Apache standalone server

I was able to successfully set up my linux box as a standalone web server for a program I use (for those familiar with crystallography, the program is CNS). However, I upgraded from Suse 6.3 to 7.0 and now when I try to access the CNS files using my machine as a web server, Netscape says it is unable to locate the server (my machine). I am including some information from some files and output from some commands to give a little more info. Any help would be appreciated. By the way, the program CNS requires perl in order for the web server function to work.
