| mapps | afternoon | 15:21 |
| Azelphur | can anyone explain how this works? http://pastebin.com/mVFLutDg | 15:28 |
| Azelphur | according to du, I've got like 40GB used, not 250. | 15:28 |
| * penguin42 looks | 15:33 | |
| penguin42 | Azelphur: under where? | 15:34 |
| Azelphur | what do you mean under where? | 15:34 |
| penguin42 | oh I see | 15:34 |
| penguin42 | Azelphur: So your /media is a separate 2TB mount? | 15:34 |
| Azelphur | yea | 15:34 |
| penguin42 | Azelphur: OK, so there are a few reasons that can happen | 15:35 |
| ali1234 | i too do not understand the question | 15:35 |
| penguin42 | Azelphur: One reason is that you might have some stuff in /media on the main drive that's hidden by the mount | 15:35 |
| Azelphur | ali1234: I'm trying to find out where all my drive space has gone, du is being less than helpful | 15:35 |
| penguin42 | Azelphur: So try umounting /media and duing it | 15:35 |
| ali1234 | use ncdu not du | 15:36 |
| ali1234 | du sucks | 15:36 |
| penguin42 | Azelphur: Similarly for /tmp or the like that's a shmfs mount | 15:36 |
| Azelphur | penguin42: that was the correct answer, looks like it hasn't mounted my second drive for some reason and is instead writing backups onto the tiny 250GB drive. | 15:36 |
| Azelphur | there we go, now things are much happier. | 15:37 |
| Azelphur | thanks :) | 15:39 |
| Azelphur | ali1234: btw, did you see my silly lights video? :) | 15:40 |
| ali1234 | yes | 15:40 |
| Azelphur | hehe | 15:40 |
| ali1234 | looks like a good way to get rid of unwanted house guests | 15:40 |
| Azelphur | that's true, it'd probably be remarkably effective | 15:40 |
| Azelphur | especially if I played country music instead | 15:40 |
| ali1234 | why do you have windows that go to the floor? | 15:41 |
| Azelphur | ali1234: the building is circa 1700s and is protected | 15:42 |
| mapps | hmm | 15:48 |
| mapps | my raspberrypi stopped working again..yet was plugged in and net up..anyopne got any ideas what could be causing it?! | 15:48 |
| penguin42 | mapps: I'd try adding some warm custard | 15:53 |
| mapps | :D | 15:56 |
| DJones | \o/ New drive installed & setup, just copying data off the old drive now | 16:00 |
| penguin42 | mapps: So without knowing the Pi specifically; 1) Check your SD card, they're made of cheese, 2) Check how you're powering it | 16:06 |
| mapps | pah:P i cant im not there..so just check sd and cables afaik all fine | 16:09 |
| mapps | where would it log any errors to that could cause it to die dmesg? | 16:09 |
| penguin42 | mapps: Well yes but that depends why it died, if it couldn't get to the SD for example then they won;t have been able to get recorded onto the said SD | 16:11 |
| penguin42 | mapps: If it does it regularly then try and setup network or serial logging to another machine | 16:13 |
| mapps | its done it after a week of 24/7 | 16:17 |
| mapps | my dad unplugged it and plugged back in it boots up and all works fine agao | 16:20 |
| mapps | if it runs out of memory..too much running would that d oit? | 16:21 |
| penguin42 | mapps: The other thing then to look for is how dead it is - does it still ping for example? Also look if there is support for any watchdog timer on it so it can reset itself | 16:21 |
| penguin42 | mapps: If you've got a leak somewhere then yes | 16:21 |
| mapps | couldnt ssh to it/reach apache or vpn didnt try pinging | 16:21 |
| penguin42 | mapps: ping first :-) | 16:21 |
| mapps | watchdog timer?! surely there wouldnt be anythong to reset after x days if thats what you mean?! | 16:22 |
| penguin42 | mapps: The idea with a watchdog is that it's a timer that you have to prod every few seconds, if you don't it sends a reset | 16:22 |
| mapps | ah | 16:23 |
| penguin42 | mapps: Then you get something that just checks everything is ok, and prods the timer; if anything breaks it resets | 16:23 |
| mapps | as it assumes somethings gone wrong| | 16:23 |
| mapps | ya | 16:23 |
| penguin42 | yep | 16:23 |
| mapps | if it was rebooting it would be fine..eveything comes back to lie..apache..vpn..iptables rules etc | 16:23 |
| mapps | but it just crashes/hangs from what i know..im not there..dad says its on..i cant reach it minute he unplugs and plugs back in works again;( | 16:24 |
| penguin42 | mapps: The other thing you can do is do things like write a program that just continously flashes an LED (I assume it has one you can do that to) - and when you invoke your dad to kick it, he can tell you if the LED is still flashing | 16:26 |

| shauno | there's a fun task for an arduino there .. a hardware watchdog. that if it hasn't had a 'blink' for long enough it powercycles | 17:50 |
| penguin42 | shauno: You don't need an arduino for that; I think you can do it with transistor+capacitor type of thing | 17:53 |
| penguin42 | shauno: Or relay+cap | 17:53 |
| shauno | well yeah. but arduinos are like Pis .. I have more than I'd like to admit :) | 17:55 |
| shauno | (and can evolve pretty easily .. eg to provide a soft-off) | 17:56 |
| shauno | I have a troubling amount of these knocking around .. http://oomlout.co.uk/collections/arduino/products/arduino-component-bundle-arcb | 17:59 |
| penguin42 | shauno: Oh that's quite a nice little set | 17:59 |
| shauno | a couple of quid more than it needs to be, but I'm lazy | 18:00 |
| penguin42 | yeh, I was thinking it's a bit more pricey than shrimpit | 18:01 |
| === Lcawte|Away is now known as Lcawte | ||
| mapps | lol penguin42 re kicking it:D would be nice to know why it does it though | 18:59 |
| penguin42 | mapps: Right, but that's what your serial or network console type things help with if you can't get anything from the logs | 19:27 |
| mapps | not sure what you mean by serial or network console..and on a pi?? | 19:34 |
| camason | Evening. I need to setup OpenVPN on a server in a remote office, but that's going to involve fiddling with network | 19:38 |
| camason | what's the safest way to adjust settings? Any way I can do it and not lock myself out? | 19:38 |
| ali1234 | is there a way make it so that malloc will never reuse a virtual address? (other than never freeing memory at all) | 19:44 |
| ali1234 | with a 64 bit address space this should be at least feasible | 19:45 |
| penguin42 | camason: Give yourself another way in | 19:45 |
| penguin42 | camason: setup two vpn setups, only ever work on one at a time | 19:46 |
| camason | penguin42 it's more I need to re-jig my eth settings, and I fear one mistake will take the network offline | 19:46 |
| penguin42 | ali1234: See man mallopt - but I don't think anything like that lets you do it | 19:47 |
| penguin42 | camason: Trust me, it will :-) | 19:48 |
| penguin42 | camason: Some type of watchdog where you arm the system to reboot itself/put it's self back to a good state is what you need then arm that before you make any change - if you really only have one way in | 19:49 |
| camason | yes I was thinking perhaps a script that will execute after 5 mins, replacing /etc/network/interfaces with a known working config, then restarting it | 19:50 |
| penguin42 | camason: It is of course difficult to anticipate how you might screw it up | 19:51 |
| camason | yup! | 19:51 |
| camason | there are a myriad of ways when I'm involved :) | 19:51 |
| penguin42 | camason: Humans are creative | 19:52 |
| penguin42 | camason: Doing things like holding your config files is a good way to be able to roll back; but automating that I've not seen | 19:52 |
| penguin42 | ^your config files in git.... | 19:52 |
| camason | reminds me of a line from The Thick Of It... that I could't replicate here for reasons of taste. | 19:52 |
| ali1234 | is it possible to tell valgrind i only care about memory referenced from a single source file? | 19:54 |
| penguin42 | ali1234: I know it has ways of marking areas of code, I'm not sure by source file | 19:55 |
| mapps | penguin42, what did yoiu mean by serial or network console | 20:05 |
| penguin42 | mapps: You can configure syslog to send all messages to another host, similarly you can configure the kernel to send console messages to another host; so if the SD card stops or a lot of other stuff fails you still see the messages | 20:06 |
| penguin42 | mapps: Similarly for a rs232/serial console | 20:06 |
| mapps | i dont get it..so how can i do this on the pi | 20:08 |
| mapps | 'network console'?:! | 20:09 |
| penguin42 | mapps: Is the pi the only machine there or is there another linux machine within spitting distance? | 20:12 |
| mapps | ther'es another machine a dell desktop running Linux that i could getr my dad to turn on | 20:13 |
| mapps | but can you explain what you mean when you say network console that i cant grasp..i know what the console is;p | 20:13 |
| penguin42 | mapps: Every piece of text that's output to the console gets sent over the network so that it can be logged | 20:14 |
| mapps | aha | 20:14 |
| mapps | surely errors and that wouldnt tho ..dont see them on console if they go to a log | 20:15 |
| penguin42 | mapps: Well it depends why it's dieing, if you're getting a kernel panic, some types of kernel panic will get to the console and over the network, some won't | 20:16 |
| mapps | so if i jhad a console up and was logged in locally with as GUI kernel panics would show in that terminal? | 20:17 |
| mapps | just be handy to find out so can fix it | 20:17 |
| mapps | i want it running 24/7 and noones gonna be there most the time | 20:17 |
| penguin42 | mapps: Best not to have the GUI running, and best to turn the screen blanking off with setterm, but yes | 20:17 |
| mapps | thanks | 20:18 |
| penguin42 | mapps: So you can ask someone just to turn a monitor on and take a picture of it before they powercycle it | 20:18 |
| mapps | yea | 20:18 |
| mapps | or network console could be a good idea? | 20:18 |
| mapps | but if i cant reach the pi ..surely its networks down so it wouldnt be able to reach the other machine? | 20:19 |
| penguin42 | well that depends how it died | 20:19 |
| penguin42 | mapps: Serial consoles are more primitive, they tend to be able to send things with almost everything else gone | 20:19 |
| mapps | so network could still unction but apache/vpn dead? | 20:19 |
| mapps | yea | 20:19 |
| mapps | cant access it locally tho;) | 20:20 |
| penguin42 | that's why you need another pi to monitor the first pi.... | 20:20 |
| mapps | for network console? ..i could do that with the dell linux machine | 20:20 |
| penguin42 | yes you could | 20:20 |
| penguin42 | mapps: See https://www.kernel.org/doc/Documentation/networking/netconsole.txt | 20:21 |
| mapps | thanks | 20:21 |
| mapps | could it be as simple as i have too much running on it? vpn/apache/ftpd /mrtg ? | 20:26 |
| penguin42 | if you're running out of memory, possibly, but it's unlucky to kill everything | 20:27 |
| mapps | £6.40 or a lite of stolichynia | 21:40 |
| mapps | :D | 21:40 |
| mapps | bargain | 21:40 |
| penguin42 | doesn't drink or smoke; what's the good chocolate like... | 21:51 |
| mapps | i smoke more now im here | 21:53 |
| mapps | as foolish as that is | 21:53 |
