| 239 | This package comes with two types of units: A service file and a
|
|---|
| 240 | socket file. The service file will start rsync daemon once at boot
|
|---|
| 241 | and it will keep running until the system shuts down. The socket file
|
|---|
| 242 | will make systemd listen on rsync port (Default 873, needs to be
|
|---|
| 243 | edited for anything else) and will start rsync daemon when something
|
|---|
| 244 | tries to connect to that port and stop the daemon when the connection
|
|---|
| 245 | is terminated. This is called socket activation and is analogous to
|
