5:00 PM

Ok, re-flashign stock -_-

Anna duh

@Bob What did you de-stock?

Bob

Because for some reason I was trying to install SuperSU 2.46 instead of SuperSU 2.79

and it spent 10 mins on the boot logo

and I got bored

soooo let's do this properly yea?

Anna duh

Also go to sleep. I don't want to feel responsible for any more poor judgement induced data losses today >_<

Bob

lol

@Annaduh well, I kinda need my phone to be usable tomorrow

and I'm pretty awake anyway

defalt

@Annaduh Lot of information is missing. So many people don't even know that PMK is sent encrypted in case of enterprise but in PSK it is never sent. It is a little different, i'm trying to find out those steps taken among YOU,AP&RADIUS.

Anna duh

5:02 PM

PMK is never sent full stop.

IEEE 802.11i-2004

IEEE 802.11i-2004, or 802.11i for short, is an amendment to the original IEEE 802.11, implemented as Wi-Fi Protected Access II (WPA2). The draft standard was ratified on 24 June 2004. This standard specifies security mechanisms for wireless networks, replacing the short Authentication and privacy clause of the original standard with a detailed Security clause. In the process, the amendment deprecated broken Wired Equivalent Privacy (WEP), while it was later incorporated into the published IEEE 802.11-2007 standard. == Replacement of WEP == 802.11i supersedes the previous security specification...

Bob

@defalt Did you end up looking at the IEEE spec I sent the other day?

Anna duh

Notice where in the diagram the PMK is being sent? It isn't

> The PMK is designed to last the entire session and should be exposed as little as possible; therefore, keys to encrypt the traffic need to be derived. A four-way handshake is used to establish another key called the Pairwise Transient Key (PTK). The PTK is generated by concatenating the following attributes: PMK, AP nonce (ANonce), STA nonce (SNonce), AP MAC address, and STA MAC address.
The product is then put through a pseudo random function. The handshake also yields the GTK (Group Temporal Key), used to decrypt multicast and broadcast traffic.

If you really want to read some detail go here: cwnp.com/uploads/802-11i_key_management.pdf

defalt

This is a handshake of PSK. Where is RADIUS server?

Anna duh

@defalt This is the handshake of 802.11i, and has nothing to do with PSK or RADIUS

Read the PDF I sent you if you insist on figuring out how RADIUS works, but bearing in mind the reason you can't find that information when looking for info on the wireless 4-way handshake is because it's not part of the 4-way handshake.

@Annaduh yup

@Annaduh also I'd actually give up with

they've been asking for what I think is a week now

and still aren't getting it.

Bob

5:13 PM

@Annaduh this pulsing boot logo is giving me anxiety issues

defalt

@Annaduh When you login with username and password in Enterprise, does the AAA key (which is created by RADIUS server and is sent to AP through wire) is that AAA key same for every client in the enterprise?

Anna duh

@djsmiley2k Oh

@defalt No

> The 802.11i amendment describes the generic process for 802.1X/EAP authentication and key management processes, which includes both generation and distribution of AAA, pairwise, and group keys. There are five specific key types that are of particular interest in the 802.11i amendment. These keys (and their 802.11i definitions) are:

Authentication, Authorization, and Accounting (AAA) Key - Key information that is jointly negotiated between the Supplicant and the Authentication Server (AS). This key information is transported via a secure channel from the AS to the Authenticator. The pa…

djsmiley2k

jointly negotiated between the Supplicant and the Authentication Server (AS)

The supplicant being the client right?

Anna duh

> The AAA Key is derived from the keying material exported by the EAP method (MSK and EMSK). This derivation occurs on the AAA server. In many existing protocols that use EAP, the AAA Key and MSK are equivalent, but more complicated mechanisms are possible

When not using a PSK, the PMK is derived from the AAA key. The PMK shall be computed as the first 256 bits (bits 0–255) of the AAA key: PMK ← L(PTK, 0, 256). When this derivation is used, the AAA key must consist of at least 256 bits.

Bob

4 mins so far...

@djsmiley2k ya

djsmiley2k

5:15 PM

Wooo I understood \o/

Anna duh

@djsmiley2k +1

djsmiley2k

Multiple Supplicants, Multiple AAA keys floating about.

Bob

5 mins...

djsmiley2k

@Bob booting again?

Anna duh

> The Supplicant and AS authenticate each other and generate a PMK. The PMK is sent from the AS to the Authenticator over the secure channel.

djsmiley2k

5:15 PM

just waiiiiiiiiiiit

breath in the blue

Bob

@djsmiley2k yea...

it took 3 mins after a stock flash

it's 6 mins and counting after a root install

which might've broken things again

went and followed these step by step this time instead of DIY droidviews.com/…

djsmiley2k

yeah this is why I stopped messing with my slowly dying phone :(

Bob

well, with newer TWRP and no-verity

Anna duh

This is obviously blatant plagiarism and unauthorised copying but the chicken farmer illustration was far too funny to pass up

djsmiley2k

tho I'm coming to you and @Annaduh next time.

Anna duh

5:17 PM

djsmiley2k

If i ever get a new phone :/

wow

Anna duh

@Bob Oh yeah, that was one I saw earlier too

djsmiley2k

that image just made sense too

because the eggs are identical

thats the key encrypting the 'golden egg'

defalt

I think now i get it..i don't know what this user was asking in the comment, i couldn't able to reply sooner see this security.stackexchange.com/questions/152999/…

djsmiley2k

\o/

then the client can decrypt it

Anna duh

5:18 PM

@Bob Bear in mind the root install should involve several restarts of its own

Bob

@Annaduh ...huh?

I restarted after first time into TWRP, after no-verity install and after root install

Anna duh

@Bob Maybe I'm thinking of CF-Auto-Root

djsmiley2k

10 minutes, til home time....

will @Bob's phone booted by then?

Anna duh

It restarts into a proprietary temporary recovery to install root, then restarts again then restores normal recover then restarts again or some shit

djsmiley2k

(Sang to 2 minutes to midnight by Iron Maiden)

Bob

5:20 PM

@Annaduh yea that's what cf does. did it work without enc?

Anna duh

@Bob Never got round to decrypting. Don't have a full backup yet.

Bob

@Annaduh ah

I'm gonna give this set a shot: forum.xda-developers.com/galaxy-s7/how-to/…

I've tied a dozen variations on that already -_-

some following instructions, some just randomly trying

djsmiley2k

eh

windows 10 warns you about syncing when it's on a meter connection... how does it know o_O

bwDraco

...okay, just got the Pro version of the network monitoring app. The customization options are remarkably extensive. Wow.

Anna duh

@djsmiley2k Either you've set it to metered or it's autodetected the IP as one of the main mobile providers?

bwDraco

5:24 PM

Thanks, @Annaduh!

defalt

@Annaduh You corrected him lol

djsmiley2k

@Annaduh if you set it to metered, does it stop it downloading huge updates? :D

Bob

@djsmiley2k it won't download updates at all on metered

AFAIK anyway

Anna duh

@djsmiley2k It stops Windows Update doing anything at all

djsmiley2k

:D

hurrar

I've solved everyones windows update issues

\o/

Anna duh

5:27 PM

@defalt I correct many people

@djsmiley2k Lol

Except you can't do it on wired connections

djsmiley2k

but wired metered is a thing

:/

hotels

people with crap ISP's

why do you haet your customers MS?

Anna duh

No, but USB and Bluetooth tethering is a thing

Metered VPNs are also a thing

Basically anything that's not 802.11 can't be set as metered

djsmiley2k

lol

microsfo y u so dumb

u cat like linux devleopner

"Coverage map won't run unless you update Google Play services"

Really now? I can't view a coverage map or do a speed test without updating google play services, but all of Google play services work fine without said update?

djsmiley2k

gps update couygh cough

defalt

5:29 PM

ok now i've got the whole story.. just a last question..how AAA key is received by the supplicant?..it has to be encrypted and decrypted somehow because supplicant is wireless..it is easy to send AAA to AP because AP and the RADIUS server are connected through wire

djsmiley2k

Right i'm off

be good kids

Anna duh

@defalt You type it in to the supplicant's username/password box

@djsmiley2k Cya

Bob

ok my eyes are getting tired now

defalt

oh yeah right..those credentials

Anna duh

I should have just said "Magic" to troll you

But alas my trolling days are over

Bob

5:34 PM

@Annaduh We're in! :D

Anna duh

@Bob Congrats!

Bob

Post-root boot worked!

Anna duh

Now I'm annoyed you've overtaken me

Bob

Also my battery charge went from 50% to 43% in the process

so yea even attached to USB you kinda need a charged battery

Anna duh

@Bob Did it take all that time? 10-15 minutes? :-o

Bob

5:34 PM

@Annaduh FYI this is what worked forum.xda-developers.com/galaxy-s7/how-to/…

@Annaduh only 5 mins on the last one

I should've just searched for XDA instructions -_-

Anna duh

My battery went from 100% to 63% when I was faffing about with it

Still never got rooted

Bob

note to self, ignore random blogs talking out their arse about android

tbh I'm not sure that I have root yet :P

gotta get through the setup screens first

Anna duh

Yeah, those blogs were the ones I was moaning about earlier

defalt

@Annaduh naa i didn't understand that point..i type my username and password and send them to authenticate..what happened next? what supplicant does after? wait for receiving AAA?

Anna duh

With shitty/incorrect/data-destroying information

Bob

5:37 PM

@Annaduh well, data-destroying was required

Anna duh

@defalt It's all in the PDF I linked

Bob

but apparently it's possible to do a backup with FlashFire before

which works fine on the encrypted => decrypted transition

Anna duh

Short story, the AAA key is generated from the shared secret information (username & password)

PMK is then generated from that via various hash functions

It's never sent or received anywhere

See farmer/chicken/egg diagram

Which I can't make any sense of yet djsmiley seemed to understand perfectly

I wonder if anyone makes a keychain SIM/microSD wallet thing

amazon.co.uk/SIM-Card-Case-including-Adapters/dp/B017C0UR1M/…

Close enough

defalt

@Annaduh but i type username and password into the browser..how they are retrieved by YOUR Operating System to generate AAA?

Anna duh

Solves sooo many of my problems

Bob

5:42 PM

O_O

Anna duh

@defalt Err... browser has nothing to do with 802.1x?

Bob

@Annaduh Battery info in settings now shows charge rate!

Anna duh

@Bob :-o

Bob

Wait no.

wtf.

> RATED DC 9 V; 1.67 A

Except I'm plugged into a computer.

IT LIES

defalt

let me check where i type username and password

Anna duh

5:43 PM

Oh that's just the phone capabilities

Bob

Well, maybe max. Bleh.

Anna duh

omgomgomgomg

Having a tech orgasm

@Bob Yeah that's the phone's max capability

Also conveniently the same as written on the stock charger

Oh fuck it's so light my body clock hasn't realised it's 7pm yet

If I had that sim case I probably wouldn't have lost my Venice photos and memory card :-(

Bob

@Annaduh ?

defalt

@Annaduh thanks for teaching

Anna duh

@Bob That SIM/memory card storage thing

So awesome

You can't imagine how good it feels to find something like that after struggling for years carrying SIM cards and memory cards around in your wallet, taped to your phone, in silly pill boxes, etc. and constantly breaking/losing them

Bob

5:48 PM

ah

@Annaduh I carry them inside an old LTE modem/hotspot with the battery removed :P

Anna duh

It's the moment of a) all my problems are solved b) this is an amazing innovation and c) Someone else has the same issues as me, I feel so understood!

@Bob Lol, would that fit 2-3 SIMs and 2-3 memory cards and still fit in my pocket? :-P

Bob

@Annaduh ...yes?

it'd fit 20 microSDs easy

Anna duh

The S4 LTE-A is 50% faster than the LTE, and the box is also 50% wider...

@Bob Oh you mean in the battery compartment

Bob

lol yea

Anna duh

I thought you meant the actual SIM slot :-P

Most hotspots around here are quite thick, usuallly 1cm+

Anyway should be off to pub

But so many things to do and so much stuff on my mind my brain is a bit overloaded

Also want to root my phone but it seems Bob's beat me to it

That said, should be able to easily backup and root and reflash my phone at the pub, cept I'd have to take my laptop for just one of the flashing parts :-(

Unless I downgrade then use flashfire but meh.

128GB memory card ftw...

Bob

5:52 PM

@Annaduh yea about 1cm

ugh

TiB really needs a way to select multiple to restore

Anna duh

@Bob it has?

Hasn't*?

Bob

huh. whoops.

I backed up the wrong camera folder

there goes my photos

Anna duh

._.

Ouch

Bob

turns out "Camera" was teh folder I originally copied from my G4

DCIM was the S7 one

whoooooooooooooooooooops

and here I thought "oh I don't need to copy every dir, that'd take too long... it's mostly music anyway!"

oh well, i'm not recoering that data... encrypted and all

Anna duh

Urgh some drunk twat spewed on my motorbike and used my glove box as an ashtray

The text in this chat is mostly fine but the text in the typing box at the bottom is pretty bad

@Bob there's a second page?

Ooh heh didn't notice there was a second page

@Bob did you give up on sleeping?

Oh yeah there's a second page. Fuck that's confusing.

You can't scroll left and right while the thing is collapsed and there's no indication at all on the expanded screen or on the edit/customise page that you can swipe left or right at all

@Bob have you found any way to get rid of the search phone box?

@Annaduh slept for like half an hour

I think I'll go through my last teabags today :P

@Annaduh tbh I actually found that on my Xperia first!

@Annaduh nope, it doesn't bother me much

oh so that's where quick connect went

Anna duh

@Bob oh

There's definitely no left or right scroll on my xperia notification toggles

(just checked for missing icons on my xperia... :-P)

Bob

@Annaduh what do you think about the new font?

Anna duh

I could just Encrypt my SD card and move all the stuff to there

@Bob there's a new font? Didn't notice

Bob

@Annaduh is yours on nougat?

Anna duh

@Bob yes

I do have a theme from the Samsung theme store applied though, so it might be different?

Bob

10:20 PM

phew, just made it on the train

@Annaduh small zoom?

DavidPostill

@MichaelFrank They could be if they give you RSI. I can't use a normal mouse for exactly that reason (I use a trackerball to avoid RSI in my arm/wrist from moving a mouse about).

Anna duh

@Bob shrug, forgot why I did that. Probably when I was messing with 720p

Michael Frank

@DavidPostill Yes, but you can get ergonomic wired devices. I'm talking about the wires themselves. :P

Anna duh

@Bob looks like the same font as mine.. Can't really tell the difference

The aspect ratio of the notification bar icons look slightly different but that might also be something to do with my resolution settings

DavidPostill

@MichaelFrank I suppose you could trip over the wires when you dance on your desk :)

Bob
