    ChatNode TEMP. Crash (All Channels)

    Execute the following iptables role in your CentOS:

    Code:
    iptables -A INPUT --match string --algo kmp --hex-string '|E2 B7 0E 00 00 00 00 00 35|' --jump DROP
    This is a temporary solution!
    I do not know if there are other hexes. If you find out, comment.
    I'll post a definitive solution as soon as I have the edited .bin.

    EDIT:

    ChatNode crashfix:

    Edit WorldSvr.bin:
    747FC785FE ---> EB7FC785FE

    Edit your WorldSvr_xx_xx.ini :

    #ImageAuth
    UseBotCheckSystem=0
    UseImageAuth=0
    ImageAuthDataPath=/etc/cabal/ImageAuth/
    UseBotCheckInCharacterSelectLogout=0
    UseSharedImageAuthData=0

    Excellent job Niicke, now let's wait for the next bomb to bring down Channels, people like to launch diseases and then charge money for a cure.

    This modification prevents the channel CRASH. It is an attack that relies on sending an invalid packet to your server and disconnecting all players.

    Did you make the modification in the channels as taught in the topic? Did you close the GlobalMgrSvr port for external access?

    If you really think closing that port prevents the mail bit etc then you're horribly wrong I'm afraid.
