there isnt much difference between those 2 images i think, what exactly do you want to change? to make something like if you didnt enter the correct code in 1 minute then you can not do it anymore and u are jailed or something like you have only got 1 chanse to type correct code or what else?

I think that the second1 cannot be bypassed as i had post it to L2 Net Forum and i did not taken any answer ;) ..!

 

In other Words I Want to make it More Safer .....

 

 

Thats is why i said "Listening all opinions / advises ...!"

computers are not so smart to read an image, if it was a string text, yea is posbile ofc..

 

This way to protect server from boots is sh1t.

i want to play not answer everytime in stiuped pop ups...

 

i remember that way from l2ownage before 1 year, every 15-20 min pop up ... really make you angry xD

[vampir]

you could have those images in server same as crests so players wont have them in their client, but i dont think that it would change a thing

 

As i can see from their code, they have check:

IF "HTML.CONTAINS #$CAPTCHA" == TRUE

you could change $captcha in your code to what ever you want just to players dont know it, if they cant check whats there then i think it should work.

Edit :

 

//CODE & CONCEPT BY Phear3d
//Written August 25, 2010

SET_EVENT "<&SCRIPTEVENT_SERVERPACKET&>" "<&SYSTEM_CURRENTFILE&>" NpcHtml 25
BLOCK 25
PRINT_TEXT "Captcha script is running!"
WHILE ZERO == ZERO
SLEEP 2000
WEND
END_SCRIPT

FUNCTION NpcHtml
  DEFINE INT PacketType 0
  DEFINE INT ID 0
  DEFINE STRING HTML ""

  PACKET.READ_BYTE PacketType
  PACKET.READ_INT32 ID
  PACKET.READ_STRING HTML

  IF "HTML.CONTAINS #$CAPTCHA" == TRUE
     NPC_DIALOG "bypass -h voice .CAPTCHA LOL LOL"
     PRINT_TEXT "Captcha Bot Check Found"
     JUMP_TO_LABEL THE_END
  ELSE
     INJECTBB_CLIENT PACKET
  ENDIF

LABEL THE_END
RETURN VOID

 

This is the solution some1 gives For L2 Net to bypass this protecrion ;)

Well it might be really boring and stupid but i think it is the only way to pretect a server from boting except paying for LameWare ;) ...!

The old one was very simple to bypass bcause was used client letters...

Very simple they decleare Letters Link ...

 

But as i say, there are new-customs images...

Why you lose time on PvP Servers? BTW i see ppl ask for PvP Server protection methods...

Personaly i dont lose my time with PvP Servers...

[Tryskell]

If you used integrated images from client, such as numbers 1 to 9, basically the system would be easily bypassed, as phx could sniff the name of images, then doing a script you enter it automatically.

 

The only possible way is to get the full image to be generated randomly, such as catpcha. So external to the client.

 

After the protection comes only about the captcha system itself. Use another system.

General discussion :

 

What the point about capcha, it's good only to spot a "bot", so in a pvp server, it's totally useless.

 

You stay out of your computer to go shit, you're banned because you weren't at time xx to enter a popup ? Clearly, stupid system.
