2.3 Check FTP connection
Check with FTP client
In this case, we will use FileZilla.
Start FileZilla select "Site Manager" from the "File" menu.
Click on "New site" and then
Protocol : FTP- File Transfer Protocol
Host : Server IP Address
Port :
Encryption : Use explicit FTP over TLS if avaiable
Logon Type : Ask for password
User : Login User
Password : logd in user password
If the Windows directory appears on the left and the Ubuntu directory on the right, the connection is successful.
