Insurgency: Sandstorm hosting quick reference: dedicated-server appid 581330 (type=Tool, oslist=linux, Linux-native only), base game 581320 (oslist=windows, Windows only). Three ports: 27102/UDP for game traffic (AMP ports.json "Server Port"), 27131/UDP for Steam queries ("Query Port"), 27015/TCP for RCON ("RCON Port"). Config lives in Game.ini (UE4 INI format, INSGameMode + INSMultiplayerMode two sections with 51 keys total) and server.cfg (Source-style cvar overlay). Running a server needs two tokens: GSLT and GSLTT (AMP config.json names them GSLTToken and GameStatsToken). Version anchor recorded as inferred: server buildid 24065441 and game buildid 24065399 were both updated on 2026-07-15 (49 seconds apart), and ISteamNews has a same-day patch announcement "Update 1.21 Operation: Breachpoint – Minor Patch", but the announcement uses game version numbers while appinfo uses Steam internal buildids, so the two numbering systems cannot be equated. Official documentation at insurgency.fandom.com returned 000 this round and newworldinteractive.com returned 403, so the full RCON command set, the precedence between the command line and Game.ini, and other details are all marked unverifiable.

Server notes
Dedicated server appid 581330 is Linux only (appinfo oslist=linux), client appid 581320 is Windows only. Running a server needs both GSLT and GSLTT tokens. RCON port 27015/TCP comes from AMP ports.json and is not forwarded by default. Config changes require a server restart. Official documentation at insurgency.fandom.com was unreachable this round (000); all facts come from AMP templates and LinuxGSM configs.
