linux+yp /etc/nologin. How to exclude some users?

kyle292002bro · 12-11-2003, 07:03 PM

Guys,

I have linux box with yellow pages /etc/nsswitch.conf ....etc.
Everything works just fine.

Now, I would like to disable ALL logins except user PENGUIN

I put /etc/nologin, played with /etc/login.access, BUT no luck...

/etc/nologin - will disable ALL logins, BUT I would like to keep PENGUIN
(within yp of cource) off the list

Any input/ideas are welcome!

/etc/login.access:

-:ALL EXCEPT penguin:READ BELOW
"The third field should be a list of one or more tty names (for non-networked logins), host names, domain names (begin with "."), host addresses, internet network numbers (end with "."), ALL (always matches) or LOCAL (matches any string that does not contain a "." character). If you run NIS you can use @netgroupname in host or user patterns"

quoted from login.access manpage

Thanks!

Yes, I tried /etc/login.access...no luck.

I should use @netgroupname within YP, but I'm not sure about
the format within YP and /etc/nsswitch.conf (like passwd compat?)
