1. Make sure the 32bit libraries are installed (root# sudo apt-get install ia32-libs)
2. Use the synaptic tool to install nfs-common (root# sudo apt-get install nfs-common).
3. Use the synaptic tool to install nis (root# sudo apt-get install nis).

#During the configuration of nis, set the domain name to 
uncc.edu

1. Change the /etc/yp.conf file to have the entry (root# sudo vi /etc/yp.conf) :
2. (If you prefer other text edit tool like gvim, you can install it first (root# sudo apt-get install vim-gnome) then edit the configuration file (root# sudo gvim /etc/yp.conf))

#
# yp.conf       Configuration file for the ypbind process. You can define
#               NIS servers manually here if they can't be found by
#               broadcasting on the local net (which is the default).
#
#               See the manual page of ypbind for the syntax of this file.
#
# IMPORTANT:    For the "ypserver", use IP addresses, or make sure that
#               the host is in /etc/hosts. This file is only interpreted
#               once, and if DNS isn't reachable yet the ypserver cannot
#               be resolved and ypbind won't ever bind to the server.
# ypserver ypserver.network.com
ypserver visionserver-01.uncc.edu

1. Use the synaptic tool to install autofs (root# sudo apt-get install autofs).
2. Change the /etc/auto.master file to have the entry (root# sudo vi /etc/auto.master):

#
# $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#/misc  /etc/auto.misc --timeout=60
#/smb   /etc/auto.smb
#/misc  /etc/auto.misc
#/net   /etc/auto.net
/home   /etc/auto.home --timeout=60 --ghost

1. Create the /etc/auto.home file (root# sudo touch /etc/auto.home)
2. Change the /etc/auto.home file to have the entry (root# sudo vi /etc/auto.home):

#/etc/auto.home
*       -fstype=nfs4,sec=sys,rsize=8192,wsize=8192,soft,intr,nosuid,tcp         visionserver-01:/home1/&

1. Change the /etc/nsswitch.conf (root# sudo vi /etc/nsswitch.conf)

# /etc/nsswitch.conf
#
# Example configuration of GNU Name Service Switch functionality.
# If you have the `glibc-doc-reference' and `info' packages installed, try:
# `info libc "Name Service Switch"' for information about this file.

1. Edit the /etc/passwd file (root# sudo vi /etc/passwd)

# add this line to the end
+::::::

1. Edit the /etc/group file (root# sudo vi /etc/group)

# add this line to the end
+:::

1. Edit the /etc/shadow file (root# sudo vi /etc/shadow)

# add this line to the end
+::::::::

1. Edit the /etc/default/nfs-common file (root# sudo vi /etc/default/nfs-common)

# modify the lines having NEED_IDMAPD= to be the following
NEED_IDMAPD=yes

1. Edit the /etc/idmapd.cont file (root# sudo vi /etc/idmapd)

# replace the contents of the file to include the following
[Translation]
Method = nsswitch

[General]

Verbosity = 0
Pipefs-Directory = /run/rpc_pipefs
# set your own domain here, if id differs from FQDN minus hostname
# Domain = localdomain
Domain = uncc.edu

[Mapping]

Nobody-User = nobody
Nobody-Group = nogroup

1. Modify the rc.local script to restart nis if it is skipped in boot (root# sudo vi /etc/rc.local). This step may not be necessary for versions of Ubuntu >= 11.10.

#
# rc.local
#
# This script is executed at the end of each multiuser runlevel.
# Make sure that the script will "exit 0" on success or any other
# value on error.
#
# In order to enable or disable this script just change the execution
# bits.
#
# By default this script does nothing.
echo -n "Waiting for network to come up..."
while :; do
        nm-tool | egrep -q 'DNS:[[:space:]]+[1-9]' && break
        sleep 1
        echo -n "."

echo " OK"

/etc/init.d/ntp restart
/etc/init.d/ypbind restart
/etc/init.d/autofs restart
exit 0

1. Go to the root directory (root# cd /)
2. Rename the home directory to home.old (root# sudo mv home home.old)
3. Make a new home directory (root# sudo mkdir /home)
4. Make a new server directory for server applications (root# sudo mkdir /server)
5. Edit the file /etc/fstab to automatically mount the server directory on boot (root# sudo vi /etc/fstab)
6. Rebuild the yp file references (root# cd /var/yp; sudo make)

# add the following line to this file
visionserver-01:/server        /server  nfs4 rw,soft,intr,nosuid,sec=sys,tcp,rsize=8192,wsize=8192     0       1

1. Mount the /server directory over the network (root# sudo mount -a)
2. Install ntp (root# sudo apt-get install ntp)
3. Restart nis (root# sudo /etc/init.d/nis restart)
4. Restart autofs (root# sudo /etc/init.d/autofs restart)
5. Actually you might as well reboot the whole system (root# sudo reboot)
6. You may have to wait 30 secs to a minute for the network manager to come up and the script from rc.local to execute that will start the nis services.

1. The server /etc/exports file must be modified to include the new workstation.
