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.</FONT></SPAN></DIV>

hosts showing as down<BR><BR></FONT></DIV><BR><FONT face=sans-serif
size=2>Dear All,</FONT> <BR><BR><FONT face=sans-serif size=2>I have a strange
problem with Nagios V1.1 using the plugins from v1.3.1.</FONT> <BR><BR><FONT
face=sans-serif size=2>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.</FONT>
<BR><BR><FONT face=sans-serif size=2>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.</FONT> <BR><BR><FONT face=sans-serif
