Configuring your client

Using DRASL - 𝙎𝙄𝙓𝙁𝙐𝙍𝙎 on the client requires a third-party launcher that supports custom API servers. Fjord Launcher, a fork of Prism Launcher, is recommended, but HMCL also works. Both are free/libre.

Fjord Launcher

1. Click your account in the top right and select “Manage Accounts...”.
2. Click “Add authlib-injector” in the right-hand sidebar.
3. Enter your player name and your DRASL - 𝙎𝙄𝙓𝙁𝙐𝙍𝙎 password or Minecraft Token, and use https://drasl.sixfurs.net/authlib-injector for the URL. Click “OK”.

HMCL

1. Go to the “Account List” view by clicking the account at the top of the sidebar.
2. At the bottom left, click “New Auth Server” and enter https://drasl.sixfurs.net/authlib-injector . Click “Next” and then “Finish”.
3. In the sidebar, click the newly-added authentication server, labeled “SIXFURS”. Enter your DRASL - 𝙎𝙄𝙓𝙁𝙐𝙍𝙎 player name and password and click “Login”.

Other launchers

Use the authlib-injector URL https://drasl.sixfurs.net/authlib-injector.

Or, if your launcher supports custom API servers but not via authlib-injector, use the following URLs:

Configuring your server

Minecraft 1.16 and later

On recent versions of Minecraft, you can use DRASL - 𝙎𝙄𝙓𝙁𝙐𝙍𝙎 on an unmodified Vanilla server. To do so, add the following arguments before you specify the jar file when you start the server:

-Dminecraft.api.env=custom
-Dminecraft.api.auth.host=https://drasl.sixfurs.net/auth
-Dminecraft.api.account.host=https://drasl.sixfurs.net/account
-Dminecraft.api.profiles.host=https://drasl.sixfurs.net/account
-Dminecraft.api.session.host=https://drasl.sixfurs.net/session
-Dminecraft.api.services.host=https://drasl.sixfurs.net/services

For example, the full command you use to start the server might be:

java -Xmx1024M -Xms1024M \
    -Dminecraft.api.env=custom \
    -Dminecraft.api.auth.host=https://drasl.sixfurs.net/auth \
    -Dminecraft.api.account.host=https://drasl.sixfurs.net/account \
    -Dminecraft.api.profiles.host=https://drasl.sixfurs.net/account \
    -Dminecraft.api.session.host=https://drasl.sixfurs.net/session \
    -Dminecraft.api.services.host=https://drasl.sixfurs.net/services \
    -jar server.jar nogui

Minecraft 1.7.2 through 1.15.2

Refer to the authlib-injector documentation on setting up a server.

Alternatively, you can patch your server to use a newer version of Mojang's authlib that supports the arguments for custom API servers. Replace the files under com/mojang/authlib in your server.jar with the files in authlib-1.6.25.jar.

Late Classic, Alpha, Beta, etc. through Minecraft 1.6.4

Use OnlineModeFix and start the server with the -Dminecraft.api.session.host argument described above. For example, the full command you use to start the server might be:

java -Xmx1024M -Xms1024M \
    -Dminecraft.api.session.host=https://drasl.sixfurs.net/session \
    -Djava.protocol.handler.pkgs=gg.codie.mineonline.protocol \
    -cp server.jar:OnlineModeFix.jar \
    net.minecraft.server.MinecraftServer \
    nogui
