scp between 2 hosts from a 3rd host

noir911 · 05-11-2006, 06:38 AM

I am on host X and from here I want to scp files from host Y and Z.

For example,

me@hostX# scp me@hostY:/home/me/file.txt me@hostZ:

This would save me the hassle of connecting to host Y and then scp the file to host Z.

Is there any special switch in scp I can use to achieve this? Or make any changes to sshd_config file?

You don't need any special option, scp can do that anyway.

From the scp man page:

Code:

SYNOPSIS
     scp [-1246BCpqrv] [-c cipher] [-F ssh_config] [-i identity_file]
         [-l limit] [-o ssh_option] [-P port] [-S program]
         [[user@]host1:]file1 [...] [[user@]host2:]file2

Seems like scp can't do it. Here's an example,

Code:

[user1 @ wired ~]$ scp john@linux1:/home/john/test_file john@test:/home/test/
john@linux1's password: <entered> & then the following comes 3 times
Permission denied, please try again.
Permission denied, please try again.
Permission denied (publickey,password,keyboard-interactive).
lost connection

Hmm, according to the man page it should work:

Quote:

Any file name may contain a host and user specification to indicate that
the file is to be copied to/from that host. Copies between two remote
hosts are permitted.

Have you tried it using public keys, so you don't have to enter a password? Either way should work, but it might narrow down the problem.
