Nagios Support Forum

Hello
I am new to nagios. Trying to find out if this product fit to our infrastructure. And the very first test fail. Please advise

/usr/local/nagios/libexec/check_http -H 10.10.10.70 -S
CRITICAL - Cannot make SSL connection
3078281496:error:14077417:SSL routines:SSL23_GET_SERVER_HELLO:sslv3 alert illegal parameter:s23_clnt.c:674:
HTTP CRITICAL - Error on receive

Server receives only ssl3 connections. I think check_http plug-in tries to connect via ssl2 and ssl3 versions.

It seems like some HTTPS urls cause curl to fail with an "illegal parameter" error. Some claim that this error goes away if you manually specify "--sslv3". However, currently it is not possible to set a --sslv3 flag in check_http. You can check out these links for more info:

Sorry, I don't have a solution at this time. Try running "check_http" against a different server to see if it is going to fail.
