Mac安装MTR

通过brew安装

brew install mtr

安装目录一般为

/usr/local/sbin/mtr
/usr/local/sbin/mtr-packet

之前敲mtr会

mtr: command not found

创建软链接

ln -s /usr/local/sbin/mtr /usr/local/bin/mtr 
ln -s /usr/local/sbin/mtr-packet /usr/local/bin/mtr-packet

mtr需要root权限执行

host:sbin user$ mtr
mtr-packet: Failure to open IPv4 sockets
mtr-packet: Failure to open IPv6 sockets
mtr: Failure to start mtr-packet: Invalid argument

执行

sudo mtr baidu.com
