Nagios hosts showing as down

[Heylin, Alex]

You might find that the "port" entry for the check_tcp check is missing,
that has caused this here.  As you're using check_http it should be port 80,
being the HTTP port.
 
Hope that helps point you in the right direction.

Dear All, 

I have a strange problem with Nagios V1.1 using the plugins from v1.3.1. 

I have a remote router which ordinarily is checked by 'check_http' every x
minutes. In some cases the check fails (ADSL) so Nagios will then run the
host check command 'check_tcp'. However in some cases this fails and just
leaves the error message 'check_tcp: unknown argument (null). The majority
of the time though this check runs just fine. 

My questions is therefore, what am I doing wrong ? I have been running
Nagios for some time (great stuff Ethan) and this has only cropped up in the
last few months. If anybody has seen this, or can help I would appreciate it
greatly. 

Many thanks 

Matthew
