How to connect to non-default sftp port?

To connect to an SFTP server using a non-default port, you will need to use an SFTP client that allows you to specify a custom port number. Most SFTP clients have this capability.

Here are some examples of how you might specify a custom port number when connecting to an SFTP server using a few common SFTP clients:

  • OpenSSH sftp client:
ftp -o Port=2222 user@example.com
  • FileZilla:
  1. In the “Host” field, enter the hostname or IP address of the SFTP server, followed by a colon and the port number. For example: example.com:2222.
  2. Enter your username and password when prompted to log in.
  • WinSCP:
  1. In the “Host name” field, enter the hostname or IP address of the SFTP server.
  2. In the “Port number” field, enter the custom port number.
  3. Enter your username and password when prompted to log in.

Keep in mind that you will need to know the correct username and password for the SFTP server in order to log in. If you are unsure of these credentials, you will need to contact the administrator of the server for assistance.

To configure a non-default SFTP port, you will need to edit the configuration file for the SFTP server you are using. The location of this file may vary depending on the specific SFTP server software you are using. Some common locations for this file include:

  • /etc/ssh/sshd_config (OpenSSH)
  • /etc/sftp/sshd_config (ProFTPD with mod_sftp)

Once you have located the configuration file, you can edit it to change the port number. Look for a line that begins with Port and change the number after it to the desired port number. For example, to change the port to 2222, the line would look like this: Port 2222.

After you have made the necessary changes to the configuration file, you will need to restart the SFTP server for the changes to take effect. The specific command to do this will depend on the SFTP server software you are using. For example, to restart the OpenSSH SFTP server, you would use the following command:

sudo service ssh restart

Keep in mind that changing the SFTP port number can potentially increase the security of your server, as it makes it less likely for an attacker to find and exploit the SFTP service. However, it is also important to remember that changing the port number can also make it more difficult for legitimate users to connect to the SFTP server, as they will need to specify the new port number when connecting.

Here are a few more examples of how you might specify a custom port number when connecting to an SFTP server using some other common SFTP clients:

  • lftp:
lftp sftp://user@example.com:2222
  • psftp (PuTTY SFTP client):
psftp -P 2222 user@example.com
  • sftp (Linux/macOS command line):
sftp -P 2222 user@example.com

Keep in mind that these are just a few examples of how you might specify a custom port number when connecting to an SFTP server. The specific syntax and options may vary depending on the SFTP client you are using. If you are using a different SFTP client, you may need to consult the documentation for that specific client to learn how to specify a custom port number when connecting.
