Problem with FTP on SOCKS 5
Hi, I have encountered some problems with FTP and SOCKS 5.. I am trying to programm a Socks 5 Proxy, currently i have ALPHA 2.. nearly finished BETA phase.. I just want to add GSS but thats not very urgent. My problem is FTP.. i use Globalscape Cute FTP Pro 2.0 to connect to my FTP Server (127.0.0.1). It opens a control connection to my Proxy, my proxy connects to my Bulletproof FTP. But nothing happens. I have tried to solve the Problem by logging all things the Client sends and the server replys. [<--] 220 collective2k2 [<--] 421 Connection timed-out ! That's all the Server sends and the Server is no reply from the Client. And the Client has received the 220 msg from the server.. but he is not replying, nor trying to open a new connection through the Proxy or even connect to the Proxy without sending Socks messages. He simply ignores it and the server sends a timeout... Hope there is someone who knows these problems with FTP better than me. Just to add: My Proxy works perfectly with IRC, but not with FTP.. and some programs i wrote by myself that are according perfectly to the RFC 1928 standard it would help me if you knew some more programs that are using proxys. ICQ is one of these but it uses a UDP connection and my proxy is currently not able to handle UDP.. first I wanted to add these dammn FTP .. cu daniel
