Which of the following port numbers could appear in the source port field of a TCP header leaving a requesting system?
A. 1022
B. 1023
C. 49172
D. 80
Homework Answers
C is correct. Source port numbers from a requesting machine are dynamic and must not be from the well-known port range 0–1023.
A, B, and D are incorrect. All these answers are from the well-known port range, which cannot be used here.

ND-OF-CHAPTER QUESTIONS Thought Questions 1. How do you think TCP would handle the problem if an acknowledgment were lost, so that the sender retrans- mitted the unacknowledged TCP seg- ment, therefore causing the receiving transport process to receive the same segment twice? 2-2. a) Compute the minimum number of TCP segments required to open a con- nection, send an HTTP request and response message, and close the con- nection. Justify this number by creating a table showing each message and...

Hosts A and B are communicating over a TCP connection, and Host B has already received from A all bytes up to and including byte 1029. Suppose Host A then sends three segments to Host B back-to-back. The first, second and third segments contain 1200, 150 and 80 bytes of data respectively. In the first segment, the sequence number is 1060, the source port number is 8080, and the destination port number is 80. Host B sends an acknowledgment whenever...

1a) Which of the following statements is true?
Running SSH on the Telnet port will now be sent across an
unencrypted port.
Despite the results of the scan, the service running on port 23
is actually Telnet and not SSH, and creates an additional
vulnerability
Running SSH on port 23 provides little additional security from
running it on the standard port.
Remote SSH connections will automatically default to the
standard SSH port.
The use of OpenSSH on its default secure...
