我们在机房选择、測试网络的质量的时候，往往仅仅依据跳数、延迟、抖动、网络吞吐量等指标来衡量，非常多时候跳数并不能全然显示网络拓扑优劣，于是写了个traceroute结合whois的小脚本来直观显示每一跳所处的网络位置。


须要安装mtr和whois


脚本：

[root@localhost ~]# more  geotrace.sh         

#!/bin/bash
echo traceroute ip:$1 from localhost
ip=$1
echo
#mtr --n --report $ip|grep -v ^HOST|awk '{printf $1" "$2" ";system("whois "$2"|grep descr|head -n1|cut -c17-");printf "\n"}'
mtr --n --report $ip|grep -v ^HOST|awk '{printf $1" "$2" ";system("whois "$2"|grep -e netname -e descr|cut -c17-");printf "\n"}
'


測试结果还挺令人惬意：

[root@localhost ~]# ./geotrace.sh 8.8.8.8

traceroute ip:8.8.8.8 from localhost
