| Shapeshifter | Hi. I'm trying to use tethering via USB with my N900 (providing the laptop with a 3G internet connection). I don't have NetworkManager. I connected the N900 via USB and set it to PC Suite Mode. Two network devices show up in ip link: usbpn0 and enp0s20u1i8. I tried using dhcpcd on both but it's not working, I get a time out. | 11:31 |

It stays in "UNKNOWN" mode. usbpn0: <POINTOPOINT,NOARP,UP,LOWER_UP> mtu 65541 qdisc fq_codel state UNKNOWN mode DEFAULT group default qlen 3. The other device, enp0s20u1i8 stays in DOWN mode, i.e. ip link set enp0s20u1i8 up has no effect | 11:33 |

| Maxdamantus | Shapeshifter: you'd need to either bridge the devices or forward them (either through routing or netfilter rules) and probably do NAT somewhere. | 11:35 |
| Maxdamantus | er, to be clear, the NAT is probably required in both cases. | 11:36 |
| Maxdamantus | I just do: iptables --table nat --append POSTROUTING --out-interface gprs0 -j MASQUERADE && iptables --append FORWARD --in-interface usb0 -j ACCEPT | 11:36 |

| Maxdamantus | Hm. If you've run dhcpcd, it might be hanging around and setting the interface down. | 12:05 |

| Maxdamantus | 192.168.0.202/32 is already part of the 192.168.0.0/24 subnet, which Linux normally adds a route for by default when you configure the interface using that `ifconfig` command. | 12:13 |

| Shapeshifter | It's not helping though. I can set a static ip but the interface remains down http://lpaste.net/5433001060979441664 | 12:18 |
| Shapeshifter | If I plug it in, the very first time I run ip link set usb0 up I get the messages "Gained carrier", "kevent 12 may have been dropped", "Lost carrier". I think it may be a driver bug or something | 12:19 |
| DocScrutinizer05 | this script is like 7 years old and eventually got adapted to new interface naming once (usb0 -> eth4). Otherwise it always worked, given the network doesn't collide with your regular PC ethernet | 12:19 |
| DocScrutinizer05 | ooh, and I usually had to stop the damn network manager on PC | 12:21 |
| DocScrutinizer05 | network manager tries to act smart and thus actually acts terribly stupid | 12:22 |
| Shapeshifter | I'm not using NM. I tried it manually and with systemd-networkd and udev rules. Anyway, I don't think it's a config issue at this point. The interface just can't go up. | 12:23 |
| DocScrutinizer05 | ohmy, systemd | 12:23 |
| Maxdamantus | You're using systemd, which does network management. | 12:23 |
| Maxdamantus | on my Debian machine at work I have this: https://gist.github.com/Maxdamantus/57c2765f2782c0932986 | 12:24 |
| Shapeshifter | Maxdamantus: yeah but I tried it with systemd-networkd disabled as well. | 12:24 |
| DocScrutinizer05 | systemd is worse than NM | 12:24 |
| Maxdamantus | in /etc/network/interfaces.d/n900usb | 12:24 |
| Maxdamantus | I suspect that's a general systemd configuration. | 12:25 |
| Shapeshifter | Maxdamantus: I don't think so. systemd-networkd config is in /etc/systemd/network and uses a different format. | 12:26 |
| Maxdamantus | Ah, so it does. | 12:26 |
| DocScrutinizer05 | isn't it nice how the never actually seen problems that systemd "solves" are creating new problems all over the place, in stuff that worked before? Dang, what does that remind me to... AAH PolypAudio, and AVAHI | 12:28 |
| Shapeshifter | I'm no fan of systemd either but it's here to stay | 12:28 |

See ~nosystemd" | 12:32 |
| DocScrutinizer05 | also note that maemo uses another incompatible concept of cgroups and thus it will be virtually impossible to migrate maemo to systemd | 12:49 |
| Maxdamantus | I imagine maemo's uses of cgroups could probably be merged into systemd's uses of cgroups. | 12:50 |
| Wizzup | DocScrutinizer05: I hope there are no plans to. | 12:50 |
| DocScrutinizer05 | not even get me started about "usr/?bin must live on rootfs" | 12:50 |
| Wizzup | Openrc is just fine. | 12:50 |
| Maxdamantus | in any case, I wouldn't consider them particularly part of maemo. | 12:51 |
| Maxdamantus | not any moreso than Linux 2.6.28 is part of Maemo. | 12:51 |
| Maxdamantus | it's just a random implementation detail in how the maemo software is run. | 12:51 |
| Wizzup | 'random' | 12:52 |
| Maxdamantus | non-maemo-specific. | 12:52 |
| DocScrutinizer05 | Wizzup: 'random'? | 12:53 |
| Wizzup | you're not seeing what Maxdamantus is saying | 12:53 |
| DocScrutinizer05 | ooh, nevermind | 12:53 |
| Wizzup | yep. | 12:53 |
| DocScrutinizer05 | I guess he disagrees with me as usual | 12:54 |
| Maxdamantus | If you ran hildon-desktop, hildon-status-menu, maemo-xinput-sounds, browserd, etc outside of any cgroups, I'd still call it maemo. | 12:54 |
| Maxdamantus | just as if you ran all those things on a kernel other than 2.6.28 | 12:54 |
| Maxdamantus | Its use of cgroups is only an implementation detail in how it's currently run. | 12:55 |
| Maxdamantus | I don't necessarily usually disagree with you, but I'm more likely to voice my opinions about disagreements than agreements. | 12:56 |
| DocScrutinizer05 | Wizzup: ((openrc)) well, iirc OOM (with PA etc) use cgroups in maemo, so you have a szable implementation of phonecalls etc. You don't want to port all that stuff to openrc | 12:57 |
| Maxdamantus | I don't like systemd either, but there isn't much to add by saying that I also dislike it. | 12:57 |
| Wizzup | DocScrutinizer05: openrc supports linux cgroups, and I don't think it will be too hard to port it over | 12:57 |
| DocScrutinizer05 | hmm, it's quite obscure, and iirc parts of OOM are even closed | 12:58 |
| Maxdamantus | parts of OOM? | 12:58 |
| Wizzup | Time to compile v4.5-rc5-n900 | 12:59 |
| Maxdamantus | I'm sure it's a standard feature of cgroups to make processes in certain cgroups killed first by the OOM killer. | 12:59 |
| Maxdamantus | You don't even need cgroups to do it in a way that would be suitable. | 12:59 |

| DocScrutinizer05 | Wizzup: I din't really like upstart but it's waaaaay better than systemd, and I don't see why we should migrate maemo to any other init system | 13:00 |
| Wizzup | because upstart is dead | 13:00 |
| Wizzup | openrc is a very sensible alt. | 13:00 |
| DocScrutinizer05 | it works just fine on all my N900 | 13:00 |
| Wizzup | I don't want to get into this discussion more fyi | 13:00 |
| Wizzup | sure, but many things works well on n900, but they are very outdated | 13:00 |
| Maxdamantus | Chromium has been setting something on its child processes that makes them usually the first to be killed. | 13:00 |
| Wizzup | and to keep a system up to date and healthy, you cannot maintain all components yourself | 13:01 |
| Wizzup | so you have to find upstream that does work for you | 13:01 |
| Maxdamantus | (without cgroups, afaik) | 13:01 |
| *** disco_stu_droid has joined #maemo | 13:01 | |

| Maxdamantus | echo 300 >/proc/$$/oom_score | 13:02 |
| Wizzup | you're not getting my point, I think | 13:02 |
| Wizzup | I am simply saying: you cannot, ever, find enough manpower do to that | 13:02 |
| DocScrutinizer05 | you even less can find the manpower to migrate | 13:02 |
| Wizzup | perhaps | 13:03 |
| DocScrutinizer05 | since upstart is designed reasonably decent (unlike systemd), the effort to keep it alive is marginal, there hardly will show up any new flaws or bugs | 13:05 |
| Wizzup | ... okay. | 13:05 |
| DocScrutinizer05 | the true flaw is apps depending on the init system, I.E. systemd | 13:06 |
| DocScrutinizer05 | no app really depends on upstart | 13:06 |
| DocScrutinizer05 | except for an occasional "systemcl start lircd" or sth like that | 13:07 |
| DocScrutinizer05 | rather "sudo start lircd" | 13:07 |
| bencoh | no, the *true* flow is no fact that with no real upstream we'll keep drifting with old ABIs | 13:09 |
| bencoh | flaw* | 13:09 |
| bencoh | s/no/the/ bleh | 13:09 |
| DocScrutinizer05 | well, if you wanna change the ABI, you need a new major release anyway, since all your programs need recompiling | 13:10 |
| DocScrutinizer05 | that's maemo7 then ;-) | 13:11 |
| bencoh | DocScrutinizer05: recompiling wouldn't be the main issue (it is for closed-source stuff) | 13:12 |
| bencoh | APIs change too | 13:12 |
| Maxdamantus | usually the ABI compatibility is broken by an API incompatibility. | 13:13 |
| DocScrutinizer05 | sure, you can migrate / clone all infra incl extras repio to a maemo7 and recompile everything and hope that nothing breaks from the ABI change | 13:13 |
| Wizzup | or rip out closed parts | 13:13 |
| Maxdamantus | except maybe libpng. I'm not sure what the problem is with that. | 13:13 |
| DocScrutinizer05 | that won't help, you still need to hope that nothing breaks | 13:14 |
| DocScrutinizer05 | I think we're quite far already with ripping out the closed bits | 13:15 |
| DocScrutinizer05 | the whole linux telephony stack is the major issue afaik | 13:15 |
| DocScrutinizer05 | our RE guys boggle from that | 13:16 |
| Wizzup | I know | 13:17 |
| Wizzup | I have yet to live up to my promise to help out there. | 13:17 |
| DocScrutinizer05 | well, luckily most of it is obsolete anyway on Neo900 | 13:18 |
| DocScrutinizer05 | it's just the damn API that's not really documented | 13:18 |
| DocScrutinizer05 | so operating telephony is no problem on Neo900, integrating it with the rest of the system might be | 13:20 |
| DocScrutinizer05 | I could write a bare bones dialer-ui in just 2 days or less. However that won't integrate nicely with phonebook, messaging, status bar, flight mode settings, 911-calls even from lockscreen, etc pp | 13:22 |

| DocScrutinizer05 | that's prolly not a ttyACM or USB interface though | 13:56 |
| Maxdamantus | after doing: ip addr add 192.168.30.1/24 dev usb0; ip link set dev usb0 up | 13:56 |

| Maxdamantus | since it was already configured on the N900 side. | 13:57 |

| DocScrutinizer05 | crw-rw---- 1 root dialout 166, 0 Mar 9 12:39 /dev/ttyACM0 | 13:57 |
| DocScrutinizer05 | ttyACM however is not what we need | 13:57 |
| Shapeshifter | Maxdamantus: so the usb0 is definitely UP? | 14:01 |
| Shapeshifter | Maxdamantus: What do I need to configure on the N900 side? | 14:01 |
| *** clopez has quit IRC | 14:04 | |
| DocScrutinizer05 | Shapeshifter: you seen http://wiki.maemo.org/N900_USB_networking ? | 14:05 |
| Shapeshifter | DocScrutinizer05: yes but in the first sentence it says " to share your PC's internet to N900 via USB" | 14:07 |
| Shapeshifter | I need the other way around | 14:07 |
| Shapeshifter | http://wiki.maemo.org/N900_USB_router I'm trying this now | 14:07 |
| *** clopez has joined #maemo | 14:07 | |
| DocScrutinizer05 | you want the N900 internet access to get shared to PC? | 14:07 |
| parazyd | what is tethering? | 14:08 |
| Shapeshifter | DocScrutinizer05: yes. | 14:08 |
| DocScrutinizer05 | parazyd: that :-) | 14:08 |
| Shapeshifter | Is this jeopardy? | 14:08 |
| DocScrutinizer05 | Shapeshifter: ideally you use NM or something similar to configure N900 as MODEM | 14:08 |
| * Wizzup just does /etc/init.d/net.usb0 start | 14:10 | |
| DocScrutinizer05 | http://wiki.maemo.org/USB_networking | 14:10 |
| Shapeshifter | oh. | 14:11 |
| Shapeshifter | So we've been talking about the other thing for the past hour | 14:11 |
| Shapeshifter | xD | 14:11 |
| DocScrutinizer05 | http://wiki.maemo.org/Debian-Tethering | 14:13 |
| DocScrutinizer05 | well, that's for DUN (BT) | 14:14 |
| Shapeshifter | Is kernel-power still OK with latest CSSU etc? | 14:15 |
| DocScrutinizer05 | yep, afaik | 14:15 |
| DocScrutinizer05 | for (usb)tethering you don't need KP though | 14:16 |
| Shapeshifter | DocScrutinizer05: the article says that if I use the n900 as a "modem", it won't have internet access itself anymore | 14:16 |
| DocScrutinizer05 | tethering actually works in PC-mode | 14:16 |
| DocScrutinizer05 | yes, that's true | 14:16 |
| DocScrutinizer05 | tehtering completely exports the modem, like mass-storage exposts whole storage partitions | 14:17 |
| Shapeshifter | http://wiki.maemo.org/N900_USB_router this looks simple enough, so I'm trying it | 14:17 |
| DocScrutinizer05 | sure, sounds ok | 14:17 |
| DocScrutinizer05 | see last section on http://wiki.maemo.org/N900_USB_router - it clearly lists the differences between tethering and networking | 14:21 |
| Shapeshifter | https://wiki.maemo.org/N900_USB_networking this one says that the N900 provides a default network interface for usb0 | 14:24 |
| Shapeshifter | But I don't have such an interface on the N900. | 14:24 |
| Shapeshifter | I see the config in /etc/network/interfaces but I only have gprs0, lo, phonet0 in ifconfig on the N900. | 14:25 |
| Shapeshifter | and ifub usb0 gives me No such device sure enough | 14:26 |

| Shapeshifter | DocScrutinizer05: not really. I can get a working connection between the laptop and N900 via USB if I configure a static address on the laptop, but so far I can't get an internet connection on the laptop via the N900 | 15:43 |
| Shapeshifter | According to http://wiki.maemo.org/N900_USB_router dhcp should work as well but it doesn't | 15:43 |
| DocScrutinizer05 | hmm, you don't need a dhcp | 15:44 |
| Shapeshifter | DocScrutinizer05: I don't need one, true. Static ip works, dhcp would be convenient I guess. But I haven't figured out yet hot to get internet access on the laptop. | 15:44 |
| DocScrutinizer05 | when you already have a working connection and ip-tables forwarding on N900, you just need a route on your PC | 15:45 |
| Shapeshifter | DocScrutinizer05: like the one in your paste? i.e. /sbin/route add -host 192.168.0.202/32 dev $DEV$ | 15:45 |
| Shapeshifter | What IP do I need to put there? | 15:45 |
| DocScrutinizer05 | similar, yes, however for default route | 15:46 |
| DocScrutinizer05 | default 192.168.4.1 0.0.0.0 UG 0 0 0 eth0 | 15:46 |
| DocScrutinizer05 | 192.168.4.0 * 255.255.255.0 U 1 0 0 eth0 | 15:47 |
| bencoh | Shapeshifter: http://pastebin.notk.org/pastebin.php?show=d39d5e3db | 15:47 |
| bencoh | here is what I use on my n900 | 15:47 |
| DocScrutinizer05 | I assumed he already has that | 15:48 |
| bencoh | oh and, do use mtr on your laptop to try and debug that kind of routing issues:) | 15:48 |
| DocScrutinizer05 | first his laptop needs to know that Neo900 is the default gateway | 15:48 |
| bencoh | n900* unless I missed something ;) | 15:49 |
| DocScrutinizer05 | or he does >> ping 8.8.8.8 $ip-of-N900 | 15:49 |
| DocScrutinizer05 | oops yep | 15:49 |
| bencoh | dont try to ping n900 | 15:49 |
| bencoh | once you connect to cellular data it disables icmp answers | 15:49 |
| DocScrutinizer05 | no, $ip-of-N900 is the gateway to use, here | 15:49 |
| DocScrutinizer05 | might as well be the NIC name | 15:50 |
| bencoh | icmp echo reply* | 15:50 |
| DocScrutinizer05 | bencoh: huh? | 15:50 |
| DocScrutinizer05 | only with tethering, no? | 15:50 |
| Shapeshifter | It works | 15:51 |
| Shapeshifter | thanks guys | 15:51 |
| DocScrutinizer05 | :-) | 15:51 |
| Shapeshifter | ip r add to default via 192.168.2.15 | 15:51 |
| DocScrutinizer05 | :-)) | 15:51 |
| bencoh | DocScrutinizer05: no | 15:52 |
| DocScrutinizer05 | Shapeshifter: could you check >> ping 192.168.2.15 << now? | 15:52 |
| bencoh | /etc/network/if-post-down.d/zz_enable_icmp_echo_reply:19:echo 0 > /proc/sys/net/ipv4/icmp_echo_ignore_all | 15:52 |
| bencoh | /etc/network/if-up.d/00_disable_icmp_echo_reply:25:echo 1 > /proc/sys/net/ipv4/icmp_echo_ignore_all | 15:52 |
| Shapeshifter | DocScrutinizer05: ping doesn't work | 15:52 |
| DocScrutinizer05 | duh! | 15:52 |
| bencoh | haha :) | 15:53 |
| bencoh | I think they didnt want to do it through netfilter at first, but that lead them to do it system-wide because linux doesn't provide a way to do it per-interface without netfilter iirc | 15:54 |
| DocScrutinizer05 | ack | 15:54 |

| DocScrutinizer05 | ((<bencoh> once you connect to cellular data it disables icmp answers)) alas this helps only marginally, since even with ICMP answers disabled, the GPRS afaik still ACKs the ICMP ping inbound data paket | 20:02 |
| DocScrutinizer05 | IOW GPRS enables TX even when data is strictly inbound-only | 20:02 |
| *** krnlyng has joined #maemo | 20:03 | |
| DocScrutinizer05 | which sucks big time since you can't stop a battery drain from 'rogue' inbound pakets, no matter what you do. Unless you disable GPRS completely | 20:04 |
