Is ConnectSSL with port 27 impossible?

Question

Hi,

I am testing your library and have successfully connected to several ftp servers. However one is set up using TLS/SSL with port 27 and I just want to verify if this at all is possible with your library?

Thanks
Sten

Answer 1

The default FTP port is 21.
FTPS (FTP over implicit SSL/TLS) uses port 990 by default.

You can use Connect and ConnectSSL method overloads to connect using a different port:

ConnectSSL("ftp.example.com", 27);
