i wannna stop these:

strongdc, reverse connect

and this ldc++

Thanks, qaz

[qaz]

sorry to bother but is there any way to stop those clients...

if they show their real tag, then yes. then a ordinary client checker can do it.

[Dessamator]

hmm, PPK could probably write that, each client has a specific supports arrival, and most are unique, it doesnt matter what tag u have     (i think)

[PPK]

StrongDC++, LDC++ and maybe zDC++ is not problem to detect... but Reverse Connect is for hub same as DC++ and i don't know if is posible to detect it with counting connection request (multisource client sending more request than normal client)

do you mean this =
MultiConnectToMeArrival(User, Data)      - Incoming multi connection request from user. If script return 1 hub don't process data.

[Dessamator]

indeed !

[Pothead]

If you can implement LUA sockets in your script, you MAY be able to try and pretend that your script is a Kalmadia client.  Reverse connect will respond differently that DC++ to this.  Dunno if it's possible to do though, via LUA.

then shouldn't this be enough to stop the multi-source clients? =

-- Simple anti-multi source clients

MultiConnectToMeArrival(user,data)
	if not user.bOperator then
		return 1
	end
end

No MultiConnectToMe is from old NMDc client is used (but i never see it working) to connect to user on another linked hub. Multisource client sending more $ConnectToMe and $RevConnectToMe commands ...

ok, to bad but is it possible to add this future to ptokax? Or cant ptokax see the difference between $ConnectToMe/$RevConnectToMe spam and multi-source client user??

[Dessamator]

well, i had meant b4 analysing the supportarrivals of each client, but i thought that other method would work, either way, from what ppk said, i guess u can count the number of connection request  in a certain time pr something, compare to them to the norms, and kick them out if need be .

Some clients have special description tags and most of the users use them turned on. They may be detected from these descriptions and tags..

I am using a script that I butchered from Anti-rmDC++ script and its aliases, and most of the time its successful.. People know LUA better than me should feel free to show me if I am wrong or edit the script to help me learn..

Yep, it might work for users who dont care for changing the description and stuff, but its not "full proof". As a temporary measure it might be suitable until a way to block them completely, is found !

just a few comments on your script ;)

The way you use to detect those clients is just ordinary client checker, which cant see through dc++ emulation.
its better to script what clients you want to use and disconnect all others.

And as you meantion in the script description, anti-RMDC isn't  needed any more.

And I personally think this is a faster and better anti-mldc function =

function MyINFOArrival(user,data) 
	if user.bRegistered==nil then	
		if string.find(user.sDescription,"mld(%S+)") or string.find(user.sDescription,"edonk(%S+)") then
			user:Disconnect()
			return 1
		end
	end
end

Maybe wrong, but i think the newer ptokaX block MLDC's anyway. :)
Or it might be that the min share bugs are actually sorted. (they always have 11mb, but seem to get around all older hubsofts minshare settings.)
StrongDC can be blocked via supports as well as rm.  There is some post on this forum by PPK saying how to do it. :)

This is my second script trial on LUA and I need any kind of comments, and thanks for yours

I have to see the full login sequence between hub and client like

Hub:	$Lock EXTENDEDPROTOCOLuLUX7n^Bm:3DvTgGcGXUL4=mFVxiv Pk=PtokaX
Client:	$Supports MiniSlots XmlBZList ADCGet TTHL TTHF GetZBlock ZLIG|
Client:	$Key ?????A ????0????????u?w#"3BB????/%DCN005%/?
??|$ValidateNick TestUSER|$Version 1,0091|
Hub:	$Supports HubINFO
Hub:	$Hello TestUSER
Client:	$GetNickList|
Hub:	$NickList ...........
Hub:	$OpList ..........

(and also must have a large client archieve, but I have newly began to create my archieve so I lack info about them) to make a better detection script but I dont know how to see it (the sequence above is taken from HubList.org logs). Is PtokaX User/Chat screen enough?

$Supports UserCommand NoGetINFO NoHello UserIP2 TTHSearch QuickList GetZBlock|
[I]CZDC++ 0.666[G][/I]
$Supports UserCommand NoGetINFO NoHello UserIP2 QuickList|
[I]DC++ 0.670[/I]
$Supports UserCommand NoGetINFO NoHello UserIP2 TTHSearch GetZBlock |

Another thing to detect. DC++ sending $GetNickList before $MyINFO on login, CZDC++ and StrongDC+ after  :]

And if it is, my LUA knowledge is not enough to make a script detect special strings and their placement in supports That's why people knowing LUA better than me should feel free to show me if I am wrong or edit the script and add features to help me learn..

Yes PtokaX block 99.9% of mldc clients, they have bug in MyINFO... but here exist few without this bug (and diferent share size than the 99.9% of blocked) and for this is script needed

[Pothead]

Thanks for the info. I'll add it again.  :)

but that does only block strongdc right? not all multi source clients?

[Pothead]

Blackwings: Yes that only blocks strong and rm.  It was to be added to the other script posted, if wanted.

GeceBekcisi: That's because BigMuscle sorted out part of his client emulations problems.

[blackwings]

added CZDC just for fun =

end

[GeceBekcisi]

Then can you use "DC++ sending $GetNickList before $MyINFO on login, CZDC++ and StrongDC+ after" info to detect emulating clients?

[GeceBekcisi]

Isn't there any way to do this?


Edit:  I see most of MultiSource clients have show speed option resulting addition of [xxxK/xxxK]  or [xxxM/xxxM]  like things to descriptions. If there is no Non-MultiSource client having this as an option; this can be applied too.

Now the question is; is there any Non-MultiSource client having this as an option?

If no, why not giving a try on this?

[Pothead]

R2++ has this connection speeds, and is none-multisource.
