I'm trying to resume TLS/SSL session from the FTP control socket on the transfer socket. Some FTP servers started to require this. E.g. vsftpd: https://scarybeastsecurity.blogspot.com/2009/02/vsftpd-210-released.html I'm using OpenSSL to implement SSL layer.

How can I send the close_notify alert manually? 回答1: Thanks for this question. It pointed me into the right direction, that there is a bug in .Net, which I do not very often think about. I bumped into this problem during writing of my implementation of FTPS server and Filezilla (or GnuTLS probably) client was complaining "GnuTLS error -110 in gnutls_record_recv: The TLS connection was non-properly terminated". I think it is a quite significant drawback
