Description Michael Gregg 2008-04-16 18:35:56 EDT
Description of problem:
when the hosts file is mis configured, ipa-server-install fails.

Version-Release number of selected component (if applicable):
RHEL IPA nightly build from 4-15-08

How reproducible:

Steps to Reproduce:
1. add the hostname to the line only, like: <FQDN hostname> localhost
2. run ipa-server-install
Actual results:
ipa-server-install exits with:
root        : ERROR    The IPA Server hostanme cannot resolve to localhost
(, a routable IP address must be used.

Expected results:
IPA-server install can exit. I expect the installer to detect this problem and
explain that in it's failure message.
Something like:
IPA server install detected that the machines hostname resolves to the
most common cause of this is a misconfigured hosts file. Make sure the hostname
is referenced only to the real IP of the machine in the hosts file, and not to

Additional info:
This hosts file configuration type is the most common configuration that RHEL
sets up. We need to detect it.
Comment 1 Rob Crittenden 2008-04-16 19:45:41 EDT
So the bug here is that the error message is bad, not that we don't handle the
case of a misconfigured /etc/hosts, right?
Comment 2 Michael Gregg 2008-04-16 20:39:41 EDT
Right, I didn't state that very clearly.

The bug is that we don't explain this very well to the end user. 

IPA not installing properly with a mis-configured hosts file seems fine. 

Comment 3 Rob Crittenden 2008-04-30 14:54:12 EDT
Perhaps show what the /etc/hosts should look like.

Unexpected error - see ipaserver-install.log for details:
 The IPA Server hostname cannot resolve to localhost ( A routable IP
address must be used. Check /etc/hosts to see if replica64.ipaqa.com is an alias
