NIS on Linux

Updating auto.master...

gmake[1]: Leaving directory '/var/yp/goofy.disney.com'

If anywhere in between the output, if there is a message like this

Make[1]:***No rule to make target /etc/shadow


Make[1]: Leaving directory /var/yp/goofy.disney.com

Then one of the files listed in the Makefile are missing.

To start NIS automatically at boot time, type the following at prompt:

[root@goofy /root]# /etc/rc.d/rc3.d

[root@goofy /root]# ln -s ../init.d/ypserv ypserv

This creates a symbolic link from the runlevel 3 startup directory. Now, we have a NIS master server running.

We now need a NIS client to work with. We can run the NIS client on the same machine running the NIS server

First of all, create the /etc/yp.conf file. This file has only two lines, which are as follows:

domain domainname

server nis_server

domainname is the name of our NIS domain and nis_server is the server's hostname.

Our file looked like this:

domain goofy.disney.com

server goofy.disney.com

The next file to edit is /etc/sysconfig/network file to set the NIS domainname at boot time which was discussed above.

The last file to edit is /etc/nsswitch.conf file.

# /etc/nsswitch.conf

# An example Name Service Switch config file. This file should

# be sorted with the

# most-used services at the beginning.

# The entry '[NOTFOUND=return]' means that the search for an

# entry should stop if the

# search in the previous entry turned

# up nothing. Note that if the search failed due to some other

# reason (like no NIS

# server responding) then the search

# continues with the next entry.

# Legal entries are:

# nisplus or nis+ Use NIS+ (NIS version 3)

# nis or yp Use NIS (NIS version 2), also called YP

# dns Use DNS (Domain Name Service)

# files Use the local files

# db Use the local database (.db) files

# compat Use NIS on compat mode

# [NOTFOUND=return] Stop searching if not found so far

# To use db, put the "db" in front of "files" for entries you

# want to be looked up

# first in the databases


# passwd: db files nisplus nis
