[Szponiasty]

Nice. Thx Janii for checking it out. This will open many new possibilities (not only for antibot)

If it really works, why isn't added permanently to l 2jservers?
A long time ago I didn't use l2j and I ask for initiation.

probably because retail servers don't have protection against bots

they do they have GM's lol look I made a joke

Yes, retail servers don't have it, but almost all admins don't want bots/3rd software on their private servers

[Moon]

It should be on l2j e.g. in l2jmods.properties mainly for this reason I am thinking whether to change the group l2j, since other grups (emu,official, matrix) are backing the protection of our servers up.

Perhaps do the probe to this topic, since you are doing wolfskins mistake in my opinion.
Surely each player wished to protect your server itself.
And if not, it should be an option on or off.

Quite a lot of thing, of which they are on l2j, there is no on the official server. This addition will certainly contribute to the even better popularity of your project of l2j!

I apologise for my words, but I am wanting what's best for oneself and for us everyone.

[janiii]

to make you all happy.. http://l2jserver.com/trac/changeset/4146

..but adding 3 lines of code should not be the most important when choosing a l2j server implementation, as you can add that 3 lines on your own too..

[Moon]

Im soo happy Ty!

At everyone update (requent update) to add the server 3 lines of the code + a lot of of one's additions is very troublesome, right? I am thanking you a lot one more time!

[qwerty13]

Useless. But i am not sure, need to check.

[Gnacik]

you have right. useless, nobody is using l2walker in fact :=D or in follow mode/buff only. the real problem is l2net because they have really active dev team.

[Moon]

At me on the server I detected so far:
Phx, pbx 3.4.1.82
Walker IG 2.17 with the independent program to "hide" before the scan.
L2Net as 384 bot OOG


As can be seen Walker is also also L2 used.
Better bit by bit to fight, than to do nothing - in my opinion.

[qwerty13]

IG bots with that protection works fine. So, for me it can be reverted, useless.

Server Gracia Epilogue protocol 146, Java
L2walker 10.9.8e OOG

Click in map, bot kick and have msg "You will be kicked for illegal action, GM informed".

Client packet

L2Walker send not full packet, when I send full client packet then bot run and not kicked.

Script for send full packet.

begin
if pck <> '' then
if fromclient and (pck[1]=#$0F) then
pck := pck + hstr('01000000');
end.
end;
end.

And L2walker good work.

How can a fix this and stop L2Walker? =)

[denser]

already told... guru-boters cant sopped via this way. only lamers...
so if you need to kill all over bots - you need to hire assassins or whatever active GM.

only way - it is intermediate server with traffic checks or encrypting
also this thing must protect process in memory and protect itself try to google kinda thing "checker.exe"
i dont try it on GE...but on earlier like interlude - it was perfect...worth author disappear...
