Impossible to boot on PXE......

[arnaudrigole]

@Sebastian-Roth

Thanks for your reply!

Ok, i used filters “tftp && bootp” however …? Which one i must use to do a better capture ?

MSFT 5.0 ? Strange… i just set up “MAC Adress” “is equal :” in my dhcp strategy as you can see:

Any idea for my second problem?
I re-ran the installfog.sh , defined IP to 10.1.11.170, IP of the storage node and i looked at all parameters on FOG interface > FOG Configuration > FOG Settings

And my PC still try to open http://10.1.18.180/fog/service/ipxe/boot.php… ?

But the filter you should use in wireshark is " bootp || tftp".

Look for FOG Configuration -> FOG Settings -> Web Server -> FOG_WEB_HOST

[Wayne Workman]

Also, this might be a good time to introduce this: http://sourceforge.net/p/fogupdateip/code/HEAD/tree/

Works great on CentOS 7 and Fedora 23 Server.

It basically allows your FOG server to be assigned any IP from a pre-existing DHCP server, and it auto-configures the server and dnsmasq for you every time the ip changes.

Hi !
Thanks for your reply!
value in “FOG_WEB_HOST” is the true ip… no problem.

I’ll update to trunk today
does FogUpdateIP works on Debian 8 jessie?

@arnaudrigole For your second issue take a look at /tftpboot/default.ipxe on your FOG server and edit as needed.

Thanks Wayne, I must have been half asleep when writing the post about wireshark filters. Sure it ought to be bootp || tftp (not &&)!! Can you please try again? Keep your wireshark ready, set with those filters, then bootup the client (cold boot!) and see if you get more packets.

Ok, i go on it and i’ll post the reply fast

Ok, after i’ve edited “default.ipxe” it works, my PC boot on pxe interface
i tried to upload the image of PC

So: I created a task to upload the current image from the PC to my FOG server, it begins, then it reboot after 1 minute without error message, i’ll post a pcap too.
Edit: Here is the pcap, protected by pw i’ll send you in private

EDIT IMPORTANT: I defined the storage type in my image settings to “multiple partition image / not resizable” and it seems working; partclone is currently running on my computer.

For the first problem, here is the pcap file i recaptured with filter bootp || tftp

Really appreciate your active help, from all you

No, not yet anyway. I need to build a Debian server to mess around with.

@arnaudrigole As I already explained things usually should go like this: PC boots, NIC sends PXE DHCP discovery and gets back PXE information (next-server and filename). Then it loads the file via TFTP and executes it. FOG uses iPXE as a second stage. So far so good. From what I can see in the PCAP file this is perfectly happening for you. Cannot see any issues there. But then I see four DHCP requests from iPXE (which was loaded and executed as a first stage). But there is NO response from the DHCP server.

Either the DHCP server does not like the DHCP request (maybe some DHCP option that iPXE is sending) but I kind of doubt this as others seam to be able to use windows DHCP server without a problem.
Or it could be because of spanning tree (STP). The NIC is reset a couple of times while this PXE process is going on. If your switch has STP enabled but port fast is not used this might cause exactly the issue you see: https://wiki.fogproject.org/wiki/index.php/STP/Portfast/RSTP/FMSTP

So it times out on the TFTP part? Change from undionly.kpxe to undionly.kkpxe

[arnaudrigole]

@Wayne-Workman
It will be helpful

@Sebastian-Roth
There is no spanning-tree in our configuration actually, i tried to boot with 2 differents computers (Latitude E5510 and Opx390) on the same port to do the packet captures. The first arrives to boot then find the pxe file, and upload its image, but the second has no response from DHCP ? That’s strange ^^ Both have the same configuration in dhcp strategy, i’ll try to erase/recreate the host on it

@EAHarvey
Hello!
What does it change??

[EAHarvey]

@arnaudrigole When i was having tftp timeouts this is what I changed to make it work. The iPXE is the open source PXE boot environement that FOG uses. Let me see exactly what the difference is between kpxe vs kkpxe. @Senior-Developers may be able to shed a bit more light. I would love to know exactly also.

Wireshark filter bootp && tftp is great for this
