12:25 AM rue_mohr: polprog,
12:30 AM rue_mohr: you want an isa graphics card eh?
12:30 AM polprog: good morning rue
12:30 AM rue_mohr: I got spares
12:30 AM rue_mohr: its still tonight
12:30 AM polprog: oh, nice
12:30 AM rue_mohr: whats the project, shall I 'sponsor' it?
12:30 AM polprog: its 0720 in the polprog land
12:30 AM rue_mohr: 22: here
12:30 AM polprog: Ive got some 486 builds that lack PCI that i want to boot up
12:30 AM rue_mohr: ah
12:30 AM rue_mohr: whats special about them? how far are you otherwise?
12:30 AM rue_mohr: ugh, a simple video of my cat is going viral
12:30 AM polprog: your cat?
12:32 AM rue_mohr: ah
12:32 AM rue_mohr: what you gonna do with them then?
12:32 AM polprog: probably run bsd/dos
12:33 AM rue_mohr: mmmhmm
12:33 AM rue_mohr: is that a graphics lcd?
12:33 AM polprog: No, its a hd44780
12:33 AM rue_mohr: huh. large print?
12:34 AM polprog: yeah. two lines
12:34 AM rue_mohr: two!!
12:34 AM rue_mohr: hahah
12:34 AM polprog: what? not enough? :p
12:34 AM rue_mohr: if I could do FPGA I'd make a driver for my graphics screens
12:34 AM polprog: apropos graphics LCDs ive got 3 from a xerox machine
12:35 AM polprog: big monochrome graphic, you know
12:35 AM rue_mohr: I'm just posting a video...
12:35 AM polprog: havent got them running yet
12:35 AM rue_mohr: I have a bunch of graphics ones
12:35 AM polprog: they have a cool EL backlight panel
12:35 AM rue_mohr: they dont have memory/drivers tho
12:35 AM rue_mohr: yes
12:36 AM polprog: did you read my latest post? on dumping flash?
12:37 AM rue_mohr: ? did twitter swallow it??...
12:38 AM polprog: maybe
12:38 AM polprog: https://polprog.net/blog/wag54g/
12:39 AM rue_mohr: wag is the newer one, yes?
12:40 AM rue_mohr: does it still have the top secret serial port?
12:40 AM rue_mohr: (that 2x5 header I think, two serial ports)
12:40 AM rue_mohr: one has the system console on it
12:41 AM polprog: no, its an old adsl gw
12:41 AM polprog: i bet my wrt54gl is 'younger'
12:42 AM polprog: 2x5 header? can you see it on the pic?
12:42 AM polprog: ive found one uart
12:42 AM polprog: and one jtag
12:43 AM polprog: do you like the ascii art :v
12:44 AM rue_mohr: :)
12:45 AM rue_mohr: interesting what software they incorperate into them eh?
12:45 AM polprog: Ive got the hex dump, its bare metal arm assembly
12:46 AM polprog: binwalk only found a copuright string
12:46 AM rue_mohr: oh
12:46 AM polprog: and bits of HTML scattered around, the web interfave
12:46 AM polprog: face*
12:46 AM rue_mohr: I thought they used someones OS
12:46 AM polprog: its a simple cpu, no mmu even
12:46 AM polprog: only uClinux could run
12:46 AM polprog: i can give you the dump if you want, 2MB
12:47 AM rue_mohr: cut down quite a bit from the wrtg54g
12:47 AM rue_mohr: no, hell I got enough distractions
12:48 AM orlock: polprog: Eurgh
12:48 AM orlock: polprog: https://openwrt.org/toh/linksys/wag54g - seen that?
12:49 AM polprog: yep
12:49 AM polprog: ive seen it all
12:49 AM orlock: Unless you are broke and curious with lots of free time, bin it...
12:49 AM polprog: it still works as a switch
12:49 AM polprog: i just wanted to play with jtag as i havent before
12:49 AM orlock: ahh, k
12:50 AM polprog: now im trying to hack into something i *know* runs linux
12:50 AM orlock: .. barely...
12:50 AM polprog: (cause it has a root shell on the serial port huehue)
12:50 AM polprog: what barely?
12:50 AM rue_mohr: heh, I wonder how long it would take ya to get into one of the arm based HP multifunction printer controlles I have
12:50 AM orlock: barely runs linux
12:50 AM polprog: nah, its a ppc based DBR
12:50 AM polprog: DVR*
12:51 AM orlock: damn half of the IoT seems to be DVR's now
12:51 AM polprog: bbl, breakfast and then monday boredom tortures
12:51 AM orlock: i got a shell on one last week
12:51 AM orlock: nc straight to an open socket
12:51 AM orlock: it was popped, and somebody left a shell just running
12:52 AM orlock: like leaving the keys in the ignition of a stolen car
12:52 AM orlock: polprog: seen the gl.inet devices?
12:53 AM polprog: nope
12:54 AM polprog: lol open telnet
12:54 AM polprog: well
12:54 AM polprog: a device in my jurisdiction is root:1234
12:54 AM polprog: on ssh
12:54 AM polprog: so yeah
12:54 AM polprog: IoT lolz
12:54 AM orlock: Internet of Shit
12:56 AM orlock: and i dont even mean just telnet
12:56 AM orlock: they literally had the shell running right on the socket
12:56 AM orlock: no l/p
12:56 AM orlock: nc
12:56 AM orlock: bam
12:56 AM orlock: shell
12:56 AM polprog: lol
12:56 AM polprog: well
12:56 AM polprog: we will have a lot of work in the future
12:57 AM orlock: and then, on the other hand, there's the ones that spit linux malware back at you\
12:57 AM polprog: "hello? polprog inc.? My coffee maker is monkng shitcoin!"
12:57 AM polprog: lol what
12:57 AM orlock: not ftp or http or anything
12:57 AM orlock: tcp connection to the socket
12:57 AM orlock: immediate binary stream
12:58 AM polprog: hmm
12:58 AM polprog: bbl
12:59 AM orlock: 5377e8f2ebdb280216c37a6195da9d6c
12:59 AM rue_mohr: error: bad checksum
01:03 AM mrdata: c0re dumpt
01:08 AM rue_mohr: uuuuh
01:09 AM rue_mohr: unless I'm wrong, it takes 3 io commands to init a vga card
01:13 AM rue_mohr: er no
01:14 AM mrdata: wouldnt that depend on the card?
01:17 AM rue_mohr: er nostrictly dealing with T8900
01:17 AM rue_mohr: god man, its for a z80 I'm not trying to kill myself
01:17 AM rue_mohr: I think its thin enough I could port it
01:18 AM rue_mohr: http://tinyvga.com/avr-isa-vga
01:19 AM rue_mohr: I might be wire to do a 16650 first tho
01:19 AM rue_mohr: wise
01:26 AM * orlock has done nothing interesting recently
01:26 AM orlock: i think i want ti MitM the vac though
01:27 AM zhanx: i am on higher ground so ok if it does change course
01:28 AM rue_mohr: :/
01:28 AM zhanx: got some rain from it today but it, if goes into the gulf it will hit me
01:29 AM orlock: zhanx: it's a cyclone, not a sith lord!
01:29 AM orlock: Hold on... Nevermind.
01:52 AM polprog: Need to make space on the windowsill for a parport enabled computer
02:06 AM mrdata: MitM the vac??!?
02:07 AM orlock: mrdata: IoT robovac
02:07 AM mrdata: wonderful
02:07 AM mrdata: do it
02:08 AM mrdata: i want to see the video of it going on a rampage
02:08 AM mrdata: people screaming and fleeing
02:08 AM mrdata: etc
02:23 AM polprog: 0xF0- enable the body chipper
02:23 AM polprog: 0xF1- full steam ahead
03:52 AM polprog: motherfuckers spoilt ALL THE FUN!!!
03:52 AM polprog: https://i.ibb.co/rHkHv9n/IMG-20190902-104253.jpg
03:58 AM rue_bed: hahaha
03:59 AM rue_bed: whats that on?
04:05 AM mrdata: is that 'label' for a microcontroller chip?
04:09 AM mrdata: at least you know where to connect the linux console connector
04:11 AM polprog: thats where some label was
04:11 AM polprog: rue_bed: a DSL router
04:11 AM polprog: ive got a couple of units pulled from the trash
04:12 AM polprog: colelcted over time
04:12 AM polprog: bought on flea markets
04:47 AM logb0t_ is now known as logb0t
08:57 AM gartt: I never understood IoT. Never made sense. Yes, some things can be automated, but the perceived convenience vs security trade-off doesn't seem worth it
09:05 AM deshipu: generally automation rarely makes sense outside of industrial settings
09:05 AM deshipu: more work setting it up and maintaining it than what you save
09:09 AM gartt: And anyway, if I'm going to automate some devices, I want to do a poor man's IoT anyway, with devices connecting to my home server, and then me getting to my home server via SSH or a web app to view/manage/control them for much more flexibility and security
09:10 AM gartt: The whole new "have your fridge alert you when you're out of milk" refrigerators seem absurdly stupid to me
10:19 AM Tom_L: gartt, it's for the humans than can't think for themselves
11:05 AM gartt: In that case, I'm due for 3 of them
12:37 PM mrdata: so long as that fridge doesnt climb into my bed because it's moody, i'll be fine
01:49 PM veverak: deshipu: https://youtu.be/0fqngunWmeU
01:49 PM veverak: got it more stable now
03:14 PM gartt: NASA was originally working on a standard walking robot for use delivering coffee and snacks to NASA employees. However, when it took a bad spill down five flights of stairs and was discovered to be still largely operational it was re-purposed as a 'mountain climbing robot'. -Slashdot poster
03:14 PM gartt: Heh, had to share
03:15 PM veverak: lol
06:19 PM logb0t_ is now known as logb0t
10:10 PM rue_mohr: hi
10:10 PM zhanx: <Casper> does anyone have an idea why I get "avrdude: stk500v2_command(): warning: Sampling of the RDY/nBSY pin timed out" after I write the boo
10:11 PM zhanx: casper is worried you will answer with weirdness
10:11 PM zhanx: otloader? (as in right after it actually write the bootloader code)
10:11 PM zhanx: <Casper> https://paste.debian.net/hidden/8356b327/ <=== like that
10:11 PM zhanx: might help if i pasted it all
10:11 PM rue_mohr: ready busy!?
10:11 PM rue_mohr: I'v never even heard of that
10:12 PM Tom_L: is it a stk500 programmer?
10:12 PM Tom_L: or something else
10:13 PM Tom_L: that isn't a pin that will 'get you in trouble' is it?
10:13 PM rue_mohr: oh I'm thinking 200
10:13 PM Tom_L: like the reset pin on some of them
10:13 PM rue_mohr: he just be using jtag?
10:13 PM Tom_L: i don't know what he's doing
10:14 PM Tom_L: zhanx is he in #avr?
10:14 PM rue_mohr: says isp
10:14 PM zhanx: no #arduino
10:14 PM Tom_L: i haven't been there in a very long time
10:14 PM zhanx: i stopped going to #avr due to the people there
10:14 PM Tom_L: it got split
10:14 PM rue_mohr: yo9u should jsut tell me which people to kick out
10:15 PM zhanx: after the mass kick? yea no
10:15 PM rue_mohr: it was only a kick
10:15 PM zhanx: i know it was mainly bots etc
10:15 PM rue_mohr: I shouldn't have done it after that damn movie
10:15 PM rue_mohr: I thought people were more mature
10:16 PM Tom_L: damn i didn't realize the bot was still there
10:16 PM rue_mohr: Tom_L, do you think its a pin or a flag its looking at
10:16 PM chisight: will give it a try.
10:17 PM zhanx: rue, tom, chisight
10:17 PM zhanx: hacker also
10:17 PM chisight: hi folks. o/
10:17 PM zhanx: likes to make fun stuff
10:18 PM rue_mohr: #!$%@$%^!# almost 3200 views on that instructables!
10:18 PM rue_mohr: damn!
10:19 PM chisight: been hacking on https://github.com/noproto/WhiteBeam recently. got the first bug bounty, hope to get the next one. cheated on round two (but owned it long before accepting a bounty)
10:21 PM zhanx: nice
10:22 PM zhanx: making my cider for xmas right now so in and out
10:22 PM Tom_L: can't say i've seen that error
10:22 PM chisight: they took away LD_PRELOAD=
10:23 PM Tom_L: what avr is it?
10:23 PM chisight: hey rue_mohr and Tom_L
10:23 PM Tom_L: and what is 'boo'
10:23 PM Tom_L: a bootloader?
10:23 PM * chisight listens to hear what the conversation is about.
10:24 PM Tom_L: iirc the thing about bootloaders is you need to have the fuses in place too or it won't jump to the right place
10:24 PM Tom_L: this may not have anything to do with your error...
10:24 PM Tom_L: i haven't touched an avr in a long time either
10:25 PM mrdata: fuses?
10:26 PM Tom_L: you don't know what a fuse is?
10:33 PM chisight: mrdata: fuses are cpu settings controlled by a special block of flash that do low level things like controlling which pins are active or how programming/reading can be done.
10:33 PM Tom_L: what avr is this?
10:34 PM Tom_L: 328?
10:34 PM mrdata: chisight, back in my day, once you blow a fuse you cannot unblow it
10:34 PM Tom_L: 2560?
10:34 PM Tom_L: you can rewrite them
10:34 PM mrdata: but is this different?
10:34 PM mrdata: ok
10:34 PM Tom_L: more like a breaker?
10:34 PM chisight: mrdata: yeah, it's a misnomer. oh well.
10:36 PM danst: noodle: hey
10:39 PM zhanx: ok done
10:50 PM mrdata: chisight, kind of serious one imo
10:50 PM mrdata: it might cause... confusion
10:51 PM mrdata: so to speak
10:51 PM chisight: mrdata: eh, i don't set the terms. the industry seems to have accepted it.
10:51 PM chisight: fuses are now resetable. oops.
10:52 PM mrdata: latch would be the more correct term
10:52 PM mrdata: oh well
10:53 PM chisight: agreed. but it is what it is. :-/
11:53 PM fling_ is now known as fling
