SFTP is similar to FTP (File Transfer Protocol), but it uses SSH to encrypt the data transfer. SFTP (Secure File Transfer Protocol)Īnother way to transfer files over SSH is through SFTP (Secure File Transfer Protocol). SCP is a great tool for quickly copying a single file between machines, but if you need to transfer multiple files or entire directories, it can be more efficient to use SFTP. To copy a file from a local machine to a remote machine, use the following syntax − $ scp host]:įor example, to copy a file named "file.txt" from the local machine to the remote machine with IP address "192.168.1.100" and save it in the home directory of the user "john", use the following command − $ scp file.txt copy a file from a remote machine to a local machine, use the following syntax − $ scp host]: įor example, to copy a file named "file.txt" from the remote machine with IP address "192.168.1.100" and save it in the home directory of the local machine, use the following command − $ scp ~ The syntax for SCP is similar to the regular cp command, but with the addition of the “-scp” option. SCP (Secure Copy) is a command-line utility that allows you to securely transfer files between machines over SSH. Once SSH is installed, you can start the SSH service and configure it for remote access. If not, you can install it using your distribution's package manager. If the output shows the version of SSH, it is already installed. You can check if SSH is already installed on your machine by running the following command − $ ssh -v It creates an encrypted tunnel between the two machines, protecting your data from eavesdropping and tampering. SSH is a secure communication protocol that allows you to remotely access and manage your Linux machines. Setting up SSHīefore you can transfer files over SSH, you need to set up SSH on both the source and destination machines. In this article, we will explore different ways to transfer files over SSH and demonstrate the process with examples and commands. SSH ( Secure Shell) is a protocol that allows you to securely transfer files between machines, as well as remotely access and manage them. We can then modify the previous command to use the new variable.Transferring files between Linux machines over SSH is a common task for system administrators and developers. We can work around this if we have SSH forward an environment variable with the password.įor example we can choose an environment variable that we know gets forwarded based on the configuration in /etc/ssh/sshd_config and set this in ~/.ssh/config. One problem with this approach is that the root password will show in the process list on the docker host. "sudo -p '' -S - docker exec tar cf -C " \ docker exec will launch tar that archives the file and opens a pipe to SSH that forwards the pipe to tar on the local host. We pipe the password to SSH that forwards the pipe to sudo. With the above working the next command will transfer a single file from the docker container to the localhost. The following command should return the hostname of the docker container.
