To mount a directory from a remote host, the host has to export that directory
via NFS. To do this, put the directorys name into `/etc/exports' on the
remote host. Then issue
showmount -e 127.0.0.1 to (re-)read
`/etc/exports' and actually export that filesystem. Also, this
command will show you all the directories you currently export.
Here's what FTP.UNI-REGENSBURG.DE's `/etc/exports' looks like to give DUSK (and everyone else) access to `/usr/aftp/pub/NetBSD-Amiga':
Again, there are a number of options to restrict access. Please refer to
export(5) for documentation.
