LaserJockit should be I think02:46
cottimaalso, the config for pxe clients says it is based on ip.  could it be done by mac address?02:46

aquilesHello dear community05:55
aquilesI wonder if you any of you can answer one question that I've been trying to figuer out for almost 2 hours05:56
aquilesI just installed Edubuntu for my twin girls here at home and when running the update I'm getting the following error:05:57
aquiles"xfonts-75dpi is missing final newline. Does any knows what this means?05:57
LaserJockhmm, weird06:04
LaserJockwhat version of Edubuntu?06:04
aquileshi sorry06:10
aquilesthe version is 7.0406:10
LaserJockand how are you updating?06:10
aquilesI did it by using the update software that prompts you on the right hand side corner of the screen (Sorry I do not the name of it)06:11
aquilesalso I have try the the command line of "sudo apt-get upgrade" and it keeps showing the same error message06:12
LaserJockaquiles: ok, can you paste the command line error message to a pastebin06:23

jonfhancockIs there anyone who can give me a hand with dhcp?08:45
moquistjonfhancock: you can have 192.168.3.17, netmask 255.255.255.0, gateway 192.168.3.25408:49
=== moquist couldn't resist
moquistjonfhancock: :)08:49
moquistjonfhancock: what's the question?08:49
jonfhancockWhy thanks!08:51
jonfhancockI'm trying to set up an edubuntu server.08:51
moquista worthy goal, indeed.08:51
jonfhancockdhcp refuses to start08:51
moquistk08:51
jonfhancockLet me get the syslog.08:51
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd: No subnet declaration for eth0 (0.0.0.0).08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd: ** Ignoring requests on eth0.  If this is not what08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd:    you want, please write a subnet declaration08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd:    in your dhcpd.conf file for the network segment08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd:    to which interface eth0 is attached. **08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd:08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd:08:52
jonfhancockJul  3 11:35:32 ebay-server-linux dhcpd: Not configured to listen on any interfaces!08:52
moquistjonfhancock: do you have a network adapter with an IP address inside the network for which you will provide DHCP?08:52
moquistjonfhancock: that tells us -- nope, you don't.08:52
jonfhancockI guess not08:52
moquistjonfhancock: if you're handing out DHCP for a range within 192.168.0.x, set your server IP address to something in that range -- such as 192.168.0.254.08:52
moquistIf you need to keep the IP address you have (all our IP addresses are 10.x.x.x), edit /etc/ltsp/dhcpd.conf to hand out IP addresses in the range you have, instead of 192.168.x.x.08:53
jonfhancockI'm sorry, I'm a little confused.  The ip on ath (to the web) doesn't matter right.  It's only on eth0 (to the lan) that I'm concerned with?08:54
moquistyes08:56
jonfhancockOk.  So, say I want to use a range like 192.168.160.x08:57
jonfhancockI would set eth0 as static at 192.168.160.25408:57
moquisteither that or 192.168.160.1 is recommended08:58
jonfhancockwith a subnet of 255.255.255.008:58
jonfhancockk08:58
moquistsounds good so far08:58
moquistthen your range statement in /etc/ltsp/dhcpd.conf must be 192.168.160.2 192.168.160.253 or smaller.08:58
moquistIt would be good to leave room for some static hosts on at least one end, of course.08:59
moquistThere's no reason to make your DHCP range vastly larger than the largest number of hosts you expect.08:59
moquiste.g., if you know you only have 20 thin clients, I would set your range to something like:08:59
moquistrange 192.168.160.50 192.168.160.100;08:59
moquistbut remember that addresses in that range will also be used by *any* DHCP clients on that network, not just thin clients.09:00
jonfhancockAh yes.. My printer and so on09:00
moquistso if you have 20 TCs but groups of 75 with laptops come in for meetings sometimes, you have to account for that.09:00
jonfhancockok09:00
jonfhancockI'm not too worried about that.09:01
=== moquist nods
moquistI'd rather over-explain than under-explain. :)09:01
jonfhancocknaturally09:01
jonfhancockSo here's what I have in dhcpd.conf09:01
jonfhancockauthoritative;09:02
jonfhancocksubnet 192.168.160.0 netmask 255.255.255.0 {09:02
jonfhancock  range 192.168.160.50 192.168.160.100;09:02

jonfhancock  option routers 192.168.160.254;09:02
jonfhancock  option subnet-mask 255.255.255.0;09:02
jonfhancock  if substring( option vendor-class-identifier, 0, 9 ) = "PXEClient" {09:02
jonfhancock    filename "/ltsp/i386/pxelinux.0";09:02

jonfhancock  }09:02
jonfhancock  option root-path "/opt/ltsp/i386";09:02
jonfhancock}09:02
moquistjonfhancock: it's considered polite not to paste stuff in IRC; use something like http://rafb.net/paste/09:05
jonfhancockSorry.09:05
moquistjonfhancock: I'm nice. Other people would kick you from the channel (probably not this one, though) for doing that. :)09:05
moquistjonfhancock: NP.09:05
jonfhancockI'll remember that09:05
moquistWell, I don't have privs to kick you here, even if I were mean. So you're very, very safe. :-D09:05
jonfhancockhaha09:05
stgrabernever try doing that on #ubuntu-devel or #ubuntu :)09:05
jonfhancockempty promises... ;)09:06
moquistYeah, it can really cause a lot of confusion in high traffic channels.09:06
jonfhancockI'm sure.  although, I don't plan on spending much time in #ubuntu-devel...09:06
=== moquist is now looking at the paste
stgraberbtw, this dhcpd.conf seems to be ok, now you'll need to put 192.168.160.254 on your NIC (if not already done) and restart dhcpd09:06
jonfhancockThat's what I've done.09:07
moquistjonfhancock: looks OK; do you have 192.168.160.254 set up to do routing to the Internet?09:07
jonfhancockcan you elaborate?09:07
moquistjonfhancock: http://rafb.net/p/nkEKaa53.html09:07
moquistjonfhancock: it only matters if you'll have thick-clients on the network, too09:08
moquisti.e., if a machine gets its DHCP from your server, it will try to get to the Internet through 192.168.160.254, which must then serve as a gateway09:08
jonfhancockI haven't, but all my clients should be thin09:08
moquistok, then no problem.09:08
moquistyou don't actually need the option routers line at all in that case. (but I would leave it, anyway)09:09
jonfhancockk09:09
jonfhancockIs that something I could do for good measure, without risk of making my problem worse?09:10
jonfhancockjust in case I do have a thick client one day09:10
moquistshouldn't really make a difference; I wouldn't mess with it unless you need to09:14
jonfhancockk09:14
moquistwhat I sent is only a runtime thing, BTW. you'd want to take care of ip_forward in sysctl.conf, and probably save the iptables with whatever mechanism does that.09:15
=== moquist doesn't remember OTOHH
moquistogra: ping?09:15
jonfhancockso to sum up, dhcpd.conf is configured ok, and the nic is asigned 192.168.160.254, but dhcp3 still fails to start.09:15
moquist?09:16
moquistthat's odd.09:16

moquistLaserJock: k09:18
LaserJockmoquist: so is there only one perl script that is executed?09:19
moquistLaserJock: so the right thing to do is spread the .pm files and the data dir out on the system?09:19
moquistLaserJock: Hmm. No. There are a small handful of them.09:19
LaserJockmoquist: one thing you can do, I think, is house them in /usr/share/<packagname> and just symlink from /usr/bin/ to there09:19
moquistLaserJock: I think that sounds like a straightforward option; I'll do that for now.09:20

moquistjonfhancock: note the inet 192.168.2.113 line under ath0; you have no inet line under eth009:22
jonfhancockI don't know09:22

moquist"totally model". Hmm.09:24
