mount servername:/projects /mnt/nfs/projects
is hostname of remote system, /projects
is absolute path to directory on remote system, /mnt/nfs/projects
is absolute path to mount point (directory name) on local machine.
Note that the remote server must include an entry in /etc/exports to allow remote mounting of the /projects directory.
An anonomyzed example from my own machine (includes mount options from /etc/fstab)...
mount phobos:/exports/data/user /mnt/phobos
Or, with this line added to /etc/fstab:
phobos:/exports/data/user /mnt/phobos nfs noauto,tcp,soft
