In my opinion, the best SSH client ever is PuTTY Tray. It was originally compiled by Barry Haanstra and can be found here. Recently, the developers of the original PuTTY released version 0.61, which contains an important bugfix for anyone using PuTTY with serial ports. I used to use TeraTerm when fiddling with console cables, but it supports only com-ports 1-4. This is unfortunate because the new USB-serial-adapters like to map themselves to higher com-ports (usually 6) by default. Naturally you can change this, but it's just too much of a hassle. With PuTTY, you can use the higher numbers with ease.

Unfortunately, Barry Haanstra has stopped the development of PuTTY Tray, so there is no version 0.61 at haanstra.eu. This is a pity as that site is unsurprisingly the first hit when you Google "PuTTY Tray". However, Cris West is now maintaining PuTTY Tray at http://puttytray.goeswhere.com/. I don't know if this move is official, but at least it's not mentioned at haanstra.eu. Also, puttytray.goeswhere.com doesn't appear as a direct link within the first 10 Google result pages for "PuTTY Tray" (it's there on the first page, but that's a blog entry). In any case, the version of mr. West appears to be working just fine, so I'll just document the URL here. Hopefully it will appear on the Google results someday.

Gallery back online

The kind folks at Menalto and Gallery-community have finally finished Gallery3, so I have now reconstructed my picture gallery. It can be found from http://gallery.dx.fi/.

Adventures on TUIfly Nordic

I recently had a vacation in Cyprus using the services of Finnmatkat and TUIfly Nordic. The part of the travel agency was handled in a professional manner, as you'll see later, but the same can't be said for the airline. It was not really an epic failure, but a noteworthy episode non the less.

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    91.121.17.80:0     ->  217.30.191.125:0     7.0 M    9.3 G   176

In other words, 91.121.17.80 (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.
