I add a subdomain into file /etc/hosts:
0.0.0.0 localhost.lan group1.localhost.lan group2.localhost.lan
and then in the terminal:
I got the error msg:
ping: sendto: No route to host ping: sendto: No route to host Request timeout for icmp_seq 0
But in my another machine with
Fedora Linux 20, it can work well! I don't know what software I install in my linux let ping to work, or Mac OS has other rules?
Any advice will be welcome!
