Question

Quizplus · Accepted Answer

Jack should use the nmap -sT 192.168.10.10 command to determine the services that are currently running on his Linux system. Key Takeaway: The nmap tool can be used to scan the open TCP and UDP ports on a system. It can also be used to test the firewall rules. It uses raw IP packets to determine the hosts on the network, the services running on these hosts, the OS version used by these hosts, and the firewalls used by these hosts. The nmap -sT command scans for open TCP ports and the nmap -sU command scans for open UDP ports.
