FTP server (VSFTPD) can't connect to external network.
¡Hey! guys and girls.
I need your help. I finished to install FTP server (VSFTPD) in the local network (ftp://192.168.1.65:212) its so good to work, but when i try to connect to external network (ftp://ecicdocs.no-ip.org) i can't login, appears Error 530 not login.

This is my file config.

Code: Select all

# Example config file /etc/vsftpd.conf
#
# The default compiled in settings are fairly paranoid. This sample file
# loosens things up a bit, to make the ftp daemon more usable.
# Please see vsftpd.conf.5 for all compiled in defaults.
#
# READ THIS: This example file is NOT an exhaustive list of vsftpd options.
# Please read the vsftpd.conf.5 manual page to get a full idea of vsftpd's
# capabilities.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=NO
#
# Uncomment this to allow local users to log in.
local_enable=YES
#
# Uncomment this to enable any form of FTP write command.
write_enable=YES
#
# Default umask for local users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
local_umask=022
#
# Uncomment this to allow the anonymous FTP user to upload files. This only
# has an effect if the above global write enable is activated. Also, you will
# obviously need to create a directory writable by the FTP user.
#anon_upload_enable=YES
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#anon_mkdir_write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
dirmessage_enable=YES
#
# Activate logging of uploads/downloads.
xferlog_enable=YES
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=YES
#
# If you want, you can arrange for uploaded anonymous files to be owned by
# a different user. Note! Using "root" for uploaded files is not
# recommended!
chown_uploads=YES
#chown_user=whoever
#
# You may override where the log file goes if you like. The default is shown
# below.
xferlog_file=/var/log/vsftpd.log
#
# If you want, you can have your log file in standard ftpd xferlog format.
# Note that the default log file location is /var/log/xferlog in this case.
xferlog_std_format=YES
#
# You may change the default value for timing out an idle session.
idle_session_timeout=600
#
# You may change the default value for timing out a data connection.
data_connection_timeout=120
#
# It is recommended that you define on your system a unique user which the
# ftp server can use as a totally isolated and unprivileged user.
nopriv_user=user
#
# Enable this and the server will recognise asynchronous ABOR requests. Not
# recommended for security (the code is non-trivial). Not enabling it,
# however, may confuse older FTP clients.
#async_abor_enable=YES
#
# By default the server will pretend to allow ASCII mode but in fact ignore
# the request. Turn on the below options to have the server actually do ASCII
# mangling on files when in ASCII mode.
# Beware that on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
ascii_upload_enable=YES
ascii_download_enable=YES
#
# You may fully customise the login banner string:
ftpd_banner=Welcome to ECICDOCS
#
# You may specify a file of disallowed anonymous e-mail addresses. Apparently
# useful for combatting certain DoS attacks.
#deny_email_enable=YES
# (default follows)
#banned_email_file=/etc/vsftpd.banned_emails
#
# You may specify an explicit list of local users to chroot() to their home
# directory. If chroot_local_user is YES, then this list becomes a list of
# users to NOT chroot().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
chroot_local_user=YES
chroot_list_enable=YES
# (default follows)
chroot_list_file=/etc/vsftpd.chroot_list
#
# You may activate the "-R" option to the builtin ls. This is disabled by
# default to avoid remote users being able to cause excessive I/O on large
# sites. However, some broken FTP clients such as "ncftp" and "mirror" assume
# the presence of the "-R" option, so there is a strong case for enabling it.
ls_recurse_enable=YES
#
# When "listen" directive is enabled, vsftpd runs in standalone mode (rather
# than from inetd) and listens on IPv4 sockets. To use vsftpd in standalone
# mode rather than with inetd, change the line below to 'listen=YES'
# This directive cannot be used in conjunction with the listen_ipv6 directive.
listen=YES
listen_port=212
#
# This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6
# sockets, you must run two copies of vsftpd with two configuration files.
# Make sure, that one of the listen options is commented !!
#listen_ipv6=YES
tcp_wrappers=YES
pasv_enable=YES
pasv_min_port=20
pasv_max_port=212
I appreciate your attention.
Excellent day.

Your computer has an private/locale IP, that means it's not connecting directly to Internet.
So you must set a NAT rule on the device connected to Internet. All connection to this device on the ports 20 and 21 must be redirected to your locale address on the same port.

You need to configure port forwarding on your router to direct the external IP to the internal IP. You might also want to look into setting up a free account from DynDNS or other similar service if you do not have a static IP from your ISP.

Thanks for your advice.

But that is already done and the NAT and PORTWARDING income is that correct username and password and sends error session. : (
Now add the following line to / etc / inetd.conf
ftp stream tcp nowait root / usr / sbin / tcpd vsftpd
but the error persists.

The web is ftp://ecicdocs.no-ip.org

Username: user
Password: admin

in the local network work.
in the external network down.

Thanks!

I cannot ping the URL you provided which most likely means no type of connection can be made from the internet.

If your public IP is 187 136 22 78, nmap tells your host is down, no ports are open. Maybe you have not set up correctly your NAT rule, maybe you have a firewall.
If this IP is not yours, your domain name and the IP don't match.
