Control Linux users can use FTP connection to specify directory, and cannot connect with SSH

There are two versions, on-line version I tried not to, later I touched out another feasible:

The first is the online version:

#mkdir/home/ftp #创建ftp根目录
#useradd-D/home/ftp-s/sbin/nologin ftpuser #创建用户 (note home directory and non-login)
#passwd Ftpuser #设置用户密码
#chown-R ftpuser/home/ftp
#chmod 755-r/home/ftp #改变ftp根目录属主和权限
#echo "Ftpuser" >>/etc/vsftpd.user_list #把ftpuser加入到允许访问的队伍 my version: To create an FTP user first: useradd-d/hom E/ftp Ftpuser then create the password: passwd ftpuser Add a login to the/etc/ssh/sshd_config account, if you only allow root login to write: Allowusers root your FTP account, did not write up, Of course, you are not allowed to log in with SSH. At this time add Ftpuser to/etc/vsftpd/chroot_list, then you use Ftpuser login FTP can only access you create the designated/HOMT/FTP directory.
