Gallery broken

I have just failed miserably at upgrading the gallery to the latest (2.3.1) version of Gallery. I didn't bother with debugging very much, but I guess the PHP 5.3 upgrade broke something, which resulted in an un-upgradeable installation of Gallery. I did try reinstalling it with the old data, but that just broke it completely. The new Gallery 3 is approaching it's release, so an overhaul of the three-year-old installation would likely have been expected anyway. Until then, the gallery remains offline.


My first DoS attack

My first DoS attack

Interestingly, someone has just tried to DoS (perform a Denial of Service -attack) this server. As far as I know, this was the first time my Internet presence has come under a real attack. Everything before this has been normal backgroung noise.

The attack itself was pretty lame. Just a single host (so this wasn't a distributed DoS) in France pushing out 100mbit/s worth of tiny UDP-packets and it lasted for less than 20 minutes. You can see the packet rate from the attached graph.

Here's what our netflow-analyzer had to say about the attack:

Date                 Proto   Src IP Addr:Port         Dst IP Addr:Port Packets   Bytes Flows
2009-10-07 11:16:11  UDP     ->     7.0 M    9.3 G   176

In other words, (ns38798.ovh.net) sent me 7 million UDP packets.

And what about the effects of the attack? The websites were a bit sluggish, as the link was saturated, but other than that I didn't notice anything else worth mentioning.

I had my "old" HTC Touch HD out for sale at a Finnish auction site called huuto.net recently. It's now sold and shipped to the new owner, but I did receive a couple of interesting offers on it. These guys have apparently been roaming around on other online auction sites as well, so this is by no means a unique story, but I thought I'd share it publicly anyway.

The story begins on July 26th when I put the phone on aution...

HTC Touch Pro 2

I've been using my new smartphone, the HTC Touch Pro 2, for a week now and I'd like to present some thoughts and obervations about it. This post is not intended to be a full-blown review and therefore some knowledge on the Windows Mobile 6 platform is assumed from the readers. It also helps if you are familiar with the latest TouchFLOâ„¢ 3D interface. If you haven't actually used the Touch Pro 2 yourself, I suggest watching some video reviews from Youtube before reading this post.

Spam flood

Yesterday (April 23rd), just after 18:00 Finnish time, I noticed a few reports on IRC channels regarding a large increase in the amout of spam. I then checked the statistics of our customer spamfilter (I work for an ISP, remember?), and sure enough, a flood of spam was coming in. In a matter of minutes, the amout of spam had increased by a factor of 4 with spikes going twice as high. To give you an idea of the figures, the number of emails blocked on average was about 2,5 times as much as it was just before McColo was blocked from the internet. Five hours later the flood came to a sudden halt. It stopped just as abruptly as it begun.

We didn't look that closely on what was the content of these messages, but apparently most of them were faked Western Union recruitment emails. They were aimed at Europe, so that might explain why SpamCop didn't see any increase in spam volume. I haven't found as detailed realtime statistics on other sources, so I can't really say how widespread this incident was outside Finland. Also, I haven't seen any reports of it on the NANOG mailinglist, so quite likely it's been a usual day on the other side of the Atlantic.

The day before yesterday, Marshal8e6 released a report on their botnet analysis, including some numbers on spambot capabilities. So just a day after a botnet research lab reports on their spambot findings, we see a sudden shitstorm hitting our filters. Coincidence? I don't think so.
