Description Bryan Mason 2011-01-12 19:48:46 UTC 
+++ This bug was initially created as a clone of Bug #669171 +++

Description of problem:

    The $REMOTEHOST environment variable is set to an empty string
    when logging onto a local system in csh and tcsh.  It should be
    left undefined.

Version-Release number of selected component (if applicable):

    tcsh-6.17-8.el6

How reproducible:

    100%

Steps to Reproduce:

    1. Start tcsh or csh on a local console
    2. Run "echo $REMOTEHOST"
  
Actual results:

    $ echo $REMOTEHOST

    [note blank line]

Expected results:

    $echo $REMOTEHOST
    REMOTEHOST: Undefined variable.

Additional info:

    The expected results occur on a RHEL 5 system, but the actual
    results occur on RHEL 6 and Fedora Rawhide.  This could easily be
    considered a regression.
