Sven Co-op server quick reference: GoldSrc engine, and the dedicated server appid 276060 runs natively on Windows and Linux with no Wine involved. The official table registers three transport flows: 27015/UDP (parameter -port) carries game traffic, custom content transfers and remote console RCON all at once; 27015/TCP is the legacy RCON path and the official page marks it legacy, no longer necessary; 26900/UDP (parameter -sport) is Valve anti-cheat VAC service traffic that auto-increments to the next available port when taken, so 26900 is only a start value. RCON has no port of its own; the secret lives in rcon_password inside server.cfg, and leaving it blank disables remote console access (the official page stresses this does not let everyone in). Every config file sits under the svencoop folder: server.cfg, mapvote.cfg, skill.cfg, banned.cfg, listip.cfg, mapcycle.txt, motd.txt, admins.txt, default_plugins.txt and the logs folder, and server.cfg is only read if you declare it on the command line with +servercfgfile. admins.txt holds one STEAM_X:Y:Z per line (not a 17-digit SteamID64), a leading asterisk marks the owner (the official page says that is mainly for show with no extra powers) and a hash starts a comment. This game has no Steam Workshop: the official FAQ says integration is planned for the future and is not currently a high priority, so custom content is served over HTTP via sv_downloadurl and sv_allowdownload. The launcher is svends_run on Linux or SvenDS.exe on Windows, not the Source family srcds_run. There is also one outbound requirement: the server or an upstream firewall must permit HTTPS (TCP 443) to gameinfo.svencoop.com. The official documentation is the seven-page Running a server section on wiki.svencoop.com covering installation, starting a server, configuration, connectivity, advanced topics, installing custom maps and the overview.

Sven Co-op Ports & Protocols
| Port | Protocol | Purpose |
|---|---|---|
| 27015 | UDP | Game traffic, custom content transfers and RCON all share this single UDP port |
| 26900 | UDP | Valve anti-cheat (VAC) service traffic. 26900 is only the start value: if it is taken the server auto-increments to the next available port |
| 27005 | UDP | The Steam client communication port. The official port table does not list it; only LinuxGSM passes it explicitly, so this site marks it optional |
