Apache SSL
by Mark Rogers 24 Jun '10

24 Jun '10

I have a site with a cheapie SSL certificate from 123-Reg. It has been working for the past couple of years but they've just sent me a new certificate which is crashing Apache when I try to install it. The Apache config for the virtual host includes: SSLEngine on SSLCertificateFile /blah/blah/mysite.123.cert SSLCertificateKeyFile /blah/blah/mysite.123.key SSLCaCertificateFile /blah/blah/AlphaSSLroot.crt This differs from the instructions on 123-Reg's site: http://www.123-support.co.uk/support/answers/installing-your-ssl-apache-ope… .. but is working. I don't know the reasons behind or the implications of the differences. When I drop in the replacement mysite.123.cert, I get the following error_log: [error] Unable to configure RSA server private key [error] SSL Library Error: 185073780 error:0B080074:x509 certificate routines:X509_check_private_key:key values mismatch Frustratingly, "apache2 -t" does not report any config errors but this problem crashes the server. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Embedded Linux boxen for VPN access
by Mark Rogers 24 Jun '10

24 Jun '10

Suppose I have a network device (not a PC, but it talks TCP/IP - eg a printer, although in this case it'll be some industrial hardware), and I want to install it on a customer's site in such a way that I want to be able to securely access it remotely with minimal changes at the customer's site. One option is to have a little black box which makes an outbound connection through the site's Internet connection to connect to a VPN, and in doing so providing access to the network device. Any suggestions for that little black box, and for how to configure it? I am assuming of-course that the little black box will be Linux based. I have seen some industrial solutions which (I think) allow both the client (some block in an office at his PC) and the device to set up a small peer-to-peer secure network using a third party mediation server to allow the connections to establish (similar to the ways that stuff like Skype, Hamachi, etc work). However they're very expensive (typically £500+ at each end) and I'd rather have something I have more control over anyway. (If that means running my own mediation server that's not necessarily a problem.) However, there may be simpler options: the black box connects to the office's PPTP VPN, and creates a local NAT'ed subnet with port forwarding through the NAT router to allow device access, etc. (If it sounds like I'm waffling it's because I don't really know what I'm talking about :-) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Arduino Help
by James Bensley 21 Jun '10

21 Jun '10

Is my Arduino duffed or me? Started a new project today, hooked up a 16x2 LCD, and a potentiometer. To start with the screen is simply displaying the reading from the pot with analogRead("PotPinNumber") but its fluctuating like mad: Here is a video on YouTube (http://www.youtube.com/watch?v=fgEm7czlUVg YT has cut eh quality so it isn't very clear!), to start with I have turned the pot to max and you can see the fluctuation in the reading, then I unplug the pot from the analog input so it should be reading nothing but it drops to about 450 and fluctuates around there when surely it should drop to 0 (mystery voltage from somewhere perhaps?), then I plug the pot back in the analog input and you can see it go back up and fluctuate. This is the case irrelevant of which port the pot is plugged into and weather it is plugged in or not it still reads something? Is the Arduino dead or am I dead? -- Regards, James. http://www.jamesbensley.co.cc/ - There are only 10 kinds of people in the world, those who understand trinary, those who don't understand trinary and those who don't understand trinary.

Locating duplicate images (fslint?)
by Mark Rogers 21 Jun '10

21 Jun '10

I have an "images" directory with several subdirectories (and sub-sub-directories), one of them called "products". Pretty much every image in the "products" directory is a duplicate of an image in the parent "images" directory or one of its other subdirectories, although with a different filename (binary contents will be the same, and there's a good chance that the timestamp will also be the same although this is not guaranteed). I want to locate the duplicates, and remove them - the ones I must keep are the ones in the "products" subdirectory. Ideally I'd like to move the duplicates into a temporary directory (retaining their sub-directory paths) rather than delete them in case I need to restore them, but deletion wouldn't be too bad (I can take backups first, although it's on a hosted server and the "images" directory is 1.1G, with free space on the server a little less than that, so just duplicating the directory won't be as easy as it might sound - the lack of free space is one of the main reasons I need to do this!). Oh, and there are some sub-directories I'd like to exclude. So: Which tools should I look at? fslint springs to mind but I've never really used it in anger and the documentation seems a bit vague. The GUI option is out because there's no X on the server. Are there other, better (more appropriate) tools? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

Hullo, Does anyone use GIT? I want to know if one can use git-archive to retrieve a tarball snapshot of head revision at or before an instructed date. Google is not being my friend. Thanks, Jenny

HOWTO: Getting started with OpenVPN
by Martin A. Brooks 20 Jun '10

20 Jun '10

I wanted an OpenVPN server, but didn't want to mess around with client certificates. It took me more googling than I liked to figure it out, so I wrote the procedure down: http://hinterlands.org/wiki/index.php/OpenVPNQuickstart

DropBox Wont Install
by Simon Royal 18 Jun '10

18 Jun '10

Hi I use DropBox to backup my pictures. I have used it for years and think it is brilliant. I sync my pictures folder across different machines including my iBook G3 and my XP partition on my ThinkPad. I had it also installed under Xubuntu on my ThinkPad, however I cannot get it to work under Ubuntu. I installed the package from the Ubuntu Softwre Centre, that went fine. The first you run it it has to download the daemon and that is where it goes wrong. It is very slow downloading it and then it sits at 91% and doesnt move. Any ideas? I tried Googling the problem but I couldn't find any answers.

Ubuntu Start Up Sound All Of A Sudden
by Simon Royal 18 Jun '10

18 Jun '10

Hi As you probably know I have finally gotten sound working on my ThinkPad. I got audio CDs working, MP3s working and web sounds like YouTube. I have had it working for about a week and it has been fine. However, this morning I turned on my machine, booted it, installed the updates Update Manager told me to and rebooted. On reboot, I heard for the first time ever on this machine the Ubuntu start up chime. I've not changed any of the settings apart from installing the updates, and my sound voulme has always been up full.Just curious to why it has suddenly started.
