What's the easiest way to copy bits of several PDFs onto one page?
by Chris Green 06 Mar '19

06 Mar '19

I have a multilingual manual for a new tractor mounted mower. It's almost unreadable because the 'multilingual' is done by having five columns of text (one of each language) down the pages. So I thought it would be easy to scan just the English columns and paste them together, five columns to a page, to make an English only version of the manual. It's not at all easy! There are very few programs that will 'merge' PDF pages and those that do seem to assume one is just trying to pack two or four complete PDF pages onto one sheet to save paper. So can anyone suggest how I can do this? I can very easily scan the English bits as required, what I need is a handy tool for putting a number of scanned images onto a page. I was trying to do this using PDF but it may well be that other file types would be easier, I can scan to JPG, TIFF, PNM, etc. easily enough. -- Chris Green

Booting from a dvd
by Bev Nicolson 22 Feb '19

22 Feb '19

So I thought I get going on installing Cinnamon Mint in this laptop. Plugged it in, got the dvd in but it just booted to Windows 7 instead. It knew the dvd was there and what was on it but that was as far as it went. How to I investigate why it's doing this and/or how do I get it to install Mint? Ta. Bev.

Re: [ALUG] main Digest, Vol 164, Issue 10
by Al 22 Feb '19

22 Feb '19

I wouldn't try to mix EFI and BIOS in a dual boot system. Did it, with Mint, and without being able to recall the detail, it was a mess, and I recovered by reinstalling Windows and then installing Mint in EFI mode. Fortunately the Windows registration code had been stored someplace mysterious and invisible, so the reinstallation just picked it up fine, and then Mint went in just fine after ooting from the DVD in EFI mode and then doing the install after that, and everything was fine. I have a vague recollection of having to create the EFI partitions again manually. Or maybe that was some other misadventure with EFI. The other experience I have in this matter is, never, never update the BIOS. I did, having foolishly listened to advice that it was necessary, which it was not, and the main board was hosed, and the only way to recover was finding a shop somewhere in the Himalayas north of Watford who extracted the chip and reinstalled it. There is a lot to be said for old main boards that just do BIOS!

Setting up laptop
by Bev Nicolson 20 Feb '19

20 Feb '19

So, I have a new to me laptop. How do I sensibly and safely transfer passwords, bookmarks etc onto it? I've tried to back them up before now (Firefox's 'import bookmarks from html' option) but I'm not wholly confident about that method. Step by step please. And is my assumption that because it has more memory and is newer than my current pc that a 64-bit OS (Cinnamon Mint if you’re interested) reasonable? Bev P.S. For Steve: sadly I think the scanner has gone on to the choir invisible...

embedded iframes in Firefox etc
by Phil Thane 16 Feb '19

16 Feb '19

Hi, > Following my questions about embedding a GPS tracker into my website I've followed Chris Dawkins (ALUG) suggestion and installed GPS Tracker 2 on my phone and created an account on Greenalp. This works OK (I had to wait for Greenalp to unlock my frame for embedding) on Chromium but not on Firefox (my usual browser) or Vivaldi. In both cases I get a message to the effect that map has loaded, please refresh the page. A normal page refresh doesn't make any difference to the frame which shows the Greenalp home page not my map. Is there some cunning code I can add to the iframe code to force a reload of the frame contents? I've tried searching online but not as yet found anything useful. -- Phil

realtime GSM mapping
by Phil Thane 08 Feb '19

08 Feb '19

Hello all, As the N Wales and Wrexham recipients of this will know, I'm not a developer, the Anglian recipients probably don't know me at all but I moved here a couple of years ago. Over the last 15 years I've written a lot about Linux and FOSS for various magazines and websites, but I'm no expert, so bear with me. Now I'm mostly retired I have a river/canal cruiser. Last year I did a single-handed trip of about 10 days in each direction to a boat show. So that my family could keep track I enabled 'find my phone' on my mobile and gave them the login details. OK as far as it goes but not ideal obvs. I also blogged each day and then wrote it all up for a boat magazine. This year I plan a longer trip - to the Llangollen International Eisteddfod - about 3 weeks each way. I've sorted out WIFi and a laptop charger on the boat so I can blog better, now I'd like to improve the mapping. The ideal would be a map I can embed in a WP page on my website, that updates every few minutes as I travel. GPS from either my phone, or if really necessary a dedicated GPS device. Does anyone know if such is already possible using OSM + plugins etc? I've had a quick look online but most advice refers to Google maps. Most of the rest gets very technical very quickly. Goes over my head. Plan B, is there a dev out there looking for a project? Unpaid and 'free' naturally! Would it feasible to create something like FlightRadar' that displayed boat positions on inland waterways? There is already marinetraffic.com for shipping, but that's way too big. I'm thinking of something boat owners could subscribe to that was available online and capable of being embedded in a webpage. -- Phil

Running multiple commands "securely" with one password
by Mark Rogers 25 Jan '19

25 Jan '19

I need to write a script that runs several tasks against a remote server via SSH & rsync. To be keep it simple, imagine just an rsync followed by a command via SSH. I don't want this to be passwordless - I want the script to require the remote password before it runs. But I don't want to have to enter it again until the script ends. Is there a good way to do this? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

OT Old email address
by Bev Nicolson 25 Jan '19

25 Jan '19

I've got an old (redundant) email address and would like to keep all the emails associated with it (for now at any rate.) They are all stored on my computer but I wondered if there was another way of saving them to view on Thunderbird without the email client trying to log in to the server every time I want to read them? Googling does not bring any useful info thus far. Bev.

OT: Domain registration/DNS hosts
by Mark Rogers 29 Nov '18

29 Nov '18

(OT but I think there's likely to be both knowledge and interest here. Correct me otherwise!) Most of my domains for historical reasons are with 123-Reg and I've been looking to move somewhere more reliable for years. 123-Reg has the advantage for me that I know it well but it's time I moved if that's the only thing keeping me there. All I *need* is to register/renew domains and handle their DNS. Ideally I would also *want* to have email/web forwarding. However I will never need them to provide email/web hosting. Most of the domains are .uk but with some exceptions. Who do others use and why? Who should I avoid?

Hard disk drive partitions and memory
by Bev Nicolson 18 Nov '18

18 Nov '18

1) Noticing that this PC gets glacially slow occasionally (it probably means get a new one and soon but bear with me for the moment) I had a look at the hard disk. 77 GB is 84.4% full. I have two partitions though. One 'extended partition', the other a swap partition. Both 3.1 GB. Could I unmount the first (extended partition) safely? 2) What is it full of and how could I clear stuff out, again, safely? Bev. (braced for the worst.)

Unreliable USB3
by Mark Rogers 13 Nov '18

13 Nov '18

I frequently find USB3 unreliable, on more than one PC (but not all). Typical usage will be to take images of SD cards via a card reader or to access data from a hard disk via USB->SATA. Generally, it'll connect and be visible for a short while before erroring. My current PC lists its controller as: Intel Corporation 100 Series/C230 Series Chipset Family USB 3.0 xHCI Controller (rev 31) How do I go about diagnosing this? Is it likely to be the driver, the hardware, or the external devices? syslog from most recent failure follows. On this occasion, I was connecting through an unpowered USB3 hub, but the problems are pretty typical regardless.

Is there a way for an ssh connection to allow the server to send a file to the client?
by Chris Green 02 Nov '18

02 Nov '18

I am looking for a way that will allow my ssh 'server' machine (desktop running xubuntu 18.04 at home) to send a file back to the client machine (laptop running xubuntu 18.04 which may be anywhere including behind a firewall etc. and behind NAT). I need the server machine to be able to do this from a script running on the server at some indeterminate time after the ssh connection has been made. The only remotely possible way I can think of to do this is to run something via the 'LocalCommand' option in the client ssh configuration. However, at the moment, that's about as far as I can get. I can't think of a way of actually doing it at the moment. The best I can come up with is to have a script (run as a LocalCommand) that uses sshfs to mount a server directory on the client. Then a server script can simply copy a file to the mounted directory and it will be visible on the client. Job done..., or not. There are problems with this however. Firstly as I often have several ssh connections running at the same time there needs to be some way to prevent the LocalCommand running multiple sshfs instances. This isn't too bad to overcome but the second issue is how to pull down the sshfs connection when the last ssh exits, at present I can't see any way to do this, there isn't the equivalent of LocalCommand which runs when a connection is about to be closed. Does anyone have any ideas which might help? -- Chris Green

I don't have Flash installed so I'm not able to 'measure' Adobe documents and it turns out this could be useful in some circumstances. Does anyone know of a Linux tool one could uses for this? Bev.
