I tried looking at my httpd.conf file but I am running Suse 9 and they split everything up into a bunch of different files. I could not find the file that changes the port of https from port 443 to port XXX. I also did a quick search on www.linuxquestions.org
and found nothing that popped out at me. I still have that tab open and will search there some more. You may want to post a question there.
