I can successfully log in to mycloud as root or another user I added. I need to use the scp command to send an image to my folder. It keeps asking for the password and saying its wrong when I know it's right. Ben@192.168.1.20 is my local computer but i have to identify the source or it will say "no such file or directory". Also, Ben can be capital or lowercase it does not make a difference.

WDMyCloud:~# scp -v Ben@192.168.1.20:/Users/***/Desktop/Apple.jpg root@192.168.1.4:/DataVolume/shares/Ben
Executing: /usr/bin/ssh '-x' '-oClearAllForwardings=yes' '-n' '-v' '-l' 'Ben' '--' '192.168.1.20' 'scp -v' '/Users/Ben/Desktop/Apple.jpg' 'root@192.168.1.4:/DataVolume/shares/Ben'

  • Could you un-hide the IP addresses here? 192.168.1.* addresses aren't security sensitive in a home network, you've only hidden half of them anyway, and it makes it way more confusing to follow what's going on. – Jander Jul 18 '15 at 18:10
  • Thanks. So if I'm reading this right, you're logged into your WDMyCloud (.1.4), and you want the WDMyCloud to pull a file from your local computer (.1.20) onto its own hard drive? – Jander Jul 18 '15 at 19:23
  • yes thats right – Ben333 Jul 18 '15 at 20:03
  • I seem to always get the error Permission denied (publickey,password). – Ben333 Jul 18 '15 at 20:32

The short answer is that scp does interesting things when you give it two IP addresses to work with. If your source or destination is the machine running the scp command, then one of your paths should be local. If you're on the MyCloud, try this:

WDMyCloud:~# scp Ben@192.168.1.20:/Users/***/Desktop/Apple.jpg /DataVolume/shares/Ben

Or if you're on your local machine:

LocalComputer:~# scp /Users/***/Desktop/Apple.jpg root@192.168.1.4:/DataVolume/shares/Ben

If you're curious about what's happening in this case, though, you can look at the "Executing:" output from your scp -v.

Executing: /usr/bin/ssh '-x' '-oClearAllForwardings=yes' '-n' '-v' '-l' 'Ben' '--' '192.168.1.20' 'scp -v' '/Users/Ben/Desktop/Apple.jpg' 'root@192.168.1.4:/DataVolume/shares/Ben'

One interesting thing about ssh is that you can use it to run a single command immediately instead of an interactive shell. What is happening here is that instead of copying the file itself, your scp is asking 192.168.1.20 to handle the copying. It's as if you ran the following:

WDMyCloud:~# ssh Ben@192.168.1.20
Password: [password to Ben@LocalComputer goes here]
LocalComputer:~$ scp /Users/***/Desktop/Apple.jpg root@192.168.1.4:/DataVolume/shares/Ben
Password: [password to root@WDMyCloud goes here]
LocalComputer:~$ exit

Why does scp do this? It's an efficiency measure that makes a lot more sense for the following case:

LocalComputer:~$ scp Ben@192.168.1.99:/path/to/Apple.jpg root@192.168.1.4:/DataVolume/shares/Ben

In this case, the file is on one remote computer and you want to copy it onto another remote computer. If your local computer did the copying, it would be tied up all throughout the copy process, ferrying bits from one remote computer to the other. It's a lot more efficient to have one of the remotes connect directly to the other.

  • WDMyCloud:~# scp Ben@192.168.1.20:/Users/***/Desktop/Apple.jpg /DataVolume/shares/Ben Worked!!!!! I totally get it. I was on WDMyCloud so when I entered the destination directory, I didnt need ben@192.168.1.4 because that is itself (local). Instead of trying to ask my laptop to put a file on the drive when I was logged into the drive via ssh, I needed to ask the drive to pull the file from my laptop. Thanks so much for the help Jander!! – Ben333 Jul 19 '15 at 14:43
