scp host1 to host2

[Pradeep kamath]

Hello all,

  scp doesn't seem to do remote copy between 2 hosts ie. scp
host1:<file> host2:<file> doesn't ask for the passphrase when trying to
authenticate to host2. Now if I change my rsa key to have no passphrase
for host2 , I am able to do the remote scp.

Is this a known issue ?
So scp doesnot work if you cannot authenticate without user interaction
to host2?

I am using OpenSSH3.0.2p1

Any pointers will be greatly appreciated.

Thanks in advance.

Regards,
Pradeep.
