Unable to run vsftpd command

I am using Sierra 10.12.6 and by using Homebrew, vsftpd is installed so that I can set up an FTP server my iPad can connect to. However, I can't run the command vsftd: zsh: command not found: vsftpd But when I try to install vsftpd again, i see that *Warning: vsftpd 3.0.3 is already installed I can do man vsftpd and that works fine. I run which vsftpd at root, this returns vsftpd not found I went to the vsftpd config file and also set listen=YES So how do I run vsftpd?
