Thank you every body. I over looked in reading nis.howto, my apology. I think
I know how shoud I do with these Debian boxes, including ppc and old IPX/IPC
sparc.

Thank you

Don't put +::: in /etc/passwd, but list users individually:

+miquels:::
+chanop:::

Now only `miquels' and `chanop' exist on the box. You can even do:

+miquels:::
+chanop:::
+:*::

Now all users exist, but only `miquels' and `chanop' have a valid password
and can log in. Read /usr/doc/nis/nis.debian.howto.gz for more info.

One approach is to create a netgroup containing those users that are
allowed to log into the machine in question, and then making the NIS
entries in /etc/passwd

@netgroup::
+::/bin/false

where netgroup is the name of the netgroup containing the authorised
users and /bin/false is some shell which denies access (you might wish
to make it something that prints a message explaining what's happening).

When looking for a password entry, the system will take the first entry
that is matched, so users in the netgroup will be able to log in as
normal while everyone else will have their shell replaced by something
that logs them out again.

Read NIS-howto, for example you can create group and give them /bin/false as a 
login shell.

limiting NIS access

1999-09-07 Thread Chanop Silpa-Anan
Hi,

This is not Debian secific question. My system use NIS on all Sun machine. I
have a dew debian boxes running on the same network which use NIS from Sun
machine.

How could I limit an access to debian box to only some account. I still would
like to use NIS because of passsword maintenaince for user.

Is there a method in limiting NIS access. Now every user who has account on
Sun machine can log on to debian box with homedir=/ 

TIA
