Any ideas how to provide a WiFi connection that goes via a proxy?
by Chris Green 30 Sep '19

30 Sep '19

I'll try and explain what I need. I want to connect a WiFi device (a Kobo eReader) via a proxy server so that it will appear to be in the UK even when I'm on my boat in France. This is because downloads of books from the library will only work when the Kobo eReader is in the UK. I'm not trying to cheat or anything, I just want to be able to check out new library books to read when I'm away from home. The Kobo only has WiFi, no wired connection, so it needs some sort of WiFi source to connect to which will (presumably) in turn be connected to a UK based proxy server. I can provide the proxy server myself, I often do this for browser connections to order my repeat prescriptions (for some reason my doctor's web site won't allow connections from outside the UK). So, I guess, I need something like a wireless router which can be set up to route *all* WiFi clients via my UK proxy. Or am I barking up the wrong tree? (I don't really know what ports/protocols the Kobo uses though I suppose I could find out) Any/all ideas welcome. -- Chris Green

Laptops for Linux
by Mark Rogers 13 Sep '19

13 Sep '19

Before Christmas I bought myself a new Lenovo laptop thinking I'd get Ubuntu running on it fine, but no; graphics issues, touchpad issues, etc and it's been running Windows 10 ever since. So as not to make the same mistake again, on a budget of about £450 what is a good laptop for Linux? Happy to look at 2nd-hand or refurbs, Must haves: It's for my wife so it needs a numeric keypad (she's a bookkeeper). A side effect of that means 15"+. Needs to run virtual machines (Sage only runs on Windows...). Weight is a factor, I think certainly <2kg. It'll end up with SSD either because it came with one or I installed it (happy either way, probably prefer to install it myself). Decent RAM - I'd have thought 16GB (or at least the scope to increase it later). Can claim the VAT back so budget is higher with a VAT invoice than without.

Basic image manipulation
by Mark Rogers 09 Sep '19

09 Sep '19

Probably 90% of my image work is taking an image (maybe a screenshot or photo), making some very basic changes like rotate, crop, scale (usually to reduce filesize), and saving it. I seem to have a collection of tools which view only (like EoG) but load instantly on minimal resources, and sophisticated apps like GIMP which will do anything I might ever need but more slowly. What's a good app for every-day image stuff like this? I'd accept - and even quite like - a few extra bells, like highlighting/blurring/annotating, as long as it doesn't become cumbersome to use or slow to load. <rant>Bonus for something which doesn't give me a single "rotate 90deg" option; why does eveyone expect me to do three rotates instead of one?</rant> -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Hardware upgrade?
by Phil Thane 05 Sep '19

05 Sep '19

Hello folks, Looking for hardware advice. My desktop PC hasn't had a hardware upgrade for about 5 years when I bought a MoBo bundle and a secondhand graphics card. It's an AMD Quad core CPU running at 3200MHz with 2G of RAM and Nvidea GE Force 8400. For the most part it's OK, I don't do video editing or gaming so it doesn't work too hard. The graphics card has always been an issue though, it refuses to run 64bit Linux distros. I've tried several in the past, Debian-based and others, and always get the same result, installs OK but on boot just gives a black screen. Annoyingly it will run 64bit distros from DVD so you think it's going to be OK after an install, but it isn't. It hasn't been too much of an issue running 32bit versions until recently but it seems they are being phased out. I'd like to try KDE Neon for example, but there is no 32bit version. So: Any recommendations for a cheapish graphics card that will work? Is it worth getting 4GB or more RAM? -- Phil

Simple multi-line string manipulation from bash
by Mark Rogers 04 Aug '19

04 Aug '19

I have a simple bash script for locating Raspberry Pis on the network: #!/bin/bash PIMAC=B8:27:EB sudo nmap -sP 192.168.251.0/24 | grep -i " $PIMAC" -A0 -B2 Whilst the output gives me the answer I want I'd like to tidy up the formatting. The current result is: Nmap scan report for 192.168.10.20 Host is up (-0.10s latency). MAC Address: B8:27:EB:22:1C:05 (Raspberry Pi Foundation) -- Nmap scan report for 192.168.10.24 Host is up (-0.10s latency). MAC Address: B8:27:EB:22:1C:05 (Raspberry Pi Foundation) What I want out of it is something more like: MAC Address: B8:27:EB:22:1C:05 (Raspberry Pi Foundation) IP Address: 192.168.10.20 IP Address: 192.168.10.24 What is the best way to do this? Or should I just ditch the bash script for a Python script? -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

I've never found a good way to treat an entire OS as a repository (or just the customisations, given that they can be anywhere in the system). I do maintain a list of changed files which I use to create tar based backups (different files from the subject of this thread), as well as an init script listing all the packages I need installing, but inevitably I sometimes forget to add something to my list. (It would be nice to think that a development workflow is "I need this, so add it to my list and install it". But reality is more like "I wonder if this will work, I'll install it and try" or "Let's install several options and see which works out best". With the best will in the world, being at least able to validate the list afterwards is useful.) > [...] > "apt doesn't remember which reverse dependency caused it to install rsync, but it does log all its actions in /var/log/apt, so you might find the dependency there: > [...] > That may help a bit, but it depends on what period the log-rotated apt log files you have. /var/log/apt/history.log is useful but isn't exhaustive because of the reason you elude to. I have certainly made us of it in the past though. A bigger problem for me here though is that /var/log is excluded from my tarball backups... Regarding dependencies: I would be nice to know why I installed a package, but for now just merging 400+ file differences into one package install is a big step forward. The example I gave some way back was netpbm - I never installed it directly, it turns out that it was because I installed a screenshot package, but given that any report will also list the screenshot package I can likely work that out later. > It seems to me it would be easier to work out using apt/aptitude etc on a live system - (see the search I mentioned earlier - lots and lots of lovely links, methods etc) > It seems to me it would also be easier to keep a manual list of top-level changes. Easier, sure, but where's the fun in that! But actually: By "easier", what this means is restoring a multi-GB backup to an SD card, booting a Pi from it, running some commands to get the package list etc, copying the result back to my desktop, then repeating the entire process with the second backup, before I can diff anything. So easier, but not quicker :-) PS: Perhaps inevitably most of my reply is "yes, but that won't work because..." which obscures the genuinely useful information you gave me, a lot of it new to me. Thank you very much for that, it helps more than the above reply might suggest. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Getting package name from file path, offline
by Mark Rogers 08 Jul '19

08 Jul '19

If I have a list of filenames (with paths), what's the best way to work out what package most likely provided them? This will be offline, so I can't use dpkg -S etc. The original O/S is Raspbian if that helps. (Background: I'm trying to look at SD card backups and work out what packages were installed without booting them.) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
