nslookup
A Linux command-line utility for displaying intermediary points (routers) an IP packet is passed through on its way to another network node is known as:
- nbtstat
- traceroute
- netstat
- tracert
traceroute
A network command-line utility in MS Windows that tracks and displays the route taken by an IP packet on its way to another host is called:
- ping
- traceroute
- dig
- tracert
tracert
Netstat is a command-line utility which can be used for:
- Displaying active TCP/IP connections
- Testing the reachability of a remote host
- Displaying intermediary points on the packet route
- Viewing the TCP/IP configuration details
Displaying active TCP/IP connections
A security technician was asked to configure a firewall so that the protected system would not send echo reply packets. What type of traffic should be blocked on the firewall to accomplish this task?
- SRTP
- ICMP
- CCMP
- SNMP
ICMP
A command-line utility used for checking the reachability of a remote network host is called:
- ping
- tracert
- dig
- netstat
ping
DOS command that sends an ICMP echo request message to a host. It’s used to check connectivity between 2 systems.
ping
A Windows command-line utility used to list the routers (or hops) a packet between two hosts. Can be used to determine the packet’s speed as well as verify that a path has not changed.
tracert
A troubleshooting command-line utility that displays statistics for active TCP/IP connections. Useful if you suspect a rogue computer connection.
netstat
A command-line protocol/packet analyzer. Administrators use it to capture packets; functions like a command-line version of Wireshark.
tcpdump
Utility that performs IP to MAC address resolution; used to determine what a given Layer 3 IP address correspond to (its Layer 2 MAC address). Can also be used to view and manipulate the ARP cache. It helps troubleshoot address resolution problems.
arp
A Windows tool used to query the DNS system to find the IP addresses for domain names, and vice versa
nslookup
Windows command used to view NIC network interfaces. It also displays the local IP address, subnet mask, the gateway address, and other network configuration of a computer. Additionally, it is used to refresh DHCP (Dynamic Host Configuration Protocol) and DNS (Domain Name System) settings.
ipconfig
A network-vulnerability scanner. scans ports, fingerprint systems, creates maps. Frequently used as a vulnerability scanner.
netcat
A Linux command-line utility used to follow the path a packet takes between two hosts and determine the packet’s speed
traceroute
A Linux tool used to query the DNS system to find the IP addresses for domain names, and vice versa.
dig
Linux command that shows the TCP/IP configuration and network interface settings. You can enable promiscuous mode on a NIC. Deprecated.
ifconfig
Linux command that is a preferred replacement for ifconfig command. Shows the TCP/IP configuration and network interface settings. You can enable promiscuous mode on a NIC.
ip
A network scanner that includes many capabilities, including identifying all the active hosts and their IP addresses in a network, the protocols and services running on each of these hosts, and the operating system of the host.
nmap
Graphical version of nmap.
Zenmap
