--link-dest not working with rsync daemon?

Alberto Accomazzi Mon, 26 Jan 2004 14:27:37 -0800

I am puzzled as to why I can't get the option --link-dest to work properly. When I use this option when both source and destinations are on a local filesystem the hard-linking of the target against the link-dest directory does work, but when the source is a remote directory (via ssh or rsync server) hard links are not created. I suspect it has something to do with setting the correct timestamp on the files, since the server and client machines have clocks with a large offset, but why would that be the case?

The version of rsync I'm using is:
rsync  version 2.6.0  protocol version 27
Copyright (C) 1996-2004 by Andrew Tridgell and others
<http://rsync.samba.org/>
Capabilities: 64-bit files, socketpairs, hard links, symlinks, batchfiles,
              IPv6, 64-bit system inums, 64-bit internal inums

The distribution is fedora core 1 with kernel 2.4.22-1.2140.nptl. Below you can see the results of my test. Any help is appreciated.

Thanks,
