Hi Mai,

I got both emails, so I know the machine is up!

As you found out this was a Kerberos thing.

Can you tell us exactly what you did to disable Kerberos so that the
inquiry has complete information on how to get out of this problem?
Thanks!

Stay away from Kerberos? :-)

I just tested forward and reverse name lookup using these values:
forward works (name -> IP), but reverse does not (IP -> name).
This may be updated in time.

No.  Please disable telnet as soon as possible.  It is a big security
problem.

We will be loading software as time permits and I will be grabbing
the S-VISSR imagery to send along to SSEC.  I will keep you informed
about progress.

>Have a nice day, Mai

You too.

Cheers,

Tom
