I’ve got an extant nagios setup using 3.0.b3 which is working fine but on a trial upgrade to 3.0.3 (different bo:evil: the check_http authentication is failing. I’ve snooped the difference down to the addition of a new header line but I can’t figure out why this causes a failure.
Command:
check_http -I localhost -u example.com -a user:Passwd
On 3.0.b3 the request sent is:
GET example.com HTTP/1.0
User-Agent: check_http/1.101 (nagios-plugins 1.4.7)
Authorization: Basic dXNlcjpwYXNzd2Q=
on 3.0.3 the request is:
GET example.com HTTP/1.0
User-Agent: check_http/v1991 (nagios-plugins 1.4.12)
Connection: close
Authorization: Basic dXNlcjpwYXNzd2Q=
Using telnet to resend the command from the box running 3.0.3 confirms that its the existence of the header line
Connection: close
that causes apache at the other end to always return 403 regardless of authentication credentials. Any one able to explain this behaviour to me - or better yet, give me a way to switch off the offending header?
