Router and Infrastructure Hacking (CCC conference last week)
by Gadi Evron 05 Jan '07

05 Jan '07

Hi! Happy new year! At CCC last week Raven Alder gave a talk on the subject (Router and Infrastructure Hacking), which was pretty neat! I figure some of you may enjoy this. I hope the video for her talk becomes available soon. http://events.ccc.de/congress/2006/Fahrplan/attachments/1197-CCC_infrastruc… 2. There was also a lecture on sFlow, by Elisa Jasinska: Video: ftp://ftp.fortunaty.net/video/23c3/wmv/sflow-t4s2.wmv Presentation and paper: http://events.ccc.de/congress/2006/Fahrplan/attachments/1229-sflow.pdf http://events.ccc.de/congress/2006/Fahrplan/attachments/1137-sFlowPaper.pdf 3. Just for kicks, for those of you interested, here is Lawrence Lessig's talk, which is not related to net-ops in any way: ftp://ftp.fortunaty.net/video/23c3/wmv/lawrence-lessig-code-vs-culture-t3s1… 4. I do wish the talk on how CCC set up their multiple-uplink GigE network for the conference was filmed, I call this type of "create an ISP in 24 hours", in a very very hostile and busy environment such as at defcon or CCC "extreme networking". They got their own ASN for 4 days. Set up a hosting farm, surfing, mass wireless, etc. for users, and what-not. Discovered a wireless network vulnerability, a router DoS with NextHop memory issues, etc. Not to mention having to fight off DDoSs non stop, fake APs, thousands of active and abusive users and BGP (I really liked their presentation on RIPE's bgplay - very cool stuff - http://www.ris.ripe.net/bgplay/ ). 3000 end points. 1.6 gigs up, 1.0 gigs down. CCC itself was very good and a lot of fun, there are many other presentations and videos available for download: ftp://ftp.fortunaty.net/video/23c3/wmv/ http://events.ccc.de/congress/2006/Fahrplan/index.en.html Gadi.

NATting a whole country?
by Steven M. Bellovin 04 Jan '07

04 Jan '07

According to http://www.nytimes.com/aponline/technology/AP-TechBit-Wikipedia-Block.html all of Qatar appears on the net as a single IP address. I don't know if it's NAT or a proxy that you need to use to get out to the world, but whatever the exact cause, it had a predictable consequence -- the entire country was barred from editing Wikipedia, due to abuse by (presumably) a few people. --Steve Bellovin, http://www.cs.columbia.edu/~smb
