foobarryanyone know a good source of 8 bit arcade/geek style gifs and pngs?11:39
foobarryrather than HD stylised versions which google seems full of11:40
foobarryjust doing google image search for 16x16 pics atm11:42
ali1234there's a website dedicated to ripping graphics from old 8 and 16 bit games, and then making gifs out of them11:51
ifm@search feynman11:51
ali1234i can't remember what it is called but let me see if i can find it11:51
ali1234foobarry: http://spritedatabase.net/11:55
foobarrycool thanks ali123412:42
foobarrytrying out the new solus release13:00
foobarrythe max brightness doesn't seem as bright as other OS :|13:03
ali1234that ubuntu gnome shell stuff is looking really really good15:32
klystronhi is there anyone who can help on log files17:09
klystron18:03 <klystron> 18:01 <klystron> my question is this if I have a webcam or imaging device connected to a computer which can control the device can I see all log information that takes place in relation to time stamped/communications and access and storing images using a log file?17:09
klystron18:03 <klystron> 18:02 <klystron> i.e. all process and transactions that take place between the computer and the device?17:09

daftykinstime to reg and ask in #ubuntu which is the main support channel17:14
daftykinsyour request doesn't sound particularly kosher...17:14
ali1234klystron: you want an audit log for webcam usage?17:18
diddledanmust.. resist.. suggesting.. concerns.. over.. sexting17:19
ali1234or do you want to sniff the raw protocol information?17:19
ali1234the latter can be done with https://www.kernel.org/doc/Documentation/usb/usbmon.txt17:20
brian_hi is there anyone who can help on log files17:20
brian_18:03 <klystron> 18:01 <klystron> my question is this if I have a webcam or imaging device connected to a computer which can control the device can I see all log information that takes place in relation to time stamped/communications and access and storing images using a log file?17:20
brian_18:03 <klystron> 18:02 <klystron> i.e. all process and transactions that take place between the computer and the device17:20
ali1234if you need stuff like audit logs then ubuntu might not be for you. maybe RHEL can do that17:20
brian_this is a general question about logs17:21
ali1234(18:18:49) ali1234: klystron: you want an audit log for webcam usage?17:21
ali1234(18:19:28) ali1234: or do you want to sniff the raw protocol information?17:21
brian_yes or any imaging device that is connect17:22
ali1234which?17:22
brian_what i am trying to establish if you connect and control a device to any linux or window based system there will be a log file time stamped and audit showning all that takes place between the device and computer - yes or no?17:23
ali1234not by default no17:24
brian_why17:24
ali1234because it would fill up your hard drive quite quickly17:24
ali1234in the case of a webcam at least17:24
ali1234some things are logged, such as connecting devices17:24
brian_i was not awar i was in here three times17:24
daftykinsyes, you seem to be new to IRC?17:27
brian_if we are talking about a CT image scanner surely there would be an audit trail as to who logged on when the system was idle and in use17:27
ali1234yes, almost certainly17:27
ali1234but you specified "any" system17:27
ali1234most are not connected to CT scanners17:27
brian_a toshiba17:27
daftykinsphew i thought i was in a hospital then, thank Tux for that17:27
ali1234as i said, if you need that kind security and auditability, then RHEL is your best bet17:28
diddledanreally? mine is connected to one...17:28
daftykinsdiddledan: clearly it's all about ATMs for home connection right now17:28
brian_possibley connected to a mac17:28
ali1234not all operating system work the same. not even all version of linux17:28
daftykinsbrian_: you're not making a lot of sense.17:28
ali1234it makes sense to me17:29
diddledandaftykins: you mean an asymmetric teletype modem?17:29
diddledan:-p17:29
brian_i dont think you understand what i am talking about17:29
daftykinsdiddledan: nah not today17:29
daftykinsi'm on about being on IRC multiple times, hah17:29
brian_if you went into hospital and had a xray or ct scan the scanners would have an audit trial as to its use and by whom17:30
ali1234yes17:30
ali1234that is correct, at least one would hope17:30
brian_that audit trail would be the log files17:31
ali1234the audit trail would be in the CT scanner software17:31
brian_on the controlling computer system or O/S17:31
ali1234the operating system itself does not provide it, unless you program it to do so17:31
diddledanhint, not many people in here are likely familiar with CT scanners17:31
ali1234you odn't need to be familiar with CT scanners to answer this question17:31
diddledanif you're not familiar with CT scanners then you can only answer hypotheticals was what I was suggesting17:32
daftykinsyeah, leaves a bit of room for accuracy17:33
daftykinsor inaccuracy, rather17:33
brian_so that log file be it OEM of the CT scanner computer system or any computer controlling the scanner would have log files as a means of an audit trail17:33
diddledanNYANDOWS! https://twitter.com/ctrl_alt_steph/status/90113524440057446417:33
diddledanI still love the orange version: https://www.youtube.com/watch?v=0XrRwruU8DE17:34
ali1234brian_: maybe, but who knows?17:35
brian_i would think so for as the files are medical records and a audit trail to se who loged on and when the machine was in use17:36
ali1234yes, regulations probably require it17:36
brian_in case there was any dispute17:36
brian_ok assuming that was the case of the log files providing an audit trail - then next question is can any log files be manually edited?17:38
ali1234depends on your definition of "any"17:38
ali1234it is possible to design a logging system which cannot be edited without leaving evidence that it has been edited17:38
diddledan^ that17:38
ali1234but that does not mean that no log file can be edited17:38
brian_so if we take the case of a network and the logs would someone be able to change or edit log files17:39
diddledanis this homework we're doing for you perchance?17:39
brian_just a network17:39
diddledan-_-17:40
ali1234no, merely using network logging is not enough to prevent logs from being modified17:40
daftykinshonestly just get to the point17:40
brian_so if a logging system was designed so as not be edited what evidence would it leave if it had been edited?17:41
brian_or hacked?17:42
brian_would it use a blockchain?17:43
ali1234that is one possibility17:43
brian_what are the other possibilities?17:44
ali1234it depends what type of attacker you want to defend against17:44
diddledanALL the attackers17:45
ali1234that is impossible17:45
diddledan:-p17:45
brian_are they any PEN test that can determine if a lof file has been edited?17:45
brian_log...17:45
ali1234it depends on the log file17:45
brian_name some?17:46
ali1234no17:46
diddledanthis really sounds more and more like homework17:46
ali1234also, that's not what a pen test is17:46
ali1234if you have a secure logging system then it will have the capability to detect changes right in the software17:46
brian_frensic software tools17:47
brian_how would or could you determine if a file has been edited which is part of an audit trail?17:47
diddledanhttps://twitter.com/GeekandSundry/status/90113901979433369617:48
diddledanRUUUUNNNN17:48
ali1234you store a hash of the file somewhere immutable like in a public blockchain, or just on write-only media17:49
ali1234then you compare the document to the hash later17:49
ali1234if the hash does not match, it has been modified17:49
brian_yeah but that requires you to have both #17:49
ali1234yes17:49
ali1234cryptography isnt magic17:50
brian_but a blockchain will show if its been  edited further up the transaction - like bitcoins17:50
ali1234that statement does not make any sense17:51
diddledana blockchain can only be validated from end-to-end - you can't take a single transaction and say "that's modified" without checking the rest of the chain17:51
diddledanblockchain modifications just cause a fork17:52
brian_ok blockchains transaction have # from a previous transaction if a transcation is edited or changed the # will be different and will ripple up to all other transaction17:52
ali1234you mean blocks17:53
ali1234and yes, that is special form of a merkle tree17:53
* diddledan swoons at the mention of her almighty17:53
brian_# from one file or transaction will be combine with another #17:53
ali1234yes17:53
ali1234the way you implement that in a log file is you put the hash of the previous line into the current line, and then hash the current line17:54
brian_so if a file transcation is edited that will generate another different #17:54
ali1234this is not a new idea by any means. it pre-dates blockchains by a very long time17:55
ali1234git also does this17:55
ali1234every commit contains the hash of the parent17:55
ali1234so you can't modify a commit deep in the history without modifying every following commit17:55
brian_so the blockchain further up would show where a transaction or file was edited17:56
ali1234something like that17:56
brian_ok so in answer to the log file if a blockchain system was employed then any editing of a file would be shown on other such log files yes/no?17:58
ali1234a hash chain17:58
brian_is that a yes or no?17:58
ali1234the hash of all log entries after the edited one would change17:58
brian_ok17:59
ali1234but you have to be able to tell that they changed17:59
ali1234otherwise it is useless17:59
brian_and could not be changed back unless the origional transcation or file was replaced by the edited one18:00
ali1234the only way to change it back is to put the log back to how it was before you edited it18:00
ali1234OR find a hash collision, which is very difficult18:00
brian_i.e the edited file was replaced with the origional unedted file18:00
ali1234yes18:00
brian_ok18:01
ali1234the key to making it work in practice is with commitments18:01
ali1234ie you release only the hashes, not the log18:01
ali1234the hashes alone do not give any information but can be used to prove the log is unmodified later18:01
ali1234eg this is used in provably fair gambling18:02
brian_so you would have to compaire #then18:02
ali1234yes18:02
diddledanis there a point coming soon?18:03
ali1234what do you mean point?18:03
ali1234hey does anyone remember ages ago when i asked:18:04
ali1234if two people have secret numbers, can they compute the bitwise AND of their numbers, without revealing the numbers to each other?18:04
ali1234well it turns out the answer is yes18:04
daftykinso018:04
diddledanis that not the basis of RSA?18:04
ali1234no, not at all18:04
brian_so if a logging system that had to be secure against any editing of personal data i.e. CT scanning would have to have the basis of the provably faim gamming # system18:05
ali1234RSA is encryption18:05
ali1234it isnt the basis of DH key exchange either, which is what this channel said last time :)18:05
ali1234brian_: no, that is an over-simplification18:06
ali1234anyway it turns out the problem i stated can actually be solved for any boolean logic circuit built from AND and OR gates18:06
ali1234but what i found interesting about this is AND/OR gates are not universal18:07
brian_what would be a system that could protect the audit trail18:07
diddledanbig dude with a gun18:08
daftykinsyep definitely sounds like homework18:08
ali1234yes i agree18:08
diddledanI called that ages ago18:08
daftykinsbrian_: you're an idiot18:08
brian_really18:08
daftykinsyep18:08
brian_speak for yourself18:08
ali1234nah it's fine. i'm not going to just give you things you can copy paste into your paper18:09
ali1234you'll have to rewrite it in your own words18:09
daftykinsi think i do speak for myself :>18:09
diddledanthis channel is logged anyway, so we can always prove that it happened18:09
ali1234but the logs are not hashed18:09
brian_maybe its in your first nick name daft18:09
diddledanof course we'd need to ensure it ^ that18:09
diddledandafty*18:10
ali1234anyway you should go and look up "non-repudiation" on google. and "hash chains".18:10
brian_this is no homework or paper excerise18:10
daftykinsand maybe how to study18:10
brian_well you did not even undestand my origional question only one person did18:11
daftykinsyou assumed a bit there, i mostly had issue with the multiple clients and crossposting18:12
brian_and im no idiot!18:13
diddledanspeak for yourself. I'm definitely an idiot18:13
daftykins:D18:14
brian_and have not come into chat for a slanging match either or name calling which must be against the rules of freeserve and IRC18:14
diddledanI take umbridge over the suggestion that I'm "normal"18:14
ali1234we have this same argument like one a week18:14
diddledanali1234: is that because people insist on thinking I'm sensible?18:15
brian_i think freeserve sould have a button to report abuse and ban those people18:15
daftykinsi don't think anyones used freeserve in years18:16
diddledanI used to be on freeserve18:16
ali1234me too18:16
ali1234it was free18:16
diddledanthen orange18:16
daftykinsi remember magazine discs18:16
ali1234so why not?18:16
ali1234i had an autodialer to reconnect after the 59 minutes or whatever it was18:16
diddledanI've probably still got a freeserve disk somewhere18:16
diddledanI believe it was 1hour 59 minutes for the cutoff18:17
brian_well the ubuntu-uk should have a abuse button then18:17
daftykinsyep abuse from homework requesters :)18:17
ali1234it does, but if you press it, a human comes and looks at the channel and decides what to do18:17
* diddledan prods the button18:17
brian_its not omework what makes you that?18:17
ali1234kind of like the emergency brake on a train18:17
ali1234if you pull it when you shouldn't have, people get annoyed18:17
diddledanI need to watch guardians of the galaxy 218:18
daftykinsah that's still on my to-do list18:18
diddledanI also need to eat dinner18:18
ali1234brian_: prime reason we think it is homework is because you are asking questions but you don't seem to understand the terms in the questions, like you didn't come up with those questions yourself18:18
brian_so any technical question then according to you is homework then18:19
daftykinsplus irrelevant channel for it18:19
ali1234that's not even close to what i said18:19
diddledanno. long question chains which have no discernable destination are indicative of homework18:19
brian_well then it cant be homework then if its an irrelevant channel18:20
ali1234why did you pick this channel to ask, btw?18:20
ali1234just wondering18:20
ali1234there are plenty of channels on freenode devoted to crypto and security18:21
brian_i just wanted someone who as knowled of log files and whhat they record and if they can be edited and what measures can be implemented to check18:21
daftykinsso what are you studying and where?18:22
ali1234well the general answer is that no consumer computer systems have this level of protection18:22
brian_if you recal i was not specific about the O/S or the equipment18:22
diddledanwe're in #ubuntu-uk so we assume a linux of some kind18:23
ali1234yes, and in general, nothing stops you editing the logs on most computers, if logging is even turned on, which it often is not18:23
brian_but would a medical computer system have this level of protection18:23
ali1234it is more likely, but nobody here has ever used one, so we don't know18:23
brian_ok i accept that response18:24
diddledanaah, sweet affirmation. I shall rest easy now18:24
ali1234heh18:24
brian_lets say their was a dispute as to whether such a medical system carried out a scan18:25
brian_maybe you can see the level of questioning18:26
ali1234well there's two possible outcomes18:26
diddledanI vote to destroy the evidence18:26
diddledanpreferably with fire18:26
ali1234either they produce the scans, proving that the scan took place, and then they can scan you again and show that the new scan is the same as the old one18:26
brian_which are18:26
brian_or tey produce the logs18:27
ali1234either that or they can just destroy the logs and then say they never existed, because they have not publicly commited to the existence of logs18:27
brian_are but that would impact upon credibility18:27
diddledanfraud is awesome. I vote fraud!18:27
ali1234it might impact their credibility a bit18:28
diddledandaftykins: will you keep watch while I burn the lab down?18:28
ali1234but not enough to matter18:28
brian_that maybe difficult if logs were requested to determine if they did or did not run a scan18:28
daftykinsdiddledan: ok, let's get some cheap walkie talkies18:28
ali1234okay so not homework but now i am wondering if you are a conspiracy nut18:29
ali1234are you trying to get the government to admit they did a CT scan on an alien or something?18:29
daftykinsXD18:29
diddledanI swear my alter ego is Harley Quinn18:29
brian_i think it would be did they do a scan on daftykins18:30
ali1234bottom line is you can't prove this either way after the fact unless systems were put in place beforehand to allow it18:30
ali1234which there aren't, because i don't know any NHS website where they publish the hashes of their audit logs so that anyone can later verify them18:30
daftykinsi always like how quick the nuts are to attack me back18:30
ali1234and anyway, if they wanted to scan an alien they could just trn the logging off18:30
ali1234or use an unregistered CT scanner somewhere18:30
diddledanwat? unregistered medical equipment?!18:31
ali1234backstreet dentists18:31
diddledanhow is that even a thing?!18:31
brian_well its because of all the lose bolts that fit the left handed threads18:31
diddledanP.S. I'll buy your liver for 200£18:31
ali1234https://www.youtube.com/watch?v=CC4ROmnsL0o18:32
diddledanI miss brass eye18:32
daftykinshe's got a hammer!18:33
brian_this may not be NHS related!18:34
brian_i guess they will after BREIXT dont need any regulation18:39
zmoylan-pii think the last time they did a scan on daftykins they got the error 'non human lifeform' :-P19:02
diddledan"Have I Got News For You" facebooks: "Plans announced to test self-driving lorries on English roads next year after the successful trial of a rudderless ship by the Tory Party"19:03
daftykinszmoylan-pi: confidential records my posterior...19:07
zmoylan-piwell most thumb drives you find in back seat of a taxi are posterior based...19:07
diddledanhttps://t.co/muJ4DDoTOg19:10
ali1234that from today's telegraph?19:11
ali1234its a bit lefty for matt19:12
diddledanmaybe photoshopped19:13
ali1234no i just checked its real :)19:15
ali1234i haven't been following the news much recently but it must be going really bad if that's on the front page of the telegraph19:16
zmoylan-piirish passport office has been super busy with applications from uk19:17
daftykins:>19:17
zmoylan-pi100,000 in 2017, 65,000 in 2016...19:18
ali1234how many in 2015 and 2014 though?19:19
zmoylan-pidoesn't list those numbers, just a 44% increase over pre brexit levels... https://www.theguardian.com/politics/2017/jul/19/irish-passport-rush-demand-jumps-50-per-cent-since-brexit-vote19:21
ali1234but the vote was in 201619:21
ali1234half of the 2016 figure is post brexit too19:22
diddledanthe vote was june 2016 which means that only 3 months were in those figures19:23
ali1234hmmmm19:23
ali1234the whole article is really confusing with the way it presents the figures19:24
diddledan2017 means april 2016 to april 201719:24
diddledanotherwise those figures would be even worse, 10000 in just 8 months19:25
ali1234but wait19:25
diddledan100,000**19:25
ali1234"More than 100,000 Irish passports were issued in the UK in the first six  months of 2017, up from 65,000 last year"19:25
ali1234so 2017 means jan 2017 to date19:25
diddledanin that case jan 2016 thru june 2016 vs jan 2017 thru june 201719:26
zmoylan-pifor a small island, it's a lot19:26
ali1234but then it says "just over halfway through 2017 the passport service had already issued more than 500,000 passports"19:26
zmoylan-pithat's most likely renewals19:27
ali1234"In the four years to 2016, the service issued between 632,000 and 670,000 in an entire year."19:27
ali1234so they are issuing nearly twice as many as usual19:27
ali1234and only 20% of them are in the UK19:27
ali1234and applications from outside the UK have also doubled19:27
ali1234so what does it mean?19:27
zmoylan-pimight be a lot of uk folk in eu with an option for an irish passport exercising that option19:28
diddledanor british living in ireland19:29
ali1234very possible19:29
zmoylan-piyes, we are part of the eu :-)19:29
ali1234british in ireland would be more likely to have irish ancestry, and also more use for an irish passport19:30
klystronit means Brexit is Brexit the UK is leaving the EU the Maybot has say so!19:30
ali1234so that makes sense19:30
zmoylan-pifor a long time using a uk passport was considered least hassle passport for working abroad19:30
diddledanyeah, we ducked that up, didn't we19:30
ali1234zmoylan-pi: relative to what though?19:30
diddledaneveryone19:31
zmoylan-piamerican passports were once gold standard till terrorism in 80s meanst they were victim #119:31
ali1234yeah but you don't have the option of any passport you want...19:31
zmoylan-piif you are wealthy there are ways19:31
diddledanget an illegal one19:31
zmoylan-pimost countries have ways of buying a passport legally19:31
klystronis Boris J now whistling for the divorce bill?19:32
diddledannot as if it'll get you in trouble19:32
zmoylan-pijust invest $$$19:32
diddledanlol: https://t.co/4rUdKwHfQF19:32
klystron I cant hear any whistling only the EU clock ticking away - the cliff edge is getting closer19:33
zmoylan-pithat'll be sold to the chinese for their uk theme park...19:33
klystronbut with self driving cars it will morph into a plane so wont crash over the cliff edge - oh it will not be able to fly in the EU free air space since we will no longer be members - all flights from the UK will be grounded LOL19:35
ali1234i dont think that is how it works19:36
zmoylan-piwe'll get the scots to finish hadrians wall so it encloses england... :-P19:36
klystronmy home work lol19:36
klystroni think so have a look19:36
ali1234SES hasnt been implemented yet because they can't agree the details19:37
zmoylan-pipretty much any solution will be cocked up by northern ireland border19:38
