How to transfer file from MacOS to Ubuntu Server?

Question

I tried the following command using my Mac Terminal

scp -rp /path/file user@SERVER_IP:/path/destination/folder

It gives me following error:

user@SERVER_IP: Permission denied (public key).
lost connection

Is there any ports that i am missing to open?

I am using GC Compute Engine. I am able to connect using SSH button on VM Instance on GC — Maqsud Inamdar, Mar 12 '20 at 07:57
"Is there any ports that i am missing to open?" no you are missing a public key. Please read up on how security works in regards to scp. — Rinzwind, Mar 12 '20 at 08:31
See for instance https://askubuntu.com/questions/803908/how-do-i-add-an-ssh-key-to-a-google-compute-cloud-vps-instance But be careful. Doing it incorrectly can lock you out. — Rinzwind, Mar 12 '20 at 08:33

Does this answer your question? Filezilla or WinSCP alternative for Ubuntu — pa4080, Mar 12 '20 at 13:50

Normally, scp asks for a password. To avoid this, or to automate file copying in scripts, public key authentication is usually used. The basic idea is to create a key pair on the client and copy the public key to the server into an authorized keys file.

No you are not missing any ports.

Here is an answer:

You need to check if the remote directory(Where you are posting) has permissions for other users.

If not, run: sudo chmod 777 [remote directory]

This should work!
