I have a raspberry pi zero v1 and a raspberry pi model 3 B+. The second one has some testing files i want to transfer to the first one.

Right now i’m ssh’ed into both raspberry pi’s (I’ll call them rp’s for short). Rp Zero v1 doesn’t have Wi-Fi capabilities so I’m connected to the internet through the USB port in my PC, so i have accessed it via:

SSH [email protected]

And I’ve accessed the second one via:

SSH pi@<ip address>

Normally i use:

Scp <file> <path in original directory> <user I want to transfer to>:<path I want to transfer to>

To copy files from my pc to an rp, but I’m not sure what the user i want to transfer to is. I have tried

Scp <file> <original path> [email protected]:<destination path>

And

Scp <file> <original path> pi@<ip address>:<destination path>

Where <ip address> is what I obtained from running the command:

Hostname -I

On the rp zero v1.

Neither of these work and I think I may be missing some conceptual understanding of how the rp zero v1 is connected to the internet. I would appreciate some guidance to understand that as well as how to transfer files without having to first transfer something to my computer.

  • Scp usage: scp [options] [local path] [remote path] The local path is just a normal path, don't use something like me@here:/foobar. The remote path requires the remote user name (same as their login) and the hostname or IP: me@there:/absolute/path. If it does not work, scp -v will output some debugging information, scp -vv more. Edit it in the output from the latter with the exact command you are using and be aware of man scp.

  • You wrote "Neither of these work". How exactly does it not work? Do you get an error message? Then, please, copy&paste the exact command and the error message to your question. Or do you get a result different from what you expect? Then show/describe the actual and expected result in your question. edit your question to provide these details. Note that the ssh and scp commands are normally written with lowercase letters. On Windows it may be case-insensitive, but not on Linux.

Instead of using ssh, use sftp. Here's how it looks from the terminal:

pi@raspberrypi3b:~ $ sftp [email protected]
The authenticity of host 'raspberrypi0w.local (192.168.1.51)' can't be established.
ECDSA key fingerprint is SHA256:AuR********************w9YDcZ0bijTO17zbeqvM.
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes
Warning: Permanently added 'raspberrypi0w.local,192.168.1.51' (ECDSA) to the list of known hosts.

sftp>

Once you get the sftp> prompt, type the ? character to get a list of the commands & brief description of their meaning. The get & put commands perform the actual file transfers. See man sftp for more details; exit closes the connection.

And if you want to use SSH key authentication instead of passwords, follow this guide to generate your public-private key pair & transfer the public key to the pi zero.

If you are using internet connection sharing on the PC you can't.

You can turn ICS off (which will stop internet access) but then can ssh.

Incidentally ftp is a far easier way to transfer files and most PC have ftp clients.
