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.

Description Marko Myllynen 2011-08-29 07:38:49 UTC 
Description of problem:
ipa-client-install ... --hostname=foo.example.com breaks /etc/sysconfig/network like

NETWORKING=yes
HOSTNAME=localhost.localdomain
NETWORKWAIT=yes

during installation the end result being:

NETWORKING=yes
HOSTNAME=foo.example.comNETWORKWAIT=yes

It should also be noted that this happens before the confirmation prompt where the user is asked whether the installation should proceed so if the user simply hits Ctrl+C during the prompt the network configuration is invalid even if the installation was cancelled.

Version-Release number of selected component (if applicable):
IPA 2.1

Comment 3 Martin Kosek 2011-08-29 08:31:41 UTC 
Thanks for the report, I sent a patch for review upstream.

If you run ipa-client-install --uninstall after the installation cancelled with CTRL+C, network configuration will be correctly restored. But I have moved the actual changing of the network configuration in the patch after this prompt so that it is not this confusing.

Marko:  Does this sufficiently verify the issue you were seeing?
Comment 9 Marko Myllynen 2011-09-22 05:58:09 UTC 
> Does this sufficiently verify the issue you were seeing?

No, not really, there are two issues:

1) The test wasn't using --hostname so /etc/sysconfig/network wasn't modified at all by ipa-client-install (and that modification was broken earlier)

2) The client has hostname hp-dl380g6-01.testrelm but /etc/sysconfig/network has HOSTNAME=localhost.localdomain - what happens if the client's IP changes, will its hostname be changed then, too? I think ipa-client-install should have updated /etc/sysconfig/network also without --hostname.

I've added a comment about 2) to bug 714919 so it can be discussed there.

Thanks.

This is as expected since:
--hostname=HOSTNAME   The hostname of this server (FQDN). If specified, the
                      hostname will be set and the system configuration will
                      be updated to persist over reboot. By default a
                      nodename result from uname(2) is used.
