Q: Is the test open book,
or can we bring crib sheets ? 
A: The test is closed
book, no crib sheets allowed.
Q: Do you plan to put
the RFC and class notes about LPD on the homepage? A: There is no RFC for
lpd. The lecture was taken from the book and there were no prepared lecture
notes (you need to read the book).
Q: You want us to read
all 70 pages of the FTP RFC? A: You don't need to
memorize the complete RFC, but you should probably read most of it.
You should have a good understanding of FTP including the connection models, request and reply formats and file transfer modes. You don't have to be able to reconstruct state diagrams of the restart or login commands, but on the other hand, you shouldn't be ignorant of their existence.
Q: In what case would
I want to use a FIFO but not a pipe? A: HINT: How would the
requirement of using a pipe instead of a FIFO have affected your solution
for project #1?
Q: I'm not certain about
what is meant by transfer mode, in FTP. I thought that would be ASCII versus
binary, but in the RFC, it looks like the modes are stream, compressed,
and block. Which way should I be thinking for the test, and how detailed
do we need to know these modes? A: The transfer modes
are :
- STREAM
- BLOCK
- COMPRESSED
You should understand the differences and be capable of venturing a guess as to why all three modes are supported by FTP.
Q: How much extra is
the extra credit worth? A: Not enough to worry
about.
