Amber intends to combat encryption!
by Phil Thane 19 Dec '17

19 Dec '17

I've been having 'fun' corresponding with my MP (Burt, con) and our much-loved Home Secretary about her plans to ban encrypted messaging. The gist is here, with links: https://pthane.co.uk/blog/ Scroll back a bit for the first installment. Feel free to register and comment, I don't claim to be an expert, I could well be wrong, but it seems I know more that the Home Office. -- Phil Thane www.pthane.co.uk phil(a)pthane.co.uk 01767 449759 07582 750607 Twitter @pthane

Restarting wifi and network on a headless Pi
by Mark Rogers 14 Dec '17

14 Dec '17

I don't know if this is Pi specific, I assume it's just standard Debian. I'm using Raspbian Stretch. Suppose I have a working wireless connection. I can change wireless configuration in /etc/wpa_supplicant/wpa_supplicant.conf to remove the working details and then use "wpa_cli reconfigure" to take effect. Except that I remain connected to the wifi that I no longer have settings for, and cannot force it to disconnect. What is the correct way to force the change to have effect other than reboot? On a related note, how do I change the IP configuration for the cabled network and have that take effect? Making changes to /etc/dhcpcd.conf works after a reboot but I can't reliably make it work without rebooting. (Restarted dhcpcd will add a new IP address, but won't remove old ones and doesn't seem to let me revert to DHCP reliably either.) In both cases, making a connection seems easier than dropping one.

Are there *any* decent web browsers out there now?!?!
by Chris Green 11 Dec '17

11 Dec '17

I'm finally getting a bit fed up with Firefox, for a couple of reasons:- It's seems incapable of working with eBay without going to 100% CPU and slowly grinding to a halt. The last few updates have made it *look* decidedly clunky. Arcane configuration parameters required to make it so it can open files on one's local file system. So, I've been looking at alternatives and there's not much that seems any better (they have different issues in the main). I've been trying chromium and it certainly seems faster than Firefox and doesn't seem to grind to a halt on eBay, but:- I want a separate search bar You can't change the keyboard shortcuts Is anything else any better? I've been wondering about Vivaldi, same underlying engine as Chromium but apparently much more configurable. Has anyone here tried it? I'm just a bit wary of going 'off piste' as it were (not in the Ubuntu repositories). -- Chris Green

How to allow easy editing of www-data owned files - or other workarounds?
by Chris Green 11 Dec '17

11 Dec '17

I've been trying to find a good solution to this problem for *years* but I'm still hitting problems with it. The current problem is that syncthing doesn't deal well with directories and files which have different owners on different systems. The essential problem is that web files which are manipulated by apache need to be owned by www-data but I want to be able to edit these files as well. In particular I have a wiki where I sometimes edit the files using the wiki (ownership ends up as www-data) and sometimes I edit them directly with an editor (ownership ends up as chris). Currently I use access control lists (setfacl) to make things so that both chris and www-data can both manipulate files in the wiki directory regardless of whether they are owned by chris or www-data but this isn't a perfect solution as the correct settings don't always get put on new files. What I really need is:- All the wiki files are owned by 'chris' (the wiki is rooted in my home directory and is synchronised across a couple of machines by syncthing). www-data can read/write/create files in the ~/chris/wiki directory but they will always be owned by 'chris'. Can anyone see a way of implementing this? ... or any other reasonable solution? -- Chris Green

Audio Question
by Ben Whyall 05 Dec '17

05 Dec '17

Hi I have a query which whilst not 100% linux I suspect someone might be able to help. I want to be able to somehow share speakers, and headphones/headset between two systems. Ideally I want to be able to decide what output is in use by ficking a switch or something similar not unplugging. Same with the input. One machine is a linux box and one is my work laptop (windows 10) What are peoples thoughts? Ben

Firefox 57 woe
by Bev Nicolson 30 Nov '17

30 Nov '17

I had hoped to be prepared for whenever the upgrade to Firefox 57 occurred but it turns out I haven't been. This is because the Software Updater hadn't offered 57. Anyway, it seems I have lost all my ScrapBook pages. Or at least, the question I want to ask is, how can I find out for sure that I have? The home and computer directory have been searched for 'firefox data' but no dice. Bev.

ssh_config file equivalents of command line options - how to find?
by Chris Green 30 Nov '17

30 Nov '17

I had a hard time recently working out what the ssh_config file equivalent of the -L command line option in ssh was. The man page happily tells you that "Port forwardings can also be specified in the configuration file." buut doesn't tell you *what* the configuration file equivalent is. (It's actually a bit obvious - LocalForward). Is there any documented way of finding the mapping? I'm now after the config file equivalents for -f and -N if there are any. -- Chris Green
