As examples, we move an Azure configuration file up to a Linux VM and pull down a log file directory, both using SCP and SSH keys. SSH key pair authentication. SCP uses SSH for the transport layer. Dynwalls. SSH handles the authentication on the destination host, and it moves the file in an encrypted tunnel provided by default with SSH. Apr 22, 2020.
This document will help you connect to make real remote connection to your Mac server using SSH protocol.
SSH (“secure shell”) is an application-level network protocol designed for secure remote access to UNIX systems.
How to Activate SSH Connection in macOS
Follow the instructions in this article to enable remote control of SSH for macOS server:
- Open the “System Preferences”;
- Choose “Sharing”;
- In the left column of the service, enable the “Remote Login” option.
Firewall
If the firewall is enabled (by default), you may need to restart the firewall to allow SSH passing through port 22:
- Open the “System Preferences” -> “Security and Privacy”;
- Restart the Firewall;
- Unlock Access with “Lock” icon;
- Turn it “Off” and put it “On” again;
- If you cannot log in, restart the firewall or restart the computer.

Connect to SSH Server
UNIX-based operating systems, such as macOS and Linux, include a built-in SSH command that works almost the same everywhere. We need to know the IP address of the SSH server and the password for the user or root.
To connect to an SSH server, open a terminal window on a Mac:
- Open “Terminal”;
- To connect to the SSH server, enter the following command in the terminal, replacing the username on your’s SSH server login and use the hostname or IP address of the server to which you are connecting:
- A message will appear on the screen to confirm your identity, you must enter a password and the system will greet you and inform you of a successful login.
Conclusion
SSH is effective in that it encrypts all information transmitted over the network, in contrast to the telnet protocol. Basically, it is needed to remotely manage user data on the server, run service commands, work in console mode with databases. This does not end the possibilities of this tool.
SSH is the most secure protocol for accessing remote servers. It provides the highest level of end to end data security over communication channels. The SCP (Secure Copy) command uses the SSH protocol for copying files between remote and local servers.
The remote server must have running SSH server. This tutorial will help you to understand download and upload file over SSH protocol.
Download file using SSH
This will connect to example.com server with user “username” and copy the /backup/file.zip file to local system directory /local/dir. To use theis command replace the values as per your environment.
If the SSH is running on non-standard port, You can specify the port using
-P
option with SCP command.If your remote server required the private key to connect server, You can use
-i
followed by private key file path to connect your server using the SCP command. This can be helpful for AWS servers.Upload file using SSH
Ssh Download File Command
You can also upload files to the remote server using SSH protocol using SCP command. Use the following example command for uploading files to SSH server.
Download Files From Ssh Linux
Similarity you can use -P switch to define port of the SSH server and -i to define private key for the user authentication. Native instruments komplete start free.
