PXE Boot Issues after running the Mobile Fog Management script

[george1421]

Well I can tell you what’s wrong, but I’m not sure if the script is working as it should. We may need to get @Wayne-Workman involved to take a peek at the script.

To fix your issue edit the /tftboot/default.ipxe file. That has a hard coded IP address in there. That is probably where the old IP is hiding.

@chris178 TFTP server address is different from the HTTP IP address shown in the picture. Please check all the FOG settings in the web GUI.

I checked all of the web settings before I made the post. I’ll see about editing the file tomorrow. Thanks @george1421

@george1421 You were right on the money. I changed the IP in the file and it booted straight into FOG. Is there a way we can fix this? @Wayne-Workman

[Wayne Workman]

@chris178 Of course. Firstly, no idea why it’s not just working for you… that’s weird. The cron event that gets created by the installer is supposed to run a script every few minutes that corrects everything automatically (including default.ipxe file).
Couple things:

1. Make-Fog-Mobile sets up dnsmasq to operate in proxy mode. This means you should not (nor need to) setup your permanent DHCP servers to serve out anything special - dnsmasq takes care of all this.
2. There should be a root crontab event to run a script in /opt/fog/utils/MakeFogMobile/MakeFogMobile.sh every 3 minutes.
3. The log file for the script is here, and it’s very exact and human-friendly: /opt/fog/log/makeFogMobile.log

Did you run the installer?

[chris178]

@wayne-workman Yes, I ran the installer. I looked at the log file and this is what it had: “The path for IP was not found. Exiting” I’m not too familiar with programming. I did look at the script and tried to find where it was getting that information from, but I got lost pretty easy. Can you point me in the right direction or take a look at it? Thanks.

@chris178 That is highly interesting coming from a CentOS 7 server… ip is a standard command on CentOS 7 minimal and should be present.

So, looking here: https://github.com/FOGProject/fog-community-scripts/blob/master/MakeFogMobile/MainScript.sh

Line 31 gets the absolute path of the ip command.

Line 51 then calls a function to check and see if $ip is empty or not. The function is at line 38.

What is the output of this command:
command -v ip

On my CentOS 7 testbox, this is what I get:

[root@centos7 ~]# command -v ip
/usr/sbin/ip
[root@centos7 ~]# 

I’d expect similar from your server.

[chris178]

@wayne-workman I got exactly the same output. So now what?

[chris178]

@wayne-workman Let me ask this. Is there a certain directory that I should run the installer from? I just ran it from a folder on the desktop, unassuming that it might need to be in a certain location to pull the correct IP.

[Wayne Workman]

@chris178 I was able to fix the issue. If you can do a git pull from the fog-community-scripts directory on your server, you’ll get the latest copy - then rerun the installer and everything should work.
