ICMP and ARP are two of the fundamental protocols used on our networks. In this video, you’ll learn about the “ping of death,” troubleshooting problems with an unreachable default gateway, and using ARP to troubleshoot issues.
You can gather many details about network performance from the command line, but only if you know the right commands. In this video, you’ll learn about netstat, ping, traceroute, nslookup, and much more.
Flaws in WEP encryption were exploited using a series of replays and very specific cryptographic attacks. In this video, you’ll learn the process that the bad guys used to break WEP encryption.
The address resolution protocol is one of the most fundamental protocols on our TCP/IP network. In this video, you’ll learn how to use the arp utility to view the results of a workstation arp.
Some network problems take a village. In this module, you’ll learn how to identify major network issues that will require an escalation to additional members of your team including switching loops, routing loops, route problems, proxy ARP configurations, and broadcast storms.
