Rsync-ing from remote to remote

[tim.conway at philips.com]

You're right, in that you can't go remote-to-remote the way rcp can, but 
not about the man page, which explicitely rules out this functionality:

+++++++++++++++++++++++++++++++++++++++++++++++++
     Note that in all cases (other than listing) at least one  of
     the source and destination paths must be local.

SETUP
     See the file README for installation instructions.

SunOS 5.7            Last change: 1 Mar 1999                    2

User Commands                                            rsync(1)
+++++++++++++++++++++++++++++++++++++++++++++++++
You can do what you are attempting, though, fairly easily, as it is plain 
from your example commandline that you are permitted to ssh.  Set up one 
of them to be able to ssh to the other, and 
ssh foo "rsync --rsh=ssh --archive /data/* bar:/data/"
or, if you don't want to let foo rsh to bar,
ssh bar "rsync --rsh=ssh --archive foo:/data/* /data/"
If you don't want either to be able to ssh out, you'll have to use a local 
staging area.

Hi everyone!

I'm trying to do something along those lines:

rsync --rsh=ssh --archive foo:/data/* bar:/data/

Where foo is on the other side of a firewall, bar has no network 
connection
to foo, and the machine I'm executing this on can connect to both of them.

Unfortunately, copying from remote to remote doesn't seem to be possible
with rsync. There's no mention in the Manpage as well, so I guess that
functionality really isn't there.

Do you know some kind of work-around for this? Weird stuff involving 
piping
from one rsync command into another maybe? Or did I miss something in the
Docs?

Thanks in advance for all hints,

-martin
