USB Backup Disk problems
by steve-ALUG＠hst.me.uk 08 May '17

08 May '17

Hi Geniuses! I have a 2TB Seagate USB disk that is being used with backuppc to store daily backups. However, almost every day the backup is failing, and attempting to ls the drive gives "input/output error". Looking through DMESG shows multiple problems reading sectors on the disk, but I've yet to find a particular cause. If I reboot the machine, the drive immediately starts working again. If I fsck it, it reports no errors. The disk has two partitions on it, and the 2nd partition is used by SimpleBackup, and this seems to work fine. I'm currently backing up the backup before I do some more in-depth testing on it, and possibly reformat it. I forgot to mention that both partitions are encrypted. Do people think the disk is broken (bad sectors or hardware problems), or if not, any idea what's going on? On to the next problem. I bought a different 2TB Seagate USB 3 disk which I was intending to use to replace the problematic disk. I managed to set up encrypted partitions on the new disk, and configure the computer so that they would automatically mount on boot.... so I tried to boot the machine and.... the BIOS screen appeared, then it said detecting devices... The old faulty drive is detected, but then the USB 3 Driver is not detected and the machine hangs. It's simple, with the drive connected at boot, the machine won't boot or detect the drive. Without the USB3 drive connected, the machine boots fine. I'm guessing that the machine, which is quite old, can't cope with something about the new drive, perhaps it's slightly too big (although they're both ~2TB), or because it's USB3, and I think the old one is USB2. The old one has a power supply, but the new one doesn't, but I tried connecting it via a powered hub, and no difference. Is there any way round the machine not booting? I don't think there's a updated bios for this old machine. Any ideas, straws to clutch at? Steve

HMRC payroll software and zlib
by Jenny Hopkins 02 May '17

02 May '17

Hi all, I'm attempting to set up payroll on debian jessie using the HMRC's payroll software for linux. When I try and run it, however, I get the following error: zipimport.ZipImportError: can't decompress data; zlib not available Fatal Python error: unable to locate initialization module I've installed these packages, but no change. libjzlib-java zlib1g:amd64 zlib1g-dev:amd64 zlibc Following a similar thread for this error, I ran python and got the following info: >>> zlib.__version__ '1.0' Any ideas on what else I need to install, or what the problem could be? Thanks, Jenny

DNS lookups with systemd-resolve (Ubuntu 17.04)
by Mark Rogers 24 Apr '17

24 Apr '17

I have a local DNS server, and in it are several hosts, specified both with and without a domain name. Eg: $ dig @192.168.1.5 myhost ... ;; ANSWER SECTION myhost. 0 IN A 192.168.1.123 ... $ dig @192.168.1.5 myhost.mydomain ... ;; ANSWER SECTION myhost.mydomain 0 IN A 192.168.1.123 However, if I don't specify the DNS, the first query (myhost) times out, where the second (myhost.mydomain) still works fine. My PC gets its DNS settings via DHCP. /etc/resolv.conf contains only 127.0.0.53 which as I understand it is systemd-resolve. /run/systemd/resolve/resolv.conf contains only 192.168.1.5 (my DNS). So, in the case of a query for "myhost.mydomain", systemd-resolve is correctly passing the query on to my DNS. But in the case of "myhost" it is not (I don't know what it is doing instead). If I try "ping myhost" I get "Name or service not known". Similarly, if I try ssh mark@myhost.

Mesh wireless
by Mark Rogers 24 Apr '17

24 Apr '17

I started looking at a few commercial mesh wireless products, which typically retail at around £300-400 for a typical house. I then Googled and discovered a few Linux mesh wireless projects, such as might suit running on a Pi. Anyone here have any experience of such things? (The biggest obstacle with the Pi is likely to be the slow Ethernet port but there are faster single board computers around that might work better. Regardless, the Pi might be a good place to start playing.) -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

Shutdown!

Using Mint 18.1 on my laptop, when using 'shutdown' it does just that, but then reboots a few seconds afterwards, every time recently! Tia, Michael -- Michael Goddard <emmjee(a)mypostoffice.co.uk>

Writing to Google Sheets from bash
by Mark Rogers 07 Apr '17

07 Apr '17

I don't suppose anyone here has any experience of writing to Google Sheets from bash? (Specifically, I'm trying to use curl to write values into a pre-existing spreadsheet.) I started with a fairly simple aim: To have a few Linux boxes (servers, Pi's, etc) periodically update a central spreadsheet with stuff like disk utilisation, updates pending, O/S version, etc. However I haven't had to deal with OAuth2 before and I'm going round in circles trying to find out exactly what authentication I need to configure. My attempts at Googling have lead me into most of those circles without getting me out again! It seems like a useful concept to pursue but I have to admit I'm just way out of my depth! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
