Merçi pour vos suggestions très intéressantes.
Je viens de tout ré-installer.
Pour cette installation, je me suis inspiré de “Linux Identity Pack n° 7 - Debian 5.0” article “Serveur NAS boosté” p 23 et suivantes.
Après avoir rechargé vsFTPD la commande :
-> dpkg -l | grep ftp
me donne :
ii ftp 0.17-18 The FTP client
ii gnome-vfs-obexftp 0.4-1 GNOME VFS module for OBEX FTP
ii vsftpd
J’ai laissé fstab tel qu’indiqué ci-dessous et n’ai pas changé vsftpd.conf. (Il m’est évident, maintenant, qu’il eut été judicieux de faire cet essai avant de me manifester).
Tout semble fonctionner (je peux accéder, sauf erreur, au serveur depuis le Mac). Sauf que j’ai du changer le propriétaire (de root vers user) du répertoire /home/ftp/ pour pouvoir, depuis le Mac, déposer un fichier.
Avant, depuis le Mac, il me demandait un user/password lorsque j’essayais de me connecter au serveur. Maintenant, il ne me demande plus rien et l’accés est immédiat.
Cela doit provenir du fait que j’ai, de base :
local_enable=No
alors qu’avant, dans mon fichier j’avais :
local_enable=Yes
Je vais réfléchir autour de cela.
Merci par avance pour tout autre suggestion de votre part.
Sincéres salutations.
fstab :
Le même article demande de faire :
-> mkdir /home/user/partage
-> echo ‘/home/user/partage auto bind, defaults 0 0’ >> /etc/fstab
La ligne de fstab correspondante est alors :
/home/bernard/partage-ftp auto bind,defaults 0 0
Je ne suis pas très convaincu sur la régularité de cette ligne. Qu’en pensez-vous ?
Fichier vsftpd.conf
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
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
#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=“Bienvenue sur mon site FTP”
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().
#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
Debian customization
Some of vsftpd’s settings don’t fit the Debian filesystem layout by
default. These settings are more Debian-friendly.
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
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/certs/vsftpd.pem
selon Debian 5.0
local_umask = 002
