Will a Skype server ever become a thing?

If not, please tell me how to make 6 or early 7 work again.

EpicTaco404 · April 11, 2020, 3:57am

6 and 7 use msnp24, so i guess it could be suppoted on escargot sometime soon? and the servers for those versions are long gone, so they wont work on microsoft servers

EpicTaco404 · April 11, 2020, 4:18am

or atleast blocking their protocols

Versions of Skype before 6 use P2P but not sure about late versions of Skype 5

At this point everything up to Skype 7.x has stopped working (I’ve pinged the Skype 6/MSNP24 servers and they don’t accept connections anymore), so there’s no way to convince the clients to use official servers. As for Escargot supporting the protocols, we’ll consider it and we’ll possibly do more than the MSNP24 clients. Microsoft got the P2P Skype clients to work in a centralized environment with their own supernodes, so why not Escargot?

Sounds exciting, hope this happens in the future.

Searching around I found some interesting documentation of Skype’s MSNP24 protocol

github.com

# Skype protocol notes

It looks a lot like [msnp21](http://code.google.com/p/msnp-sharp/wiki/KB_MSNP21) with a different login process.

## Login

If you log in with a MS Account, you start (in the MSNP stream) by being referred to as `1:alice@hotmail.co.uk` and end up as something more like `8:live:alice_1`, 8 apparently being the namespace for Skype users. Looks like the [documented](http://msdn.microsoft.com/en-us/library/live/hh243647.aspx#implicitgrant) process for logging in to Windows Live, with scope `service::skype.com::MBI_SSL` (there's mention of ambientssl in later in the MSNP21 parts!) and client ID `00000000480BC46C`

Follow that, eventually you get a redirection to the URL you requested as the callback (Skype requests `https://login.live.com/oauth20_desktop.srf?lc=2033`) with a big fragment and a fuckton of cookies. Note that so long as you use Skype's client ID you pretty much [i]have[/i] to use that URL. WL will complain if you use anything it doesn't like, which is probably any other URL given that Skype is a desktop application.

```
access_token=<lots of base64>
refresh_token=<a bit less base64>
token_type=bearer
expires_in=86400
scope=service::skype.com::MBI_SSL
state=999
user_id=<a bunch of hex> // I guess this is one of the forms of UID that WL uses?
```

true, plz make that become true

Will the early versions of Skype be supported?

OhHelloThereImTheGuy · April 12, 2020, 2:51pm

That’s pretty much what I meant by the P2P versions… and if possible.

anon30772419 · April 12, 2020, 2:52pm

Hadn’t you said in the past the it would be hard for the escargot server to support intertwined p2p messaging?

OhHelloThereImTheGuy · April 12, 2020, 3:09pm

Yes, but that depends on how the P2P protocol is structured and if it contains enough data to proxy it from Escargot servers. In this case, while I haven’t seen the data for this, Microsoft was able to make their own supernodes for Skype in place of the P2P ones, so it might be possible to do Skype’s P2P protocol in a centralized environment. As for a protocol like early ICQ’s (before 2000a), isn’t possible because not enough identifiable data is sent to work with to set up proper chat sessions on the server side.

anon30772419 · April 12, 2020, 3:15pm

Gotcha.

Gabriella_Antunes · April 13, 2020, 6:33am

just to understand, you guys want to make skype contacts and messages work via MSN? for example I add someone that uses skype and I can talk via msn escargot server and the person will receive that on his skype?

OhHelloThereImTheGuy · April 13, 2020, 7:22am

Not exactly. It’s just for support of older Skype versions period. If or when Escargot does support it however, it’ll already be able to talk with contacts on MSN (and other supported frontends) since Escargot is going to become its own thing soon, where it’ll host a bunch of protocols and allow them to talk to each other.
