The only clue I see is "Restricted user logged in." Maybe it booted you on the list command?
Or if this is new behaviour, a common thing for people to do is close off all but known ports. That port 50243 is a likely one to be closed.
G'day. I tried to connect to my Web Server(remote) using ftp but received the following error messages:
LOCAL -> Connecting to (sinaran.net*****.com).
LOCAL -> Connected to (sinaran.net*****.com) -> IP: 204.92.xxx.xxx PORT: 21.
LOCAL -> Socket connected waiting for login sequence.
REMOTE -> Ftp server ready.

REMOTE -> User xxxxxxx okay, need password.

COMMAND -> LIST -a
ERROR -> Cannot connect to 218.208.xxx.xxx:50243 - Connection refused.
ERROR -> Connection closed.
Where 218.208.xxx.xxx is my PPPoE IP Address. My Internet gateway server is RedHat 9 while the client is Win98 PC. If I connect directly from the server(RedHat), there is no problem.
Thank you in advance for your help.
