This configuration has been tested with nfs-utils-1.0.9-40.el5.

Make sure that nfs-utils is installed on dulak-server:

yum install nfs-utils

You need to modify the following configuration files on dulak-server (see Setting Up an NFS Server, and Configuring BOOTP/DHCP and NFS for a description of requirements for PXE/NFS kickstart installation):

• /etc/exports (specifies which/how volumes are shared):

  /dulak-server/home 10.3.0.0/255.255.255.0(rw)
  /scratch/isos 10.3.0.0/255.255.255.0(ro,async)

• /etc/hosts.allow (if the machine matches a rule listed here, then the machine is allowed access):

  ALL: LOCAL: ALLOW
  ALL: LOCALHOST: ALLOW
  ALL: localhost.localdomain: ALLOW
  # Secure Shell (SSH) connections:
  sshd: .fysik.dtu.dk: ALLOW
  #
  # Allow only rpc calls from the local subnet (eg. for NIS) & localhost
  # Warning: without the "ALL:" lines below https://bugzilla.redhat.com/show_bug.cgi?id=448006 happens, i.e.:
  # no DNS servers, can't look up hostname
  # ....
  # failed to mount nfs source
  ALL: 10.3.0.0/255.255.255.0
  ALL: 127.0.0.1/255.0.0.0
  portmap: 10.3.0.0/255.255.255.0
  portmap: 127.0.0.1/255.0.0.0
  rpc.mountd: 10.3.0.0/255.255.255.0
  rpc.mountd: 127.0.0.1/255.0.0.0
  rpc.rquotad: 10.3.0.0/255.255.255.0
  rpc.rquotad: 127.0.0.1/255.0.0.0
  rsync: 10.3.0.0/255.255.255.0
  rsync: 127.0.0.1/255.0.0.0
  in.tftpd: 10.3.0.0/255.255.255.0
  in.tftpd: 127.0.0.1/255.0.0.0
  snmpd: 127.0.0.1/255.0.0.0
  ucd-snmp: 127.0.0.1/255.0.0.0

• /etc/hosts.deny (if the machine does not match an entry in hosts.allow and matches an entry in hosts.deny then the machine is denied access):

  ALL: ALL

  Warning! If the machine matches no listings in hosts.allow nor hosts.deny files, then it is allowed access.

• start the nfs service:

  service nfs start
  service nfslock restart # (server mounts it's own dirs)
  service autofs stop &&  service autofs start # (server mounts it's own dirs)

• make these settings permanent (only after testing!):

  chkconfig --level 35 portmap on
  chkconfig --level 35 nfs on
  chkconfig --level 35 nfslock on

You are ready for installing Golden Client.

On both "dulak-server" and the "Golden Client" enable nfs mount:

• add to the /etc/auto.home file:

  dulak-server      -rsize=8192,wsize=8192,tcp      dulak-server:/dulak-server/home

• add to the /etc/auto.master file:

  /home   /etc/auto.home  --timeout=300

On the "Golden Client" only:

• enable nfs:

  service nfslock restart
  service autofs stop &&  service autofs start

• make this parmanent (only after testing!):

  chkconfig --level 35 portmap on
  chkconfig --level 35 nfslock on

Go back to installing software.
