And in the server say this error

[iNFO] Disconnecting XXXX [/127.0.0.1:8652]: You don't have FML installed, you cannot connect to this server

but when I connect using a clean client, this connect correctly, but send the error "bad login".

 

You can help me?

When you mean server do you mean clientserver, OR do you mean like a vanilla Minecraft server?

 

If so...

You don't have FML installed, you cannot connect to this server

I used forge server,

this message send me the server

You don't have FML installed, you cannot connect to this server

Are you even sure you installed Forge on the server correctly? It isn't the same as client installation...

yes, forge is installed in server correctly, I can connect if put online-mode=false, but not if online-mode=true

If i connect with clean forge client with online-mode=false, this connect correctly

if I connect with mod forge client with online-mode=false, client close with error, and in server say "You don't have FML installed, you cannot connect to this server"

Well obviously, if your Forge != Server Forge, then it wouldn't work.

client forge client , mod forge client and forge server are installed from same file , all are forge v9.11.1.965

In mod forge client, I only modify bcw.class file, I replace url of session verification.

I can modify varius *.class files in jar file, but when modify bcw.class I receibe the error

 

2014-02-19 22:15:32 [Grave] [ForgeModLoader] There is a binary discrepency between the expected input class bcw (bcw) and the actual class. Checksum on disk is 16139a0f, in patch 10849a00. Things are probably about to go very wrong. Did you put something into the jar file?

2014-02-19 22:15:32 [Grave] [ForgeModLoader] The game is going to exit, because this is a critical error, and it is very improbable that the modded game will work, please obtain clean jar files.
