simpleadmin-web

A SourceBans-style web panel for CS2-SimpleAdmin (built against 1.8.2b's MySQL schema).

• Public site (/): the live server (name, map, players, team score and a scoreboard), bans, gags and mutes, and the staff list. Read-only. It never shows admin names, IP addresses or internal immunity values.
• Staff panel (/admin): sign in through Steam. Ban, gag, mute, silence, warn and kick; lift bans and blocks; manage ranks, permissions and staff; change server cvars and SimpleAdmin's punishment settings.

Live data comes from the WebPanelBridge plugin (plugins/WebPanelBridge in this repo) over RCON. Without it the panel still works, but shows the server as offline and can't kick or warn.

How it works

• Reading: straight from SimpleAdmin's MySQL tables (sa_bans, sa_mutes, sa_warns, sa_admins, sa_groups and their flag, unban and unmute tables, sa_players_ips).

• Penalties: sent over RCON as SimpleAdmin's own commands (css_addban, css_addgag, css_unban, css_warn, …), so they take effect in game at once, with SimpleAdmin's usual announcements, Discord messages and IP handling. SimpleAdmin records console commands as "Console", so the panel then rewrites that row to credit the staff member who did it.

• Game server unreachable: bans and blocks are written to the database directly, the way SimpleAdmin writes them. They apply when the player next joins (bans are also picked up by SimpleAdmin within about a minute). Kicks and warnings need the server.

• Ranks and staff: written to the database, then css_reloadadmins. A rank is a SimpleAdmin group (#rank/mod); staff are admins holding exactly one such group.

• Permissions: commands sent over RCON run as Console, which skips all of SimpleAdmin's own checks, so the panel enforces them itself with the same flags:

  Action	Needs
  Use the panel	@css/generic
  Ban	@css/ban; permanent or longer than MaxBanDuration also @css/permban
  Unban	@css/unban
  Gag, mute, silence, lift them	@css/chat; permanent or longer than MaxMuteDuration also @css/permmute
  Kick, warn	@css/kick
  See IP addresses	@css/showip
  Change map	@css/changemap
  Server cvars	@css/cvar
  Ranks, staff, SimpleAdmin settings, reload admins	@css/root

  @css/root grants everything. Nobody can act on a player whose immunity is higher than theirs, or on themselves, or give a rank with more immunity than their own.

Setup

1. Install WebPanelBridge on the game server (see its README).
2. Make sure RCON works: rcon_password set, and the panel can reach the game port over TCP. SimpleAdmin stores the server's address and RCON password in sa_servers, and the panel uses those unless SAW_RCON_ADDR / SAW_RCON_PASSWORD are set.
3. Copy example.env to simpleadmin-web.env and fill it in. SAW_BASE_URL must be the exact public address; Steam returns signed-in users there.
4. Put the panel behind HTTPS (a reverse proxy). Session cookies are marked Secure when SAW_BASE_URL is https.

Run it with podman:

podman build -t simpleadmin-web .
podman run -d --name simpleadmin-web --env-file simpleadmin-web.env \
  --user 1000:1000 \
  -v /srv/cs2/game/csgo/addons/counterstrikesharp/configs/plugins/CS2-SimpleAdmin:/data:Z \
  -p 127.0.0.1:8080:8080 simpleadmin-web

--user 1000:1000 matches the game container's user, which owns CS2-SimpleAdmin.json, so the panel can edit it. Mount it with :ro instead to make those settings read-only. Changes to that file apply the next time SimpleAdmin loads (a server restart). The panel keeps the previous version as CS2-SimpleAdmin.json.bak. It writes keys in alphabetical order, so expect a reordered file after the first save.

Or build and run it directly: go build && ./simpleadmin-web (Go 1.25, settings from the environment).

Rank names and colours

SimpleAdmin groups have no display name or colour, so those come from a site config (SAW_SITE_CONFIG, see site.example.json). The built-in defaults cover #rank/owner, senioradmin, admin, trialadmin, mod, trialmod, helper and guardian. Ranks marked "supporter": true are listed apart from staff and can't sign in unless they hold @css/generic.

Name history (optional)

SimpleAdmin keeps one row per SteamID + IP in sa_players_ips and overwrites its name on each connect, so a rename on the same IP loses the old name. sql/players-ips-name-history.sql adds name to that table's primary key, so every name a SteamID has joined with is kept and shows up on its player page and in name search. SimpleAdmin needs no changes. Run it once against the SimpleAdmin database; the file has the revert. Names are still only recorded at connect.

Limitations and caveats

• Tested against a real MySQL 8.4 with SimpleAdmin 1.8.2b's migrations applied, and a fake game server that speaks Source RCON and imitates SimpleAdmin's console commands. Not yet tested against a live CS2 server or live Steam sign-in. Things to check on first run: that RCON returns WebPanelBridge's output (it prints through Server.PrintToConsole, like css version), and that the cvar values on the settings page read correctly.
• In-game announcements for panel actions name "Console", because that's who SimpleAdmin sees. The database records the real staff member.
• Unban and lift act on the player: css_unban <steamid> lifts every active ban on that SteamID, as it does in game.
• Bans without a SteamID (IP-only bans from css_banip) are listed but can only be lifted in game.
• One server per panel. Set SAW_SERVER_ID if sa_servers lists several.
• Times are read in SimpleAdmin's Timezone (UTC by default), matching how it writes them.
