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.

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.

could be your firewall is not allowing passive ftp. Upper ports need to be open to allow passive-ftp-data.

Thank you for your advice, Ppuru. How do I set the iptables to allow passive ftp in my case?
How do I open up upper ports to allow passive-ftp-data?
Thank you once again.

Actually there is no such thing as passive-ftp-data. Non-passive ftp connections use 2 ports to connect.
ftp - port 21 to connect and authenticate and ftp-data - port 20 to upload/download data.

Passive ftp too uses 2 channels - ftp - port 21 to negotiate the connection and upper ports 1024 or above for exchanging data.

If you have MASQERADING already in place, you may must need to load the ip_conntrack _ftp module using either modprobe or insmod on the RH9 gateway.

G'day. What I noticed was that when I used my Gateway Server (RedHat 9) to ftp, it connected at port 219.95.xxx.xxx:30xxx when I issued ls command & the connection was OK. Whereas, ftp with my Win98 client, it connected at port 219.95.xxx.xxx:50xxx & when I issued ls command, it said connection refused. Any idea?
Thanks.

Win98 ftp client does not support PASV ftp mode. I am not sure whether IE on Win98 supports Passive FTP ... you may need to set it in the Advanced Options.

Thank you for your help, ppuru. You're right, it's the passive ftp support problem. I can now use IE to browse my ftp site.
