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.
