In the previous part, we set up DHCP, TFTP and RARP servers and successfully booted the OpenBSD ramdisk install kernel on old Soekris hardware over the network from a repurposed Cisco IDS. In the last part of this series, we will add NFS shares to the mix and install OpenBSD to them, making our PXE clients fully functional and then set up a minimal router and a caching DNS to provide our clients with working internet access.
In the first part, we became familiar with the hardware we’ll be working on and gathered the needed information. In this part, we focus on making PXE work up to the point we’re able to get to the boot loader and load a kernel.
Does anyone remember Soekris Engineering, the company that made network hardware and somehow also audiophile equipment? The first part of the company has unfortunately closed down in April 2017, while the latter still persists today. However, we won’t be focusing on high-fidelity audio in this guide, but rather on squeezing the last bits of life out of their old products.
