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.

O.T. Problems with USB sticks
by Chris Walker 11 Feb '15

11 Feb '15

I have a few USB sticks which I use in my car to allow me to listen to things like iPlayer downloads. But only one of the three is recognised by the car now. I've reformatted them under both linux and Windows 8.1 on my wife's laptop but the problem persists. The thing that the two 'failing' discs have in common is that I have also in the past used them on my tv to record stuff. The tv reformats them to NTFS whereas the car expects them to be FAT32. Are there are utilities I can use to see what might be different between the various sticks? For info, one of the 'failing' discs is of the same type as that which *is* recognised in the car whereas the other disc is an almost new 32GB stick from Maplins. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Any VNC experts here - I can't get it to work at all
by Chris Green 10 Feb '15

10 Feb '15

I am trying to set up a Raspberry Pi (running Raspbian) as a remote display using VNC. I.e. the Pi will be a 'listen only' client and my laptop is the VNC server. I'm getting absolutely nowhere! :-( I have installed the TightVNC bits at each end, that's tightvncserver on my xubuntu laptop and xtightvncviewer on the Raspberry Pi. I have tried two ways to get this to work, first the conventional way:- Run 'vncserver' on the laptop, this appears to run OK and ps shows an Xtightvnc process running. Then run 'vncviewer x201' on the Pi (x201 is the name of my laptop), it just says "vncviewer: ConnectToTcpAddr: connect: connection refused. Unable to connect to VNC server" Alternatively try getting the client to 'listen' for a connection:- On the Pi run 'xvncviewer -listen -fullscreen' and 'vncconnect tvpi' on the laptop (the Raspberry Pi is called tvpi). Nothing happens at all, just silence. The two machines can definitely see each other, they're on the same LAN and I can ssh back and forth. Help!! -- Chris Green

Wanted - decent interface for viewing pictures
by Chris Green 09 Feb '15

09 Feb '15

For the umpteenth time when we recently looked at some pictures I decided the 'media centre' way of looking at them is truly awful! I have my digitised photographs arranged the way I want them in a hierarchy of years/months/days with descriptions in (most of) the folder names. So when I view them I want to be able to use the hierarchy to navigate easily. We have a WD TV Live media player which is quite well thought of in reviews but it makes viewing pictures a real chore for a number of reasons:- It's slow by design because of the way it fades from one image to the next, thus you're never quite sure if you really have clicked on the '>' button or not. It hides the hierarchy above the current directory so you have to navigate by memory basically, or go too far up and then down again. No image manipulation at all, you can't zoom in for example. There's no way to jump to the next folder/directory in sequence, i.e. if I have just looked at 1973/04/07 I want an easy way to go to 1973/04/08 but I can't. The other 'media' software have seen (we have another make of media player where my wife stays during the week, also built-in TV apps) is no better as far as I can see. So, what I suspect I want is an easy way to use the program(s) I use on my Linux desktop (or laptop) directly on the TV screen. I could dedicate a system to the TV but this entails either leaving it on permanently or waiting for it to boot every time one uses it. A Raspberry Pi is a possibility, leaving it on is then not an issue but there are downsides like will it be fast enough and it needs a keyboard and mouse. Another fundamental problem is that whoever is managing showing the pictures needs to be close enough to the TV screen to read text and that's likely to be too close for comfortable viewing and/or sociability. So on to my final idea, use a laptop with the TV as a remote display. The viewing software runs on the laptop and the person running it can use the laptop keyboard and touchpad/mouse to control things. The only issue is handling the dual display, has anyone got any advice on this front, e.g. ways to have different views on two different displays, etc. -- Chris Green

File manager with preview
by Mark Rogers 08 Feb '15

08 Feb '15

Somewhat prompted by Chris's picture viewing enquiry but sufficiently different to warrant a separate thread. I'm looking for a file manager for viewing directories in my PC, which as a decent preview feature. Ie typically I'd like to see a directory tree in a left pane, the file list in a middle pane, and a preview of the currently selected file in the right pane. Of particular interest is having the preview work on as many different file types as possible. Images obviously, but also PDF, .odt/.doc[x] etc. Background: It's for my wife (a bookkeeper). She has directories of files which are receipts in various formats (scanned images, PDFs, emails, etc) and for the purposes of entering them into an accounts package she often just needs a cursory glance at the file content to get at the date, value, and a general idea of what it was for. At the moment she's spending more time opening and closing documents than she is doing anything else. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

DHCP failure after BIOS clock reset
by Mark Rogers 08 Feb '15

08 Feb '15

I have a little (headless) ARM box running Debian with a built in clock module, but whose battery had died. On replacement the box failed to get an IP address via DHCP. On investigation it appears that because the clock was "wrong" it couldn't perform DHCP queries ("Unable to setup timer"). I think "wrong" doesn't just mean inaccurate (it was claiming to be in 1928) but corrupt (hwclock reported corrupt registers). The clock would get reset by a time server as soon as it got online, but without valid clock it couldn't get online to get the valid clock... Anyone know any more about this or able to point to a general workaround for next time this happens? All I have found (after the event) is here: http://www.solid-run.com/community/viewtopic.php?f=8&t=525 .. which confirms what I thought but doesn't really offer a solution (logging in to set the clock on a remote headless unit isn't particularly convenient!)

Linux Mint 16 & Lenovo T520 Track Pad
by Paul Grenyer 07 Feb '15

07 Feb '15

Hi All I've a Lenovo T520 with Linux Mint 16 installed. It's been working perfectly until a few weeks ago when the track pad stopped working once I log in. After googling I've found a few people with the same problem but the solutions are a bit hit and miss and it never stays fixed after a reboot. Can anyone help, please? -- Thanks Paul Paul Grenyer e: paul.grenyer(a)gmail.com b: paulgrenyer.blogspot.com t: pjgrenyer Have you got your ticket for NorDevCon yet: http://nordevcon.com Have you thought what Naked Element could do for you? http://nakedelement.co.uk/ It's time to get technical: http://norfolkdevelopers.com

OT- Contract to manage RHEL VMs
by mick 06 Feb '15

06 Feb '15

Please forgive the OT nature of this request - or shout at me if you like. :-) An old friend of mine who works in IT procurement has just asked me if I could recommend a local company capable of bidding for a managed service covering some 250 RHEL VMs spread across about 50 physical hosts in various locations. The contract is to cover: packaging, deployment, acceptance testing, and production of services on Linux VMs; 1st line support and triage for all Linux VMs; 2nd line Linux VM software engineering support; patch control and management of Linux VMs deployed across the network. The systems are all RHEL and use NAGIOS, Puppet and a Ticket System called OTRS. He has given me a 20 page extract of the Procurement Requirements document which gives full details of what they have and what they are after. I know that there are subscribers to this list who work for companies capable of doing this but rather than spam the list unnecessarily, if anyone is interested please contact me off-list and I will forward the details. Thanks in advance.
