 |
|
ciao ragazzuoli stavo configurando il suddetto server , tutto ok a parte che anche avendo inserito nel file di configurazione
| Code: | # 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_local_user=YES
ls_recurse_enable=NO
#chroot_list_enable=NO
# (default follows)
#chroot_list_file=/etc/vsftpd/chroot_list
|
gli utenti autenticati non sono chrootati mentre dovrebberlo esserlo , il problema e che mi servirebbe poter far accedere solo persone a cui creo io un account e che siano chrootate nella loro home e non possano andare in giro.

perchè dal manuale di vsftpd dice che se abilitata la voce chroot_local_user quelli inseriti in quella lista sono gli utenti non chrootati.

d'altronde se NON usi chroot_local_user, la direttiva chroot_list_file specifica un elenco di utenti che devono essere posti in chroot |

eh lo so ma ho provato con piu persone se mi collego dalla macchina dove ho il server ftp se do per esempio cd / vedo solo la home dell utente con cui mi sono cellegato al ftp ma se lo faccio fare a miei amici dall esterno della mia rete e per esempio danno cd /etc , vedono i file , quindi escono dal chroot.

ti posto il file di conf
| Code: |
#
# Enable vsftpd to run as a standalone daemon
# Comment these two out to run under inetd or xinetd
background=YES
listen=YES
# Allow anonymous FTP?
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
anon_umask=0777
file_open_mode=0777
# 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
# 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
# Activate logging of uploads/downloads.
xferlog_enable=YES
# If you want, you can have your log file in standard ftpd xferlog format
#xferlog_std_format=YES
# You may override where the log file goes if you like.
xferlog_file=/var/log/vsftpd.log
# 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=nobody
# 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 turning on ascii_download_enable enables malicious remote parties
# to consume your I/O resources, by issuing the command "SIZE /big/file" in
# ASCII mode.
# These ASCII options are split into upload and download because you may wish
# to enable ASCII uploads (to prevent uploaded scripts etc. from breaking),
# without the DoS risk of SIZE and ASCII downloads. ASCII mangling should be
# on the client anyway..
#ascii_upload_enable=YES
#ascii_download_enable=YES
# You may fully customise the login banner string:
ftpd_banner=Welcome to Nightwish FTP service.
# 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().
chroot_local_user=YES
ls_recurse_enable=NO
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
max_per_ip=2

lasciando il file etc/vsftpd/chroot_list vuoto come dice il commento.
