| ignatius_ | ok. stupid question, I just upgraded to the latest version of OpenWRT. and for the life of me, I can't figure out how to get networking working. i'm using the ks7010 micro sd card. before, all I had to do was "iwconfig eth0 essid any; dhclient", now that doesn't seem to work. anyone have any ideas why? | 00:33 |
|---|---|---|
| kristianpaul | may be kyak but i think he is sleeping now | 00:34 |
| kristianpaul | arghh, i forgot clock domain syncs.. | 01:21 |
| kristianpaul | i wonder how sane routing clock domain sync will be having all 12 chanells.. but lets try with one first | 01:22 |
| wpwrak | ignatius_: i'd suggest to ask on the mailing list. kyak is a well-known owner of two such wlan boards, but he has troubles with both (hardware issues are suspected), so he may not be able to help you much. | 01:28 |
| kristianpaul | what a mess, this should be in both ways.. | 01:36 |
| kristianpaul | be done* | 01:37 |
| kristianpaul | anyway.. | 01:37 |
| wolfspraul | well, but ignatius_ sounds like he had this working before, and now it stopped | 01:49 |
| wolfspraul | software regressions, which may also be behind the problems kyak sees? | 01:50 |
| wpwrak | wolfspraul: yes, that could explain things. it's a friendlier explanation than really bad QA :) | 01:53 |
| ignatius_ | yeah. I did have it working before. | 01:56 |
| ignatius_ | with the Debian root image, though. | 01:56 |
| wpwrak | hmm. that promises to get interesting :) | 01:57 |
| ignatius_ | when I execute a "iwlist eth0 scanning" it detects a few wifi hosts.. but when I execute dhclient, it doesn't do anything. | 01:58 |
| ignatius_ | so.. is dhclient the problem? that's what i'm wondering. | 01:58 |
| wpwrak | ignatius_: are any of the hosts open (unencrypted) ? | 01:58 |
| kristianpaul | good question :-) | 01:59 |
| ignatius_ | maybe, if i examine the /etc/init.d files in the Debian OS pertaining to networking, i'll get an answer.. | 01:59 |
| wpwrak | ignatius_: naw, iwlist scan should tell you this | 01:59 |
| ignatius_ | well, I have my own wireless router... | 01:59 |
| ignatius_ | but, yes, there are 2 unencrypted hosts. | 02:00 |
| kristianpaul | you did iwconfig eth0 essid wifinetname | 02:00 |
| kristianpaul | ? | 02:00 |
| kristianpaul | before dhclient? | 02:01 |
| wpwrak | wolfspraul: that thingy does support WPA, doesn't it ? (every once in a while, you can find an ancient chip that doesn't) | 02:01 |
| ignatius_ | yes. | 02:01 |
| Last message repeated 1 time(s). | 02:01 | |
| wpwrak | ignatius_: (unencrypted) perfect. then you can try to associate to them | 02:01 |
| kristianpaul | ignatius_: if so can you skip then dhclicnet and just configure ips manually so it should work this way too i think | 02:02 |
| ignatius_ | well, I have two NanoNotes.. one with OpenWRT, and another with Debian. the Debian machine works flawlessly. | 02:02 |
| wpwrak | ignatius_: iwconfig should show you if the association works ("Access Point:" shows a MAC address) | 02:02 |
| ignatius_ | you mean "Address:" ? | 02:03 |
| wpwrak | ignatius_: dunno. this is what iwconfig output looks like on one of my PCs (not a ben): http://pastebin.com/sqYVpcNH | 02:05 |
| wpwrak | ignatius_: the AP's MAC address would be after "Access Point:" | 02:05 |
| wpwrak | ignatius_: otherwise, i think it says "not associated" | 02:05 |
| ignatius_ | hmm. | 02:06 |
| wpwrak | ignatius_: maybe just paste the iwconfig output :) | 02:06 |
| ignatius_ | well, there is a hexidecimal string after "Address:" on my machine. | 02:06 |
| ignatius_ | is there a way to skip the dhclient step and set up the networking another way? | 02:07 |
| kristianpaul | ifconfig ? | 02:08 |
| ignatius_ | i'm not too knowledgabe on wireless mechanics in Linux. | 02:08 |
| kristianpaul | is same as ethernet | 02:08 |
| ignatius_ | ifconfig.. iwconfig.. whichever | 02:08 |
| kristianpaul | hum | 02:08 |
| kristianpaul | what ip adressing your acces point implements? ie 192.168.0.xxx | 02:09 |
| kristianpaul | what is your gateway | 02:09 |
| kristianpaul | ? | 02:09 |
| wpwrak | ignatius_: first of all, the access point you're now associated with, it this your own or somebody else's ? | 02:10 |
| kristianpaul | ;-) | 02:10 |
| wpwrak | ignatius_: i.e., do you know its configuration ? | 02:10 |
| kristianpaul | are yoy already connected to it? | 02:10 |
| ignatius_ | it's my own. | 02:10 |
| ignatius_ | not with the NanoNote. | 02:11 |
| kristianpaul | with your laptop, so that can tell us the netowrk configurarion easylly runnning ifconfig on that machine that is connected | 02:11 |
| ignatius_ | although, the "wavmon" utility shows that it is connected. | 02:11 |
| wpwrak | ignatius_: hmm, so your laptop is associated with your access point but your ben isn't ? | 02:11 |
| ignatius_ | yes. | 02:12 |
| wpwrak | ignatius_: or are both associated but only the laptop has TCP/IP working ? | 02:12 |
| ignatius_ | that is.. I can connect to the network with every machine but the NanoNote running OpenWRT. | 02:12 |
| wpwrak | ignatius_: can you paste the output of iwconfig from your laptop ? e.g., on pastebin.com | 02:13 |
| ignatius_ | hmm. good question. not sure if networking is working... | 02:13 |
| ignatius_ | my desktop machine? | 02:13 |
| ignatius_ | or the NanoNote with Debian? | 02:14 |
| wpwrak | ignatius_: the laptop you said is associated with your access point | 02:15 |
| ignatius_ | hmm... it just occured to me... maybe I have to do a "init 3" ??? | 02:15 |
| ignatius_ | hold on a sec | 02:15 |
| wpwrak | ignatius_: we'll get to the ben later. first i want to see what your laptop is doing | 02:15 |
| ignatius_ | thanks, BTW. | 02:16 |
| qi-bot | [commit] Werner Almesberger: tools/usbperf/: measure the rate of control transfers a device can do (master) http://qi-hw.com/p/ben-wpan/97604d7 | 02:17 |
| ignatius_ | bleh. now my laptop is refusing to connect. | 02:21 |
| ignatius_ | i'm going to reboot. maybe that'll help. | 02:21 |
| wpwrak | success !! now the ben is as good as the laptop ;-) | 02:21 |
| wolfspraul | I think in theory it does support WPA, yes | 02:37 |
| wolfspraul | but I don't know much about it, never used it | 02:38 |
| ignatius_ | ok. I got an "Access Point" | 02:50 |
| ignatius_ | on the NN | 02:50 |
| wpwrak | great ! | 02:50 |
| wpwrak | now, does dhcp work with it ? | 02:51 |
| ignatius_ | when I start dhclient.. it just hangs there. | 02:52 |
| wpwrak | can you paste the output of iwconfig (on the ben) ? | 02:52 |
| wpwrak | (e.g., on pastebin.com) | 02:53 |
| ignatius_ | it just locked up.. hold on. rebooting | 02:53 |
| ignatius_ | http://pastebin.com/DXN63cfj | 03:19 |
| wpwrak | ignatius_: looks great | 03:29 |
| wpwrak | ignatius_: does dhclient -d eth0 say anything interesting ? | 03:31 |
| ignatius_ | that did it. :) | 03:34 |
| ignatius_ | although, it doesn't fork into the background. | 03:35 |
| reuben | the -d flag does that | 03:39 |
| ignatius_ | ah. | 03:41 |
| ignatius_ | thanks for the help, wpwrak. | 03:48 |
| kyak | heh yeah, my problem is that 'iwlist scanning' doesn't even return anything | 06:31 |
| kyak | it says "no data" | 06:32 |
| kyak | i guess it might be hardware issues, as wpwrak mentioned | 06:32 |
| qi-bot | [commit] kyak: qball: patches went upstream, updated to 1.3 (master) http://qi-hw.com/p/openwrt-packages/3b735b0 | 08:29 |
| CapnKernel | Hello and welcome from sunny Shenzhen | 12:39 |
| CapnKernel | I just got back from a meeting of the Shenzhen Linux User's Group, where I heard some great talks, and spoke with a fantastic group of like-minded geeks about starting a hackerspace here. | 12:40 |
| lekernel | :) | 12:42 |
| wolfspraul | CapnKernel: great. tell them a bit about the Ben NanoNote and Milkymist One too ;-) | 12:42 |
| CapnKernel | Oh, they told me! | 12:43 |
| wolfspraul | for Ben NanoNote I'm sure they've heard about it before, because we have/had some quite active guys in szlug | 12:43 |
| wolfspraul | yes, there you go :-) | 12:43 |
| CapnKernel | They know all about Qi hardware | 12:43 |
| wolfspraul | but maybe they don't know Milkymist One yet | 12:43 |
| wolfspraul | which is a far more serious hacker tool than the Ben | 12:43 |
| wolfspraul | you can fly to the moon with m1 :-) | 12:43 |
| CapnKernel | They didn't mention m1 | 12:43 |
| wolfspraul | yes. so you need to evangelize... | 12:44 |
| CapnKernel | I would except that I don't know it either | 12:44 |
| wolfspraul | free CPU, super powerful programmable visuals and fpga etc. | 12:44 |
| wolfspraul | www.milkymist.org | 12:44 |
| wolfspraul | the world's most powerful and most free CPU/SoC | 12:44 |
| wolfspraul | CapnKernel: what did you learn from them? | 12:45 |
| CapnKernel | That there is something very universal about being a geek :-) | 12:45 |
| wolfspraul | btw, watch your safety in Shenzhen. it's probably the city with the most street crime in China. | 12:45 |
| CapnKernel | And about being a hacker | 12:45 |
| CapnKernel | wolfspraul: Thanks | 12:45 |
| wolfspraul | it's a seriously wild place | 12:45 |
| CapnKernel | I'm told it's the place that Guangdong folk point to, and say "that's a wild place". | 12:46 |
| wolfspraul | you must be careful with your purse, any bag you have around you etc. | 12:46 |
| CapnKernel | (And Guangdong has the reputation as China's wild place) | 12:46 |
| wolfspraul | wallet I mean, not purse :-) | 12:46 |
| CapnKernel | I don't know, I found one that suits my suits just nicely. | 12:46 |
| CapnKernel | Sorry, suits my shoes | 12:46 |
| wolfspraul | well I've told you - be careful there | 12:47 |
| wolfspraul | they are very fast, they work in teams, they bribe local security etc. | 12:47 |
| CapnKernel | Yes you've told me, and I wouldn't be surprised if something happens. | 12:47 |
| wolfspraul | I'm speaking from experience... | 12:47 |
| CapnKernel | I believe you | 12:47 |
| wolfspraul | no but you have to be faster/more alert than they are, that simple | 12:47 |
| wolfspraul | China survival | 12:47 |
| CapnKernel | I look out for distractions | 12:47 |
| CapnKernel | Things that can take your eye off what's important | 12:48 |
| CapnKernel | Like somebody dropping something | 12:48 |
| wolfspraul | just keep anything valuable super close to your body, best in front etc. | 12:48 |
| CapnKernel | Noted | 12:48 |
| wolfspraul | yes, binding their shoelace | 12:48 |
| CapnKernel | Bit hard when you've got a computer on your back | 12:48 |
| wolfspraul | I was never impressed with the quality of hackers I found there, in the end. | 12:49 |
| wolfspraul | although, in their favor, it's extremely hard to be a good hacker from mainland china | 12:49 |
| wolfspraul | the so called great firewall is crazy, it totally blinds you, excludes you | 12:50 |
| wolfspraul | so probably they have no chance, until they take that piece of shit down | 12:50 |
| CapnKernel | One guy showed me a phone he'd made for his grandmother. She can't see, and certainly can't dial numbers. The phone has a large 4x4 keypad, with each key being a different person. She presses one button, it dials that person. | 12:50 |
| wolfspraul | that's nice | 12:50 |
| wolfspraul | snap a picture... | 12:51 |
| CapnKernel | He had an atmega32 in there, line interface circuit, standard phone tx/rx chip, was doing dtmf generation in software, etc. Very very hackerish, very very improve society. That's what it's all about | 12:51 |
| CapnKernel | These guys are ready | 12:52 |
| CapnKernel | Seems most of them use VPNs and are well versed in getting what they need to know from wkp. | 12:52 |
| CapnKernel | For example, these guys know who Bunnie Huang is, and know what he's done. | 12:54 |
| CapnKernel | (BTW I have been speaking with Bunnie) | 12:54 |
| wolfspraul | no I stand by my assessment | 12:57 |
| wolfspraul | there is no quality there :-) | 12:57 |
| wolfspraul | and the firewall does have grave consequences and seriously limits even the talented guys | 12:58 |
| wolfspraul | if werner would be inside the firewall for too long he would become a mountain terrorist, for sure | 12:58 |
| wolfspraul | it's 'thought crimes', committed every day, thousands of times | 12:58 |
| wolfspraul | CapnKernel: next time you see an interesting hardware hack (like that phone), remember you take a picture and write a short blog post about it | 12:59 |
| wolfspraul | they will seriously be happy and it will help everybody | 12:59 |
| CapnKernel | I know what you're saying. | 13:00 |
| CapnKernel | Specifically about the phone, and cool projects, I'd rather THEM write about it, in their own words, so they develop their own compulsion to share. | 13:00 |
| wolfspraul | the effects of the firewall are slow (it's designed to function like that) | 13:00 |
| CapnKernel | Information is power. | 13:00 |
| wolfspraul | ok, then we can wait forever | 13:01 |
| wolfspraul | so the firewall will slowly, little by little, drive people to give up | 13:01 |
| wolfspraul | give up wordpress.com, give up watching interesting stuff on youtube, give up wikimedia commons, give up blogspot, give up twitter, and so on | 13:01 |
| wolfspraul | you have to take the picture, and you have to blog about it. otherwise nothing will happen, quite simple. | 13:02 |
| CapnKernel | wolfspraul: I know what "learned helplessness" is. | 13:03 |
| CapnKernel | http://en.wikipedia.org/wiki/Learned_helplessness | 13:03 |
| CapnKernel | wolfspraul: What time you arriving? | 13:04 |
| wolfspraul | I disagree. you have to reach out and help them by bridging the gap first. even if that leads nowhere, at least a few people may see your example and one day remember. | 13:04 |
| wpwrak | there was life on earth before the internet :) but yes, once you're used to it, it's hard to get by without | 13:04 |
| wolfspraul | bullshit about 'learned helplessness' when you have the world's most sophisticated censorship and propaganda machine around you since birth | 13:05 |
| wolfspraul | you have to help them, and decisively. by giving an example. | 13:05 |
| wolfspraul | wpwrak: that firewall would drive you nuts, I know it :-) | 13:06 |
| wolfspraul | especially how it is done, he | 13:06 |
| wolfspraul | the sllooooooooooow poision | 13:06 |
| wolfspraul | so slow it's unnoticable | 13:06 |
| wolfspraul | but with dramatic effects over time, especially on hackers | 13:06 |
| CapnKernel | wolfspraul: I really appreciate your advice, but I think we're done now. | 13:10 |
| wolfspraul | looking forward to your findings, keep us posted | 13:10 |
| wolfspraul | you plan to open a hackerspace there? | 13:11 |
| wolfspraul | will it have a website? | 13:11 |
| wolfspraul | and yes, I'm definitely curious to see a picture of that phone, hopefully one day... | 13:12 |
| CapnKernel | I plan to use my experience to help them open their own hackerspace. | 13:16 |
| wolfspraul | good. the more they have a chance to interact with you, personally, the better for them. | 13:17 |
| wolfspraul | I was there many times, but now I focus on what I've learnt :-) | 13:17 |
| wolfspraul | getting selfish, he... | 13:17 |
| wolfspraul | just thinking. shenzhen is not too far from hong kong. could you setup some sort of high-speed direct link to HK? | 13:20 |
| wolfspraul | many some powerful and directed antennae? | 13:21 |
| wolfspraul | the hackerspace wouldn't stand too long, but it'd be a really cool project | 13:21 |
| wolfspraul | s/many/maybe/ | 13:21 |
| wolfspraul | I recently found out about fabfi.fablab.af and guifi.net, very cool projects imho | 13:23 |
| wolfspraul | the extension for ben-wpan :-) | 13:23 |
| CapnKernel | What would a high speed link do? | 13:25 |
| CapnKernel | I have told them I'm here three months for investigation, with the option of a few years if it looks good. | 13:25 |
| CapnKernel | Having the hackerspace provide communication services is a dumb thing, as it then makes the organisation a target for attention. | 13:26 |
| lekernel | it's a waste of time, too | 13:26 |
| CapnKernel | These guys know how to get what they want, and each can deny knowledge of what the others do, should there be a problem. | 13:26 |
| lekernel | any geek can run a server in their garage, there's no need for a hackerspace for that | 13:27 |
| CapnKernel | keep the surface area of a potential target as small as possible | 13:27 |
| CapnKernel | I'll be back later | 13:27 |
| lekernel | hackerspaces should be for large CNC machines, semiconductor labs, etc. | 13:28 |
| lekernel | most other uses are boring | 13:28 |
| CapnKernel | lekernel: You may be conflating the idea of a place, with an organisation. | 13:29 |
| CapnKernel | It's great to have a place to keep larger stuff. But an organisation can still work with people carrying their own stuff. | 13:29 |
| CapnKernel | What we've found in Melbourne is that the value of a hackerspace is not just in the technical sharing, but the social aspect. | 13:31 |
| CapnKernel | Coming together to share reinforces the idea. | 13:31 |
| lekernel | oh, yeah, but I've seen too many hackerspaces becoming pure social spaces | 13:32 |
| lekernel | socializing is nice, but it's not what hacking is all about | 13:32 |
| CapnKernel | I will try to help with what I have learned from my experience in Melbourne. | 13:33 |
| lekernel | if you just want a meeting point, you can do something like 2600 meetings | 13:35 |
| lekernel | easy to set up | 13:35 |
| kristianpaul | oh, to kernels i tought i never will saw something like that ;) | 13:43 |
| kristianpaul | hello CapnKernel | 13:44 |
| kristianpaul | I agree with lekernel said, hackerspace is for big stuff (hopefully expensive too) that need to be place on a common place | 13:44 |
| kristianpaul | the rest can stay at home, | 13:45 |
| kristianpaul | I pointed expensive because that make you look for more people and buy/build it together somethimes | 13:45 |
| kristianpaul | s/saw/see | 13:49 |
| wpwrak | kristianpaul: like "it's too heavy for a single person to move" ;-) | 13:53 |
| kristianpaul | yes | 13:53 |
| CapnKernel | Some of the hackerspaces in Australia have laser cutters and lathes. They are good candidates for putting in a hackerspace. | 14:30 |
| qi-bot | The build was successfull, see images here: http://fidelio.qi-hardware.com/~xiangfu/compile-log/openwrt-xburst.full_system-07092011-1130/ | 15:12 |
| kristianpaul | wpwrak: may be you already checked this but your troughput problems with atusb is not maybe about a buffer limitation in the atmega side? | 22:38 |
| kristianpaul | well, i remenber same experience with burst transfer using microchip mcu and i remenber conclusion was around that | 22:41 |
| wpwrak | kristianpaul: naw, i think i understand it now. it's a limitation of how the UHCI works. need to write it up. | 23:51 |
