    تفاوت بین FTPS و SFTP

    سلام رفقا
    از تیتر سوالم معلوم هست که چی میخوام.چه فرقی بین دو سرویس SFTP و FTPS هست؟ من فقط تو manual های SFTP روی لینوکس فهمیدم که برای انتقال فایل بصورت امن از روی پورت ۲۲ و بوسیله ی ssh استفاده می کنه و FTPS از SSL بصورت مستقیم استفاده می کنه!!
    ممنون میشم از دوستان گه بگن مزایا و معایب این دو روش نسبت به هم چی هست

    Is SFTP better than FTPS? What is the difference between the two؟
    answer:
    They are two completely different protocols.
    FTPS is FTP with SSL for security. It uses a control channel and opens new connections for the data transfer. As it uses SSL, it requires a certificate.
    SFTP (SSH File Transfer Protocol/Secure File Transfer Protocol) was designed as an extension of SSH to provide file transfer capability, so it usually uses only the SSH port for both data and control.
    In most SSH server installations you will have SFTP support, but FTPS would need the additional configuration of a supported FTP server.
    --------------

    FTPS (FTP/SSL) is a name used to provide a number of ways that FTP software can perform secure file transfers. Each way involves the use of a SSL/TLS layer below the standard FTP protocol to encrypt the control and/or data channels.
    مزایا Pros:

    • Widely known and used
    • The communication can be read and understood by a human
    • Provides services for server-to-server file transfer
    • SSL/TLS has good authentication mechanisms (X.509 certificate features)
    • FTP and SSL/TLS support is built into many internet communications frameworks

    معایب Cons:

    • Does not have a uniform directory listing format
    • Requires a secondary DATA channel, which makes it hard to use behind firewalls
    • Does not define a standard for file name character sets (encodings)
    • Not all FTP servers support SSL/TLS
    • Does not have a standard way to get and change file or directory attributes

    SFTP (SSH File Transfer Protocol) is a network protocol that provides file transfer and manipulation functionality over any reliable data stream. It is typically used with the SSH-2 protocol (TCP port 22) to provide secure file transfer, but is intended to be usable with other protocols as well.
    مزایاPros:

    • Has a good standards background which strictly defines most (if not all) aspects of operations
    • Has only one connection (no need for a DATA connection)
    • The connection is always secured
    • The directory listing is uniform and machine-readable
    • The protocol includes operations for permission and attribute manipulation, file locking, and more functionality

    معایب Cons:

    • The communication is binary and can not be logged “as is” for human reading
    • SSH keys are harder to manage and validate
    • The standards define certain things as optional or recommended, which leads to certain compatibility problems between different software titles from different vendors.
    • No server-to-server copy and recursive directory removal operations
    • No built-in SSH/SFTP support in VCL and .NET frameworks
