| Guus_ | Hello folks, | 18:48 |
|---|---|---|
| Guus_ | i was wondering, is there any chance that OpenTeacher will be included in the next edubuntu? | 18:48 |
| Guus_ | it fits right in. | 18:48 |
| highvoltage | hi Guus_ | 18:56 |
| highvoltage | Arvind Raj did packaging for it, but it needs some changes to make it into the archive | 18:56 |
| highvoltage | the deadline is basically on August 11, I'm going to try to get it in to the archives before then even if it's not in 100% perfect state, and then we could have it included in Edubuntu | 18:57 |
| Guus_ | ah cool, thanks for the effort | 18:58 |

| Damianos | Need some help troubleshooting a network problem. I have an ltsp server with a wireless NIC and an ethernet NIC. The ethernet is faceing the private LAN and boots thin clients fine. Unfortunately, when the ethernet is plugged in I can't get any internet on the server or the clients. Furthermore, with ethernet disconnected, I can connect to my router but not to the internet | 21:27 |
| alkisg | Damianos: yesterday I answered you, today Hyperbyte did | 21:28 |
| alkisg | You just ignore us... :( | 21:28 |
| Damianos | no sir! I had to try and do IRC on my phone and it keeps kicking me out of the room | 21:28 |
| alkisg | Please read the irc logs, and see our answers there | 21:28 |
| Damianos | ok, how do I check the logs? | 21:28 |
| alkisg | irclogs.ubuntu.org, irclogs.ltsp.org | 21:28 |
| Damianos | thank you so much and I am so sorry about the last few attempts | 21:29 |
| Damianos | there is no record of anything said by you, hyberbyte or myself on the ltsp.org logs. The ubuntu.org logs have a "Global day of mobilisation" banner | 21:32 |
| alkisg | ubuntu.com, sorry | 21:35 |
| Damianos | ah, ok | 21:35 |
| alkisg | ubuntu.com is for edubuntu, while I think with hyperbyte you talked (or tried to) in #ltsp so it's in irclogs.ltsp.org | 21:35 |
| alkisg | Damianos: anyway, let's start over | 21:37 |
| Damianos | ok | 21:37 |
| alkisg | First, can you paste the output of `ip addr show` ? | 21:37 |
| alkisg | In pastebin, e.g. paste.ubuntu.com | 21:37 |
| Damianos | ok | 21:37 |
| Hyperbyte | At least this time he didn't ignore us. | 21:39 |
| Hyperbyte | Hahahaha | 21:39 |
| alkisg | Hehe | 21:39 |
| alkisg | He probably has set a gateway for the wired nic, and they're both on the same subnet | 21:40 |
| Hyperbyte | Hence me asking him to pastebin ip route show | 21:41 |
| Hyperbyte | :) | 21:41 |
| Hyperbyte | Ah | 21:41 |
| Damianos | http://paste.ubuntu.com/655327/ | 21:41 |
| Damianos | sorry, whenever the ethernet is connected nothing on my network can connect to the internet | 21:41 |
| alkisg | OK | 21:41 |
| alkisg | How does your wired nic get its IP? | 21:41 |
| alkisg | From network manager, or from /etc/network/interfaces? | 21:41 |
| Damianos | I'm not sure | 21:42 |
| alkisg | cat /etc/network/interfacs | 21:42 |
| alkisg | es | 21:42 |
| alkisg | If you see IPs there, that's the one | 21:42 |
| alkisg | If so, please put that too to pastebin | 21:42 |
| Damianos | http://paste.ubuntu.com/655329/ | 21:43 |
| alkisg | Hmmm can you also pastebin what Hyperbyte told you? ip route show | 21:44 |
| Damianos | one sec...I'll plug the ethernet in so I replicate the problem and then do it | 21:45 |
| Hyperbyte | Wait | 21:45 |
| alkisg | ok | 21:45 |
| Hyperbyte | Do both | 21:45 |
| Damianos | ok | 21:45 |
| Hyperbyte | ip route show in both conditions | 21:45 |
| Hyperbyte | This is the point where we can talk again behind his back for a little while. ;-> | 21:47 |
| alkisg | Haha | 21:48 |
| alkisg | And we've verified he won't see the logs :P | 21:48 |
| Damianos | http://paste.ubuntu.com/655331/ | 21:48 |
| Hyperbyte | Different default gateway | 21:48 |
| Damianos | is that what the first address represents? | 21:49 |
| Hyperbyte | When you enable the local network, Ubuntu sets that as default route | 21:49 |
| Hyperbyte | No | 21:49 |
| Hyperbyte | 'default via IP' | 21:49 |
| Damianos | ok | 21:49 |
| alkisg | It's weird though, because he doesn't have a route in his /etc/network/interfaces. | 21:49 |
| Hyperbyte | What does the 'auto eth0' mean? | 21:50 |
| Hyperbyte | No actually | 21:50 |
| alkisg | "bring that interface up on boot, according to what's written below" | 21:50 |
| Hyperbyte | I think the problem is that he -needs- to define a route | 21:50 |
| Hyperbyte | By default, any interface that comes up last, is default route | 21:51 |
| alkisg | Why? If an interface doesn't have a route, why would it be the default route? | 21:51 |
| Hyperbyte | alkisg, there needs to be a default route. | 21:51 |
| alkisg | Per interface? | 21:51 |
| Hyperbyte | No, one global default route. | 21:51 |
| alkisg | OK, so why would it be wrong to not have one for eth0? | 21:52 |
| Hyperbyte | The dhcp interface should take precedence though I think. | 21:52 |
| Hyperbyte | No, I meant he needs to have one for wlan0 | 21:52 |
| alkisg | I think I've tried that several times, and it worked fine. | 21:52 |
| alkisg | That's given by dhcp | 21:52 |
| alkisg | For wlan1 | 21:52 |
| alkisg | Damianos: which ubuntu version is that? | 21:52 |
| Damianos | 10.0.4 but I originally installed 9.10 and then upgraded | 21:53 |
| Hyperbyte | alkisg, could we be looking at a configuration file that isn't used, because NetworkManager is active anyways? | 21:53 |
| alkisg | When network manager sees an interface declaration in /etc/network/interfaces, it ignores it, and in the UI it says "not managed" | 21:54 |
| Hyperbyte | Okay | 21:54 |
| alkisg | So /me hasn't yet thought of how eth0 gets that route... | 21:55 |
| Hyperbyte | For starters, you could try removing the 'network' and 'broadcast' lines from there. They shouldn't be needed. | 21:55 |
| Hyperbyte | Don't think that'll help much, but at least it's something. | 21:55 |
| alkisg | Right... and maybe if you defined gateway 0.0.0.0, it would solve your problem, but without realizing what caused it | 21:55 |
| Hyperbyte | Damianos, also, wild guess here, try putting the wlan1 interface below the eth0 interface in the configuration. | 21:56 |
| Damianos | ok | 21:57 |
| Damianos | brb | 21:57 |
| * alkisg has started advicing teachers here to use network manager instead of /etc/network/interfaces | 21:57 | |
| alkisg | It usually gives them less trouble | 21:57 |
| Damianos | here goes...if you see me leave the room it's a bust | 21:58 |
| alkisg | Hmm... Damianos, one reason why you might got a gateway with that /etc/network/interfaces, is if you manually tried "dhclient eth0". Did you? | 22:01 |
| Hyperbyte | eth0 != dhcp | 22:01 |
| alkisg | If he manually requested it, why not? | 22:02 |
| Damianos | I don't remember | 22:02 |
| Damianos | I don't think so...I messed with a previous installation on this machine but then did a clean install | 22:02 |
| Hyperbyte | What's even weirder | 22:02 |
| Hyperbyte | Is that it leaves the dhcp fail range (169.254.0.0/16) to wlan1 but sets default to eth0 | 22:02 |
| Damianos | what is the significance of the "auto" before the interface name? | 22:03 |
| Hyperbyte | 23:50 <alkisg> "bring that interface up on boot, according to what's written | 22:03 |
| Hyperbyte | below" | 22:03 |
| alkisg | (12:50:24 πμ) Hyperbyte: What does the 'auto eth0' mean? | 22:03 |
| alkisg | (12:50:49 πμ) alkisg: "bring that interface up on boot, according to what's written below" | 22:03 |
| Hyperbyte | Hehe | 22:03 |
| alkisg | Haha | 22:03 |
| Hyperbyte | Did you remove the 'network' and 'broadcast' lines? | 22:03 |
| Damianos | I'll do that right now | 22:03 |
| alkisg | Anyway /me needs to go, battery low and no wifi on room | 22:04 |
| Hyperbyte | Enjoy your vacation! | 22:04 |
| Damianos | thanks again alkisg | 22:04 |
| alkisg | Carry on, and good luck :) | 22:04 |
| Damianos | I commented out the network and broadcast lines from the eth0 | 22:04 |
| Damianos | here goes | 22:04 |
| Damianos | what if I gave myself a static IP on wlan1? | 22:06 |
| Damianos | would that force it to look at the correct gateway? | 22:06 |
| Hyperbyte | Probably helps. | 22:06 |
| Hyperbyte | Well no, but then we can configure a static gateway | 22:06 |
| Hyperbyte | To configure wlan1 as default gateway, add the line | 22:07 |
| Hyperbyte | up route add default gw 192.168.2.1 | 22:07 |
| Hyperbyte | That might even work when it's still dhcp... I'm just curious if eth0 is gonna override even that | 22:08 |
| Hyperbyte | Actually, I think you could even just specify 'gateway 192.168.2.1' under wlan1 | 22:11 |
| Hyperbyte | Sorry, I'm a bit unfamiliar with Ubuntu network config | 22:11 |
| Damianos | should I just type it in etc/network/interfaces ? | 22:11 |
| Hyperbyte | How are you exactly bringing up/down eth2? | 22:12 |
| Hyperbyte | Erm, wlan1? | 22:12 |
| Damianos | what do you mean by bringing up/down? | 22:12 |
| Hyperbyte | You say you enable wlan1 and then it goes wrong | 22:13 |
| Hyperbyte | What do you type/do to enable wlan1? | 22:13 |
| Damianos | oh...when I plug in my ethernet cable | 22:14 |
| Hyperbyte | Okay | 22:14 |
| Hyperbyte | We're gonna do this the proper way from now on | 22:14 |
| Hyperbyte | You don't disconnect your ethernet cable | 22:14 |
| Hyperbyte | You use 'ifdown eth0' 'ifup eth0' | 22:14 |
| Hyperbyte | Also | 22:14 |
| Hyperbyte | Your /etc/network/interfaces | 22:15 |
| Hyperbyte | Should contain: | 22:15 |
| Hyperbyte | http://razor.middelkoop.cc/~dj/damianos.txt | 22:15 |
| Hyperbyte | That | 22:15 |
| Hyperbyte | And after that's done, you plug it all cables, make everything the way it's supposed to be | 22:16 |
| Hyperbyte | And then run | 22:16 |
| Hyperbyte | sudo /etc/init.d/networking restart | 22:16 |
| Damianos | ok | 22:16 |
| Hyperbyte | Any luck? | 22:20 |
| Damianos | well, internet is now working....thin client is not booting...should I restart dhcp? | 22:21 |
| Hyperbyte | Your network works like this, with everything connected/plugged in? | 22:22 |
| Damianos | hold on...there was a warning | 22:22 |
| Damianos | "WARNING: ifup -a is disabled in favour of NetworkManager. | 22:22 |
| Damianos | Set ifupdown:managed=false in /etc/NetworkManager/nm-system-settings.conf. | 22:22 |
| Damianos | ...done. | 22:22 |
| Damianos | " | 22:22 |
| Hyperbyte | That's probably due to me not understanding Ubuntu network enough | 22:22 |
| Hyperbyte | If it still works after a reboot I wouldn't worry about it. :) | 22:23 |
| Damianos | I'm going to try and restart dhcp | 22:23 |
| Hyperbyte | If you type 'ifconfig', do you see both interfaces there, with the correct IP's? | 22:23 |
| Damianos | eth0 is not listed | 22:24 |
| Hyperbyte | Type | 22:24 |
| Hyperbyte | ifup eth0 | 22:24 |
| Hyperbyte | Haha | 22:24 |
| Hyperbyte | Wtf... | 22:24 |
| Damianos | ethernet plugged in = thin client working internet not working | 22:28 |
| Hyperbyte | Okay | 22:29 |
| Hyperbyte | Get rid of /etc/network/interfaces | 22:29 |
| Hyperbyte | And do it like this: https://help.ubuntu.com/community/NetworkManager0.7 | 22:29 |
| Damianos | it's funny...earlier I tried to pull up NetworkManager via ssh and it said it was already running | 22:30 |
| Hyperbyte | According to Alkis NetworkManager is gonna solve all your problems | 22:32 |
| Hyperbyte | Just make sure you get rid of the old config | 22:32 |
| Hyperbyte | As in, /etc/network/interfaces | 22:33 |
| Damianos | ok | 22:33 |
| Damianos | well, I looked in NM-applet and it's not seeing eth0 | 22:50 |
| Damianos | the cable is plugged in but no mention of anything ethernet | 22:51 |
| Damianos | actually correction: in Network Connections there is mention of ifupdown (eth0) but I don't know if that is what I should be setting up | 22:53 |
| Damianos | ok...after rebooting auto eth0 now shows up in NM | 23:12 |
| Damianos | I have to go pick up my wife from school so I'll be back in 45...thanks again for taking the time | 23:12 |
| Damianos | you guys are awesome | 23:12 |
