  為了驗證區域網網路安裝Linux,近兩天做了一個實驗,目的就是為了寫一個比較完整的帖子.
  約定:
  1.本帖操作環境是Redhat 9.0,VSFTPD的版本是Redhat 9.0所帶的vsftpd-1.1.3-8.i386.rpm,在安裝盤的第三張中
  2.VSFTPD實現的最基本的目的:用系統中存在的真實用戶能登入FTP,能用匿名訪問.
  3.伺服器的IP和和DNS設定
  第一塊網卡
  IP:192.168.0.1
  子掩碼:255.255.255.0
  網關不設置:
  第二塊網卡:
  IP:192.168.0.2
  子掩碼:255.255.255.0
  網關不設置
  因為我的操作環境是一個小型的區域網,其它的機器的IP都是在192.168.0這個網段上.ADSL是接在伺服器的第一個網卡上.伺服器的第二個網卡是接集線器,其它的客戶機都是接在集線器上.為了能讓ADSL訪問internet,因為自己手動設置了IP,DNS也要自己來設置,DNS如下:
  202.96.134.133
  202.96.168.68
  設置工具是:
  [root@linuxsir001 root]# redhat-config-network
  一.用VSFTP來架設FTP伺服器,VSFTP伺服器是目前最好的FTP伺服器軟體,優點是體積小,可定製強,效率高
  1.查看是否安裝了vsftpd軟體
  [root@linuxsir001 root]# rpm -qa | grep vsftpd
  如果沒有任何顯示,說明沒有把vsftpd安裝上,如果出現的是下面的這樣的提示,就證明已經安裝上了.
  [root@linuxsir001 root]# rpm -qa | grep vsftpd
  vsftpd-1.1.3-8
  我以Redhat 9.0,以其自帶的vsftpd包vsftpd-1.1.3-8版本來為本帖約定.
  [root@linuxsir001 root]# rpm -ivh vsftpd*.rpm
  2.打開VSFTP伺服器.
  [root@linuxsir001 root]# ntsysv
  把vsftpd伺服器打開,也就是在運行 ntsysv命令后,把vsftpd服務選中.
  [*] vsftpd
  3.運行/etc/init.d/vsftpd start
  [root@linuxsir001 root]# /etc/init.d/vsftpd start
  為 vsftpd 啟動 vsftpd: [ 確定 ]
  [root@linuxsir001 root]#
  4.配製VSFTP,FVSFTP的運行有兩種模式,一種是stardard "initd模式,另外一種是xinetd模式,上面我們所說的就是stardard initd運行模式.兩種模式運行機制不是相同的,stardard initd模式,適合專業FTP,且FTP總是一直有人訪問,佔用資源也是比較大,如果您的FTP總是有人訪問和登入.就要用這種模式.如果您的FTP訪問人數比較小,建議您用xinetd模式.xinetd模式,是當用戶請求時,vsftpd才會啟動.
  不同的環境,當然得用不同的啟動模式.
  如果想了解更多的,請在本帖後面跟帖,我會慢慢補充xinetd模式,以及虛擬用戶如何設置方面的問題.
  1]我們主要把vsftp的配製文件改一下就行了.配製文件在/etc/vsftpd/vsftpd.conf,用您喜歡的編輯器打開.請參考下面的配製文件.


  # 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]更改完配製文件后,我們可以用下面的命令來重啟VSFTPD伺服器
  [root@linuxsir001 root]# /etc/init.d/vsftpd restart
  關閉 vsftpd: [ 確定 ]
  為 vsftpd 啟動 vsftpd: [ 確定 ]
  [root@linuxsir001 root]#
  3]以匿名方式來訪問測試,在text模式下:
  注意:在text模式下,要用用戶名ftp,密碼ftp來訪問,這才是在text中匿名訪問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 with USER and PASS.
  KERBEROS_V4 rejected as an authentication type
  Name (192.168.0.1:root): ftp 這裡寫上ftp
  331 Please specify the password.
  Password:[這裡添寫ftp的密碼],匿名登入密碼也是ftp
  230 Login successful. Have fun.
  Remote system type is UNIX.
  Using binary mode to transfer files.
