IP未列入白名单时，FTPS将失败

那么，经过与Azure支持团队的广泛交stream，似乎pure-ftpd就是问题所在。 根本没有注意到几个指令，包括它应该使用哪个被动端口。 我再次用vsftpd重新整理了一下，似乎已经奏效了。 就目前而言，我已经放弃了虚拟用户，为了时间的缘故。 以下是我所做的：

本指南介绍如何让vsftpd只根据特定的用户进行chroot操作。

sudo apt-get install vsftpd ftp

vi /etc/vsftpd.conf

 # 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 pasv_enable=YES pasv_min_port=13000 pasv_max_port=13100 port_enable=YES pasv_address=EXTERNAL IP of your server pasv_addr_resolve=NO # # This directive enables listening on IPv6 sockets. By default, listening # on the IPv6 "any" address (::) will accept connections from both IPv6 # and IPv4 clients. It is not necessary to listen on *both* IPv4 and IPv6 # sockets. If you want that (perhaps because you want to listen on specific # addresses) then you must run two copies of vsftpd with two configuration # files. listen_ipv6=NO # # Allow anonymous FTP? (Disabled by default). 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 # # 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 allow_writeable_chroot=YES # # 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 # rsa_private_key_file=/etc/ssl/private/ssl-cert-snakeoil.key rsa_cert_file=/etc/pki/tls/certs/cert.pem rsa_private_key_file=/etc/pki/tls/certs/key.pem ssl_enable=YES #force_local_data_ssl=YES force_local_logins_ssl=YES #ssl_sslv3=YES # # Uncomment this to indicate that vsftpd use a utf8 filesystem. #utf8_filesystem=YES 

—结束内容—

请注意，您需要在此更改服务器的外部IP的IP地址

sudo su

mkdir -p / etc / pki / tls / certs / cd / etc / pki / tls / certs /

openssl req -newkey rsa：2048 -new -nodes -x509 -days 3650 -keyout key.pem -out cert.pem

确保为服务器指定了正确的FQDN。

chown 600 *

添加你的ftp用户：

添加用户

usermod -s / bin / false

vi / etc / shells

添加/ bin / false作为最后一行，如果它不在文件中

cd / home

修改目录，以便在必要时写入目录

确保你已经允许在该服务器（服务器和azure色）的防火墙端口13000-13100（或任何你select的范围）

sudo vi /etc/vsftpd.chroot_list

在那里，每行input一个需要被chroot的用户

服务vsftpd重启

服务vsftpd状态##确保所有运行正常

我希望这可以帮助别人。 我在第一次通过工作后logging了这一点，然后将其应用到需要它的第二台服务器上，并运行。
