[18:48] <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.
[18:56] <highvoltage> hi Guus_
[18:56] <highvoltage> Arvind Raj did packaging for it, but it needs some changes to make it into the archive
[18:57] <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
[18:58] <Guus_> ah cool, thanks for the effort
[21:27] <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
[21:28] <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
[21:29] <Damianos> thank you so much and I am so sorry about the last few attempts
[21:32] <Damianos> there is no record of anything said by you, hyberbyte or myself on the ltsp.org logs. The ubuntu.org logs have a "Global day of mobilisation" banner
[21:35] <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
[21:37] <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
[21:39] <Hyperbyte> At least this time he didn't ignore us.
[21:39] <Hyperbyte> Hahahaha
[21:39] <alkisg> Hehe
[21:40] <alkisg> He probably has set a gateway for the wired nic, and they're both on the same subnet
[21:41] <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?
[21:42] <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
[21:43] <Damianos> http://paste.ubuntu.com/655329/
[21:44] <alkisg> Hmmm can you also pastebin what Hyperbyte told you?  ip route show
[21:45] <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
[21:47] <Hyperbyte> This is the point where we can talk again behind his back for a little while. ;->
[21:48] <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
[21:49] <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.
[21:50] <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
[21:51] <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.
[21:52] <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?
[21:53] <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?
[21:54] <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
[21:55] <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
[21:56] <Hyperbyte> Damianos, also, wild guess here, try putting the wlan1 interface below the eth0 interface in the configuration.
[21:57] <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
[21:58] <Damianos> here goes...if you see me leave the room it's a bust
[22:01] <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
[22:02] <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
[22:03] <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
[22:04] <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
[22:06] <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
[22:07] <Hyperbyte> To configure wlan1 as default gateway, add the line
[22:07] <Hyperbyte> up route add default gw 192.168.2.1
[22:08] <Hyperbyte> That might even work when it's still dhcp... I'm just curious if eth0 is gonna override even that
[22:11] <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 ?
[22:12] <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?
[22:13] <Hyperbyte> You say you enable wlan1 and then it goes wrong
[22:13] <Hyperbyte> What do you type/do to enable wlan1?
[22:14] <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
[22:15] <Hyperbyte> Your /etc/network/interfaces
[22:15] <Hyperbyte> Should contain:
[22:15] <Hyperbyte> http://razor.middelkoop.cc/~dj/damianos.txt
[22:15] <Hyperbyte> That
[22:16] <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
[22:20] <Hyperbyte> Any luck?
[22:21] <Damianos> well, internet is now working....thin client is not booting...should I restart dhcp?
[22:22] <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
[22:23] <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?
[22:24] <Damianos> eth0 is not listed
[22:24] <Hyperbyte> Type
[22:24] <Hyperbyte> ifup eth0
[22:24] <Hyperbyte> Haha
[22:24] <Hyperbyte> Wtf...
[22:28] <Damianos> ethernet plugged in  = thin client working internet not working
[22:29] <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
[22:30] <Damianos> it's funny...earlier I tried to pull up NetworkManager via ssh and it said it was already running
[22:32] <Hyperbyte> According to Alkis NetworkManager is gonna solve all your problems
[22:32] <Hyperbyte> Just make sure you get rid of the old config
[22:33] <Hyperbyte> As in, /etc/network/interfaces
[22:33] <Damianos> ok
[22:50] <Damianos> well, I looked in NM-applet and it's not seeing eth0
[22:51] <Damianos> the cable is plugged in but no mention of anything ethernet
[22:53] <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
[23:12] <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
