Description Dmitri Pal 2012-04-24 12:17:00 EDT
This bug is created as a clone of upstream ticket:

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

Detail are inside Amazon EC2 bug:



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 01:58:36 EDT
Fixed upstream:
master: https://fedorahosted.org/freeipa/changeset/eef056165f437e07c4a792d5545817a5517c59de

To test:

# echo " 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 for foo.example.com: No network interface matches the provided IP address and netmask
