lufmerlin1991: ping18:36
merlin1991luf: pong18:37
lufmerlin1991: I'm not able to ssh to merlin1991.at :(18:38
merlin1991what does it say?18:38
lufmerlin1991: is the problem on my side? It says nothing ...18:38
merlin1991I get in18:38
lufConnection closed by 188.40.39.1118:38
merlin1991odd18:39
merlin1991let me check hte logs18:39
merlin1991luf: nothing there about even a logon attempt18:40
lufHmmm. Ok.18:41
kerioohai luf18:43
lufkerio: hello :)18:45
lufStrange I'm there now.18:45
lufNothing changed.18:45
lufmerlin1991: ^^^18:46
merlin1991nettwork hiccup maybe?18:46
lufmerlin1991: seems so. I maybe should think about different provider.18:47
kerioluf: i can't get bt pan to work :'(18:52
lufkerio: what changed?18:52
kerioidk18:53
kerionothing18:53
kerio...weeeeeeeell18:53
lufDon't keep the change just for yourself. Let's share ;)18:53
kerioi did delete a bunch of packages, and i moved my /home to ext418:54
kerioand right now, my Conversations show a scrollbar that i have to use to scroll18:54
lufWhat bt debug says about it?18:54
kerioluf: one sec, i'm re-pairing18:55
lufBT PAN shouldn't depend on any packages.18:55
kerioindeed18:55
freemangordonmerlin1991: meeting on Monday?18:55
kerioluf: what do you mean by bt debug?18:55
merlin1991freemangordon: yep18:56
lufkerio: bluetoothd -n -d '*' and syslog output18:56
kerioi see18:57
kerio...how am i supposed to do this? i can't use wifi :s18:57
freemangordonmerlin1991: do others know about it?18:57
lufkerio: terminal on N900 ? edit /etc/event.d/bluetoothd18:58
merlin1991Pali: ping18:58
Palimerlin1991: pong19:00
kerioluf: nothing wrong at all19:01
keriobut i'm still getting no route available/destination unreachable/timeout19:01
merlin1991Pali: got time monday evening?19:01
lufkerio: there has to be something in syslog when you try to connect.19:02
Palimerlin1991, I think yes19:02
merlin1991meeting then19:02
kerioluf: oh of course there is19:02
lufmerlin1991: ok19:02
lufkerio: pastebin?19:02
keriohttp://pastebin.ca/231689019:03
kerioeverything seems perfectly fine19:03
kerioexcept that the packets aren't flowing19:03
merlin1991freemangordon: now everyone knows :)19:03
lufkerio: NAP on N900 and client is you computer, right?19:04
kerioyes19:04
lufifconfig -a ?19:04
kerioah fuck where's my ip19:05
luf:D That seems like the problem :D19:05
kerioi swear that there was the ip at some point19:05
kerioand it still didn't work19:05
luf/etc/network/interfaces?19:05
keriolike... right now19:06
lufifconfig -a ? netstat -rn ?19:07
lufdinner is calling me ...19:07
keriobtnap with its address, bnep0 up, bridge is correct19:08
lufkerio: ifconfig -a ? netstat -rn ?19:18
lufkerio: and what the opposite side? also ok?19:18
lufkerio: tcpdump ? hcidump ? (on both endpoints)19:19
keriorouting table is ok19:20
kerioalthough...19:20
kerioshould the route go for btnap?19:20
kerioi mean, how does bridging work?19:20
keriodoes it correctly send packets around19:20
kerioto the correct destination?19:20
keriono hcidump on either side19:22
lufIt's ok. bridge sent what it gets to all slave devices.19:22
kerio*on neither side19:22
lufIt's hard to help you without info.19:22
kerioi hope bluez-hcidump from fremantle/tools is good enough for the new bluez19:24
kerioanyway, i'm not entirely unconvinced that osx isn't the problem19:24
lufkerio: no route available - the machine find no way to send the packet through19:25
kerioso i suppose that i'll stop trying in a bit, and try again whenever i get around to installing bluez on my linux partition19:25
lufPlease netstat -rn + destination ip ...19:26
lufIt seems bluez is ok.19:26
lufIt connected and also setup the bnep + bridge.19:27
kerioyeah, it's just that /sbin/ifup isn't reentrant so it fails to reconfigure it the second time around19:27
keriowell, i suppose that it *is* reentrant19:27
lufkerio: let's try tcpdump on osx side.19:27
kerioluf: apparently 192.168.99.15 is in osx's routing table19:28
kerioand it's correctly assigned19:28
keriohttp://pastebin.ca/231689919:29
kerioand, when pinging, i get something in hcidump19:30
kerio> ACL data: handle 11 flags 0x02 dlen 9119:30
kerio    L2CAP(d): cid 0x0040 len 87 [psm 0]19:30
lufwhat about iptables?19:30
kerioone of those for each ping19:30
lufkerio: you ping from osx to N900 and you see something on N900 hcidump?19:31
kerioyes19:31
lufwhat about tcpdump?19:31
lufn900$ tcpdump -i bnep0 -nn19:31
kerioluf: iptables on n900 is flush and open, firewall on os x was enabled, is now disabled, changed nothing19:32
keriowell this is awkward19:32
kerio18:32:25.282390 IP 192.168.99.14 > 192.168.99.15: ICMP echo request, id 40060, seq 5, length 6419:32
kerionothing on btnap19:32
keriodafuq, bridge19:33
lufn900$ ifconfig -a19:33
lufn900$ brctl  show btnap19:34
kerioeverything seems fine19:35
keriohttp://pastebin.ca/231690119:35
*** jade has quit IRC19:35
lufkerio: did you upgrade kernel?19:38
keriolatest kp5219:38
kerioPali: did you change anything in the bridging?19:39
Palino19:39
lufkerio: let's try - brctl delif btnap bnep0; brctl addif btnap bnep019:39
keriostill only receiving pings on bnep0 but not btnap19:42
lufkerio: brctl showstp btnap19:45
keriobrctl: invalid argument 'showstp' to 'brctl'19:46
keriowhat am i looking for?19:46
lufkerio: Check whether the bridge ports are in the ‘forwarding’ state19:46
keriobrctl show says "STP enabled no"19:46
lufhttp://www.microhowto.info/troubleshooting/troubleshooting_ethernet_bridging_on_linux.html19:46
lufkerio: what package provides you brctl? (dpkg -S <full path to brctl>) and what version (brctl --version)?19:51

keriok, one sec20:00
lufkerio: shot into the dark - don't you have wifi/usb with same network as the bluetooth one?20:02
lufkerio: BTW definitely the problem isn't in bluetooth.20:03
kerionope, i don't have 192.168.99.* anywhere20:03
kerioexcept bt nap20:03
kerioluf: state forwarding20:09
lufkerio: ebtables -t filter -L --Lc20:10
keriosay what20:10
luflet's check the link I posted.20:10
kerioebtables: command not found20:11
kerionot in bridge-utils, i'm afraid20:11
lufbrctl showmacs btnap20:12
kerioluf: the bt mac20:12
kerio"is local?" yes20:13
lufkerio: can you ping from n900 to osx?20:15
kerionope, Destination Host Unreachable20:16
kerioalso, tcpdump right now showed 19:15:39.664066 ARP, Request who-has 192.168.99.15 tell 192.168.99.14, length 2820:16
kerioand "No route to host" on the osx side20:17
keriobut now it has somehow figured that out, and i'm seeing the echo requests again20:17
keriomeh, fuck this20:17
keriofuck bluetooth, fuck networking, and fuck anything that's not an actual piece of copper shoved into something20:18
lufkerio: :D let's: brctl delif btnap bnep0; ifconfig bnep0 192.168.99.15 netmask 255.255.255.0 up20:19
lufIt seems there is some problem in bridge (no idea what).20:19
lufkerio: in the ifconfig you pasted you can see RX packets:138 in bnep0 but RX packets:0 in btnap :(20:20
lufkerio: had you tried to reboot the phone?20:23
keriojust did20:23
*** arcean__ is now known as arcean20:26
*** WizardNumberNext has joined #maemo-ssu20:30
keriostill no change20:31
lufbrctl delif btnap bnep0; ifconfig bnep0 192.168.99.15 netmask 255.255.255.0 up ?20:32
lufI forget - ifconfig btnap down20:33
keriofucking hell, not even directly20:38
kerioat this point, i'm ready to blame os x20:38
lufcat /proc/sys/net/bridge/*20:38
kerioluf: all 120:39
lufkerio: you said that tcpdump shows the packet on bnep0 ...20:39
kerioit does20:40
lufkerio: set all to 0 (just for test)20:40
kerioi see echo request and echo reply now20:40
keriobut the replies don't get to the os x side or something20:40
lufkerio: ok (without bridge)20:40
lufkerio: check also hcidump20:40
kerioit's weird, i only see one entry in hcidump for every request/reply20:41
keriomeh, fuck this20:42
lufbrctl delbr btnap20:42
kerionope, spent way too much time on this20:43
kerioand can't reboot my laptop at the moment20:43
kerioi'll wait until i can do that20:43
kerioand then i'll probably try with an actual bluez on that side too20:43
lufkerio: As you wish.20:44
kerioapparently there's no way to diagnose a bluetooth problem on os x :s20:44
lufBut it seems that N900 doesn't send tha packet back to osx.20:44
kerioindeed20:44
lufMaybe it's confused with btnap ... (just remove it using brctl delbr btnap)20:44
lufkerio: once you want to test bridge once again let's try set all /proc/sys/net/bridge/* to zero.20:46
lufmerlin1991: ping20:50
merlin1991luf: pong20:52
lufI had Hash Sum mismatch with extras devel. Are you still investigating it?20:54
lufmerlin1991: I went through using fremantle-1.3 instead of just fremantle.20:55
merlin1991yeah I'm still investigating20:58
merlin1991or rather trying to find the time to write the script for an automated check of *EVERYTHING*20:59
lufmerlin1991: Will it check also kerio's bridge? :D21:00
lufI'm going offline. Have a nice weekend.21:00
