Encounter this error when trying to transfer file from local to remote machine. Both of this machine running on Redhat Linux. Can someone help what does this error means? And what would be the solution for it? Please advice. Thanks. rsync local version:3.0.6 version 30 rsync remote version:2.6.3version 28 rsync error: requested action not supported (code 4) at clientserver.c(473) rsync: connection unexpectedly closed (4 bytes received so far) [receiver] rsync error: error in rsync protocol data stream (code 12) at io.c(600) [receiver=3.0.6]
You don't show what command line you're using. The clue is probably in the message "requested action not supported", you're talking to a pretty ancient version of rsync which probably doesn't support some of the options you're requiring rsync to perform.
It is best to ask questions about issues you're having on the mailing list: https://rsync.samba.org/lists.html
