TCP/IP Connectivity Utilities for i5/OS commands - IBM

Allow secure sockets layer (ALWSSL)
Specifies whether the FTP server should use Secure Sockets Layer (SSL) support. SSL provides encryption
of FTP datastreams (including passwords), and optionally supports certificate-based authentication of FTP
clients (which allows the user to be authenticated by certificate instead of password).
*SAME
The allow secure sockets layer value that was previously set does not change; otherwise, *YES is
used.
*YES The System i FTP server accepts non-SSL FTP sessions. If the prerequisite products needed to
allow SSL support are installed and a valid FTP server certificate is configured in the Digital
Certificate Manager, SSL sessions will also be allowed.
Note:If ALWSSL(*YES) is specified and the Digital Certificate Manager is configured for required
FTP client authentication, non-SSL sessions are accepted by the FTP server. However,
non-anonymous FTP users must switch to SSL mode in order to log in to the System i FTP server.
*NO The System i FTP server will only accept non-SSL FTP sessions.
*ONLY
Examples
None
Except for anonymous FTP users, the System i FTP server allows login only from SSL FTP
sessions.
Note:If ALWSSL(*ONLY) is specified and either a prerequisite product required for SSL is not
installed or a valid FTP server certificate is not configured in the Digital Certificate Manager, the
FTP server will not start.
