I just started the chapter which is all about networking commands. Problem is the outputs are different than the ones I should be getting in the book. Oh well.
tracert or traceroute in linux traces the route to the remote device. Har har. More than that it lists every DNS and I.P. it takes to the receiver including the time it takes between hops.
ipconfig (ifconfig in linux) is something I used a lot before. Ifconfig lists everything about the current machines network configuration like it's I.P., DNS, default gateway, MAC addresses and all that good stuff.
ping. You know what that is. Yes you do. Ok fine I'll explain it. Ping just sends an ICMP packet to a host to make sure it's reachable. You can set different parameters like how many echo requests, force IPV6 yadda yadda.
More commands soon...
