Make sure that your "command_file" declaration in nsca.cfg
is pointing to the same "external command file" that Icinga
uses and that the processes are running with proper permission
to write to that file. You also might want to set the
"alternate_dump_file" declaration to another file that can
be written into if the main command file is unavailable for
any reason (including permissions); that can be useful for
troubleshooting.

You must have the hosts/services that are being run actively
on the "satellite" defined in the "central" instance. Look into
the "active_checks_enabled" and "passive_checks_enabled" in the
object configuration doco; you will find hints in there. The basic
premise in a distributed setup is to have the services on the
aggregator host (your "central" system) only accept passive
checks (active_checks_enabled 0) for things that are actively
checked on the monitoring hosts (your "satellite" host). Note that
you will probably want to look into "freshness checking" once you
get the basics working, but worry about the basics first.
Cheers!
