After the 4.3 Update of the UCS Server I have this Nagios warning:
WARNING: HTTP WARNING: HTTP/1.0 400 Ungültige Anfrage - 655 bytes in 0.019 second response time
Can anyone help me to solve the problem?
Thanks a lot
Stefan
I’ve got these too. They are the results from the CUPS test. Cups and its web interface work, however.
Any ideas ?

Anybody out here who’s able to fix this ?

Hey,
this seems to be a bug in the CUPS NRPE check: CUPS doesn’t seem to support HTTP 1.0 anymore (which the check_http command uses by default). Adding -S 1.1 to the check_http command line in /usr/lib/nagios/plugins/check_univention_cups fixes the issue for me.
I’ve opened bug 46698 for this.
Kind regards,
mosu

Yes, thank you. Finally these nagging e-mails stop.
