عدم لاگین به ftp sever ( حل شد )
« : 06 آبان 1392، 08:36 ب‌ظ »
سلام
من یه ftp server با vsftpd راه انداختم . این محتویات فایل پیکره بندی هست .
# 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?  vsftpd can run either from an inetd or as a standalone
# daemon started from an initscript.
listen=YES
#
# Run standalone with IPv6?
# Like the listen parameter, except vsftpd will listen on an IPv6 socket
# instead of an IPv4 one. This parameter and the listen parameter are mutually
# exclusive.
#listen_ipv6=YES
#
# Allow anonymous FTP? (Disabled by default)
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
#
# 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
#
# 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.
# Note that the default log file location is /var/log/xferlog in this case.
#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 on some FTP servers, ASCII support allows a denial of service
# attack (DoS) via the command "SIZE /big/file" in ASCII mode. vsftpd
# predicted this attack and has always been safe, reporting the size of the
# raw file.
# ASCII mangling is a horrible feature of the protocol.
#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 restrict local users to their home directories.  See the FAQ for
# the possible risks in this before using chroot_local_user or
# chroot_list_enable below.
#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().
# (Warning! chroot'ing can be very dangerous. If using chroot, make sure that
# the user does not have write access to the top level directory within the
# chroot)
#chroot_local_user=YES
#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
#
# Customization
#
# Some of vsftpd's settings don't fit the filesystem layout by
# default.
#
# This option should be the name of a directory which is empty.  Also, the
# directory should not be writable by the ftp user. This directory is used
# as a secure chroot() jail at times vsftpd does not require filesystem
# access.
#secure_chroot_dir=/var/run/vsftpd/empty
#
# This string is the name of the PAM service vsftpd will use.
pam_service_name=vsftpd
#
# This option specifies the location of the RSA certificate to use for SSL
# encrypted connections.
rsa_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
# This option specifies the location of the RSA key to use for SSL
# encrypted connections.
rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
anon_root=/home/behrooz/ftp

میخوام به صورت anonymous لاگین کنم . اما ازم یوزر و پسورد میخواد . در صورتی که من در فایل پیکره بندی گزینه anonymous_enable=YES را فعال کردم .

سلام مجدد
تونستم مشکل را حل کنم . اما حالا یه مشکل جدید دارم . من vsftpd را برای کاربر anonymous تنظیم کردم . الان داخل ویندوز که با دستور
ftp://192.168.56.101میتونم متصل بشم . اما باز هم ازم نام کاربری می‌خواد . مگر نه اینکه فلسفه کاربر anonymous اینکه که بدون نام کاربری و رمز به ftp server وصل بشه . این یه مورد بود . اما مورد اصلی
در بالا گفتم که داخل کامند لاین ویندوز به راحتی میتونم وصل بشم . اما وقتی ادرس بالا را در اینترنت اکسپلورر یا ویندوز اکسپلورر اجرا میکنم نمیتونم وصل بشم و یه ارور در یافت میکنم . تصویر ارور را ضمیمه کردم .

اگر از داخل cmd وصل میشه از تو اینترنت اکسپلورر هم باید وصل بشه . مگر این که اینترنت اکسپلورر قلقی داشته باشه که من خبر نداشته باشم .

برای اون نام کاربری که میپرسه شما نام کاربری رو anonymous وارد کن بعد اوکی بزن اگر دوباره نام کاربری پرسید دوباره هم اوکی بزن وارد میشه.
نرم افزارهای  ftp چون خودشون اوتومات نام کاربری anonymous رو وارد میکنن برای همین متوجه نمیشیم.
برای این که نام کاربری نپرسه این شکلی تو مرور گر بزنین که نام کاربری نپرسه
ftp:anonymous@192.64.8.35

شاید ftp server های دیگه بهتر باشن . مثلا الان vsftpd به کاربر anonymous اجازه write رو نمیده . متن زیر رپ بخونین در مورد ftp سرورای دیگه نوشته :

Selecting an FTP Server

FTP is an old protocol, and numerous implementations of it have sprung up over the years. These servers vary in many details; however, they all serve the same protocol, and they all look very much alike to their users. FTP server options for Linux include the following:

Pure-FTPd This server, headquartered at http://www.pureftpd.org, is an FTP server that emphasizes security. Many distributions ship with it, typically under the package name pure-ftpd.

vsftpd This server aims to excel at security, stability, and speed. In doing so, its developers have chosen to eschew some of the more advanced features of servers such as ProFTPd. If you don’t need those features, this trade-off may be more than acceptable. You can learn more from its Web site, http://vsftpd.beasts.org. It’s available with a growing number of Linux distributions, usually with the package name vsftpd.

ProFTPd This server, headquartered at http://proftpd.org, is one of the more popular of the very complex FTP servers. It ships with most major Linux distributions. Its configuration file is modeled after that of Apache, and the server supports many advanced features. It is accordingly much harder to configure.

This list of FTP servers is far from complete. Gentoo Linux, which has a fairly complete software repository, has at least seven distinct FTP servers. Many more very obscure servers are available. If you have special needs, you might want to investigate some of these alternatives.

Because FTP can potentially provide users with substantial access to the system—the ability to read or write any file, within limits imposed by Linux file ownership and permissions—FTP servers are unusually sensitive from a security point of view. As a result, the Web pages for many FTP servers emphasize their developers’ attention to security. Most FTP servers provide explicit support for locking themselves in chroot jails, as described with reference to DNS servers in Chapter 6, “DNS Server Configuration.”

For a small FTP site, chances are any of the servers in the preceding list will work well. Because they both ship with multiple Linux distributions, the next two sections focus on Pure-FTPd and vsftpd.

مشکل را حل کردم . بایستی تیک داخل قسمت use passive ftp  برمیداشتم . الان راحت هم با اینترنت اکسپلورر و هم ویندوز اکسپلورر میتونم به عنوان کاربر anonymous لاگین کنم .
