Copy files to remote server over ssh


















Hit Enter to leave this blank, then do it again when it asks for confirmation. The next step is to copy the public key file to your remote computer. You can use scp to do this:. In a practical sense, not really. 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. RSA is pretty secure and uses a bit-length by default. If someone has knows your password, your security goes out of the window. 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 combine a password with key files. Follow the steps above, but enter a strong passphrase. This is a really bad idea. If someone finds your password, and you use the same password for all of your accounts, then they now have access to all of those accounts. Similarly, your private key file is also super-secret and important. Have you used SCP in any scripts? Do you use key files instead of passwords?

I configured the same username on both the PC and the server. It is set to pragmalin. Refer to this article in case you would like to setup a similar Debian server as a virtual machine with VirtualBox. Here follows a quick refresher that explains how you can log into your server via SSH. In my case the hostname of the Debian server VM is debianvm. My username on this server is set to pragmalin. This means that I can log into this server via SSH with the command:.

Before diving into the actual file copying via SSH, we should discuss the two commonly used programs for this, namely scp and rsync. The scp program is a secure copy program. So basically a secure and remote version of the cp program that you locally use for copying files. Pretty much all Linux server distributions install the scp program by default, including Debian. Now, if the already installed scp program does all we need then why would we ever need another program for the same task?

The rsync program is labeled as a fast, versatile and remote file-copying tool. But it is not just a plain file-copying tool. The rsync program features build-in synchronization functionality. This means that it only copies a file to the remote server if it is not already present. In contrast, the scp program blatantly overwrites the file. Furthermore, rsync can compress the files during the transfer. In other words, rsync is faster and uses less network bandwidth.

By default rsync does not communicate in a secure way. However, this is not very convenient just for copying files. In this method, you mount the remote directory on your local system. Once mounted, you can copy files between the mounted directory and the local system. You may need to install sshfs on your local system first using your distribution's package manager. Once you have sshfs installed on your system, you can use it to mount the remote directory.

It would be better to create a dedicated directory for the mount point. Once it is mounted, you can copy files into this directory or from this directory as if it is on your local machine itself. I copied the remote. As the last resort, you can use an FTP client for transferring files between remote and local systems. FileZilla is one of the most popular cross-platform FTP client.

You can easily install on your local system. Once you connect, you can see a split window view that shows the local filesystem on the left and the remote filesystem on the right. To transfer the file, drag and drop files from left to right or right to left.
