+===NFS Configuration===
+----
+Required packages for cortana (NFS server):
+  * **nfs-kernel-server**
+  * **nfs-common**
+  * **portmap** (comes with nfs-common)
+Required packages for masterchief and arbiter (clients):
+  * **nfs-common**
+  * **portmap** (comes with nfs-common)
+After installing the **nfs-kernel-server** and **nfs-common** packages, **/etc/exports** is your best friend.
+The **/dev/exports** file:
+<file>
+# /etc/exports: the access control list for filesystems which may be exported
+#               to NFS clients. See exports(5).
+#
+# Example for NFSv2 and NFSv3:
+/srv       masterchief(rw,sync,no_subtree_check,no_root_squash) arbiter(rw,sync,no_subtree_check,no_root_squash)
+#
+# Example for NFSv4:
+# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check,no_root_squash)
+# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check,no_root_squash)
+#
+</file>
+**The uncommented line contains the client mount settings.**
+**fstab** has been configured to mount cortana:/home to the client's /home directory on startup.
+<file>
+# /etc/fstab: static file system information.
+#
+# <file system> <mount point>   <type>  <options>       <dump>  <pass>
+proc            /proc           proc    defaults        0       0
+devpts          /dev/pts        devpts  rw,noexec,nosuid,gid=5,mode=620 0  0
+/dev/xvda1 none swap sw 0 0
+/dev/xvda2 / ext3 noatime,nodiratime,errors=remount-ro 0 1
+cortana:/home /home             nfs     rw,sync,hard,intr       0       0
+</file>
+====NIS Configuration====
+----
+I followed a tutorial online to set up the NIS server and clients.
+Server configuration can be seen [[http://www.server-world.info/en/note?os=Debian_7.0&p=nis|here]].
+Client configuration can be seen [[http://www.server-world.info/en/note?os=Debian_7.0&p=nis&f=2|here]].
+===Server===
+The NIS domain is on the cortana server (srv-059).
+The first order of business is installing the **nis** package onto the server:
+<cli>
+apt-get install nis
+</cli>
+At the end of the installation, it will ask you to to choose the NIS "domainname" for the server, which I called **cortana** to keep the naming scheme for the project uniform. Next comes the file configuration:
+To go along with the tutorial and keep things simple and readable, I will only list the important changes in each file (all changes indicated with **change**):
+<file>
+root@cortana:~# vi /etc/default/nis
+# line 6: set NISSERVER to master
+NISSERVER=**master**
+root@cortana:~# vi /etc/ypserv.securenets
+# This line gives access to everybody
+.0.0.0 0.0.0.0
+root@cortana:~# vi /var/yp/Makefile
+# add shadow in front of passwd on line 119
+ALL = passwd **shadow** group hosts rpc services netid protocols netgrp
+root@cortana:~# vi /etc/hosts
+.0.0.1     localhost
+.0.1.1     cortana cortana
+# add the IP address for the NIS database
+**10.80.3.59    cortana**
+#update NIS database (press control-d when prompted)
+root@cortana:~# /usr/lib/yp/ypinit -m
+# start the NIS server
+root@cortana:~# /etc/init.d/nis start
+# When adding new users, you MUST UPDATE THE NIS DATABASE with the following method
+root@cortana:~# cd /var/yp
+root@cortana:~# make
+</file>
+===Client Configuration===
+Client configuration begins with the installation of the NIS package and asks for the NIS domain name, which will be **cortana**.
+Next, the real configuration:
+<file>
+root@client:~# vi /etc/yp.conf
+# At the end of the file, add the domain name followed by the server in the following format:
+cortana cortana.projects.lan
+root@client:~# vi /etc/nsswitch.conf
+passwd:         compat **nis**     # added on line 7
+group:          compat **nis**     # added
+shadow:         compat **nis**     # added
+hosts:          files dns **nis**  # added
+# Lastly, reboot the client.
+</file>
+With NFS and NIS configured correctly, you should now be able to log onto cortana from arbiter and masterchief as the users on cortana.
