[TriLUG] ftp question.

[Ian Zhang]

I got a linux box behind a cable modem router.  I tried to ftp to my 
cable IP address.   I can login.  But when I do the "ls" command under ftp,
I got the following error:


331 Please specify the password.
Password:
230 Login successful. Have fun.
Remote system type is UNIX.
Using binary mode to transfer files.
ftp> ls
227 Entering Passive Mode (192,168,2,90,46,103)
425 Security: Bad IP connecting.
ftp>


Could anyone know whatis going on?

Thanks,
Ian
