Hi Hans,
Having looked at your previous post I assume that you did succeed in serving the AOLserver welcome page.
Why not start by changing the address in nsd.tcl to 127.0.0.1 until you get things going. It's also quite convenient to start AOLserver in the foreground: /home/aolserver/bin/nsd -ft /home/aolserver/nsd.tcl during this phase. Post relevant parts of the screen dump here so we can have a look (inside PRE tags please).
Did you read and follow the installation guide? What versions of everyting have you got?
