Name having only 1 character lenght

[Reducto]

How can I fix this because some of my players having only 1 character name. They can bypass the 4 limit character. How can I prevent this?

diff your client with Disable4LetterUserCharacterLimit, Disable4LetterUserIDLimit, Disable4LetterUserPasswordLimit

I mean I want to prevent players having 1 character name lenght. How can I prevent it.

There's this: trunk/conf/login_athena.conf

//If new_account is enabled, minimum length to userid and passwords should be 4?

//Must be 'Yes' unless your client uses both 'Disable 4 LetterUserID/Password' Diffs

new_acc_length_limit: yes

but currently there is no server-side check for character name lengths.

With sql server you can add a contraint

DATALENGTH(Charname) >= 4

Something like that

 

With mysql you can do a check when the char is create :

I using RagexeRE 2012-04-18a, tried old version to make less than 4 length char name (using 'enter' 5 times on notepad and copy-paste it. ),

the result

 

Foul Language Detected

maybe

on char.c:check_char_name

 

/**

     * The client does not allow you to create names with less than 4 characters, however,

     * the use of WPE can bypass this, and this fixes the exploit.

     **/

or maybe you can use Regex to check there's any whitepace (or only enter/newline) there, the result is

1 = found,

0 = not found

SELECT 'name' REGEXP '(\n+)'

and btw, LENGTH calculate everything there of course whitespace will be counted. Edited April 27, 2013 by Cydh
