Post subject: SubSpace Peer Protocol

Subgame has a "peer" function built in that allows game servers to communicate with each other. If you've ever wondered how they communicate (or you're just randomly curious about it), I've linked to a document from my project site:

SubSpace Peer Protocol

Enjoy!

is the crc32 password actually checked? how do they know the password of other zones?

Peers have to know about each other. Basically, you end up forming a trusted network based on a shared secret (the password).

To answer your question, yes, the CRCs are compared and the server admins are expected to share a common password for their peer network.

Isn't the CRC the same thing as the password? Knowing the CRC is enough to gain access to all of the functionality provided by the password. Seems a silly way to provide security.

that sounds about right

This is by no means a secure protocol. But if your peers are running in the same subnet or you can make sure that nobody's intercepting messages along the way, it's sufficient.

Then again, if we're on the topic of security and man-in-the-middle attacks, no communication channel within SubSpace is secure so we might as well get the benefits of a stateless protocol and have some way of rejecting 99.99% of likely attacks.

So while it's not theoretically secure, it's certainly good enough for the purpose it needs to serve.

Okay... and why have the servers to communicate with each other? What's the benefit?

I think it's to have multiple servers handle different arenas in a zone to split the load

Correct. This is probably how TW does or used to operate. ;o

Snrrrub, you're back in business now? I think last time I emailed you there was no response at the other end.

Doc Flabby: yes, this is related to your post. And also to *sendto.

Samapico: that's correct.

K': I was never quite out of business.

I must've just missed your email - sorry!
