Mostly abount Doom on Debian
Conclusion: zdoom is what I use for now.
The game in "The ultimate doom" edition is available from http://gog.com for $5.99.
Extract with "innoextract" (apt-get install innoextract):
innoextract setup_the_ultimate_doom_2.0.0.3.exe
It seems some of the engines requires special naming og wads:
"Chocolate Doom's main features are its accurate reproduction of the game as it was played in the 1990s." This includes high resolution with 320x200ish graphics.
https://www.chocolate-doom.org
apt install chocolate-doom
Setup including controls and resolution with:
chocolate-doom-setup
Run in window with:
chocolate-doom -window -iwad doom.wad
Press esc in game to get mouse and window manager controls back
For multiplayer, start server (and one of the players) with:
chocolate-doom -window -iwad doom.wad -server -privateserver
And join with:
chocolate-doom -window -iwad doom1.wad -connect IP-ADDRESS-OF-SERVER
Without the -window, it uses fullscreen.

apt-get install doomsday

"Never survives more than 20 minutes after installation. I will check this out in a year or so. John Romero uses this, seems he enjoys the superfiltered vaseline look. To me it makes Doom look like some game with shit graphics from 2000, only the lighting looks kinda good. Clusterfuck of options, I think it lacks Boom support, too."
Always run:
ctl-run 1

Note: seems great for single player, but not good for multiplayer...
"(gl)prboom-plus+: Best demo functionality, you can also convert demos to video easily. Excellent vanilla+boom support, runs super fast, I don't like the way the renderers look, the options are a clusterfuck and I hate playing with infinitely tall actors."
Install prboom (plus):
apt-get install prboom-plus
Download a wad, e.g. the original doom1.wad (I think it must be renamed to be lowercase if it's not already). Start:
prboom -file doom1.wad
Prboom is a bad server for internet play, but LAN is possible:
On the server (for skill level 1):
prboom-game-server -v -s 1 -w doom1.wad
Then on the clients:
prboom -net HOSTNAME-OR-IPADDRESS
with the correct hostname or ip-address (check with ifconfig) of the server.
If playing on the machine with the server:
prboom -net localhost

Doom (Strict): compatmode 2
zdoom -iwad doom.wad +set compatmode 2
Multiplaver for N players (including the server):
+set compatmode 2 -host N
By default, port 5029 is used.
To join:
-join IP
Save games is possible for multiplayer (save will save on all machines when one creates a savegame). To load use (for all players):
-loadgame SAVEGAME
Zandronum: This is a sourceport with a focus on multiplayer. An earlier version had some kind of admin backdoor, this seems to have put this port in bad standing.
