CentOS 4.7, Kerberos 1.3.4 Hi All: This is driving bonkers. A couple of weeks ago I started working on implementing Kerberos. I got as far as getting the primary/master KDC running on our CentOS development system before I got dragged off to work on something a little more pressing. I finally got back to it this week only to find that the krb5kdc service now fails to start. A check of the log files shows it has been working right up until the system was rebooted Sunday night. The reboot itself was not the problem as there had been previous reboots after which krb5kdc was able to restart. Here are the log entries for that latest retry: Jun 10 16:29:38 fisds0.forsoft.com krb5kdc[12490](info): setting up network...

The "unrecognized local address family 17" message were occurring even when it worked so I do not thing they are significant to this problem. As far as I am aware I have not made any changes to the system that should affect this. I have done a ton of Google searches but I have not turned up anything that seem to help. Any thoughts or suggestions would be greatly appreciated. TIA Regards, Hugh -- Hugh E Cruickshank, Forward Software, www.forward-software.com
