Host checks not executed?

Hi!
I'm using Nagios-1.1 from Suse-9.0. I configured some of my hosts like this:
define host{
use generic-host
host_name web
alias WEB
address 12.34.56.78
check_command check-host-alive
max_check_attempts 10
notification_interval 480
notification_period 24x7
notification_options d,u,r
}
but in the web interface in section "Host Detail", the column "Last Check"
only shows the date/time of the last `/etc/init.d/nagios reload`. In
addition, "Status information" says "(Host assumed to be up)" as if the
check_command had been commented out.
I indeed configured 2 hosts without a check_command, but also the others
are only "assumed to be up".
What could have went wrong? I do not understand how often host checks are
being executed, as there are only max_check_attempts for the check_command
defineable for each host. Service checks do work. Any hints?
FYI:
# nagios -v /etc/nagios/nagios.cfg | egrep ^Warning
Warning: Host 'gateway' has no services associated with it!
Warning: Contact 'daemon' is not a member of any contact groups!
i.e. I didn't configure 'gateway' to be pinged as "Service" additionally -
I only want to know if it is up/down to block service checks for hosts
beyond. Is that OK like this?
TIA & Regards
