2018-10-22check_curl: implement certificate checksGravatar Sven Nierlein
Signed-off-by: Sven Nierlein <sven@nierlein.de>
2016-11-21sslutils: Address compiler warningGravatar Holger Weiss
SSLv23_client_method() and friends return a pointer to a const-qualified SSL_METHOD.
2016-11-07GMT expiry displayGravatar Peter (pir) Radcliffe
Change solution to display GMT time in the local display format with the offset number of hours from GMT to be clear about what timezone this is if the local display format does not include offset.
2016-11-07Use GMT timezone in SSL certsGravatar Peter (pir) Radcliffe
SSL certs are required to use times in GMT per https://www.ietf.org/rfc/rfc5280.txt but the mktime() here assumes the current timezone. Fix the time_t conversion to be done assuming GMT with timegm() and only do it once rather than twice. Display the expiry date and time with ISO format years and give an offset from GMT and a timezone to be very clear about exactly what time is being displayed. Time given is correct and now in the machine’s timezone.
2015-10-06Merge branch 'pr/1373'Gravatar Holger Weiss
* pr/1373: check_http: Allow for requesting TLSv1.1/TLSv1.2
2015-10-04check_http: Allow for requesting TLSv1.1/TLSv1.2Gravatar Holger Weiss
check_http's -S/--ssl option now allows for requesting the TLSv1.1 and TLSv1.2 protocols. Apart from that, a '+' suffix can be appended in oder to also accept newer protocols than the specified version. Closes #1338, and closes #1354, and closes #1359.
2015-10-02fix typo from #1336Gravatar Sven Nierlein
if exactly one hour before the expire date, we would mixup minutes and hours. Signed-off-by: Sven Nierlein <sven@nierlein.de>
2015-10-02Update sslutils.cGravatar Matthias Hähnel
Fixed Output if the expiration time is below one hour and code cleanup
2015-10-02Update sslutils.cGravatar Matthias Hähnel
optimize output if certificate expires in less then 24h thx to axel.schmalowsky@sixt.com for this patch
2014-07-21sslutils: expire time in local timezone formatGravatar Jan Wagner
sshutils prints the expiry time of certificates in US format this patch uses the strftime %c, I don't know how portable that is Thanks to Neil Prockter. Closes #1188 Closes #1161 Closes #977 Closes #976 Closes #975 Closes #840 Closes #382
2014-06-12Fix compilation with GnuTLSGravatar Holger Weiss
GnuTLS doesn't provide a SSL_CTX_check_private_key() function. Closes #1254.
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.
2013-09-10Don't mark SSL_METHOD variable as "const"Gravatar Holger Weiss
The SSL_CTX_new(3) function expects a non-"const" SSL_METHOD value.
2013-09-10Move global variables from .h to .c filesGravatar Holger Weiss
Simplify things by moving the definition of global variables into .c files, where they belong.
2013-08-20Set SSL_MODE_AUTO_RETRY flagGravatar Holger Weiss
We use OpenSSL (or GnuTLS) with blocking semantics, and we don't want SSL_read(3) or SSL_write(3) calls to return SSL_ERROR_WANT_READ or SSL_ERROR_WANT_WRITE (see #3614716).
2013-08-18Abbreviate function nameGravatar Holger Weiss
Make a very long function name at least a little bit shorter.

2012-06-11Fix whitespace and capitalization issuesGravatar Holger Weiss
Fix indentation and whitespace issues, and correct some capitalization errors in error messages. The behaviour is unchanged.
2012-06-11Don't use SSLv2 when compiling against GnuTLSGravatar Holger Weiss
GnuTLS doesn't support SSL version 2.
2012-06-06sslutils: Check if OpenSSL supports SSLv2.Gravatar Sebastian Harl
Recent versions/builds seem to disable that feature.
2012-05-28Add support for specifying SSL protocol versionGravatar Holger Weiss
The check_http -S/--ssl option now takes an optional argument which specifies the desired SSL/TLS protocol version (#3285367 - Jason Lunn).
2012-05-07Disable stateless SSL session resumptionGravatar Holger Weiss
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.
2011-02-04check_http: check for and print the certificate cnGravatar Thomas Guyot-Sionnest
This patch adds a check for the certificate cn (hostname) to normal certificate checks. It returns CRITICAL if th cn is missing, otherwise it prints it in the normal output. Patch by Stéphane Urbanovski
