| if I have the arp VPN, do I still need to use ssh to tunnel vnc? | [11:39] | |
| apparently yes still
And ugh! the FreeBSD DVDs arp provides don't have a fixit shell! they're "disc1". I'll have to figure out what should be mounted instead. | [11:53] | |
| got it. need the dvd1 release, not the disc1 release. :(
support@ request made. hopefully filled soon because otherwise all our machines are at risk if they ever fail to boot. | [12:07] | |

| mike-burns | Tarsnap for data, git (and the rcm suite of programs) for dotfiles. But then my git repos are backed up with tarsnap. | [12:50] |
| ..... (idle for 20mn) | ||
| plett | Most of the stuff I want to keep backups of in git and i push to a remote repo when i make changes, but I also use duplicity for backing up home dirs
I don't do whole machine backups any more. I can re-build a machine from an OS installation and either ansible or puppet | [13:10] |
| brycec | Yeah, it's pretty pointless to backup /bin, /usr, etc. Just a waste of space. | [13:14] |
| mnathani_ | can a raspberry pi be used to control the power (on/off) of a power bar
Ideally, I would like to connect to the pi over network and toggle the switch | [13:23] |
| brycec | In short, yes.
On its own, no. But can you toggle an opto-relay from a GPIO? Of course. It's widely documented. | [13:31] |
| *** | poulsen has joined #arpnetworks | [13:38] |
| m0unds | i use crashplan to backup desktop & notebook computers to my nas and to teh klaud. i rsync data from my remote servers to my nas, which also gets backed up to teh klaud
i have some old stuff that i need to keep encrypted and stored in glacier, and some critical stuff encrypted and stored on s3 as well. photos get backed up to the nas -> crashplan and also to smugmug | [13:38] |
| mnathani_ | would you recommend another solution for IP based power toggle? | [13:42] |
| m0unds | tripplite makes some decent managed power stuff
their isobar surge protection stuff is really good and less expensive than some alternatives triggering a relay via gpio on an rpi sounds like a fun project (i've done similar to control a fermenter) | [13:43] |
| brycec | mnathani_: There are probably cheaper ready-made stuff. Eg. Belkin's line of WeMo stuff. | [13:45] |
| m0unds | yeah, mfi by ubiquiti has some power products too, iirc | [13:45] |
| brycec | (depending on how "professional" you're looking) | [13:45] |
| m0unds | https://www.ubnt.com/products/#all/controlautomation
my buddy used mfi stuff and a home built fan box to control the aerator on his septic tank | [13:46] |
| mnathani_ | brycec: nothing too fancy, just needs to have IP connectivity
or an app I guess | [13:47] |
| brycec | http://www.amazon.com/WeMo-Electronics-Anywhere-Automation-Smartphones/dp/B00BB2MMNE/ $43 USD for what it's worth, wifi, app, ifttt.com integration, etc. | [13:52] |
| BryceBot | Amazon: "Belkin WeMo Switch, Control Your Electronics From Anywhere with the Home Automation App for Smartphones and Tablets, Wi-Fi Enabled" | [13:52] |
| brycec | May or may not be the fanciest one or cheapest, but it is aimed to be easy and the like.
(I have 0 experience with any consumer remote power switch, for the record) Apparently http://www.amazon.com/WeMo-Electronics-Anywhere-Automation-Smartphones/dp/B00EOEDJ9W/ $53USD can also monitor usage | [13:52] |
| BryceBot | Amazon: "Belkin WeMo Insight Switch, Control Your Electronics and Monitor Energy Usage From Anywhere with the Home Automation App for Smartphones and Tablets, Wi-Fi Enabled" | [13:53] |
| mnathani_ | great
ordered from Amazon | [13:54] |
| brycec | Cool, good luck :) | [13:55] |
| mnathani_ | brycec: Thanks | [13:55] |
| brycec | mnathani_: Out of curiosity, what are you controlling?
In my life, I've never seen a need for a remotely controlled power outlet So I'm curious what need you found. | [13:55] |
| mnathani_ | I have some cisco equipment in my room, hooked up to a single power bar
its for my home lab I can access it remotely once its on but it needs to be manually powered on at this point | [13:57] |
| brycec | And you need to remotely power-toggle it? | [13:57] |
| mnathani_ | yes, since it will be accessed remotely
that or, get someone at home to switch it on | [13:57] |
| brycec | Ah. You said "home" and I sorta assumed that meant you would be at home with it :p
And leaving it on all the time would obviously be wasteful. | [13:58] |
| mnathani_ | loud more than anything else | [14:00] |
| brycec | If you're not home to hear it... | [14:01] |
| mnathani_ | being considerate to other residents of the household, I guess :-) | [14:02] |
| mercutio | i can understand not wanting to have that kind of stuff on at home
while you're home. what i don't understand is why "server" gear automatically seems to mean not having fan speed adjustment etc in some gear 1u servers are always going to be a little hard to have quiet | [14:07] |
| brycec | "server" usually means assuming that noise/volume is not an issue. Then you realize you can remove a component that may potentially fail, a fan controller or speed logic, and just let the fan run at full speed.
At least, that was our logic when I worked for a company that built servers. Except the motherboard still had a fan controller anyways and we used that | [14:10] |
| m0unds | PWM controller or whatever? | [14:12] |
| mercutio | when i was looking at infiniband switches you can get them "kind of cheap" but "EXTREMELEY NOISY"
and someone said about doing replacements with noctura making a huge difference | [14:12] |
| brycec | m0unds: yeah the onboard 3- and 4-pin headers :p | [14:12] |
| mercutio | brycec: i have to use ear plugs in "server rooms" | [14:13] |
| m0unds | i had a headset i would wear if i had to work in the server room for more than a minute or so | [14:13] |
| brycec | ^ OSHA guidelines dictate the same for any non-brief time spent. | [14:13] |
| mercutio | if people cared a little more about noise maybe that woldn't be the case | [14:13] |
| m0unds | shooting muffs, kept them in my bag because my employer refused to furnish them | [14:13] |
| mercutio | heh | [14:13] |
| m0unds | now they're in my truck in case i forget to throw my nicer ones in my bag when i go shooting, haha | [14:14] |
| brycec | We definitely didn't really care about noise complaints. The fact that people would buy them and put them under the receptionist's desk was on them. They bought a "server" and should treat it as such, dammit. | [14:14] |
| mercutio | brycec: yeh different people have different ideas about servers
and switches switches can be noisier than servers | [14:14] |
| m0unds | i think people unfamiliar with that stuff just assume it's like desktop computers on wire racks in a room somewhere | [14:15] |
| mercutio | buut it's because they do 6000+ rpm on the fans contsntaly often :/ | [14:15] |
| brycec | m0unds: And some are :p (eg MacMiniColo.net) | [14:15] |
| m0unds | and don't realize how unholy loud it can be w/switchgear, servers, etc all running in a confined space w/air handlers and other shit running | [14:15] |
| mercutio | well there's extra power use from higher fan speeds too | [14:15] |
| m0unds | right
frontrangehosting up in denver did it too and there's some other colo company that does it | [14:15] |
| brycec | Extraordinarily minimal difference in power usage on those small fans. | [14:16] |
| mercutio | i think doubule temperature control would be cool
like "internal" temperature control and "external tempeature control but extenral being fed from IP oir such | [14:16] |
| brycec | ^ Many motherboards can sense inlet and outlet temperature | [14:16] |
| mercutio | because if you're running at 60c
but the room temp is 40c running higher fan speeds probably won't even make much diff brycec: yeah but it may be too "close" | [14:16] |
| m0unds | ehh, it was alright on microATX formfactor stuff w/ivy bridge intel cpus on it - you tell the BIOS how you have the fans set up and it bases fan speed on that
did a reasonable job w/those boards (intel boards, 3700 cpus) despite them being tiny and the enclosures being tiny supplement it w/some sane minimum fan speeds if it's not doing what you want and it works out reasonably well | [14:17] |
| mercutio | at 40c the cooling in the server room has probably failed, everything tries to save itself :)
which will increase power draw. | [14:21] |
| m0unds | power draw isn't a big concern if cooling failed, getting cooling working again is, haha | [14:22] |
| mercutio | yeh it is
but failuure time can be pretty short... power draw increases heat. even if servers are idle | [14:22] |
| m0unds | sure | [14:23] |
| mercutio | but even buying a few minutes would be a good thing | [14:24] |
| m0unds | that's why backup cooling exists
i'd rather not grenade hardware for no reason | [14:24] |
| mercutio | m0unds: yeh sometimes backup can fail at the same time | [14:24] |
| m0unds | deal with that if it's the case | [14:24] |
| mercutio | i don't know how common it is, i was reading about failures when i was reading about server room temperatures.
you should deal with that, but if you get 45 minutes instead of 40 minutes it makes it easier to deal with that. i think the usual "solution" is to turn off some people http://www.datacenterknowledge.com/archives/2015/01/06/heatwave-cooling-failure-bring-iinet-data-center-down-in-perth/ like that's one example from what i understand that article minimises the failures that users experienced, and lots of users couldn't authenticate etc. | [14:25] |
| m0unds | well, that sounds like multiple primary cooling failures | [14:28] |
| mercutio | yeh | [14:28] |
| m0unds | if they added "backup cooling" as a future solution | [14:28] |
| mercutio | but collobrative cooling would improve things a little. | [14:28] |
| m0unds | i saw iinet and thought of infinity internet up in portland (now easystreet)
had a couple friends who worked there | [14:29] |
| mercutio | iinet is a huge provider in australia i think
it'd probably be like verizon or somethign in the US | [14:29] |
| m0unds | yea, different company. just saw the name in the url and thought of infinity | [14:29] |
| mercutio | i'm curious what'll happen with electronics power draw decreasing.
here adsl/vdsl cabinets all have cooling. i don't know how redundant they are, but that kind of area may be a better place to start. | [14:31] |
| m0unds | same here, also catv equipment cabinets | [14:32] |
| mercutio | as you can hear the cabinets :/ | [14:32] |
| m0unds | pretty loud too | [14:32] |
| mercutio | they always get grafitti on them.
so there was some initiative to put artwork on them. | [14:32] |

so motherboard doesn't like new cpus :/ have to put old cpu in to do bios update the only "new" cpu i have is in my server err new old it's haswell vs haswell refresh | [18:40] | |

| mercutio | yeah kind of scary | [22:17] |
| mnathani_ | acf__ :do you have a link for that story? | [22:19] |
| mercutio | i seem to be stuck with samba doing twice as fast write speeds as reads :(
the other way around would be nicer. | [22:22] |
| brycec | Correct, no post/no boot. We couldn't tell anything. Wasn't until some back and forth with the vendor ("we're using this CPU" "be sure you're using bios version >X" "Of course we are, that's the version you're supposed to be flashing before shipping these" etc) | [22:23] |
| mercutio | did it have the bios version written on the motherboard?
i thought asus were meant to have nice bios's. it's worse than asrock :( even asrock z77 is better than the asus z87 | [22:24] |
| brycec | mercutio: As it happens it does have a sticker on the BIOS ROM, but it was coded (eg didn't simply read "V. 1.01")
Eventually we did notice the difference in stickers and it all made sense And all boiled down to them failing to include the BIOS they were supposed to (among other slight failures) And a great lesson was learned :p | [22:25] |
| mercutio | ahh
i had a motherboard rom failure and i had to get a new rom, and i noticed that my one mentioned the bios version fine. its' not acutally that hard to change the rom chip and they sent me a replacement rom they seem to socket them | [22:27] |
| brycec | Not many vendors seem to socket them these days
My desktop ASUS boards don't, my Intel boards don't... | [22:28] |
| mercutio | lots of them do dual bios
oh? well this was asrock it seems it may have been intel me getting corrupt | [22:28] |
| brycec | heh | [22:29] |
