NFS Setup
=========

NFS Server Setup
----------------
1)  /etc/rc.d or /etc/init.d
    /usr/sbin/portmap or rpc.portmap

2)  /etc/exports

    /mn/riemann/local apollo(rw)
    
    (to make /riemann/local availabe to "apollo" with
    read and write.)
    
    /mn/riemann/local -rw=apollon
    (for IRIX, HP-UX, Digital-UNIX, SunOS 4, AIX)
        
3)  mountd      rpc.mountd
    nfsd        rpc.nfsd
    
4)  /usr/sbin/exportfs (and chomod a+rx)

    #!/bin/sh
    killall -HUP /usr/sbin/rpc.mountd
    killall -HUP /usr/sbin/rpc.nfsd
    echo re-exported file systems
    
    (Run script after modifying /etc/exports)
    
5)  rpcinfo -p (to check mountd and nfsd running)


NFS Client Setup
----------------                                                                           

1)  To mount,

    % mount -o rsize=1024,wsize=1024 riemann:/mn/riemann/local /mnt

2)  To unmount

    % umount /mnt

3)  To make the system mount a nfs file system upon boot

    /etc/fstab
  ______________________________________________________________________
  # device      mountpoint     fs-type     options              dump fsckorder
  riemann:/mn/riemann/local  /mnt    nfs        rsize=1024,wsize=1024 0    0
  ______________________________________________________________________

  After editing run the program shareall to export the filesystems.


Server security: the portmapper
-------------------------------

1)  First we edit /etc/hosts.deny.
  ______________________________
  portmap: ALL
  ______________________________

2)  /etc/hosts.allow.
  _____________________________________
  portmap: 193.123.123.0/255.255.255.0
