ALUG Announce Please send announcements to Announce(a)lists.alug.org.uk Unsub, change settings via http://lists.alug.org.uk/mailman/listinfo/announce ----- Hello Norwich Aluggers, Our monthly ALUG Norwich social meeting will be held this Thursday, 12th May at The Coach and Horses (82 Thorpe Road, Norwich, NR1 1BA). 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. Optionally you could ask at the bar if they know where the geeky computer weirdos are and they'll point you in the right direction (seriously!). 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.

An old problem - how to manage permissions with web servers
by Chris Green 07 May '16

07 May '16

I'm always hitting this problem in one way or another and I've never really come up with a good solution. I have lots of personal information (not secret, just that it's mostly only useful to me) which I keep in a Wiki. To make my life easy I run apache2 as user 'chris' (me) on the servers where I have the wiki. This allows me to edit pages directly and do all the maintenance etc. without the rigmarole of becoming root and/or becoming www-data. However this then causes problems with other stuff that runs under the web server as they assume that it's going to run (in Ubuntu anyway) as www-data. My current hassle is with Owncloud which installs with www-data owning the data directory and I have to manually change the ownership to allow it to write. There are also other similar conflicts. Isn't there a way to tell the installation system that I want my browser to run as a specified user rather than the default (and really annoying!) www-data? I suppose I could bodge /etc/passwd so that chris and www-data are the same but it is rather a bodge, I'd like a better solution. -- Chris Green

What permissions will apt use when installing? Will umask affect it?
by Chris Green 06 May '16

06 May '16

I want to be able to install a web app with a umask of 0002 rather than the default 0022. I have worked out how to get the www-data user to have a umask of 0002 when used by apache but I'm not sure how to *install* the app with the required permissions. It's being installed and kept up to date by using the standard apt in Ubuntu (it's on a PPA). Does anyone know if it's possible to tell apt to use a different umask? I.e. if I set the umask when installing will I get the effect that I want or does an application installed by apt set its permissions by configuration somewhere? -- Chris Green

Ubuntu updates
by Bev Nicolson 06 May '16

06 May '16

On 12.04LTS but get security updates almost every day and I guess on the one hand that could be encouraging, on the other, I do start to wonder why they don't all arrive at once. (I know now. It's how it connects to the internet.) Is there any way of asking Update Manager to show them every fortnight instead? I can’t see that option. Ta. I'm on a limited broadband band deal during peak hours so saving them up would be useful if possible. Bev.

Wanted: Non-realtime but automatic file synchronisation
by Chris Green 06 May '16

06 May '16

I have a number of large[ish] directory trees that I would like to keep synchronised across various systems. There are basically three systems involved: desktop, laptop and a remote server. They all run Linux (xubuntu and ubuntu). I don't need real-time synchronisation like that provided by btsync, syncthing or pulse. The directory trees are really too big for this sort of thing anyway. On the other hand I don't want a manual system like Unison which anyway seems beset by problems with different versions at each end. All I want (all?) is a way to keep the directories in sync when changes occur at either end. Since the changes will be mostly generated by me it will be very rare for changes to occur in two places at the same time. If they do then I'm quite happy for the system to require manual intervention. I just want the general case to be automatic. Updating once an hour or so would be quite satisfactory. I can do much of it using rsync with the --update option run first one way and then the other, this does nearly everything I want but there is one gotcha - files deleted will re-appear. File deletions will not be frequent but they will occur occasionally. Adding a --delete option to rsync doesn't necessarily help, it could also mean that new files added get deleted. It all depends on the relative timing of additions and deletions and the copying each way. Nearly all the 'directory synchronisation' tools I can find are one-way and do very little more than one can do easily oneself using rsync. Has anyone come across anything that might do something like I want? -- Chris Green

Starting a web server on demand - sensible, easy?
by Chris Green 06 May '16

06 May '16

I want to run a Javascript/PHP application on my laptop which will at times be unable to get to the internet. Thus I need to run a web server of some sort on it to serve the PHP side of things. If the laptop is at home on the home LAN I want to be able to run the same Javascript/PHP application on my desktop machine so I can use the bigger screen etc. This will work fine of course with the web server on the laptop, as long as the web server is running. What's the neatest/easiest way to fire up the web server on demand? I don't really want to run it all the time. Ideally also I'd prefer not to run Apache as it's total overkill for what I'm doing. I tried PHP's built-in web server ("php -S localhost:80") and it works fine for me, the home LAN can't be accessed from outside so security should be OK. I suppose the modern equivalent of inetd would do what I want but I'm a bit worried about how easy it might be (or not). -- Chris Green

Desktop PC spec for virtualisation and transcoding
by Mark Rogers 14 Apr '16

14 Apr '16

I'm looking to replace my home desktop PC (Ubuntu) with something a bit better. Budget around £4-500. It mainly runs a couple of virtual machines (VirtualBox) and acts as a media PC with Plex (which means video files get transcoded on the fly, which includes some 3D HD titles). Both of these are areas that the current PC struggles with sometimes (A8-6410 CPU with 12GB RAM and SSD). To be fair it copes with everything now as long as I don't try to do both at once but if I watch a 3D title I have to shut down all the VMs, and any more than a couple of VMs at the same time will push it. I got a good deal on a 500GB Crucial SSD so that's prompted me into building a new box around it and the forthcoming Ubuntu LTS. I found some desktops based around an i7 and 16GB which is the direction I'm heading in at the moment but I'm open to suggestion. I assume the graphics capability is of some importance for transcoding, is Intel on-board enough? (I won't be playing games.) I'm happy to build for myself although for a modest premium would buy pre-built (no need for Windows though!). -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Ghostery and Adf.ly
by Chris Walker 13 Apr '16

13 Apr '16

I keep getting tabs opening up in Chrome with a URL of Adf.ly but can't find it in the list of extensions. So I thought that if I search my machine for that string I might be able to find it and delete as I am irritated by the constant appearance. A search revealed that a Ghostery database file contained that string. So if I want to stop Adf.ly being presented to me every time I run Chrome, should I simply delete appropriate section from the Ghostery database? Or is there a better way? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|
