Fog client not renaming computers

[Omar.rodriguez]

Server

• FOG Version: 1.3.2
• OS: Ubuntu 16.04

Client

• Service Version: 0.11.8
• OS: Ubuntu server 16.04

Description

Deploying a ubuntu server 16.04 image to machines does not rename the host. For example if I named the first computer PC1 where the ubuntu image was captured from any machines i image with that ubuntu image will also be named PC1. The client will then not recognize the other PC’s when it’s time to auto-reboot when a imaging task is created.

@Omar.rodriguez, alright that’s what I suspected when I saw all of the macs. The problem is your installations share the same virtual mac addresses. You can fix this problem by telling FOG to ignore those macs. To quote @Tom-Elliott from https://forums.fogproject.org/topic/8315/response-error-multiple-hosts-returned-for-list-of-mac-addresses

The fix for this is to add that mac address to the FOG Configuration Page->FOG Settings->FOG Client - Host Register->FOG_QUICKREG_PENDING_MAC_FILTER, you can add the whole mac address or a part of the mac address. Using the “partial” address (usually the first 3 or 4 hex pairs) means it is going to filter anything that matches the partial part. This is comma separated. e.g. (00:01:0F,00:02:03:04,00:05:ab:af:ad:ac).

@Omar-rodriguez please provide the fog.log file for the problematic host. It can be found in /opt/fog-server/fog.log.

@Omar.rodriguez Also make sure that in Fog Settings that ( FOG Client - Hostname Changer ) is checked.
And let us know if it is.

@Raymond-Bell It’s very possible that the hostname-changer is unchecked, it’s been happening to me lately, but the problem is that it might somehow be unchecking itself. I have it to be checked by default, but when I added a new client, it had all services off which caused me to have some problems with machines joining the domain with their default name. So just something to keep in mind. I don’t know what’s been causing that though.

[davidedpg10]

@Raymond-Bell I have now confirmed it, for whatever reason, reimaging a computer causes all of the services to become unchecked, it explains why the computers have not been renamed correctly prior to running snapins

It’s not this. Works on any other image just not the Ubuntu one. The settings are checked as they should be.

I will be post the fog.log in a bit

[Raymond Bell]

@Omar.rodriguez Thank you for checking please upload log file when you get chance, also miss read i was thinking this was a Windows image not a Ubuntu image

@Joe-Schmitt @Raymond-Bell

here is the log file 0_1486064852118_fog.log

@Joe-Schmitt Since this is Ubuntu image i know this is old but i am wondering if he is needing something like this to change the host name on Ubuntu computer

@Omar-rodriguez could you try hitting Reset Encryption Data on the host in the web portal? Also is there a reason why so many network adapters (virtual or real) are present on this machine?

[Omar.rodriguez]

@Joe-Schmitt @Raymond-Bell just want to clarify my concerns:

1. The hostnames aren’t changing on Ubuntu 16.04 with the client installed on the image.

2. When a new imaging task is created for one of the Ubuntu 16.04 machines it doesn’t auto reboot (yes the setting in fog settings is checked), which means I can’t remotely image machines as I could have to physically be there to reboot the machines.

Sorry if I wasn’t too specific in my OP

[Joe Schmitt]

@Omar-rodriguez correct. That’s why I asked

could you try hitting Reset Encryption Data on the host in the web portal? Also is there a reason why so many network adapters (virtual or real) are present on this machine?

What you’re describing is usually just a symptom of a bad authentication handshake.

[Omar.rodriguez]

@Joe-Schmitt Where can i find this in the fog web portal ? BTW the machines are all CLI non have the ubuntu GUI.

Also the reason why they have so many network adapters is because we have various Juniper virtual devices running with the machine.

[Joe Schmitt]

@Omar-rodriguez it can be found by either selecting a host or a group from the web portal:

[Omar.rodriguez]

@Joe-Schmitt Tried that and nothing happened

We also tried more troubleshooting. This is what we were seeing

Are the mac addresses the problem? is there a place we can change the mac address in a config?

OG Client

Hey Joe just want to give a huge thank you for helping me out. This solved the issue!

For future reference if anyone has the same issue. This is what we were doing on our end. We are running Ubuntu 16.04 server with KVM. We have multiple virtual network devices which created multiple mac addresses. In return trying to deploy the same image from one machine to others caused a conflict with FOG which made the client not work on the machines. Following what Joe quoted tom on fixed our issue. In my instance using the first 3 hex pairs in FOG_QUICKREG_PENDING_MAC_FILTER solved the issue and the client is working as it was intended to
