From the sample config file for OpenACS
particularly this bit:
----------------
#
# If httpport is set to 80, you'll have to start AOLserver as root and pass the user
# AOLserver will run as in the command line. (e.g. ./nsd -u nsadmin -g nsadmin -t ../nsd.tcl)
# (assuming you're starting AOLserver from the {aolserverdir}/bin directory.
set httpport 80
set httpsport 443
#
# Make sure your /etc/hostname is setup right, with your full domain. If you want AOLserver
# to listen to www.foobar.com instead of foobar.com then hard code the appropriate domain
# in the line below (e.g. set hostname www.foobar.com).
#
set hostname [ns_info hostname]
set address [ns_info address]
#
# You can name your server whatever you want, but you'll need a directory with that
# name under {aolserverdir}/servers/ writable by you AOLserver user.
#
# For example: if your AOLserver is in /usr/local/aolserver and your server is "server1"
# you will need a /usr/local/aolserver/servers/server1 directory.
#
set server "server1"
set servername "openacs"
