16:36.54lufmerlin1991: ping
16:37.40merlin1991luf: pong
16:38.05lufmerlin1991: I'm not able to ssh to merlin1991.at :(
16:38.12merlin1991what does it say?
16:38.25lufmerlin1991: is the problem on my side? It says nothing ...
16:38.31merlin1991I get in
16:38.52lufConnection closed by 188.40.39.11
16:39.41merlin1991odd
16:39.46merlin1991let me check hte logs
16:40.25merlin1991luf: nothing there about even a logon attempt
16:41.43lufHmmm. Ok.
16:43.37kerioohai luf
16:45.29lufkerio: hello :)
16:45.48lufStrange I'm there now.
16:45.58lufNothing changed.
16:46.02lufmerlin1991: ^^^
16:46.35merlin1991nettwork hiccup maybe?
16:47.12lufmerlin1991: seems so. I maybe should think about different provider.
16:52.10kerioluf: i can't get bt pan to work :'(
16:52.50lufkerio: what changed?
16:53.08kerioidk
16:53.20kerionothing
16:53.24kerio...weeeeeeeell
16:53.48lufDon't keep the change just for yourself. Let's share ;)
16:54.06kerioi did delete a bunch of packages, and i moved my /home to ext4
16:54.34kerioand right now, my Conversations show a scrollbar that i have to use to scroll
16:54.43lufWhat bt debug says about it?
16:55.00kerioluf: one sec, i'm re-pairing
16:55.03lufBT PAN shouldn't depend on any packages.
16:55.07kerioindeed
16:55.35freemangordonmerlin1991: meeting on Monday?
16:56.00kerioluf: what do you mean by bt debug?
16:56.05merlin1991freemangordon: yep
16:56.58lufkerio: bluetoothd -n -d '*' and syslog output
16:57.09kerioi see
16:57.19kerio...how am i supposed to do this? i can't use wifi :s
16:57.56freemangordonmerlin1991: do others know about it?
16:58.21lufkerio: terminal on N900 ? edit /etc/event.d/bluetoothd
16:58.38merlin1991Pali: ping
17:00.07Palimerlin1991: pong
17:01.06kerioluf: nothing wrong at all
17:01.16keriobut i'm still getting no route available/destination unreachable/timeout
17:01.32merlin1991Pali: got time monday evening?
17:02.19lufkerio: there has to be something in syslog when you try to connect.
17:02.20Palimerlin1991, I think yes
17:02.26merlin1991meeting then
17:02.33kerioluf: oh of course there is
17:02.39lufmerlin1991: ok
17:02.47lufkerio: pastebin?
17:03.26keriohttp://pastebin.ca/2316890
17:03.34kerioeverything seems perfectly fine
17:03.44kerioexcept that the packets aren't flowing
17:03.52merlin1991freemangordon: now everyone knows :)
17:04.33lufkerio: NAP on N900 and client is you computer, right?
17:04.37kerioyes
17:04.46lufifconfig -a ?
17:05.29kerioah fuck where's my ip
17:05.43luf:D That seems like the problem :D
17:05.53kerioi swear that there was the ip at some point
17:05.56kerioand it still didn't work
17:05.57luf/etc/network/interfaces?
17:06.08keriolike... right now
17:07.23lufifconfig -a ? netstat -rn ?
17:07.50lufdinner is calling me ...
17:08.14keriobtnap with its address, bnep0 up, bridge is correct
17:18.27lufkerio: ifconfig -a ? netstat -rn ?
17:18.44lufkerio: and what the opposite side? also ok?
17:19.34lufkerio: tcpdump ? hcidump ? (on both endpoints)
17:20.03keriorouting table is ok
17:20.19kerioalthough...
17:20.28kerioshould the route go for btnap?
17:20.38kerioi mean, how does bridging work?
17:20.48keriodoes it correctly send packets around
17:20.53kerioto the correct destination?
17:22.04keriono hcidump on either side
17:22.05lufIt's ok. bridge sent what it gets to all slave devices.
17:22.21kerio*on neither side
17:22.50lufIt's hard to help you without info.
17:24.35kerioi hope bluez-hcidump from fremantle/tools is good enough for the new bluez
17:24.49kerioanyway, i'm not entirely unconvinced that osx isn't the problem
17:25.16lufkerio: no route available - the machine find no way to send the packet through
17:25.46kerioso i suppose that i'll stop trying in a bit, and try again whenever i get around to installing bluez on my linux partition
17:26.15lufPlease netstat -rn + destination ip ...
17:26.41lufIt seems bluez is ok.
17:27.02lufIt connected and also setup the bnep + bridge.
17:27.33kerioyeah, it's just that /sbin/ifup isn't reentrant so it fails to reconfigure it the second time around
17:27.43keriowell, i suppose that it *is* reentrant
17:27.57lufkerio: let's try tcpdump on osx side.
17:28.34kerioluf: apparently 192.168.99.15 is in osx's routing table
17:28.38kerioand it's correctly assigned
17:29.12keriohttp://pastebin.ca/2316899
17:30.06kerioand, when pinging, i get something in hcidump
17:30.15kerio> ACL data: handle 11 flags 0x02 dlen 91
17:30.15kerio<PROTECTED>
17:30.19lufwhat about iptables?
17:30.20kerioone of those for each ping
17:31.11lufkerio: you ping from osx to N900 and you see something on N900 hcidump?
17:31.14kerioyes
17:31.21lufwhat about tcpdump?
17:31.45lufn900$ tcpdump -i bnep0 -nn
17:32.06kerioluf: iptables on n900 is flush and open, firewall on os x was enabled, is now disabled, changed nothing
17:32.35keriowell this is awkward
17:32.36kerio18:32:25.282390 IP 192.168.99.14 > 192.168.99.15: ICMP echo request, id 40060, seq 5, length 64
17:32.56kerionothing on btnap
17:33.01keriodafuq, bridge
17:33.51lufn900$ ifconfig -a
17:34.45lufn900$ brctl  show btnap
17:35.15kerioeverything seems fine
17:35.16keriohttp://pastebin.ca/2316901
17:38.33lufkerio: did you upgrade kernel?
17:38.55keriolatest kp52
17:39.01kerioPali: did you change anything in the bridging?
17:39.16Palino
17:39.40lufkerio: let's try - brctl delif btnap bnep0; brctl addif btnap bnep0
17:42.59keriostill only receiving pings on bnep0 but not btnap
17:45.34lufkerio: brctl showstp btnap
17:46.26keriobrctl: invalid argument 'showstp' to 'brctl'
17:46.30keriowhat am i looking for?
17:46.43lufkerio: Check whether the bridge ports are in the ‘forwarding’ state
17:46.48keriobrctl show says "STP enabled no"
17:46.53lufhttp://www.microhowto.info/troubleshooting/troubleshooting_ethernet_bridging_on_linux.html
17:51.24lufkerio: what package provides you brctl? (dpkg -S <full path to brctl>) and what version (brctl --version)?
17:52.38keriobusybox-power
17:53.35luflet's try http://merlin1991.at/~luf/bluez/bridge-utils_1.5-4maemo1_armel.deb
18:00.08keriok, one sec
18:02.11lufkerio: shot into the dark - don't you have wifi/usb with same network as the bluetooth one?
18:03.25lufkerio: BTW definitely the problem isn't in bluetooth.
18:03.36kerionope, i don't have 192.168.99.* anywhere
18:03.39kerioexcept bt nap
18:09.49kerioluf: state forwarding
18:10.16lufkerio: ebtables -t filter -L --Lc
18:10.39keriosay what
18:10.52luflet's check the link I posted.
18:11.19kerioebtables: command not found
18:11.26kerionot in bridge-utils, i'm afraid
18:12.27lufbrctl showmacs btnap
18:12.58kerioluf: the bt mac
18:13.04kerio"is local?" yes
18:15.45lufkerio: can you ping from n900 to osx?
18:16.11kerionope, Destination Host Unreachable
18:16.51kerioalso, tcpdump right now showed 19:15:39.664066 ARP, Request who-has 192.168.99.15 tell 192.168.99.14, length 28
18:17.00kerioand "No route to host" on the osx side
18:17.21keriobut now it has somehow figured that out, and i'm seeing the echo requests again
18:17.27keriomeh, fuck this
18:18.10keriofuck bluetooth, fuck networking, and fuck anything that's not an actual piece of copper shoved into something
18:19.28lufkerio: :D let's: brctl delif btnap bnep0; ifconfig bnep0 192.168.99.15 netmask 255.255.255.0 up
18:19.50lufIt seems there is some problem in bridge (no idea what).
18:20.39lufkerio: in the ifconfig you pasted you can see RX packets:138 in bnep0 but RX packets:0 in btnap :(
18:23.46lufkerio: had you tried to reboot the phone?
18:23.50keriojust did
18:31.00*** join/#maemo-ssu WizardNumberNext (~marek@2001:470:1f08:178b:92e6:baff:fe50:bed4)
18:31.11keriostill no change
18:32.46lufbrctl delif btnap bnep0; ifconfig bnep0 192.168.99.15 netmask 255.255.255.0 up ?
18:33.11lufI forget - ifconfig btnap down
18:38.24keriofucking hell, not even directly
18:38.36kerioat this point, i'm ready to blame os x
18:38.55lufcat /proc/sys/net/bridge/*
18:39.11kerioluf: all 1
18:39.33lufkerio: you said that tcpdump shows the packet on bnep0 ...
18:40.12kerioit does
18:40.15lufkerio: set all to 0 (just for test)
18:40.18kerioi see echo request and echo reply now
18:40.26keriobut the replies don't get to the os x side or something
18:40.34lufkerio: ok (without bridge)
18:40.40lufkerio: check also hcidump
18:41.33kerioit's weird, i only see one entry in hcidump for every request/reply
18:42.01keriomeh, fuck this
18:42.04lufbrctl delbr btnap
18:43.14kerionope, spent way too much time on this
18:43.38kerioand can't reboot my laptop at the moment
18:43.46kerioi'll wait until i can do that
18:43.55kerioand then i'll probably try with an actual bluez on that side too
18:44.03lufkerio: As you wish.
18:44.19kerioapparently there's no way to diagnose a bluetooth problem on os x :s
18:44.32lufBut it seems that N900 doesn't send tha packet back to osx.
18:44.40kerioindeed
18:44.59lufMaybe it's confused with btnap ... (just remove it using brctl delbr btnap)
18:46.47lufkerio: once you want to test bridge once again let's try set all /proc/sys/net/bridge/* to zero.
18:50.50lufmerlin1991: ping
18:52.30merlin1991luf: pong
18:54.11lufI had Hash Sum mismatch with extras devel. Are you still investigating it?
18:55.44lufmerlin1991: I went through using fremantle-1.3 instead of just fremantle.
18:58.49merlin1991yeah I'm still investigating
18:59.03merlin1991or rather trying to find the time to write the script for an automated check of *EVERYTHING*
19:00.08lufmerlin1991: Will it check also kerio's bridge? :D
19:00.19lufI'm going offline. Have a nice weekend.
