vsftpd.conf配置详解，vsftpd.conf详解

根据 /etc/vsftpd/vsftpd.conf默认配置给出设定功能   # Example config file /etc/vsftpd/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 允许匿名用户登录 # Uncomment this to allow local users to log in. local_enable=YES 允许系统用户名登录 # Uncomment this to enable any form of FTP write command. write_enable=YES 允许使用任何可以修改文件系统的FTP的指令 # 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 本地用户新增档案的权限 # 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 允许匿名用户上传文件 # Uncomment this if you want the anonymous FTP user to be able to create # new directories. #anon_mkdir_write_enable=YES 允许匿名用户创建新目录 # Activate directory messages - messages given to remote users when they # go into a certain directory. dirmessage_enable=YES 允许为目录配置显示信息,显示每个目录下面的message_file文件的内容 # Activate logging of uploads/downloads. xferlog_enable=YES 开启日记功能  # Make sure PORT transfer connections originate from port 20 (ftp-data). connect_from_port_20=YES 使用标准的20端口来连接ftp  # 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 所有匿名上传的文件的所属用户将会被更改成chown_username  #chown_username=whoever  匿名上传文件所属用户名  # You may override where the log file goes if you like. The default is shown # below. #xferlog_file=/var/log/vsftpd.log 日志文件位置  # If you want, you can have your log file in standard ftpd xferlog format xferlog_std_format=YES 使用标准格式  # You may change the default value for timing out an idle session. #idle_session_timeout=600 空闲连接超时  # You may change the default value for timing out a data connection. #data_connection_timeout=120 数据传输超时  # 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 当服务器运行于最底层时使用的用户名  # 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 允许使用\"async ABOR\"命令,一般不用,容易出问题  # 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  管控是否可用ASCII 模式上传。默认值为NO #ascii_download_enable=YES 管控是否可用ASCII 模式下载。默认值为NO # You may fully customise the login banner string: #ftpd_banner=Welcome to blah FTP service.   login时显示欢迎信息.如果设置了banner_file则此设置无效  # You may specify a file of disallowed anonymous e-mail addresses. Apparently # useful for combatting certain DoS attacks. #deny_email_enable=YES  如果匿名用户需要密码,那么使用banned_email_file里面的电子邮件地址的用户不能登录 # (default follows) #banned_email_file=/etc/vsftpd/banned_emails 禁止使用匿名用户登陆时作为密码的电子邮件地址  # 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 如果启动这项功能，则所有列在chroot_list_file中的使用者不能更改根目录  # (default follows) #chroot_list_file=/etc/vsftpd/chroot_list 定义不能更改用户主目录的文件  # 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    是否能使用ls -R命令以防止浪费大量的服务器资源  # When "listen" directive is enabled, vsftpd runs in standalone mode and # listens on IPv4 sockets. This directive cannot be used in conjunction # with the listen_ipv6 directive. listen=YES  绑定到listen_port指定的端口,既然都绑定了也就是每时都开着的,就是那个什么 standalone模式  # This directive enables listening on IPv6 sockets. To listen on IPv4 and IPv6 # sockets, you must run two copies of vsftpd whith two configuration files. # Make sure, that one of the listen options is commented !! #listen_ipv6=YES   pam_service_name=vsftpd   定义PAM 所使用的名称，预设为vsftpd userlist_enable=YES  若启用此选项,userlist_deny选项才被启动  tcp_wrappers=YES   开启tcp_wrappers支持      过滤掉那些注释，以便我们日后修改配置，大家可以删除vsftpd.conf内容，拷贝以下：   anonymous_enable=YES local_enable=YES write_enable=YES local_umask=022 #anon_upload_enable=YES #anon_mkdir_write_enable=YES dirmessage_enable=YES xferlog_enable=YES connect_from_port_20=YES #chown_uploads=YES #chown_username=whoever #xferlog_file=/var/log/vsftpd.log xferlog_std_format=YES #idle_session_timeout=600 #data_connection_timeout=120 #nopriv_user=ftpsecure #async_abor_enable=YES #ascii_upload_enable=YES #ascii_download_enable=YES #ftpd_banner=Welcome to blah FTP service. #deny_email_enable=YES #banned_email_file=/etc/vsftpd/banned_emails #chroot_list_enable=YES #chroot_list_file=/etc/vsftpd/chroot_list #ls_recurse_enable=YES listen=YES #listen_ipv6=YES pam_service_name=vsftpd userlist_enable=YES tcp_wrappers=YES
