Hallo...

Ich habe ein kleines Problem mit meinem SuSe 10.1 Server...

Ich habe vsftp installiert und auch konfiguriert.

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.
#
# If you do not change anything here you will have a minimum setup for an
# anonymus FTP server.
#
# 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.

# General Settings
#
# Uncomment this to enable any form of FTP write command.
#
write_enable=YES
#
# Activate directory messages - messages given to remote users when they
# go into a certain directory.
#
dirmessage_enable=YES
#
# 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
#
# You may fully customise the login banner string:
#
ftpd_banner="Welcome to our TPS-PO FTP Server."
#
# 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
#
# 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
#
# If  enabled,  all  user  and  group  information in
# directory listings will be displayed as "ftp".
#
#hide_ids=YES

# Local FTP user Settings
# 
# Uncomment this to allow local users to log in.
#
local_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 to put local users in a chroot() jail in their home directory
# after login.
#
#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
#
# The maximum data transfer rate permitted, in bytes per second, for
# local authenticated users. The default is 0 (unlimited).
#
#local_max_rate=7200


# Anonymus FTP user Settings
#
# Allow anonymous FTP?
#
#anonymous_enable=YES
#
# Anonymous users will only be allowed to download files which are
# world readable.
#
#anon_world_readable_only=YES
#
# 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
#
# Default umask for anonymus users is 077. You may wish to change this to 022,
# if your users expect that (022 is used by most other ftpd's)
#
#anon_umask=022
#
# Uncomment this if you want the anonymous FTP user to be able to create
# new directories.
#
#anon_mkdir_write_enable=YES
#
# Uncomment this to enable anonymus FTP users to perform other write operations
# like deletion and renaming.
#
#anon_other_write_enable=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
#
# The maximum data transfer rate permitted, in bytes per second, for anonymous
# authenticated users. The default is 0 (unlimited).
#
#anon_max_rate=7200


# Log Settings
#
# Log to the syslog daemon instead of using an logfile.
#
syslog_enable=YES
#
# Uncomment this to log all FTP requests and responses.
#
log_ftp_protocol=YES
#
# Activate logging of uploads/downloads.
#
xferlog_enable=YES
#
# You may override where the log file goes if you like. The default is shown
# below.
#
vsftpd_log_file=/var/log/vsftpd.log
# 
# If you want, you can have your log file in standard ftpd xferlog format.
# Note: This disables the normal logging unless you enable dual_log_enable below. 
#
#xferlog_std_format=YES
#
# You may override where the log file goes if you like. The default is shown
# below.
#
#xferlog_file=/var/log/xferlog
#
# Enable this to have booth logfiles. Standard xferlog and vsftpd's own style log.
#
#dual_log_enable=YES
#
# Uncomment this to enable session status information in the system process listing.
#
#setproctitle_enable=YES

# Transfer Settings
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
#
connect_from_port_20=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
#
# 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
#
# Set to NO if you want to disallow the  PASV  method of obtaining a data
# connection.
#
#pasv_enable=NO

# PAM setting. Do NOT change this unless you know what you do!
#
pam_service_name=vsftpd

# Set listen=YES if you want vsftpd to run standalone
#
#listen=YES

# Set to ssl_enable=YES if you want to enable SSL
#ssl_enable=YES

#Own Settings
local_root=/ftp

Wie man sieht landet man nach der Anmeldung in /ftp. Ich kann von dort aber als user aus dem Verzeichnis raus und in alle anderen Verzeichnisse rein. Was ich nicht will.

EDIT: Ich seh grad er kann doch in den anderen Verzeichnissen Dateien anzeigen. Dat ist nicht gut.

Wie kann ich jetzt sagen das er nur im Verzeichnis /ftp bleiben kann?

Ich habs schon mit

chroot_local_user=YES

probiert, aber dann kann ich nicht mal in Verzeichnis /ftp etwa machen. Ich schätze mal er sperrt mich zwar im Homervezeichniss ein wechselt aber doch ins /ftp und blockiert mich dadurch...

Ich habs schon mit der Boardsuche hier versucht und mit Google, aber habe nichts passendes gefunden.

Hat hier wer vielleicht einen kleinen Tip für mich?

Bei Fragen bitte Fragen...

thx

Gruß

hmm man kann doch in der config festlegen welche commands die user ausfuehren duerfen...

sowas wie:

Code:
cmds_allowed=ABOR,CWD,CDUP,LIST,MDTM,PASS ...

muesstest dann ja theoretisch einfach alle commands zum wechseln der verzeichnisse rausnehmen (CWD,CDUP, ...)

nur mal so ne ueberlegung :D


kannst das ja einfach mal googlen da findest bestimmt was
