check that I currently have a user aaa who can log in to ftp (using sftp)
but when I want to log in using root, he won"t let me log in
how to implement it can also use root to log in to ftp?
because some path files cannot be edited, because they are not root
ubuntu starts from 14.04. by default, ssh does not allow root password to log in, because PermitRootLogin prohibit-password is enabled. So you can do a lot of things, for example, you can log in to root, by key authentication or modify the configuration file of sshd to allow root to log in with a password.
but logging in directly with root is not a good solution, so it is recommended that you operate as an ordinary user and use sudo to raise rights
