2013-09-15check_tcp: use receive timeout for checks that expect responseSven Nierlein1-0/+14
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 stringHolger Weiss1-5/+7
Commit e8044713d41f5ef1d9ce814df4a079d8f92306b0 broke check_tcp checks without --expect string, this commit fixes that regression.
2013-09-12check_tcp: Properly deal will partial recv(3)sHolger Weiss1-11/+16
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() functionHolger Weiss1-14/+9
Replace the three boolean parameters of lib/utils_tcp.c's np_expect_match() function with a single "flags" parameter.
2013-09-10Fix GCC's -Wimplicit-function-declaration warningsHolger Weiss1-0/+2
Fix the issues found by GCC when the -Wimplicit-function-declaration flag is specified.
2013-09-10check_tcp: Don't close connection too earlyjuliopedreira1-4/+1
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 optionsSven Nierlein1-10/+15
"./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 -DHolger Weiss1-1/+1
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>).
