If you're not sure whether your Linux machine is running SSH, then run this command on the Linux machine: $ sudo systemctl enable -now sshd The pscp command uses the OpenSSH protocol, so your Linux computer must be running the OpenSSH server software, and its firewall must allow SSH traffic. If you're not sure which is which, you can try each one in succession until you get the right one (and then write it down somewhere!)Īlternately, you can look in the settings of your router, which lists all addresses assigned over DHCP. On your system, the IP address is likely to be different. In all cases, 127.0.0.1 is a loopback address that the computer uses only to talk to itself, so in this example the correct address is 192.168.1.23. Assuming it's a computer on your same network, and that you're not running a DNS server to resolve computer names, you can find the destination IP address using the ip command on the Linux machine: $ ip addr show | grep 'inet ' Type pscp –version to confirm that your computer can find the command.īefore you can make the transfer, you must know the IP address or fully-qualified domain name of the destination computer. Open Powershell on your Windows computer using the search bar in the Windows taskbar (type 'powershell` into the search bar.) If you haven't set a PATH variable for yourself, you can alternately move pscp.exe to the folder holding the files you're going to transfer. Move pscp.exe to a folder in your PATH (for example, Desktop\App if you followed the PATH tutorial here on ). PSCP (PuTTY Secure Copy Protocol) is a command-line tool for transferring files and folders from a Windows computer to a Linux computer. If you're unfamiliar with that process, read how to set a PATH on Windows. Knowing how to set your command path in Windows makes it easier to use a handy utility like PSCP. Welcome to the communityĪre you looking for a way to quickly transfer files from your Windows computer to your Linux computer and back again? The open source PSCP utility makes it easy to transfer files and folders, and of course it's open source.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. If someone has knows your password, your security goes out of the window. It’s actually pretty similar in theory to using your password. RSA is pretty secure and uses a 2048 bit-length by default. 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. 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.
