Have you checked the nagios.cfg file and ensured the path for 
command_file is the same in both the nagios.cfg and nsca.cfg? Nagios 
should be creating the command file on start up.  If they are the same, 
check that nagios has write permissions to /var/lib/nagios3/rw.  Also, 
the command file is a pipe, not a simple file, so "touch" isn't good 
enough, you'll need to use mkfifo or mknod.
