[Hampshire] HantsLUG / Southampton Makerspace
Hello, I realise from the website HantsLUG hasn't met for a fair while - and we've offered before when we were much smaller - but I just wanted to let you know that now So Make It have moved into a larger space (~1200 sqft) you're still welcome to meet there (no cost, though donations are welcome!). The new space is really quite large compared to our older space, hopefully some photos from our grand opening yesterday give a good impression of the size: https://www.facebook.com/media/set/?set=a.588087417988342.1073741853.269112773219143type=3 (You don't need a Facebook account to view this link.) I'm afraid I'm overwhelmed with email these days so I'm not following the mailing list like I used to - please feel free to contact me off-list if I seem to have missed a response!

You could make a very small plugin so only email addresses on the mailing list can be used to register new members; this could be combined with other defences.

[Hampshire] Tmux - the terminal multiplexer
Does anyone here use tmux (as opposed to screen) for terminal multiplexing? I've been using it for a few months and it's awesome - especially v1.8 which was released just a couple of weeks back. I no longer use tabs/multiple terminals - everything on my system goes through one single terminal window via tmux sessions, windows and panes; even when I'm working locally only. I'm aware that screen can do some things that tmux can't - I'd love to hear from anyone who uses these screen features so I can learn what I'm missing out on! If anyone would be interested in hearing about how I use tmux then I'd be happy to write something up?

Re: [Hampshire] Tmux - the terminal multiplexer
There's zoom mode, which is really good if you use a lot of splits - you
can do {prefix}z to zoom one pane up to full screen, then {prefix}z to
unzoom it again.
Also there's text reflowing now (which screen has had for ages) - if you
resize a pane then the text inside it will reflow properly. This makes
zooming much more useful!
Also mouse support is improved - there used to be an issue (at least for
me) where scrolling up a buffer worked fine, but scrolling back down would
jump to the bottom after a few clicks of the mouse wheel; but now it works
how you'd expect. (Yes, I do use the mouse for some things, sometimes!)
(Theres more changes too, but these are the ones that stuck out for me.)

Re: [Hampshire] Tmux - the terminal multiplexer
Tim: yes. It's heirarchical - think of this as a rough analogy: Sessions in tmux can be thought of as separate terminal windows on your desktop. Windows in tmux can be thought of as tabs in one terminal window on your desktop. Panes in tmux are effectively splitting a single tab in your terminal into multiple CLIs. Each tmux window can have it's own configuration of tmux panes (which, as Anton points out, are persistent). Here's a screenshot of session [0]; window 4 (of at least 17) showing 4 panes (by the looks of it: remote tmux (showing irssi), 2 bash prompts and a music player (an mpd client perhaps?)). http://tmux.sourceforge.net/tmux5.png More screenshots here: http://tmux.sourceforge.net/ Hope this helps, Benjie.

Re: [Hampshire] Tmux - the terminal multiplexer
Interesting escape character; though I think backslash moves around too much
for me personally. (I use a lot of different keyboards!)
I didn't think I was missing anything until I started really using it either!
That's why I ask for screen features that people use that I don't; you
generally don't know what you're missing until someone points it out. When I
was younger I didn't think I was missing much using a heavily modified gEdit
for coding; but now I use Vim and know the error of my ways!
I use splits all the time, mostly for running/monitoring build tasks, workers
and test suites without either having to flick between windows/tabs or having
to give up too much screen real-estate. Shows enough information so that you
know it's working (or not!) without taking up too much space - plus I can zoom
it easily with {prefix}z if I need to see more history at once and it's super
simple to resize/rearrange/set up.
(I've yet to learn emacs - trying to get a decent grip on Vim first! I won't
start a flame war by asking if it's worth it...)
On 15 Apr 2013, at 22:09, Victor Churchill victorchurch...@gmail.com wrote:
I think this may come down to use cases and contexts. I have not made use of
the split-screen feature in screen and not missed it really: this may be due
to my desktop monitors at home being not huge (one 17, one 19) so if the
space is split it's not /quite/ big enough; interestingly I have just been on
a contract where everyone used 24 inch plus monitors and I was starting to
feel that with the extra space it could be useful.
But also I tend to do a lot of work in an emacs session where it's very quick
and easy to split and unsplit the screen. So I just run a number of
full-screen bash prompt 'windows' and an emacs one with several direds and
files (and often a shell as well) in it in separate sub-panels. ( Oh, and
btw, I configured my escape character to be ctrl-backslash :-)

Any hardware and books that aren't wanted by others would probably be welcomed by Southampton Makerspace[1]; we can't promise to be a good home but it's better than sending them to the dump. If we can't find a use for them directly (for their intended purpose) then we'll try and take them apart and make use of their juicy innards - motors, lasers, voltage regulators, connectors, buttons, etc. Plus it'd be nice for is to start a bit of a mini technical library...

Re: [Hampshire] Steam
I believe this is due to how much Valve hate Windows 8 for gaming. And it's been a much requested feature for years. I heard most if not all of Valve's own titles have been ported to Linux and many other games too, but it's still a tiny percentage of the total number of games available on Steam.

Re: [Hampshire] Raspberry Pi Questions
A loaded Raspberry Pi model B sucks down about 700-750mA, or more if you've hooked up particularly current-hungry USB devices to it. The USB specification states that USB devices should demand no more than 500mA, and many computer sockets/hubs will automatically disconnect devices that suck down more power than this - especially if the device doesn't do proper USB power negotiation. Some cheaper USB hubs (and some more expensive ones too) don't have per-socket regulation so you can suck the full 2A (or whatever they provide) out of just one, but I would not recommend it as a long term solution - the Pi is notoriously unstable when it's not connected to a decent power supply. Many computers provide more than 500mA per socket, but this cannot be relied upon. Some USB hubs deliberately have a high current port - these are normally highlighted for charging iPads and the like. Otherwise standard tablet/phone chargers that plug into the wall work quite well - I'd advise checking that these provide at least 800mA before using it. I'm using a 2.1A Nexus 7 charger for my RPi and it works wonderfully. Hope this helps, Benjie. On 5 Feb 2013, at 10:59, Chris.

Try adding .local to the existing hostnames now to invoke mDNS/Zeroconf - e.g. `ping hostname2.local` . If you don't have it installed it's just a `sudo apt-get install avahi-daemon` or similar away. When I had a Linux DHCP server at home it Just Worked(TM), but that was a few years ago now. You have to install avahi-daemon on each linux machine, it works automatically on Macs (because they invented Bonjour), and on Windows it works if you install the Bonjour tools I think. DHCP/bind integration is the better solution (and only requires software installed in one place, and only once) but zeroconf is (was) considerably easier. It may even already work!

I've since had that modem/router combo replaced with a SuperHub* * they're really not that Super, believe me. If it wasn't gigabit I'd just use it as a modem and hook the old DD-WRT router back up. -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --
Re: [Hampshire] Remote wipe of Linux systems
http://preyproject.com/ comes to mind. I agree with encryption being a better option, but the risk is if you don't shut down then your encryption key is still stored in RAM (most cold boot RAM extraction issues have been solved by shutdown scripts in the last few years, I think?) and if there's a bug in your screensaver (or whatever locks people out when you resume from standby) then they can bypass it and get full access to all your data. (E.g. Google for gnome-screensaver bypass vulnerability or, even more worryingly, Xorg screen lockers bypass vulnerability [1].) For a typical thief encryption is sufficient, but if someone is determined to get your data you might want to add additional precautions. I would never use a laptop without encryption these days - just the amount your web browser caches about you is enough to worry me about someone stealing that data, even if I never store passwords/etc. Benjie.

Re: [Hampshire] DVB Tuners
I had a MythTV system set up with 4 tuners for a long time. Unfortunately I've had to move to cable/TiVo now which means better TV but terrible interface (in comparison to MythTV). Worked fine in Ringwood, Gosport and various locations in Soton. I still have a couple on Freecom USB sticks - you're welcome to borrow them (for 6+ months) if you want - they worked under a 2.4 and 2.6 kernel but I've not tried them for a couple of years. No idea if they support HD; there was no Freeview HD when I used them. I'm in Maybush, Soton if you want to collect.

A few more data points: My parents and uncle both find it confusing still after using it for a year. The invisible menus are the biggest issue for them. My wife who is a programmer (so a little more tech savvy ;) dislikes it and finds the window grouping to be annoying/frustrating and the tray indicators to be buggy - especially with LibreOffice. I don't find it confusing but I prefer GNOME 2 considerably and dislike the left hand tray (on widescreen you have to move your mouse further too!).

Are you sure you burned the CD correctly - as an image and not just adding the ISO to the disk (you can see by viewing it in another computer - there should be lots of files - not just one)? You could try booting the Mac into target disk mode and mounting it to another computer over FireWire and installing it that way?

Re: [Hampshire] Correction - was:Re: [OT] Southampton Hackerspace Survey
The point of the survey is not to attract new members but instead to gauge the level of interest for a Southampton-based hackerspace. The survey would still be perfectly valid even if Southackton had not had any meetings or interest before this point. That being said, question 1 asks how many Southackton meetups you've attended (implying, I think, that Southackton have had meetups). The survey links to the blog[1], which has many links to further information about Southackton as a group if you're inclined to read more. We're not a recent group looking to poach members from SHH - a click on our archives page will reveal that we've been around and having meetups since 2009, and if it so pleased you, you would be able to read about these meetings (though not all our documented). Our mailing list, over on Google Groups[2], has over 150 members. I wish SHH much luck in setting up a hackerspace, the more the merrier! I think most people involved in the setting up and running of hackerspaces get excited when they see new hackerspaces setting up in nearby cities, as it allows their member bases to get together for big events, they can share technology and resources and generally do things within the hackerspace spirit; like, for example, the Brighton Mini Maker Faire yesterday. It concerns me that you feel there is competition between them - these are not commercial ventures - they are not-for-profit groups ran for the betterment of all. I think every city in the world should have a hackerspace, and I'm concentrating on trying to set one up in Southampton, where I live. If you feel I could have worded things better, are interested in a Southampton hackerspace, and wish to take part in future then I encourage you to get involved! Like most Linux developers, we don't get paid for this, we're doing it off our own backs, and this kind of negativity can be extremely discouraging. Interest, kind words, and constructive criticism can however be very motivating. Regards, Benjie.

Re: [Hampshire] [OT] Southampton Hackerspace Survey
Hi Tim, Sounds like you make some very interesting stuff! I'll certainly be sure to post here again when we're having a show and tell event if you'd be interested in presenting something you've done? Our intention is to set up a dedicated space where members can come and go as they please 24/7 (or as close to that as we can manage) and use any of the resources in the space to work on their projects or collaborate with other members. Ultimately we'd like the space to have everything you would need to create things, for example: welders, sanders, various tools, CNC machines, 3D printing/RepRap machines, soldering irons, sewing machines, a darkroom, projector, computers, cables, electronic components, etc etc etc. What we actually put in the space (if/when we get one) will depend on where the interests of the paying members lie, how much money the space has spare after rent/bills and what the space itself allows (e.g. ventilation, health and safety, etc). The space is also likely to run events such as you suggest (for members and non-members alike), and these events are likely to focus on a wide range of topics. It'll be a long time before we have anything comparable to Noisebridge in San Francisco (they have the implicit advantage of being based in tech/creator heavy San Fran after all!) but you might be interested in having a look at their site to imagine what we might offer: https://www.noisebridge.net/wiki/Noisebridge Personally, I'm interested in learning to do all sorts of electrical things (I don't know much more than my GCSE electronics taught me, and most of that I've forgotten) - especially remote control robots and (even better) autonomous ones.

They will also know that I mess about with boats (model and full-size) and aircraft (model only). So you would be right in thinking that I would be interested in meeting to discuss ideas; in fact, that's what I do at HantsLUG meetings, I'm just a bit selective about my subject matter to avoid boring the pants of everyone in the room. Now, the small problem I have is that in order to achieve most of the projects I undertake is the multi-disciplinary nature of the stuff I do. It tends to involve a lot of detail in both soft and hard engineering, and a massive investment of time. A model build taking a few months is not unusual. The problem, however, is only partly time (and cost of attendance). I think a lot of us can handle a once-a-month meeting, but more often just wouldn't be possible. The real problem comes in terms of the disperate nature of tasks that people would be interested in undertaking. Is it going to be focussed on robotics? UAVs? UUVs? Home automation? and what tooling do you need to achieve that? For my current project, I'm on basic electronics, composites and computer aided design! So, I would like to make a suggestion. When a request for talks is published, think whether you could give a talk on the project you're currently doing. There are a lot of people on the list who can advise on (and are interested in) disciplines other than Linux on servers. Personally, I would like to see LUG members bring more than just soft topics to talks. The hackerspace serves a different purpose to the LUG, but not everyone might wish (or need) to join a second group.

Re: [Hampshire] Support for touchscreens
That was my first thought too, but I'm not sure how you'd go about remotely administering an iPad - I guess you could jailbreak it and install a VNC server of some kind. For remote administration I suspect Linux'd be a better bet. That being said, what do you really need to administer? Buttons on iPad are big, clear and most importantly for someone not so computer-literate the interface across most apps on the platform is very consistent. They only have one hardware button they need to worry about. There's all sorts of very well implemented assistive technologies in the iPad, too. Benjie.

Also, think carefully about fully replacing your desktop entirely :) both have a 15 screen, which can be quite small if your use to larger and the keyboard and mice can get annoying for intense use (though this is down to personal preference, its just something to make note of). Personally I like having a very powerful desktop (which are generally have a better cost to performance ratio and easier to upgrade) and a low spec'd laptop for when I cannot use my desktop (which is quite often). One hidden advantage of not relying on a laptop is that its not a huge loss (assuming its all back up properly) when it gets damaged/lost/stolen, which laptops have a tendency to do more often then desktops. And as for benchmarking, it highly depends on what you want to do as different computer will come out top on different benchmarks... I find they are only useful if your looking at a particular aspect (ie you want to know how good it is for doing X and only really X). Just for comparison, I have a ASUS 1018p 10 netbook [1] as my mobile computer, and find it is capable of doing just about everything I need it to when away from my desktop. This includes programming and compiling, even running the occasional virtual machine. The only think I found it lacking in is its graphical capability which is more then made up for by it being small, light-weight and having large battery life.

I am off to the ski slopes shortly, and access my slingbox from Switzerland as most hotels have limited UK TV. I can access it from my Galaxy S11. Hi Mike, I'm not sure if it helps with your slingbox situation, but the Tivo has a very simple (and reliable) network remote control protocol - just enable it from your Tivo settings and then telnet to your tivo on TCP port 31339 and issue IRCODE SELECT. This even allows you to put the tivo to sleep and wake it from sleep.

No problem, thinks I, I'll just update to 11.10. I have done so, and Unity issues aside (I've installed GNOME Classic for them now) it's gone well... EXCEPT the computer only boots roughly 1 time in 3 (no obvious pattern). The issue, I've found, is due to their RAID0 /home partition not initialising correctly sometimes (sometimes it's degraded mode, sometimes no message at all, it just locks up). I've had a good poke around and it seems that it doesn't work when /dev/sdb is detected as /dev/sdf instead. I know this in itself isn't a bug, but it seems to be what is causing the issue. I was expecting it to Just Work (TM) since it does for all the other boxes that I have RAID on. I thought the persistent superblock should stop this issue from happening, but autodetection seems to be failing early during boot. I've added relevant data to the bottom of the email to rule out some common issues/confirm what I've done/point out an obvious issue I may have overlooked... For autodetection I require, according to http://tldp.org/HOWTO/Software-RAID-HOWTO.html#toc7.2 1) Autodetection in the kernel [I have stock Ubuntu 11.10 kernel - perhaps this is missing/missing from the initrd] 2) Persistent-superblock [mdadm claims this to be the case - see below] 3) 0xFD partition types [fdisk claims this to be the case] From /var/log/syslog (or /var/log/messages) we get: Dec 26 09:12:15 ann-desktop kernel: [3.251290] md: bindsda5 Dec 26 09:12:15 ann-desktop kernel: [3.290692] md: bindsdb5 Dec 26 09:12:15 ann-desktop kernel: [3.293935] bio: create slab bio-1 at 1 Dec 26 09:12:15 ann-desktop kernel: [3.294070] md/raid1:md0: active with 2 out of 2 mirrors Dec 26 09:12:15 ann-desktop kernel: [3.294097] md0: detected capacity change from 0 to 151846780928 Dec 26 09:12:15 ann-desktop kernel: [3.296464] md0: unknown partition table This suggests to me that auto-detection is not occurring, so installing something (kernel modules/settings/app/whatever) and then doing update-initramfs -u should presumably fix this issue, but I've not much longer to solve it before I leave to go back home tomorrow. Any ideas would be greatly appreciated. Further details follow. I hope you're all having a great Christmas! Happy New Year!

Re: [Hampshire] Max OS HD image
TestDisk does exactly that - it scans the whole disk looking for pieces of data that look like they were JPG images (or whatever you're searching for - it has a bunch of prebuilt filters) - which is why I recommended it. However different filesystems lay out files in different places - e.g. at multiples of 512bytes or other such things, but TestDisk might not have the rules for HFS+. I suspect it will do its best nonetheless, which is why I suggested it. I've used TestDisk against both raw devices and dd images of devices before - it should do what you want without having to mount the image. The mount command was just in case you needed it, I'm sorry it confused my post. Cheers, Benjie.

Re: [Hampshire] Data Destruction
I'm not sure the TrueCrypt solution will work. Normally when you create a filesystem/partition, the tools write out the minimum data they can - generally the partition layout in the MBR and the file allocation table at the beginning of the disk (and in a number of backup places throughout the disk in the case of ext3/ReiserFS/any decent modern filesystem). Formatting your drive rarely overwrites all of the data on the drive, it just leaves the file data intact and marks those regions as 'unallocated' so that the system doesn't get confused. TrueCrypt /might/ overwrite the whole drive, but I certainly wouldn't take it for granted - it's intended to protect the data contained within the new filesystem, not the data that was there beforehand. Generally you can tell by how long it takes to format the drive - assuming a sustained average write speed of 150MB/s it would take almost 4 hours to fully overwrite a 2TB drive - with encryption this is likely to take even longer. You could of course create the TrueCrypt partition and then fill it up 100% with whatever data you want, e.g. dd if=/dev/zero of=/mnt/truecrype/file, but this would still leave one piece of data on the drive - your TrueCrypt password - so be sure to set this to something you don't use for anything else ;) I doubt anyone has the resources to use an electron microscope to partially recover some of the data from your drive for teh lulz, so unless you have something serious to hide I'd suggest that just overwriting the drive with zeros using dd is perfectly sufficient - this should erase the MBR and partition layout too, not just the data on the partitions. If I was really worried then I would then smash the drive with a lump hammer to necessitate physical recovery. You are talking about a semi-modern HDD - not a 256MB one - right? Cheers, Benjie. PS: A quick glance at the TrueCrypt 'beginners tutorial' has this note (relating to creating a filesystem in a file): IMPORTANT: Note that TrueCrypt will not encrypt any existing files (when creating a TrueCrypt file container). If you select an existing file in this step, it will be overwritten and replaced by the newly created volume (so the overwritten file will be lost, not encrypted). You will be able to encrypt existing files (later on) by moving them to the TrueCrypt volume that we are creating now.* -- Please post to: Hampshire@mailman.lug.org.uk Web Interface: https://mailman.lug.org.uk/mailman/listinfo/hampshire LUG URL: http://www.hantslug.org.uk --

On 7 Oct 2011, at 09:05, James Courtier-Dutton wrote: If you really have to erase all trace of the data, you should really have thought about that before writing it to the HD. Normal practice now is to use whole disk encryption. Then, to erase the whole disk, just erase the key. That's a valid solution, but not a hugely secure one: since the layout of the filesystem is quite predictable in places you can use this knowledge of the crypted data to help you break the encryption, the only requirement is time. Other weaknesses include key backups and weak passwords. There's also high resource attack methods round the corner such as quantum computers which should be able to decrypt most encryption very quickly. Or even GPU farms which are easily rentable on Amazon's EC2 by the hour, here's some software you might use to break the encryption using these: http://www.elcomsoft.com/edpr.html Personally, I'd dd if=/dev/urandom of=/dev/sda even though I have full disk encryption enabled, you never know what's round the corner.

Re: [Hampshire] DDoS survival strategies
Other issues with this approach: - Proxies would route lots of traffic through few IP addresses - Large campus networks (e.g. universities) sometimes use single outbound IP addresses - If you export APIs, these may be being polled too frequently accidentally - External services which fetch from/aggregate your site - Extremely large DDoS with low per-client connections would not be detected - It might not be clear why your server is responding to some people but not others 2 years down the line One thing to mention with IPv6 is that the namespace is /FAR/ larger than IPv4 (10^29 times as big, roughly), so internet wide scans will no longer be feasible based solely on incrementing IP addresses (they could filter it down by only the assigned IP addresses though, but that's still a pretty large namespace).

One way to deal with this is to have a 'panic button' script which you can hit and it forwards all requests to a static copy of your site hosted on a large CDN such as Amazon S3.

One of the great things about screen is you can set it up as the remote command for when you SSH into a box, so you always continue where you left off (very useful if you're connecting from your phone or from anywhere over a 3G/EDGE/GPRS/packet radio/... network). Also you can set up a configuration so that certain screen numbers run certain commands straight away. I've even used screen to run server software I'm developing before it's ready to properly daemonize - better than having to tail a log file - you can use terminal control characters (is that what they're called?) to better output what's going on without giving you information overload. I highly recommend that you do not sudo su or su from inside screen and then disconnect... quite a security issue...

Re: [Hampshire] [OT] Network Query
My suspicion is that powerline is dropping or corruping a bunch of packets and so you have a high retransmission rate clogging up your network port.

Re: [Hampshire] confused ssh newbie
Can you ssh -p from another computer/device on your LAN? (You may need to use your internal IP address to do so.) If so then you at least know SSH is working. If not, then I'd use netcat. is an unprivileged port (1024) so if you shut down sshd you should be able to run nc -v -l -p on the server. Then from another computer/device run nc -v [your ip] Anything you type into one should show up on the other after pressing return (netcat is line buffered). If it doesn't then the debugging info netcat outputs may be useful in diagnosing your issue. What is the output of the following command with sshd running? sudo netstat -pant Kind regards, Benjie.

Re: [Hampshire] Home network cabling
You could also run the cable through pipes outside, fit a junction box to the outside wall of your house. I'd use a switch in room A (they're very cheap and relatively power efficient) and just have one cable from central hub. Allows for better future expansion too. If speed isn't an issue then you could look into using HomePlug adaptors - works fine for my parent's iPlayer on Freesat box. http://en.wikipedia.org/wiki/HomePlug (they can be quite fast in the right circumstances, but I'd definitely opt for cat5e in my bandwidth hungry and latency sensitive household).

Re: [Hampshire] Networking for Dummies
Eclipse used to do multiple IP addresses, I don't know if your ISP does. If so, you could do this with 3 devices: ADSL router and 2x ethernet routers, then you set up 2x standard NAT one on each IP address. That'll safely separate the networks. Benjie. On 9 May 2011 16:43, Vic l...@beer.org.uk wrote: If you connect the 'internet' side to the ADSL router you effectively put anything connected directly to the ADSL router into a sort of DMZ (sort of since it is still firewalled as normal, so not really a proper DMZ) with a separate IP address range that is firewalled off from the rest of the network by the cable router. Errr - I'm not so sure about that. What is behind the cable router has the usual NAT blackhole, but what is hanging off the ADSL router is entirely unprotected from what is behind the cable router. So if the untrusted box is the one behind the cable router, all the trusted boxes are still subject to attack from the problem box. And that box has essentially unfettered Internet access, so it has no protection from PEBKAC either. You could, of course, have it the other way round - but that means reconfiguring everything currently on the network, means that those boxes will have to deal with double-NAT (which may or may not be a problem), and still offers no firewall filtering for the hostile box. So I don't think I agree with you...

Re: [Hampshire] Setting up ATI Mobility Radeon HD 4200 in Debian
You probably want to fully uninstall the existing drivers before installing the new ones.

Re: [Hampshire] Domestic ADSL ISPs

It was 50GB limit during the daytime, unlimited overnight. I'd still be with them now if I hadn't moved to a cabled area. I'm with Virgin Media now - 5MB upload makes such a difference to my work-flow (I work from home). 50MB download is great, but it's the upload I really notice.

Re: [Hampshire] Interesting DNS problem
You could use Amazon AWS' Route 53 DNS hosting and use the APIs to update
the domain name directly, that way you can update the root record to be an A
record pointing to the dynamic IP and instead of the dyndns script have a
route53 script which updates Amazon's nameservers.
http://aws.amazon.com/route53/
http://aws.amazon.com/route53/It's not free though: $1/mo plus $0.50 for
every million requests. So probably less than £10/year for a very low
traffic server.
But to be perfectly honest, I'd take your solution, Adrian, and have a
friendly host redirect for example.com:
RewriteEngine On
RewriteRule .* http://www.example.com%{REQUEST_URI} [R=301,L]
