Description Michael Gregg 2008-04-16 22:35:56 UTC 
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:
always

Steps to Reproduce:
1. add the hostname to the 127.0.0.1 line only, like:
127.0.0.1 <FQDN hostname> localhost
2. run ipa-server-install
3.
  
Actual results:
ipa-server-install exits with:
root        : ERROR    The IPA Server hostanme cannot resolve to localhost
(127.0.0.1), 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 127.0.0.1 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
127.0.0.1

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 23:45:41 UTC 
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 2008-04-17 00:39:41 UTC 
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 18:54:12 UTC 
Perhaps show what the /etc/hosts should look like.

===> ipa-server-install error: <===============
Server host name [replica64.ipaqa.com]: 

Unexpected error - see ipaserver-install.log for details:
 The IPA Server hostname cannot resolve to localhost (127.0.0.1). A routable IP
address must be used. Check /etc/hosts to see if replica64.ipaqa.com is an alias
for 127.0.0.1
