rsync - Nov 2004 - rsync --rsh not reading .ssh/config

I've setup up a single-use key on a remote host to run rsync in server
mode.  I've also setup .ssh/config locally with an IdentityFile to
select the single-use ssh key.

This works on my Debian sid machine:

   rsync --rsh="ssh remove_host" ::

But on another machine that command (and others tried below) do not
access .ssh/config.  The machine is running these:

    $ ssh -v 
    OpenSSH_3.1p1, SSH protocols 1.5/2.0, OpenSSL 0x0090602f

    $ rsync --version
    rsync version 2.4.6  protocol version 24

Again, the problem seems that on this machine .ssh/config is not being
read, but only when ssh is run via rsync.  My guess is this is just a
problem with running the older rsync.  

Is that the case, and is there a workaround other than upgrading
rsync?

Here's some examples of how it's not reading my .ssh/config:


"mysqldump" is the single-use key.  You can see that rsync --rsh=ssh
isn't reading .ssh/config:

$ ls -ltu $HOME/.ssh/config /home/moseley/.ssh/mysqldump
-rw-------    1 moseley  users         668 Nov 11 06:45
/home/moseley/.ssh/mysqldump
-rw-r--r--    1 moseley  users         268 Nov 11 06:45
/home/moseley/.ssh/config

$ rsync -a --rsh="ssh -F $HOME/.ssh/config -i $HOME/.ssh/mysqldump"
remotehost::
unknown host: remotehost

$ ls -ltu $HOME/.ssh/config /home/moseley/.ssh/mysqldump
-rw-------    1 moseley  users         668 Nov 11 06:45
/home/moseley/.ssh/mysqldump
-rw-r--r--    1 moseley  users         268 Nov 11 06:45
/home/moseley/.ssh/config


But if I use ssh directly, you can see .ssh/config is used:

$ ssh remotehost
@RSYNCD: 28
^C

$ ls -ltu $HOME/.ssh/config /home/moseley/.ssh/mysqldump
-rw-------    1 moseley  users         668 Nov 11 09:36
/home/moseley/.ssh/mysqldump
-rw-r--r--    1 moseley  users         268 Nov 11 09:36
/home/moseley/.ssh/config


Other things I've tried:

  $ rsync -e ssh remotehost::
  $ rsync --rsh="ssh -i ~/.ssh/mysqldump" moseley@full_host_name.com::
  $ RSYNC_RSH="ssh -i ~/.ssh/mysqldump" rsync
moseley@full_host_name.com::

Ah, you mean ".ssh/config is being read, but not when ssh is run via
rsync.". Your sentence is a bit confusing :-)

What works a lot better is understanding the rsync syntax.

When you use a double colon "host::", then you're telling ssh to
connect
directly to the rsync daemon running on that host using port 873. In
other words, ssh does not come into the equation, so it's pretty logical
that the .ssh config isn't being read...

Use a single colon, and it should be as you expect.
This is covered in basically the first page of the manual.
