I currently smell bad, mud is stuck to every major part of my body, and I feel very content. I’m also amazed at just how much water the skin on my head can wick from the rest of my body, only to sweat it out. (Yes, I have a big head and it is really oily and sweats a whole lot.)
Tonight my brother-in-law Craig and I met up at the Stony Creek mountain bike trails, as he’d just acquired a new-to-him bike and we wanted to do some riding. Not far into the trail we happened to run into the folks who were doing the regular Wednesday Night MMBA ride and tagged along with them. As we’d hit up The Pines earlier, we ended up covering all of the single track in the park, pretty much none of which Craig had been on before.
The ride was pretty uneventful and fun, and Craig seemed to do quite well for his first time on them with that bike. I almost fell once on The Pines when learning just how slippery mud is, but that wasn’t a huge deal. The mud after that just meant that both my bike and I regularly got sprayed with lumps.
After finishing up about 9.5 miles in the mountain bike trails Craig headed home and I took off to ride over to the still-under-construction Skills Park so that I could see it and hoping to meet up with Nick / Dirt. I’d been told that there were people there working on it this evening, but everyone had already left so I took a few minutes to down half a Clif bar (I was feeling a bit faint) and then headed back to the car and home.
Total distance today was about 14.5 miles, with more than 2/3 of that being off road, and primarily single track. I feel good.

You all know those shiny download tools which open loads of connections on a file to try and get it quicker? Those are crappy and put lots of unneeded load on servers. Here’s an example:
I host this simple page for a friend of mine in the UK for when he needs US-based hosting or some place high speed to distribute files from. As part of this he hosts the animations found on this page, which overall aren’t very big. However, someone in Thailand (125.24.191.195) is deciding to get them as quickly as possible using some stupid download tool.
What I see is that the workload on the httpd is at ~277, up from it’s typical of 2 or 3. netstat shows lots and lots and lots of connections (currently 276) from that box, all of them established.
The http log currently shows 9291 these:
125.24.191.195 rowla.dyndns.org - [11/Jun/2008:16:58:34 -0400] “GET /justin/img/piston_std4.mpg HTTP/1.1″ 200 32768 “http://www.wis.co.uk/justin/deltic-engine.html” “Mozilla/4.0 (compatible; MSIE 5.00; Windows 98)”
Load on the box itself is .23, which is tolerable, so I’ll probably let this continue. If it’s still going at midnight I’ll take some action, but for now it’s just a bit of irritation. Yes, I know I could limit connections on a per-IP basis, but I prefer not to do this unless it’s actually a problem. If I do need to block that IP, I’ll probably just fail to return anything on that vhost to that netblock. Hopefully they’ll finish getting their file sooner than that.
If you’d like to see it, here’s the current netstat: netstat_11jun2008_1.txt
Here’s a capture of a minute or so of 45 seconds of traffic with that address. Note that each GET results in a whole conversation of only 10k or so: 11jun2008_weird_1.cap.gz
