Site update

I've reorganized my home pages quite a bit. The blog is no longer the default home page and it remains to be seen whether I will even update it as infrequently as I have in the past. I've added all the links needed for the most popular things found here, including links to the software and papers.

NANOG 32 Reson, VA USA

I attended NANOG 32 in Reston. Most of the presentations can downloaded from the NANOG meeting agenda pages. There was one night of tutorials and two days of various presentations and a BoF. As with many meetings of this sort, plenty of useful discourse is done in hallways and at the bar. What follows is a report of the event from my perspective.

NANOG 32 botnets presentation

The following are my Botnets slides from the NANOG 32 meeting. The Botnets audio is also available from University of Oregon.

Software Sig Page

To encourage software maintainers to publish verifiable signatures for released software and to build the web of trust among software maintainers, The Software Sig was created.

ios-ipnames script released

To assist an effort at cleaning up Cisco IOS configurations, I whipped up a small Perl script to check reverse DNS records of interface IPv4 IPs on stored IOS configs. Click the software link at the top of this page to go to the software download page for a copy of this script.

acl-usage script released

To assist an effort at cleaning up Cisco IOS configurations, I whipped up a small Unix-based script to list ACLs that were defined, but not in use on stored IOS configs. On the cisco-nsp mailing list I posted an initial version and within a few hours had enough feedback to include things I had forgotten, plus indication that it, or a derivitate version was put into an upcoming release of ACL_maker from the Cisco-centric Open Source Exchange Community tool (thanks Ed!). The current version here also takes a stab at identifying unused route-maps as well as ACLs. Click the software link at the top of this page to go to the software download page for a copy of this script.

Anycast Addressing on the Internet, Kuro5hin.org article

As part of basic research on Anycast deployments, I wrote and submitted an article entitled Anycast Addressing on the Internet at Kuro5hin. It was originally posted to a community website to try to obtain more diverse feedback than if it was just posted here. To ensure survival of that article, there is also this local copy archived here.

named-report 1.4 released

Version 1.4 of the BIND 9 log summary and report tool has been released today. Click the software link at the top of this page to go to the software download page. This primary reason for this new version is to handle log messages created via syslog rather than just BIND's native logging facility.
