Open your terminal and go to the directory that holds to previously downloaded WordPress archive. tar cf - dir ssh remotehost 'tar xfC - /path/on/remote'. Let’s start out with copying just a single file to the server via SSH. To extract the archive in a different directory on the remote host, use. For example, using tar: tar cf - dir ssh remotehost 'tar xf -'. If someone has your private key file, then security is lost to any computer that has the matching pubic key, but they need access to your computer to get it. You can use cpio or tar to create an archive as a stream on standard output, pipe that to ssh and extract the stream on the remote host. If someone has knows your password, your security goes out of the window. You will connect the the remote system and your prompt will change to an SFTP prompt. Now we can establish an SFTP session by issuing the following command: sftp sammy yourserveriporremotehostname. Transferring files to the remote system works the same way, but with a put command: put localFile Output Uploading localFile to /home/demouser/localFile localFile 100 7607 7.4KB/s 00:00 The same flags that work with get apply to put. It’s actually pretty similar in theory to using your password. If that works, exit back out by typing: exit. RSA is pretty secure and uses a 2048 bit-length by default. The SCP utility comes by default with SSH, it is used for transferring files between remote computers. One solution would be to suspend the ssh session on the local machine, perform the copy on the local machine and then resume your ssh session where you left off. This private key ONLY matches with that ONE public key, and the connection needs to be started from the computer that has the private key. In interactive SSH session mode, we enter commands at the prompt, but all of them execute on the remote machine: hostname personal.local ssh hostname Copy Here, we use hostname to output the current machine’s hostname. If you need to copy files from your local machine to a remote server using SSH protocol, you can do it by using the SCP command on Linux Ubuntu, Linux Mint and Debian as others. The private key that’s generated is stored on the computer you’re using, and it is never transferred, not even to be verified. RELATED: What Is a PEM File and How Do You Use It? Security Considerations This means that if you wanted to add another public key for your account on this server, you would copy the contents of the second id_rsa.pub file into a new line on the existing authorized_keys2 file. Subsequent public keys can be appended to this file, much like the ~/.ssh/known_hosts file.
