Description:

Install the NFS Kernel Server and allow mappings from the subnet 130.236.179.88/29

Implementation (Server-side):

  • Login as root
  • Install package nfs-kernel-server
  • Add the following line to /etc/hosts.allow:
portmap: 130.236.179.88/255.255.255.248
  • Add the following line to /etc/exports:
/usr/local         130.236.179.88/29(ro,root_squash,subtree_check)
  • Restart the services
service portmap restart
service nfs-kernel-server restart

Implementation (Client-side):

  • Login as root
  • Install package nfs-common
  • Attempt a mount:
mount -o ro,vers=3 -t nfs server.d4.sysinst.ida.liu.se:/usr/local /usr/local
  • If it works, add the following line to /etc/fstab:
server.d4.sysinst.ida.liu.se:/usr/local       /usr/local    nfs       ro,vers=3             0 0

Verification:

  1. Create file /usr/local/bin/hello which echoes hello.
  2. Run hello on client, should echo hello.
  3. Make sure it’s not possible to mount from other host
