The commonly used network commands ping and traceroute both utilize TTL. When using the traceroute command, a stream of packets with increasingly higher sequential TTLs are sent across the Internet towards a destination. Because each step along the connection is the last stop for one of the pac...

TTL是生存时间的意思,就是说这个ping的数据包能在网络上存在多少时间。 一般Linux系统的TTL值为64或255,Windows NT/2000/XP系统的默认TTL值为128,Win7系统的TTL值是128,Windows 98系统的TTL值为32,UNIX主机的TTL值为255。 由于黑客在入侵前都会探测操作系统的TTL值,因此我们可以通过修改TTL值让别人不清楚我安装...
