Odd check_http error

[Andrew Davis]

Oddly enough, low-level tests show an HTTP 302, which I expect. But 
Nagios is offering up a 400 error and a warning:

 From my workstation, confirming the server is configured correctly:

    gentoo:~ adavis$ telnet seth 8080

 From services.cfg:

    ## HTTP - alternate port
    define service {
            host_name                       seth
            service_description             HTTP
            check_command                   check_http!-p 8080!-u

            notes

            max_check_attempts              3
            normal_check_interval           15
            retry_check_interval            1
            check_period                    24x7
            notification_interval           120
            notification_period             24x7
            notification_options            w, u, c, r, f, s
            contact_groups                  unixadmins
            action_url                     
    /nagios/pnp/index.php?host=$HOSTNAME$&srv=$SERVICEDESC$
    }


And the result in Nagios:

    HTTP WARNING: HTTP/1.1 400 No Host matches server name seth
