Hi there.
I am being used for SFTP.

However, I need an FTP installation situation.
Because I now need the support of WordPress themes support.
They asked for an FTP account to me.

I made sure the man down.

I succeeded to the FTP installation, the connection has failed.

So any questions.
Question 1. I want to create a support account and password. (Ex: ftp account: support)
Question 2. I want to support the home directory of the account to / var / www / html.
Question 3. How do I set the permissions of the support account?
Question 4. I want to stop the FTP service when you do not need the help of specialists.

Thank you.
