![]() Finally, if you’re looking for a penetration test, training for your organization, or just have general security questions please Contact Us. If you’re interested in security fundamentals, we have a Professionally Evil Fundamentals Youtube channel that covers a variety of technology topics.

Otherwise, the command structure is exactly the same, scp. The main difference here is that the source of the files or folders are now in a remote location, and the goal is to transfer them to your local machine. The next set of examples will revolve around copying data from a Remote Source to a Local Destination. And third, using /* as shown in the testFolder/* example, will copy all of the individual files within the folder, but not the folder itself. Second, the -r flag is used anytime you want to recursively copy folders or folder contents. First, wildcards can be used when transferring groups of files or folders, such as when *.txt was used. While the SCP command is an excellent tool for. This implies that files sent using the SCP command are safe from eavesdropping, interception, and modification. There are three items worth noting from the examples listed above. The SCP command encrypts and authenticates data throughout the transfer process using the SSH protocol, making it more secure than conventional file transfer techniques such as FTP. Also, if you look closely at the destination, you'll notice that it is composed of multiple parts, the remote IP address (192.168.1.2), a colon (:), and where the file will end up on the target system (/home/user1/testFile.txt).Įxample: scp testFile.txt 192.168.1.2:/home/user1/testFile.txtĮxample: scp *.txt 192.168.1.2:/home/user1/Įxample: scp testFile1 testFile2 testFile3 192.168.1.2:/home/user1/Įxample: scp -r testFolder 192.168.1.2 :/home/user1/Įxample: scp -r testFolder/* 192.168.1.2 :/home/user1/ When breaking down the first example in our list below, we see that the scp command is given, followed by the local file, and then ending with the remote destination. O ur first set of examples will revolve around different ways to copy data from a local source to a remote destination. We're going to look at a few different use cases, which are intended to cover the most common ways in which SCP would normally be used. This means that when you’re building out your SCP commands, it will be from the data’s source location, to the intended destination, as shown here: The syntax for SCP is setup in a source/destination format. ![]() In fact, one of the primary benefits of using SCP for transferring data is that it’s based on the SSH protocols, which allow you to leverage the same authentication and security features found in SSH. Today we’re going to look at some examples of securely copying files and folders using the Secure Copy (SCP) functionality. Secure Copy (SCP) provides a secure means of copying files to and from NetStorage using SSH for authentication and security. See how to manage SSH keys.Secure Shell (SSH) has a lot of useful features, many of which were created for the express purpose of replacing insecure communications and data transfers. See how to set up public key authentication.ĭon't forget to establish proper SSH key management practices. The basic idea is to create a key pair on the client and copy the public key to the server into an authorized keys file. Actually, it is better than scp in many terms. Since scp is being deprecated, rsync is the next best tool for copying files between remote system over SSH. To avoid this, or to automate file copying in scripts, public key authentication is usually used. Method 2: Use rsync to copy files and directories over SSH. This would fetch path/directory from the host, copying it to the current working directory (creating directory in current working directory). To cpoy entire directory trees instead of single files, add the -r option. This fetches the file from the host, and puts it in the directory indicated by path. To copy a file from the remote host, use: scp host:file path It is possible to specify multiple files the last one is the destination. The destination path is optional, but can be a directory on the server, or even a file name if copying a single file. The basic usage of scp is as follows: scp file host:path ![]() Contents Basic usage Copying directory trees with scp Configuring public key authentication Basic usage
