[Hampshire] VLC on Ubuntu not playing some DVD VRs
Hi all This might sound like an old chestnut but I'm fed up of googling because it is qutie "subtle" I have some home-recorded DVDs (converted to ISO) which won't play on VLC on Ubuntu (Jammy). VLC opens and crashes immediately. The trouble is: * The same files play fine on VLC on both Mac and Windows * Some other home-made DVD ISOs play fine on Jammy. It may be that I recorded the working ones with one DVD recorder and the non-working ones with another DVD recorder. Come what may - both Mac and Windows will play all of them. I've run vlc from the command line and I get the error below. It looks like it's something to do with a locale. FWIW I've changed the output between wayland on gnome and X11 - but neither works.

[Hampshire] Detect USB or SATA drive
Hi all I need a bit of help identifying drives that I (stupidly) didn't put a sticker on before I initialised them. I have about 6 drives connected to my media server. 2 are inside the case connected by SATA (1 is the OS (Xenial) and the other is media). Then there are 4 connected externally (in one 4 bay das jbod). It would be useful to me if I could determine (via df -h if poss) which are usb and which are usb. I've tried lsusb and lshw -C disk but neither are helping. lshw keeps telling me they're all SCSI for example which I know is wrong. They're all SATA - it's just that some are connected via USB, some aren't.

[Hampshire] [OT] Annoyance - Windows Sound
Hi all I have a /* not wishing to tempt fate */ stable /* end of wish */ Windows machine which works in every respect other than it intermittently has a problem with cracking / delayed sound during heavy disk access. Try listening to music and looking at ebay concurrently and it's very annoying. In all other respects the box is fine - albeit approaching 5 years old. Not being a gamer - I've no real need to upgrade - so the cost of the upgrade itself + MS Office (required for work) + my magnification software is non-trivial. Apparently this is a very common problem but most searches I've done suggest a driver issue - but I've tried all these (including using a sound card as opposed to onboard sound) and same issue pervades so I can't see how it can be a driver issue.

[Hampshire] 9-pin dot matrix printing - golden oldie
Hi all Anyone know / remember how to configure a 9-pin dot matrix printer with lpr on a modern distro (e.g. Ubuntu)?

I have it printing "graphics" fine via CUPS but it's printing everything (even lines of code) as graphics - so it's very slow.

[Hampshire] From ADSL to VDSL (BT Internet)
Hi all I've been offered a free (completely) upgrade from BT ADSL "Total Broadband" to "BT Infinity". As 0 extra cost - why wouldn't I (That's a rhetorical question - not the one I seek answers to!) As part of the agreement over the phone I was told my old BT Hub would be replaced. but this has got me thinking. At present, my master socket (dining room) has an extension into the study so I can make phone calls from the study. Into the study's extension is plugged a phone and an ASDL micro filter. The BT Hub is plugged into the ADSL micro filter in the study. BT tell me that the new router they're sending a)Simply replaces the existing router (so would be plugged into the ADSL micro filter in the study) b)That I can connect this new router as soon as it arrives. I'm not sure I believe this. I was told that VDSL modems need to be connected to the master socket - not an extension. As such, I'll need to uninstall the router in the study and put the new router directly into the master in the dining room. Does anyone know definitively?

[Hampshire] [Golden Oldies] Solaris Boot Order
Hi all Does anyone know how (without a serial link or proper Sun keyboard) to interrupt the boot process on a Sun Blade 150 (openboot)? My machine (bought for pure nostalgia) is either looking for a network boot (if I disconnect my only IDE HDD) or boots from said IDE HDD only to infinitely loop. This is because I got so far installing Solaris from CD before it would go no further without a network. This was an NVRAM issue which Ive now fixed. Clearly I either need: a)A Sun Keyboard with a Stop key these are going for £40+ - too much for a keyboard when (for all other intents and purposes) a standard USB keyboard would work. b)A usb 9 pin serial cable c) To wipe the IDE HDD outside the Sun Blade. Trouble is (sods law) my only IDE HDD caddy has given up and wont power the drive despite it working find on SATAs. Again why throw good money after bad by buying an IDE HDD caddy (£20ish from China is cheapest I can see). Bluntly if anyone has a)A sun keyboard or b)A usb to 9 pin cable or c) A ide hdd caddy that they no longer want please contact me off list and Ill pay shipping. Other than that - any ideas anyone?

[Hampshire] Rogue Drive Errors
Hi all I can't explain this - perhaps someone else can. I have a 2TB 3.5" ext4 formatted internal drive (bought only in December) which was reporting errors yesterday. At the time, it was connected via USB Icybox JBOD and threw out more "short read" errors than I could count. I left it running e2fsck -y /dev/blablabla overnight and it was still reporting errors this morning. Getting fed up (and not wanting to write the unit off), I did mkfs /dev/blablabla and when I fired up rsync again - same type of IO errors. At this point I wrote the drive off and used a spare for my purposes. Curious to see if I could get any more information from the failing drive, I then moved it into a USB docking station on a different machine. Running e2fsck again and I got a clean filesystem (no new formatting or anything). Worried that this meant the drive was fine and potentially that particular bay in the (4 bay) Icybox might be the culprit, I moved the rogue drive back into the JBOD (same bay) and guess what - clean bill of health from e2fsck. So in short I have the same drive reporting errors, reformatted reporting errors, physically moved clean, then physically moved back clean. I've never been too hot on the rather low level way Linux handles disks - but I do want to know if the effing thing is good to use or not. Is a clean e2fsck result good enough? If so, were the hundreds of errors it was chucking out safely ignorable?Have I missed anything obvious?

[Hampshire] Minidlna
Hi all Has anyone had any success running minidlna? For the life of me, I can't see what I'm doing wrong. It's installed and according to sudo services minidlna status it seems to be running ok but I can't see it either on the server's file manager (which is Xenial) or on any (Windows) clients. Disconcertingly, it doesn't even appear to be building a database or logging to anywhere. I have faffed at length with /etc/minidlna.conf but to no avail. Apparently you can either run it as yourself, and ensure minidlna.conf is pointing at directories that you have write permission to. The alternative (and default) is for it to run as a (non-logging in) user called minidlna. In this case, said user minidlna must have write permissions to all directories specified in minidlna.conf. Not wanting the hassle of chmod hierarchies, I went for the former option and specified it as such user=myname in /etc/minidlna.conf. Is there a winning formula out there? The reason I'm trying to set this up is I rather fancy [2] and sadly it only works with dlna.

[Hampshire] USB devices power down
Hi all When "should" a USB device (an Icybox JBOD 4 bay DAS in this case) power down? Most (ymmv) USB devices (keyboards, mice etc) are powered from the host if they're not powered from a powered hub. Last night, in response to the recent samba vulnerability [1], I patched then powered down my media server. I left it off overnight as I was too tired to do any sort of testing. This morning, it wouldn't boot to GUI and the logs were telling me it was a USB device fault. Turns out the Icybox (whose drives are referenced in the server's /etc/fstab) was off. Powered the Icybox back up, rebooted the server and all is well. However the Icybox has its own power supply. So I'm wondering why (when it doesn't have any settings/ drivers - the only controls on the front are for fans) - does the unit power down? Is there anything I can do about it - I've never been too hot on low level device handling in Linux.

Re: [Hampshire] DAT as a backup medium
I agree with just about everything that’s been said – though prior to one of the replies I didn’t know what an archive disk was. The problem for me is a)Cost b)Durability Agree that HDD should last for a few years – but we’ve all seen hdds fail. From what I’ve read, unless you can spread your backups across sites (which may be an option) but tape seems the most durable solution – optical disks are nowhere near reliable for data you don’t want to lose. I find it amazing hdd technology (which we’ve has since the 70s) is still the medium of preference. When someone finally does crack this (I guess when SSDs do finally take over in terms of capacity and price) we’ll all look back on HDD as rather primitive.

[Hampshire] [OT] Hardware : Old PC, new hardware
Hi all I'm thinking of resurrecting an old PC for retro gaming. Before I get going, need a few questions answered. I have such a machine (P-IV, 512Mb RAM, decent enough graphics) but it's circa 2004. 1)I've not powered it on in years, but the CR2032 mobo battery is almost certainly dead. Is it a question of just replacing it - or are there better solutions out there nowadays? 2)Is it likely to be a standard battery or do they vary by mobo? 3)I think it has SATA and IDE so I'm going to replace the HDD with an SSD. Any issues here? I've heard some BIOSes complain about the side of the HDD inside, but if we're talking SSD, then 128Gb will be all I can afford so even in 2004, 128Gb wasn't too big a BIOS was it? Any other considerations (VGA to HDMI in DOS mode games)? I think I still have the Windows XP CD and the license no is still on the box. Might have some fun activating it!

[Hampshire] HDDs and UUID
Hi all (sorry for various tests, had forgotten which email account I use to subscribe to this list) At present, I have a (3.5" sata) drive connected to my Ubuntu machine via one of those docking station things - I couldn't be bothered opening up the case at the time and as it's only a media server, I thought no more about it. Now I'm considering buying a 4 bay JBOD enclosure and I'd like to move the drive into that. At present, the drive is mounted via putting its uuid in the /etc/fstab. Simple question (which I know I could work out just by swapping the drive but please humour me): if I swap the drive out of its caddy and put it into the jbod, will it still be noticed. The question I'm basically asking is : Is the uuid associated with the drive unit or the controller in the caddy? Cheers all - long time no post - very long story I won't bore y'all with.

[Hampshire] NAS permissions
Hi all Happy New Year - my first post for a while. I'm having a bit of trouble setting permissions properly to mount a NAS device as read write for a given user. It's a brand new QNAP TS-412 and seems to be a little Linux box with a nice graphical UI. Surprise, surprise, connect via Windows and I can move, read and write with no user or permssions problems. If I then do: sudo mount -t smbfs //sharename /mnt/abcd -o user=fred then I can get read access to the mount point - but neither sudo uname -a test or uname -a test in /mnt/abcd produce anything other than permission denied. I've never been too hot on umask and permissions but a quick ls -l /mnt gives: drwxr-xr-x 1 root root0 Dec 22 14:51 abcd and even chmod a+w /mnt/abcd doesn't make a difference. It must be something easy - because if I connect to it via gnome Connect to Server - no worries - full rw access. Can anyone help please? - this is driving me nuts.

Re: [Hampshire] NAS permissions
Hi all Thanks for this. I switched to cifs and am still getting problems of permission denied. 2 questions: 1) Once mounted, do I have anything to worry about with the permissions of /mnt/abcd or anything beneath /mnt/abcd or is this all handled by mount? 2) Linux is connecting to this via cifs, whereas I have full rw via Windows as the same user - so am I tight in thinking it can't be a user permissions thing. 3) Another issue is I can create a file by copying i.e. the following works: sudo cp /mnt/abcd/foo /mnt/abcd/bar as does sudo rm /mnt/abcd/foo but sudo uname -a /mnt/abcd/xyz fails with a permission denied.

[Hampshire] Legacy ide
Hi all Another question demonstrating how out of date my knowledge is. Just bought a new mobo but forgot that the case into which I'm putting it has a perfectly working DVD-ROM ide drive. The mobo has no such legacy connector. To be honest, I don't particularly need the dvd drive and have installed the os from a pen drive but to get the DVD back up again - what's the best approach here? 1) Get a sata dvd drive - slightly defeating the object! 2) Get an IDE controller card. If so, anyone know how easily these things integrate with Linux? Being so low level I'd assume it would work out of the box but you never know. 3) I've seen IDE to SATA adapters for about 7UKP but as this is parallel to serial (isn't it?) would there not be driver issues here? 4) Get an IDE to USB adapter - but I can't see a usb socket on my new mobo so presumably the data cable would have to come outside the case to connect to a usb socket wouldn't it?

[Hampshire] ufw
Hi all In short - do I need to reboot to force ufw to apply any changes I've just made? I'm playing around with ufw on my Ubuntu box which is now my media server. I'm trying to get it to connect with my Netgear NeoTV underneath my tv but seemingly only disabling ufw entirely works. The Neo either refuses to see the box (and can't connect directly i.e. can't connect to anything it doesn't see) or sees the machine but then asks for a username and password (which aren't required to connect to the same samba share from Window$ boxes). What I need to know is does sudo ufw enable do everything I need after I've changed rules. It seems I need to reboot the Ubuntu machine and or the NeoTV each time. I'll worry about the Neo thing last but if should (for example) be restarting samba, restarting networking or restarting something else, it would be great to know - I've not seen anything to this extent on the web.

The server currently has no windows open Uptime reveals 0.35, 0.47 and 0.25 Finger reveals only two users logged in (me from ssh on another box and me on console) Normally at this stage, I'd do a netstat -a and or a ps aux to find out what's using the CPU and network but having done both, I see a lot of stuff I can't interpret (for example CPU processes enclosed in square brackets) and besides which, as I'm in gnome on the desktop, I'd assume these are all required processes.

[Hampshire] Box on last legs
Hi all My dad (an electronics engineer of 40 years experience) once told me intermittent faults are a swine to fix - and never truer words were spoken. Could you all please take a look at my logic before I condemn certain parts of this failing box to the bin? 2008 vintage 64-bit 4Gig RAM machine running Ubuntu 12 fine for the past month - 28 days uptime as my media server and no problems at all. Today I switched the kvm box controlling it to control another machine (no disconnection, just a flick of a switch) and the box powered down! For some reason whenever the bad box powers down, it needs to be physically unplugged from the mains before it will come back up - this particularly baffles me. Brassed off with this, I started to look into what causes random shutdowns (it's not the first time it's done this but as I say it's been fine for 28 days). I left it running for 20 minutes in BIOS to check the CPU temp was fine - and it was at 44 degrees C max. Rebooted to see what dmesg might say but - post BIOS but before boot - it shut itself down. And at that point my anglo saxon became taboo for the good folks on this list! I'm now stumped and, as the machine is 2008 vintage (though good for its time) it might be time to upgrade - but I'm wondering which bits I can salvage. I'm thinking the following are ok to reuse: case, optical drive, hdd whereas any of the mobo, RAM and certainly PSU could well be the trouble and it's almost impossible to test which. Can anyone offer another diagnosis / treatment for these symptoms? I might be inclined to buy a new PSU and see what happens swapping that before any more major surgery but is there really anything I've missed as regards seemingly random shutdowns? Incidentally when I say shutdown - I'm talking immediate power down - not the OS executing a halt command.

[Hampshire] 8TB Cloud
Hi all I'm trying to build a PC which has 8TB of storage - to be my media server. For the moment, I'm deliberately ignoring devices like microservers or Drobos - mostly on cost and the fact I have several towers with enough space to take 4*2TB drives. I've not built a PC for ages so I have a few questions: 1) Is SATA still the bus of choice? According to Novatech, there is now Serial attached SCSI. I don't think any of my mobos have this bus, and indeed it seems the drives sizes here are a lot smaller than I need - but is there anything pushing this over SATA? 2) Presumably I need a stronger power supply. If there are 4 hdds and 1 DVD drive - what sort of wattage should I be looking at? 3) If, expense notwithstanding for the moment, I did this as 4*2TB external USB hard drives, I've had trouble sharing these with Ubuntu before now. For some reason they're mounted under /media under a strange (and seemingly random) string of characters (which change every time the server is restarted) such that permanent shortcuts from other devices on the network wouldn't work and would need to be re-established each time I connect. Has anyone worked around this? Any constructive suggestions very welcome.

[Hampshire] gnome Applications menu keyboard shortcut
Hi all After several unsuccessful google searches, I have to ask. Alt+F1 doesn't bring up the applications menu in gnome any more - does anyone know how to reinstate it? I'm using Ubuntu precise so it's presumably gnome 3 (quiet bee in my bonnet that I've never really known how to tell which version of nautilus, gnome, etc etc I'm using) and did the upgrade a while back. The reason (as I recall) for alt+f1 not working is that compiz fusion has captured the alt key but I can't find a page or a post anywhere that fixes it. Sadly I can't find the page with the winning formula at the moment. Even removing compiz fusion hasn't fixed it. All I want to do is bring the applications menu up. If it's a different shortcut now then fine - I'm not wedded to alt+f1 but if it's a super key then I'm stuffed because my keyboard is 1994 vintage and has none of these. So if that's the case, a workaround for that would be useful too. As an aside, I think I must be entering my grumpy old man phase of tech. I'm fed up with the Microsoft Ribbon, the seemingly never ending changes to user interfaces that actually seem to introduce making things harder to do than concentrate on functionality. grumble grumble don't-get-me-started-on-the-latest-sky-hd-box-upgrade grumble grumble.

[Hampshire] An interesting rsync problem
Hi all This may or may not be of interest to rsync fans (and by the way many many thanks for all of your help the other week). Here's the situation.. One of the files I want to backup is an rsync container. As it's a container, its' file size is always 100Gb exactly and (I've just checked) that its' date stamp remains the date I physically moved it from its' previous home to my new server - despite the fact the contents have changed daily since then. So if (as according to rsync's man page) the algorithm checks for a change in file size or date stamp - it will determine this file doesn't need attention. Anybody know of a way to bypass this and force it to copy the file every time? It's no great strife of course to just zap the file every time I do the backup (or even add a simple cp to the backup script that runs the job) but just wondered if anyone's come across this before and found a more elegant workaround.

[Hampshire] Samba tutorial
Hi all Does anyone know of a particularly readable tutorial on Samba? When I've setup samba shares so Windows machines can see Linux boxes before, it's been pretty much a surprise that they've worked. Ditto getting Linux machines to be able to write to NAS boxes as non-root users. My current problem is trying to make a directory on an external USB HDD on an Ubuntu host available as r/w to a Windows host. I can make said host see and read from a folder under /home/whoever but (even soft linking /home/whoever/test to /media/ExternalHDDname is failing. To make matters worse, the gnome users and groups admin thing has failed completely i.e. click Add and it doesn't add a user, nor can I delete one -all in all a bit of a meltdown really! There are of course thousands of pages about samba and I'm sure O'Reilly would be its' usual encyclopaedic - but all I want is to understand how users and groups work in Samba so I can set appropriate permissions - anyone know of a good resource?

[Hampshire] Crash course mobile broadband
Hi all Given my eyesight, Ive never had to worry too much about smartphones or mobile broadband but a monster train journey shortly is about to change all of that so I need to know (by Tuesday if poss!) what kit I need. I have about 7 hours on a train on Tueday and need web access while doing so. Thus far, I only have access to a Toshiba satellite laptop running Ubuntu. In theory, I think all I need is [1] a usb dongle from argos or somewhere similar and Im away. But I have several questions: 1) Will a high street dongle work with Linux? 2) If so I dont want to do any sort of contract I want to just pay £20 for some sort of 1Gb limit and chuck it away post use do these things still exist? 3) How good are these things really? Say I wanted to catch up on something on iplayer in between faffing about with spread sheets for work is this really feasible on a fast moving train? 4) Said laptop is 2009 vintage and Ive been thinking of getting a new one is it worthwhile buying a 3G laptop?

[Hampshire] [Very OT] Cable TV and IPTV
Hi all In essence, this is a yes / no question... Can I watch live TV via BT Vision if I have no TV signal? From the research I've done, the answer is no. With no Freeview signal, the BT Vision box is left with only on demand services. Whether this extends to the live TV that is watchable via BBC iplayer I don't know but presumably it means catch up services. Essentially our new house is fine when the weather's good - both Freeview and satellite are fine. But when the weather's bad - both signals are either down or intermittent. In the old days - no problem - I'd switch to ITV via cable TV. But now we're out of a cabled area, the only way I could see to watch the Olympics yesterday during a thunderstorm was via the web. Fine via PC but so far as I can tell - not all channels provide live streams without the faff of logging in etc. So I guess the other question is - is there an alternative to a Virginmedia box if you're not in a VM area?

[Hampshire] [OT] Citrix
Hi all For my own education please, I need someone to explain a potentially far reaching decision made by our IT people at work At present, we're still stuck on Windows XP and MS Office 2003. The system works quite well but is beginning to struggle with the big datasets I have to handle. So they've just bought Windows 7 PCs and the spec is pretty good (Intel i5, 8Gb RAM). The most bizarre thing is myself and my colleague have been asked to test them as power users and the implementation they've deployed is via a Citrix container - whatever that is. I freely admit to knowing next to nothing about Citrix but I thought this was something akin to remotely controlling another PC - except that the PC you're remotely controlling was virtual - is this wrong? If I'm right, surely it means that all this wonderful Intel i5 power is effectively being used as a terminal and the speed we'll have is the speed of the machine we're controlling. The reason I ask is there's some specialist software for the visually impaired that I use which is never going to work over Citrix because it was never designed to do so. I have a nasty feeling that they're going to turn around and say my software can't be used - and that could have very far reaching consequences for me. So what is Citrix and can anyone see why they may have set things up in this way?

[Hampshire] [OT] ISP level of tech support
Hi all Slightly ot but something we all have to do at some point... I ask in all honesty - could / should any ISP have been able to do more for me in my situation? Tonight I contacted Zen because (having only had my connection activated a couple of days ago) I returned home to find no connection. Restarting the router fixed it but, just to be sure, I checked the logs thinking it might be to do with training mode. As it's a new router (supplied by Zen) I'm not that familiar with all of its' log speak. I rang tech support to find out why it had dropped the connection. I was told that: a) they couldn't tell me why the connection had dropped b) the logs had contained entries around the time of the drop for Firewall rules modified which worried me slightly. I would have thought that only I, as admin, could modify my firewall rules. When I asked him about this he said Zen didn't support the router (even though they supplied it!) and he couldn't explain what rules were modified or why. It's probably coincidental that he sounded like a right lazy so and so but to be honest, I expect better from Zen. I'm not that much in a huff because all is well that ends well - I have a connection - but I'm more surprised than anything. Zen are usually brilliant for customer and tech support - so don't want to see standards slipping - but similarly I don't want to hold them up to too exacting a standard.

[Hampshire] rsync 101
Hi all I need a bit of help with rsync (well grsync actually but I assume grsync is just an interface to rsync) please... What I've used it for in the past is to mirror two drives - and it works fine. However I've noticed the following and I need a workaround. Let A be the master and B be the backup. If A contains: /foo/bar/fred Say I've backed up A to be before such that B now also contains /foo/bar/fred Now let's suppose that I make a change to A so that it is now /foo/bar/1987/fred (and fred is still the same file). Running grsync in the usual way means I end up with /foo/bar/1987/fred (which is correct) but I also end up with /foo/bar/fred (which is now a duplicate - and can be deleted) What I want grsync to do is ensure B is a direct copy of A. I'd prefer not to do this via taking an image (because A and B are retail USB 2TB drives and have some form of windows utility (which comes back after formatting no matter what fs I choose) on them and the last thing I need is to render them unusable). I suspect it's just a switch I need to set but I can't find it immediately - so any help very well received.

[Hampshire] Recommendation please - Big NAS
Hi all I'm looking for a NAS device / media server - need a recommendation please. 1) Needs to be able to store 4TB+ of data so presumably need at least 2 drive bays. 2) Needs to be on 24/7 I was thinking (and this list has previously raved about) a HP microserver. However this gives me a dilemma. I have a PC I could resurrect at the cost of the drives (which I'd need for the microserver anyway) and the cost of a big PSU (big enough to run several hard drives in one box). Said cost would probably come out just under the £230 for a microserver. All of my previous NAS devices (Bufallo Linkstation, Netgear SLU, Netgear ReadyNAS) have all been devoted NAS units so this is the first time I'd ever be buying a proper server if I bought the HP thing. So I guess my question is - why not build a machine myself instead of the microserver? Quietness isn't much of an issue because it'll be in a room separate to the TV. Are there any other considerations here?

[Hampshire] Yet more on DVD+RW ripping
Hi all [OK - if you're sick of the sight of emails from me about ripping DVDs - I don't blame you and you're probably best not reading further] For the hardy breed that have gone past that disclaimer please bear with me. I have these 200+ DVD+RWs recorded since 2004 and the following phenomena have been observed. 1) Very few (10-20%) play ok in either a DVD player, a DVD drive on a PC, a console or (most irritatingly) the darn machine that recorded them. 2) In most cases, if playing though the DVD recorder that recorded them - it gets to around 40-50 minutes in and just about freezes. Identical, you might think to the disk being dirty - but they have been well looked after and are pristine. 3) Ripping software has (because the content has camera angle moving) proved pretty bad. All sorts of results from delayed audio, to wavy vertical lines when the camera angle moves and nothing has fixed this. I've tried Handbrake, Alcohol52%, DVD Decrypter, Digiarty and just about everything else suggested. 4) This is what's really odd... I have just created an iso from a DVD+RW showing the behaviour in 2) above. Mounting this and playing a DVD it seems to work fine! Now here's the dilemma as I need to get a working strategy to get rid of 200 disks as I hope to move house shortly... a) Why is making an iso working when I can neither rip nor play these things properly? b) If I simply make iso images of these disks, this is equivalent to making a copy of the disk itself is it not? As such, if I happen to find a workable ripping solution at some stage later - all I have to do is mount the iso do I not? In other words, I'm not losing anything at all by creating an iso - that is right isn't it? The reason b) is bothering me so much is that my current method of watching these ripped videos and dvds is via a netgear neotv which is a little box under the tv that can understand most file formats. I very much doubt if it will understand isos. To be honest, I don't care if it doesn't understand isos if one day I can transform these isos I will be creating into avis, mpgs or whatever but it's proved impossible so far to go from dvd+rw to avi. Perhaps iso to avi at some later stage might be easier - but the key is I don't want to lose anything in the process of going from dvd+rw to iso. Sorry this has been a bit rambling but I've spent a lot of time over the last few years building up this library - I don't want to lose the physical media in the move and I certainly don't want to lose the content thanks to an oversight. After all this - my question boils down to - do I lose anything if I create an iso of a dvd+rw image?

[Hampshire] More on DVD Ripping
Hi all I think I'm making some progress but need the advice of those who know more. To recap - it's around 200 home made (full DVD+RW) disks I'm trying to rip to PC. I was getting all sorts of problems with the finished output from handbrake being weird - snowstorms, wavy, blocky etc. I now seem to have a working method but need to check one thing... I have a program which is seemingly copying the vob files off the disk and getting them onto my hd. I then use another to encode those copied vobs into avi. Both are Windows programs I'm afraid but I did do extensive testing using Handbrake for Linux. The resulting avi is, in the tests I've done, fine. My question is - is the copied vob file all that I need in terms of content? I notice several other smaller files on the DVD which I'm not copying but I'm assuming these are the placeholders and menus etc such that the actual content is the vob file - is this right?

Re: [Hampshire] DVD Ripping
Thanks everyone for your suggestions. I have actually been using handbrake too but having problems with that along the lines of the quality of the ripped product. The majority of the disks I have to rip are sport - and while the majority of them were not brilliant quality in the first place (recorded at 4 hours per disk to keep costs down), the finished product from Handbrake was rubbish despite a lot of faffing with things like decomb, deinterlace etc etc. However this brings me to 2 further questions: 1) If I accept Handbrake as the tool of choice, then what combination of settings simply gets me (no matter how long it takes or the size of file created) an identical copy of the disk? 2) I think part of the problem here is that the disks I have are home made - not commercial - are there any special known issues ripping home recorded DVDs? They play ok in just about everything (Blu Ray, XBox etc) but handbrake is struggling to copy them.

[Hampshire] DVD Ripping
Hi all I think I asked something similar a few months back but please bear with me - as ever this is driving me mad... I want a simple program to turn a DVD into a video file - purely for personal use - need the space in the living room - I'm not doing anything knowingly nefarious here. For the moment, let's not concentrate on which format and therefore which codec. For what should be not far short of a simple job - I'm coming up against all sorts of weirdness trying to do it either free or with Linux or both. I've tried k3b, which just hangs I've tried k9copy to produce an iso - which works but not sure what good that actually is - save for burning the iso back to optical media again as backup. I've tried dvd:rip which seems to work - until you play the avi back and you get the equivalent of an analogue TV picture which hasn't been quite tuned in well i.e. diagonal lines and crackled unintelligible sound. I must be missing something - and I'm getting to the stage where I'd happily pay for something that works. With umpteen DVDs and a smaller living room, need something quick (in every sense). Surely there must be a simple program out there to rip DVDs easily. Any ideas anyone?

[Hampshire] PSPP Libraries
Hi all I have asked a similar question before but please bear with me - I'm sort of making progress but still not quite there... I'm trying to compile a tarball from source. The problem I'm having is ./configure is crashing saying I need cairo1.5 or later and pango1.5 or later. So I headed for synaptic, installed them and reran configure. Same error. I've never been too hot on this facet of Linux - do I need to do anything else having installed the package libcairo to register it such that ./configure can see it? I suspect I'm missing a fundamental step here but I can't think what it is. The background to this is I'm trying to run a stats package called pspp. The problem is that installing it via synaptic gives me a very old version with very little functionality. The developers are doing this deliberately and the latest version is available as tarball binary and tarball source. The binary version doesn't seem to work (in a much as I get executable files which don't run) but according to the mailing list - much more emphasis is on building from source.

They seem bemused when I say I hate touchscreens (which I do for phones - ipad is different!) and I don't want the net on the move. All I basically want is a phone which can do huge fonts and has buttons - and that's it. I scarcely even text nowadays but that's useful for (for instance) contacts from the kids' school.

[Hampshire] Dying HDDs
Hi all As you may remember from my post last week, my Ubuntu machine's HD died. Despite a brand new HDD I'm having intermittent problems ranging from install failing to complete with another HDD error to the BIOS not detecting the drive at all. I have literally just tried a new SATA data cable and all (so far touch wood!) seems well. The thing is - if the problem persists - what part should I look at replacing next? The PSU? The mobo? Could this be some sort of mains AC problem and would a new surge protector be more the order of the day? I should add I have several other boxes on the same ring main that appear to be working fine. Are these new (yada yada I know I'm not exactly Mr Current Affairs) SATA data cables any better or worse for bad connections than other types of BUS e.g. usb or even pata ide?

[Hampshire] Dud FS?
Hi all Funnily enough, I was reading about the prolonged hard drive price hike yesterday and hey presto, looks like I have my own drive failure today. Can anyone suggest if the following is terminal? I got the Ubuntu Target filesystem doesn't have /sbin/init and (not surprisingly) no GUI. Thinking a damaged fs, I got myself a Slax livecd and booted into a terminal and then gave it a bit of: e2fsck /dev/sda1 -f -y -v only to be confronted with: root@slax:~# e2fsck /dev/sda1 -f -y -v e2fsck 1.41.3 (12-Oct-2008) /dev/sda1: recovering journal /dev/sda1: Attempt to read block from filesystem resulted in short read while reading block 9337460 JBD: Failed to read block at offset 30802 e2fsck: Input/output error while recovering ext3 journal of /dev/sda1 root@slax:~# Looks pretty terminal to me but I've never been too hot on low level stuff like this. My question is: 1) Is that it for the drive i.e. chuck it away (responsibly of course) or 2) Is that it for the fs but the drive can be reused (i.e. a reinstall)? Either way - anyone know how I recover such data as there is on it? There wasn't much.

[Hampshire] BT Infinity - was RE: VDSL equipment
-Original Message- From: hampshire-boun...@mailman.lug.org.uk [mailto:hampshire- boun...@mailman.lug.org.uk] On Behalf Of Mike Austin Sent: 02 January 2012 13:48 To: hampshire@mailman.lug.org.uk Subject: Re: [Hampshire] VDSL equipment I have experience of both the Virgin Media cable broadband and BT Infinity, which my lady has at her home. It is worth explaining the difference to help understand their use. In both cases the fibre optic cable is fed to a box in the street somewhere near your home. With Virgin, the broadband signal is fed to the house via a coaxial cable with separate phone line. In my case the coaxial cable also supplies my television signal. In the case of the BT Infinity connection, a two core copper cable is fed to the house and carries your telephone and broadband data. The standard installation involves replacing your primary telephone socket at the first point of entry of the BT line into your home. The new face socket has a VDSL outlet to the modem, and a standard telephone outlet. BT provided a Homehub router wired to the modem. Any telephone extensions are fed from the new box and do not require a separate filter. You are then faced with a choice of using wireless or powerline plugs if your desktop is elsewhere. Incidentally, some of the latest powerline plugs include wireless capability. Since I run three WAPs in my own home, on different channels with different SSIDs, they could have been useful. In reality, you can move the new telephone socket to a more convenient point in your home if you have suitable wiring already installed, as most homes should. The installation engineer may baulk at this as they prefer not to use your existing wiring. If anyone wants me to explain the procedure, I will do a follow up. Mike Thanks for this Mike - very clear. On a slightly different note, BT has clearly badged this as BT Infinity because they want to sell the set top box which, as far as I can tell, what they're actually doing is installing a VDSL connection and proprietary hardware to stream content over said connection. Is there a set top box out there that basically does the job of a TiVO or BT homehub/infinitiy/whateveritscalled but is not tied to a particular ISP? I know, for instance, that PS3 and Apple TV can connect to lovefilm, blinkbox, iplayer etc but you need a separate account for each service - which is a huge faff. The BT set top box, as far as I know: a) requires BT total broadband - which I don't want because I hate BT as an ISP b) is basically a freeview box which streams non-freeview stuff over the VDSL connection. So as I will have a VDSL connection and I already have a freeview box, to use BT as an ISP for the purposes of Sky Sports is a waste of time. I just wondered if there was a box that was ISP independent which would do this for me. I guess there's always SkyPlayer!

[Hampshire] VDSL equipment
Hi all I think I'm going to take the plunge with Zen's Fibre Active package. I've done a lot of reading but I can't find anywhere answers to my key questions - grateful if anyone can fill in the gaps: 1) Starting at the socket, the Openreach engineer is apparently going to swap my faceplate. So what sockets will there be on the new faceplate? I've seen images but can't tell if one's now ethernet and the other a standard phone jack or if they're two phone jacks (presumably one voice, one data?) 2) The engineer is going to install (I assume this means plug in and go no further) a VDSL modem. Let's assume for the moment (see below) I don't buy any new equipment. Can I just connect this new VDSL modem to a PC (and if so are we talking ethernet or USB?) and have it connect via DHCP? This is exactly what happened when I got my first cablemodem before I added a router. The reason I ask this is that, with no router in the mix, there would have to be a seriously configured software firewall on the PC wouldn't there? To connect to the net without NAT is quite risky isn't it? Certainly it used to be! 3) Zen want to sell me an appropriate router (which is understandable) but I do (somewhere!) have my old cable router i.e. the one I used to attach to my Virgin cable modem at my old house - I'm assuming I could use this couldn't I? 4) My Sky box needs the phone line and at present it's connected to an extension of this line via a standard ADSL microfilter - any issues here? 5) A ten fold speed increase for just over a fiver more than I'm currently paying per month (and Zen have been excellent IMHO) sounds a good deal - does anyone have any reservations about VDSL?

[Hampshire] Big storage
Hi all I'm wondering if I'm missing a trick here - perhaps someone can help... I have a pretty big (already 2TB and likely to be nearer 4TB+ by the time I've finished) media library (all mpgs) - how should I be making this available over my network?

Googling reveals something called a Belkin network usb hub but the reviews are awful. I know I could contemplate the cloud here to keep this lot for me - but this is: a) going to cost a lot and b) getting 4TB onto the cloud at an upstream bandwidth still measured in kbits rather than mbits would be beyond painful I can't be the only one with a huge DVD and video library but the majority of drives I've seen on the high street are 2-3TB.

[Hampshire] NAS only write as root
Hi all I know this is an old chetnut but I never did get it sorted when I asked last... I'm having trouble accessing my nas devices through Ubuntu. I have 3 devices. I tend to mount them as follows: mount -t smbfs //ip/sharename /mnt/share -o user=rob This seems to work for all 3 but has two oddities: 1) I can only write to them as root 2) In one case, the share comes up as 3% used through df -h, the other time it comes up as 100% used. Should I be looking at: a) the mount syntax to mount it read write b) the umask c) the permissions on /mnt/share One of the 3 nas devices (a Netgear ReadyNAS duo) doesn't have any users. Even more weirdly, if I copy a 27Mb file to it - no problem. But if I copy a 450Mb file to it, it seems to work ok but when I ls -l I get file size is 0. All in all there's a lot wrong here and I'm a bit lost as to where to start so any helpful suggestions would be very welcome.

[Hampshire] Ubuntu Ocelot - pointer disappears when over icon
Hi all I'll describe this as best I can - hoping someone knows a workaround - easier than googling. I've just upgraded to Ubuntu 11.10 (Ocelot somethingorother). The default Unity window manager I don't like - gave it half an hour and went back to gnome classic but there's a rather irritating change that I'm hoping I can undo. Essentially in the new system settings window, the pointer disappears when you're over an icon. Is there any way around this? Personally I find it disconcerting enough losing the pointer so to have it disappear just when I'm not 100% sure I'm over an icon is a real pain. This is as true as gnome classic under 11.10 as it is under unity under 11.10. I've hunted around the obvious places like mouse settings and no joy. I'm hoping this can be fixed because (and it's a personal thing as I'm very short sighted) I am finding it much harder to use.

Re: [Hampshire] Help please - Rusty on building a PC
Thanks to all who replied. On the extra connectors, thankfully my graphics card doesn't need one - there are no connections on it for power. On the ps2 situation, as I say the mobo only has one ps2 so what I've done is buy a ps2 splitter - the sort of thing we used to use for laptops i.e. I think it will allow kbd and mouse into the same ps2 port. It'll be a real shame when usb takes over from ps2 completely as I strongly suspect (it's almost certain) that this will be the end of my 18 year old Cherry Click keyboard. Goodness only knows how many keystrokes in all that time - including my dissertation at 50k words! Out of interest while on the subject, can anyone recommend a good keyboard vendor?

[Hampshire] Help please - Rusty on building a PC
Hi all My mean machine arrived today (Intel i7 2600, 8Gb DDR3) barebones and I need to build it. The thing is, I'm seeing a huge bundle of unfamiliar connectors - can anyone help? My main concern is keyboard and mouse - there's only one ps2 on the back of the mobo. I can think of 2 solutions: 1) Buy a ps2 female to usb male and use my ps2 mouse with that. [In fact it'll be connected to my kvm] The only thing I'm worried about here is whether the mouse will be correctly detected. 2) As I'm chucking out the Mac mini I bought 5 years ago and basically never used, it so happens that I have an existing 2 ps2 female to 1 usb male adapter. Is this any better than 1) above. Now onto the really confusing stuff. I'm used to power supplies with: * Mobo power * Fan power (which connects to mobo) * a ton of standard 4 pin power plugs. In this latest board, I have 1 mobo power, seemingly 2 fan connections and no standard power plugs, they all seem to be the new SATA variety. Luckily enough, the hdd and dvd I have are both sata, but there seem some other connectors too (I haven't the technology to take a photo at the moment) so could someone tell me what they're likely to be - they look like terminal blocks to me!! Sorry for these basic questions - it's been well over 18 months since I built my last machine.

[Hampshire] Analytics packages
Hi all Does anyone know a good, user friendly statistics / analytics package for Linux? The trick is - it needs to be able to handle an absolutely massive dataset - 13m rows. For Uni, I have a dataset with no fewer than 13m records and I need to run a regression on it. In fact I probably need to run about a thousand regressions comparing results later. In theory, something like Libre could handle the individual regressions once I've split the txt file up but I don't want to get into faffing around with awk, sed, cat, head etc etc (takes ages, creates massive files and besides which the file needs splitting according to a rule which uses a field within it that at present I can't guarantee it's sorted on). I can't afford the frankly ludicrous prices charged for SAS and SPSS. I just wondered if any of you knew if there was something really good that people are using and I've missed. I've tried: R [1] - powerful but very clunky and a dreadful GUI PSPP [2] - still a work in progress and truly awfully formatted output. It'll get there one day but it's a mile off at the moment. DAP - won't compile for me and I don't have time to investigate. gretl [3] - seemingly for economists who seldom have to handle such big datasets.

[Hampshire] Lucid - startup scripts
Hi all Can anyone tell me where to put a script which I need to run once gnome has initialised? Essentially my problem is as follows: Not sure if they've fixed it yet but lucid had a problem with wheel mice where when browsing in Firefox (not sure if other browsers were affected) if you scrolled up with your wheel, Firefox would interpret this as a Back operation so when you were trying to scroll back up your webpage you'd be sent rapidly back through your browsing history. The good news is: sudo rmmod psmouse sudo modprobe psmouse rate=100 proto=imps fixes this. So I need this run at some point during the boot process. I'm so old that my first thoughts were .profile but this would require the su password which is irritating and surely /etc/init.d/somewhere would execute before gnome had initialised.

[Hampshire] Data Destruction

I know data can be recovered even if you wipe the partition etc so here's my plan - any ideas how robust this is?? Essentially without a safe data shredding program, I'm going to use truecrypt to create an encrypted partition over whatever data was there beforehand. AFAIK this must overwrite what was there with a blank drive (not just a new partition table) which could only be accessed if they guessed my truecrypt encrypted password. So at best, someone could only ever get back to the blank encrypted drive - not the ntfs partition that was there before I formatted it with truecrypt.

Desmond showed me PiTiVi and that's what I now use, doing pretty much the same as you want to do. Here's an example of result for web, from a stills camera: http://steamtube.ning.com/video/walschaerts-valvegear-mhr-12 (best at 480) Both my computers are 2GB too. Happy to help (off list) if you need. Tony Wood (from Linux PC) Thanks Tony. Just gave it a try and it looks ideal.

[Hampshire] [OT] Thermaltake Tsunami Tower Case
Hi all Anybody ever bought a Thermaltake Tsunami case? If so, have you had any problems with it? The reason I ask is the machine I have in this case has today developed a random power off feature - great ;-[ Curiously enough, this case has previously contained a different machine which also suffered from overheating. With the first machine, I got a warning sound, today's machine just powers off after 5 minutes or during the video editing I was doing - see previous thread. As ever, it's a case of not wanting to spend good money after bad. All fans seem to be working and I've never had a problem in any case I've built a PC in before so I'm just wondering if this case is flawed somehow. Nothing crops up on Google but it is a bit old now so that's not surprising. Any ideas anyone?

Nothing crops up on Google but it is a bit old now so that's not surprising. Any ideas anyone? Is the PSU AOK? Is the CPU paste gone? Is the heatsink well seated? Is the heatsink clean - I stick a pencil into the fan and blow the heatsick clean with an air line. Even then the muck eventually builds up in the bottom of the h/sink and it ends up being replaced at least once in a machines life. Have you checked for blown caps? When the machine dies, unplug and open the case - look and smell - if it is a blown cap in the PSU or mobo you *will* be able to smell it. Is there anything in the logs? Do you have anything running monitoring the CPU temp etc? Thanks Jacqui. I've opened it up and found the culprit immediately. Somehow the floppy drive caddy was pushed up against the CPU fan. Whether it was running I don't know (I'd assume it would power down well before 5 mins if the CPU fan hadn't spun at all) but it's running fine now.

Re: [Hampshire] natty - 2 weird things
-Original Message- From: hampshire-boun...@mailman.lug.org.uk [mailto:hampshire- boun...@mailman.lug.org.uk] On Behalf Of Ian Grody Sent: 12 September 2011 02:06 To: Hampshire LUG Discussion List Subject: Re: [Hampshire] natty - 2 weird things [snip] Cheers Rob Hope this helps :-) Thanks Ian - that's certainly fixed the networking side of things but 2 problems still remain (one I forgot to mention yesterday). I know how bizarre this will sound but I can now not move my pointer higher than about 80% of the screen (if the bottom of the screen is 0). I move the mouse and it stops about 80% of the way up, and picking up the mouse and starting again doesn't work. This makes configuring anything with the mouse a bit tricky - luckily I'm quite happy with keyboard shortcuts but even so... - anybody know why the pointer would stop at about 80%. Obviously I've tried to come out of VirtualBox and the pointer is fine within Windows. As for the theme of the top bar changing, I'm currently fiddling with compiz. I did try and simply uninstall compiz with synaptic but that didn't do the trick.

[Hampshire] Slightly OT - Firewall Server
Hi all A simple question: What is a firewall server? I've not heard of this term before. Is it: a) A pretty low spec server that's not got much processing power beyond that required to run ipcop or something similar? b) Something else I anticipate it will have more than one NIC but if I was looking for a really low spec server (or a few of them of identical physical dimensions) as I am at the moment, what's to stop me buying [1]?
