Disks, data and paranoia

I’m currently going through about 15 IDE/ATA  hard disks and wiping them.  I’m using an old machine to do it.  A friend asked if they could have some of them after they’re wiped, for a friend of theirs.  I guess this post is my way of responding and saying no, sorry.

I have no doubt that the data on them is gone.  But, I intend to wipe them, take them outside and hit them a few times with a 4lb lump hammer, and then take them to the local recycling centre.  So the platters will be clean and the devices themselves will be broken.

This isn’t just my data we’re talking about, it’s the personal data of anyone who communicated with me since I started using computers for electronic communications in around 1992.  I don’t think there’s anything, anywhere on any of those disks that could incriminate me or anyone else, or cause any embarrassment, but hell, why take the risk?  When people talked to me on FidoNet, bulletin boards, by e-mail, usenet, IRC, or any other mechanism that may have kept a record on my machine, I bet they weren’t thinking ‘in 17 years, I wonder who’ll be using the disk this is being stored on’.

So anyway, no sorry, you can’t have my old, crusty, IDE disks, I’m destroying them.

The most amusing thing about the process is that the machine I’m using to wipe the disks (with the case off so I can swap drives in and out easily) is clearly dying, sometimes it boots first time (from Darik’s Boot and Nuke media), but most of the time it gives a random combination of beeps and needs another power cycle.  I think it’s the graphic card slowly dying but it’s hard to tell.  So, if the box lives long enough, I’ll finish wiping these disks and then I get to play with my lump hammer.

Valkyria Chronicles

media_sc_lg_06I recently completed this game on the PS3 and wanted to write a short post about it.  It’s such an unusual game, and yet I enjoyed it a huge amount.  The game is a mixture of anime, first-person shooter, turn-based strategy and roleplaying game, without really being any of those things fully.  The game story unfolds through the use of animated stories about a bunch of central characters who have become involved in a war.  Various chapters open up as the story develops, and each of those chapters has a number of battles.   The stories aren’t interactive, you watch and listen.  But the characters are interesting and the plot engaging.

When you get to a battle, you take control of a squad of troops who you can equip (and you can research new equipment), and train (to improve levels and gain new abilities) and then run through the fight.  The battle itself is a mix of first-person and turn based.  You pick a character to control from a turn-like map, you then control that character directly in first-person mode, running them through the battle dodging bullets.  When you want to engage the enemy you switch to a control system that stops time and lets you aim at a single target, at which point you fire your weapon and then return to real time.  You cycle through your squad, moving them and engaging the enemy over a number of rounds to achieve your objective.  When you do, you’re rewarded with more story and more chapters.

media_sc_lg_09That’s an ugly description of a beautiful game.  The artwork is superb, the characters quirky and amusing and the game play truly engaging.  If you have a PS3 this is a must buy – and it’s been out long enough now that you should be able to pick it up quite cheaply.

Using the ‘net, not being scared by it

People who own the rights to music, film, tv, etc. should, in my humble opinion, learn to love the Internet, and not to be frightened of it.  That’s a nice glib statement from someone who never created anything useful in his life, but as someone who consumes a lot of created content surely I have some experience 😉

I was really struck by this thought when reading Felicia Day’s blog (again), after the release of the Guild song, Do you want to date my avatar.  Within a short time of it being released, there were fan-made movies on YouTube, using that music and animation from games such as Lord of the Rings online, World of Warcraft, Second Life, and others, to perform to the song.

Many content owners would immediately go to war with DMCA’s to have the music stripped from those videos, since it’s clearly not owned by the people who made them but by The Guild, or Felicia Day, or whatever organisation she has in place to own the rights.  Did she start processing take downs?

Nope, she found them on YouTube and listed them as favourites, which let’s them show up on her FriendFeed account.  I can only assume that this eventually increases the sales of the song (because god only knows once you’ve heard it you can’t stop humming the bloody thing) and doesn’t negatively impact it at all.  In the same way that seeing a cool fan video on YouTube with a song by Big Mega Band from the 80’s as the backing track is more likely to make you go and re-buy it on iTunes than it is to make you strip the audio from the vid and import the illegal, low quality version onto your mp3 player.

You either embrace the ‘take it and use it and make something with it’ nature of the ‘net, or you end up fighting it at every step of the way and losing none-the-less.

Felicia Day and creative content owners of her generation are going to make it work, because they accept, use and take part in the medium.

Avatar – the trailer

So, it’s out, Avatar’s trailer, the best place to see it is on the Apple site in HD, here.  Does it look impressive? Yes.  Do the CGI characters move well and have emotion in their eyes? Yes.

Do they still look like CGI? Yes.

Does it look a bit like WoW the movie? Yes.

Bah technology

For some reason, the non-terrestrial channels on our Sky+ box are showing very dark on the TV.  If you switch to BBC1/BBC2/ITV/C4 it looks fine (they’re still being delivered via Sky+ over the same SCART connection).  But anything else you can actually see it ‘flip’ to a darker picture.  On top of that, any dark scenes are causing the black on the TV to get totally saturated and you can hardly see any detail.

I’m positive it only started doing this in the last couple of weeks, maybe even after I switched in the new Sky+ viewing card.

It’s really frustrating me.  I hate when ‘simple’ technology like this doesn’t work and hate it even more that I can’t fix it.

Cygwin terminals!

I use Cygwin both at work and home to give me a quick to access unix-like environment, where I can use tools that I use everyday in my sysadmin role.  I find it a lot easier to wc -l something than load it into OpenOffice and do a word count.  I’m happier with awk and grep and find than Windows GUI tools.

My only real pain was that the terminals under Cygwin were awkward.  The default terminal is terrible (essentially the windows command prompt).  I eventually configured rxvt and got it working pretty much to my liking, but the X-Windows style never really fit well with my other windows and some of the features annoyed me.

However, today I found the MinTTY package within Cygwin and I’m finally very pleased with my Cygwin terminal.  It looks and feels just like a PuTTY window (which it should, being based on the same code) which is handy since I use or used to use PuTTY all the time for remote access to the stuff I support.  It’s configurable (easy) and fast.  Very pleased, give MinTTY a shot if you’re a Cygwin user and didn’t know it was there.

Random ssh attacks

Somewhere on the internet there’s a machine I have access to, which is running an ssh daemon.  That machine has a public internet address.  Between the 26th of April 2009 at 8:55am and the 19th of July 2009 at 1:37pm there have been 105,043 failed ssh login attempts.  That’s over 84 days (roughly).  So that works out at 1250’ish failed login attempts per day.  Which is about 52 per hour which isn’t a million miles away from 1 failed login attempt every minute on that server (it’s actually 0.86 attempts per minute).

The attempts come in batches, so every few hours there’ll be a few hundred from the same source.  Sometimes they try hundreds of passwords against root and othertimes they’ll try hundreds of different user ID’s.

In those 84 days there have been attacks from around 259 different source IP addresses.  As for usernames attacked, there are 17,532 different ones attempted in that period.

The most popular day was the 2nd July with 7387 attacks in one day, from 8 different sources.  Two specific IP addresses accounted for 3173 and 2826 of those attacks.  One source tried 728 user ID’s in 2826 attempts and the other 1615 different user ID’s in 3173 attempts.

The root user ID has been attacked 27,210 time throughout the whole period.  The most popular non-root user ID to be attacked is admin with 2392 attempts, then test with 1330 attempts and in the next slot is guest at 627 attempts.  Application based ID’s were popular with oracle (623), mysql (399), postgres (311), ftp (251) and teamspeak (165).  Amusingly, the most popular regular names attempted were paul (211) then john (201) and michael (180).

There doesn’t seem to be a preferred hour to attack servers, here’s the breakdown by hour,

  • 01 – 5696
  • 02 – 6249
  • 03 – 7387
  • 04 – 4127
  • 05 – 4388
  • 06 – 3457
  • 07 – 4809
  • 08 – 3920
  • 09 – 3481
  • 10 – 4708
  • 11 – 3894
  • 12 – 3062
  • 13 – 3542
  • 14 – 2805
  • 15 – 4481
  • 16 – 5823
  • 17 – 4198
  • 18 – 2160
  • 19 – 2496
  • 20 – 3949
  • 21 – 7980
  • 22 – 4823
  • 23 – 3418
  • 00 – 4187

I could do some analysis of the source addresses, but I’m not really sure how useful it would be, many of them are likely to be compromised workstations or forged address.

False positive …

Firefox is still slow, it wasn’t (just) Adblock plus.  I’ve even tried with a totally clean profile and it can still take 60 seconds to launch.  If Firefox was the last thing I shut down (say last thing at night) then it opens instantly even if it’s 12 hours later (like first thing in the morning).  However, if anything else (reasonably significant) is run in-between then it takes an age.

Investigation continues.

iPhone 3.0 – deleting photo’s

You may remember I had issues deleting images from my iPhone using Windows Explorer when the iPhone was connected via the cable.  Deleting more than one at a time would crash the iPhone.  Looks like the iPhone 3.0 update fixed that and deleting multiple photo’s is super-quick.

A day of updates #4 – Garden Goes Green

I can sense you’ve been longing for an update on the garden.  And you’ve come to the right place.  Right up until the point where I was diagnosed with a hernia I’ve been out in the garden every day it was dry trying to get things sorted.  Once I was diagnosed I tried to cut back a bit, but it’s not an easy habit to get out of.  Grete works in the garden like a demon, weeding, cutting, and keeping everything in good shape.  Who would have thought we’d enjoy a trip to B&Q to buy plants and planters?  Anyway, here’s an update and where we are and how things progressed.

p1060297The New Tree

We’ve bought a new tree for the garden (cherry tree).  When we had to have the huge tree cut down to allow a fence to be put in by our neighbour, we promised ourselves we buy a new tree to replace it, but something we could keep under control.  So we did, and we’ve planted it at the bottom of the garden (at the moment, next to the huge pile of wood I’m no longer allowed to carry and move).

It doesn’t look like much at the moment and we’re really hoping we planted it well enough for it to survive.  It definitely had enough sun and rain in the few days after going in.  We’re trying not to think about the choice of cherry, we already get frustrated by picking up a thousand apples every summer and cherries might just drive us nuts (no pun intended) but hopefully it’ll look nice and the birds will enjoy it.

p1060323Planters

Now that the concrete patio is pretty bare we decided to get some planters to brighten it up and throw a bunch of flowers into them.  We ended up with far too many flowers and far too much compost so we finally sorted out the two mini-borders near the house and used most of the rest of the plants on those.  There are four terracotta planters down the fence side of the patio, each of which we put five or six plants into.  The photo to the left is how it looked when it went in.  Since then the plants have put on a little bit of volume and one or two are threatening to flower.

Along the side and front of the kitchen we dug over the soil and got rid of a rose with a root the size of a small barn, and replaced it with some of the same plants.  That area suffers heavily from snails, slugs and other various vegetable eating life so we’re surprised they’re doing as well as they are.  We did lose one of the plants entirely – one day it was there, the next it was just a stem lying on the ground.  Here’s a few shots of the progress of both the planters and the borders.

Where’s the Grass At

The grass is coming on really well.  The front has really spread and looks like it’ll cover everything, in the back garden it looks a little sparse still under the tree but it’s spreading slowly.  Looks like we’re going to have a mixture of lush green grass and old faded yellow grass, but I guess over time it evens out.  We could try some stuff to fix up the old grass, but honestly we like the garden kind of natural rather than pristine looking golf course grass.

The acer is still alive and looks like it’s doing okay, hasn’t changed in size much yet but they’re very slow growing, hopefully it’s rooted well and isn’t just slowly dying without looking like it.

Woodwork

After putting it off for ages, I finally got around to sanding down and treating the wooden sill at the bottom of the patio door frame.  I think it’s a sill.  Anyway, sanded it down with our little electric hand-sander thing, the stink of cat was pretty bad (see following post #5), took out all the old silicone, treated the wood and put new silicone in.  I hate, hate, hate putting silicone in, I’m so bad at it.  Anyway, photo’s to prove it!

I know you’re probably thinking ‘omg, so you sanded and sealed some wood, so what!’ but this is a big deal for us, so deal with it.
