In fact, doing so can prove to be a security risk as you're inevitably giving up information about your network to a very public list. Since you didn't ask any questions, I'll just assume you sent that email without actually thinking through what it is you want. Since that's the case, I won't scold you for not reading the documentation before sending emails to this list either. However, it might well be that the most profitable hour you spend this year will be used to read all of the following document once: <a href="http://catb.org/%7Eesr/faqs/smart-questions.html" target="_blank">http://catb.org/~esr/faqs/smart-questions.html</a> Thank you for not wasting my time, or the time of other list participants. -- Andreas Ericsson <a href="mailto:andreas.ericsson@op5.se" target="_blank">andreas.ericsson@op5.se</a> OP5 AB <a href="http://www.op5.se" target="_blank">www.op5.se</a> Tel: +46 8-230225 Fax: +46 8-230231 </blockquote></div> Hi Andreas I have searched the Internet, and they have suggested to use check_http. sudo -u nagios /usr/nagios/libexec/check_http -I <a href="http://192.168.0.1">192.168.0.1</a> -u <a href="http://example.com/">http://example.com/</a> -p 7501 -w 10 -c 5 CRITICAL - Socket timeout after 10 seconds I get the above error.
