New York City College of Technology/CUNY Department of Computer Systems Technology CST2405 – System Administration – Fall 2020 Name: Vasyl Yakovishak Date: 09/12/2020 Two tools that are indispensable when testing TCP/IP network connectivity are ping and tracert. The ping utility is available on Windows, and tests network connectivity. The tracert utility is available on Windows. In addition to testing for connectivity, tracert can be used to check for network latency. For example, when a web browser fails to connect to a web server, the problem can be anywhere between client and the server. A network admin may use the ping command to test for local network connectivity or connections where there are few devices. In a complex network, the tracert command would be used. Task 1: Use the ping Command to Verify Simple TCP/IP Network Connectivity. The ping command is used to verify TCP/IP Network layer connectivity on the local host computer or another device in the network. The command can be used with a destination IP address or qualified name, such as eagle-server.example.com, to test domain name services (DNS) functionality. For this lab, only IP addresses will be used. Step 1: Verify TCP/IP Network layer connectivity on the local host computer. 1. Open a Windows Command Prompt and determine IP address of the local host computer with the Ipconfig command. C:\> ipconfig 2. Record information about local TCP/IP network information: TCP/IP Information Value IP Address 192.168.2.6 Subnet Mask 255.255.255.0 Default Gateway 192.168.1.1 3. Use the ping command to verify TCP/IP Network layer connectivity on the local host computer IP : c:\> ping xxx.xxx.xxx.xxx ( local host computer IP) Field Value Size of packet 32 Number of packets sent 4 Number of replies 4 Number of lost packets 0 Minimum delay 0 Maximum delay 0 Average delay 0 Page 1 of 3

Use the ping command to verify TCP/IP Network layer connectivity to the default gateway. 2. Fill in the results of the ping command to the default Gateway: Field Value Size of packet 32 Number of packets sent 4 Number of replies 4 Number of lost packets 0 Minimum delay 0 Maximum delay 0 Average delay 0 Question: What would be the result of a loss of connectivity to the default gateway? -------------------------------------------------------------------------------------------------------------- Task 2: Use the tracert Command to Verify TCP/IP Connectivity. The tracert command is useful for learning about network latency and path information. Instead of using the ping command to test connectivity of each device to the destination, one by one, the tracert command can be used. Step 1: Verify TCP/IP Network layer connectivity with the tracert command. 1. Open a Windows terminal and issue the following command: C:\> tracert 10.10.210.240 2. Record your result in the following table: Field Value Maximum number of hops 30 First router IP address 192.168.1.1 Second router IP address 10.10.210.40 Destination reached 10.10.210.40 Question: What is the d ifference between tracert and ping? Tracert is showing you route how to reach a server and time by showing you how many hops Ping is a quick test to see if server is reachable and how long it would take to send and receive data -------------------------------------------------------------------------------------------------------------- Page 2 of 3
New York City College of Technology/CUNY Department of Computer Systems Technology CST2405 – System Administration – Fall 2020 What are the basic network commands below used for? Open Windows Powershell to complete. 1. Getmac - command outputs a list of all network adapters and their MAC addresses. 2. arp -a – Display IP and Physical addresses 3. route print – Display IPv4 Route Table, Interface list, Persistent Routes, IPv6 Route Table and Active Route. 4. net use - Display network drives 5. Net user – Dispay a user account 6. Gpupdate /force – Gpupdate will update only group policy and by adding /force it would update all settings 7. Ipconfig /displaydns – DNS Cashes 8. Get-Date – display a date and time 9. Get-Help - Display information about powersell and how to use get-help commands 10. Get-History – Display a history of commands that was typed during a session 11. Get-Location - Get and display the current location 12. Get-Process – Display a processes that is running 13. Get-Credential Display username and password 14. Get-Host – display a a computer that hosting 15. Test-Connection – Testing a connection to removed computer Page 3 of 3
