   According to the man page it's TCP port 873.   
      
   Anyway I think it makes much more sense than dealing with all the   
   complexities, fragilities, and inefficiencies of encryption just   
   to do transfers over a private LAN. LDO evidently concludes the   
   opposite.   
      
   Here's an example of a public rsync 'site'. This command lists   
   syncable directories and their descriptions:   
      
   rsync rsync://mirrors.dotsrc.org   
      
   This page also describes how it can use TLS encryption using a   
   script for OpenSSL "s_client", but that's not part of the base   
   protocol:
