27/9/2006 13:21:38: XXXXXXXXXX YYY (A.B.C.D:E) - To be able to connect to big edonkey/emule servers, you MUST use emule 0.47c and activate obfuscation


Any chance we can have a alpha Morph v9 release ?

Alert came from DS2 62.241.53.16

I think the server checks for the emule version, if I try to connect again it simply times out.

Edit: It seems thereīs a problem with the server, I tried using Xtreme 5.3 based on 47c, enabled protocol obfuscation and I still get the same message.

No problem in servers, it seems that they want to fight eMule traffic blockers, so they force us to use obfuscation protocol, which will change standard eMule packets (That can be identified by any traffic analyzer program) to Random Packets (Impossible to detect packets contents).

Its a nice feature from eMule team, we are waiting Morph MOD team to upgrade thier version to eMule 0.47c, to use this feature. :+1:

Not a problem with the server, but with the mod itself. Since this kind of complaint is becoming frequent, I will explain here what a 'mod based on emule 0.47c MUST respect (as the original 0.47c client)'

The connection from server to a client backdoor is optimized to take the minimum amount of frames.
This optimization is done only for new clients (that assert OBFUSCATION support, but not necessarly OBFUSCATION requested)

Take a sniffer, you'll understand.

First SYN from server to crypto client
18:51:28.098030 IP Server.39873 > Client.50300: S 3464942699:3464942699(0) win 5840 <mss 1460,sackOK,timestamp 2295742364 0,nop,wscale 7>

client ack the SYN
18:51:28.288131 IP Client.50300 > Server.39873: S 889304976:889304976(0) ack 3464942700 win 65535 <mss 1412,nop,wscale 2,nop,nop,sackOK>

Here you can see eserver is smart enough to send the crypto challenge inside the 3rd packet, where most applications just send a ACK packet without data, then another packet with only the data
18:51:28.288163 IP Server.39873 > Client.50300: P 1:16(15) ack 1 win 46

Here emule sends the crypto answer
18:51:28.457999 IP Client.50300 > Server.39873: P 1:22(21) ack 16 win 64242

Here eserver sends the HELLO frame , AND the FIN flag to tell the remote peer that no more data will be sent in the socket.
THIS is the tricky part, because emule might see the FD_CLOSE event before handling data. To get a HighID, a client MUST answer this HELLO frame BEFORE closing the socket. For sure, emule 0.47c is doing the right thing
18:51:28.458030 IP Server.39873 > Client.50300: FP 16:80(64) ack 22 win 46

Well... windows is not clever since it sends this ACK packet with no data...
18:51:28.555061 IP Client.50300 > Server.39873: . ack 81 win 64226

Here emule 0.47c sends its HELLOIf your 'mod' does not this but just close its socket, THEN it's not a 0.47c mod, but yet another thing that lies
18:51:28.557418 IP Client.50300 > Server.39873: P 22:129(107) ack 81 win 64226

Here emule sends its FIN (while it could have been incorporated in the previous packet)
18:51:28.558311 IP Client.50300 > Server.39873: F 129:129(0) ack 81 win 64226

eserver acknowledge the end of communication
18:51:28.558316 IP Server.39873 > Client.50300: . ack 130 win 46


Thats a total of nine frames (if crypto exchange), or seven frames if not obfuscated communication.
If windows was smart, 2 frames could be saved (in blue color see below)... but unfortunatly windows is not so smart.

P.S. Maybe eServer v17.14 and higher detects does the client's ISP shapes/trickles p2p connections? confused.gif Is it possible?


Yes its possible, but unfortunatly the server cannot tell the client, since a client that attempts a non obfuscated connection wont receive the warning messages from server (they are filtered by ISP)

hmmm.. Iīm sure Xtreme 5.3 works the same way as official.

I connected to many servers (obfuscated and non obfuscated) and never had any problem.

@lugdunummaster:
As I understand, you speak about 0.47c-based clients. But Carlos113 and me using same mod: 0.47a MorphXT v8.14 and my client connects to ANY server without any problem, while Carlos113 - not. What's the difference? :confused:

Since it happens on 8.14 to Carlos113 which is 0.47a based this message seems to appear also on something other than SRV_TCPFLG_TCPOBFUSCATION tag?

Note that I myself can connect fine with 0.47 (& 0.47c unreleased) morph mods, so the report from Carlos113 is not reproducud by me. Something other seems to happen?

@carlos113: what isp & what router are you using? Or if you have this message on 8.14 could you sniff out the packets that are send to the server? (and if you have problems intepreting them, post them here?)

Download the MorphXT emule mod here: eMule Morph mod

Trouble connecting to a server? Use kad and /or refresh your server list
Strange search results? Check for fake servers! Or download morph, enable obfuscated server required, and far less fake server seen.

The IP, 190.16.xx.xx -> fibertel.com.ar (/edit by leuk_he)
No router.

Itīs the ony server I had problems with, the few I tried AFAIK worked fine.

"Donkeyserver1," for example has no problems regardless of what client I use.
Although "Saugstube" says that my IP is in the IPFilter. dat, after that it connects fine anyway :confused:

Iīll post what I find in the next post.

Edit, turns out Itīs a bit harder than I thought, what do I have to post? lol
Thereīs a lot of stuff in there.

He didn't want to know your IP. He wanted to know what ISP you are using.

Btw what IP does DS2 have on your server list?

Seven for the Dwarf-lords in their halls of stone,
Nine for Mortal Men doomed to die,
One for the Dark Lord on his dark throne
In the Land of Mordor where the Shadows lie.
One Ring to rule them all, One Ring to find them,
One Ring to bring them all and in the darkness bind them
In the Land of Mordor where the Shadows lie.

It might be wise to not post your own ip. So i changed your post. Posting the ip of proxies// servers is usefule and does not threathen your privacy.

Ah sorry I read IP instead of ISP, thanks :b: Yes itīs Fibertel, a big one here and I never had problems with them and p2p so far *touches wood*

The server DS2 appears as 62.241.53.16:4242

Edit: tried the official client and now it connects to DS2.

Fibertel sucks... they've been implementing drastic measures against p2p programs, emule included (bt also)... and they've been doing it in different zones of Buenos Aires at different times. You should definitely check out this forum:
http://limitacionp2p.cjb.net There you'll find your answer.

Currently bittorrent works fine when I download from certain places, and emule has no problems either, I can upload at 26KB/s without much problem.

The only time I had a problem with them was when UL/DL connections were being dropped for no apparent reason, this happened to other people too, you probably remember it, a campaign was starting to appear to get them to "fix" this but before much happened the problem dissapeared.
Since then I never had a p2p problem with them, so I doubt that the current problem is completely related to them, after all the official client works fine.
