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.
Previously, when a host name exceeded the 64-character limit, a warning message appeared but the configuration was still applied. Now, if the host name exceeds 64 characters, a warning message appears, and the host name is reset to localhost.localdomain. A host name can be successfully set if it is shorter than 64 characters.
Description of problem:
When set a long hostname and apply it, warning message will show in "applying configuration" box, it would be better if provide a separate warning box.
Version-Release number of selected component (if applicable):
rhev-hypervisor6-6.4-20121015.1.el6.
How reproducible:
100%
Steps to Reproduce:
1. Install RHEV-H.
2. Enter Network page, set a long hostname and apply it.
(e.g. localhost.localdomain111111111111222222222223333333333333334444444444444444444444444444444)
3. Focus on pop-up box.
Actual results:
1. The warning message"hostname: name too long" shows in "applying configuration" box, please see attachment for more details.
# hostname
localhost.localdomain11111111111122222222222
# cat /etc/sysconfig/network | grep HOSTNAME
HOSTNAME=localhost.localdomain111111111111222222222223333333333333334444444444444444444444444444444
2. After reboot, hostname will change to localhost.localdomain
# hostname
localhost.localdomain
# cat /etc/sysconfig/network | grep HOSTNAME
HOSTNAME=localhost.localdomain111111111111222222222223333333333333334444444444444444444444444444444
Expected results:
1. Provide a separate warning box when hostname too long
2. Or provide limit for hostname length.
