This is the Scheme Untergrund Networking Package.
The Scheme Untergrund Networking Package (SUnet, for short) is a
collection of applications and libraries for Internet hacking in
Scheme. It contains over 15000 lines of high-quality Scheme code that
runs under Scsh, the Scheme shell. SUnet makes extensive use of
Scsh's facilities for multi-threaded systems programming on Unix.
SUnet includes the following components:
* The SUnet Web server
This is a highly configurable HTTP 1.0 server in Scheme.
The server is accompanied some libraries which may also
be used separately:
* URI and URL parsers and unparsers
* a library for writing CGI scripts in Scheme
* server extensions for interfacing to CGI scripts
* server extensions for uploading Scheme code
* simple structured HTML output library
The server also ships with a sophisticated interface for writing
server-side Web applications called "SUrflets".
* The SUnet ftp server
This is a complete anonymous ftp server in Scheme.
* ftp client library
This library allows you to access ftp servers programmatically.
* Netrc library
This library parses authentication information contained in ~/.netrc.
* SMTP client library
This library allows you to forge mail from the comfort of your own
Scheme process.
* POP3 client library
This library allows you to access your POP3 mailbox from inside Scsh.
* RFC822 header library
This library parses email-style headers.
* Daytime and Time protocol client libraries
These libraries lets you find out what time it is without paying for a
Rolex.
* DNS client library
This is a complete, multithreaded DNS library.
* An ls clone
This library displays Unix-style directory listings without running ls.
Download
========
The SUnet code is available from
http://www.scsh.net/sunet/
To run the code, you need version 0.6.4 or later of Scsh, available from
http://www.scsh.net/
Installation
============
Starting with version 2.1 SUnet conforms to the packaging proposal for
scsh by Michel Schinz and needs Michel's installation library to
install properly. For more information, please see:
<http://lamp.epfl.ch/~schinz/scsh_packages/>
In short, this means that you can install SUnet by unpacking the SUnet
tarball and issuing the following command in the created directory:
scsh-install-pkg --prefix /path/to/your/package/root
See the file INSTALL for the generic installation instructions for
scsh packages.
You need to install version 4.9 of the SSAX package to use SUnet. SSAX
is available from <http://lamp.epfl.ch/~schinz/scsh_packages/>.
Sample Web Server
=================
The installation procedure also installs three scripts to run the
SUnet httpd in the directory
/path/to/your/package/root/0.6/sunet/web-server/
The three scripts are:
start-web-server for running a simple web server on port 8080
start-extended-web-server for running a web server with rman and info gateway
start-surflet-server for running a web server with SUrflets enabled
Pass the --help option to learn how to configure the scripts.
These scripts should provide a pretty good starting point to set up
your own server or serve your own SUrfelts.
