I seem to have somewhat successfully created a custom task there is 1 issue with it so far:
When the task is complete, it is still stuck in “Active Tasks”. How does one fix this?

@Sebastian-Roth I was hoping for a completely new one. Mine is less of a script and more of a realm join in a bash file

Does anyone have a working script to join clients to a domain with realm join? Mine keeps failing post deployment

Is there anyone out there who has had success with the FOG client on Linux?
And had a very easy and comprehensive way to deploy Linux images and rename them/Join them to the domain post deployment?
Please share working scripts if you have them.

@justeverything Do you have the working version of this?

@george1421 so I now have the line you specified end with “,255.255.0.0” because without it, the second subnet wont pxe boot.
When I restart our lab of 26 machines all at once, all but 3 stop at “enter tftp server”
Our other lab I attempted a restart all at the same time but it did not seem to have an issue but the PCs were just slightly more staggered on the restart. But I still believe that this shouldn’t have been a problem in either lab.

@george1421 I removed the second dhcp range line and now clients on the second subnet won’t boot at all

@george1421 I removed the second line for the other subnet and will try again when i get to work monday to see if that fixed it.
The line was a second dhcp-range

@george1421 so now, sometimes it will say “please enter tftp server”
So far it only seems to do it if 20+ pcs reboot and once. And at that point many of them do it. Always random though.

@george1421 now its working just fine for some reason…I didn’t make any changes.

@george1421 said in Clients will not consistently boot into PXE environment - dnsmasq:

@jhumpf Did you use my config file referenced in the first link to setup your dnsmasq server?

Yes. Plus one line for my second subnet

@jhumpf said in Clients will not consistently boot into PXE environment - dnsmasq:

Sometimes the clients boot right into the PXE environment, much of the time they will give the following errors:
PXE-E52: proxyDHCP offers were received. No DHCP offers were received.
PXE-E55 ProxyDHCP did not reply to request on port 4011

This would indicate that dnsmasq DID respond because it knows there is a proxyDHCP server. It would only know that because it was told there was one.

Does this issue happen on one subnet more than another?

Do you have more than 1 dhcp server on your network?

Finally, can you successfully predict when this error will happen, such as if we setup wireshark we could capture it not working?

I am not positive about the multiple subsets. I believe so but I cant be certain.
I can ask about multiple dhcp servers. And I’m not sure about predictions. We probably can capture it with wireshark.
I tried doing it from the server and I didn’t see anything noteworthy but maybe I’m missing something

I need some urgent help.
I am using dnsmasq so we do not have to alter our DHCP server. It is available to both subnets.
I am unsure if this inconsistency is on both subnets because there are not enough clients on the one to do accurate testing.

Sometimes the clients boot right into the PXE environment, much of the time they will give the following errors:
PXE-E52: proxyDHCP offers were received. No DHCP offers were received.
PXE-E55 ProxyDHCP did not reply to request on port 4011

This does work sometimes but it is REALLY inconsistent and yesterday took dozens of reboots and many failed attempts for them all to come up for multicast and unicast when I do them separately.

I have the exact config for dnsmasq as the install for CentOS 7 FOG wiki says to have.

Please help?
It has been like this ever since it was installed.

Did you resolve this? I have an image I created on a UEFI machine and I need it to boot on BIOS/Legacy booting machines
