Description Pavel Moravec 2014-12-08 12:27:22 UTC 
Title: Prerequisites

Describe the issue:
If (FQDN) hostname contains '_' character, katello-installer fails with "Failed to call refresh: /usr/sbin/foreman-rake db:seed returned 1 instead of one of [0]" error.

hostnames cant contain some characters (worth asking inecas for (dis)allowed chars) and Install Guide should reflect it in prerequisities - it prevents quite unrelated bug as above to appear.


Suggestions for improvement:
Before the point "Full forward and reverse DNS ..", provide list of (dis)allowed characters in server's hostname


Additional information:
Comment 4 Ivan Necas 2014-12-10 07:14:19 UTC 
The only allowed characters for a hostname are letters, numbers, dot (.) and dash (-).
Comment 5 Tomer Brisker 2015-01-11 07:54:41 UTC 
Similar validation is ready for testing on upstream for domain names.
Once merged it could also be used for validating host names.
Comment 6 RHEL Program Management 2015-04-21 16:07:58 UTC 
Since this issue was entered in Red Hat Bugzilla, the release flag has been
