Butterfly flaps have interesting consequences. Apparently Edward Lorenz came up with the term butterfly effect; later he wrote a marvelous paper presented at the 1972 AAAS (speech below, and taken from another site which had the text), which explains the effect… in a way that may or may not align with how you view it. It’s a very easy read of a complex topic, and in it he talks […]
Got an HP server to play with, a Proliant ML 150 G6 (what’s the deal with HP’s wacko URLs?); not too expensive, and is big with really loud fans. When setting up IPMI the man advises you to “use Telnet to log in to the remote management CLP” – I haven’t used telnet in sometime, I had to try. telnet 192.168.0.46 Trying 192.168.0.46… Connected to 192.168.0.46. Escape character is […]
I went to the 2011 USENIX security conference… admittedly not expecting much, but wietse was going to be there, and I must say a really, really fine show. Yes, this is ancient history now… but so am I! Most of us spend a fair bit of time encased in two tons of steel, glass, rubber and more, zipping along at high speeds without a care in the world. In […]

Turns out LWP changed the default behavior that had been around forever – now it dies if a cert isn’t kompletely kosher. Since virtually every Nessus install […]
A one line gawk script to transfer a file to a waiting netcat… it’s sort of a really crappy one-way netcat that you stuff things into. I actually sort of needed this when on a suxx0r really stripped down busybox linux system that had zero file transfer programs, it was a wasteland… but the fools left gawk on the system… so a quick hack to do file transfers: […]
