We have a NAS server in the lab and I can reach it through the web interface at, and I have enabled NFS on the admin's panel.

enter image description here

After that I did

sudo aptitude install nfs-common
sudo mount -t nfs4 /media/thecus


mount.nfs4: Connection timed out

OS is Ubuntu 14.04. Any ideas?

  4. On the linux machine, sudo apt-get install nfs-common, sudo mkdir /media/thecus, then sudo mount -t nfs4 /media/thecus. You can get the WAN IP of the server on the front screen.
