Indeed, I want to: * to start rsync session A->C * cannot establish ssh session A->C (firewall) * but can establish ssh session A->B and B->C
I think I understand the ssh hop. If I'm correct. I make a script file ssh-b that I subsequently invoke in the rsync command (./ssh-b).
Unfortunately I still have a question concerning the ssh-b script. I have put:
#!/bin/sh exec ssh [EMAIL PROTECTED] ssh "$@"
What stands the "$@" for?
When I run the ssh-b script and enter my password for host-B I get the --help printout on my screen?
I assume I have to write something like:
#!/bin/sh exec ssh [EMAIL PROTECTED] ssh [EMAIL PROTECTED]
But then I get the error: Pseudo terminal will not be allocated becausestdin is not a terminal. Permission denied.
Thanx for your help so far. It already helped a lot.

I tried to connect the tunnel with another port number. When I use port number 22 instead of 873 I can telnet to C from B.
When I telnet I get "SSH-1.99-OpenSSH_3.9p1."
Subsequently I ran: ssh -v -L 22:C-computer:22 [EMAIL PROTECTED]
When I run now the rsync command: rsync -v /cygdrive/d/folder/ 127.0.0.1::cygdrive/folder I get the error: "failed to connect to 127.0.0.1. Connection refused."
When I run:
rsync -v --port=22 /cygdrive/d/folder/ 127.0.0.1::cygdrive/folder
I get the error "server sent SSH-1.99-OpenSSH_3.9p1 rather than greeting"
I assume it is a problem associated with the telnet command. Can anyone help?
As I understand: * you want to start rsync session A->C * you can not establish ssh session A->C (firewall) * you can establish ssh session A->B and B->C
Try to use "extra ssh hop" script:
1) Create ssh-b script on host A:
#!/bin/sh
exec ssh _host_B_ ssh "$@"
2) Use the above sctipt in rsync session rsync -e ./ssh-b ....
