I’m guessing you deleted your message because you found the .fogsettings file after all.

As for your DHCP concerns, this might be because your router is also handing out DHCP information.

If you cannot modify your router’s DHCP settings to hand out TFTP/PXE bootfiles and if you cannot turn it off, then you should like into using ProxyDHCP

Tywyn

@Quazz You are right. I was looking in /etc/fog (for what reason ever :))
There is no router involved.
I have the fog-server connected to a switch (cisco SF100D-05) and my test-client connected to the same switch.
Strange thing is: in the beginning I got ip-adresses on pxe boot via dhcp.
Now not anymore. But: starting Windows and setting network to use dhcp immediatly gets an ip address.
dhcp-Server is the fog-server

@Tywyn Would it be possible to provide a screenshot of the client failing to get an IP?

@Quazz
Cannot do a screenshot, but will type in, what it says

After booting windows now, it does not offer an IP-Address either anymore, although it did 20 Minutes ago:

@Tywyn This might be relevant for your situation:

https://wiki.fogproject.org/wiki/index.php/Not_passing_PXE,_or_ProxyDHCP...NO_PROBLEM_Cisco

Either that, or try and get a “dumb” switch and see if that works.

Tywyn

Replaced the cicso switch by an tp-link switch (Easy Smart Switch TL-SG108E).

Same thing. No ip-Addresses anymore …

Quazz

@Tywyn Can you communicate from the client to the server? (ping and ftp for example)

Another possibility for why it’s not working might be the firewall on debian. You could turn it off for testing.

https://forums.fogproject.org/topic/6162/firewall-configuration

Explains a bit how to set it up so you can still use it.

Tywyn

I think, the network-card in the fog-server is broken. No more connects into the 192.168.100.0/24 network anymore (ping). Firewall configuration is unchanged.

What was very strange before: I tried to capture a host, that I successfully registered before.
Started well and then from the sudden the transmission of the image stopped after 850 MB. To make sure that it is not a client issue I changed the client to another machine I then I did not get any ip-Adresses anymore from pxe boot and later also in Windows.

@Tywyn In regards to the second nic. Is the FOG server a physical machine or a VM? If it is physical, is this a server with 2 built in nics or did you add the second nic as an add in card? If the nic is an add in card is it a generic one or is it a name brand one like intel or broadcom?

This situation seems very strange in that the problem is rolling from one thing to the other. A bad nic might give us that experience, but something tells me there is another thing going on here. Unless you use one of those cheap network card, I suspect the issue is somewhere else.

Tywyn

Ok. Problems that came up with the dhcp-issue were related to the network-card in the fog server.
Strange thing, since the network card worked for some minutes and then stopped even pinging, which worked before.

Changed the network card, built an image from one machine an cloned it to another machine. Everything worked fine.

No comes the fine tuning.

Thank you for your help everybody!

Tywyn

@george1421 It is a physical machine with 1 onboard NIC and (now) one TP-Link networkcard.
Works fine now.

Thanx for the help!
