How to make yourself admin, the kick and ban commands that work on a vanilla server, the 1.0 ID change that broke admin lists, and why devcommands is refused on a dedicated server — with the three real workarounds.
World modifiers are launch arguments on a dedicated server, not a menu. Every preset, modifier and key with its exact spelling, the ordering rule that silently undoes your changes, and how to change the rules on a world you already play.
Two files and a name: where the .db and .fwl live on every platform, where to put them on the server, the password rule that blocks the start, and why characters come along for free.
A Valheim server’s memory tracks your world, not your player count. What the 1.0 server really uses, measured, and a sizing table for 4GB, 6GB and 8GB.
Console players, a new world version, the Deep North, performance notes with a caveat, and mods on shaky ground — plus the update sequence that keeps a mixed PC and console group from being locked out.
The complete 1.0 dedicated server guide for Linux and Windows: SteamCMD install, every launch argument, the crossplay flag console players need, the password rules that silently stop a server, systemd, updates and admin lists.
BeamMP has no built-in voice chat. Here is how players actually talk in 2026: Discord, BeamVoice, and proximity voice built into Connect servers, with setup steps for owners and players.
BeamMP has no server password — "private" means unlisted plus a whitelist. Two ways to set one up: a hosted server that is private in a minute, or self-hosting with Private = true, port forwarding and direct connect.
The admin command list as it actually stands on Build 42.20 — becoming admin, the seven access levels, the console-vs-chat slash rule, daily-use commands by job, and the B42 changes (capabilities, new item IDs) older lists miss.
The practical walkthrough of the ~20 keys admins actually change — identity, PvP, PauseEmpty, backups, mods — plus the SandboxVars world rules, the stop-edit-start rule, and which choices are world-permanent.
Your B41 world can't come to Build 42 — but your settings mostly can, and your group definitely can. The honest carry-over table, the fresh-start path, the legacy-branch option, and the backup to take first.
Build 42 moved the floor: ~6GB before a single mod loads. The sizing table by group size and mod count, the JVM -Xmx 75% rule, and how to recognise GC stutter before you buy the wrong upgrade.
