$ sudo apt-get install nano
$ sudo mkdir /media/folder_to_share
$ sudo chown -R your_user:your_user /media/folder_to_share
$ sudo chmod -R 755 /media/folder_to_share
$ mkdir ~/folder_to_share

$ sudo apt-get install nfs-kernel-server
$ sudo cp -a /etc/exports /etc/exports_original
$ sudo nano /etc/exports

# /etc/exports: the access control list for filesystems which may be exported
#               to NFS clients.  See exports(5).
#
# Example for NFSv2 and NFSv3:
# /srv/homes       hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_subtree_check)
#
# Example for NFSv4:
# /srv/nfs4        gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check)
# /srv/nfs4/homes  gss/krb5i(rw,sync,no_subtree_check)
#
# Export /home/user/folder_to_share and /media/folder_to_share to IP adresses 192.168.1.0/24 and 192.168.1.10 :
/home/user/folder_to_share   192.168.1.0/24(rw,async,insecure,no_subtree_check,nohide)
/media/folder_to_share   192.168.1.10(rw,async,insecure,no_subtree_check,nohide)
