In that case I’ll go for

	% /usr/local/libexec/nagios/check_tcp -H 213.206.237.82 -p 655 -e 'lcrproxy'
	TCP OK - 0.035 second response time on 213.206.237.82 port 655 [0 lcrproxy 17]|time=0.035362s;;;0.000000;10.000000

which checks for the presence of the daemon, reachabililty of the host and whether it’s tinc that is running on port 655.
