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 Dmitri Pal 2012-04-24 16:17:00 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/2654

If DNS check for hostname<=>local IP address correspondence fail, unhandled exception is thrown from ipa-server-install.

Detail are inside Amazon EC2 bug:

#2648

https://bugzilla.redhat.com/show_bug.cgi?id=812692

Error message in exception is mysterious:
"No network interface matches the provided IP address and netmask"


It should say:
{{{
DNS check failed. Please check if forward records for your server name {hostname} point to IP addresses on this server. Please check reverse records also.

 Checked hostname: {hostname}
 Detected IP addresses: {ipAddrList}
 Forward records point to: {dnsIpAddrList}
 Reverse record {localIpAddr} points to name {dnsName}
}}}

More verbose is definitely better.

Code also should work if more IP addresses (and A/AAAA records) are detected.

Comment 1 Martin Kosek 2012-05-17 05:58:36 UTC

Fixed upstream:
master: https://fedorahosted.org/freeipa/changeset/eef056165f437e07c4a792d5545817a5517c59de

To test:

# echo "1.2.3.4 foo.example.com foo" >> /etc/hosts
# ipa-server-install --hostname foo.example.com

Installation will later fail with incomprehensible error message:

Unexpected error - see ipaserver-install.log for details:
 No network interface matches the provided IP address and netmask

The fixed server will report a better error message:

Invalid IP Address 1.2.3.4 for foo.example.com: No network interface matches the provided IP address and netmask
