Hallo,

hab hier einen 12 LTS erver aufgesetzt der als Fileserver arbeiten soll, Samba geht auch ohne Probleme aber Vsftpd geht nicht, die lokalen User können sich nicht per FTP anmelden Die lokalen User sollen nur in Ihr Homeverzeichnis kommen!

# 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=YES
#
# Run standalone with IPv6?
# Like the listen parameter, except vsftpd will listen on an IPv6 socket
# instead of an IPv4 one. This parameter and the listen parameter are mutually
# exclusive.
#listen_ipv6=YES
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
#anonymous_enable=YES
#
# 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
#chown_username=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=240
#
# 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=ftpsecure
#
# 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 Fileserver
#
# 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 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/vsftp.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
#
# This string is the name of the PAM service vsftpd will use.
#pam_service_name=vsftpd
#
# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
#rsa_cert_file=/etc/ssl/private/vsftpd.pem

Siehe hier: klick

danke aber geht nicht!

wenn ich das so mache wie in dem anderem Beitrag, also:

- vsftp.user_list anlege den user eintrage

- vsftp.conf löschen

- vsftpd.conf neu erstelle den Inhalt rein kopiere

und dann den Server neustarten will kommt im syslog:

ich will den Server auch nur Lokal nutzen!

Hatte einen Fehler beim kopieren gemacht ☹ Der Dienst läuft aber leider kann ich mich nicht einloggen!

gewollt ist das sich jeder lokale User per FTP einloggen kann ( nur im Homeordner )

kannebecker schrieb:

Poste mal die Ausgabe von:

cat /etc/pam.d/vsftpd

der Inhalt:

# Standard behaviour for ftpd(8).
auth    required        pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed

# Note: vsftpd handles anonymous logins on its own. Do not enable pam_ftp.so.

# Standard pam includes
@include common-account
@include common-session
@include common-auth
auth    required        pam_shells.so

Grundsätzlich sieht deine vsftpd.conf richtig aus.

Bitte poste mal deine /etc/passwd. Wurden allen Usern ein Homeverzeichniss zugewiesen?

Wurde der Login per SSH verboten? Also statt /bin/bash → /bin/false in der passwd?

Wenn ja, wurde in der /etc/shells die Zeile /bin/false aufgenommen?

LG 7

Mein User in der passwd:

edv9945:x:1001:100:Kannebecker,,,:/shares/userhomes/edv9945:/bin/bash

/etc/shells:

# /etc/shells: valid login shells
/bin/sh
/bin/dash
/bin/bash
/bin/rbash
/usr/bin/tmux
/usr/bin/screen

Also folgendes sollte bei dir einkommentiert sein in der vsftpd.conf:

1
2
3

secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
dirmessage_enable=YES

bitte trage hinter den usern in der /etc/passwd statt /bin/bash ein /bin/false ein, und füge diese ebenfalls in der /etc/shells hinzu.

leider ohne Erfolg:

Hmm.. komische Gesichte...

was sagt ein telnet und manueller login über port 21?

Nimm bitte nochmal beide punkte raus: #chroot_list_enable=YES #chroot_local_user=YES

Aber grundstäzlich ist deine Config richtig... weiß nicht ob es an der 12 Version liegt.... :/

Das ist die aktuelle vsftp.conf

ftpd_banner=Welcome to Fileserver
listen=YES
local_enable=YES
write_enable=YES
download_enable=YES
use_localtime=YES
xferlog_enable=YES
connect_from_port_20=YES
idle_session_timeout=240
data_connection_timeout=120
chroot_local_user=YES
secure_chroot_dir=/var/run/vsftpd/empty
pam_service_name=vsftpd
anonymous_enable=NO
dirmessage_enable=YES

mit auskommentierter chroot_local_user=YES das gleiche

Unter 10.04 LTS ging es aber der Server bzw. die VM-Ware ist hin ☹

du hast nun aber auch in der /etc/passwd → /bin/false eingetragen

und diese auch in der /etc/shells hinterlegt?
