Vsftpd sur dédié

Bonjour à tous,

J’ai un serveur dédié avec une debian of course.
J’ai 1 site web dans le dossier /var/www/monsite

Je dois installer vsftp sur ce dédié avec un seul utilisateur,
qui ne verra que le dossier /var/www/monsite et son contenu.

les permissions et le proprio de /var/www/monsite
est bien sûr
www-data:www-data en 755.

La personne qui se connectera en ftp pourra modifier et créer des fichiers et des dossiers.

Comment faire en sorte que la création/écriture soit toujours avec l’utilisateur
www-data:www-data avec les droits 755 dans le dossier /var/www/monsite ?

je cherche depuis 1h et je trouve rien qui convient … :confused:

Merci d’avance
Guillaume

Est-ce que tu comprends l’anglais manualo-nulixique contemporain ?

VSFTPD.CONF(5) File Formats Manual VSFTPD.CONF(5)

NAME
vsftpd.conf - config file for vsftpd

DESCRIPTION
vsftpd.conf may be used to control various aspects of vsftpd’s behaviour. By default, vsftpd looks for this file at the location /etc/vsftpd.conf.[/code]

/etc/vsftpd.conf
Outre la configuration, le fichier contient des explications commentées (#) qui servent de guide. Ces explications sont en jargon anglo-nulixien bien entendu. Il y est fait mention de umask=022.
Copie ici le retour de la commande

Oui, je comprends l’anglais manualo-nulixique contemporain !

/etc/vsftpd.conf

[code]# 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=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
chown_username=www-data

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=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

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/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

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[/code]

J’ai créé cet utilisateur avec ceci :

Puis je lui ai donné un mot de passe, avec passwd ftpcollectif.

cat /etc/vsftpd.chroot_list ftpcollectif
J’aimerais que “ftpcollectif” arrive à la racine du serveur web finalement.

Merci pour ton aide
Guillaume
