SCP to a server where I have SSH permission

Question

I am trying to SCP a file I downloaded using this command:

scp -v agenadinik@slabrams-desktop:/home/agenadinik/Downloads/agraph-4.2-linuxamd64.64.tar.gz agenadin@uc3-dev:/udfr/agraph-4.2-linuxamd64.64.tar.gz

The output is this:

Executing: /usr/bin/ssh '-v' '-x' '-oClearAllForwardings yes' '-n' '-l' 'agenadinik' 'slabrams-desktop' 'scp -v' '/home/agenadinik/Downloads/agraph-4.2-linuxamd64.64.tar.gz' 'agenadin@uc3-dev:/udfr/agraph-4.2-linuxamd64.64.tar.gz'

Any ideas why it wouldn't work? Also, the only reason I am doing that is because I am not sure how to download that file from the ssh command prompt directly. Is there a way to just download that file from the shell of Putty's ssh client? What are my options here? :)

Thanks you!

I'm not sure where putty (the windows ssh client) comes into play... It looks like you're copying between two linux (ubuntu) servers.

Does it work if you login directly to one of the servers, so that you aren't remotely copying between two remote servers? E.g., instead of:

From: 
  Host: agenadinik@slabrams-desktop
  File: /home/agenadinik/Downloads/agraph-4.2-linuxamd64.64.tar.gz
To:
  Host: agenadin@uc3-dev
  File: /udfr/agraph-4.2-linuxamd64.64.tar.gz

...first login to agenadinik@slabrams-desktop, and then run:

cd /home/agenadinik/Downloads/
scp agraph-4.2-linuxamd64.64.tar.gz agenadin@uc3-dev:/udfr/

Or, vice-versa; login to agenadin@uc3-dev and run:

cd /udfr
scp agraph-4.2-linuxamd64.64.tar.gz agenadinik@slabrams-desktop:/home/agenadinik/Downloads/

Breaking down the command in this way might help debug & track down permission/connection issues....

Copying to a windows pc from the remote linux server (executing the copy from teh remote linux box -- assuming you're using putty on windows to ssh into a remote unix/linux box) won't work unless you have an sshd server running on windows (e.g., cygwin sshd). If you have that, then you can login to the remote linux host, and, using your windows hostname or ip address (and, it helps to avoid windows path issues and just copy to your windows $HOME),

linux> scp file.tar.gz  windows_user@windows_host:~/

...But typically people don't have sshd running on windows, and it isn't always that simple to set up.

Edit: just to clarify: copying to windows & running the scp/sftp commands on windows (e.g., using putty's psftp or pscp) is trivial, as it only remotely logs into the linux server & copies the file locally.

Answer 2

PuTTY has an SCP client & an SFTP client, both on the download page. Or you could grab FileZilla.

As for the issue, can slabrams-desktop resolve uc3-dev and vice-versa? Can they connect to each other?
