MS Office file formats
by Phil Thane 12 Jun '17

12 Jun '17

I've used Star Office / Open Office / Libre Office for all my writing work since around 2000. Most editors though want work in MS file formats, previously .doc, now .docx. I notice that Libre Office 5 'save as' function gives me the option to save in MS Word 2007 - 2013 XML (docx). Does anyone know if that's the latest? What does the new-fangled 'MS Office as a Service' use? Are we going to run into compatibility issues all over again? -- Phil Thane www.pthane.co.uk phil(a)pthane.co.uk 01767 449759 07582 750607 Twitter @pthane

Get the new machine sorted first, then either: boot up a live CD on the victim and export the local storage to the new machine (probably using the nice easy GUI 'sharing' stuff in Gnome these days); or remove the physical disk(s) and attach to the new machine via a USB caddy / directly into a disk slot if you have one spare, this may be easier than trying to get sharing guff to work. Either way, you can copy off the whole VirtualBox VMs folder from the victim's storage, then work on a nice new/fast/not-broken machine to get them going again. I use a similar approach to properly scan machines for malware, on the basis that one should never try and scan from within the possibly compromised OS. I export the raw disks using a live CD to another machine and scan from there. Cheers, Phil.

Any DNS/systemd experts here? I have a DNS problem on new xubuntu install
by Chris Green 08 Jun '17

08 Jun '17

My new laptop has xubuntu 17.04 installed and that runs systemd-resolved for local DNS rather than the previous dnsmasq (run by Network Manager). I have a local server on my network that provides DHCP and DNS for the systems on the LAN and thus I can find things by name. From all my older (xubuntu 16.04) systems this works for both unqualified and FQDNs:- chris$ host backup backup.zbmc.eu has address 192.168.1.101 chris$ host pi pi.zbmc.eu has address 192.168.1.2 chris$ host backup.zbmc.eu backup.zbmc.eu has address 192.168.1.101 chris$ host pi.zbmc.eu pi.zbmc.eu has address 192.168.1.2 chris$ However, from the xubuntu 17.04 system, it doesn't work for unqualified names:- chris@t470$ host pi Host pi not found: 2(SERVFAIL) chris@t470$ host backup Host backup not found: 2(SERVFAIL) chris@t470$ host backup.zbmc.eu backup.zbmc.eu has address 192.168.1.101 It looks like it should work because systemd-resolve's configuration seems right:- chris@t470$ systemd-resolve --status Global DNS Domain: zbmc.eu DNSSEC NTA: 10.in-addr.arpa 16.172.in-addr.arpa 168.192.in-addr.arpa 17.172.in-addr.arpa 18.172.in-addr.arpa 19.172.in-addr.arpa 20.172.in-addr.arpa 21.172.in-addr.arpa 22.172.in-addr.arpa 23.172.in-addr.arpa 24.172.in-addr.arpa 25.172.in-addr.arpa 26.172.in-addr.arpa 27.172.in-addr.arpa 28.172.in-addr.arpa 29.172.in-addr.arpa 30.172.in-addr.arpa 31.172.in-addr.arpa corp d.f.ip6.arpa home internal intranet lan local private test Link 3 (wlp4s0) Current Scopes: DNS LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no DNS Servers: 192.168.1.2 8.8.8.8 DNS Domain: zbmc.eu Link 2 (enp0s31f6) Current Scopes: none LLMNR setting: yes MulticastDNS setting: no DNSSEC setting: no DNSSEC supported: no Hey!

Can anyone point me at a VLAN tutorial aimed at small 'soho' users?
by Chris Green 07 Jun '17

07 Jun '17

I'm trying to use VLANs to separate areas of my home LAN, mostly for security by, for example, keeping guest/Windows WiFi connections isolated from the rest of the system. It appears that just about every manufacturers' idea of what VLAN means is different! I have VLAN ability offered by my TP-Link VDSL router, by my Draytek Vigor 2820n router and by a TP-Link TL-SG108E managed switch. They all seem very different! On the TP-Link router (TD-W9980) the VLAN facility is closely connected with what it calls LAN groups. You can create groups and put the physical LAN ports and WiFi SSIDs into specific groups. Each group has its own DHCP server and thus a different IP range. You can't put anything (LAN port or SSID) into more than one group. In reality there seems to be little real separation between groups as, if you put (say) LAN port 2 into a group by itself any device connected to LAN port 2 will still get replies DHCP requests it sends from any/all the other LAN ports. A different subnet will run on LAN port 2 but if you configure a device connected to that port with a different subnet address it will happily talk to devices on the other ports. The 2820n is quite different. If you set up VLANs on that they all have the same DHCP server (in the 2820n) and are thus on the same subnet, but they are separated and unable to communicate with each other. Devices can be assigned to multiple ports. Thus it's possible to have one VLAN (to which everyone can belong) that has access to the internet and not much else and another VLAN which is the more secure internal VLAN. Finally the TL-SG108E offers three sorts of VLAN - Port based, tagged and MTU (confusing abbreviation that last one, it doesn't mean Maximum Transmission Unit). The manual isn't very helpful, it does the usual TP-Link thing of repeating what the words on the GUI confuguration tell you with no indication of *why* you would want to do anything. Port based VLANs are a bit like the 2820n ones described above except that they seem to expect different subnets, the others I'm not really sure about (as in I don't really understand them) but looking around the internet I gather that the descriptions confuse others too because they don't use the same terms for the same things as others (mostly Cisco) do. Help! :-) I just need a simple explanation of how to split up my LAN such that I can separate a 'Guest WiFi' part (more than one WiFi device), an area that all local users can access (with printer, DNS, etc.) and a more private area (my desktop, backup system, etc.) that only I can access. All users need access to the internet of course. -- Chris Green

I have bought my laptop replacement
by Chris Green 03 Jun '17

03 Jun '17

Well after much timewasting searching web sites, reviews, etc. and listening to advice here and elsewhere I have bought my replacement laptop (to replace my Thinkpad T430). I decided to stay with Thinkpad Txxx as reviews indicate they are some of the best machines around *and* they are good for Linux. Rather more in hope than expectation I bid for a T470 on eBay and got it for £650. The T470 is the current T series model and this one has a latest (7th) generation Core i7 processor, 8Gb memory and a 256GB SSD. It is ex-demo and thus virtually unmarked and comes with a full 3 year on-site warranty! New price is around £1500. Wow! :-) I have installed xubuntu 17.04 on it and it's lovely! :-) -- Chris Green

Which laptop to buy, help me decide
by Chris Green 29 May '17

29 May '17

Having increased my budget somewhat I seem to have narrowed my choice of laptop on which to run Xubuntu to one of the following two:- A - pcspecialists/novatech/entroware custom system:- https://www.entroware.com/store/orion https://www.pcspecialist.co.uk/notebooks/ultraNoteIV-14/ These are all the same machine built by Clevo and configured by the various companies above. Pcspecialists are cheapest. For my 8Gb, Core I5, SSD machine the cost is around £540. B - A Lenovo Ideapad 510S http://www3.lenovo.com/gb/en/laptops/ideapad/500-series/Lenovo-IdeaPad-510S… Price (if you shop around) a little less than the one above. I've checked and according to Lenovo forums etc. Ubuntu Linux installs on it without problems. Does anyone have any comments about either of these machines that might push me one way or the other? -- Chris Green

Has anyone heard of Entroware?
by Chris Green 29 May '17

While searching for my new laptop I came across this company:- https://www.entroware.com They build and sell Ubuntu OS laptops and the prices are not unreasonable. Does anyone know anything about them or has anyone here bought one? -- Chris Green

Nedd new laptop AND seek rcovery of files from VirtualBox
by Ted Harding 27 May '17

27 May '17

Greetings All! Chris Green's recent message arrived as I was about to compose a similar one! My (somewhat ancient but much-loved) Advent 8117 recently crashed. It had Windows XP, into which I installed VirtualBox into which I then installed Debian (Etch, I think; and Ubuntu). It is the Windows, apparently, which crashed. While, after repeated attempts, it is possible to get windows started, many of the applications icons have vanished rom the screen, including the VirtualBox one. So Linux is now inaccessible on this machine. Yesterday I took it to be looked at by a Computer Suppport person I know (very amiliar with Linux), and we did get somewhere -- using a Slackware Live CD it was possible to have a look at the filesystem. However, when I tried to reboot it just now nothing happened: no sign of power reaching the compuyer (and the battery is dead anyway). I suspect that yesterday's 60-mile round trip may have broken a power-supply connection somewhere in the computer. So FIRST: I'm seeking a replacement. No special hardware requirements beyond a good amount of HD space and of RAM, plus the usual ethernet cable, print (via USB cable), USB ockets etc. And a nicely laid out keyboard with very visible labels (letters etc.) would be very welcome. especially if the "delete" key is at bottom right instead of top right. I'd like it to have Linux installed, preferably Debian, but with Gnome 2 desktop rather than later versions (Fermilab's Scientific Linux has stuck with Gnome 2), since the way I work depends heavily on the array of workspaces displayed at the bottom of the screen in Gnome 2. So any suggested offers? (willing to pay a reasonable price). Then SECOND: I really want to recover files in the Linux systems which have accumulated over the years (not fussy about the entire OS's, though some of the system config files are also important). The Linux filesystems are in VirtualBox ".vdi" files on the Windows XP system, which I was able to locate after booting with the Slackware CD. I've been looking around extensively for info about how to set about this. This does not seem to be straightfoward unless the VDI file is transerred (somehpow ... ) to another machine on which VirtualBox is installed. Any help or advice? With thanks, Ted.
