Today, we will be discussing about how to sync files using rsync with non-standard SSH port. You might wonder why do we need to use non-standard SSH port? It is because of security reasons. Everybody knows\u00a022<\/strong>\u00a0is the SSH default port.<\/p>\n

Rsync Files Over SSH Non-standard Port<\/p>\n<\/div>\n

So, It is mandatory to change your SSH default port number to something different which is very hard to guess. In such cases, how will you sync your files\/folders with your Remote server? No worries, It is not that difficult. Here we will see how to sync files and folders using rsync with non-standard SSH port.<\/p>\n

As you might know,\u00a0rsync<\/strong>, also known as\u00a0Remote Sync<\/strong>, is a fast, versatile, and powerful tool that can be used to copy and sync files\/directories from local to local, or local to remote hosts. For more details about rsync, check man pages:<\/p>\n

# man rsync\r\n<\/pre>\n
Or refer our previous guide from the link below.<\/p>\n

  1. Rsync: 10 Practical Examples of Rsync Command in Linux<\/a><\/li>\n<\/ol>\n
    Change SSH Port to Non-standard Port<\/h3>\n
    As we all know, By default rsync uses default SSH port\u00a022<\/strong>\u00a0to sync files over local to remote hosts and vice versa. We should change our remote server\u2019s SSH port to tighten the security.<\/p>\n
    To do this, open and edit the SSH configuration\u00a0\/etc\/ssh\/sshd_config<\/strong>\u00a0file:<\/p>\n
    # vi \/etc\/ssh\/sshd_config \r\n<\/pre>\n
    Find the following line. Uncomment and change the port number of your choice. I recommend you to choose any number which is very hard to guess.<\/p>\n
    Make sure you are using a unique number which is not used by existing services. Check this\u00a0netstat article<\/a>\u00a0to know which services are running on which TCP\/UDP ports.<\/p>\n
    For example, here I use port number 1431.<\/p>\n
    [...]\r\nPort 1431\r\n[...]\r\n<\/pre>\n
    Save and close the file.<\/p>\n
    In RPM based systems such as\u00a0RHEL<\/strong>,\u00a0CentOS<\/strong>, and\u00a0Scientific Linux 7<\/strong>, you need to allow the new port through your firewall or router.<\/p>\n
    # firewall-cmd --add-port 1431\/tcp\r\n# firewall-cmd --add-port 1431\/tcp --permanent\r\n<\/pre>\n
    On RHEL\/CentOS\/Scientific Linux 6 and above, you should also update\u00a0selinux<\/strong>\u00a0permissions to allow the port.<\/p>\n
    # iptables -A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1431 -j ACCEPT\r\n# semanage port -a -t ssh_port_t -p tcp 1431\r\n<\/pre>\n
    Finally, restart SSH service to take effect the changes.<\/p>\n
    # systemctl restart sshd        [On SystemD<\/strong>]\r\nOR\r\n# service sshd restart          [On SysVinit<\/strong>]\r\n<\/pre>\n
    Now let us see how to sync files using rsync with non-standard port.<\/p>\n
    How to Rsync with non-standard SSH Port<\/h3>\n
    Run the following command from the terminal to sync files\/folders using Rsync with non-standard ssh port.<\/p>\n
    Syntax:<\/h5>\n
    # rsync -arvz -e 'ssh -p <port-number><\/strong>' --progress --delete user@remote-server:\/path\/to\/remote\/folder \/path\/to\/local\/folder\r\n<\/pre>\n
    For the purpose of this tutorial, I will be using two systems.<\/p>\n
    Remote System Details:<\/h4>\n
    IP Address: 192.168.1.103\r\nUser name: tecmint\r\nSync folder: \/backup1\r\n<\/pre>\n
    Local System Details:<\/h4>\n
    Operating System: Ubuntu 14.04 Desktop\r\nIP Address: 192.168.1.100\r\nSync folder: \/home\/sk\/backup2\r\n<\/pre>\n
    Let us sync the contents of remote server\u2019s\u00a0\/backup1<\/code>\u00a0folder to my local system\u2019s folder\u00a0\/home\/sk\/backup2\/<\/code>.<\/p>\n
    $ sudo rsync -arvz -e 'ssh -p 1431' --progress --delete tecmint@192.168.1.103:\/backup1 \/home\/sk\/backup2\r\n<\/pre>\n
    Sample Output<\/h5>\n

    Let us check the contents of\u00a0\/backup1\/<\/code>\u00a0folder in the remote server.<\/p>\n
    $ sudo ls -l \/backup1\/\r\n<\/pre>\n
    Sample Output<\/h5>\n

    Now, let us check the contents of\u00a0\/backup2\/<\/code>\u00a0folder of local system.<\/p>\n
    $ ls \/home\/sk\/backup2\/\r\n<\/pre>\n
    Sample Output<\/h5>\n

    As you see in the above output, the contents of\u00a0\/backup1\/<\/code>\u00a0have been successfully copied to my local system\u2019s\u00a0\/home\/sk\/backup2\/<\/code>\u00a0directory.<\/p>\n
    Verify\u00a0\/backup1\/<\/code>\u00a0folder contents:<\/p>\n
    $ ls \/home\/sk\/backup2\/backup1\/\r\n<\/pre>\n
    Sample Output<\/h5>\n

    See, both remote and local system\u2019s folders have same files.<\/p>\n
    Conclusion<\/h3>\n
    Syncing files\/folders using Rsync with SSH is not only easy, but also fast and secure method. If you\u2019re behind a firewall that restricts port 22, no worries. Just change the default port and sync files like a pro.<\/p>\n
