  I was hoping someone else would respond to your question since I can't claim
to have the first-hand knowledge necessary to answer it (I don't do a lot of
work with Suns), but I've seen the topic discussed at least a couple times
before, so I think I might be able to help.

In article <2379@bnlux0.bnl.gov>, abrams@.dan.adm.bnl.gov (The Ancient Programmer) writes:

  OK, you're missing the shared libraries.  This is the problem I've seen
discussed in the past.  One way to solve it is to compile an ls binary that is
statically linked.  Another way is to do what you did....

  I seem to recall that /dev/zero is Sun's version of /dev/null.  If you
create ~ftp/dev and create a "zero" device in it with the same major and minor
device numbers as the /dev/zero in your root filesystem, this problem should
go away.

  Well, this is simply because there's no ls binary for ftp to run, so it
can't print a listing.

  Hope this helps.
