Passive Checks via NSCA -- Excedrin Headache Vat Numero Uno

Can you ensure that on your server, you have passive command logging
turned on, and then ensure that you're seeing your nsca commands coming in
over the network (ie, they show up in the log).  If you don't see them in
there, run a tcpdump or snoop or whatever, to ensure that you're really
receiving the nsca packets from the client.

You can also check to see if your passive services are accepting passive
updates by writing something into the named pipe command file.  For
instance, you could do this:

First, check to make sure your date command returns a time_t-style
timestamp (seconds since Jan1/70, 00:00:00) if you do this:

  date +%s

If not, you're on your own as for how to get a valid timestamp into this
command:

  echo "[`date +%s`] PROCESS_SERVICE_CHECK_RESULT;hostname;descr;return\
  code;plugin-output" >/location/of/your/nagios.cmd

That's all one line, not split...

If, on the local machine, you cannot get passive updates to update, it's
not an NSCA problem!
