Hi Yil, thank you for your quick support

i`ve tested your instructions, but i get always the same error at login: 530 Login failed: Your IP/hostname is not authorized.

I want, if a user receives a new ip by his provider, ioftpd the ip updated independently.
Since then i`ve used the entry f.e. *@234.12.*.* but after a indefinite time he get a complete new ip-adress.
Can you look on my ioftpd.ini file, maybe i set wrong settings?

# fully qualified hostname hasn't even started yet (unless a cached
# answer is still around and valid). This is usually fine since you
# obviously can't be banned on the first attempt, but if you tried 10
# connection attempts all at the same time this might result in a ban

# Once the name has been resolved the next connection attempt will

# short amount of time (60 seconds per). This can easily be done in most FTP
# programs by just setting up fake ftp servers on the knock ports and trying
# to connecting in order, or by using the ioKnock GUI on windows machines.
# NOTE: You must connect in order! Thus using at least 3 non-sequential ports
# means a sequential port scan won't trigger the knock and produce a
# prompt on the real FTP port.

I`ve tested the knocking-feature too, but the error are the same...
