Root Access

> Once it has finished it will boot into a screen saying "Erasing" this is fine, it will shutdown and reboot and linger on a pulsing samsung logo, this is fine.

defalt

@Annaduh It is similar but not alike

Bob

> this is fine

f. m. l.

@Annaduh I suppose this is your revenge :P

Anna duh

4:26 PM

@Bob FML too

bwDraco

Just an FYI to the community: My availability is going to be very limited over the next ten days as I have lots of sports photography to do. The weather has not been kind lately so a whole bunch of games got rescheduled for the coming weeks.

Anna duh

I told you to go to sleep

This is insomnia's revenge!

Bob

lol

@Annaduh did yours do the same?

Anna duh

@Bob FML? or This is fine?

bwDraco

My schedule is going to be jam-packed next week.

Bob

4:27 PM

@Annaduh pulsing logo

Anna duh

Oh the breathing Samsung logo? I don't get that cause mine's encrypted, I just get the unlocking logo

defalt

@Annaduh Do you have any link where I can read about it?

Bob

@Annaduh oh.

Involvement of RADIUS server makes its handshake process different

Anna duh

4:28 PM

> The handshake is the same if its a PSK or 802.1X.However the orignal keying material used to start the authentication process is derived differently. The PSK uses the actual phase phrase for seeding material in the 4 way key handshake.While the radius server uses a random AAA key generated during the EAP process. This keying material is used for the seeding martial in the 4 way handshake.

Bob

defalt

That doesn't explain what happens in the handshake process of enterprise

djsmiley2k

@Bob git gud.

Anna duh

@Bob: Nope, still no fast change with screen on

@defalt That just describes exactly what happens

> However the orignal keying material used to start the authentication process is derived differently. The PSK uses the actual phase phrase for seeding material in the 4 way key handshake. While the radius server uses a random AAA key generated during the EAP process.

Bob

fack. I just needed to wait 3 mins the first time, probably

Anna duh

4:32 PM

> 5 Things are needed for the handshake -

PSK or Master Key

Snonce

S mac address

Anonce

A mac address

The Ap sends the first handshake. Inside this frame is its Anonce and mac address both derived from the PSK or Master Key. The client at this point has the UNICAST keying material, because it knows its own Snonce and S mac address. The client then sends its Snonce and S mac address derived from the PSK / Master key to the AP. The Ap now has enough to derive the key for UNICAST.

Bob

sigh. time to restore apps one at a time -_-

Anna duh

@Bob Err...

Just 3 minutes? :-o

Well yeah, that happens after every major update, basically the "Android is upgrading" or "Optimizing apps" bit is hidden now I suspect

Bob

@Annaduh well, that's the time the logo spent pulsing before it got to a progressbar. on a fully flashed (no data) phone

omg

Anna duh

I took so long reading how to root while it was rebooting I didn't even notice the 3 minutes, but yeah, it does say allow 5 minutes for first reboot -_-

Bob

there's an auto-reconnect option for wifi networks

:D :D :D

ffs, this shouldn't be new

bwDraco

4:33 PM

@Annaduh androidpolice.com/2016/10/21/…

Bob

T&Cs...

*taps agree to all*

bwDraco

It's also a lot faster than it used to be.

Bob

waiiiiiiiiiiiiiiit a minute

defalt

In enterprise PMK is sent encrypted while In PSK PMK is never sent..That's why I'm trying to find the exact steps of its handshake

Bob

marketing information?!

*unticks*

Anna duh

4:34 PM

@Bob :-o

@Bob Oh yeah, that

My Sony had that since Android 4.4

:-O did not notice it there on my Samsung

Bob

@Annaduh I'm pretty sure my S4 had it

Anna duh

ffs this is amazing, this shouldn't be new

@Bob Mine didn't :-(

Friggin awesome it's finally turned up though

Bob

o.O

@Annaduh yea I kept having to delete my work network

cause I only wanted to be on it sometimes

and digging up the password every time was a pain

windows has had it since Vista FFS

(Vista also being the first time Windows had wifi support at all)

wait, no, xp did have wifi autoconfig

it was just half broken

Anna duh

Both transactions are encrypted with a KCK,KEK, TL, keys. Going off memory here…

The 3rd and 4th handshakes are for the broadcast key.

Do I really have to copy and paste every line from the link?

@Bob Ergh. I just turned off wifi as my workaround

Bob

@Annaduh I tended to keep wifi on :\

shit, I knew I forgot something

Anna duh

4:37 PM

But yeah, one of those things I've been feeling should have been there for years since I got the whole "Sony seems to put so much more effort into the little things" when I got my Z3C

Bob

should've enabled google backups before updating

Anna duh

@Bob Well if I didn't want it to connect to my work network while at work I'd just turn off wifi

defalt

@Annaduh let me read first and then i'll ask what is missing in it.

Anna duh

Same for most other networks tbh.

djsmiley2k

I have wifi on all the time

screw the idea that I need to micromanage my phone

if this is what it takes to have a longer battery life, I don't want the flippin phone

Anna duh

4:38 PM

It's unusual for me to want it to autoconnect to anything which isn't the main network I'd connect to in a certain place

Bob

@Annaduh I had that hotspot :P

Anna duh

@djsmiley2k Eh, I use mine often enough simply walking out of the house that it's trivial and normal for me to keep toggling it

Too lazy to wait for the 15-30 seconds or so it takes to time out and disconnect from my "home" wifi as I walked out of the building, was quicker just to swipe down and turn it off.

Otherwise data would be basically non working during the most important part of my walk from home to the bus stop, right when I needed it to find out when the bus would be coming

Oh and also having my wifi reach the bus stop (very weakly) wasn't too helpful either, cause sometimes it'd sporadically connect and time out while sitting at the bus stop

djsmiley2k

@Annaduh yeah but I've got a life.

i've got 2 kids, a house, a wife.

No time

Anna duh

@djsmiley2k So you never leave the house?

djsmiley2k

No, I'm constantly in and out of places

Anna duh

4:41 PM

Or just never use the phone while leaving the house?

djsmiley2k

it's petty much like that now yes, because the phone dies

Anna duh

Also we have public wifi in a lot of places which keeps coming on and off but being too weak to use as I walk around the building or the high street

djsmiley2k

I don't connect to the public wifi at places unless i'm sticking around

Anna duh

So really I just keep wifi off unless I specifically want to connect to it somewhere

djsmiley2k

see if I do that, my battery dies from trying to get data

can't win :(

Anna duh

4:42 PM

@djsmiley2k Me neither, but our public wifi is often a lot faster than the wifi supplied by my hostel/accomodation...

@djsmiley2k lol you need a better phone

My Z3C survives 6+ days with 4G data on 24/7

djsmiley2k

yes, yes I do

but no money, mo problem

Nick Alexeev

Would this be on-topic for SuperUser? I'm inclined to migrate it, because SuperUser folks would be more knowledgeable about the practical side of this.

Q: does heat kill hard drives? hhd lifespan due to heat

These days it's hard to buy an external 3.5" hard drive with a fan inside or well heat dissipation design. I have 4 of such hard drives, and two have already failed in first few months. Here is the deal; They all run very hot in few minutes of copying some files. Some show 50 max and some 70 max...

bwDraco

It seems to be okay, but would need some editing to remove some opinion-based content from the question.

djsmiley2k

Well it's hdd...

bwDraco

> Why all manufacturers suddenly choose to not include a fan?

That's opinion-based and should be removed.

djsmiley2k

4:49 PM

To me it reads 'I'm buying cheap drives and they die, what gives?'

Anna duh

@NickAlexeev Yeah based on the title

No based on djsmiley's description

bwDraco

It's an otherwise meritorious question, but it needs to be edited.

As it stands, no.

djsmiley2k

So ontopic? Yes, suitable? No.

but we're not mods! :)

People ask far worse questions every day.

defalt

You know that person managed to write each numbered steps to explain WPA2 PSK but when it's come to explain about WPA2 Enterprise they just tell you that radius server uses AAA. That link was not helpful. Handshake is combination of steps with the participation of RADIUS server and steps of who sends what

Bob

@NickAlexeev I swear we have a duplicate

Anna duh

4:55 PM

facepalm

@defalt Because as stated before, it's identical except for the actual PMK derivation

This should be simple enough to sort out
