[Nagiosplug-help] check_ping: invalid hostname/address

[Michael Shoemaker]

# ping localhost
localhost is alive

# grep localhost /etc/hosts
127.0.0.1       localhost

resolv.conf contains the nameservers we use (all valid)

we are not using nis, but the hosts entry is below (just in case)
hosts:      files dns


# ./check_ping -H 127.0.0.1 -w 3000.0,80% -c 5000.0,100% -p 1
check_ping: Invalid hostname/address - 127.0.0.1
Usage:check_ping -H <host_address> -w <wrta>,<wpl>% -c <crta>,<cpl>%
  [-p packets] [-t timeout] [-4|-6]

I had checked the ip prior, I just forgot to include it in the notes.
