Carrier Recommendations
by Daniel 17 Jul '07

17 Jul '07

All, I am currently in the process of evaluating carriers for future expansion into international regions, primarily Asia, Europe and South America. I am comfortable with AT&T and Verizon however I would like to make sure I include all the major players and would like your direct feedback and commentary in regards to any of them. These are the key areas I am concerned with. Support Reliability Flexibility Complexity Coverage I am looking at two deployment options as well if anyone would like to comment. 1) A single carrier for global connectivity to all sites (mpls etc) 2) A single carrier for global regional connectivity, and in country/regional carriers for all local offices that funnel back to regional aggregation points. Any insight would be greatly appreciated. Thanks, Daniel

Announcing new KYE paper: Fast-Flux Service Networks
by Lance Spitzner 17 Jul '07

17 Jul '07

The Honeynet Project & Research Alliance are excited to announce the release of a new paper, "KYE: Fast-Flux Service Networks". This whitepaper details a growing technique within the criminal community called fast-flux networks. Fast-flux is an architecture that builds more robust networks for malicious activity while making them more difficult to track and shutdown. In addition to the architecture, the paper covers how service provider networks can detect and mitigate these threats. You can learn more at KYE: Fast-Flux Service Networks http://www.honeynet.org/papers/ff/index.html This is the first KYE paper we are releasing in both .pdf and .html format. Thanks! lance

Cisco 7200 series and G2 NPEs
by Steven Haigh 16 Jul '07

16 Jul '07

Hi all, I'm wondering if there is anyone willing to share any experiences they have had with Cisco 7200 series equipment (specifically relating to the G2 NPE) and any 12.4 based IOS. We were initially advised by Cisco to run 12.4(4)-XD7, however upon introducing our first G2 into the network, the vpdn target routers had a ~20% CPU usage increase, while the G2 itself showed signs of incorrectly establishing tunnels. Changing back to a G1 NPE (same config) and everything works as expected. Cisco has recommended that we move to a 12.2 SB IOS for the G2, however I'm wondering what other people are doing. On another note, it seems as though it is not possible to recover a G2 from a rommon state with invalid bootloader images or corrupt bootflash:. There are no commands in the rommon to allow Xmodem uploads via the console, nor any networking functions. I also noticed that it seems to be impossible to load the bootloader from a CF card - even though you can list the contents of the CF card. Does anyone have any recovery techniques that I'm not aware about in a real world failure scenario? -- Steven Haigh Email: netwiz(a)crc.id.au Web: http://www.crc.id.au Phone: (03) 9017 0597 - 0404 087 474

Actually, you might want to try and duplicate the issue with identical machines sitting next to each other and a piece of cable between them...
