Brendan Burke
18:15
ye
Thomas Kehoe
18:16
yes
Catherine Rogers
18:16
yup
Josh Laney
18:59
what will be the format and logistics of the exam?
Grady Roberts
19:03
what sections will the exam cover?
Ryan Ritzo
19:05
how will exam work now that we will be taking it online?
Catherine Rogers
19:11
is there a topic list?
Matthew Bain
19:21
What should we focus on most?
Jake Moses
19:33
Will the test be the same format as last time, will it be open or closed note?

19:37
Differences between UDP vs TCP
Sonia
19:40
Can you go over flow control for TCP and the problems with it?
Matthew Bain
20:14
can you go over the RTP algorithm again
Andrea Zhang
20:42
what’s wireshark analysis?
Dirty Dan
21:53
Last exam we had several computational style questions such as doing bit division to determine whether a packet was corrupted. Will we see those same style questions on this exam and if so can you provide some examples of items of this style? It seems like most of the transport layer material is concept base.
Matthew Bain
22:19
will each question be weighted the same?
Matthew Bain
23:18
How long is it designed to be?
Dirty Dan
25:52
For the coding question, are you looking for actual compilable code use the socket library or is it more pseudocode and hitting my concepts and steps?
Matthew Bain
26:02
can you give us an example question?
Nathan Hunter
27:02
What if we don't have 5+ hours to set aside on Thursday
Jessica Krynitsky
27:18
You said 4-5 questions on wireshark analysis and 1 coding, what will the remainder be like?
Matthew Bain
27:29
^
Sonia
27:48
Can you talk about what is involved with the HTTP protocol
Jake Moses
28:25
When you say socket programming do you mean more of the email spoofer assignment or more of the implementation of the TCP protocol?
Seth Dolin
28:32
What language will the coding question be in?
Matthew Bain
41:11
Belf?
Grady Roberts
41:51
Amount of buffer space left
Alex Kim

01:03:34
Do we need to use the Metasploitable3 Virtual Machine for the exam?
Matthew Bain
01:03:38
can you go over things that you think we missed while asking
Mesgana Dinare
01:04:01
for the coding question is there going to be template code/comments like on the email spoofer or just an empty file?
Kwadwo Tenkorang
01:04:04
Can you describe the 3 way handshake
Sonia
01:05:17
^^
Catherine Rogers
01:09:12
Can you talk about the multiplexing and demultiplexing again?
Jack Schefer
01:16:26
so for UDP you only use Destination IP+Port but for TCP you have both Souce IP+port and Destination IP+Port?
Jack Mcmanus
01:17:40
Thank you!
Matthew Bain
01:17:50
see ya good luck peeps
Nathan Hunter
01:17:51
Still unsure what our socket program would look like without a template to work from
Dirty Dan
01:17:52
Thank you!
Matthew Bain
01:18:11
yes
Jack Mcmanus
01:24:32

Grady Roberts
01:25:25
missing "
Brendan Burke
01:25:44
End quote on the print
Gary Fitzgerald
01:25:49
python uses True not true
Jack Schefer
01:26:09
bind expects only one argument, that is a tuple of (IP, port)
Sonia
01:26:47
what is 55?
Grady Roberts
01:26:56
number of connections to allow
Matthew Bain
01:26:57
@ Sonia how many connections he can have

01:35:24
Mine isn’t working either
