Comment: Don't bother trying Btrfs. (Score 1) 42

by d33tah (#48327465) Attached to: OpenSUSE 13.2 Released

I am using OpenSUSE 13.1 right now with ext4 partitions and I am pondering migrating to OpenSUSE 13.2 with btrfs or simply updating the distro with ''zypper dup'' and keeping my ext4 fs.

If you are using btrfs, what has been your experience? Better performance? As stable as ext4?

You can't really say how much disk space you have (especially if you use compression and snapshots), overfilling the hard drive might leave you in a situation when you can't basically do anything other than reformatting the filesystem, and from my personal experience support for directories with loads of files is much worse than in ext4. My advice - don't bother.

"We are working on a vast and ground-breaking census, this time we hope to do it legally. Please help us make this happen by donating bitcoins to: 1tUCEnTyKzWrTBn1tgruSRkfahGUhxHcq"

Internet Census 2012 was a biggest complete scan of the entire internet with results being publicly available. This included traceroute information, port scanning, service and OS fingerprinting and more."

"Apparently the researchers didn't analyze OS fingerprints at all."

Did you look into their paper? This is apparently not true. They focused on the ICMP data set but also looked into others, in particular the service probes that you mentioned. One of their validation sets is using that data set.

Okay, point taken about the service fingerprints, but I still see no mention for the OS fingerprints. If they looked at the data format that is there, they could get much more out of the set. (they'd also find more mess by the way as there was some weird bug that destroyed quite a few samples there)

Apparently the researchers didn't analyze OS fingerprints at all. There is some metadata that the original researcher(s) forgot to remove (as well as a lot more mess). Service fingerprints are interesting as well. I did a lot of research on this data set and I have to say that while messy, this is also a really amazing data set. This article is IMHO biased.

Hashing is just not going to help there. The DNS domain space is basically so little that it could probably even be bruteforced offline, not to mention web crawlers. You can easily download the rDNS for the whole internet as of 2012 from Internet Census 2012 database for free (http://internetcensus2012.bitbucket.org/paper.html). While it's not forward DNS, I would expect to get a very high match rate just by hashing it all. Definitely feasible.
