Happy Thursday Everybody
Matthew Bain
15:42
yes
Jake Moses
20:03
Is there any chance you could upload the slides? So we could follow along there too in case we fall a slide behind?
Jake Moses
20:49
Perfect thank you!
Josh Laney
24:28
how does your machine know the ip address of the root dns server?
Sonia
34:43
199.85. 126.20. 199.85 ?
Sonia
35:17
I think it's different for each policy: https://en.wikipedia.org/wiki/Norton_ConnectSafe
Matthew Bain
37:10
When you say malicious, how malicious are we talking?
Matthew Bain
37:55
okay cool
Seth Dolin
41:43
block chain?
Josh Laney
41:46
what/who decides if your request is recursive vs iterated?
Seth Dolin
44:22
If you're doing an iterative query could you only query the first part of the domain so that the root server doesn't get all the information? Like if you want cs.virginia.edu you just ask the root for .edu
Jake Moses
45:12
How do iterative queries cache?
Seth Dolin
50:19
are the identifiers just chosen randomly by the client that's sending the request?
Jake Moses
01:15:28
yes
Seth Dolin
01:15:28
I'm here
Matthew Bain
01:15:28
yeah
Sonia
01:15:34
yes
Jake Moses
01:16:42
Whats u_i?
Jake Moses
01:17:04
Would that be significantly different in terms of server upload time?
Seth Dolin
01:17:10
other than torrents, do you have any examples of things that use a p2p architecture?
Seth Dolin
01:21:32
Is there a way to do p2p without a tracker?
Jake Moses
01:22:00
Could there potentially be a malicious participant in P2P? If one of the connected clients was malicious could they damage other clients?
Seth Dolin
01:24:19
Who decides which chunks get sent from which peers?
Matthew Bain
01:24:32
Do we need to use uTorrent for our project or can we use any client we want
Seth Dolin
01:25:50
per chunk checksums that the tracker sends out to new clients?
Matthew Bain
01:25:51
checksums?
Gary Fitzgerald
01:25:51
hash
Seth Dolin
01:28:26
we could blacklist IPs that leave as soon as they receive all their chunks
Gary Fitzgerald
01:28:29
refuse to send chunks to people with low upload ratios
Seth Dolin
01:31:24
is choosing exactly four peers part of the standard or does the client choose how many peers to have unchoked?
Seth Dolin
01:32:41
OK
