| paolob | Hi guys! | 03:08 |
| paolob | Anyone could tell me what config file should I modify in order not to have the "no free leases" error? thank you! | 03:09 |
| paolob | mhz, do you remember it? | 03:10 |
| mhz | paolob: hi | 03:10 |
| paolob | hola mhz | 03:10 |
| mhz | hola | 03:10 |
| mhz | I have never had such error, sorry :) | 03:10 |
| paolob | How many clients do you work with? | 03:11 |
| mhz | paolob: I wish I had 'clients' to work with and test. So far, a small 1GHz Celeron and 2 thin laptops | 03:11 |
| paolob | mhz, it's an error due to exhausting the IP range permitted by dhcp | 03:12 |
| mhz | ohhh | 03:13 |
| mhz | how many clients? | 03:13 |
| === zakame [n=zak@ubuntu/member/zakame] has joined #edubuntu | ||
| paolob | mhz, what do you think of the delay the clients have when performing the nfs mount before running the services? did you see it? | 03:13 |
| paolob | mhz, I have 40 clients (don't you remember?) | 03:13 |
| mhz | oh, tes! | 03:14 |
| mhz | t =y | 03:14 |
| mhz | paolob: breezy or dapper? | 03:14 |
| paolob | breezy | 03:14 |
| paolob | mhz, do you have that delay with your laptops? | 03:15 |
| mhz | I know breezy take loooong to load | 03:15 |
| mhz | yup | 03:15 |
| mhz | Dapper loads clients lot faster | 03:16 |
| mhz | afaik | 03:16 |
| mhz | but haven't had the chance to test it yet | 03:16 |
| paolob | :-) | 03:16 |
| mhz | paolob: does your /etc/ltsp/dhcpd.conf mention anything about leases? | 03:16 |
| === mhz phone | ||
| paolob | mhz, no. ogra had told me I have to change a parameter that governs a lease's life | 03:19 |
| mhz | ohh | 03:19 |
| mhz | well, he's the Mr. Edubuntu | 03:20 |
| paolob | the strange thing is he told me to change a parameter in /etc/dhcp3/dhcpd.conf, but apparently that config file is superseded by /etc/ltsp/dhcpd.conf in /etc/init.d/dhcp3 | 03:21 |
| mhz | oh, that makes sense | 03:22 |
| mhz | paolob: what IRC client do you use? | 03:22 |
| paolob | xchat | 03:23 |
| mhz | do you have logs 'enabled'? | 03:23 |
| paolob | I enable it right now | 03:24 |
| mhz | $ grep -B 7 -A 3 -i leases ~/.xchat/xchatlogs/..... | 03:25 |
| mhz | oh | 03:25 |
| mhz | you hadn't ?? | 03:25 |
| mhz | then I have no clue how to help you unless I tell you google for 'dhcp leases' :D | 03:25 |
| paolob | I enabled it right now | 03:26 |
| paolob | what did you want me to see? | 03:26 |
| mhz | or 'comment out' (#) the lines about 'leases' in the file ogra mentioned | 03:26 |
| mhz | paolob: I thought you could have check the logs of that chat ;) | 03:26 |
| paolob | but the fact is that that config file isn't used by dhcp3! | 03:27 |
| mhz | ? | 03:27 |
| mhz | well, I am pretty sure /etc/ltsp/dhcpd.conf is the file we use | 03:28 |
| paolob | ok | 03:28 |
| paolob | but than, what do I put there? | 03:28 |
| mhz | but I see no 'lease' lines in my dhcpd.conf | 03:28 |
| === mhz phone again! | ||
| paolob | that's the fact! | 03:30 |
| paolob | should I add it? | 03:30 |
| paolob | default-lease-time 600; | 03:30 |
| paolob | max-lease-time 7200; | 03:30 |
| paolob | these should be the lines, ogra told me to put 200 instead of 600 | 03:31 |
| paolob | mhz, do I think I can add it to /etc/ltsp/dhcpd.conf ? | 03:33 |
| paolob | s/I/you/ | 03:34 |
| mhz | what's the worst thing that can happen if you do? :D | 03:34 |
| paolob | that's true! | 03:37 |

| edubuntu | Back with my yesterday thin client booting problem. Errors begin when commandline: Begin: Running /scripts/nfs-premount... | 03:47 |
| edubuntu | Done. | 03:47 |
| edubuntu | nfsmount: need a path | 03:47 |
| edubuntu | Begin: Running /scripts/nfs-bottom... | 03:47 |
| edubuntu | Done. | 03:47 |
| edubuntu | Done. | 03:47 |
| edubuntu | Begin: Running /scripts/init-bottom... | 03:47 |
| edubuntu | Done. | 03:47 |
| edubuntu | mount: Mounting /root/dev on /dev/.static/dev failed: No such file or directory. | 03:47 |
| edubuntu | mount: Mounting /dev on /root/dev failed: No such file or directory. | 03:47 |
| edubuntu | Target filesystem doesn't have /sbin/init. | 03:47 |
| edubuntu | Then: BusyBox v1.00 bla-bla-bla. | 03:47 |
| edubuntu | /bin/sh: can't access tty; job control turned off | 03:47 |
| edubuntu | Where is the solution? | 03:47 |
| edubuntu | What could be wrong with my nfs? | 03:48 |
| ogra | did you rebuild the client chroot as i told you ? | 03:51 |
| edubuntu | I did simply ltsp-build-client, but you advised to delete a directory...which one? | 03:52 |
| ogra | the one where the client chroot rersides | 03:52 |
| ogra | /opt/ltsp/i386 (the one ltsp-build-client told you when you reran it that this will likely cause problems) | 03:53 |
| edubuntu | No it didnt say nothing | 03:53 |
| ogra | if you already have that dir there is a big warning | 03:54 |
| edubuntu | Does these operations affect my running VXL terminals? | 03:54 |
| ogra | no idea | 03:54 |
| ogra | i dont know VXL terminals apart from the stuff you told me | 03:54 |
| ogra | likely it wont | 03:55 |
| ogra | since they seem to have a local OS | 03:55 |
| edubuntu | These have built-in opsys and start in kiosk mode and make then a connection to the server with XDMCP. There is no more choice for protocol. Only RDP and XDMCP. I assume these dont netboot but simply connect X-server. | 03:57 |
| ogra | yup | 03:58 |
| edubuntu | So it is harmless to delete /opt/ltsp/i386???? But really I didnt have any warning when rerunning ltsp-build-client... | 03:59 |
| edubuntu | What kind of login screen I should arrive. Like gdm or similar. Is it graphical login or commandline? | 04:00 |

| edubuntu | The problem actually starts with the line: mount: Mounting /root/dev on /dev/.static/dev failed: no such file or directory then mount: Mounting /dev on /root/dev failed: no such file or directory Target filesystem doesnt have /sbin/init. I just looked in the /etc/mkinitramfs/scripts folder - all the scripts folder are empty. Is it a nfs problem? The problem was similar before I touched to ltspadmin. | 04:16 |
| === irvin [n=irvin@ubuntu/member/irvin] has joined #edubuntu | ||
| ogra | did you rebuild your client chroot ? | 04:18 |
| edubuntu | Which command it is? | 04:19 |
| ogra | ltsp-build-client after you cleaned up | 04:19 |
| edubuntu | Ok i will try and 1st i backup actual /opt/ltsp/i386... | 04:20 |
| ogra | no point in backing up a broken chroot... but as you like | 04:21 |
| === zakame is now known as Ibalon | ||
| edubuntu | Should i remove only /i386 folder or /data and pkg_cache folders too? | 04:24 |
| ogra | whats that ? | 04:25 |
| ogra | i have no idea how you got these folders there, they are not from edubuntu ... | 04:25 |
| === pitux [n=pitux@185-240-90.adsl.terra.cl] has joined #edubuntu | ||

| edubuntu | If all is done is it necessary to restart service(s), daemons? | 04:35 |
| ogra | nope | 04:35 |
| ogra | if all is done you should be able to boot | 04:36 |
| edubuntu | ok ...it is configuring now... | 04:37 |
| edubuntu | So i made a thin client boot and got exactly the same result. | 04:45 |
| edubuntu | I have dhcp server in another PC. Maybe it is affecting the process. Missing a line in /etc/dhcpd.conf?? | 04:47 |
| ogra | err | 04:48 |
| ogra | you did read the InstallNotes ? | 04:48 |
| ogra | dont edit /etc/dhcpd.conf | 04:48 |
| ogra | its not used at all | 04:49 |
| edubuntu | Yes I did it 100 times. | 04:49 |
| ogra | and nope, you cant run two dhcp servers in one subnet | 04:49 |
| edubuntu | I printed out also ubuntu thinclient-howto | 04:49 |
| ogra | thats useless for edubuntu | 04:49 |
| ogra | all stuff described there is done during install | 04:50 |
| edubuntu | in edubuntu thinclient there is nothing to do- only configure PXE booting? | 04:50 |
| ogra | nope, only edit the /etc/ltsp/dhcpd.conf file | 04:50 |
| ogra | to match the right subnet | 04:50 |
| ogra | and restart dhcpd indeed | 04:51 |
| ogra | then it runs | 04:51 |
| ogra | but if you have a second dhcp server, either shut down the existing one, or dont use the one in edubuntu and configure the existing one for netbooting the thin clients | 04:51 |
| ogra | you cant use two dhcp servers | 04:52 |
| edubuntu | We have usual address space 192.168.0.1 (firewall and DHCP) up to 255. Edubuntu server is 40. My thin client is 59. When booting it clearly shows that it will boot to 40. May be I transmet the dhcpd.conf file? | 04:53 |
| ogra | is the exisating one a linux server ? | 04:54 |
| edubuntu | yes | 04:54 |
| ogra | then you could try to transfer the data into the config, yes | 04:54 |
| ogra | you'll need the next-server directive to point to the nfs server though ... | 04:55 |
| ogra | the easier way would be to shut down the existing one and just use the edubuntu dhcp with a range from 1-254 ... | 04:56 |
| ogra | or what ever range you like | 04:56 |
| === paolob [n=donPaolo@pri-214-b7.codetel.net.do] has joined #edubuntu | ||
| edubuntu | You were right, Ogra - when I stopped the existing DHCP server it booted up correctly. Superbe... Thousend thanks.... | 05:21 |
| ogra | :) | 05:22 |
| ogra | there are workarounds on wiki.ltsp.org to run two dhcp servers on different ports in one network, but thats highly complicated to set up, i wouldnt suggest it if you can migrate to a single one | 05:22 |
