NIS Master Server
# cat /etc/rc.conf
...
# Network Information System (NIS)
# NIS Master Server
nisdomainname="samdom.dominio.com"
nis_server_enable="YES"
nis_yppasswdd_enable="YES"
# A server that is also a client
nis_client_enable="YES" # run client stuff as well
nis_client_flags="-S samdom.dominio.com,alpha"
# mkdir /var/yp/samdom.dominio.com
# service ypserv start
# cp /etc/master.passwd /var/yp/master.passwd
# cd /var/yp
# edit /var/yp/master.passwd
Borro todos los usuarios especiales y solo dejo los que iniciaran en los equipos.
# chmod 0600 /var/yp/master.passwd
# ypinit -m samdom.dominio.com
Server Type: MASTER Domain: samdom.dominio.com
Creating an YP server will require that you answer a few questions.
Questions will all be asked at the beginning of the procedure.
Do you want this procedure to quit on non-fatal errors? [y/n: n]
Ok, please remember to go back and redo manually whatever fails.
If you don't, something might not work.
Can we destroy the existing /var/yp/samdom.dominio.com and its contents? [y/n: n] y
At this point, we have to construct a list of this domains YP servers.
alpha.samdom.dominio.com is already known as master server.
Please continue to add any slave servers, one per line. When you are
done with the list, type a <control D>.
master server : alpha.samdom.dominio.com
next host to add: ^D
The current list of NIS servers looks like this:
alpha.samdom.dominio.com
Is this correct? [y/n: y] y
[..output from map generation..]
NIS Map update completed.
alpha.samdom.dominio.com has been setup as an YP master server without any errors.

NIS Slave Server

# NIS Slave Server
nisdomainname="samdom.dominio.com"
nis_server_enable="YES"
nis_yppasswdd_enable="YES"
# A server that is also a client
nis_client_enable="YES" # run client stuff as well
nis_client_flags="-S samdom.dominio.com,alpha"
# mkdir /var/yp/samdom.dominio.com
# ypinit -s alpha samdom.dominio.com
Server Type: SLAVE Domain: samdom.dominio.com Master: alpha

Ok, please remember to go back and redo manually whatever fails.
If not, something might not work.
There will be no further questions. The remainder of the procedure
should take a few minutes, to copy the databases from alpha.
