Use SFTP and SCP
Secure File Transfer Protocol (SFTP) and Secure Copy (SCP) use Secure Shell (SSH) to transfer files. We recommend using these protocols instead of the FTP protocol, which transfers files in plain text.
Install and use SCP
By default, SCP is available for all Rackspace® Cloud Servers. Use the OpenSSH package to install SCP if the scp command does not exist on your Linux® computer.
To install SCP on CentOS® and Red Hat® Enterprise Linux 7:
$ sudo yum install -y openssh-clients
To install SCP on Ubuntu® and Debian®:
$ sudo apt install -y openssh-client
Configure a user on a remote server and use the following command to copy files to the remote server, where remoteserver is the IP address or hostname of the remote server:
$ scp username@remoteserver:/path/to/remote/directory/ /path/to/local/machine/directory
Use the following command to copy a file from your local machine to the remote server:
$ scp /path/to/filename.ext username@remoteserver:/destination/path'
SCP connection and commands
You can use SCP to upload and download files and images.
Upload and download files
The ll command shows the directories under the scpuser home directory:
# ll /home/scpuser
down
up
You can download files from the down directory of the server and upload files to the up directory of the server.
To download files from the server to a local machine, use the following command:
$ scp -r [email protected]:/home/scpuser/down /home/mylocaluser/downloads

SFTP configuration
To connect to a server with SFTP to upload or download files, use the following command, where remoteserveris the IP address or hostname of the remote server:
$ sftp username@remoteserver
To find the IP address of a server, use the ipconfig command. In the following example, the server hostname is test has an IP address of 23.253.20.165:
[test ~]# ifconfig
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 23.253.20.165
Refer to our configure an SFTP user article for more guidance.
SFTP connection
Perform the following steps to set up an SFTP connection:
-
Configure an SFTP user on the remote host.
-
Jail the user in a directory, such as /var/www/html/test.
-
Change to the directory in the local machine where you plan to upload or download files.
-
Log in to the remote SFTP server.
For example:
-
Change to the directory on the local machine:
$ cd /home/mylocaluser/sftp
-
List the files in the directory:
$ ls /home/jorg1234/sftp
LocalComp.gif test1.txt themes.tar.gz -
Upload the contents of the local directory to the remote server:
[sftp]$ sftp [email protected]
[email protected]'s password:
Connected to 23.253.20.165.
