rsync-ssl - a helper script for connecting to an ssl rsync daemon
-# SYNOPSIS
+## SYNOPSIS
```
rsync-ssl [--type=SSL_TYPE] RSYNC_ARGS
```
-# DESCRIPTION
+The online version of this manpage (that includes cross-linking of topics)
+is available at <https://download.samba.org/pub/rsync/rsync-ssl.1>.
+
+## DESCRIPTION
The rsync-ssl script helps you to run an rsync copy to/from an rsync daemon
that requires ssl connections.
-# OPTIONS
+The script requires that you specify an rsync-daemon arg in the style of either
+`hostname::` (with 2 colons) or `rsync://hostname/`. The default port used for
+connecting is 874 (one higher than the normal 873) unless overridden in the
+environment. You can specify an overriding port via `--port` or by including
+it in the normal spot in the URL format, though both of those require your
+rsync version to be at least 3.2.0.
+
+## OPTIONS
If the **first** arg is a `--type=SSL_TYPE` option, the script will only use
that particular program to open an ssl connection instead of trying to find an
required for this particular option.
All the other options are passed through to the rsync command, so consult the
-**rsync** manpage for more information on how it works.

-# ENVIRONMENT VARIABLES
+## ENVIRONMENT VARIABLES
The ssl helper scripts are affected by the following environment variables:
-0. `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
- `--type=SSL_TYPE` option overrides this, when specified.
-0. `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 3.2.0) did not communicate an overriding port number
- value to the helper script.)
-0. `RSYNC_SSL_CERT` If specified, the value is a filename that contains a
+0. `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 `--type=SSL_TYPE` option
+ overrides this, when specified.
+
+0. `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 3.2.0) did not communicate an overriding port number value to the
+ helper script.)
+
+0. `RSYNC_SSL_CERT`
+
+ If specified, the value is a filename that contains a certificate to use
+ for the connection.
+
+0. `RSYNC_SSL_KEY`
+
+ If specified, the value is a filename that contains a key for the provided
certificate to use for the connection.
-0. `RSYNC_SSL_CA_CERT` If specified, the value is a filename that contains a
- certificate authority certificate that is used to validate the connection.
-0. `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".
-0. `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".
-# EXAMPLES
+0. `RSYNC_SSL_CA_CERT`
+
+ If specified, the value is a filename that contains a certificate authority
+ certificate that is used to validate the connection.
+
+0. `RSYNC_SSL_OPENSSL`
-> rsync-ssl -aiv example.com::src/ dest
+ Specifies the openssl executable to run when the connection type is set to
+ openssl. If unspecified, the $PATH is searched for "openssl".
-> rsync-ssl --type=openssl -aiv example.com::src/ dest
+0. `RSYNC_SSL_GNUTLS`
-# SEE ALSO
+ Specifies the gnutls-cli executable to run when the connection type is set
+ to gnutls. If unspecified, the $PATH is searched for "gnutls-cli".
-**rsync**(1), **rsyncd.conf**(5)
+0. `RSYNC_SSL_STUNNEL`
-# CAVEATS
+ 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".
+
+## EXAMPLES
+
+> rsync-ssl -aiv example.com::mod/ dest
+
+> rsync-ssl --type=openssl -aiv example.com::mod/ dest
+
+> rsync-ssl -aiv --port 9874 example.com::mod/ dest
+
+> rsync-ssl -aiv rsync://example.com:9874/mod/ dest
+
+## THE SERVER SIDE
+
+For help setting up an SSL/TLS supporting rsync, see the [instructions in
+rsyncd.conf](rsyncd.conf.5#SSL_TLS_Daemon_Setup).

+## SEE ALSO
+
+[**rsync**(1)](rsync.1), [**rsyncd.conf**(5)](rsyncd.conf.5)
+
+## CAVEATS
Note that using an stunnel connection requires at least version 4 of stunnel,
which should be the case on modern systems. Also, it does not verify a
connection without any cert validation unless you have specified the
certificate environment options.
-# BUGS
+This script also supports a `--type=gnutls` option, but at the time of this
+release the gnutls-cli command was dropping output, making it unusable. If
+that bug has been fixed in your version, feel free to put gnutls into an
+exported RSYNC_SSL_TYPE environment variable to make its use the default.
