announcing services

[Andrew Hume]

i am trying to announce a service on a sun 3 running sunos 4.0.
i did what i did on the mips, namely add the line
fmclient	729/tcp
to /etc/services, and the line
fmclient	stream	tcp	nowait	andrew	/usr/v9/lib/filemotel/doclient	doclient
to /etc/inetd.conf, and then kill -1 pid(inetd).
on the mips this worked. according to the documentation,
i think it should work on the sun. but it doesn't.
dmesg yields the diagnostic:
Apr 15 18:23:01 shamash inetd[173]: fmclient/tcp: unknown service

this error persists across a reboot. I have no idea why it doesn't
work. does anyone out there have a guess?
and if not a guess, how can i find out more (debugging)?
