vsftpd - brauche hilfe um benutzerzugang einzurichten

[R.S.]

HI,

versuche seit kurzem einen ftp-benutzerugang zur fernadministration des Servers (apache2) auf suse 9.0 einzurichten. Habe mich bereits bei google u. div. foren schon informiert konnte aber leider noch keine passende anrwort auf meine Fragen finden.

Was mal dabei rauskommen soll:

Der Benutzer den ich einrichte soll sich über ftp auf meinem Server einklinken können, und dabei alle rechte besitzten die auch ich als root habe um z.B. neue Software zu installieren u. konfigurieren.

Im Verzeichniss /home/xyz habe ich den neuen Benutzer bereits angelegt bzw. die Passwörter in /etc/passwd vergeben.

Das Verzeichniss /etc/vsftpd.conf sieht bislang so aus :

Example config file /etc/vsftpd.conf

The default compiled in settings are very paranoid. This sample file

loosens things up a bit, to make the ftp daemon more usable.

If you dont change anything here you will have a minimum setup for an

anonymus FTP server.

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 FOOBAR FTP service."

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

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

Activate logging of uploads/downloads.

xferlog_enable=YES

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

Uncomment this to log all FTP requests and responses. This only works if

xferlog_std_format is not enabled. Beware, it will create a huge amount of data

in your logfile.

#log_ftp_protocol=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

Das Verzeichniss /etc/xinetd.d sieht wie folgt aus:

default: off

description:

#   The vsftpd FTP server serves FTP connections. It uses
#   normal, unencrypted usernames and passwords for authentication.

vsftpd is designed to be secure.

service ftp
{
        socket_type             = stream
        protocol                = tcp
        wait                    = no
        user                    = root
        server                  = /usr/sbin/vsftpd
#        server_args             =
#        log_on_success          += DURATION USERID
#        log_on_failure          += USERID
#        nice                    = 10
        disable                 = yes
}

Das Verzeichniss /etc/pam.p/vsftpd so:

#%PAM-1.0

Uncomment this to achieve what used to be ftpd -A.

auth       required     pam_listfile.so item=user sense=allow file=/etc/ftpchroot onerr=fail

auth     required       pam_listfile.so item=user sense=deny file=/etc/ftpusers onerr=succeed

Uncomment the following line for anonymous ftp.

#auth  sufficient     pam_ftp.so
auth     required       pam_unix2.so
auth     required       pam_shells.so
account  required       pam_unix2.so
password required       pam_unix2.so
session  required       pam_unix2.so

Jetzt meine Fragen:

Welche Einstellungen muss ich noch ändern, damit der neue Benutzer alle rechte wie ich als "root" bekommt und welches Verzeichniss muss ich dafür editieren ?

Wo kann ich die Adresse konfigurieren unter der mein Server per ftp im internet ereichbar ist?

Brauche ich um den Server übers Netz zu erreichen eine feste IP, oder geht das auch ohne ?

Wo kann ich einstellen, dass vsftpd beim bootvorgan bereits mitstartet.

Naja, wie ihr sichlich seht hab ich noch nicht all zu viel Plan von dem Ganzen.Hoffe ihr könnt mir bei meinen ersten Schritten behilflich sein.

Vielen Dank im Vorraus,
mfg R.S.
