Can you include steps for x86 boot

[Istech-Tech]

Can you include steps for x86 boot it also seem dhtest wont extra image

[uedvt359]

Have you tried PXEClient for dhtest -o?

[Istech-Tech]

yes does not seem help or missing something i think image just call /image but am not sure

[uedvt359]

Please write down all the steps you did, including the output. I can't help you with the information you've given so far

[Istech-Tech]

basicly run net install cli on ethernet interface with -i and the router os npk winch if boot machine pxe on that interface x86 it boot try to ru dhtest -i interface name -v not tcpdump show images

/images i have try to user curl tftp to get image curl tftp:// ip address /image > netinstall_x86

[Istech-Tech]

mind you i did not notice it said it always name linux.arm try that not but does not apear to be working

[Istech-Tech]

still missing somethign maybe some stupid i dont know i think i have format right

[Istech-Tech]

I dont if help but tcpdump show file as just /image

[uedvt359]

OK, maybe they use image as the bootfilename on x86. Can you post your tcpdump? That would help debugging this tremendously. As you said, you should then be able to download it with curl -v tftp://127.0.0.1/image > netinstall.x86. What does curl print (with -v to show the logs) when you try that?

I cant seem to get curl grab it just says transport error not sure if image should be call image

I found some time today to reproduce the issue. send the following dhcp request: sudo dhtest -T 5 -o "PXEClient" -i lo -c 93,hex,0007. Notably, it requires option 93, documented here: https://www.rfc-editor.org/rfc/rfc4578#section-2.1

it does not matter if you tftp-get /image or linux.arm - they both return the same file (I suspect that the tftp server doesn't even look at the filename)
