charl_good morning10:00
charl_Maaz_: coffee on10:00
* Maaz_ puts the kettle on10:00
Maaz_Coffee's ready for charl_!10:04
theblazehenhey charl_ 10:18
theblazehenhey smile 10:18
charl_hi smile 10:19
charl_hi theblazehen 10:19
charl_theblazehen: did the server come back up ?10:19
theblazehencharl_, nope :(10:19
theblazehenGot DDOS'd 10:19
charl_oh but then it wasn't related to dns, was it ?10:19
theblazehenprovider can only give new IP on moday10:19
smilehi ! :)10:19
theblazehennope, not dns10:20
theblazehenDDOS started within minutes of us changing DNS...10:20
charl_theblazehen: the place where i work got ddosed with a 20gbps peak over the december holiday10:20
theblazehencharl_, damn...10:20
charl_theblazehen: fortunately our external capacity is twice that at 40gbps but the core router got unstable10:20
theblazehenlol10:20
theblazehenHaha, our idiots were doing udp port 8010:21
theblazehenlike, why not TCP ?10:21
charl_udp? so you can filter out udp packets? nice10:21
charl_yeah udp is easier for idiots10:21
theblazehencharl_, you can filter them?10:21
theblazehenah10:21
charl_these days you get these dns reflection attacks or ntp spoof attacks10:21
theblazehenyeah, all UDP those10:22
theblazehenBut TCP port 80 would probably kill web server10:22
charl_the isp should be able to filter those out at a higher level10:22
theblazehenwhich was the target10:22
charl_that would make filtering harder10:22
theblazehenoh, well hosting company is shit... so.10:22
charl_but you need to go and do deep packet inspection10:23
charl_there are probably some other attributes too that you can filter out10:23
charl_in case it was tcp10:23
charl_guys like cloudflare are good at mitigating ddos10:23
theblazehenyeah10:23
charl_but if they know the ip behind cloudflare you're toast10:23
theblazehenwe were moving DNS over to cloudflare when DDOS started...10:23
charl_so you have to hide that ip really well10:23
charl_well both dns and their reverse proxy you will need10:24
theblazehenyeah10:24
charl_and don't enable the direct. subdomain10:24
charl_because then they can find your real ip again :)10:24
charl_i was surprised when cloudflare enabled that by default10:24
theblazehen"." subdomain?10:24
charl_they should warn10:24
charl_let's say you enable example.com then they create direct.example.com pointing to the original ip10:25
theblazehenyea10:25
charl_you can disable that by removing the entry on cloudflare10:25
charl_otherwise they can find your original ip address easily10:25
theblazehenah, yes10:26
theblazehenBBIAB, shortening my ethernet cable10:26
charl_lol10:27
Kiloshi all10:48
Golynxhi Kilos10:50
GolynxGuess what i did yesterday, to solve that issue of something that cost me 70MB of data10:51
Kiloswhat was it?10:51
Kilosi gotta go eat10:52
Kiloswbb10:52
Golynxspent all day in the main #ubuntu channel trying to figure out what was caussing it 10:52
Golynxok10:52
charl_hi Kilos 13:42
Kiloshi charl_ 13:42
charl_:)13:46
charl_roomba busy cleaning the house agaion13:46
charl_*again13:46
Kilos:-)13:46
charl_while i sit and watch tv :P13:46
Kiloshaha13:46
charl_actually not a tv, just an external screen connected to my laptop13:46
charl_iptv ftw :)13:47
psydroid1hi charl_ 13:52
psydroid1hi Kilos 13:52
Kiloshi psydroid1 13:52
psydroid1oh13:52
=== psydroid1 is now known as psydroid
charl_hi psydroid 13:53
Golynxhi charl_ and psydroid14:02
GolynxSo Kilos did you guess what the issue was ?14:12
Golynxhi Xethron14:13
Kilosno14:13
GolynxI was lucky that someone from #ubuntu helped me to track down that process that was eating my data14:14
Kiloshave you written down how to track it14:15
Kilosand what was it14:15
Golynxwe found the process id of the culprit and was able to find the location and program that was responsible14:15
Kilosgood and what was it14:16
GolynxClamav was constantly downloading new virus definitions every 30 minutes14:16
GolynxI never installed it 14:16
psydroidhi Golynx 14:17
psydroidhi Xethron 14:17
Kilosmust have been part of what i had installed14:18
GolynxThere was no mension of Clamav in the programs list or anywhere, to help me configure it to another update time. So i searched for it in Synaptic and removed every single trace of it 14:18
Kilosyou can remove clamtk and clamav14:18
Kilosgood14:18
GolynxFreshclam came up at the process id time of the search, but freshclam is the update helper for clamav  14:19
GolynxI didnt knew what it was until that guy told me its an antivirus program14:20
Golynx70MB gone to waste. Only 20 left till the 15th 14:20
Golynxbut ya its ok i will live14:22
Kilosweird it used so much14:25
Kilosfreshclam updates are minimal14:25
Kilosi have it running here to check emails from dubious places\14:27
GolynxAt times when i wasnt looking at itop i caught it downloading around 15MB of stuff. 14:27
Kiloswow14:27
Kilosya then better removed14:28
Golynxhad to disconnect to stop it, but it came back every 30 minutes14:28
Kilosjust freshclam removal should stop that14:28
Trixar_zaOo14:29
GolynxI dont want antivirus programs now, maybe in the future when i got a reason to have them 14:29
Trixar_zaYeah, it's kind of a waste14:29
somaunnhi Kilos14:30
somaunnhi nuvolari14:30
somaunnhi Squirm14:30
somaunnhi Golynx14:30
Trixar_zaLinux can't get Windows viruses (only spread them if you forward an infected mail to someone)14:30
Golynxhi Trixar_za14:30
somaunnhi nlsthzn_14:30
Kiloshi somaunn 14:30
Kiloshi Trixar_za 14:30
GolynxHi somaunn14:30
Trixar_zaAnd the handful of active Linux ones (around 40 if memory serves), most can only do damage if you give it permission to do so.14:31
Trixar_zaHey Golynx, somaunn and Kilos14:31
Trixar_zaHalf the reason I don't like Puppy's root-by-default thing14:32
GolynxYa Trixar_za thats true. If it was windows i wouldve kept it, had Avira antivirus on that one. 14:33
Trixar_zaI think Avira makes a Linux version now, but it's similiar to Flash - it's precompiled and closed source14:36
GolynxThats good , maybe some people will use it.14:38
Kiloshi theblazehen 14:45
theblazehenhey Kik14:45
theblazehenKilos*14:45
Kiloshehe14:45
Golynxhi theblazehen14:47
theblazehenhey Golynx 14:48
theblazehenbrb14:49
Kiloshey Golynx what would you send the 11.3 kb/s signal through to kill mosquitos14:49
Kilosspeaker?14:49
KiloskB/s14:51
Golynxthe frequency that drives them away is between 30 and 40Hz . Its usually sent through a speaker 14:52
theblazehenGolynx, whats that?14:54
Golynxits best to oscillate in that frequency range , since picking one frequency wont be successfull14:55
Golynxtheblazehen: its a sonic insect repeller14:55
Kilosi have a sig gen that i can experiment on i just wondered what to send it through14:56
Kilosone site onle showed some thing in a glass tube14:56
Golynxyou need a vibrating mechanism to achieve such a sound frequency14:58
Kilosand i hink the frequency they gave was 11.3 kB/s14:58
Kilosill try find it14:59
Golynxspeakers is the general tool for that14:59
Golynxhmm that must be in the electronics14:59
Kilosthats great i can vary frequency from 0 to 30meg15:00
Golynxthe generated sound is in Hertz15:00
Golynxok good15:01
Kilosgotta find the frequency counter too so i know what is where15:03
GolynxI just need 2 NPN transistors , 2 100UF capacitors , 2 10k OHM resistors , a high frequency speaker and a 9 volt or 6 volt battery15:04
Kilosover 30 year old pieces of equipment15:04
Golynxthat is enough to make any dog run and weee at the same time :)15:04
Kiloslol15:04
Kilosyou wanna chase dogs or mosquitos?15:04
Golynxlol nope , but dogs can hear that same range of frequencies the mosquitos do15:05
Kilosah15:06
GolynxThat will do perfectly , if you know how to 15:06
Golynxi built the same little circuit 20 years ago with only 6 components and worked great15:07
Golynxbut you gotta use a variable resistor, like the volume dial on a radio, to run through the frequencies and set the right one to drive the insects off15:08
Kilosmail me the circuit diagram lemme try it , got lotsa eletronic spares15:09
Kilosya i got pots and everything15:10
Kilosand maybe even some varicaps orund somewhere15:10
Golynxthats great, i remember how the circuit was layed out , its just the values of the components and type of transistor that i dont remember. 20 years ago i used to go to the library and found that in a book Sam's guide to electronics , was in versions 1,2 or 3. I think 2 . But i will find out if its available on the web. Its very easy to build though15:16
Kiloscool15:17
Kilosi need something that can chase midges and white fly. they bite me but no one else here15:17
somaunnKilos: they are maybe MS spies15:20
Golynxoh thats bad15:20
Kiloslol15:20
Golynxlol15:20
Kilosyeah they are so tiny one can hardly see them but the bites are eina15:20
somaunnKilos: need to look carefully and check if they've got sort of flag on them or not15:20
Kiloshaha15:21
somaunncan we talk network security ?15:21
Kilosya15:22
Kiloswi15:22
somaunni really it but don't really have big knowledge and in the same time i'm deeply impressed of peoples really doing that15:23
theblazehensomaunn, what about it?15:23
somaunnwant to understand where are we going with network security15:24
Kilosif you have a problem with something explain what the prob is and wait for one of the experts to see it15:24
somaunni mean, we all know it's important to have good politic regarding the security of our network but in the real world what does it mean ?15:25
Kilosremember somaunn is french guys so explain things nicely15:28
GolynxKilos would you know what the real components look like when viewed from a diagram15:34
Kilosi know what components look like. just need to know the diagram with what connects where15:35
Golynxthats good , i found this , it has some good examples you can test from www.sentex.ca/~mec1995/tutorial/xtor/xtor7/xtor7.html15:36
Golynxthats good , i found this , it has some good examples you can test from http://www.sentex.ca/~mec1995/tutorial/xtor/xtor7/xtor7.html15:36
Kiloswas an electronics tech 40 years ago15:36
Kilosty15:37
GolynxNice it was fun being in that field back then, little to worry about. Until the IC came and made it boring 15:38
KilosIC?15:39
Kilosoh ya15:39
Kilosmade lots of things simpler and faster15:39
GolynxIntergrated Circuits15:39
Golynxor microchips15:39
Golynxya true15:39
Kiloshard work trying to make trannies resistors and caps do the same work15:40
Kilosthose ic's from then were lekker to work with you could solder them in yourself. now they have so many pins you cant get a soldering iron small enough15:41
Golynxlol ya , i built a cb radio reciever with a 555 chip i think it was, had only 16 pins15:43
Kiloslol15:45
GolynxHere is a good one too http://www.allaboutcircuits.com/worksheets/oscill.html15:45
Kilosi still have a cd radio in the storeroom somewhere15:45
Golynxhaha ya amatuer radio was fun back then15:46
Kilosi dont want to learn about the stuff again. eye not good enough to do fine work15:46
Kilosi have a yaesu ft 200 as well15:47
Kiloswb theblazehen 15:48
Kiloshi nlsthzn 15:48
GolynxIf you already have a oscillator or multivibrator you can use that and just couple a high frequency speaker to it  15:48
Golynxhi nlsthzn15:49
nlsthznaloa ll15:49
nlsthznerm15:49
nlsthznalo all15:49
theblazehenwhat happened? lol15:49
theblazehenty Kilos 15:49
Kilosi have a belco sg 2030 signal generator that you can vary15:50
Kiloseven has rf out sockets15:50
Golynxgreat thats perfect15:51
Kilosso speaker plugged in there should work15:51
Kiloshave an amp somewhere as well so i could maybe push out 100 watts or more15:52
Kiloschase every noonoo in the surrounding district\15:52
Kiloshows nlsthzn 15:53
Golynxat the frequency you have to output the sound will bounce off the walls it wont reach other rooms15:53
nlsthznI am ok thx15:53
Kiloswell thats good too as long as the bugs stay away from me15:54
Golynxso its best to have noting blocking the output of the generator15:54
Kilosya15:54
Golynxya let them crawl back to MS 15:55
Kiloslol15:56
Kilosthey fly15:56
Kiloscrawlies you can stomp15:57
Golynxeven the fly will start crawling , else it will be too dizzy to fly15:58
Golynxi regret abusing the neighborhood dogs now, for killing their eardrums 20 years ago lol16:00
Golynxbut was fun to see them run and scream :D16:01
Kiloslol16:07
magespawngood evening17:03

charl_i magespawn 17:09
charl_hi17:09
Kiloshi magespawn 17:10
Golynxhi magespawn17:11
Kilosoh charl_ another prob with too much off topic is that someone could have asked for help or something and its too much hassle to scroll back and see the days stuff so they dont get helped or whatever17:12
Kiloslike the pro dont even scroll back anymore17:13
charl_Kilos: i'm not saying it is a bad idea, the other countries also have similar splitting17:14
charl_Kilos: but if we do it let's do it officially then17:14
magespawnhi charl Kilos Golynx 17:14
charl_Kilos: i think it's a great topic for the next meeting17:14
charl_Kilos: then let's take a vote and get a decision on it made17:14
Kilosadd it to agenda then17:15
somaunnhi Kilos17:15
charl_Kilos: how do we do that?17:15
Kilosi dunno whats involved in getting official channels with buntu17:15
somaunnwas a bit far from my desk17:15
magespawnhi somaunn 17:15
Kiloshttp://bit.ly/19ZrMER 17:16
somaunnhi magespawn17:16
magespawnmaybe we can ask one of the higher ups17:16
charl_that's the page yes but how do we add items onto it17:16
Kilosthere was a button or something17:16
charl_all the items there are by nuvolari17:16
charl_i don't see anything17:17
Kilosor tick on the last thing and an add option comes up17:17
magespawnyou have to login on the top right hand side very small17:17
charl_nuvolari: you there?17:17
charl_bah i have to have an account on ubuntu one for it?17:17
charl_i had an account but i think it was under an old address17:17
magespawni do not think that it is an ubuntu one account, i think this is run by superfly from a servers at uct or some such17:21
charl_no this is on loco.ubuntu.com that looks official17:22
charl_and when i click log in i get an ubuntu one thing17:22
magespawnso i see, i must have that cat by the tail then17:25
charl_lol17:25
charl_that is quite a good unix joke :)17:25
charl_first time i hear it now17:25
magespawnhow is that a unix joke?17:41
* Kilos was also wondering17:41
magespawnfirst time i heard it, was in afrikaans17:41
Kiloswhew whats unix in afrikaans17:43

Kiloshave not sold it all before19:07
charl_very tasty19:07
inetpromaybe it will grow, maybe not 19:07
Kilosmain spice in boerewors too19:07
Kilosit grows very well in rustenburg19:08
magespawna general question, could you do this: mtr xxx.xxx.xxx.xxx | filename ?19:08
inetprotoo much of it in boerewors spoils the taste of the meat 19:08
Kilosna man19:08
Kiloswhere you heard that19:08
inetpromagespawn: why? 19:08
magespawnwhen you close mtr the results close too19:09
inetproor rather, no why? 19:09
magespawnto keep a record to show someone else19:09
magespawnlol19:09
charl_magespawn: you have to use a special flag, one sec19:09
charl_This option puts mtr into report mode.  When in this mode, mtr will run for the number of cycles specified by the  -c  option,  and then print statistics and exit.19:10
charl_-r19:10
inetprothere's an option for running it without interactive mode 19:10
inetpro^19:10
