FOG Server host registration issues

george1421

@TTellez What precisely do you have setup in dhcp for dhcp options 66 {next-server} and dhcp option 67 {boot-file}?

And secondly what device is your dhcp server for your network?

If you have to enter the ip address of the fog server for tftp to work then something isn’t right with your dhcp server/environment.

TTellez

@george1421 Thanks for the reply George. How do I check that?

george1421

@TTellez You installed the FOG server right?

When you installed the FOG server, did you tell the installer to manage dhcp or did you answer No?

One of the requirements for pxe booting is having a dhcp server on your network. Some people use fog for dhcp if its on an isolated deployment network. Or others use microsoft dhcp server or some other third party dhcp server.

The question of how do I check, depends a lot on what you have today.

TTellez

@george1421 and the FOG server is my DHCP server

george1421

@TTellez I know I’m belaboring this point, but its important to have a clear picture.

Before fog you didn’t have a dhcp server on your network, or is FOG on an isolated deployment network.

The issue I’m trying to drive at is to ensure you don’t have 2 dhcp servers on your network where your computers are pxe booting. Bad things will happen if you do.

@TTellez said in FOG Server host registration issues:

@Wayne-Workman Updated to the 1.3.5 official.

The Model of the host is a Dell E5570

Now that I have updated from the RC, it is asking me to enter the tftp server?

Usually, when the tftp server is requested, you have two or more dhcp servers serving the subnet and at least one of them isn’t configured correctly.

Follow along with George, he’s on the right path and more available than me.

TTellez

@george1421 Yes, told the installer to manage DHCP

george1421

@TTellez will you post the contents of this config file? /etc/dhcp/dhcpd.conf

This is the dhcp server configuration file running on FOG.

<edit> also post the results of ps aux|grep 67

Not sure if this is right.

@TTellez Well this one is really wrong. Not sure where my head was when I gave you that command, but the initial command was wrong. Lets try netstat -an|grep 67 That should show us if the dhcp server is running on your FOG server.

Your dhcp config file looks right. Just to confirm the following

Your fog server is at IP address 10.1.1.164 and it is a static IP address. To see the current IP address of your fog server ip addr show
You have no other dhcp server on the 10.1.1.x/24 subnet?
Your router off this network is 10.1.1.1?
Is this an isolated imaging network?

TTellez

@george1421

FOG server address is 10.1.1.164 or localhost
Hmmm, to answer 2,3, & 4 in the same one there IS another DHCP server. Yes, the router is 10.1.1.1, and NO this isn’t isolated, unless I remove the net connection, and use localhost

EDIT: in typing this response I realized what you were asking. So I removed the external network, created the isolated imaging network, used localhost instead of the IP and BOOM we are imaging.

TTellez

@george1421 better?

@TTellez I’m not sure what you changed in the second config file.

But again what I’m trying to drive to ground is if you have 2 dhcp servers on the same network. We’ve established that the FOG server is one dhcp server. The question is there a second one? We can make FOG work if there is a second one (or original one) we just need to know it. You have now confirmed that this is not an isolated network.

I keep asking if you setup a deployment network just for FOG? That was to try to determine again, is there another dhcp server some place (maybe your ISP router??)

In your config file for the dhcp server, I see your dhcp range is .10 to .254, but your FOG server is at .163 (inside your dhcp range, which is a bit suspicious since you said it was static).

It sounds like you unplugged something and now imaging works. Did you unplug your router? The localhost statement has me a bit confused.

It sounds like you have imaging working now, but is this how you want it to be long term? My next step was to have you run a tcpdump to capture the pxe booting process that would tell us what is going on the wire.

Wayne Workman

@TTellez said in FOG Server host registration issues:

option domain-name-servers 127.0.1.1;

That is surely incorrect.

TTellez

@george1421 The switch we were using also had a network connection connected to it. So when I pulled the connection, instead of using the IP address we used localhost.
