pull/1443/headvagrant1-3/+5
changes: - CRYPTO_lock detection replaced in configure.ac. We don't use that function anywhere, so just replace it with the suggested one from https://wiki.openssl.org/index.php/Library_Initialization#Autoconf - OPENSSL_NO_SSL2 is no longer defined while ssl2 is not included. Set it ourself using the suggested openssl 1.1 version check from https://wiki.openssl.org/index.php/1.1_API_Changes#Backward_compatibility - openssl 1.1 sends a sigpipe if the connection is still open when calling SSL_shutdown(), so move the close before the shutdown.

2015-10-08check_smtp: extended support for expect optionrefs/pull/1382/headOliver Skibbe1-15/+22
expect option (-e) supported only first response, so checking for any other response like 250-xxx would never match. This fix stores return of relevant buffer closes #1381
2015-10-08check_smtp.c: modified SSL check for use with -erefs/pull/1379/headOliver Skibbe1-1/+1
- currently STARTTLS check does not work with -e if there's text like '220 hostname ESMTP*'. This is caused by SMTP answer from host. Postfix answer: 220 2.0.0 Ready to start TLS, Exchange 2010: 220 2.0.0 SMTP server ready. This fix checks against 220 closes #1093

2015-10-06check_smtp: QUIT SMTP connection when "-D" is usedHolger Weiss1-0/+2
Don't forget to issue an SMTP QUIT command when the -D/--certificate option is specified. This avoids undesired MTA log messages.

This is an initial take at renaming the project to Monitoring Plugins. It's not expected to be fully complete, and it is expected to break things (The perl module for instance). More testing will be required before this goes mainline.

2012-07-04Re-added missing variable declarations to check_smtp.cEric Stanley1-0/+2
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.
2012-06-29check_smtp: Remove a comment regarding MAIL FROMHolger Weiss1-15/+4
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.

2012-06-29check_smtp: Strip angle brackets from -f argument, if providedAnders Kaseorg1-1/+2
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.

2009-05-22Removed -n option in check_smtp's help and usage output (#2782784)Matthias Eble1-5/+1
Check_smtp's help showed the -n/--nocommand options to not send an SMTP command. This usage is covered by check_tcp and is thus not needed in check_smtp.
