Ripristinare vsftp

Ciao a tutti,

Dopo i recenti disagi con le picon (poi rimosse completamente) sono riuscito a far ripartire il sistema che ad ogni riavvio si bloccava sulla schermata "booting" o "starting gui".
Fortunatamente il telecomando funzionava e ho avuto accesso al menù, sperando di poter far ripartire tutto con un backup salvato precedentemente. Di feedback da parte del sistema che questo sia accaduto non ne ho avuto neanche uno, ne con il plugin autobackup (che non ho impostato in automatico) ne con lo strumento backup stock e dire che li uso entrambe per essere sicuro di avere sempre un paio di salvagenti diversi..

Aggiungo che l'unico flash drive montato (da 4gb) è tutto per gli universi, quindi, se non ho capito male questo è il problema delle picon che mi fanno saltare il sistema.
Avevo provato a fare due partizioni /universe e /media/usb/ ma in questo modo non funziona....

Comunque non so come sia successo ma dopo qualche riavvio sembra tornato tutto alla normalità, dico sembra perchè non parte più VSFTP, neanche andando nel relativo menù ad abilitarlo...
Volevo tentare via telnet ma non so in che percorso sia il binario...
Che posso fare?
 
Ok, lanciando da terminale

Code:
vsftpd

Posso accedere con Filezilla e fare tutto.
Non riesco però a riavviare o stoppare il servizio...
e non capisco: è inet.d a lanciare il servizio all'avvio (credo di si) oppure no?
 
Ok, risolto mettendo su inetd.conf la seguente riga:

Code:
ftp stream tcp nowait root /usr/sbin/vsftpd

e configurato vsftpd.conf in questo modo:

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
listen=NO

# No PAM sessions to save resources
session_support=NO

# 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=NO
#
# Make sure PORT transfer connections originate from port 20 (ftp-data).
connect_from_port_20=NO
#
# 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=ftp
#
# 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 blah 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_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
#
# This string is the name of the PAM service vsftpd will use.
pam_service_name=vsftpd
#
# This option is examined if userlist_enable is activated. If you set this
# setting to NO, then users will be denied login  unless  they are  explicitly 
# listed  in the file specified by userlist_file.  When login is denied, the 
# denial is issued before the user is asked for a password.
userlist_deny=YES
#
# If enabled, vsftpd will load a list of usernames, from the filename given by
# userlist_file.  If a user tries to log in using  a  name in  this  file,  they
# will be denied before they are asked for a password. This may be useful in 
# preventing cleartext passwords being transmitted. See also userlist_deny.
userlist_enable=NO
#
# 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
#
# If set to YES, local users will be (by default) placed in a chroot() jail in
# their home directory after login.  Warning: This  option has  security  
# implications,  especially  if  the users have upload permission, or shell access.
# Only enable if you know what you are doing.  Note that these security implications
# are not vsftpd specific. They apply to all FTP daemons which offer to put 
# local  users in chroot() jails.
chroot_local_user=No
#
allow_writeable_chroot=YES
#
tcp_wrappers=NO
#
local_root=/

Anche se ho qualche perplessità in merito alla sicurezza visto che non ho compreso benissimo alcune voci...
