Hi Hackers, I'm a DevOps but I feel limited in understand abou t networking. I can do tcpdump, wireshack , iptables etc. But other than that, I falled short. I don't exactly know how a packet get route, what is bgp. what is the output of tracroute mean...how Linux network stack really work...what is the virtual interface...what is the arp cache table...what is TIMEOUT TIMEOUT_WAIT... I hope I can find some good books to dive deep and understand fundamental of networks and fill up this hole in my knowledges.
