Networking #1 Lab Journal - sullivaneg/TechJournal-SYS140 GitHub Wiki

Summary

In this lab we used Windows to learn bout some tools for working with networks. We ran these tools from the command-line. We used the tool ping to ping Champlain.edu. This gave us the IP address for the server we were pinging, and also how much time it took for us to communicate with that server. We then used nslookup to find the IP address for Champlain.edu and discovered that it was the same as the IP address we got from the ping tool. Then we used the tracert tool to see the path our network traffic took to reach UVM and compared it to the route that our traffic would have to take to reach the University of Kyiv. Unsurprisingly it took more steps for our traffic to reach the out of country university compared to the local university. Another tool we used was getmac. I learned that a MAC address is the permanent hardware address for a device, compared to IP address which is assigned to you by your network and can change. Then we used the hostname tool which shows us the name of the device we are on, then we compared that with the device name that is shown in the windows settings, they were the same. Then we used the netstat tool, which shows active TCP connections, ethernet info, IP info, etc. Then we connected to our ubuntu vm and saw that connection displayed with the netstat tool. Then we used the ipconfig tool to show TCP/IP config info and NCHP/DNS settings.

Reflection

This lab was interesting to me. I think networking is fascinating and its interesting to see how many stops our internet traffic makes before reaching us. This is also important from a cybersecurity perspective perhaps because you have to consider vulnerabilities for your traffic at every stop it makes. This lab went pretty smoothly for me.
