been seeing some strange latencies appear in my dns lookups for the past day. haven't yet figured out why .... for more information on global dns performance, check out the guys at caida.

was working on fw-mon in the second half of this week. it's coming along nicely, and if i ever get back into firewall consulting it would probably be a product i would add to the whole thing. as it stands i'm not going to release any more updates, like i said, not until i have left arbor (which i dont plan on doing for a while). needless to say it's some neat stuff and i'm pretty proud of it so far (but it's got some way to go).

the book's coming along nicely. broke 60,000 words last night and just broke 200 pages (with only 10 figures or so, and i have 20 more to add). i'm about half of the way done with the detection section (section 3 of four, made up of 3 chapters). lots more to do there.

wormnet is up and running, i need to finish it up. only a prototype is set up. if i wanted to do this right i would probably sink several grand into it and include topological interests, as well, like inter SP links. if i like how this whole thing turns out i'll write up a paper on it specifically for something.

shown above is an analysis of the output of the random number generators in SQLsnake and Slapper, two worms i'm currently analyzing for my worms book. the network generation portions were taken from the worms and the first 100,000 data points were analyzed. the frequency of the first two octets (ie 192.168.x.y) are plotted in red for slapper and green for sqlsnake. obviously, sqlsnake is not nearly as evenly distributed as slapper. the gaps in slapper's ditribution as you go from left to right are because it skips unallocated networks.

woe be to the people in the networks 216/8 and 64/8 for sqlsnake. they got pounded.

new snapshot of the unofficial ports tree up for openbsd. a few additions, including jolan's silc-server port, bmf from han, and a few updates. have a peek, give feedback to the authors about the ports. i'm using many of them myself.

you have to hear this: a cover of rocketman by an ad hoc band. basically they found some musicians from the classified ads and put them in a studio to play. this is what they recorded ... strangely beautiful.

in other news, stratfor and morning edition had different takes on the situation with chavez in venezuela.

if you thought google news was something, newsseer will knock your socks off.

had a productive night mining for data on citeseer. lots to read in the next few days.

if you're an openbsd journal reader and you're wondering why some of the stories have been kind of lame lately, it's because i'm writing two books and working on some deadlines. just turned in a milestone on one of them and so i should be able to get back to the duties i assumed and turn out good stories again. also, feel free to submit some stories about openbsd or related material.

i'm looking forward to a weekend without worms. i plan to read chris' thesis and write up a book review for deadly (and maybe one for slashdot, too). got the oreilly ipv6 book yesterday for review on deadly. it's not bad, but i'll have a more complete review up there. it does have the most complete ipsec description i have seen in a long time.

working with a wiki using awki, an awk only wiki implementation. it's pretty cool ... using it at work.

announcing the unofficial openbsd ports tree. basically, getting updates to people has been tough, so some of the people who are actively porting stuff are working on the unofficial ports tree. this will allow us to help people get new ports for testing. examples include some of the tcl ports i have done lately and the gnome2 stuff from jim and marc. you can find a snapshot of the tree here: unports-10062002.tar.gz. download and unpack and use the regular ports tree methods.

cranking up some qbert and assorted djs as i work on my book. almost done with the last chapter in section 2, and then the fun begins in sections 3 and 4.

well, i did it. i'm now officially made up for where i was last sunday in terms of distance moved. and i'm about 8,000 words richer, too, meaning i'm that much closer to my goal of 50,000 words for this milestone. the current chapter is a lot less painful than the other ones i've been working on.

a recipe for some people. i'm glad folks like them, and i'm happy to share the food. a month or two ago i shared a recipe for sweet potato pie, here's another one provided by a friend which i think i will have to try. in the meantime, here are two recipes for you. the first is from eating well, a magazine which folded some years ago but still is the source for many of my recipes. the other one is one i made up this evening and enjoyed.

raspberry coffee cake

2 cups all purpose flour
1/2 cup sugar
4 tsp baking powder
1/2 tsp salt
1 large egg
1/2 cup skim milk
1/2 cup plain yogurt
3 tbsp canola oil
1 1/2 cups raspberries (or blueberries or blackberries)

3 tbsp sugar
2 tbsp freshly chopped walnuts
1/4 tsp cinnemon

mix the dry ingredients, mix the wet ones. add the wet ingredients to the dry and mix until just mixed together. don't overmix or the batter will get stiff, and it will form a dry crumbly mixture. add the raspberries and gently fold them in. mix the nuts, sugar, and cinnemon for the topping and top the batter with it. bake at 400 degrees F in a baking pan for 20 to 25 minutes. serve warm.

thyme chicken

2 boneless, skinless chicken breasts, butterflied
1 cup flour
1 tbsp salt
2 tbsp olive oil
2 tbsp butter
1/4 vinegar
2 time 1/4 cup water
1 tbsp sugar
2 tbsp fresh chopped thyme leaves

dredge the chicken breasts in the salt and flour, cook on medium heat in the olive oil until golden brown. add the vinegar, sugar, and 1/4 cup water. raise the heat to medium high and evaporate off the vinegar. reduce, add 1/4 cup more water with the butter and thym and reduce again to get a thick, sheen sauce. serve immediately with vegetables and potatos.
