要根据TTL(Time-To-Live,生存时间)值判断操作系统类型,我们首先需要了解不同操作系统默认的TTL值范围。通常,这些值可以作为基准来判断目标系统可能运行的操作系统。以下是一个大致的TTL值范围对应不同操作系统的参考: Windows: TTL值通常是128 Linux/Unix: TTL值通常是64 Mac OS: TTL值也通常是64 请注意,这些值...
TTl值确定操作系统（TTl value determines the operating system）WINDOWS 98 TTL: 32 2.2 X / 2.4 X LINU TTL: 64 WINDOWS NT / 2000 / XP TTL: 2000 UNIX/BSD TTL: 255 Because in the process of packet transmission, routing, every TTL value minus 1 automatically, so it is an approximate ...

TTL Values The operating system sets the initial TTL value or application creating the IP packet. Here are some common default TTL values: Linux/MAC OS– 64 Windows– 128 Cisco Routers– 255 DNS– depends on the DNS resolver (can range from 128 to 86400) Setting higher TTL values allows p...
ICMP 回显应答的 TTL 字段值为 128 这样,我们就可以通过这种方法来辨别操作系统 TTL值的注册表位置HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Tcpip\Parameters 其中有个DefaultTTL的DWORD值,其数据就是默认的TTL值了,我们可以修改,但不能大于十进制的255。

By default, TTL of the ICMP echo replies is 255 from Cisco router, and 128 from Windows-OS , and only 64 from Linux OS. and each router hop will decrease TTL Value by 1. This is actually helpful for network/security analysts to understand which Operating system is running on remote ...
