Free loss mitigation software for linux

Linux VacationLinux vacation is a automatic mail-answering program. This is my vacation port to Linux. It is derived from the vacation program found on agate.berkeley.edu in the 386bsd directory on Nov 16, 1993. The original program was written by Eric Allman in 1983 and is copyrighted by the Regents of the UCB. The copyright disclaimer is valid for this distribution as well, i.e. this version is provided `as is, and I shall not be liable for any damage, data loss or earthquakes in the bay area.

Version 1.1 was a security-patched version. The former version 1.0 had a bad security bug which Olaf Kirch reported to the CERT mailing list (after giving me a hint :-). Please DO NOT LONGER USE vacation-1.0!

As far as Copyrights are concerned, the original parts of vacation are under the BSD copyright whereas I place my changed under the GPL (see file COPYING in the directory).

I tried to make this port look just like the version found with SunOS 4.1.x. There are minor differences, it resembles more the Sun version than the original 386bsd source.

Unpack the package as follows

mkdir -p /usr/src # if not already present :-)
chdir /usr/src
gzip -dc /vacation-1.1.tgz | tar xpvf -

A simple `make install (install-aout is no longer supported as of version 1.2) should install binary in /usr/bin and the manpages in /usr/man/man*, respectively. If you choose different directories, edit the Makefile.

Weight Loss Recipe Book is a free, online, community-built recipe book. Weight Loss Recipe Book contains everything you need to allow your web site visitors to submit recipes and everything your administrator needs to administer the recipes.
When a visitor submits a recipe, the recipe is added to a database and awaits approval from the administrator before being added to the public site.
Main features:
- Community built, meaning you just have to approve entries and watch your web site expand!
- Captcha validation to prevent automated entries into the recipe book.
- Complete administrator system - add administrators, recipe categories, manage recipes and more!
- Best of all, Weight Loss Recipe Book is totally free!

StepStats is a smart and simple application that allows you to keep track of your sport successes. The application is perfectly suitable for all sports, where you want to create stats on distance, time or speed.
Main features:
- simple, understandable interface
- keeps track of date, distance, steps and time
- gives you stats with overall values and a nice graph with your speed
- automatic backup of your data once a week to prevent data loss or corruption
- available for MacOS X, Windows and Linux
- and best of all - It is Freeware

Ascension is my attempt at an email client. It makes use of the KDE libraries, so you will need KDE installed if you wish to use it (works with 3.2, might work with 3.1). Although the code is still in alpha, I have been using it as my main email client for over a year.
If you wish to try it, you would be sensible to backup your email first. Using imap should be relatively safe, but pop3 and Unix (local) mailboxes have not been so extensively tested. I take no responsibility for any loss of data while using this program. Ascension has only been tested under Linux.
The current version supports:
- IMAP (not SSL) mailboxes.
- Pop3 (not SSL) mailboxes.
- Unix mailboxes.
- Viewing of HTML messages (no HTML composing).
- Limited searching of headers.
- Dockable parts.
- Fonts and colours are configurable, as is much of the behvaiour.
Still to do:
- Support SSL connections (probably requires a rewrite of a good portion of the mailbox subsystem).
- PGP and S/MIME support.
- Virtual folders.
- A ton of ideas yet to come.
Enhancements:
- This is the first public release

Its main purpose, besides being fun to play, is to demo the specific versions of the server, archetypes and maps used by crossfire+. All files can be freely downloaded via CVS on the the crossfire+ project page.
It is especially suited for beginners who do not want to experience a very sharp and frustrating learning curve and party players who want to play together more easily.
Main features:
- Death is not permanent.
- Death causes no stats depletion and little experience points loss.
- Friendly fire causes no damage.
- Pet monsters and summoned creatures will not stand in the way of other party members, making it bearable to play with summoning skills in a party.
- The item power setting is "2".
- The crossfire maps can be viewed interactively at cfmaps.schmorp.de.
- We import your character file from other crossfire servers, up to some level, so you can use your character you played with at home, for example. Send your character files to crossfire@schmorp.de. Please dont send artifically improved characters.
- Player-killing is, as usual, not tolerated.
- If you want to try out a map on a public server, feel free to send it in.
- Map and graphics artists are working on improved graphics and new maps and quests.
- Due to the filthy ;) code quality, the server restarts automatically after a crash (within one minute).
- Emergency saves are disabled.
- You can reach the admins via IRC: server irc.schmorp.de (alternatively irc.plan9.de), channel #schmorp, user(s) schmorp or elmex.
- You can reach the admins via E-Mail: crossfire@schmorp.de.
- We are sometimes running the release, sometimes a CVS (not latest CVS) snapshot with some patches applied. If you encounter problems fixed in a newer snapshot feel free to report it.
- Player files and other variable data is backed up nightly to two different locations.
How to Connect
To connect to the server using e.g. cfclient or gcfclient, use this command:
cfclient -server crossfire.schmorp.de
or maybe...
cfclient -server crossfire.schmorp.de -mapsize 19x19 -font 9x15bold -cache
or you could use gcfclient or any other crossfire client.
If you use Debian GNU/Linux, you can find the clients in the crossfire-server-x11 and crossfire-server-gtk packages.
Enhancements:
- Large parts of the server have been rewritten.
- Map loading and saving and most I/O is done asynchronously, eliminating I/O-based lag.
- The server now regularly writes maps and players, so data loss on crash is minimized.
- Over 40 Perl extensions are available, such as a IRC gateway, transports, playershop, and minesweeper.
- The map system is now completely pluggable (for example, the world map is generated on the fly from an overlay).
- The file formats have been cleaned up and improved and use a faster parser now.
- A persistent database is available for data storage.

SmokePing is a delux latency measurement tool. SmokePing project can measure, store and display latency, latency distribution and packet loss. SmokePing uses RRDtool to maintain a longterm datastore and to draw pretty graphs, giving up to the minute information on the state of each network connection.
SmokePing uses latency measurement plugins for seamless extendability.
SmokePing comes with a smart alarm system. Apart from simple threshold alarms, you have the option of defining latency or loss patterns and use them to trigger alarms.
This allows you to define a pattern which would generate a single alarm when the loss goes from below 1% to over 20% and stays over 20% for more than 10 minutes. The advantage of this approach is the virtual elimination of duplicate alarms which you would get with a simple threshold based system.
Alarms can be sent to a mail address or a pager and if you want you can also start an external script to handle the alarms.
Complex Alarms can be written as plug-ins.
SmokePing can also deal with machines who frequently change their IP address by allowing the remote host to call SmokePings attention to its new IP address. In such a setup SmokePing monitors also for how long the remote system could keep its IP address.
To ensure that it is not suddenly monitoring the wrong host, SmokePing further tries to fingerprint each of its Dynamic IP targets via SNMP.
SmokePing is written in Perl. It consists of a daemon process responsible for data collection and a CGI script presenting the data on the web.
The CGI script uses SpeedyCGI to achieve mod_perl like performance without the need to deploy mod_perl on your web server. SmokePing sports a plug-in architecture to easily add new latency measurement capabilities to SmokePing. SmokePing works happily on all Unix platforms.
Enhancements:
- The scoreboard has a list of hottest targets.
- Echoping V6 compatibility.
- Mail templates.
- A failover server for alert email messages.
- Many new plugins.
- Several bugfixes.

Fast Data Transfer is an application for efficient data transfers that is capable of reading and writing at disk speed over wide area networks (with standard TCP).
It can be used to stream a large set of files across the network, so a large dataset composed of thousands of files can be sent or received at full speed, without the network transfer restarting between files.
The project is written in Java, runs an all major platforms, and is easy to use.
Main features:
- Streams a dataset (list of files) continuously, using a managed pool of buffers through one or more TCP sockets.
- Uses independent threads to read and write on each physical device
- Transfers data in parallel on multiple TCP streams, when necessary
- Uses appropriate-sized buffers for disk I/O and for the network
- Restores the files from buffers asynchronously
- Resumes a file transfer session without loss, when needed

Rocks provides an user-level package for reliable and mobile network connections.
Rocks protect sockets-based applications from network failures, particularly failures common to mobile computing, including:
.Link failures (e.g., unexpected modem disconnection);
.IP address changes (e.g., laptop movement, DHCP lease expiry);
.Extended periods of disconnection (e.g., laptop suspension).
Rock-enabled programs continue to run after any of these events; their broken connections recover automatically, without loss of in-flight data, when connectivity returns.
Rocks work transparently with most applications, including SSH clients, X-windows applications, and network service daemons.
Main features:
- Reliable: Rocks detect connection failures within seconds and reconnect automatically when connectivity is restored. Reconnection succeeds even when one end of the connection obtains a new IP address.
- Safe: Rocks recover lost in-flight data no matter when failures occur, safely interoperate with ordinary sockets, and authenticate resumed connections.
- User level: You can install and use rocks as an ordinary user. They do not require any kernel modifications.
- Transparent: You can use rocks with existing programs without re-programming, re-compiling, or re-linking.
- Easy to use: Rocks come with simple command-line tools for enabling rocks in ordinary programs.
Enhancements:
- Bug fixes.
