NAME

xttpd - Harmonic tide clock and tide predictor (web server)

SYNOPSIS

xttpd [port]

DESCRIPTION

XTide is a package that provides tide and current predictions in a wide variety of formats. Graphs, text listings, and calendars can be generated, or a tide clock can be provided on your desktop.

XTide can work with X-windows, plain text terminals, or the web. This is accomplished with three separate programs: the interactive interface (xtide), the non-interactive or command line interface (tide), and the web interface (xttpd).

xttpd is an XTide web server. It provides web-based access to XTide's tide predictions by allowing a web browser to speak directly to the XTide program in HTTP. xttpd can replace httpd or it can co-exist with one.

If you run xttpd with no command line arguments, it will assume that it is replacing httpd and try to bind port 80. If you want it to co-exist with an existing server, or if you do not have privilege to get port 80, give it the port number as the first command line argument:

You will then need to link it up as http://www.wherever.org:8080/ instead of just http://www.wherever.org/, but otherwise, no damage done. xttpd will try to set its UID to 'nobody' once the port is established, but will issue a warning and continue with the default user ID if this fails.

For a complete discussion of the command line options and a detailed explanation of the XTide package, please see the verbose documentation at http://www.universe.digex.net/~dave/xtide/.

CONFIGURATION

See the file /usr/doc/xtide/README.debian for an update to this section. You must set the environment variable HFILE_PATH to point to the harmonics files that should have been installed along with the xttpd program. Example:
