Disabling RPC on a Sun U-60

[Nicholas Tang <ntang () nachtwache org>]

I was just asked a question, and I didn't know the answer, but I figured
someone on here must.

Our security admin has had repeated problems with disabling RPC on Sun
Ultra-60's running Solaris 2.6.  After disabling it, he says telnet and
some other tcp services start hanging.

Does anyone have any idea why?  The services are all running through inetd
and without TCP Wrappers (yet).  I don't recall ever seeing that before
but he says every U-60 he's used has done that.
