Hello Joe, Due to very strong naming conventions in our datacenter I am not free to name my hosts as I want. Also past experience showed us that appliactions need to be moved to other platforms and need to renamed then. Also it happened two times in the past three years that we had to move to a different datacenter host for economic reasons. For that situation we developed the approach to add an alias or better say cname record for the host or better say for the application in order to simplify host name changes.
The SSL certificates is a different story because we have to use the certs from a central CA in the organization. I could add the alias on the CA request but currently I have no idea how to import the CA and host keys. rhn-ssl-tool don't offer me to import key files from external CA as far as I know. The hostname is used in a plenty of other configuration files like jabber, cobbler etc. To have a complete list would be very helpful. regards Michael -----Ursprüngliche Nachricht----- Von: [email protected] [mailto:[email protected]] Im Auftrag von Joe Belliveau Gesendet: Mittwoch, 6.

However i would rename the host to the alias. Something that won't change often. Also why would you be renaming the host often ? Usually an update server is infrastructure and that should not move often. In the ssl build reply file just add all the aliases, like you would any other certificate request. How I do it is I name my hosts spacewalk-ma-01,02,03 etc. then alias them with a tag like cambridge , boston, worcester (Massachusetts cities indicating their locations) so that the datacenter guys can easily join them to the local repo. BTW mine are all proxy servers to the main. I think you need to consider just aliases in the ssl cert my friend. -Joe On Nov 6, 2013, at 8:02 AM, "FRANK Michael" <[email protected]> wrote: > Hello Michael, > > With alias I meant a cname record. > > regards > > Mike > > -----Ursprüngliche Nachricht----- > Von: [email protected] > [mailto:[email protected]] Im Auftrag von Michael Mraka > Gesendet: Mittwoch, 6.
