KVM/QEMU
by Mark Rogers 02 May '23

02 May '23

I've used VirtualBox for years, most recently either as a desktop tool (eg on a laptop) for testing things out (managed by the VBox GUI), or as a server tool hosting multiple VMs (managed via a combination of CLI and the web-based phpVirtualBox tool which mimics the VBox GUI via a web interface). For a long time I've thought I should use KVM instead so today I had a crack as installing it on my home Linux server (Ubuntu) but I've gone around in circles and got nowhere useful. What do I need to do to achieve something simple like creating a new VM, booting it from a Windows ISO and installing Windows 10 on it? I need to do it all from the command line or via a web interface - preferably having both options open to me. The server is headless so a traditional GUI is no use to me. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

No pdf thumbnails
by Bev Nicolson 15 Apr '23

15 Apr '23

I'd not been having any trouble with pdf's for a while but suddenly no recent pdf's show a thumbnail, just an Adobe logo. I've got Master pdf and the simpler Evince (for when I just want to read something.) In the past, if this happened, all I had to do was change the file name and then a thumbnail would appear. That doesn't work here. (I think I've asked a similar question before but on hunting through the archive couldn't see a clear answer.) Bev

I'm looking for a hosting service for a few web sites that I maintain for friends and family. One possibility is QA Webhosting who seem to be quite small but offer just about exactly what I want/need. Does anyone here know anything about them? -- Chris Green

Linux Tablets
by Peter Berrie 22 Mar '23

22 Mar '23

I recently had occasion to wish, yet again, that I had a proper Linux tablet. So afterwards I dug out an old Linx 8 windows tablet and tried various distros on it. It came with windows 8, which was pretty bad, and I had upgraded to windows 10, which is better but glacially slow. I tried various distros on it including several Puppies, some of which not bad but no touch support, Fedora, which would not finish booting, slitaz (failed to boot), MXlinux (no touch). Several others. Zorin (failed to boot). A desktop derived from Alpine. So far the best I have found is Peppermint 32 bit. XFCE. Touch works, it sees battery status, its reasonably fast considering the hardware. I haven't got on screen keyboard yet, but there seem to be several choices of this. My impression is that it would be a viable solution on a more recent and powerful x86 tablet. But which? I'm thinking now about getting a used Surface. It seems like the Surface 5 is the best choice among them, apparently a significant improvement on the model 4, and that it should work with Linux. It should be able to manage Fedora which is widely recommended for touch devices. There is also a Lenovo with detachable keyboard of lower cpu spec and similar vintage, at about the same price. Lenovo Ideapad Miix 700. Bigger screen. The Surface 5 seems to have been a significant upgrade from the previous Surface 4. Do you all have any thoughts about this? Any other x86 tablets to consider? Any other distros that are more promising than Peppermint? Is Chrome worth considering? Peter

gmail bouncing emails from my domain.
by Nev Young 13 Mar '23

I suspect this is a naive question but I'm at a loss how to fix this. I send emails using thunderbird and msmtp. I post via my ISP's smtp server (smpt.zen.co.uk) This has allowed me to send emails to any one as any one. e.g. this has come from alug(a)nevilley.org.uk very recently emails sent to gmail users have started to bounce undelivered with the likes of: (email address redacted) This message was created automatically by mail delivery software. A message that you sent could not be delivered to one or more of its recipients. This is a permanent error. The following address(es) failed: ##############(a)gmail.com host gmail-smtp-in.l.google.com [108.177.15.27] SMTP error from remote mail server after pipelined end of data: 550-5.7.26 This message does not pass authentication checks (SPF and DKIM both 550-5.7.26 do not pass). SPF check for [nevilley.org.uk] does not pass with ip: 550-5.7.26 [212.23.1.22].To best protect our users from spam, the message has 550-5.7.26 been blocked. Please visit 550-5.7.26https://support.google.com/mail/answer/81126#authentication for more 550 5.7.26 information. p9-20020adfe609000000b002ca647fe919si1349235wrm.527 - gsmtp Do I need to do something with thunderbird on my PC or is this a problem for Zen? Any help gratefully received. Nev

Hi, Some one (not me) has been "messing about" !! During a phone discussion with [1] at fasthosts we retried sending the previously bouncy emails. AND THEY WORKED !! The magic gremlins appear to have fixed it. What can I say? Thanks to all who put in effort. (no doubt it'll break again tomorrow) Nev On 06/03/2023 17:17, steve-ALUG(a)hst.me.uk wrote: > On 06/03/2023 16:54, Nev Young wrote: >> Hi Steve, >> >> This is too hard for my ikkle brain. > > Hi mate. > > Will have a look and get back to you. > > Just a mo... > > Steve

HP Microservers or similar
by Mark Rogers 20 Feb '23

20 Feb '23

Over the years I've used a handful of HP Micro servers to run a Linux-based web server application. To be honest I suspect it would comfortably run on a Pi, to give you some idea of power requirements. However it does need to be dependable and one of the criteria is RAID (software RAID 1 is fine). We replace the hardware every few years so the question I have is: what is a good small server for Linux these days? Apart from the requirement to host 2 SATA drives there isn't much in terms of hardware requirements. We don't even use a lot of disk space - maybe a few dozen GB. One HDD gets replaced annually so that no disk is older than 2y, using commodity disks in the 1-2TB range but partitioned to only use 200GB on each disk, just because we don't need more and it makes the swap to a new disk quicker. Hot swap not needed. Would consider SSD for the new server. I was about to get a quote for an HP Gen10 MicroServer when it crossed my mind that maybe just buying the same server out of habit wasn't necessarily the right approach! -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0344 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER

SPF Record problem
by steve-ALUG＠hst.me.uk 17 Feb '23

17 Feb '23

Hi all I have just seen a message saying that Gmail is going to reject all emails without an SPF set up, so I thought I'd try for my mail server. Of course I have immediately run into trouble. My email gets sent via a virgin media server, currently smtp.ntlworld.com but I may update to smtp.virginmedia.com in future I used an SPF Wizard https://www.spfwizard.net It generated v=spf1 mx a a:smtp.ntlworld.com a:smtp.virginmedia.com ~all which if I read it right, accepts my domain, or smtp.ntlworld.com or smtp.virginmedia.com as valid email handlers for my email, with a "soft fail". [I used a soft fail for debugging - I want to swap to hard fail, but can't until I get this right] I've sent a couple of emails to test, and here's the snag. By the time they get to google, they're coming from 212.54.57.96 212.54.57.97 If I do a whois on that, I get back ziggo.nl (VODAFONEZIGGO) I expect email to smtp.ntlworld.com gets redirected to another server, or group of servers, inside virgin media, no doubt with a name like MAILSERVER.virginmedia.com (for some value of MAILSERVER), and that's handled by a range of IP addresses. How can I craft a valid SPF record, if I don't know which IP addresses or name to put in the spf? Why is virgin media mail ending up on a server in NL, or is that just an out-of-date or wrong whois lookup? Any ideas????? I'm struggling! Steve
