Httpv2 check issue with "body-string" and checking for a minus "-"

[KoMa666]

CMK version: 2.3.0p6
OS version: Debian 12

The following check is not possible: check_mk_active-httpv2!–url http://$HOSTADDRESS$/crl.pem --body-string ‘-----END X509 CRL-----’

Trying this check on the command line show that the “-” (Minus) cant be used in “body-string”, not with single quotes and also not with double quotes:

OMD[XXXsiteXXX]:~/lib/nagios/plugins$ /omd/sites/XXXsiteXXX/lib/nagios/plugins/check_httpv2 --url “http://XXXipaddressXXX/crl.pem” --body-string ‘-----END X509 CRL-----’
error: unexpected argument ‘-----END X509 CRL-----’ found

As soon as I remove the “-----” and only check for ‘END X509 CRL’ it works fine.

not sure I understand are you placing a certificate on a webserver so anyone can download it? what do you want to do with the cert in checkmk?

Hi,

I think you need to escape the minus sings since there are interpreted as additional arguments.
This should work:

./check_httpv2 --url http://XXXipaddressXXX/crl.pem](http://xxxipaddressxxx/crl.pem) --body-string “-----END X509 CRL-----”

Hi @T.Schmitz, @Anders,

not really, I tried with single and double quotes and also with escaping on single “-” (Minus).

Please see the screenshot, I hope it explains what I mean:

As soon as you want to check for something that includes a “-” (Minus) it won’t work.
I tested today with 2.3.0p11 with the same behavior.

if you run curl and grep for your data is its found I guess? just to rule that out

[KoMa666]

Yes the data is fine. As you can see in the output, the minus causes a failure in the check as it is interpreted as an option/argument even it is in quotes.

[Anders]

Ok,
just a question, why do you need the whole ----- part? Would’t “END X509 CRL” work?

[KoMa666]

Hi @Anders,

sure. This works.
But nevertheless there is a misbehaviour in the check that you can’t check for “minus” characters.
