Conguring a master NIS server: Follow the following steps
to set up a server on the second
physical machine:
1. Set up the NIS domain name with the domainname command.
Use groupi.cs498hou.uiuc.edu
as the NIS domain name for the ith group.
1
domainname groupi.cs498hou.uiuc.edu
2. Determine what les you would like to share via NIS by
editing /var/yp/Makele. Search
for the following block of lines in the makele
GROUP = $(YPPWDDIR)/group
PASSWD = $(YPPWDDIR)/passwd
etc ...
This tells NIS where your database les are located (note
that $(YPPWDDIR) is set
to /etc at the top of the makele). You need to edit the
block of lines properly. Scroll
down the makele until the following block is reached:
all: passwd group hosts rpc services netid protocols mail \
# netgrp shadow publickey networks ethers bootparams printcap \
# amd.home auto.master auto.home auto.local passwd.adjunct \
# timezone locale netmasks
This line species which maps will be made available via
NIS. You need to edit this
block of lines in order to specify which les you would like
to distribute. The only les
you need to distribute for your network are ypservers,
passwd, group, hosts, rpc, services,
netid, and protocols.
3. Initialize the NIS database with
/usr/lib/yp/ypinit -m
Do not add any slave server, as our network is really small
and a master server is
sucient. (The hosts that you add are put to the le
/var/yp/ypservers.)
4. To start the NIS server automatically at boot time, use
the commands /sbin/chkcong
--------------------------------------
Conguring an NIS client: As compared to conguring an NIS
server, NIS clients are much
easier to set up. You need to modify the following three les.
1. Edit the le /etc/yp.conf, e.g., for the rst group,
the le should be like
# /etc/yp.conf - ypbind configuration file
# Valid entries are
#
domain group1.cs498hou.uiuc.edu server m2.cs498hou.uiuc.edu
# Use server HOSTNAME for the domain NISDOMAIN.
#
#domain NISDOMAIN broadcast
# Use broadcast on the local net for domain NISDOMAIN
#
#ypserver HOSTNAME
# Use server HOSTNAME for the local domain. The
# IP-address of server must be listed in /etc/hosts.
#
2. Edit the /etc/syscong/network le to set the NIS domain
name at boot time.
NISDOMAIN=group1.cs498hou.uiuc.edu
3. Edit the /etc/nsswitch.conf le. Search for the block of
lines
passwd: files nisplus nis
shadow: files nisplus nis
group: files nisplus nis
hosts: files nisplus nis dns
services: nisplus [NOTFOUND=return] files
etc...
The order placed in the le determines the search order used
by the system, e.g., the host-
names are rst searched for in the /etc/hosts les, then via
NIS in the map hosts.byname,
and nally by DNS via the DNS server specied in
/etc/resolv.conf.
4. Now all the les are in place, set up the client daemon
to automatically start at boot time
by creating a symbolic link from /etc/rc.d/rc.3/S60ypbind to
/etc/rc.d/init.d/ypbind.
