openssh unix dev - Jun 2000 - Remote -> remote scp not working

Hello,

Using openssh 2.1.1p1 I have tried to use scp to copy a file from one remote
system directly to another remote system - e.g. 'scp -i ./ecp eros:jhf
alice:jhf', so the file jhf is copied from the remote system eros to the
remote system alice via an intermidate system (the one where the command is
issued from). The key is in the file ecp.

Using protocol 1 it doesn't seem to work. I can issue:
   scp -i ./ecp eros:jhf .
   scp -i ./ecp jhf alice:jhf

and these work fine. However, combining the two just gives me 'permission
denied'. Using -v doesn't seem to show much more:

Executing: exec /usr/local/bin/ssh -v -x -o'FallBackToRsh no' -n eros
scp -v
jhf 'alice:jhf'

The 'config' file mentioned above simply states:

I have gotten around this by copying the file directly from one system to
the other, but according to the man page a remote-remote copy should work.

Thanks,

John.

'permission

	% scp bela:/bsd nohow:/tmp

actually executes:

	% ssh bela 'scp /bsd nohow:/tmp'

so authentication from host 'bela' to 'nohow'
has to work without user interaction.
the localhost does not authenticate you to both
remote hosts (only to bela).

note that the name 'nohow' is interpreted on host 'bela'.
