第3题:

TTL是什么?有什么用处,通常那些工具会用到它?(ping? traceroute? ifconfig? netstat?)


正确答案:

 

简:TTL是Time To Live,一般是hup count,每经过一个路由就会被减去一,如果它变成0,包会被丢掉。它的主要目的是防止包在有回路的网络上死转,浪费网络资源。ping和traceroute用到它。
详:TTL是Time To Live,目前是hup count,当包每经过一个路由器它就会被减去一,如果它变成0,路由器就会把包丢掉。IP网络往往带有环(loop),比如子网A和子网B有两个路由器相连,它就是一个loop。TTL的主要目的是防止包在有回路的网络上死转,因为包的TTL最终后变成0而使得此包从网上消失(此时往往路由器会送一个ICMP包回来,traceroute就是根据这个做的)。ping会送包出去,所以里面有它,但是ping不一定非要不可它。traceroute则是完全因为有它才能成的。ifconfig是用来配置网卡的,netstat -rn 是用来列路由表的,所以都用不着它
