-1

I want to transfer files from one server to another.

scp -r user@11.11.11.22:/home/filename.php user@server.com:/home/scripts

When I run this command I received an answer that I need to put password for the server.com. But I'm not using the password, I'm using a key. how I can insert the key instead of the pass?

    Is the key on the local machine? I think unless you use -3, your local key doesn't matter. – Kamil Maciorowski Feb 18 '20 at 18:23
  • The issue is you are using a third machine — your local machine — to copy files from 11.11.11.22 to server.com. I am sure if you login directly to 11.11.11.22 you can then run this command fine: scp -r /home/filename.php user@server.com:/home/scripts. – Giacomo1968 Feb 18 '20 at 18:25
  • But I logged on via putty to the server from which I want to send the files – ririririri Feb 18 '20 at 18:26
  • @ririririri If you are logged directly into 11.11.11.22 then your command doesn’t need the [user]@[hostname] stuff. It can just be scp -r /home/filename.php user@server.com:/home/scripts. In fact, drop the -r — since you are just copying one file — and run it like this: scp /home/filename.php user@server.com:/home/scripts. – Giacomo1968 Feb 18 '20 at 18:28

The issue might be that you are using a third machine — your local machine — to copy files from 11.11.11.22 to server.com. I am sure if you login directly to 11.11.11.22 you can then run this command fine:

 scp -r /home/filename.php user@server.com:/home/scripts

But if you are actually logged directly into 11.11.11.22 then your command doesn’t need the [user]@[hostname] stuff. It can just be:

scp -r /home/filename.php user@server.com:/home/scripts

In fact, drop the -r — since you are just copying one file — and run it like this:

scp /home/filename.php user@server.com:/home/scripts

Just be sure you use the -A option when SSHing into 11.11.11.22. As the SSH man page states:

“Enables forwarding of the authentication agent connection. This can also be specified on a per-host basis in a configuration file.”

Meaning your key from your local machine is passed along during the SSH session. So you initially login to 11.11.11.22 like this:

 ssh -A user@11.11.11.22

You can then cleanly login to server.com like this:

ssh user@server.com

Which then means this SCP command should work without prompting for a password:

scp -r /home/filename.php user@server.com:/home/scripts

  • It still asks me to enter the password. Can it be that the server needs to give me permission to send files? – ririririri Feb 18 '20 at 18:31
  • @ririririri “Can it be that the server needs to give me permission to send files?” As long as you can login, you should be good. When you are logged into 11.11.11.22 what happens when you just run ssh user@server.com and login to that other server? – Giacomo1968 Feb 18 '20 at 18:33
  • when i type ssh user@server.com it again asks me for password, but i dont have password, im using key to login – ririririri Feb 18 '20 at 18:34
  • @ririririri So when you initially SSH into 11.11.11.22, I recommend using ssh -A user@11.11.11.22. And then when you are logged in, do ssh user@server.com and you should be able to login. That -A “Enables forwarding of the authentication agent connection. This can also be specified on a per-host basis in a configuration file.” Meaning it passes your keys from your local host to that connection. Meaning — if you use ssh -A — that when you are logged into 11.11.11.22, the SSH agent will be aware of your key and you can then cleanly do an ssh user@server.com and log yourself in. – Giacomo1968 Feb 18 '20 at 18:41
  • I did it, but still asks me for password. – ririririri Feb 18 '20 at 18:47
  • @ririririri Then there are aspects of this setup you are not explaining well. Please look at the output of ssh -A -v user@11.11.11.22 as well as the output of ssh -v user@server.com to see if that verbose output gives you any clues. – Giacomo1968 Feb 18 '20 at 18:48

  • @ririririri If you genuinely want help, you need to provide these details and specifics to your question. The reality is you are missing a lot of details in your question. Without those details, nobody here can help you. – Giacomo1968 Feb 18 '20 at 20:15
