Hi,

I checked the config file (ltsp.conf) and it includes the following lines:

[CODE]# The boot filename.
dhcp-boot=pxelinux.0[/CODE]

so it looks like it is not a capitalisation issue. The ltsp.conf file is as per the guide I followed:

[INDENT=1][URL=‘http://www.fogproject.org/wiki/index.php?title=Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server’]http://www.fogproject.org/wiki/inde...le_DHCP_server/_Using_FOG_with_no_DHCP_server[/URL][/INDENT]

Is there anywhere else I need to check that it is all lowercase?

Thanks,

Alan.

Hi,

I do not have access to change the router providing DHCP here, so I also installed dnsmasq on the Ubuntu Server, and that also seemed to work fine. I followed this guide:

My understandig is that the PXE-E53 error indicates that the client received a reply to its DHCPDISCOVER message, but the “boot filename” information was missing in the reply to the client:

[INDENT=1][url]http://www.bootix.com/support/problems_solutions/pxe_e53_no_boot_filename_received.html[/url][/INDENT]
[INDENT=1] [/INDENT]
From what I can tell, the “boot filename” option is present on the fog server, and its value is set to the filename of the boot loader (PCELINUX.0), however, I could be wrong!

Thanks for your help,

Alan.

Hi X23,

Thanks for your help.

1. Permissions on tftpboot/pxelinux.cfg/ are rwx/r-x/r-x so readable and executable to everyone. Do I need to give write permissions to everyone too?

2. I cannot find any file on my system, from / all the way down, starting with “01-”. I could not find any file beginning with “01” that was followed by either the string “mac-address” nor by any string that could be a MAC address. I used:

[INDENT=1]sudo find / -name 01-* -type f[/INDENT]
[INDENT=1]sudo find / -name 01* -type f[/INDENT]

3. I restarted the tftpd-hpa service thus:

[INDENT=1]sudo service tftpd-hpa restart[/INDENT]

Having done (1) and (3) as above, I re-tried the PXE boots, but I am still getting the same PXE-E53 error.

Thanks,

Alan.

Hi,

I have setup Ubuntu Server 12.04.2 LTS with fog - all seemed to go to plan, and the web server works and I can log in. I followed this guide:

[url]http://www.howtogeek.com/57601/what-is-network-booting-pxe-and-how-can-you-use-it/[/url]

I do not have access to change the router providing DHCP here, so I also installed dnsmasq on the Ubuntu Server, and that also seemed to work fine. I followed this guide:

[url]http://www.fogproject.org/wiki/index.php?title=Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server[/url]

All good, including restarting dnsmasq, but when I try to boot using PXE, I get Error 53:

[INDENT=1]PXE-E53 - No boot filename received[/INDENT]

I have tried booting from both a physical machine, and also from a freshly created VM (VirtualBox 4.2 on Ubuntu Desktop 12.04.4 LTS) but they both return the same E53 error.

I would appreciate some assistance in troubleshooting as I don’t know where to go from here.

Thanks,

Alan.
