[389-users] Changed hostname of machine. FDS Admin Server FAILS to start: Could not reliably determine the server's fully qualified domain name

Hello everybody and thanks for the continued support. It's incredible. I thought I'd be clever and installed my FDS on a machine with a hostname of localhost.localdomain When I rename it to it's proper hostname, a.b.c, the admin server FAILS when I start it: ./dirsrv-admin start Starting dirsrv-admin: httpd.worker: apr_sockaddr_info_get() failed for a.b.c httpd.worker: Could not reliably determine the server's fully qualified domain name, using 127.0.0.1 for ServerName [FAILED] Honestly, I've tried everything I can think of, for example: - hacking /etc/init.d/dirsrv-admin - hacking /etc/dirsrv/admin-serv/httpd.conf specifically the variable: ServerName a.b.c:390 - hacking /usr/sbin/start-ds-admin ... Q1. Can anyone recommend a solution ? Thanks, Dave
