约定: 1。本帖操作环境是Redhat 9.0,vsFTPd的版本是Redhat 9.0所带的vsftpd-1.1.3-8.i386.rpm,在安装盘的第三张中 2。vsFTPd实现的最基本的目的:用系统中存在的真实用户能登入FTP,能用匿名访问。 3。本帖中vsFTPd运行模式是在standalone模式下运行的,也就是说,本帖中vsFTPd所有的功能都是在standalone模式下运行的。至于有些功能是否能在xinetd模式下运行,您就得测试了,不能照搬照抄。因为有些功能是必须运行在特定的模式下的。 3。服务器的IP和和DNS设定 第一块网卡 IP:192.168.0.1 子掩码:255.255.255.0 网关不设置: 第二块网卡: IP:192.168.0.2 子掩码:255.255.255.0 网关不设置 因为我的操作环境是一个小型的局域网,所以其它的机器的IP都是在192.168.0这个网段上。ADSL是接在服务器的第一个网卡上。服务器的第二个网卡是接集线器,其它的客户机都是接在集线器上。为了能让ADSL访问internet,因为自己手动设置了IP,所以DNS也要自己来设置,DNS如下: 202.96.134.133 202.96.168.68 设置工具是: [root@linuxsir001 root]# redhat-config-network 相应参考资料:vsFTPd官方文档: http://www.linuxsir.com/bbs/showthr...;threadid=43451 一。用vsFTPd来架设FTP服务器,vsFTPd服务器是目前最好的FTP服务器软件,优点是体积小,可定制强,效率高 1。查看是否安装了vsFTPd软件 [root@linuxsir001 root]# rpm -qa | grep vsftpd 如果没有任何显示,说明没有把vsFTPd安装上,如果出现的是下面的这样的提示,就证明已经安装上了。 [root@linuxsir001 root]# rpm -qa | grep vsftpd vsftpd-1.1.3-8 我以Redhat 9.0,以其自带的vsFTPd包vsftpd-1.1.3-8版本来为本帖约定。 [root@linuxsir001 root]# rpm -ivh vsftpd*.rpm 2。打开vsFTPd服务器。 [root@linuxsir001 root]# ntsysv 把vsftpd服务器打开,也就是在运行 ntsysv命令后,把vsftpd服务选中。 [*] vsftpd 3。运行/etc/init.d/vsftpd start [root@linuxsir001 root]# /etc/init.d/vsftpd start 为 vsftpd 启动 vsftpd: [ 确定 ] [root@linuxsir001 root]# 4。配制vsFTPd,vsFTPd的运行有两种模式,一种是standalone "initd"模式,另外一种是xinetd模式,上面我们所说的就是standalone "initd"运行模式。两种模式运行机制不是相同的,stardard initd模式,适合专业FTP,且FTP总是一直有人访问,占用资源也是比较大,如果您的FTP总是有人访问和登入。就要用这种模式。如果您的FTP访问人数比较小,建议您用xinetd模式。xinetd模式,是当用户请求时,vsFTPd才会启动。 不同的环境,当然得用不同的启动模式。 如果想了解更多的,请在本帖后面跟帖,我会慢慢补充xinetd模式,以及虚拟用户如何设置方面的问题。 1]我们主要把vsFTPd的配制文件改一下就行了。配制文件在/etc/vsftpd/vsftpd.conf,用您喜欢的编辑器打开。请参考下面的配制文件。 # Example config file /etc/vsftpd.conf # # The default compiled in settings are very paranoid. This sample file # loosens things up a bit, to make the ftp daemon more usable. # # Allow anonymous FTP? 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 2]更改完配制文件后,我们可以用下面的命令来重启vsFTPd服务器 [root@linuxsir001 root]# /etc/init.d/vsftpd restart 关闭 vsftpd: [ 确定 ] 为 vsftpd 启动 vsftpd: [ 确定 ] [root@linuxsir001 root]# 3]以匿名方式来访问测试,在text模式下: 注意:在text模式下,要用用户名ftp,密码ftp来访问,这才是在text中匿名访问FTP。看如下的操作: [root@linuxsir001 root]# ftp 192.168.0.1 Connected to 192.168.0.1. 220 (vsFTPd 1.1.3) 530 Please login with USER and PASS. 530 Please login |
