[j3nda]

ok jdu se na to napred vyspat, diky - je mi jasny, ze te unavuje zodpovidat stupidni dotazy, jestli se mi to podari vygooglit a rozjet, pisnu sem reseni

[jj_sk]

naco chces instalovat vsftp, ked tam nainstalovany je?
....

ani som netusil aky tam je ftp server, ale ani som po tom nepatral, o to to ma j3nda lahsie

monkus: (jedna rada za den)/(jeden clovek) postacuje, inac nie je ziadna vlastna iniciativa

[monkus]

nie, skor je to o tom, ze niekomu step-by-step nieco napisat, znamena otestovat to. a kedze nemam momentalne cas, treba pouzit google. treba verit, ze rovnaky problem malo uz desiatka inych ludi...

[j3nda]

chapu a obema Vam dekuju za rady

nasel jsem okomentovanej konfigurak vsftpd a ten mi lecos ozrejmil, co se tyce toho chrootovani, tak uz je mi celkem jasno a skutecne staci pridat tech par radku jak mi radil jj_SK, ten problem s prihlasovanim jsem hledal a podle vseho by to melo byt pravy k adresari, to budu muset doma jeste otestovat. navodu jak na to jsem nasel nekolik a kazdej je jinej
jeste jsem se chtel zeptat jj_SK jak si to myslel s tim zakazanim shellu? predpokladam, ze je to z duvodu, aby nemohli obchazet ten chroot, ale jak ho vypnout jsem nenasel

jinak prikladam ten okomentovanej configurak, treba to nekomu pomuze:

# 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.
#
# Allow anonymous FTP? (Beware - allowed by default if you comment this out).
anonymous_enable=YES
#
# 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 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

pam_service_name=vsftpd
userlist_enable=YES
#enable for standalone mode
listen=YES
tcp_wrappers=YES

vypnutie shellu je koli tomu, aby sa mohol ftpckovat, ale aby sa nemohol telnetnut / sshcknut. zvykne sa zmenit shell na /bin/nologin /bin/noshell ...

[zbyneksk]

detto zadaj do vyhladavaca "500 OOPS : vsftpd: refusing to run with writable anonymous root" a uvidis, kolko ludi zrazu malo rovnaky problem :-)

Výsledky 1 - 10 z asi 2 640 na dotaz "500 OOPS : vsftpd: refusing to run with writable anonymous root".

[monkus]

vies mi dat connect na tvoj azbox? do 5 minut to bude opravene :-)

[monkus]

postup je nasledovny

1. editovat vsftpd.conf, pridal som tam len toto
chroot_local_user=YES

2. restart ftp (najlepsie cez OSD)

3. vytvorenie uzivatela
MMP[etc]$ adduser -h /PLUGINS/home/monkus -s /bin/sh monkus
Changing password for monkus
Enter the new password (minimum of 5, maximum of 8 characters)
Please use a combination of upper and lower case letters and numbers.
Enter new password:
Re-enter new password:
Password changed.

4. vytvorenie suboru v homeadresari, aby sme vedeli, ze kde sme
MMP[etc]$ touch /PLUGINS/home/monkus/TOTO_JE_MOJ_HOMEDIR

5. test pripojenia a kontorla, kde ma to vobec pusti
monkus@notbug:~$ ftp azbox
Connected to azbox.

vsetko funguje ako ma.
ty mas imho problem v pravach homediru uzivatela, skus si to skontrolovat.

[j3nda]

super dik za navod, ja se s tim tu uz nakou dobu morim, problem bude asi v tom, ze vsftp je chrootovany do adresare plugins, zatimco me se vytvorila homedir uzivatele v home adresari v korenovem adresari

zacal jsem podle tveho navodu, zeditoval vsftpd.conf, ale nejde mi tam prehrat, read only file system, ani zmenit atributy mi nejdou

zatim nade mnou linux vyhrava

[monkus]

mount -o remount,rw /dev/hda1 /MMP

a znova a znova

[j3nda]

moc dekuji za pomoc - funguje to
slava monkusovi
ted teda jeste zakazat ten shell
pri tvorbe uzivatele tam teda mam dat nakonec /bin/noshell ?

koukam, ze je ale zachrootovanej i root, takze bych tam mel dat spis toto, ze?

# 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

a do nej dat root

[monkus]

ano

[monkus]

alebo len zmenit v subore /etc/passwd

[j3nda]

jeste jednou diky

[j3nda]

slozku s FTP jsem tedy nasmeroval do /DATA/hdb1/ftp aby se to nezapisovalo na flasku, vsftpd.conf jsem upravil takto:

anonymous_enable=YES
local_enable=YES
write_enable=YES
local_umask=022
dirmessage_enable=YES
xferlog_enable=NO
connect_from_port_20=YES
xferlog_std_format=YES
listen=YES
pam_service_name=vsftpd
#tcp_wrappers=YES
ftp_username=root
secure_chroot_dir=/DATA/hdb1/ftp
chroot_list_enable=YES
chroot_list_file=/MMP/etc/vsftpd.chroot_list

a do chroot_listu:
root

ale mam nadale zamcenyho do slozky i roota, jinak to beha pekne
