I am trying to configure rsync to run as a daemon. I created an rsyncd.conf file but rsync does not start. I get the following error:
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at /SourceCache/rsync/rsync-8/rsync/io.c(140)

Any ideas?

How are you invoking rsync? Are you using the --daemon flag? Have you set it up as either a startup item, or configured inetd to invoke it? Are you sure you need it to run as a daemon? In most cases, it's not even necessary to set up a daemon (although this may have performance advantages if invoked often).

From man rsync:

Code:
       --daemon
              This  tells  rsync  that  it is to run as a daemon.
              The daemon may be accessed using  the  host::module
              or rsync://host/module/ syntax.

              If  standard  input  is  a  socket  then rsync will
              assume that it is being run via inetd, otherwise it
              will  detach from the current terminal and become a
              background daemon.  The daemon will read the config
              file  (/etc/rsyncd.conf)  on each connect made by a
              client and respond to  requests  accordingly.   See
              the rsyncd.conf(5) man page for more details.

I am invoking rsync with the command 'rsync localhost::' and I get the error messages mentioned above.

As i understand it, the command you're giving it is telling rsync to connect to a remote rsync server (in this case, on your own box), not start a local server. And since you've specified no files to transfer, it would close down right away, so the result you're getting seems appropriate under the circumstances.

If you want to start up a server, you need to use something like "rsync --daemon". At least that's my understanding; i could be wrong.

I got things working properly when I switched to ssh rather than rsh.

Thanks.
