This is how we copy a file to a remote destination connecting to port 44 instead of 22: $ scp -P 44 path/to/ local/file.ext :path/to/remote/file.ext Modification/Access Time However, this can be overridden by supplying the -P flag, followed by the port number. Changing the PortДЄs mentioned before, SCP operates on port 22 by default. The scp command has some useful options (also known as flags) that can alter aspects of how it connects to a remote host. Let's see how we can use command-line options to modify its behavior. The SCP command also has configurations for greater flexibility in what and how we copy. The simplicity and flexibility of SCP has made it popular with system administrators. We may transfer files between our main remote host and a backup server with scp.

#Ssh copy file to remote update#

We may transfer files between our local and remote machines to test and update the server or application configurations.

This versatility makes it very useful for scripts.

#Ssh copy file to remote password#

A password prompt will be presented to accept login credentials for each user.ДЇrom all these variations of file copying we see that the scp command is flexible on what can be the source or destination path. Each has to have access to their respective remote server. Notice that in this case, two remote users must be specified. Transferring a Remote File to a Remote DestinationДЇinally, the following command format is used to transfer a file between two remote hosts: $ scp :path/to/remote/file.ext :path/to/remote/file.ext Let's have a look at transferring a file between two remote hosts. But, when complete, you should have a new file in the folder you specified. This works essentially in the same way, except that the remote user, host, and path are now specified before the local path.ДЄ prompt will still be displayed for the password belonging to the remote host's user account. $ scp :path/to/remote/file.ext path/to/ local/file.ext In a very similar fashion, we can copy a file from a remote computer to our local machine: Transferring a Remote File to a Local Destination

#Ssh copy file to remote how to#

Now that we know how to transfer a remote file to our local machine, let's discuss the reverse scenario - transferring a file from a remote host to the local host. If you can't use your credentials to log in remotely with ssh, then those credentials will not work when using scp. This user account must have access to the remote path specified in the command. Once the password is entered, the file will be copied. We then specify where we want to copy the file to on the remote machine after the colon ( :).ДЄfter running this command, a prompt will display for the password corresponding to the remote host's user account: $ 's password:.The remote-host supplied is the domain name or the IP address of the remote machine we are trying to connect to.The username has to belong to a user of the remote machine. The user supplied in the command is the username.This command will copy the local file file.ext to the specified path (after the colon) on the remote-host. I'd go with the subprocess module if using version 2.4+.$ scp path/to/ local/file.ext :path/to/remote/file.ext If opting for the system-call path, Python offers an array of options such as os.system or the commands/subprocess modules. I gave Conch the once-over some time ago but it didn't appeal to me. I've used Paramiko with an eye towards replacing system calls but found myself drawn back to the wrapped commands due to their ease of use and immediate familiarity. NOTE: its hard to beat rsync if you plan on transferring files via SSH, especially if the alternative is plain old scp. It probably goes without saying that SSH keys are almost always a better idea than passwords for this sort of stuff. You will need to setup SSH keys to enable password-less logins if you are wrapping system commands like 'ssh', 'scp' or 'rsync.' You can embed a password in a script using Paramiko or some other library, but you might find the lack of documentation frustrating, especially if you are not familiar with the basics of the SSH connection (eg - key exchanges, agents, etc). use a Python library that provides SSH capabilities (eg - Paramiko or Twisted Conch)Д®ach approach has its own quirks.

There are a couple of different ways to approach the problem:
