Sure you can also downloading files with curl or wget from remote servers, but files accessible with curl and wget tend to be accessible from the outside world as well, whereas ssh and scp requires authentication or a key, and uses 3DES encryption, making it considerably more secure. Using ssh for remote file downloads like this is most appropriate for secure transfers which require authentication. You can also use scp to download multiple files from a remote server: Warning: Permanently added '192.168.0.4' (ECDSA) to the list of known hosts.Īgain, assuming the connection is approve and the login is successful, the remote file will download from the target server to the localhost. The authenticity of host '192.168.0.4 (192.168.0.4)' can't be established.ĮCDSA key fingerprint is SHA256:31WalRuSLR83HALK83AKJSAkj972JJA878NJHAH3780.Īre you sure you want to continue connecting (yes/no)? yes ![]() This looks like so, and requires a ‘yes’ or ‘no’ answer before the download begins. You can use either scp or rsync to copy folder and files from local to ssh or copy folder and files from ssh to local within in the same or different directory. If you’re new to ssh and testing this out yourself, and if you have never connected to the remote server before, you will be asked to confirm whether or not you wish to actually connect to the remote machine. Scp can also be used to securely place a file on a remote server by adjusting the syntax as well, but we’re focusing on downloading a file rather than uploading files here. Before initiating file transfer using SCP, users must ensure they have read permission for the source file. Scp remote directory/filename.zip" ~/Desktop/ The SSH key is used to validate the remote systems. If the file or path has a space in the name, you can use quotations or escaping on the path like so: Using SCP a client can send (upload) files securely to a remote server or request (download) files. SCP is a method of securely transferring files and entire folders between computers and it is based on the SSH protocol that it’s used with. The basic syntax to use scp (secure copy) for securely downloading remote files is as follows, replacing user, server, path, and target as appropriate:įor example, to download a file to the local desktop named “filename.zip” located in the home directory of remote user “osxdaily” on server IP 192.168.0.45, the syntax would be as follows:Īssuming authentication is correct, the target file will immediately start to download to the target destination, offering a percentage completion, download speed, and elapsed transfer time as the file download proceeds.Īs usual with the command line, it’s important to specify exact syntax. Copying files via SSH uses the SCP (Secure Copy) protocol. So, instead of simple SSH key based auth, EC2 uses PEM file for login. Here scp -i 'key.pem' is because my remote server is on EC2. If you don’t have a remote server to try this with, you can try it out between Mac OS X machines or with localhost if you enable ssh and Remote Login on the Mac beforehand. Example of Local host to the Remote host. This assumes the remote server has ssh active, and if you’re able to ssh into the machine then it will have likely have scp active as well. ![]() ![]() Downloading a File from Remote Server with SSH Secure Copy
