rsync
by Phil Thane 18 Nov '19

18 Nov '19

I'm sure this is trivial but I don't know where to look... My wife's PC uses Grsync (gui for rsync) to backup to my server. I've recently put a new HDD in the server and re-installed everything, including a new SSL cert via Certbot. Now her Grsync refuses to connect because the certificate has changed. I guess sudo apt purge grsync then re-install it would do it but is there a more elegant method? Some config file I can edit or delete? -- Phil Thane www.pthane.co.uk Tweet @pthane 01767 449759 07582 750607

Question about PCIExpress slots and SSDs
by Chris Green 15 Nov '19

15 Nov '19

I have a Fujitsu Esprimo P910 system to which I am thinking of adding a bigger SSD. It already has a 128Gb SSD for the OS but that is just an 'ordinary' 2.5" SATA one that I simply connected to a SATA interface and thus it runs at maximum 600MB/s. The motherboard has unused PCIExpress slots as follows:- PCI-Express 3.0 x16 1 x (312 mm / 12.29 inch) Full height PCI-Express 2.0 x4 (mech. x16) 1 x (312 mm / 12.29 inch) Full height PCI-Express x1 1 x (312 mm / 12.29 inch) Full height PCI (32-bit / 33 MHz) 1 x (170 mm / 6.7 inch) Full height Now I know I need an adapter to plug a 'PCIExpress' NVME SSD into one of these slots but they're not all that expensive, e.g.:- https://www.amazon.co.uk/Adwits-Express-PCIe-based-Adapter-Factor-PCIe-x16-… So, if I get something like the above (alternative recommendations welcome) will I be able to get a fast[er] NVMe SSD and have it "just work" or are there BIOS and OS ramifications? I'm currently running xubuntu 19.04 with a 5.0.0 kernel. -- Chris Green

Looking for new[ish] desktop machine as my main machine
by Chris Green 10 Nov '19

10 Nov '19

I'm thinking that I ought to replace my current desktop machine with something a bit faster and (maybe) less power consuming. My current desktop is a Fujitsu Esprimo P910 with a small (128Gb) SSD and several spinning hard disks. This machine stays on all the time as it's my mail server that I ssh into to read my mail whci it receives using SMTP. So I'd like to get something at least as economical (power wise), the P910 which idles at about 22 to 24 watts So requirements for new machine are:- Idle power consumption less than 20 watts or so I5 to I7 sort of performance, 6th/7th generation? Larger SSD, e.g. 512Mb, though 240Gb would probably be enough. Prefer wholly Intel hardware/chipset, especially the graphics, to be sure it works well for Linux. Space for several hard disk drives, so a laptop isn't going to work, and anyway I want a big screen (currently 24"). Any ideas and suggestions? -- Chris Green

Hibernate Thinkpad
by steve-ALUG＠hst.me.uk 09 Nov '19

09 Nov '19

Howdy I brought a 2nd hand Thinkpad T430 & I've tweaked it so that Hibernate appears on the shutdown menu. In a command prompt, the command sudo pm-hibernate writes to disk and shuts down. Switching on brings the machine back to the state it was in on shutdown. Launching Hibernate from the startup menu, or from a command prompt typing sudo systemctl hibernate both write to the disk and shutdown, but on boot up, they start a fresh session, as if starting up from scratch. Anyone got any ideas how to successfully hibernate from the shutdown menu? Steve

Amateur Web Admin needs help!
by Phil Thane 27 Oct '19

27 Oct '19

Hi, I have an old PC out in the shed running (L)Ubuntu that I use as a Nextcloud server (also Cherry Music and wife's backup, but it's Nextcloud that is vexing me). A few days ago my phone flashed a 'can't connect' warning from the calendar sync, so obviously I ignored it for a while. Then I tried connecting from my desktop Nextcloud client, and that failed too. I did some basic diagnostics and found: 1. Nextcloud is running, I can log in fine from the desktop using the LAN IP address of the server. 2. I use DDNS to route WAN connections and that's working fine because when I try to use Firefox to access the server I get a 401 error from Nginx. (What I should get is a Nextcloud login screen). 3. That's odd because as far as I was aware the server ran Apache. 4. Issuing status commands to Apache or Nginx doesn't get me anywhere. 5. sudo apt install apache2 reveals that I already have the latest. 6. sudo apt install nginx gives me a list of packages to install (I didn't) so I assume that means I was right about having Apache not Nginx. But that doesn't explain the Nginx 401. 7. sudo ps ux doesn't show Apache running. 8. Trying to start Apache doesn't work: phil@webserver:/$ sudo service apache2 start Job for apache2.service failed because the control process exited with error code. See "systemctl status apache2.service" and "journalctl -xe" for details. That would be fine if I had any clue where to look for those log files. And was likely to understand what they say. So what I need (I think) is an idiot's guide to getting Apache running again that's easier than re-installing everything from scratch. Can anyone help? -- Phil Thane www.pthane.co.uk Tweet @pthane 01767 449759 07582 750607

Where have all the files gone?
by Bev Nicolson 08 Oct '19

08 Oct '19

I use Mint and having upgraded a small file yesterday (of course I recall what, d'oh) I have lost some files and folders on my desktop, though the right boxes are checked to show them. They haven't reappeared so far. How do I get them back? I'm not sure how to find out exactly which version of Mint I'm using. Tessa, certainly. Bev.

Seedbox vs VPS for linux VPS usage.
by John Cohen 08 Oct '19

08 Oct '19

I have a home server that's now a few years old, used for a mix of large file backups (16tb raid10), file serving and sharing (nextcloud/sftp) and a few other less important applications for personal use like rss reader, music streaming etc. I'm thinking of decommissioning it soon and moving most of its use to the cloud. Unfortunately cloud storage is still very expensive when handling audio/video files so I'm planning on creating backups locally and leaving the cloud storage (around 1-2tb) for mainly file sharing as well as my other various applications. I've already got 2 vps with digitalocean and am pretty happy with them, except for the storage price (astronomical if I wanted to add 1000GB storage to the droplets), so I've been hunting around for reliable and affordable servers that are also secure. This got me to looking at 'dedicated' seedboxes as an alternative to regular VPS. The prices for storage are staggeringly smaller. When including full root access, these start to sound very much like a traditional VPS, so I'm now wondering: 1) What's the real difference if most VPS machines out there are not truly dedicated machines- (really virtualised) but have everything you'd expect from root-access to dedicated ip address, ram and cpu usage, the same as a good seedbox? (example here of a seedbox with root access and 'machine' specs: https://www.rapidseedbox.com/#pricing) 2) Are there any inherent security downsides with a seedbox vs a traditional vps? My initial feelings are it's the same, as long as you personally secure the server thoroughly and the level of control (say root access, firewall, other typical linux security tweaks, file encryption done by myself on the server etc) 3) Seedboxes are mainly meant for fast torrenting (something I'm not interested in). So long-term reliability probably isn't their main concern when running the business, comparing it to a company offering VPS renting. Is this a fair assessment? Do seedboxes tend to be available in the long term, or is it more likely to cause me problems a couple of years along the line? (I'd obviously look for a company that's been out there for a while, but is it likely the servers reliability is not as good?) 4) Any thoughts of what else I could look into? Ideally in the 1-5tb storage range, but possibly less than £20 p/m. John
