问题: 网络不通,测试一下,出来一个!H,这玩意是个啥?
含义: After the trip time, some additional annotation can be printed: !H, !N, or !P (host, network or protocol unreachable), !S (source route failed), !F (fragmentation needed), !X (communication administratively prohibited), !V (host precedence violation), !C (precedence cutoff in effect), or !<num> (ICMP unreachable code <num>). If almost all the probes result in some kind of unreachable, traceroute will give up and exit.
行程结束后,可以打印一些附加注释:!H,!N,或!p(主机、网络或协议不可访问),!s(源路由失败),!F(需要碎片),!X(通信管理禁止),!v(主机优先级违例),!c(优先截止效果),或!<号码>(ICMP无法到达的代码<数字>)。如果几乎所有的探针都产生某种结果遥不可及,traceroute将放弃和退出。 |
