[Bug 316217] Re: LTSP on top of Ubuntu 8.10 desktop does not boot
As no problem was found concerning the LTSP code, I'm marking this bug as invalid. So, maybe there is a need for a practical mini-howto treating troubleshooting on the individual file level -- along the lines you helped me. Jack, the misconfiguration problems that you had are not usual LTSP problems, as the installer scripts automatically configure the necessary files. It's been a while since you upgraded, so we can't be sure which was the original problem, if any, and which problems were caused by manually editing the configuration files. But for most people LTSP works out of the box. The client works perfectly now. I can also print on the server- connected printer from the client.

Re: [Bug 316217] Re: LTSP on top of Ubuntu 8.10 desktop does not boot
Hi Alkis 1) I meant to say: I ran ltsp-update-image (no change), and ltsp-build- client. 2) netstat -nap | grep :2000 executed on the server without any message. 3) nbd-client 192.168.0.1 2000 /dev/nbd0 -persist on BusyBox gave the following message: Error: Connect: Connection refused 4) There may be a discrepancy in file location here. I observed that a boot message on the client reports filename: /ltsp/i386/nbi.img However, a file search for nbi.img turned up only the following two locations for these links to the executables: /opt/ltsp/i386/boot and /var/lib/tftpboot/ltsp/i386. No file /ltsp/i386/nbi.img was found on the server! BTW, I have upgraded Ubuntu version by version since breezy. I wonder if this could have been a cause of a possible location problem!

Hi Alkis: Thanks for your prompt reply. I will indeed try the freenode link. However, here is the current situation: 1) The rootserver was already 192.168.0.1 2) and so was the nbdserver; it was exactly like your text! 3) For completeness sake, I retyped the bootmessages on the client for so far they did not roll away. Here they are: - . . . Loading vmlinuz... Loading initrd.imgready [5.821127] IO APIC resources could not be allocated. Loading, please wait...

(I don't look forward to that, but it will a useful education!) In the meantime, I followed your instructions. These resulted in a major step forward. Starting the client brought up the Ubuntu graphic loading screen. However, this was quickly followed by text.

Dear Alkis:
I have not yet solved this problem. In the mean time I have upgraded to
v. 9.04 Jaunty. I did remove and reinstall ltsp on the jaunty
upgrade. I also followed your points 1) thru 3). No results yet. In
fact, I think I took a step backward! gPXE 0.9.6 fails now with the
following messages on the client:
Waiting for link-up on net0 ... ok
DHCP (net0 00:50:ba:5e:79:4c) connection timed out (0x4C106035)
no more network devices
--- BTW 00:50:ba:5e:79:4c is the NIC on the client. ---
I have the following in my system. Do you see any obvious errors?
The dhcp3 files (/etc/ltsp/dhcpd.conf and /etc/dhcp3/dhcpd.conf) both
contain:
subnet 192.168.0.0 netmask 255.255.255.0 {

filename /ltsp/i386/pxelinux.0;
} else {
filename /ltsp/i386/nbi.img;
}
;}
--- Note: it seems that the reinstallation did not affect these files.
---
The files /etc/resolv.conf and /etc/resolc/com contain:
search happy # my hostname
nameserver 205.171.3.65 # ISP
nameserver 205.171.2.65 # ISP
nameserver 10.0.0.2
Could you give further guidance what to try next? Many thanks.

This error is normally due to a firewall blocking the tftp server from firing off.

Re: [Bug 316217] Re: LTSP on top of Ubuntu 8.10 desktop does not boot
No success yet! Please bear with me -- my knowledge of linux is superficial. So I'll report what I did. Synaptic identified that my only current firewall is ipkungfu. I issued sudo ufw disable. The response was ufw -- firewall stopped and disabled on system startup. I rebooted the server after this message. In the past I have upgraded and updated Ubuntu many times, and I have used different firewalls (e.g. guarddog and firestarter, which together with ipkungfu still hang around in /etc/init.d). I attempted to look at the iptables to somehow verify that the firewall was inactive. Alas, I was not able to get the iptables displayed. I decided to accept the ufw response. In any case booting the client with gpxe failed in exactly the same way as before. BTW, my Zoom DSL-modem/router has an internal firewall -- can I assume this has no effect here? Thereafter I issued sudo /etc/init.d/tftpd-hpa restart. (note: I could not find tftp-hpa, I figured tftpd-hpa would be correct.) This command was accepted by linux. I then issued sudo ps aux. I could identify /usr/sbin/init in the output, but I could not find anything like tftp ot tftpd-hpa there. I don't know what that signifies. Somewhere I read that tftpd-hpa automatically starts on booting by init.d. So again I went ahead with booting the client with gpxe. And again booting failed in the same manner as before. There is another thing that still bothers me in the original bug description. Booting from filename /ltsp/i386/pxelinux.0 tftp://192.168.0.1//ltsp/i386/pxelinux.0 ... Connection timed out Could not load tftp://.while pxelinux.0 on my server exists only at /opt/ltsp/i386/boot/ and /var/lib/tftpboot/ltsp/i386/ This seems to be a discrepancy. Should I be bothered by that? Nubae wrote: This error is normally due to a firewall blocking the tftp server from firing off. If it is not due to that, make sure the tftp server is running by restarting it (sudo /etc/init.d/tftp-hpa restart) and check ps aux to see it is running. More than likely though, this is due to a firewall issue. -- LTSP on top of Ubuntu 8.10 desktop does not boot https://bugs.launchpad.net/bugs/316217 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
