Installing Samba and NFS server in BOSS and Setting NFS HOME in BOSS Linux

Step 1:

Install BOSS 64 bit version
Extract the Samba source kept under /opt
Open terminal and run below commands as admin user
                   cd /opt/samba-4.1.17
                   ./configure
                   make
                   make install
Step 2:

Once the Samba is installed successfully , we can provision the samba domain now.

Configure and Setup a Static IP for the machine. Eg: 192.168.1.10

Provide a Unique Hostname for the server. Eg: bossbigserver

Decide a Domain name that need to be given for the provision . Eg: rmdlab.lan

So the FQDN for the machine will be bossbigserver.rmdlab.lan

Add the Domain name as the default entry in /etc/resolv.conf .
Eg:
                   search rmdlab.lan
                   domain rmdlab.lan
                   nameserver 192.168.1.10

Once all these steps are done , open terminal and run below commands as admin user
                   cd /usr/local/samba
                   bin/samba-tool domain provision

Give rmdlab.lan as the domain name
For other values give the default answers
For Bind configuration provide the local ip I.e 192.168.1.10
Give a strong Admin password with all alphanumeric and punctuation combiantion

Once all the above values are given properly , the samba will be provisioned successfully.
Step 3:
Once done , run
                 sbin/samba
This should start Samba service , check it in
                sudo ps aux | grep samba
Step 4:

Adding users to Samba:

/usr/local/samba/bin/samba-tool user add

Give a strong password for the users with all the combinations.

To list all the users added to the domain , use
                  /usr/local/samba/bin/samba-tool user list

Setting NFS HOME:

Open terminal and run below commands as admin user
               mkdir /var/home
               chmod 777 /var/home

Open /etc/exports and add below entry

/var/home
(rw,sync,no_root_squash,no_subtree_check)

Run

exporfs -a

/etc/init.d/nfs-kernel-server restart

Now the Client machine can be authenticated from Server with Samba

username and passwrod

credntials and have the Home directory under /var/home in server.
