[18:48] Hello folks, [18:48] i was wondering, is there any chance that OpenTeacher will be included in the next edubuntu? [18:48] it fits right in. [18:56] hi Guus_ [18:56] Arvind Raj did packaging for it, but it needs some changes to make it into the archive [18:57] 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 [18:58] ah cool, thanks for the effort === EyesIsMine is now known as Eyes|Sleeping [21:27] 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 [21:28] Damianos: yesterday I answered you, today Hyperbyte did [21:28] You just ignore us... :( [21:28] no sir! I had to try and do IRC on my phone and it keeps kicking me out of the room [21:28] Please read the irc logs, and see our answers there [21:28] ok, how do I check the logs? [21:28] irclogs.ubuntu.org, irclogs.ltsp.org [21:29] thank you so much and I am so sorry about the last few attempts [21:32] 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 [21:35] ubuntu.com, sorry [21:35] ah, ok [21:35] ubuntu.com is for edubuntu, while I think with hyperbyte you talked (or tried to) in #ltsp so it's in irclogs.ltsp.org [21:37] Damianos: anyway, let's start over [21:37] ok [21:37] First, can you paste the output of `ip addr show` ? [21:37] In pastebin, e.g. paste.ubuntu.com [21:37] ok [21:39] At least this time he didn't ignore us. [21:39] Hahahaha [21:39] Hehe [21:40] He probably has set a gateway for the wired nic, and they're both on the same subnet [21:41] Hence me asking him to pastebin ip route show [21:41] :) [21:41] Ah [21:41] http://paste.ubuntu.com/655327/ [21:41] sorry, whenever the ethernet is connected nothing on my network can connect to the internet [21:41] OK [21:41] How does your wired nic get its IP? [21:41] From network manager, or from /etc/network/interfaces? [21:42] I'm not sure [21:42] cat /etc/network/interfacs [21:42] es [21:42] If you see IPs there, that's the one [21:42] If so, please put that too to pastebin [21:43] http://paste.ubuntu.com/655329/ [21:44] Hmmm can you also pastebin what Hyperbyte told you? ip route show [21:45] one sec...I'll plug the ethernet in so I replicate the problem and then do it [21:45] Wait [21:45] ok [21:45] Do both [21:45] ok [21:45] ip route show in both conditions [21:47] This is the point where we can talk again behind his back for a little while. ;-> [21:48] Haha [21:48] And we've verified he won't see the logs :P [21:48] http://paste.ubuntu.com/655331/ [21:48] Different default gateway [21:49] is that what the first address represents? [21:49] When you enable the local network, Ubuntu sets that as default route [21:49] No [21:49] 'default via IP' [21:49] ok [21:49] It's weird though, because he doesn't have a route in his /etc/network/interfaces. [21:50] What does the 'auto eth0' mean? [21:50] No actually [21:50] "bring that interface up on boot, according to what's written below" [21:50] I think the problem is that he -needs- to define a route [21:51] By default, any interface that comes up last, is default route [21:51] Why? If an interface doesn't have a route, why would it be the default route? [21:51] alkisg, there needs to be a default route. [21:51] Per interface? [21:51] No, one global default route. [21:52] OK, so why would it be wrong to not have one for eth0? [21:52] The dhcp interface should take precedence though I think. [21:52] No, I meant he needs to have one for wlan0 [21:52] I think I've tried that several times, and it worked fine. [21:52] That's given by dhcp [21:52] For wlan1 [21:52] Damianos: which ubuntu version is that? [21:53] 10.0.4 but I originally installed 9.10 and then upgraded [21:53] alkisg, could we be looking at a configuration file that isn't used, because NetworkManager is active anyways? [21:54] When network manager sees an interface declaration in /etc/network/interfaces, it ignores it, and in the UI it says "not managed" [21:54] Okay [21:55] So /me hasn't yet thought of how eth0 gets that route... [21:55] For starters, you could try removing the 'network' and 'broadcast' lines from there. They shouldn't be needed. [21:55] Don't think that'll help much, but at least it's something. [21:55] Right... and maybe if you defined gateway 0.0.0.0, it would solve your problem, but without realizing what caused it [21:56] Damianos, also, wild guess here, try putting the wlan1 interface below the eth0 interface in the configuration. [21:57] ok [21:57] brb [21:57] * alkisg has started advicing teachers here to use network manager instead of /etc/network/interfaces [21:57] It usually gives them less trouble [21:58] here goes...if you see me leave the room it's a bust [22:01] 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] eth0 != dhcp [22:02] If he manually requested it, why not? [22:02] I don't remember [22:02] I don't think so...I messed with a previous installation on this machine but then did a clean install [22:02] What's even weirder [22:02] Is that it leaves the dhcp fail range (169.254.0.0/16) to wlan1 but sets default to eth0 [22:03] what is the significance of the "auto" before the interface name? [22:03] 23:50 "bring that interface up on boot, according to what's written [22:03] below" [22:03] (12:50:24 πμ) Hyperbyte: What does the 'auto eth0' mean? [22:03] (12:50:49 πμ) alkisg: "bring that interface up on boot, according to what's written below" [22:03] Hehe [22:03] Haha [22:03] Did you remove the 'network' and 'broadcast' lines? [22:03] I'll do that right now [22:04] Anyway /me needs to go, battery low and no wifi on room [22:04] Enjoy your vacation! [22:04] thanks again alkisg [22:04] Carry on, and good luck :) [22:04] I commented out the network and broadcast lines from the eth0 [22:04] here goes [22:06] what if I gave myself a static IP on wlan1? [22:06] would that force it to look at the correct gateway? [22:06] Probably helps. [22:06] Well no, but then we can configure a static gateway [22:07] To configure wlan1 as default gateway, add the line [22:07] up route add default gw 192.168.2.1 [22:08] That might even work when it's still dhcp... I'm just curious if eth0 is gonna override even that [22:11] Actually, I think you could even just specify 'gateway 192.168.2.1' under wlan1 [22:11] Sorry, I'm a bit unfamiliar with Ubuntu network config [22:11] should I just type it in etc/network/interfaces ? [22:12] How are you exactly bringing up/down eth2? [22:12] Erm, wlan1? [22:12] what do you mean by bringing up/down? [22:13] You say you enable wlan1 and then it goes wrong [22:13] What do you type/do to enable wlan1? [22:14] oh...when I plug in my ethernet cable [22:14] Okay [22:14] We're gonna do this the proper way from now on [22:14] You don't disconnect your ethernet cable [22:14] You use 'ifdown eth0' 'ifup eth0' [22:14] Also [22:15] Your /etc/network/interfaces [22:15] Should contain: [22:15] http://razor.middelkoop.cc/~dj/damianos.txt [22:15] That [22:16] And after that's done, you plug it all cables, make everything the way it's supposed to be [22:16] And then run [22:16] sudo /etc/init.d/networking restart [22:16] ok [22:20] Any luck? [22:21] well, internet is now working....thin client is not booting...should I restart dhcp? [22:22] Your network works like this, with everything connected/plugged in? [22:22] hold on...there was a warning [22:22] "WARNING: ifup -a is disabled in favour of NetworkManager. [22:22] Set ifupdown:managed=false in /etc/NetworkManager/nm-system-settings.conf. [22:22] ...done. [22:22] " [22:22] That's probably due to me not understanding Ubuntu network enough [22:23] If it still works after a reboot I wouldn't worry about it. :) [22:23] I'm going to try and restart dhcp [22:23] If you type 'ifconfig', do you see both interfaces there, with the correct IP's? [22:24] eth0 is not listed [22:24] Type [22:24] ifup eth0 [22:24] Haha [22:24] Wtf... [22:28] ethernet plugged in = thin client working internet not working [22:29] Okay [22:29] Get rid of /etc/network/interfaces [22:29] And do it like this: https://help.ubuntu.com/community/NetworkManager0.7 [22:30] it's funny...earlier I tried to pull up NetworkManager via ssh and it said it was already running [22:32] According to Alkis NetworkManager is gonna solve all your problems [22:32] Just make sure you get rid of the old config [22:33] As in, /etc/network/interfaces [22:33] ok [22:50] well, I looked in NM-applet and it's not seeing eth0 [22:51] the cable is plugged in but no mention of anything ethernet [22:53] 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 [23:12] ok...after rebooting auto eth0 now shows up in NM [23:12] 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] you guys are awesome
