Minecraft 1.2.3 Super slopes Bukkit

I installed Super slopes on my Bukkit Server.
Preinstalled Modloader Mp and forge.
(World edit also installed)
When starting the Server, the Server loads the mods without any errors.

I also installed modloader and modloader mp with Super slopes v24 on my Minecraft Client.
Works on Singleplayer
The Problem is now, i can't connect to my Server
Other users can't connect too.
"Disconnecting /MyIp: Took too long to log in"
"Reached end of stream"

 

i had that first too, i thought i had craftbukkit 1.2.3 because i thought it was a RB but it wasnt, try this version of craftbukkit and it should work: http://forums.bukkit.org/threads/craftbukkit-1-2-3-r0-1-is-now-available.63380/

 

where can i get the right Modloader Version for this?

 

Where did you download Modloader 1.2.3?
