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 Kashyap Chamarthy 2011-11-10 16:46:15 UTC

Description of problem:

IPA needs a check to ensure host-names with 'underscore'  are not allowed as  it affects the host-* commands like trying to delete a host entry, etc.


Replica hostname:
==============
[root@x86_64e(107) ~] hostname
x86_64e.yzhang.redhat.com
[root@x86_64e(107) ~] 
==============

On master, attempt to delete the replica host entry:
==============
[root@x86_64c(105) ~] ipa host-del x86_64e.yzhang.redhat.com
ipa: ERROR: invalid 'hostname': may only include letters, numbers, and -
[root@x86_64c(105) ~] 
==============


Version-Release number of selected component (if applicable):
==============
[root@x86_64c(105) ~] rpm -qi ipa-server
Name        : ipa-server                   Relocations: (not relocatable)
Version     : 2.1.3                             Vendor: Red Hat, Inc.
Release     : 9.el6                         Build Date: Mon 07 Nov 2011 12:00:54 PM PST
Install Date: Tue 08 Nov 2011 01:14:02 PM PST      Build Host: x86-001.build.bos.redhat.com

Upstream ticket:

Comment 4 Jenny Severance 2012-01-11 18:37:05 UTC

FYI:  this is already automated ...

    rlPhaseStartTest "ipa-host-cli-53: Negative - add host with _"
        command="ipa host-add host_underscore.$RELM --force"
        expmsg="ipa: ERROR: invalid 'hostname': may only include letters, numbers, and -"
        rlRun "verifyErrorMsg \"$command\" \"$expmsg\"" 0 "Verify expected error message."
    rlPhaseEnd


It appears that it is not checked when installing a replica with "_" in the name.

Comment 5 Rob Crittenden 2012-03-01 19:37:54 UTC

Fixed upstream.

master: 61af2c9b1efe021fd6fac2c6c62160cde96ea3cb

ipa-2-2: ae8876e93c02c39c562bcdaa1396fcccaf1280c0

Host name validation should now be consistent.

Verified using ipa-server-2.2.0-12.el6.x86_64

# ipa-replica-prepare --ip-address 10.16.65.43 ipareplica_2.us.testrelm.com
Directory Manager (existing master) password: 

Invalid hostname 'ipareplica_2.us.testrelm.com', only letters, numbers, and - are allowed. DNS label may not start or end with -
