Showmount, called on the client machine, shows the share:$ showmount 10.0.0.100 -eExport list for 10.0.0.100:/i-data/7fd943bf/nfs/zyxelNFS *The client's /etc/fstab contains the line:10.0.0.100:/i-data/7fd943bf/nfs/zyxelNFS /media/nasNFS nfs rw  0 0But mounting does not work:sudo mount /media/nasNFS/ -vmount.nfs: timeout set for Mon May 25 17:34:46 2015mount.nfs: trying text-based options 'vers=4,addr=10.0.0.100,clientaddr=10.0.0.2'mount.nfs: mount(2): Protocol not supportedmount.nfs: trying text-based options 'addr=10.0.0.100'mount.nfs: prog 100003, trying vers=3, prot=6mount.nfs: trying 10.0.0.100 prog 100003 vers 3 prot TCP port 2049mount.nfs: portmap query retrying: RPC: Program/version mismatchmount.nfs: prog 100003, trying vers=3, prot=17mount.nfs: trying 10.0.0.100 prog 100003 vers 3 prot UDP port 2049mount.nfs: portmap query failed: RPC: Program/version mismatchmount.nfs: Protocol not supportednfs-common is installed.
