Unable to pull dir LIST (SSL)

lbroxterman · Post by **lbroxterman** » Sat Dec 18, 2004 7:02 pm

I am using Core FTP and attempting to connect to a Seagull Security server which does the encryption and then push the Authentication to a backend Serv-U FTP Server (by RhinoSoft). I have successfully made WS_FTP and other 3rd party clients work however with CoreFTP the LIST of the remote directory timesout. The following is what I see in the log:
PASV
227 Entering Passive Mode (192,168,4,8,7,228)
LIST
Connect Socket #724 to 192.168.4.8, port 2020... timeout quit

Is this due to how the client is communicating to the server? Like I said I have successfully connected with other 3rd party clients such as WS_FTP, SmartFTP, and FTP Voyager.
The Security server establishes a TLSv1/SSLv3 connection. Any assistance anyone can provide would be a huge help. Thanks

Here is the complete log:

I am prompted to attempt a connection in the opposite mode (active/pasv). When I check no the quit command is sent successfully. You will also notice that I have replaced my external IP with x.x.x.x I feel no need to publicly announce my external IP. Hope this is ok.

192.168.4.8 is the internal IP address of the security server that points to the backend FTP server. I have attempted to add the NAT/IP in the configuration with the external IP but I got the same result.

Thank you for your assistance. I know I have attempted the NAT/IP address setting before without any luck however it seems to be working just fine now. I will continue to test for consistent successful connections and let you know if I have any other problems. Thanks again for the assistance with this issue it is greatly appreciated....
