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

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

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
