sorry for dumb question, but I am a newbie in Ubuntu administration.
I configure vsftpd service and it work fine when user connect thought FTP
But when user connect thought SFTP vsftpd not used (I stop vsftpd to check)
I see that ftp user "sy" has running process /usr/lib/openssh/sftp-server
How I can "switch" this process with vsftpd to use it for SFTP connection?
found possible solution
I'll try and comment if successful
