Centos7 hostname change not working

[brehuffm]

running latest version of FOG server and client here…so looking thru the client side fog-log (file attached)…and yes the change hostname is enabled both globally and in the host configuration. I also found other Ubuntu issues where they had to check the AD box that says “Name Change/AD Join Forced reboot?” and this also didn’t seem to help.

It seems that this maybe the issue…
snip from log:

@brehuffm Here we see the important part of the log file:

12/5/2019 7:05 AM Middleware::Authentication ERROR: Could not authenticate
12/5/2019 7:05 AM Middleware::Authentication ERROR: Value cannot be null.
Parameter name: authority

Some Linux distros use mono version that is causing the problem. We have fixed the client library but haven’t been able to push out a new release yet. Find details about this here: https://forums.fogproject.org/topic/13070/client-not-authenticating and https://forums.fogproject.org/topic/13374/fog-client-under-ubuntu-18-04-authentication-error-could-not-authenticate

In short: Download Zazzles_fixed_Linux.dll, stop FOGService (systemctl stop FOGService), rename /opt/fog-service/Zazzles.dll and put the new Zazzles.dll in place. Then start the FOGService again and watch the log.

Zazzles.d

Sebastian-Roth, you were spot on. Worked like a champ. Many thanks. Is it safe to assume that this fix will be in the next Fog image? Thanks again for the quick response. Brett

Not sure what you mean by fog image. The next fog-client version will have that fix included, sure…
