[08:22] <DrManhattan> Hello, I'm running 18.04 server on a laptop with no GUI and I'm hoping to poweroff the screen when there's no input. Google is not yielding me good results. The screen stays on. Can anyone here help?
[08:37] <blackflow> DrManhattan: look up "consoleblank" parameter
[08:38] <DrManhattan> I tried that, it didn't work
[08:39] <blackflow> DrManhattan: how about "setterm"?
[08:40] <DrManhattan> that has no effect either - "setterm --powerdown 1" did nothing, either locally or via ssh
[08:40] <blackflow> so then what do you mean by "poweroff the screen"? you mean literally turn its power off?
[08:41] <blackflow> oh wait, laptop.... nvm.
[08:41] <DrManhattan> if I had a GUI installed it's a piece of cake :)
[08:41] <blackflow> well, if consoleblank kernel parm, or setterm don't work, I don't know what else is there.
[08:41] <DrManhattan> now I just get my feeling hurt
[08:41] <DrManhattan> Ok, thank you. I'm just going to call this one a lost cause
[08:42] <blackflow> DrManhattan: you could always run a dummy xorg if that really bothers you :)
[08:43] <DrManhattan> :/
[08:44] <blackflow> well I'm not really kidding. you could run just xorg, no DE or anything, to get the advantage of gpu modes and xset command.
[08:44] <blackflow> ... _if_ that really bothers you. alternatively I'd look into your specific laptop model and if there's a way via acpi(d)
[08:44] <DrManhattan> Yeah I know, but I'll just use the fn+f9 feature of the laptop and turn the monitor off manually
[08:45] <DrManhattan> I appreciate your help
[08:46] <blackflow> that actually ain't bad idea at all. minimize console time (admin it via ssh) and it'll probably stay off most if not all the time.
[08:46] <blackflow> (as in you won't need to remember to turn it off when you walk away, often)
[08:47] <blackflow> ansible-playbook -l dev -t zfs_part
[08:47] <blackflow> oops, sorry, wrong window

[09:07] <DrManhattan> I could remove the monitor entirely too, and just hook a VGA one to it if needed
[09:07] <DrManhattan> it's nothing more than a plex transcoder anyhow
[13:26] <petrhl> hi
[13:26] <petrhl> I'm trying to set Hurrincane electric tunnel. It works on a server, clients get ipv6 address but pinn6 to google com doesn't work. I've been googling for over an hour but still don't know what I did wrong. Could you help me please? Here is list of radvd.conf, iptables etc. https://pastebin.com/bVyW15wS Thanks!
[13:42] <RoyK> petrhl: pastebin output of 'ip -6 route'
[13:57] <pragmaticenigma> I'm interested in finding a tutorial/instructions for setting up a machine that can auto-decrypt an encrypted drive on boot. The key or keyfile would live on a different machine that the encrypted machine would fetch from.
[14:00] <pragmaticenigma> I've seen the dropbear method, but that appears to require user intervention. My hope is to have a keyfile served by a raspberry-pi or something similar on the local network

[19:35] <caliculk> Hm, ran into another samba bug that tends to point out that it requires zfsacl: https://bugzilla.samba.org/show_bug.cgi?id=13242 ahasenack I am beginning to think that it would be a good idea to implement, but, still looking at it. :(

[23:19] <Sven_vB> hi! according to htop, my VPS is mostly idle – almost no CPU or memory use, load average below 10%, "Tasks: 381, 27 thr; 1 running", but somehow it experiences lots of lots of "postfix/smtpd[21555]: fatal: socket: No buffer space available" and "bash: fork: Cannot allocate memory". how to debug?
[23:20] <leftyfb> Sven_vB: Ubuntu version, hardware specs, configs and purpose of the server please
[23:22] <Sven_vB> Ubuntu 14.04.5 LTS trusty, lowest tier HostEurope virtual server, which configs?, hosts my website and mail.
[23:26] <teward> Sven_vB: 'lowest tier' means nothing, if you state us the specifics of that tier that might help
[23:26] <teward> such as what specs you are actually assigned - RAM, number of CPUs, etc. - that'd be more helpful
[23:29] <leftyfb> Sven_vB: being a virtual server, sounds like your host might be throttling your VPS when it tries to do too much. You REALLY should contact them when this happens to see if they can see anything on their end
[23:29] <Sven_vB> oh ok. 1 vCPU (single) core, 4 GB RAM + 3 GB swap
[23:30] <Sven_vB> I've contacted them the last few times it happened, but they couldn't see any anomalies from the outside.
[23:31] <leftyfb> Sven_vB: maybe time to get bare metal or separate VPS's for each of your services. Or spend a ton of time optimizing the hell out of your services/code/OS
[23:32] <Sven_vB> you mean it's actually overloaded even though htop shows it as almost idle?
[23:33] <teward> it can be
[23:33] <teward> Websites can take up a lot of resource
[23:33] <teward> mail can too]
[23:33] <teward> depending on what you're running, etc.
[23:34] <teward> how are you determining CPU and memory use?
[23:34] <Sven_vB> I'll shutdown apache and postfix and see if it gets better then
[23:34] <Sven_vB> teward, the "uptime" command and the bars in "htop"
[23:34] <teward> use `free -m` to check your memory usage
[23:34] <teward> htop sometimes doesn't report data in a useful way
[23:35] <Sven_vB> free -m: https://paste.ubuntu.com/p/Fptrkx433D/
[23:36] <Sven_vB> teward, also I'm planning on monitoring some values from /proc/meminfo. which ones would be important? I guess Buffers Cached HighFree and LowFree?
