usermod -d /home/data user5

vi /etc/vsftpd/vsftpd.conf

edit nonymous_enable=no chroot_local_user=YES chroot_list_enable=YES chroot_list_file=/etc/vsftpd/chroot_list

cd /home/vsftpd

touch chroot_list

setsebool -P allow_ftpd_full_access 1

when i am using ftp site outside network using filezilla its working fine using port number 21. user1,user2,user3,user4 only access the home directory only. user1 can’t go another users directory. user5 access only four users home directory. when user1 access ftp site using sftp and port number 22 using user1 access remaining users accounts also. so how i can restrict user 1.
