500 invalid PORT Command when listing directory

by Viki » Sat Nov 17, 2012 8:05 am

Hello!

I really hope you can help me with my problem, because I have no idea what is wrong... In my program I'm trying to connect to a server with a ftp connection. There i first want to check if some folders already exist and if not, I want to create them. I can connect to the server with no problems, but when I want to list the root directory, I get an error: 500 Invalid PORT Command. I'm connecting to port 22, and obviously that is OK because the connecting part is OK. What could be the problem? Here the log:

I really have no idea why this is happening... If it helps - I am now trying to connect to a remote server (and I keep getting this error), but before (in first fase of development) I was connecting to a "server" within my home network with the same settings and it worked fine... The only thing I now changed are host and port....

I'd really appreciate your help.

Thanks :)

You most likely need to call setActiveIPAddress("your ipaddress")

OK, so I tried that, using my localhost IP and my "external"/router IP, but both times got the same error. I can connect to the server, but cannot read directory listings. This is how the log looks like:

You need to set the active IP address to an IP reachable by the server. It has to connect back to your client - 192.168 address is probably not going to work unless the server is on the same local network.

I understand that 192.168 IP would not work, so I tried setting my public (external) WAN-IP address as the active IP. But the error I get is the same. What am I doing wrong? As far as I know, a router has two IP's - LAN IP, for home network (192.168) and another one, which is for the external Internet connection. So if I understand everything right, this should be set as the active IP. Am I missing something?

Your firewall may be preventing the connection. You could try passive mode instead of active mode.
