In case someone else would prefer to host in a more ping-friendly location, here is my Odamex conf:
sv_hostname "DosGameClub (Unofficial) - Doom (Revisit)"
sv_motd "Welcome to (unoffical) DOS Game Club server! Horde mode on Odamex"
sv_allowjump 1
sv_emptyfreeze 1
//sv_emptyreset 1
sv_friendlyfire 0
sv_freelook 1
sv_gametype 4
sv_maxclients 32
sv_maxplayers 32
sv_shufflemaplist 1
sv_timelimit 120
sv_unblockplayers 1
sv_usemasters 1
addmap map01
addmap map02
addmap map03
...
addmap map50
And the command I use:
nice -1 odasrv -host -port 10666 -iwad DOOM2.WAD -file hordamex.wad +exec dgc.cfg
