In reply to Xavery.

Heh… good way to find solution for me is to ask someone the question. Nobody may answer but I _always_ find solution by myself 🙂
In this case solution is to add: `inst.noverifyssl’ option to APPEND row.
Maybe will be useful for next PXE warriors 🙂

Sorry for noise in ether.

Hi there.
Tutorial is very usefeul, but… Does anyone know how to force PXE to work with HTTPS with no check certificate? I have used something like that:

APPEND (…) inst.repo=https://server.with.local.mirror

And curl complies that cert is unknown. In fact it is and cannot be another. I know i can use “-k” option to curl but where to place it? Is there any other option id PZE menu file, that allows https connections with no-check-certificate.
I’m asking here, because I’ve found nothing about that. I someone knows the answer, please help me.

Regards

hi pradeep

Thank you very much for your prompt response. The previous error has been fixed but now I have another problem.

The client pxe remains in the option to choose language. Then, I must press “continue” manually, and I must select hard drive and install.

Can you help me to make it automatic?

In reply to Rodrigo. Hi Rodrigo, Please make sure the virtual machine or physical server has been assigned at least 2 GB of RAM.
