SSL and 503 FTP Error :: Socket
Hello.
I am working on a small socket application that utilizes SSL and FTP protocol. The problem is that the server response with error: "503 Log in with USER first." The SSL is OpenSSL. Here is an overview of the sequence. - winsock connect - AUTH SSL - SSL_connect() - handshake is success // At this point, everything is send/recv via SSL // SSL_send() and SSL_recv() - PBSZ 0 - PROT P - USER <username> - PASS <password> ... // All the above are successful // Server respond "230 <username> logged in." // Every command afterward returns an error - SYST Basically, every command the program sends, the server would return "503 Log in with USER first." Do you need to package outgoing data in a special SSL package before passing it to SSL_send()? Please post if you have any idea. Thanks, Kuphryn

If you are using SSL to connect to a non-SSL enabled server, you will get crap, plain and simple. Client and server MUST speak the same language and those apps that handle multiple protocols all have huge chunks of indepenant code for doing so.
