Getting a Web server running

Servers can be run on almost any UNIX workstation, Mac or PC that's connected to the network.
Servers usually are, but don't have to be run by the system administrator on a UNIX host. (so a user can run their own if they need to)
The source code and precompiled executables for many different servers are available at CERN httpd Document.
If you're a student at UCI, NACS offers free accounts on our "Electronic Access" systems which are running servers through a student run project called AntWeb.
Technical advice is available from NACS to departments and workgroups that want to put up their own web server.
NCSA HTTP server is available in NACS' DCSLIB software library for all supported platforms.
