Cannot get TFTP File not found using dnsmasq
-
I am setting up FOG at home to make a second job I have easier. Setting up new computers for the company my wife works for’s customers. I have Ubuntu 14.04 installed and the latest SVN of FOG, 3443. I have dnsmasq installed and systems boot to the Network fine and are looking on the correct system for the file. I have gone through the troubleshooting at, https://wiki.fogproject.org/wiki/index.php/Troubleshoot_TFTP, and everything checks out fine other than tftp get from my windows machine… When I try I get C:\WINDOWS\system32>tftp 192.168.1.77 get undionly.kpxe, tftp: can’t write to local file ‘undionly.kpxe’. See below my lstp.conf and output of ls -laR /tftpboot.

What concerns me is why can’t you get a file through TFTP using windows.
You verified that TFTP is running? Firewall is off (on Ubuntu and Windows) ?
Just to clarify and make sure, the command shouldn’t include that path into system32… you just need to use the last part of what you posted:
[CODE]tftp 192.168.1.77 get undionly.kpxe[/CODE]Can you post a picture of the exact error you’re seeing? Thank you.
-
Yes, TFTP is running. Linux and Windows Firewalls are off.
The command I am using is exactly what you posted and is in the screenshot below, I just Marked the whole line since the error was on the next line under the Windows Shell Path.

Can you try this?
[CODE]tftp 192.168.1.77 get undionly.kpxe %HOMEPATH%\Downloads\undionly.kpxe[/CODE]
I’m not positive, but the command you’re running might be trying to put the file into system32 (because that’s your current directory), and Windows might be stopping that. You’re error “can’t write to local file ‘undionly.kpxe’” suggests this, so better to use an explicit destination path.

Oh… (it’s been a long day)
about the file not found error on booting to network via FOG using dnsmasq,
I think you just need to copy undionly.kpxe to undionly.0
dnsmasq adds a .0 to the end. This is dnsmasq’s thing, FOG doesn’t maintain dnsmasq, it just uses it. so…
[CODE]cp /tftpboot/undionly.kpxe /tftpboot/undionly.0[/CODE]It’s highly annoying, it’s also well known about.
It’s mentioned here: https://wiki.fogproject.org/wiki/index.php/Using_FOG_with_an_unmodifiable_DHCP_server/_Using_FOG_with_no_DHCP_server#DNSMASQ_settings_for_iPXE -
or Link the file
sudo ln -s -r undionly.kpxe undionly.0But that shouldn’t be the problem, since you’re explicitly stating the file you want via TFTP. I’ll go with the idea its a permissions problem on the Windows side.
Running as a regular user:
C:\Users\Trevelyan>cd C:\Windows\System32 C:\Windows\System32>tftp 10.1.6.1 get undionly.kpxe tftp: can't write to local file 'undionly.kpxe'Running as admin:
C:\Windows\system32>tftp 10.1.6.1 get undionly.kpxe Transfer successful: 103273 bytes in 1 second(s), 103273 bytes/s -
Okay, I will check when I get home. I am in Eastern time zone and my wife showed me the time right after my last post last night so I went to bed.
I also found an issue with dnsmasq on my Linux box that was causing me to not have an internet connection. I don’t think it was the cause since my test system was going to the correct system to try and grab the file, but I havn’t fixed it yet.
I will fix the dnsmasq issue and test tftp as admin on my Windows box.

@Timtrag12
With the dnsmasq issue, I bet its because of the way it seems to kill dns lookups. In short, you just have to change the order of interfaces in /etc/resolvconf/interface-order - just put eth* first in that list. Give that a go, restart the server, and see what happens.

Thanks for the starting place. I was just gonna experiment when I got home tonight.
