And for the FTP daemon, the file FTPD would be created.
对于ftp守护进程，会创建一个名为ftpd的文件。
The ftp daemon (ftpd), for example, could benefit from this capability.
例如，ftp守护进程 (ftpd)就可得益于此功能。
Where is the actual daemon, for example ftpd, and is the IP or hostname
其中，是实际的守护进程，例如ftpd， 是IP或主机名。
Now, if I parse it the FTPD daemon with an IP: 192.16.4.12, this is the result.
现在，如果我将它解析为IP为192.16.4.12的ftpd守护进程，结果如下。
The real_daemon informs wrappers where the real daemons live like FTPD, telnetd, and SSHD.
real_daemon通知wrappers实际的守护进程，如ftpd、telnetd和sshd在哪里。
Note that the "ftp stream tcp6 nowait root /usr/sbin/ftpd ftpd" entry is usually already present in the /etc/inetd.conf file.
注意，"ftpstream tcp6nowaitroot /usr/sbin/ftpd ftpd"项通常已经在 /etc/inetd.conf 文件中。
Otherwise, it would be required to input that passphrase every time the key gets used (which is impossible to accomplish when FTPD is using it).
否则，在每次使用密钥时，都会要求输入密码(在使用ftpd时这是不可能实现的)。
Fortunately, many FTP daemons, including the popular WU-FTPD allow the administrator to specify a range of ports which the FTP server will use.
幸运的是，许多FTP服务程序，包括最流行的WU - FTPD，管理员可以指定一定范围内的端口给服务器使用。
In the above output, tcpdmatch correctly states that access is denied, as there is no access rule for FTPD with clients that have an IP ending with 192.168.4.
在以上输出结果中，tcpdmatch正确说明拒绝访问，因为对IP以192.168.4结尾的客户端使用ftpd没有访问规则。
This in itself was interesting, because wu-ftpd had recently been heavily scrutinized after four CERT Advisories on wu-ftpd were issued between 1993 and 1995.
这本身就是非常有趣的，因为wu - ftpd近来已经在1993年和1995年之间提出的四个关于wu - ftpd的CERT建议后进行了大量地检查。
We simply replace the daemons that we wish to protect, in this case FTPD and telnetd with TCPD. So, after editing we would have the following configuration change.
我们只是替换想要保护的守护进程，本例中是用tcpd替换ftpd和telnetd。
