Qstat is a command line based program that returns the status of internet Quake, QuakeWorld, and Quake 2 servers created by Steve Jankowski mailto:steve@activesw.com.
Here's the feature summary from the QStat homepage:
Qstat is a must-have tool if you're planning on doing any net play. A number of front-ends for qstat have been written as well. Some of them are listed later in this section.
You can get the latest version of qstat from the QStat Homepage ( http://www.activesw.com/people/steve/qstat.html.
XQF is a graphical front-end to QStat that uses the GTK toolkit. This is the best QuakeWorld/Quake2 server browser that currently exists, and Roman Pozlevich ( roma@botik.ru), is still cranking out revisions at the rate of about one per month.
If you're familiar with GameSpy for the Windows platform, this is the closest thing to it for Linux.
The XQF homepage is at http://www.linuxgames.com/xqf.
QuickSpy is a text-based QuakeWorld server browser. It's another front-end to QStat and it works pretty well. If you don't run X and you don't have Quake II, this is a decent option. Beware though, it's no longer under development.
You can get QuickSpy at http://diana.ecs.soton.ac.uk/~rht96r/quake/quickspy/.
Qplug is a Netscape plugin which retrieves and displays QuakeWorld and Quake II server information embedded in a web page. A Windows Qplug has been around for some time. The author, Olivier Debon ( odebon@club-internet.fr) wrote the Linux version from scratch without ever having seen the Windows version.
QPlug for Linux can be got at http://www.geocities.com/TimesSquare/Labyrinth/5084/qplug.html.
David Bucciarelli ( tech.hmw@plus.it), author of the 3Dfx driver for Mesa, has written a library called qkHack, which tries to emulate all the SVGAlib/fxMesa functions used by Quake and Quake II. This would remove the need for SVGAlib when running glquake or Quake II with ref_gl. Other features from the qkHacklib README:
I've tried qkHacklib and it works great for Quake on my system. In Quake II, however, the mouse response becomes really slow. Others report complete success, though, so give it a try it it sounds like something you need.
David Bucciarelli's qkHacklib web page is at http://www-hmw.caribel.pisa.it/fxmesa/fxqkhack.html.
GiMd2Viewer is a Quake 2 model viewer written for Gtk and OpenGL by Lionel Ulmer ( bbrox@mygale.org). It loads models and textures from either plain files or .PAK files. It will also animate the models (with frame interpolation).
This program is still under developement and I haven't tried it yet, but it sounds pretty nifty. Check it out at http://www.mygale.org/~bbrox/GiMd2Viewer/.
QIPX is a set of programs that allow Linux Quake clients (using TCP/IP) to connect with DOS Quake clients (using IPX). I guess this is useful if you're playing netquake on a LAN. QIPX is available at http://www.geocities.com/SiliconValley/Park/6083/qipx.html.
Ice is a Quake map editor for UN*X created by C.J. Beyer and John Watson. I haven't used this program, nor do I know what its development status is. The Ice homepage is at http://styx.phy.vanderbilt.edu/~ice/.
Q2getty is a hack of mingetty by Mike Gleason ( mgleason@ncftp.com) that allows you to automatically run and respawn a program (like a Quake server) on a virtual console. This program is available in the files section at //www.ncftpd.com/unixstuff/q2getty.html.
Rcon is a pair of tools that allow remote administration of a Quake II server using the RCON protocol. Michael Dwyer ( michael_dwyer@mwiworks.com) is the author. Rcon 1.1 is available at http://sunsite.unc.edu/pub/Linux/games/quake/rcon-1.1.tar.gz.
