Bash flaw - uh oh
by Bev Nicolson 29 Sep '14

What should we do? Here it's just me and my computer to worry about for example and I have a firewall and a virus checker installed. Is that enough? http://www.bbc.co.uk/news/technology-29361794 Bev

Phone backups
by Chris Walker 28 Sep '14

28 Sep '14

Hello, I have a Jolla phone which runs linux. Unfortunately the speaker has stopped working which rather renders it useless as a phone so it has to go back to Finland for repair. Jolla have suggested I take a backup as they will reset it and wipe it. But their backup doesn't backup everything so can I copy everything off it perhaps from this machine? I easily ssh into the phone as a user and then switch to 'devel-su' mode but I don't appear to be able to ssh into it as root. I've tried to run scp from within the phone (using ssh) to a NAS drive but I can't make it connect. At this stage I'd rather not install loads of extra software on the phone just to do the backup so any ideas about copying everything off the phone before it goes back would be appreciated. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

device only (or caldav) calendar on android
by mick 24 Sep '14

24 Sep '14

Hi Guys I have just bought a new mobile (dual sim Moto G) to replace both my main 'phone and a backup. I am /not/ a huge fan of Google, but since I hate apple even more, the android device offers me the best functionality for the least inavsion of privacy (within limits). Before even transferring my personal data I locked the damned thing down to try to prevent as much google synchronisation as I could (but still, stupidly, managed to let the bloody thing send my contacts because I mssed one of the buried sync settings). That aside, I now really want to move my calendar data to the new device. Previous devices (from HTC, Sony and Samsung) have allowed me to set up a local, "device only" calendar. This new one won't and insists that I link in a google account before I can add /any/ data at all. So I'm looking for an alternative app. What I'd really like is a CalDav style application which allows local only storage on the 'phone, but will later allow me to sync to my own server (when I finally get around to setting up owncloud). Any and all advice (short of "throw the 'phone away") gratefully accepted. Most of the calaenadrs on the google play site appear to be little more than alternative skins to the underlying android calendar.

How to change ssh destination depending on connected LAN?
by Chris Green 23 Sep '14

23 Sep '14

As I move around from home to various other places different systems that I connect to from my laptop become 'local'. Being a lazy person I really don't want to type in long complicated ssh commands when I'm connecting remotely. Thus I have in the ~/.ssh/config file the following:- Host cheddar HostName cheddar.halon.org.uk Host halon HostName cheddar.halon.org.uk Host chris ProxyCommand ssh cheddar nc -q0 zbmc.eu 22 Host odin ProxyCommand ssh cheddar nc -q0 localhost 51234 This means I can simply type 'ssh chris' or 'ssh odin' and ssh with the above config file does all the hard work for me. However it means that when I'm at home for example (where 'chris' is my desktop on the LAN) if I type 'ssh chris' I get connected to my desktop machine via the internet which is rather ridiculous. Can anyone come up with an easy way to change how 'ssh chris' acts according to whether I'm on the LAN where 'chris' is or not. Similarly I want the same to happen when I'm on the LAN where 'odin' is (which is not the same LAN). -- Chris Green

My question was really how to automate the switch over by (somehow) detecting whether I'm connected to the LAN or not. -- Chris Green

The specific issue is because of my use of ProxyCommand in my ~/.ssh/config file. It's *not* "how do I get local names to work". -- Chris Green

mp3splt and regex
by Chris Walker 22 Sep '14

22 Sep '14

Hello, I'm struggling to split an mp3 file and simultaneously enter some tags in to the output. The input filename which is a get_iplayer download looks like this 'David_Rodigan_-_02_09_2014.mp3' and my problem is adding tags to the output. How do I make 'David_Rodigan' appear as 'title' in the output tags? I guessed that David would appear as first_part and Rodigan as second_part but I can't see a way to concatenate those two items to form title. My attempt looks like this :- mp3splt -G (?<title>):first_part+" "+second_part David_Rodigan_-_02_09_2014.mp3 3.00 60.00 -o /split/David_Rodigan_-_02_09_2014 But that fails with bash: syntax error near unexpected token `(' I'm looking at this page for inspiration but it isn't helping! http://mp3splt.sourceforge.net/mp3splt_page/documentation/man.html Perhaps somebody here can explain where I'm going wrong please? -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

Any idear how this router running Linux configures itself?
by Chris Green 21 Sep '14

21 Sep '14

I have a little Solwise 3G router on my boat. I have just discovered it runs Linux and I can telnet into it. Even better it runs dnsmasq so, if I can configure it appropriately then I can get it to provide local DNS. However I can't work out where it configures itself from at boot time. If I edit /etc/hosts for example then, if I reboot, my changes are lost. There's an /etc_ro directory but nothing really much in there gives a clue. There's even an /etc_ro/rcS file which is obviously executed fairly early on in the boot sequence but it's not early enough to indicate where the basic configuration lives. The motd file says:- ------------------------------------------------------ Welcome to HAME Technology Co.,Ltd =System Architecture Department= ------------------------------------------------------ ... oh, it as busybox for most of the commands. Does anyone have any idea how it starts up and configures itself? -- Chris Green
