Internet TCP port 873 is primarily used by the rsync protocol, a utility for efficiently transferring and synchronizing files across computer systems. This protocol is commonly used in backup and mirroring processes due to its ability to check for differences in files and update only those parts. Examples of software that utilize this port include Grsync and Lsyncd, which are graphical front-ends for rsync. It's important to note that while port 873 is the default, rsync can be configured to use any port.
