WhiteList only

[OneGoogus]

How do you configurate the server as a no password and whitelist only server?

I have never tried it, but I suppose you could see what happens if you start the server with:

VALHEIM_PLUS=true
SERVER_PASS=""
SERVER_PUBLIC=false
VPCFG_Server_enabled=true
VPCFG_Server_enforceMod=false
VPCFG_Server_disableServerPassword=true

and add the client IDs to your /config/permittedlist.txt file.

I currently run with this, and just wanted to confirm that it works swimmingly.

Small note:
If you have public -1 set among server runtime arguments, it will eventually lead to users trying to connect to what shows up as a password-less Valheim server. It's not really an issue, unless a stranger discovers an exploit or bug to bypss the permitted list and get in.
I currently ship and inspect server logs to trend what versions connect, in the off chance that I might notice a new version appear. That'd prompt me that a server update may be ready.

Otherwise:

• Users not in the permittedlist.txt file (randoms, friends you haven't added to your list) may see a "Banned" notification upon connecting. That can be alarming for some folks. ;)
• If Valheim Plus is enforcing the mod with enforceMod=true, and/or the connecting client is using a different version, they first see an Incompatible Version error upon connecting, and won't see a "Banned" message.

You can look up 17-digit Steam IDs here or here

Edit: I'd suggest following a scheme like:

// List permitted players ID ONE per line
// Friend A
76561234567890123
// Friend B
76561234567890124

Thank you for confirming @kachunkachunk !
Preserving this as a discussion for others to find.

Also added the SERVER_PUBLIC=false suggestion.
