NIS/NYS security

Hi All,

after a bit of extra reading (Thanks to David Drury), I have NIS set up on 
my machines.  It uses the tcp_wrapper so to lock it down I need to modify 
/etc/hosts.allow and /etc/hosts.deny rather than /var/yp/securenets.  Can 
anyone let me know what the syntax for blocking these requests from a 
particular machine (or better yet, allow them from one machine only).  I 
have read the man pages for these files but can't find a satisfactory list 
of daemons I can choose from (I am going to shoot myself if is it as simple 
as ypserv : machine.i.want.to.block.com   or ypserv : 
machine.i.want.to.allow.com).

Cheers
Mark Collis
