ZDaemon

ZDaemon is a modified Doom source port based on ZDoom for both Windows and Linux/Unix (server only at this time), purposely-built for playing multiplayer games over the Internet. The current official version is. ZDaemon itself is based on ZDoom 1.23, which was one of the last major versions of ZDoom before moving to its current 2.xx codebase. It features some of the features available from ZDoom such as the majority of line types, sloped lines, and deep water, but it lacks some of the more advanced functions of later versions of ZDoom, such as an uncapped framerate, advanced ACS scripting support, DECORATE, flat and texture mixing, and other similar features. However, ZDaemon itself features an enhanced network code suitable for client/server games, stats and experience collection, teamplay support, and a Capture the Flag mode.



Supported Games

 * Doom and Doom shareware
 * Doom II
 * The Ultimate Doom
 * Final Doom
 * FreeDoom
 * Heretic
 * Hacx

Hexen is only partially supported by the ZDaemon engine because it is based on the old ZDoom base code, version 1.23. Support is to be added but the priority is very low.

Game adaptations
The voices used for announcements of most CTF/Deathmatch/Team Deathmatch games were taken from Quake III Arena and Unreal Tournament. They were compiled together by the creator of the WADs zvox.wad and zvox2.wad, and are subject to change with time. There are also some custom soundpacks which are made and maintained by individual authors and are subject to change at any time according to the author.

The ZDaemon community
The ZDaemon community itself, while not part of the ZDaemon program in a strict sense, plays a huge role in experience of playing ZDaemon online. It features many methods of discussion, many ways to 'get involved', and the ZDaemon team themselves would host many things that normally would get relegated to other outside organizations or websites.

The community's discussion and gaming services include:


 * The ZDaemon Forums.
 * ZDaemon Chat / #zdplayers on ZDirc.
 * #zdaemon on irc.freenode.net.
 * ZDaemon Tournaments.
 * ZDReview.

Weekly Gaming Sessions
ZDaemon has scheduled gaming sessions each week, such as "Wednesday Night Flags," which is a weekly Capture The Flag game, "Thursday Night Survival," which is a weekly cooperative game where each player has a limited number of lives during each round, "Friday's Monster Mash" which is a weekly cooperative game where players have an unlimited number of lives/respawns, "ZDaemon Sessions," which is where the staff and/or community chooses a wad/map to play each Saturday, and finally, "Frag Your Brains Out," which is a weekly free-for-all, or deathmatch, that is run every Sunday.

Other utilities
ZLauncher

ZLauncher is a specialized launcher made specifically for ZDaemon. It provides an official list of currently available servers for people to play on. It also features a buddy list, GetWAD (automatic wad downloading), a quick link to ZSW (the server wizard) from the menu, a WAD file setup utility, demo recording, playback utilities, a built in chat lobby (based on IRC), and embedded forum access. It is maintained by team member Kilgore.

ZDaemon Server Wizard

This is a new utility for creating a ZDaemon server.

ZDaemon Relay Chat

This is a modular IRC client created by team member Kilgore which was designed for use with the ZDaemon IRC chat server. It can still act as a general purpose IRC client. When used within ZLauncher, it automatically joins ZDaemon's IRC server, enabling users to chat other players who are logged in to ZDaemon. zrc.exe is a standalone version of the client which can also be used to access ZDaemon's IRC server, however the user must provide their master server account password on the connect line as the IRC server's password in order to connect.

GetWAD

This is a modular utility created by team member Kilgore that looks on various repositories for user created mods (wad, pk3 files, for example) which it then downloads and extracts to the user's specified directory automatically.

Linux and Mac support
ZDaemon provides server binary builds for Linux and FreeBSD. During the 1.09 beta phase a Mac client was available for testing. An official Linux and Mac client release is planned for 1.10 or later. Until the arrival of a native client, users may play using emulation software such as WINE, Cedega or CrossOver. Playing using this software is allowed.

History
2001

On January the 31th, Sergey Makovkin (Fly) ceased development of his client/server modification of ZDoom 1.22, csDoom. Nightfang used csDoom 0.7 as a base for his own port named ZDaemon and released ZDaemon 0.8 on February the 20th at www.truelights.com. On March the 11th, March the 12th, June the 2nd, June the 18th and July the 5th, versions 0.9, 0.92, 0.95, 0.96 and 0.99 were released, respectively.

2002

In March, the ZDaemon homepage moved to www.zdaemon.com. To improve the network code for ZDaemon 1.0, Nightfang rewrote the core netcode, which eliminated the GPLed QuakeWorld networking code that Fly incorporated in csDoom and thus resolved the conflicting licenses that ZDaemon inherited from csDoom (GPLed Quakeworld code and DSLed ZDoom) and allowed the developers to include code from ZDoom 1.23 and later versions without conflict. The ZDaemon core codebase was update to ZDoom 1.23 beta 33, which, among other things, added support for Heretic and slopes. ZDaemon 1.0 was released in November, followed by ZDaemon 1.02 a few days later and ZDaemon 1.03 in December.

2003

In early 2003, the ZDaemon homepage moved to www.zdaemon.org. In April, ZDaemon 1.04 was released followed by ZDaemon 1.04c and ZDaemonGL 1.04 in June. Shortly thereafter, Nightfang retired from the ZDaemon project and Raider became the new project leader. In August, Kilgore joined the team and started working on a teamplay mode for ZDaemon. Furthermore, a gradual rewrite of the netcode was carried out over the following major releases. ZDaemon 1.05 was released in October, bundled with GetWAD for automatic WAD downloads.

2004

In March, ZDaemon 1.06 was released and after numerous point releases throughout the year the last version where the source was available, 1.06.08, was released in November.

2005 - Today

Starting with the 1.07 release in July 2005, the ZDaemon project does not make the source code available anymore and has remained closed source from that point forward (see Source Code). In August 2005, ZDaemon 1.07.01 was released and unlagged support was added. In December 2005, ZDaemon 1.08 was released. For more information on the following releases and the most recent release read the ZDaemon Changelog.

Cheating
For the most part the ZDaemon team has managed to keep cheating relatively under control through closing the source, security updates, and surveillance (for instance, demo recordings are often demanded during competitive tournaments to combat cheats like aimbots, or wallhacks). ZDaemon contains also some kind of cheating detection system which detects third party cheat applications.

The cheating policy is a point of contention within the ZDaemon community, as public accusations of cheating (whether legitimate or not) are frowned upon as unnecessary public disturbance, with Raider once declaring it as a form of harassment. This has led to conflicts in the community, including many by long-standing members who feel there are a small number of cheaters who evade the ZDaemon's cheat detection system, which they feel is either ignorant of the matter or simply turning a blind eye. The administrators maintain that they ban only when given clear evidence by their cheat detection system and stand by their policy, although their critics argue that this is done under color of authority.

Source code
In the ZDaemon 1.07 era, having forgone the nominal GNU GPL by explicitly adopting the DSL which they told to be fully compatible with the then-current state of the source code, the development team stopped releasing the source code due to numerous exploits and cheating incidents. This action caused a couple of free software friendly people to distance themselves from the ZDaemon community, criticizing the move as a form of security through obscurity, which makes development of some cheats more difficult but does not address the causes. The move also makes development of alternate ZDaemon clients and servers impossible, and is uncommon in the Doom community where most source ports have their source code publicly available. Skulltag, a formerly closed-source multiplayer-oriented source port, faced the same criticism until it was opened. Full source code for that port's offspring Zandronum is now available. ZDaemon has also its old 1.06 code base released. Odamex, the last multiplayer-oriented port, is and has always been free software under the GPL.

The developers have agreed that anyone wanting to develop a new feature or bugfix may do so using the older ZDaemon 1.06 codebase and submit it to the core development team for inclusion.

Bans
The ZDaemon master server will only advertise servers that enforce a ban list controlled by the ZDaemon staff. Servers that do not enforce this ban list are not shown to users. The effective result of this is that the ZDaemon staff have the ability to ban anyone they choose from all ZDaemon servers advertised on the master. No ban list (or other) restrictions apply to servers not advertised on the master. While this allows the removal of cheaters, the mechanism used can occasionally block innocent players as well due to matching dynamic IP ranges. Even when this kind of system has its cons, it's still very common banning method and other ports, like ZDaemon's main competitor, Skulltag, are using same system.

Ban appeals, especially those of bystanders caught in the range bans of others, often end up as over-dramatized forum posts. For this reason, it is usually requested that such appeals be relegated to a private dialog with a member of the staff.

GetWAD
Doom source ports require a Doom IWAD file which contains the graphics, levels and other media that are used in the game. These IWAD files are still copyrighted. This means that although source ports can be freely downloaded, users must still buy a copy of Doom in order to play. The GetWAD system included in ZDaemon allows any WAD files to be automatically located and downloaded, including IWAD files. There are no restrictions placed on this. Although this practice is not officially condoned by the ZDaemon staff, some consider failure to prevent automatic downloading of the Doom IWAD files an encouragement to piracy.

Fake aimbot trojan
ZDaemon staff member Doom2pro released a trojan program, purporting to be a ZDaemon cheat, in a global cheat developing forum to trick regular cheaters to download it. When run, the program would inform Doom2pro and delete the ZDaemon folder from the user's computer. Although Doom2pro acted independently of the rest of the ZDaemon staff, ZDaemon has nonetheless been criticised for his methods.
