mount a mounted filesystem

[Brian Stults <bs7452@csc.albany.edu>]

The unix system at my school is not mountable from off-campus.  However,
I can mount it via smbfs from my work computer (on campus), and I can
mount my work filesystem via nfs from home.  I figured that if the unix
filesystem is mounted to my work computer, I could access it from home
through my work computer.  However, when I mount the work filesystem and
access the directory under which the unix filesystem is mounted, it
appears empty.  If I ssh to my work computer and view the mounted
filesystem from there, it is not empty.  Is there some limitation here
that I'm not aware of, or some option that I must invoke?  I apologize
for the unclear explanation of the situation here.  I'm fairly new to
the language of remotely mounted filesystems.

Thanks.
