This is telling us that 'student's environment does not have access
to the file SYSKEY.TAB, or that the access (through a REDIRECTion)
is pointing at a file that is not readable or is zero length.  You
should logon as that student and do the following to determine what
is causing the problem:

<login as the 'student'>
cd mcidas/data
dmap.k SYSKEY.TAB

Does the file exist?  Is the REDIRECTion correct?  If the file exists,
is it readable?

I am betting that the REDIRECTion for SYSKEY.TAB in the 'student' account 
either does not exist, or is incorrect.  Correcting this should stop
the error messages from occurring.

I tried to both telnet and ssh to cyclone with no luck.  I would
guess that it is behind a firewall, and access to it has not been
allowed.  If you opened up waldo, I would most likely be able to
get to cyclone from it.  If you decide to do this, please give me
the password for the 'student' account.  Logging on as that user
is the only way to examine the problem.

OK.  ssh is _much_ better than allowing telnet.  The main reason for
this is that passwords typed in a telnet prompt go over the net
as plain text, so they can be easily seen and grabbed.  ssh, on
the other hand, encrypts everything, so passwords can't be sniffed.

One other thing.  I would strongly advise you to update passwords
for your 'ldm', 'mcidas', and 'root' users on waldo and other
machines.  The reason is that they may have been sniffed when I
used telnet.  If you decide to change these and you still want me
to logon, you should send me, not support, the passwords in a
message without identifying which passwords go with which account.
Alternatively, you could call me and tell me the passwords on the
phone.  I will be in my office all day until about 4:30.

>Let me know what you think.

I am more than willing to snoop around and correct any problems I
see if I can get access.

Tom
