Soulseek Protocol Documentation

Last updated on April 28, 2021

As the official Soulseek client and server is proprietary software, this documentation has been compiled thanks to years of reverse engineering efforts. To preserve the health of the Soulseek network, please do not modify the protocol in ways that negatively impact the network.

If you find any inconsistencies or errors in the documentation, please report them.

Server Messages

Send to Server	Receive from Server

These messages are used by clients to interface with the server. Internal Server messages are spooky and not understood, since the OSS crowd doesn’t have access to its source code. If you want a Soulseek server, check out Soulfind. Soulfind is obviously not the exact same the official Soulseek server, but it handles the protocol well enough (and can be modified).

In museekd 0.1.13, these messages are sent and received in Museek/ServerConnection.cc and defined in Museek/ServerMessages.hh. Since museekd 0.2, they are defined in museekd/servermessages.h.

In Nicotine, these messages are matched to their message number in slskproto.py in the SlskProtoThread function, defined in slskmessages.py and callbacks for the messages are set in pynicotine.py.

Peer Connection Message Order

1. User A sends a Peer Init to User B.
   If this succeeds, a connection is established, and User A is free to send peer messages.
   If this fails (socket cannot connect), User A proceeds with an indirect connection request (step 2).
2. User A sends ConnectToPeer to the Server with a unique token
3. The Server sends a ConnectToPeer response to User B with the same token
4. User B sends a Pierce Firewall to User A with the same token.
   If this succeeds, a connection is established, and User A is free to send peer messages.
   If this fails, User B retries for ~1 minute. If this still fails, no connection is possible, and User B proceeds with step 5.
5. User B sends a Cannot Connect to the Server.
