打开proftpd.conf，在和段之间添加如下设置： Order allow,deny Deny from all 表示在incoming这个子目录下，从10.0.8这个网段登录的客户端有写入“WRITE”权限，其它人对该目录的写如权限都是被禁止的。如果要对所有的用户开放写入权限，只要把和之间的内容换成“Allowall“。 四、FTP服务器相关命令 1、ftpshut:关闭FTP服务，并在/etc下生成文件shutmsg。要重新开放FTP服务，把/etc/shutmsg删除。 2、ftpcout:FTP服务器在线人数信息显示。 3、ftpwho:FTP服务器在线人员名单。 附录：Proftpd.conf全文及解释 # This is a basic ProFTPD configuration file (rename it to # 'proftpd.conf' for actual use. It establishes a single server # and a single anonymous login. It assumes that you have a user/group # "nobody" and "ftp" for normal operation and anon. ServerName "MY REDHAT LINUX FTP" #设定FTP服务器的名称 ServerType standalone #设置FTP以Standalone模式运行，而不是以dameon模式 DefaultServer on #默认FTP服务器工作 # Port 21 is the standard FTP port. Port 21 #FTP服务默认占用的端口 # Umask 022 is a good standard umask to prevent new dirs and files # from beingsgroupsand world writable. Umask 022 #默认 RequireValidShell off #保证匿名用户正常登录，不要更改 ServerIdent off #不显示ftp服务器版本信息，以增强安全性 # To prevent DoS attacks, set the maximum number of child processes # to 30. If you need to allow more than 30 concurrent connections # at once, simply increase this value. Note that this ONLY works # in standalone mode, in inetd mode you should use an inetd server # that allows you to limit maximum number of processes per service # (such as xinetd) MaxInstances 30 # Set the user andsgroupsthat the server normally runs at. User nobody #设置FTP服务以nobody运行 Group nobody #注意：原来是“Group nobody”，一定要改为“Group nobody” # Normally, we want files to be overwriteable. AllowOverwrite on # A basic anonymous configuration, no upload directories.下面一段就是匿名服务的设置。 User ftp #匿名登录使用ftp用户 Group ftp #匿名登录使用ftp组 # We want clients to be able to login with "anonymous" as well as "ftp" UserAlias anonymous guest #给ftp用户anonymous的别名，使得anonymous登录就是ftp用户登录。 # Limit the maximum number of anonymous logins MaxClients 10 #最多10个匿名用户同时在线 # We want 'welcome.msg' displayed at login, and '.message' displayed # in each newly chdired directory. DisplayLogin welcome.msg #登录FTP显示的欢迎信息。放在FTP的根目录下。 DisplayFirstChdir .message # Limit WRITE everywhere in the anonymous chroot #说明看正文。 Order allow,deny Allow from 10.0.8. Deny from all |
