rsync through ssh tunnel [closed]
I want to rsync to a cluster node to which I usually connect passing through another system:
Say I connect first to
ssh user@bridge
and from there to
ssh user@clusternode
Now I want to rsync from my workstation to clusternode. I do the following:
-
I open a ssh tunnel
ssh -L8000:clusternode:8000 user@bridge
-
I rsync from my workstation to clusternode
rsync -e "ssh -p8000" source user@localhost:destination
and it does not work, I get
ssh_exchange_identification: Connection closed by remote host
Why does it not work? What do I have to do?
I have found a lot of information here:
http://toddharris.net/blog/2005/10/23/rsyncing-through-an-ssh-tunnel/
I think to understand that my problem is the second authentication between the bridge and the destination, so I changed to method 2 that is also not very elegant, but it works. I would like to try method 3, but I don't know how to configure a rsync daemon
Try this one-liner:
rsync -av -e "ssh -A root@proxy ssh" ./src root@target:/dst
Here's what worked for me.
I run a command in the background to tunnel to the remote host:
ssh -N -L 2222:remote.example.com:22 bridge.example.com&
then I rsync to localhost like this:
rsync -auve "ssh -p 2222" . me@localhost:/some/path
You should connect to the port 22 of clusternode, so the tunnel should look like
ssh -L localhost:8000:clusternode:22 user@bridge
