WWWOFFLE - World Wide Web Offline Explorer - Version 2.7
========================================================
The WWWOFFLE programs simplify World Wide Web browsing from computers that use
intermittent (dial-up) connections to the internet.
Description
===========
The WWWOFFLE server is a proxy web server with special features for use with
dial-up internet links. This means that it is possible to browse web pages and
read them without having to remain connected.

- Allows the 'GET', 'HEAD', 'POST' and 'PUT' HTTP methods.
- Interactive or command line control of online/offline/autodial status.
- Highly configurable.
- Low maintenance, start/stop and online/offline status can be automated.
While Online
- Caching of pages that are viewed for later review.
- Conditional fetching to only get pages that have changed.

Changes
=======
Since version 2.6d:
Bug Fixes:
IPv6 getnameinfo() bug fixed. IPv6 freeaddrinfo() bug fixed. IPv6 ftp bug
fixed. Fix compile problem when not using zlib. Client acceptable compression
type detection fixed. Upgrade config script fixed (purge age). Remove gcc
warnings for xml.l and errors.c. Renamed UdmSearch to mnoGoSearch. Fixed bug

Check the wildcards in URL-SPECIFICATIONs in the configuration file are valid.
Distinguish between timeout and compression errors from the remote host.
Delete the Content-Length headers from URLs that wwwoffle has uncompressed.
Allow multi-line headers in requests. Don't request pages when monitor times
changed. Give warning on error writing to cache (disk full?). Don't remove the
If-Modified-Since header on non-cached requests. Fix iframe link finding error.
Reply to conditional requests when online as unchanged if unchanged on server.
Handle reserved HTML characters in FTP directory listings. Fix error finding
iframes when finding HTML links. Allow the compiled in localhost to be changed.

--------- Version 1.0 -----------
SmokePing is a Network Latency Monitor working along
the lines of MRTG. It measures network latency to a
configurable set of destinations on the net and
displays its findings in easy to read Web pages.
SmokePing has special support for monitoring
hosts with dynamic IP addressing.
SmokePing uses RRDtool as its logging and graphing back-end.
This makes the system very efficient. The presentation of
the data on the Web is done through a CGI which creates
graphs on demand.

Subject: The RULE project (Run Up2date Linux Everywhere)
Date: Mon, 11 Feb 2002 11:38:19 CST
Hello,
Following the discussions on the Red Hat Enigma list, I am happy to
announce the start of the RULE project:
Run Up2date Linux Everywhere
The first purpose of the project is to create a Red Hat Linux
installation option which requires less than 32 MB of RAM, optimized
to run server or basic SOHO applications on very limited hardware.
Even users of others distribution, however, can help and benefit of this
project (see FAQ number 5)
Target users are:
Everybody (particularly in developing countries) who can
afford only old computers unable to run the current Free
desktop environments and productivity applications.
System administrators and power users who don't need eye
candy, but pretend full functionality without being forced to
hardware upgrades just to keep doing the same things they
were doing before.
The temporary home page, which explains in more detail what we want to
do, why, how, and how you can help, is reachable at:
http://spazioweb.inwind.it/marco_web/
The project mailing list is already up and running.
Best Regards,
Marco Fioretti
RULE Project leader
