Thanks. I was just wondering. Before I recreated the /home/fog/ directory the image capture process kept giving errors. So I was thinking that there might be some script or something in that directory. However, now after just manually recreating that directory image capture is working just fine again. I had run the installofg.sh and I had thought that it would have recreated the fog home directory, since it did detect that the directory was missing. I didn’t read the screen carefully enough to see that it was directing me to manually delete and recreate the fog user. Recreating the home directory did the trick through.

Thanks for confirming that I am not missing anything critical in that directory though.

Hello,
I needed to repartition my FOG server and wound up corrupting the /home/ partition. I deleted and recreated the partition and the fog user directory. Is there supposed to be any scripts or anything in that directory? Additionally, in my moving items around while out of space in my /images/ partition, I think I would up deleting some files in the /images/postdownloadscripts/ and the /images/dev/postinitscripts/ directories.

So the question is, what should be in those directories and where can I download the initial contents for those directories? I ran the installfog.sh script again and it looked like it might have been doing that, but the contents of the directories didn’t change. Maybe nothing is missing after all.

Thanks, Tim

As another test, I booted the test client laptop into Windows and successfully tftp’d the undionly.kpxe from the fog server. So network-wise everything looks correct.

@Sebastian-Roth I remembered that a while ago we got a 10/100 monitoring hub specifically for this task. And I was actually able to find it, right where I thought it should be. Amazing.

I put the captured content at: output.pcap

From my quick viewing of the output, the DHCP process completed properly, sending the correct values for option 66 and 67. However, there is no tftp traffic. I ran the capture again adding the or host <fog ip address> or host <client ip address> (since it always gets the same one), but got no additional packets.

Hopefully this tells you something. I’m guessing that this is a client NIC issue.

Thanks, I’ll see what I can do. The issue being that the Fog server and my DHCP server are in the same VLAN, but my booting client is in a separate VLAN. I have the helper address configured as we’ve needed for DHCP to function. So with that DHCP stops being a broadcast and gets directed to the DHCP server, so the Fog server won’t see them. I think I have an old 3Com 10Mbps dumb hub here that I could plug the client in through to capture the traffic. Will need to do some scrounging though.

Thank you for the response. At the end of the day yesterday with getting nowhere I decided to rebuild the server, since it was new anyway. I rebuilt it using CentOS and the TFTP is transferring properly now. I am able to connect from several different computers and get files from the Fog tftpd.

Now I need to get the DHCP PXE boot figured out. Using http://blog.thecybershadow.net/2013/01/10/dhcp-test-client/ I see that the DHCP server is passing the proper data for options 66 and 67. However I still am getting a “TFTP open timeout” error on my PXE clients. They are all old (2010 or older) Lenovo laptops with Intel gigabit Ethernet NICs onboard. I am going to see if there is a firmware update that might help.

I might be posting again to see about getting this figured out, but I’ve got a few things I need to try before getting to that.

Thanks again for the response,
Tim

Server

Description

I have DHCP settings configured but I am having issues getting tftpd working. I have disabled SELinux and the firewall to get those possibilities out of the mix. I have gotten to trying to just use a command-line tftp client to transfer files. Every time I try I get the message:Error code 0: Permission denied

I get that Permission denied message even when I try to “get” a file name that doesn’t exist.

I’m wondering what the next step to try would be.

Any insight would be appreciated.

Tim
