rsync - Sep 2004 - Rsync param parsing using --rsh broken? (was: no subject)

Reposting this with a subject line :-)

Hi,

I'm trying to get rsync over OpenSSH/Cygwin working. I started with a
command
 like this (which fails):

$ rsync -v -v -v --recursive --rsh="ssh -i
/home/ul081b/mpdm-keys/rsa-mpdm01mpdm@mpdm-w2k3"  MPDM-W2K3::MPDM .
opening connection using ssh -i /home/ul081b/mpdm-keys/rsa-mpdm01 mpdm@mpdm-w2k3
MPDM-W2K3 rsync --server --daemon .
bash: line 1: MPDM-W2K3: command not found
rsync: connection unexpectedly closed (0 bytes read so far)
rsync error: error in rsync protocol data stream (code 12) at
 /home/lapo/package/tmp/rsync-2.6.2/io.c(342) _exit_cleanup(code=12,
 file=/home/lapo/package/tmp/rsync-2.6.2/io.c, line=342): about to call
 exit(12)

The above example should work, if I'm reading the docs correctly.

After hours of getting nowhere, I tried this (which worked, but it doesn't
 look to me that this is the way the docs say to do it) (the only difference
 is I left out the hostname adjacent to the module):

$ rsync -v -v -v --recursive --rsh="ssh -i
/home/ul081b/mpdm-keys/rsa-mpdm01 mpdm@mpdm-w2k3"  ::MPDM .
opening connection using ssh -i /home/ul081b/mpdm-keys/rsa-mpdm01 mpdm@mpdm-w2k3
rsync --server --daemon .

So, what's going on here? Am I missing something in the docs, is something
 wrong in the docs or is this a bug?

Thanks,

That line must have contained a space prior to the mpdm@mpdm-w2k3 part
or it wouldn't have failed as it did.  That is specifying a
user+hostname to ssh, and rsync always supplies the hostname, so
obviously that conflicts.  If you want to specify an ssh user when using
a daemon-over-ssh command, use the -l option to ssh:

rsync -vrt --rsh="ssh -i /home/ul081b/mpdm-keys/rsa-mpdm01 -l mpdm"
mpdm-w2k3::MPDM .

Wayne, 

Thanks for the reply. I disagree with your analysis, however. Here is a test
with your suggestion (notice that the command not found complains about the
uppercase MPDM-W2K3). Also, the logs show that the ssh connection was
established, so the entire quoted param for --rsh is likely correct (it works
with both the @ and the -l):

$ rsync -v -v -v --recursive --rsh="ssh -i
/home/ul081b/mpdm-keys/rsa-mpdm01 -l mpdm mpdm-w2k3"  MPDM-W2K3::MPDM .
opening connection using ssh -i /home/ul081b/mpdm-keys/rsa-mpdm01 -l mpdm
mpdm-w2k3 MPDM-W2K3 rsync --server --daemon .
bash: line 1: MPDM-W2K3: command not found
rsync: connection unexpectedly closed (0 bytes read so far)

OK, now I see. I did not notice the --rsh param is not the exact command that
would invoke ssh by itself.  Thanks for your help.
