How to connect via ftp to ubuntu?

Question

FTP

Good day!
I'm trying to connect via ftp.
Writes that access is denied.
By lakalka 192.168.1.100 It connects. There is no external ip
ip white 85.172.205.66
Through root does not enter, too, writes access denied.
How can I fix this error. Ubuntu is worth it.
ftp installed. The port is open.
In the logs it is

Each user got only in the folder?

Answer 1

look at the firewall settings - is the port open for packet access.
see the corresponding logs.
you can close a user in your own folder via chroot
for vsftpd this is so
# You may restrict local users to their home directories. See the FAQ for
# the possible risks in this before using chroot_local_user or chroot_list_enable below.
chroot_local_user=YES
