Question 1
What is the syntax to send 50 ICMP ECHO requests to the host labgw.tc4.space using the mtr
program?
Answer to question 1:
mtr –r -c 50 labgw.tc4.space
Question 2
On a Windows system, what is the option to renew the DHCP-assigned addresses for all of the
device’s network interfaces? Hint: Remember that for Windows the command switch (option),
may use a forward slash (/), instead of a rather than a hyphen (-)?
Answer to question 2:
Ipconfig /renew
Question 3
What is the syntax (on a Windows system) to show the network statistics about each packet
transmitted by a host, separated according to protocol type (IP, TCP, UDP, or ICMP) with a list
of routing table information? Hint: this command requires some hyphen (-) based options (also
called flags, or switches).
Answer to question 3:
Netstat -A

Answer to question 5:
Cat foo & > bar
Question 6
_________________ is an open source Network Forensic Analysis Tool (NFAT) for Windows
(but also works in Linux / Mac OS X / FreeBSD). This tool can be used as a passive network
sniffer/packet capturing tool in order to detect operating systems, sessions, hostnames, open
ports etc. without putting any traffic on the network. This tool can also parse PCAP files for off-
line analysis and to regenerate/reassemble transmitted files and certificates from PCAP files.
Answer to question 6:
Wireshark is the open source network forensic analysis tool
Question 7
What would be a Wireshark filter to search for FTP traffic with password attempts?
Answer to question 7:
ftp.request.command ==USER || ftp.request.command==PASS
