The /etc/services on your Iris should say:

	tcpmux		1/tcp		# TCP port multiplexer (RFC 1078)

Few Unix systems seem to implement it, though several non-Unix systems do.
(It's quite cute. See RFC 1078 for details, or say "man inetd" on the Iris.)

The rest of them are Sun/RPC program numbers, accessed through the portmapper,
not through fixed TCP/UDP port numbers ("services"). Look in /etc/rpc on the
Iris. Your YP server should have all of the non-SGI ones in any case. However,
so you won't have to go looking for them, the SGI ones you mention are:

	sgi_toolkitbus  391001
	sgi_fam         391002
	sgi_mountd      391004  mount showmount

(For other SGI-proprietary RPC program numbers see /etc/rpc on your Iris.)
