The client then sends a request for file operations, the server checks the permissions for the operation and returns with success of failure. The server returns with success and sends its supported version of the SFTP subsystem to the client. The client then asks the server to start the SFTP subsystem. The server authenticates and replies if access has been granted. The client then sends the user ID and password to the server. It checks the signature with the server public key if it does not match the connection is aborted from this point. The signature is sent to the client, the client also calculates the hash of all data exchanged. The server replies with its parameters and its public key, the server calculates a hash of all data exchanged so far and signs it using its private key. The client then starts the key exchange using an algorithm supported by both and sends it to the server. First, create an SFTP group with the following command: Next, create a new user named sftpuser and adds this user to the sftp group by running the following command. The server sends its supported algorithms and a small amount of random data as a session cookie, the client also sends it supported algorithms and a random session cookies.
The client then sends it SSH welcome message with the highest supported protocol version.
An SFTP client like FileZilla sends a connection request to the server sends the SSH welcome message with the highest supported protocol version. I tried having the local_root point to /var/SSH uses a public key cryptography to authenticate the server. The problem is that in the tutorial the FTP user has it's dedicated files directory ( /home/ftp_user/ftp/files), but I need to give the user access to the web root ( /var/www/html/site) for Wordpress performing the update. Therefore I installed vsftpd by following this tutorial. Everything works so far except for updating Wordpress automatically since it is asking for FTP access. I installed a LAMP stack already and installed Wordpress.
I used shared hosting providers before, but this time I'd like to set up the server from scratch with a VPS. I am currently setting up a website and I am trying to learn more about web servers on the way. How do I set up an FTP user with access to web root using vsftpd?
