2020-01-07check_tcp: add --sniGravatar Alexander A. Klimov
2016-11-13add openssl 1.1 supportGravatar vagrant
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.

2014-01-19Project rename initial commit.Gravatar Monitoring Plugins Development Team
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.
2013-09-15check_tcp: use receive timeout for checks that expect responseGravatar Sven Nierlein
if check_imap expects a string that never occurs, it currently waits forever because thats how the imap protocoll works. Use a receive timeout in that case so we can exit early with a proper error message.
2013-09-12check_tcp: Fix checks without --expect stringGravatar Holger Weiss
Commit e8044713d41f5ef1d9ce814df4a079d8f92306b0 broke check_tcp checks without --expect string, this commit fixes that regression.
2013-09-12check_tcp: Properly deal will partial recv(3)sGravatar Holger Weiss
The np_expect_match() function now returns one of three possible states instead of just TRUE or FALSE: - NP_MATCH_SUCCESS - NP_MATCH_FAILURE - NP_MATCH_RETRY The NP_MATCH_RETRY state indicates that matching might succeed if np_expect_match() is called with a longer input string. This allows check_tcp to decide whether it makes sense to wait for additional data from the server.
2013-09-12Improve interface of np_expect_match() functionGravatar Holger Weiss
Replace the three boolean parameters of lib/utils_tcp.c's np_expect_match() function with a single "flags" parameter.

Fix the issues found by GCC when the -Wimplicit-function-declaration flag is specified.
2013-09-10check_tcp: Don't close connection too earlyGravatar juliopedreira
Closing the connection because the bytes received are less than the buffer size assumes that all the bytes will be received in one go. This is not always true!
2013-02-10check_tcp: don't ignore trailing optionsGravatar Sven Nierlein
"./check_tcp -6 -p 80 host" leads to an error: TCP CRITICAL - Invalid hostname, address or socket: 127.0.0.1 because 127.0.0.1 is the fallback host, the tailing hostname was ignored.

2012-06-27check_tcp: Print performance data even with -DGravatar Holger Weiss
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 4d06603060fc1233861b164870f0d3a2e0d8d2eb. 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>).
