RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
On a local machine, tcsh set the "REMOTEHOST" environment variable to an empty string, even though this variable should be only set on remote machines. This error has been fixed, and "REMOTEHOST" is no longer set on a local machine.
+++ 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.
The patch has been accepted by upstream (6.17.03b).
