Missing lines for check_mk!

Undefined service??? It *IS* defined!

# /usr/sbin/inetd -d /etc/inetd.conf
ADD : check_mk proto=tcp, wait.max=0.40, user:group=root:(null) builtin=0 server=/usr/pkg/bin/check_mk_agent policy=
ADD : check_mk proto=udp, wait.max=0.40, user:group=root:(null) builtin=0 server=/usr/pkg/bin/check_mk_agent policy=
FREE: check_mk proto=udp, wait.max=0.40, user:group=root:(null) builtin=0 server=/usr/pkg/bin/check_mk_agent policy=
FREE: check_mk proto=tcp, wait.max=0.40, user:group=root:(null) builtin=0 server=/usr/pkg/bin/check_mk_agent policy=

Wow! It adds the service, then removes it again. It seems even the /etc/services entry checm_mk is found and matched!

>How-To-Repeat:
Install NetBSD latest releases or current
Install check_mk_agent into /usr/pkg/bin/check_mk_agent:
# cd /usr/pkg/bin
# cp <download-dir>/check_mk_agent.netbsd check_mk_agent
# chown root:wheel check_mk_agent
# chmod 0755 check_mk_agent
# rehash
# check_mk_agent
[...]

Configure check_mk service:
# echo "check_mk 6556/tcp" >> /etc/services
# echo "check_mk 6556/udp" >> /etc/services

Configure inetd:
# echo "check_mk stream tcp nowait root /usr/pkg/bin/check_mk_agent check_mk_agent" >> /etc/inetd.conf
# echo "check_mk stream udp nowait root /usr/pkg/bin/check_mk_agent check_mk_agent" >> /etc/inetd.conf

Configure rc.conf:
# echo "inetd=YES" >> /etc/rc.conf

(Re)Start inetd:
# service inetd restart

>Fix:
Matching /etc/services and service name given in /etc/inetd.conf seems not to work.
