manpagedescription()

The rsync-ssl script helps you to run an rsync copy to/from an rsync daemon
that requires ssl connections.

If the bf(first) arg is a bf(--type=NAME) option, the script will only use that
particular program to open an ssl connection instead of trying to find an
stunnel or openssl executable via a simple heuristic (assuming that the
bf(RSYNC_SSL_TYPE) environment variable is not set as well -- see below).  This
option must be one of bf(--type=openssl) or bf(--type=stunnel).  The equal sign
is required for this particular option.

All the other options are passed through to the rsync command, so consult the
bf(rsync) manpage for more information on how it works.

Note that the stunnel connection type requires at least version 4 of stunnel,
which should be the case on modern systems.

manpagesection(ENVIRONMENT VARIABLES)

The ssl helper scripts are affected by the following environment variables:

description(

dit(bf(RSYNC_SSL_TYPE)) Specifies the program type that should be used to open
the ssl connection.  It must be one of "openssl" or "stunnel".  The
bf(--type=NAME) option overrides this, if specified.

dit(bf(RSYNC_SSL_PORT)) If specified, the value is the port number that is used
as the default when the user does not specify a port in their rsync command.
When not specified, the default port number is 874.  (Note that older rsync
versions (prior to 3.1.4) did not communicate an overriding port number value
to the helper script.)

dit(bf(RSYNC_SSL_CERT)) If specified, the value is a filename that contains a
certificate to use for the connection.

dit(bf(RSYNC_SSL_CA_CERT)) If specified, the value is a filename that contains
a certificate authority certificate that is used to validate the connection.

dit(bf(RSYNC_SSL_STUNNEL)) Specifies the stunnel executable to run when the
connection type is set to stunnel.  If unspecified, the $PATH is searched first
for "stunnel4" and then for "stunnel".

dit(bf(RSYNC_SSL_OPENSSL)) Specifies the openssl executable to run when the
connection type is set to openssl.  If unspecified, the $PATH is searched for
"openssl".
