Hum i have another problem, i writed in ioFTPD.ini your line (EXEC = %EXEC c:\windows\system32\cmd.exe /c) and when i try to do: SITE EXEC something, it doesn't work and cmd.exe is in c:\windows\system32\
... So, the exec comand don't execute anything and i can write SITE EXEC gfdhgkfdgfd and i will receive 200 Command Successful.
