Hello ,
This is my 3rd Summary but I had a typo in the 2nd Summary.
I am sorry for the incovinience , please accept my apologies...

The original question was :
I want to run NIS (not NIS+) server on one machine
and I want to restrict login access to this machine.
All replied to me that the solution is to create a
netgroup whose members would have login access to this
#vi /var/yp/src/netgroup
add this line to netgroup file
netgroup_name_who_have_access (,member_1,) (,member_2,) ... (,member_n,)
#cd /var/yp/
#make netgroup
add at the end of /etc/shadow and /etc/group the line


add these lines at the /etc/passwd ( I missed it in my previous Summary )

change to

passwd : compat
group : compat

at /etc/nsswitch.conf

and of cource create /etc/no_login
The point is that I had done this stuff but nobody
could login in this machine.
Finally I did what I had to do from the beggining !!!
I changed the line
#EMULYP="-Y" to
at the file /etc/init.d/rpc and finally I got restricted login access
to this machine.
Thanks to those who replied

PS . Of cource there is a second way to Restrict login access
The only thing you have to do is edit /etc/nsswitch.conf
and change the lines

passwd : nis files
group : nis files


passwd : files
group : files

and add the people who should have access to this machine
localy , at /etc/passwd and /etc/group

but this I wanted to avoid...
