I am using rsync over ssh (set RSYNC_RSH=ssh) to copy a bunch of files
between 2 linux boxes [RH 8.0 client and RH 9.0 server]. Both ends are
running rsync 2.5.6, after compiling from sources.

I notice that rsync copies *all* the files even if nothing changes.
The way I can tell is that the time stamp changes for all the files on
the client side.

The command I used was:

export RSYNC_RSH=ssh
rsync -rv root@colby:/var/tmp/rgy .
