ARM emulation
by Mark Rogers 18 Apr '12

18 Apr '12

I want to play with Linux (inc. maybe Android) on ARM platforms, and figured the Raspberry Pi would be a good target platform, albeit hard to get my hands on right now. Has anyone here played with this who can give me any suggestions as to where I should start? I can see various suggestions on the R.Pi website (QEMU or Scratchbox) so I'm really just asking to seek the benefit of anyones experience here, otherwise I'll pick one of the examples out there and see where it gets me. Separately: I've not done a lot with ARM in the past. How transferable are skills learned (and code written) between ARM platforms? I quite like the look of some of the ARM dev boards you can get on eBay, for example, and I'm sure the range of options will only increase over time, so I don't want to tie myself to the R.Pi any more than I need to at this stage. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Job Vacancy: I'm moving jobs, and am looking for someone to fill my shoes
by Jim Rippon 18 Apr '12

Hi all, Let me start by saying I am not a recruiter, this is a genuine attempt to help my employers find a replacement for when I leave for pastures new in June. They are looking for a Network Admin / Linux Systems Admin based in Cambridge. Its working as part of a small local team, responsible for production and office systems in the UK and EMEA and as part of the larger organisation based in two locations in Canada. I can certainly recommend the job, the team are good and there's plenty of interesting work coming down the pipeline to get your teeth into, as well as the possibility of travel to other locations in the organisation as appropriate (for example, I have travelled to FOSDEM in Brussels this year with the company as well as trips to our datacentre and corporate offices). Systems I work on include: * Cisco switching, routing, security, vpn, mpls, vlan, qos * Juniper firewalls (SSG-series), ssl vpn (SA-series) * Sonicwall firewalls * Checkpoint firewalls * Linux (mostly RHEL/CentOS, also some ubuntu/debian) * HP Proliant Servers and storage * HP MSA SAN * NetApp iSCSI SAN * IoMega iSCSI NAS Software I use lots of: * RHEL 5/6, CentOS 5/6 * Puppet * Nagios * Cacti * Rancid * RT Request Tracker * Splunk * MySQL Useful skills: * Network design and security focus * Perl/Bash scripting They are looking for a network and security focus, so any Cisco, juniper, security certifications or experience would be a bonus, as well as any certifications and experience in Linux specifically RedHat. I'm not party to the budget for the position, but would expect it to be fairly competitive and there is the opportunity to join the on-call rota for additional pocket-money (roughly once every 4-5 weeks having 24/7 break-fix on-call responsibility for production systems, not usually too disruptive). If you are interested, or know someone who might be, please get in touch by email and I'll let you have more details and answer any questions that I can. Regards, Jim

"stumbleupon.com"

Greetings All! I wanted to follow up on the Health and Social Care Bill 2012, and was led to the link: http://www.dh.gov.uk/health/2012/03/royalassent/ When I go to this using Mozilla Iceweasel, I get a brief glimpse of the relevant page, which opens: Health and Social Care Bill gets Royal Assent 27 March 2012 Then the screen goes blank, and the browser hangs forever (i.e. still hung after 20 minutes) with "Read platform.stumbleupon.com" showing at the bottom. This is with Iceweasel 2.0.0.19 on Debian Etch and Iceweasel 3.0.6 on the later Debian Lenny. However, when I tried the same link on Windows Internet Explorer there was no problem. The full page came up, and there was no mention of "stumbleupon". This is on Windows Vista (some years old). I've not had this problem with other sites, including Government websites such as http://www.legislation.gov.uk/ukpga/2012/7/contents/enacted (another link in the Health and Social Care Bill search), so I'm wondering how it came about and what to do about it! Anyone else experiencing similar problems? An6y useful knowledge? With thanks, Ted. ------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)wlandres.net> Date: 17-Apr-2012 Time: 11:08:07 This message was sent by XFMail -------------------------------------------------

I do have one on order (ie I got to the point of them taking my CC details, so I got past the waiting list to get that far) but no idea when I'll see the device for real. In any case I'd like to have an emulator to play with because that's more portable (ie I can play anywhere I have my laptop without taking hardware with me). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Pointing Device Problems
by Paul Grenyer 12 Apr '12

12 Apr '12

Hi All I've bought a LP107T from August International Ltd pointing device and I'm running Linux Mint. When I plug the device in, the buttons that should move my Libre Office slides actually just move the mouse from left to right. Is there a Linux configuration setting I can adjust to fix this? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer

The meeting officially starts at 8pm, although some people may arrive earlier. More information on those people can be found on the list and the IRC channel. If you are unsure if you will recognise us then make yourself and your intent to attend known by either posting on list or visiting us on IRC so we can look out for you rather than hiding in the corner.

Another possibility is look for heaps of electronics on a table that may possibly look like movie props that would used for detonating explosives. Feel free to bring electronics/laptops/gadgets to the meet, you will by no means be alone. Ben Bewick aka Viperfang NB: This mail is automated, please refer to the usual sources for more information.

Re: [ALUG] Machine won't boot after re-install

But I need some more :-( All of the icons on the desktop (I'm the only user) have a red exclamation mark against them and won't run. I've looked at the properties of the icons and they show 'User: 500' and 'Group: chris'. If I look at the /etc/group file, part of it shows this :- chris:x:500: vboxusers:x:502:chris boinc:x:419:chris gnokii:x:418:chris nas:x:501:chris I've looked at various sites online trying to get to grips with groups and users but to no avail. What should I change/add/delete in this file to fix the problem? I think somebody did try to explain this to me in the past but although I kept the mail, I can't get Thunderbird to run so I can't find the relevant mail. The various files in /home/chris show up as 'chris chris' when listed with ls -la I have to confess that it may be caused by a typo on my part! I'm not sure if my account should be Chris or chris so is that likely to be the problem or a red herring?

Does something happen to a WLAN connection every minute?
by Mark Rogers 05 Apr '12

05 Apr '12

I've spent pretty much a whole day on this.... I have a little (ARM-based) Linux (Ubuntu) box connected wirelessly to my LAN. Every minute (via cron) it runs a script which opens a UDP port, then sends a UDP message every second (for 59s) logging the result. For hours I could not work out why more often than not, the script would lock up to 45s then hang - subsequent runs would fail because the port was still held open, and I had to kill the previous instance of the script to get things working again. If I put delays in the script so it didn't do anything for the first (say) 40s, then it still failed at 45s. If I removed the delays so it ran all 60 requests without gaps, they all completed fine (in a couple of seconds). Then on a whim I rebooted and nothing changed, except that the 45s became 38s. Then on another whim, I plugged in a network cable and it's been stable since. So, what might be happening every minute that would cause an existing UDP "connection"[1] to fail? Looking at syslog, the 38s ties in with when NetworkMangler brought the wireless connection up (with dhcp). If it's likely to be hardware specific then I'll probably just change the hardware, but I'd like this to work wirelessly and if there's something happening behind the scenes that could cause this I'd like some clues as to what it might be! [1] Yes, UDP is connectionless so this phrase is a bit meaningless. Hopefully you know what I mean. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
