Network Diagnosis

Knowing simultaneously these three things for failing and working circumstances would be quite useful.

ifconfig to show ip address;
route to show which gateways or directly routes would be used(netstat -rn for osx);
traceroute to show what devices are being traversed;

Add a route,

# osx
route -n add 10.0.0.0/24 10.0.0.1
# linux
route -n add -net 10.0.0.0/24 gw 10.0.0.1
