vsftpd проблема

Проблема в том, что сервис vsftpd на данном IP и на данном порту не отвечает.

Нужно:

1. Проверить запущен ли вообще сервис.

>> systemctl status vsftpd

2. Посмотреть в конфиге сервиса /etc/vsftpd/vsftpd.conf какой IP и порт сервис должен слушать.

3. Проверить локально какой IP и порт слушает vsftpd

>> netstat -ltupn | grep vsftpd

4. Проверить не закрыт ли этот IP или порт файрволом (можно временно отключить файрвол и посмотреть не заработает ли, а потом разбираться с правилами).

Попробуйте:

или

Потом подключится.

Если не заработает покажите вывод:

1. Проверить запущен ли вообще сервис.
>> systemctl status vsftpd

# 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.

#

#

# Run standalone? vsftpd can run either from an inetd or as a standalone

# daemon started from an initscript.

listen=NO

#

# This directive enables listening on IPv6 sockets. By default, listening

# on the IPv6 "any" address (::) will accept connections from both IPv6

# and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6

# sockets. If you want that (perhaps because you want to listen on specific

# addresses) then you must run two copies of vsftpd with two configuration

# files.

listen_ipv6=YES

#

# Allow anonymous FTP? (Disabled by default).

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

#

# If enabled, vsftpd will display directory listings with the time

# in your local time zone. The default is to display GMT. The

# times returned by the MDTM FTP command are also affected by this

# option.

use_localtime=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

#

# 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.

#

# 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 blah FTP service.

#

# You may specify a file of disallowed anonymous e-mail addresses. Apparently

# useful for combatting certain DoS attacks.

# (default follows)

#

# 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

#

# 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

#

# Customization

#

# Some of vsftpd's settings don't fit the filesystem layout by

# default.

#

# This option should be the name of a directory which is empty. Also, the

# directory should not be writable by the ftp user. This directory is used

# as a secure chroot() jail at times vsftpd does not require filesystem

# access.

secure_chroot_dir=/var/run/vsftpd/empty

а как дела с iptables?

4-й пункт сделайте.

Отключите файрвол:

>> systemctl stop ip6tables

или, если Вы новый файрвол используете:

>> systemctl stop firewalld

И проверьте.

Кстати, а компьютер, с которого Вы пытаетесь по FTP подключиться, может работать по IPv6?

у вас vsftpd работает только по IPv6

в конфиге вместо

listen=NO

поставьте

listen=YES

и перезапустите vsftpd

и проверьте

sudo netstat -npl

ЗЫ: Если у вас нет IPv6 адреса то отключите IPv6 в конфиге, поставьте

listen_ipv6=NO

Здравствуйте, сделал как вы сказали не помогло

Извините, но, Вы неправильный совет даете.

Если ему последовать и одновременно и НЕ прописать:

listen_ipv6=NO,

то vsftp просто не запустится, т.к. он не может одновременно работать по IPv4 и IPv6, о чем недвусмысленно написано в комментариях в конфиге:

"If you want that (perhaps because you want to listen on specific

addresses) then you must run two copies of vsftpd with two configuration

files."

acbirja,

У Вас:

- vsftp запущен и слушает 21 порт на любом IPv6

- файрвол отключен.

Должно все работать.

Попробуйте локально подсоединиться телнетом:

>> telnet IP_address 21

где вместо "IP_address" подставьте IPv6 адрес, прописанный на вашем сервере.

Если соединится (должен), попробуйте ту же операцию проделать с удаленного компа.

все нормально, vsftpd запущен и слушает порт

должно работать
