jednoducha vec. uplne jednoducha, primitivna.
Pocitac (macbook) v stave sleep, k netu pripojeny cez wifi. Router nie je apple (a ani nikdy nebude). V ruke ipad.
A moja jednoduchucka, primitivna, az smiesna, az trapna otazka znie - ako remotne prebudim mac zo sleepu a pripojim sa nanho nasledne cez teamviewer. Vsade sa hovori o wake on lan, o kuzelnych paketoch, ale nikde som nenasiel podrobny postup krok za krokom pre lamy.

no, mne sa iMac zvykol sam od seba prebudzat, co bolo dost rusive najma v noci, az kym som nevypol wake on lan...

I used to be schizophrenic, but we’re OK now

ja som to vyriesil dvoma sposobmi (setup: mac mini sta server pre itunes, plex atd + ipad)

- na ipade mam app remote na ovladanie itunesu na macu - to ho vie zobudit
- takisto app mobile mouse to vie rovnako (ale na macu musis mat tiez nainstalovanu nejaku ich chujovinu)

cize nie je to idealny postup, ale lepsie som nevymyslel..

apple is apple, but strudel is strudel

0000010100063540000635420210967701857521071801560718674207186988

dikes, skusim aspon toto. Vidim, ze to nebude take jednoduche ako by to uz v roku 2013 malo byt

00000101000635400006354202109677018575210718015607180279

zabaval som sa s tym asi tyzden. nefunguje to :)
teda aspon mne sa to nepodarilo rozchodit.

ked bol mbp v sleepu kratko (par minut) tak mi to fungovalo, ale ked uz bol dlhsie tak sa nikdy neprebral.

0000010100063540000635420210967701857521071801560718027907180331

Ak v mbp (retina, takze bez ethernet karty) vymenim OS za linux alebo windows, podari sa mi to spojazdnit?
Alebo musim menit aj platformu?

wake on lan cez wifi je tak skurvena featura, ze to pravdepodobne nefunguje na takmer ziadnej kombinacii HW/OS/SW/AP

Where's you pope now?

00000101000635400006354202109677018575210718015607180279071803310718117407184955

ja som to robil tak, ze som sa sshckol na router (openwrt) a odtial som poslal po LAN magic packet.

jj, ale to silne zalezi od ACPI a samotnej wifi karty, resp. jej drivera, ci karta ostane pocuvat, alebo vypne radio. mne to s niektorymi kartami nefungovalo ani po kabli.

Where's you pope now?

ja som ale wake-oval ethernet:) myslel som to tak.Ako posles wol wifi karte? neviem si to predstavit technicky.

00000101000635400006354202109677018575210718015607180279071803310718117407184955071849580718497207185015

WoL na wifi sa asi riesi niekde este nizsie, pretoze zariadenie v spanku zrejme nebude zostavat asociovane. povedal by som, ze sa budu vysielat nejake obecne beacony s MAC adresou, alebo co. to je jediny sposob, ako by to mohlo fungovat bez toho, aby sa karta musela aktivne hlasit routeru a byt zasociovana. a asi prave preto to nahovno funguje.

ano, tie becaon framy ma napadli.Niekedy si to nastudujem, ako to je implementovane.Zatial som to nikdy nepotreboval.

00000101000635400006354202109677018575210718015607180279071803310718117407181182

no na apple HW + aitport AP v kombinacii s bonjour to funguje paradne.. ale kedze AP menit nechce tak neviem

000001010006354000063542021096770185752107180156071802790718033107181063

to netusim. skusal som to iba pod osx.

00000101000635400006354202109677018575210718015607180189

neskusal som, ale nasiel som toto:
https://discussions.apple.com/thread/3735289?start=0&tstart=0

"Here's what's going on: Apple changed the kernel's response to magic packets (the Ethernet WoL packet) so that, by default, the machine no longer wakes up fully when it recieves one; it stays in low-power wake. Instead, they want you to buy an AirPort or use another computer (a Bonjour Sleep Proxy) to watch the network for traffic trying to reach certain services on your sleeping machine, and to give it a kick (a WoL packet) when it sees such traffic. This kernel feature is called Dark Wake.

But that's annoying. Many things don't use mDNS, and many people aren't using Apple router products. I use SVN to sync things between my computers, so when my Mac Pro is asleep, I want to be able to wake it up from wherever I am and from whatever device/platform I'm using. So, I told the kernel not to use Dark Wake.

The kernel is the very first program that the boot loader (which is the first screen you see when you power on your computer -- probably grey and with an Apple logo) calls. The boot loader can pass arguments to it, much like other programs you might run from the command line.

Here's the procedure I used (please don't do this unless you're comfortable using vi to edit system files):

Opened a Terminal window.
Changed to /Library/Preferences/SystemConfiguration by typing the following: cd /Library/Preferences/SystemConfiguration
Edited com.apple.Boot.plist using vi under sudo (because the file is owned by root):
sudo vi com.apple.Boot.plist
Moved the insertion point down to the associated with the Kernel Flags
Hit the "i" key to begin inserting text
Typed darkwake=0
Hit the "esc" key to exit insertion mode
Typed ":wq" to save the file and exit
Rebooted the system."

aj keby som toto spravil, ale co dalej?
ako poslem magicky paket z ipadu do macbooku, aby som ho prebudil?

000001010006354000063542021096770185752107180156071801890718022707180265

pravdu mas, toto funguje len cez ethernet, nie cez wifi.
pre wifi treba zariadenie s naimplementovanym Bonjour Sleep Proxy, prip. appku, ktoru som nenasiel.
