Allow FTP to a subdomain

Hosting several URL’s on a VPS. I want/need to allow jack to ftp to The VPS control panel says I can allow jack access to all domains then he would cd to domain3 then to sub.

Is there a way to allow jack to ftp to directly and no where else?


Set that subdomain to be hosted under a new user, and don’t put any other domains on that user.

OK, that was easy. http works fine.
Now: ftp
ftp: connect: Connection refused

I’m missing something somewhere.

Changed user from ftp to sftp and told him to download Gftp.
From what I can tell if you have VPS you do sftp, you do not do ftp.
