[][COLOR=#000000][FONT=Arial][SIZE=15px][COLOR=#000000][FONT=Arial][SIZE=15px](Here comes the controversial change, get ready…) Move away from PHP. I don’t do much work in PHP any longer, I don’t want to start a flame war, but there are somethings I love about PHP (ie: it’s a psuedo functional language and FP is good.) but there are also things that I really don’t like about PHP, and those I won’t go into here. I would prefer to rewrite the FOG front-end is a statically typed language like Scala with Play2 potential or even Java (I know I said a bad word).[/SIZE][/FONT][/COLOR][/SIZE][/FONT][/COLOR]

Just an opinion. If you want help with FOG, how many PHP developers / programmers are out there versus “Scala with Play2 potential” developers? IMHO, if you change away from PHP mid-stream, and have to re-write everything from scratch, you might be setting up the project for failure.

FYI, here are the lines I had to add to the iPxe config to deal with the other TFTP image server on my school network:

#already had this line in place
set next-server 10.xxx.xxx.xxx

#additional lines to make sure correct boot image and image server are used
set filename pxelinux.0
set proxydhcp/filename pxelinux.0
set proxydhcp/next-server 10.xxx.xxx.xxx

Well, it only took 3 months, but I’ve solved this one… or at least I know what the problem is.

REVIEW:
I was using iPxe CDROMs for the machines that connect to the FOG server. I do this because my school district isn’t “friendly” towards my FOG server, and won’t let me make any sort of changes to the network, or have my own DHCP server.

iPxe worked great until December/January. I went away for two weeks, then came back to a non-working FOG server. Specifically, I could not UPLOAD images to the FOG server any more.

TODAY:
Today, after playing with iPxe for a few hours, I noticed that the config utility was showing a “second” TFTP server on the network with a different IP and a different default “filename” setting than mine. Basically, while I was setting iPxe correctly, some of the config settings from the “other” TFTP server on the network were being mixed in with my iPxe settings.

BOTTOM LINE:
I was logging into my FOG server OK, TFTP was working OK, the FOG server is configured OK, but when it came time to grab “config.cfg”, everything fell apart. Unknown to me, I was trying to grab config.cfg from the OTHER TFTP SERVERS directory structure somehow.

SOLUTION: I will have to add additional iPXE “set” or “clear” commands to make sure the settings from the other TFTP server are not in place before booting the pxelinux.0 image.

Thanks BryceZ…

Yea, I have considered rebuilding the server. I may have to if I can’t solve this soon.

I’ll comb the configs one last time, and 777 everything and see if that helps. If not, I have an old backup that dates to WAY before the issues started, so I may have to spend a day and rebuild everything. The sad part is that it worked great, I left for two weeks, and now it’s hosed.

Another concerns is that the district I work for controls the network infrastructure, and they may have changed the switches or DHCP server or something.

Another option would be to build a box just for FOG.

Anyway, thanks for two helpful responses

Can anybody point me to documentation on checking for configuration issues? Any sort of list as to what folders I should check?

Ok, I’ve been messing with this for a couple of months now, and I still can’t get it to work. I’ve put off imaging my lab multiple times. I’m getting a bit desperate here

• I’ve reinstalled FOG multiple times, deleting anything that even remotely has FOG written anywhere on it.
• I’ve tested TFTP from a Windows box with the FOG user, it works fine, pxelinux.0 is visible, etc.
• I’ve tested FTP from a Windows box with the FOG user, it works fine, the “default” config file is visible, etc.
• The Fog server is installed fine, all is well. I can create tasks and they show up in the tftpboot folder with the proper MAC address associated with them.

And yet, I still get the “unable to locate configuration file” error, over and over.

ANY suggestions, any stab in the dark, anything… I’m getting to the point where I will have to revert to Clonezilla to get this lab imaged. Is there a listing of what the file permissions should be that I can compare to?

Here’s what I have:

Some tftp servers use /var/lib/tftpboot as home, try copy the files there and see if your client can find them.

Thanks… tried that but it didn’t work.

You will need to look harder.

Fair enough, I will look harder…

However, I only came here after reinstalling FOG 3 times, tweaking the FOG user passwords multiple times, changing paths many times, and changing permissions on multiple folders multiple times. So I’ve been trying pretty hard to solve this issue on my own

Thanks for the reply. I already have a task in place, and it is showing up properly as a file named with the MAC Address of the machine. The config file is in place also. I guess I’m going to have to go over the permissions with a fine toothed comb and try different things. Attached is a screen shot showing the folder/files/permissions for default on my Ubuntu machine.

Man, what an odd turn of events. I came back from a 2 week vacation at work, only to find that my server:
(1) Was “unable to connect to TFTP server”. Fixed that by a couple of reinstalls of FOG until I got it right.
(2) Attempted to UPLOAD an image, and recieved an “Unable to locate configuration file” message.

I boot off of CDROM using iPXE, which worked from August until now. Here’s basically what my boot looks like. This is not my actual, but an example copied from elsewhere that is the same…

Seems to load pxelinux.0 OK, but then stalls every time. My IP hasn’t changed,
and otherwise FOG seems fine.

Any suggestions?
Thanks in advance,
