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。
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。
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。
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。
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)。
