Problem with false status

Alright,
Here is what I have changed if I read correctly:
1. In my hosts.cfg file I have the following entry (in bold is what was
changed):
# 'jello' host definition
define host{
use generic-host ; Name of host
template to use
host_name jelloxx
alias jelloxx
address 172.16.1.x
check_command check_host_alive
max_check_attempts 10
notification_interval 30
notification_period 24x7
notification_options d,u,r
2. In my checkcommands.cfg I have the following entries. Entry number
one was change back to it's original and entry number 2 was added.
These are both generic so if I decide to add more machines I will most
likely be ok.
# 'check-host-alive' command definition
define command{
command_name check-host-alive
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w
3000.0,80% -c 5000.0,100% -p 1
}
# 'check_ping' command definition
define command{
command_name check_ping
command_line $USER1$/check_ping -H $HOSTADDRESS$ -w
3000.0,80% -c 5000.0,100% -p 5
3. I installed fping from sunfreeware.com using pkgadd -d so that is
now installed on my machine.
Is there anything else that you can think of that I may need before I
restart nagios?
Thanks,
