Free client software for linux

Ragnarok Online Client project is a client to the Ragnarok online network.
Ragnarok Online Client is a client to the Ragnarok online network, an MMORPG.
This project only provides an API to be able to program a client without having to understand the protocol itself, and to keep up-to-date just by the library.
Enhancements:
- Made it work with current iRO and improved it to be able to stay online until one kills it ... though no user interaction is implemented yet

PHP FTP Client is an FTP client that is useful for allowing people behind a firewall access to FTP without opening the FTP ports inside the firewall.
It could be used as a front end to a local FTP server, and therefore allow the administrator to provide access to the FTP server only from localhost.
Main features:
- Provide FTP access through a firewall which blocks FTP
- Provide a front end to an FTP server which only allows access to the web server, thus reducing the risk of the FTP server being attacked.
Enhancements:
- Have corrected problems with missing files. Was a case of linking against files I shouldnt have been.
- Added an FAQ, which currently only explains how to use the multi-file upload feature.

KABC Client is a command line tool that provides access to the KDE address book, which is also used by applications like KAddressBook.
It can take its input from either the command line or through standard input, allowing its use in Unix shell pipe and filter constructs. Input and output text is interpreted and formatted by filters.
kabcclient can perform the following operations:
- List: --list or -L
Write all contacts of the addressbook to stdout
- Search: --search or -S
Search for contacts matching the programs input
- Add: --add or -A
Add new contacts to the addressbook
- Remove: --remove or -R
Remove contacts matching the programs input from the addressbook
- Merge: --merge or -M
Add data from the programs input to matching contacts in the addressbook
Enhancements:
- Adding installation instructions and build files for creating Debian packages.
- No changes to the program itself!

HTTP Proxy Client is the small set of libraries and scripts, which provides transparent access to Internet via HTTP proxy for programs, which uses TCP/IP for communication.
The list of programs includes: telnet, ftp, licq, cvs, smth else? Project implements dynamic library, that can be preloaded before program run.
The library substitutes some system calls (connect(), gethostbyaddr(), gethostbyname()), with calls, which makes TCP/IP connection through HTTP proxy. This allows client programs behind HTTP proxy work with Internet without limitations.
At the moment tested on i386 Linux, i386/sparc Solaris.
Enhancements:
- While using dotted address, applications will attempt to connect regardless DNS lookup result.

Authorize.net AIM Client is a PHP client for the AIM API for Authorize.net.

Authorize.net customers can use this class to submit credit card charges to authorize.net. This is a PHP port of the Java class com.admc.lm.AIM.

Make sure to verify the checksums, and do not obtain these files from any other location if you dont trust the source or cant verify the download. I am not responsible if you get robbed by hacked versions of my code.

You may redistribute Authorize.net AIM Client according to the BSD open source license.

FlashUnity is a channel-based approach to an XML flash communications server and chat room.
Using the concept of channels and filters the FlashUnity server becomes extremely flexible and very easy to extend. Also, by using channels it is possible to run multiple modular functions within the same server.
Filters allow you to prefilter input for all channels or provide other functionality to all channels. This is a total rewrite of CyberSS, and the APIs and XML have multiple major changes. Each module, filter, and the chat client are in their own seperate PEAR package.
Enhancements:
- Room changes now work properly, and there are Uselist updates.
- This is the final release before 1.0.

Console Jabber Client is a Jabber client with text-based user interface resembling those known from popular IRC clients.

CJC is a Jabber/XMPP client for text terminals. Console Jabber Client uses pyxmpp library for XMPP comunication and curses for screen output. It is not finished yet, but still quite usable. Its user interface is resembling those of popular IRC clients like irssi or BitchX.

FSP Client is single executable client for the FSP protocol. Client uses an FTP-like user interface. People usually find this program easier to use that multiple client programs in FSP protocol suite. If you are at least somewhat familiar with command line FTP and want to try FSP, this program is a good choice for you.
There is a help command; not a very good one, but it does tell you the commands. Type `help to get a list of all commands; to get a brief description of a command, type `help name (`name being the command); to get brief help on all commands type `help all (warning: there are 46 commands).
See the manual page fsp(1) for a somewhat longer description...
Note for versions since 0.0-g: the command `cat, `get, `du, and `tar can all take a `-r flag -- this causes the commands to process subdirectories as well as files. e.g., `du will give the disk usage of the current directory; `du -r will give the disk usage of the current directory and _all_ subdirectories (resursively). The `timeout command causes communications to return an error code if the timeout occurs; this means that:
timeout 30
pro
iferror exit
is a good way of determining whether a remote site is alive or not when writing scripts. The `ver should only return an error if the timeout occurs -- however, pre-2.6.3 servers return version strings as an error which messes up that usage...
Macros are, for want of a better word, stupid. Until parameter variables are allowed, they can not do very much. Common ones (and user set up options) should be defined in the file ~/.fsprc (i.e., .fsprc in your home directory). This filename can be changed by setting the environment variable FSPRC. An example .fsprc is supplied in the file `fsprc in this directory.
It is also now possible to have commands like:
ls -l | less
Anything after the first `| symbol is fed the output of the builtin command...
rehash may need a little explanation -- when you do an ls, the directory information is fetched to the local end and stays there (thanks to the original authors stuff); if you want to check if anything has been updated since you did an ls of a directory, then you must rehash first. The client is now a bit more intelligent than it used to be (i.e., pre `d release); it will automatically mark directories as out-of-date if it knows that it has modified them (e.g., by put, or mkdir or whatever). Its the wrong command name, but it brings back fond memories of csh... It may sound like a disadvantage -- in fact it is an enormous benefit having it work this way... *much* faster.
All the commands which have a f equivalent in the original distribution behave as before; well, pretty much.
Oh, one last thing -- command lines cant have continuations... yet.

If you use it and like it, mail me. I need the encouragement If you use it and dont like it, mail me. I need bringing back down to earth...
Basically, even though it is pre-alpha, I would still like to know whether people like it or not... just dont complain too loud when it doesnt work right :-)
Enhancements:
- fsprc: wrack removed, decss added
- fixed statistics printing in stat command
- client/util.c add static prototype declaration
- avoid hammering of down sites
- fsprc: another FSP site added
