I have been using a copy of this code with minor modifications and it works beautifully.

I can't seem to find a way to find the IP address of a client as he tries to log in.

Is this possible?

Thanks in anticipation...

And that's good news, I think I'll have to do something myself, thanks for the message.

Hi all,
I have been testing the ftp server over the last few days with a new ip_camera from China.
In a local Ethernet environment all is well.
I then pointed the camera via ftp to my noip address. I have port forwarded the three ports.
Most of the time it works but I do get this error.

B4X:

this error does seem to be random.
