nut upsmon comms issues
by Mark Rogers 14 Nov '16

14 Nov '16

Anyone here got more experience of UPS monitoring than I have? I have a UPS configured and working, however it periodically loses communications. I'm not too concerned about that - the server is due for replacement in the next couple of months anyway - but the comms errors are generating emails that I'd like to tweak so they're not filling my inbox. My inbox is filled with COMMBAD emails, followed within seconds (under a minute, usually) by COMMOK. So I'd like to put a delay on the triggering of a warning. The parameter that looks right is NOCOMMWARNTIME in /etc/upsmon.conf, but it defaults to 300s (5 min) anyway; I upped it to 600s (10min) with no change. I think on re-reading the man pages that this affects how often the warning is sent once triggered, not how long after detection the first warning gets sent. The emails get sent to a dedicated "systems" mailbox that should only get stuff that needs action, so getting a COMMBAD/COMMOK pair every few hours is quite frustrating. But turning off monitoring altogether seems like a bad "fix".

ALUG Announce Please send announcements to Announce(a)lists.alug.org.uk Unsub, change settings via https://lists.alug.org.uk/mailman/listinfo/announce ----- Hello Norwich Aluggers, Our monthly ALUG Norwich social meeting will be held this Thursday, 10th November at The Coach and Horses (82 Thorpe Road, Norwich, NR1 1BA). The meeting officially starts at 8pm, although some people may arrive earlier. More information on those people can be found on the list and the IRC channel. If you are unsure if you will recognise us then make yourself and your intent to attend known by either posting on list or visiting us on IRC so we can look out for you rather than hiding in the corner. Optionally you could ask at the bar if they know where the geeky computer weirdos are and they'll point you in the right direction (seriously!). Another possibility is look for heaps of electronics on a table that may possibly look like movie props that would used for detonating explosives. Feel free to bring electronics/laptops/gadgets to the meet, you will by no means be alone. Ben Bewick aka Viperfang NB: This mail is automated, please refer to the usual sources for more information.

Re: [ALUG] Building an (air gapped) offline Linux laptop as a newbie toLinux
by Noel Galer 03 Nov '16

Ian, >From another noobie, may I wish you every success with this interesting project and I look forward to hearing of your progress. Best regards, Noel ( Xorsyst ) ________________________________ From: main [mailto:main-bounces@lists.alug.org.uk] On Behalf Of Ian Henderson Sent: Wednesday, November 02, 2016 9:09 AM To: main(a)lists.alug.org.uk Subject: [ALUG] Building an (air gapped) offline Linux laptop as a newbie toLinux Hi, all, I am new to Linux. I'm porting over to Ubuntu 16.04 LTS with the Unity desktop from Windows 10. I want to keep things as simple (and hopefully therefore as reliable) as possible, for home/office critical use. I also want to stick to the main and universe repositories. Because prices were much lower for Linux-compatible laptops than with Win 10 installed, I can afford two. I plan to divide them into one for critical offline-only use, and the other for universal online use. I will air-gap the two. But it also means that I need to complete the final build of the offline air-gapped laptop ahead of porting data, after which it will not go online again (unless for a wipe and rebuild). For the offline-only laptop, I am looking at the following range of apps. Could I ask that you check my ideas, and offer suggestions and advice, please.:- 1) An office-like suite, for which I will be using LibreOffice, which is installed by default. 2) I need a whole-directory and free space overwriting utility, as well as the means to securely delete individual files. My understanding is that shred and wipe are available by default. I am looking at bleachbit for the whole-directory and free space wiping. But the software centre says "sudo" for this app: does that mean it has elevated privileges and is this a bad idea? 3) GtkHash for SHA256 etc. cryptographic hashes, primarily to verify backups. 4) Can anyone suggest an archiving utility which also verifies the files within the archive (I can then hash the archive file backup)? Archiving does not necessarily have to include compression. Are any installed by default? 5) GnuPG. I understand that this is installed by default? Am I correct that I can encrypt with password files if transferring on FAT32 USB or CD/DVD with this? Is it GUI? 6) CD/DVD burning, including both copying using a single optical drive, ordinary file burning and creating bootable CD/DVD from ISO images. I'm looking at Brasero for this. Can anyone suggest any other apps I should include ahead of locking off the build? I'm also assuming that the default 16.04 LTS supports formatting USB sticks to ext4, including encryption? Also, anyone any thoughts on using live-CD version of Ubuntu for online banking (in case the online unit got owned)? Please remember that I am a complete newbie to Linux. So please remember if you start talking about OpenWTF 0.666.1066 I will have no idea what you're talking about! Not for some months yet, anyway. :) Thanks for your help, Ian (C) Copyright 2016 by Ian Henderson. All rights reserved.

Is there such a thing as an ethernet switch with WiFi?
by Chris Green 31 Oct '16

31 Oct '16

This isn't really specifically a Linux question but I'm sure the ALUG team should be able to come up with an answer. I want a box which is an ethernet switch/hub (ideally an 8-port though five might be just enough) and also provides WiFi. I.e. a switch with both wired and wifi connections. It doesn't have to have any other intelligence, it doesn't need to be a router or anything. This is to hang onto the ethernet port of an outdoor WiFi access point which is running in WISP Client mode (a TP-Link TL-WA7210). The TL-WA7210 provides DHCP and DNS (via the WiFi hotspot it's connected to) so all I want is a box to provide multiple wired and wifi connections to the LAN side of the TL-WA7210. Is there such a beast? Is there a specific name for it? -- Chris Green

iplayer issues
by Chris Walker 31 Oct '16

31 Oct '16

I recently built myself an HP ProLiant server. It's running Ubuntu server and I have most things working except the get_iplayer PVR option. I can run get_iplayer as the user as I have a script on the box which runs and can set the output correctly and transcode it into the required formats (radio and tv). So everything *appears* to run ok. But when I add the pvr option, I don't get the required downloads. Just in case it was something I'd done on the server, I tried creating a pvr list on this machine with just one radio programme, but again, when I run the pvr command, I don't get any downloads, only the statement that it's 'Running PVR Searches:'. Has anybody any idea where I'm going wrong please as I've spent many hours on this now and I'm getting nowhere despite looking through several pages of FAQ on the get_iplayer forums. -- __ __| |_ __ __ .----------------------------------------------. / _/ _` \ V V / | mailto:alug_cdw@the-walker-household.co.uk | \__\__,_|\_/\_/ |______________________________________________|

SETI etc
by Mark Rogers 27 Oct '16

27 Oct '16

I have a virtual server at a hosting provider that I've cancelled, but it's got a few weeks left of what's currently been paid so rather than just leave it switched off I wondered about using it for something like SETI or similar. I really don't have time to configure and play with something; it really wants to be as close to "apt-get install seti" and walk away as I can get. It's also worth bearing in mind that this isn't a high power VM and I don't want to do anything that will upset the hosting provider by overstressing it. Suggestions? Or should I just leave it to fester? Mark -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) 21 Drakes Mews, Milton Keynes, MK8 0ER
