Feasability of unvirtualising guest OS for speed and profit?
by Srdjan Todorovic 11 May '09

11 May '09

Hi everyone, I've got a VMware image of a Linux distro used for development tasks. I use VMPlayer to boot this distro and then I work in it. This distro is virtualised as the guest and host libc/toolchain/etc are of different versions (and also incompatible). But it's a pain to keep all the windows confined to the VMPlayer window. So, I was thinking of: - copying out the files from the vmplayer distro image to a specific directory on the host filesystem - chrooting to this directory - maybe setting up LD_LIBRARY_PATH or something similar (though if I'm chrooting, I doubt this step will be needed) so as to: - take advantage of SMP when running make - split out windows from 'pseudo-guest' distro across two screens - not have to faff about with vmplayer and the slight performance penalty - not have to worry about removable devices and vmware's handling of them. At some point, I will try this out. But has anyone ever tried this, and did you run into any particular problems? Anything nasty/tricky to be careful of? I don't specifically need the guest OSs kernel to be booting, which is why this is possibly a nice plan. Thank you Srdjan

Netbook question(s)
by Chris G 07 May '09

07 May '09

I'm thinking of getting a cheap netbook to take on a (motorbike) holiday next month. It'll be Linux based of course and my requirements are pretty simple. All the basic, cheap netbooks will fulfil my basic requirements I think - i.e. they have a browser, can connect to the internet by WiFi, etc. However I have a couple of specific things which aren't always addresses in the advertising blurb:- How easy is it to add software? I really have to have ssh as that is how I access my E-Mail and that's one of the major reasons for getting the netbook. Are the "as supplied" Linux distributions sort of cast in stone or can one add things? I don't want to have to do a complete installation of a new distribution just to get ssh. Do any of the netbooks have a trackball rather than a pad? I really don't know why trackballs aren't more popular, I use one on my desktop and we now have a wireless keyboard with a trackball and it's magic, no separate mouse to lose/drop and the trackball is much nicer than a pad. -- Chris Green

"Hacked to Pieces"
by Ted.Harding＠manchester.ac.uk 06 May '09

06 May '09

Hi again, folks. This is a sort fo follow-up to the Syleham gathering, since as I started to drive home after the meeting a programme "Hacked to Pieces" had just started on Radio 4. It is about computer crime, and how vulnerable most people are because of naivety about security. The programme can be found at 17:00 on http://www.bbc.co.uk/radio4/programmes/schedules/fm for today Sunday 3 May (in case you're reading this later). If you click on the link "N days left to listen" you can hear it. The bit that raised my eyebrows starts at 5min 30sec into the programme, where the presenter (Jolyon Jenkins) takes his laptop to be hacked into by Peter Wood of First Base Technologies (who provide a "hack your computer, guv?" service to companies who want to check their security). It lasts to 7min 40sec into the programme. In particular, I transcribed the following short extract: JJ: I was genuinely suprised by, in fact, how vulnerable I turned out to be. PW: The first thing I'll do is an easy check to see whether I can get a nice little automated tool to cough up your password straight away so I can log on as you. JJ: I'm fairly confident you're not going the get my password, because it's not a natural language word. PW: This isn't dependent on any dictionary-based word, it's just trying every permutation of letters and numbers up to 14 characters long. JJ: Ah, I'm feeling less confident because ... PW: Ah! There's your password JJ: Oh! PW: That took two hundred and ninety seconds of computational time. Well, my jaw would drop if I believed it! Even if the password is case-insensitive, that's 36 letters+numbers to try every "permutation" of. There are 36^14 different 14-character strings where each character can independently be any letter or number. And that's just the full 14-character string -- there's also all the shorter strings as well. Now, 36^14 is about 10^22, or 10^13 billion, or 10,000 billion billion. A 1-GHz CPU would take 10,000 billion seconds to execute that number of CPU cycles, or about 300,000 years. So there's no way the guy's password hacker is going to do what he said it would do. It's not too plausible when it comes to searching for shorter passwords either. An 8-character password (case-insensitive) still potentially requires 36^8 or about 3*10^12 tries; so (based on the previous calculation) that's 3,000 seconds or 0.83hr to execute 3*10^12 CPU cycles. Then you have to multiply that by the number of CPU cycles needed to work through each try, which is presumably not a small number. And it's worse if passwords are case-insensitive, since then there are 46^8 approx = 2*10^13, or 20,000 billion tries for an 8-character password, and it's 5.6 hours to execute that number of CPU cycles on a 1 GHz CPU. So the "outcome" of that little experiment strikes me a implausible, and I susepct that it was "rigged" in order to sex up the story. (Maybe JJ used a shortish password -- 46^6 is only 9.5 billion). This sort of thing is supposed to take place in the context of people (e.g. attending meetings/conferences) leaving their laptops unattended for say half an hour, thus allowing the hacker physical access. (And, by the way, it seems they're thinking of Windows machines). I'd be interested to hear if any of you folks have comments on the above!

The signal for my network is flaky inside the hall but I will pop outside from time to time at the beginning to check for voice mail or text and will call you back. 07908 222428 Looking forward to seeing old friends and some new faces.

Mountain Rescue
by Ted.Harding＠manchester.ac.uk 04 May '09

04 May '09

The majority of us fenny amphibians don't normally have to worry about such things, but people who venture out on the Cambridgeshire Alps do have to worry. These are a chain of mountains running North from Huntingdon/St Ives out to Warboys and thereabouts. The Pidley Mountain Rescue Team seems to have changed its website: http://www.pidleymountainrescue.org.uk/ I can no longer view what they've been up to, since I'm now told that "additionaql plugins are required to display all the media on this page". When I click to install the missing plugins, it announces "Java Runtime Environment", but when I try to comtinue it says "No plugins were installed. Java Runtime Environment Not Available." Then taking the option for "Manual Install" I get shown a choice of RPM (jre-6u13-linux-i586-rpm.bin) or self-extracting binary file (jre-6u13-linux-i586.bin). I'm running Debian Etch with Iceweasel browswer. I've looked into what synaptic comes up with when I search on "java" or "runtime" or "java runtime". Up comes a lot of stuff, of which one is Java runtime environment using GIJ java-gcj-compat is a collection of wrapper scripts, symlinks and jar files. It is meant to provide a Java-RTE-like interface to the GIJ/GCJ tool set. (and it says version 1.0.65-10, whereas the java runtime offered by the "Manual install" is "version 6, update 13"). I'm hesitating, because I don't want to do the wrong thing here, nor mess things up by installing incomplete or incompatible things. I'd be grateful for advice about installing java runtime in a proper way in my setup. Maybe I'm suffering the effects of altitude sickness, after the trek over the passes between here & Syleham yesterday!

Syleham photos
by Ted.Harding＠manchester.ac.uk 03 May '09

03 May '09

Greetings all! A very agreeable gathering at Syleham today, and it was good to meet up with people again. Thanks to BJ for making the arrangements, and for assiduous bar duties. (There's a sign on one of the doors which says "Push Bar to Open" and I thought of trying that, but BJ got there first). I took a couple of photos at the end. Not everyone is well portrayed (unless a couple of folks are keen on the backs of their heads), maybe not everyone still present was included (and certainly a nice pair of tiny persons got omitted), but I think they capture the atmosphere. They can be viewed at http://www.zen89632.zen.co.uk/ALUG/ This is just a directory, and contains sylehamALUG_2009.05.03A.jpg sylehamALUG_2009.05.03B.jpg which can be viewed directly by the usual right-click procedure, or downloaded (1.8MB each). Till next time! Ted. PS (taking up on a topic of conversation at the time) in case anyone hasn't come across it yet: Help-Desk sagas go back much longer than most people think.
