MSN tcp protocol issues

Problem/Question/Abstract:

More info about communicating with the msn service

Answer:

create additional features for the msn-delphi-clone found at torry's (see also my prev msn-article for also a ref to a delphi-code sample on torry)

[1]Connecting to msn server:

Connect: messenger.hotmail.com 1863
>>> VER 0 MSNP7 MSNP6 MSNP5 MSNP4 CVR0
<<< VER 0 MSNP7 MSNP6 MSNP5 MSNP4 CVR0
>>> INF 1
<<< INF 1 MD5
>>> USR 2 MD5 I example@passport.com
<<< XFR 2 NS 64.4.12.132:1863 0
Disconnect

Hier is MD5 het encryptie algoritme

[2]Get to the notification server:

Connect: 64.4.12.132 1863
>>> VER 3 MSNP7 MSNP6 MSNP5 MSNP4 CVR0

<<< INF 4 MD5
>>> USR 5 MD5 I example@passport.com
<<< USR 5 MD5 S 1013928519.693957190
>>> USR 6 MD5 S 23e54a439a6a17d15025f4c6cbd0f6b5
<<< USR 6 OK example@passport.com My%20Screen%20Name 1
>>> CHG 7 NLN
<<< CHG 7 NLN
Continue Session . . .

[3] Change status msn user:

>>> CHG 8 AWY
<<< CHG 8 AWY
>>> CHG 9 NLN
<<< CHG 9 NLN
>>> CHG 10 HDN
<<< CHG 10 HDN

[4] contactspersonen

There are four types of contact lists, each with a two letter code.

FL Forward List - Users on your contact list.
RL Reverse List - Users who have you on their contact list.
AL Allow List - Users who are allowed to see your status.
BL Block List - Users who are not allowed to see your status.

If there are no users on the requested list, the server will reply with 0 for both the user number and the total number of users, and there will be no fifth or sixth parameter. Below are some exampes of requesting lists.

>>> LST 10 FL
<<< LST 10 FL 21 1 3 example@passport.com Mike 0
<<< LST 10 FL 21 2 3 name_123@hotmail.com Name_123 2
<<< LST 10 FL 21 3 3 myname@msn.com My%20Name 0
>>> LST 11 BL
<<< LST 11 BL 3 0 0

[5] change your screen-name

>>> REA 25 example@passport.com My%20New%20Name
<<< REA 25 115 example@passport.com My%20New%20Name
>>> REA 26 example@passport.com fuck
<<< 209 26
