We are pleased to release SUnet version 2.0.
The Scheme Untergrund Networking Package (SUnet, for short) is a
collection of applications and libraries for Internet hacking in
Scheme. It contains over 9000 lines of high-quality Scheme code which
runs under Scsh, the Scheme shell. SUnet which makes extensive use of
Scsh's facilities for multi-threaded systems programming und 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 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.
While SUnet 2.0 is a direct descendant of Olin Shivers's original SUnet
package, we have overhauled almost every single API in the system, and
added many new components. Thefore, it would be useless to list the
details of all the changes---if you have code relying on the SUnet 1.0
API, you'll almost certainly have to change it. We provide extensive
documentation to help you with that task. Moreover, we have tried to
produce robust APIs and thus hope that future releases will be able to
preserve them as much as possible.
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/
Please direct questions, comments, answers about SUnet to the regular
scsh mailing list at
scsh@zurich.ai.mit.edu
