Reposting here since want to know how a Linux computer handles this scenario.

Consider a Ping Request packet arriving on a computer with 2 NICs (multi-homed PC). The packet is received on 1 of the interfaces. Now the computer has to send the Ping Response packet. To fill the source IP and source MAC address the computer does which of the following?

• Computer first determines which interface should be used as the egress interface by looking at the Destination IP address. Destination IP address was taken from source IP address field of Ping Request packet. Once it determines egress port, it will enter that interface's IP and MAC address in the Ping Response packet.
• Computer takes the destination IP and MAC address of the Ping Request packet and just flips them over to fill source IP and MAC address in Ping Response packet.

Basically what it says in the title. I did a lot of searching in Internet. I think small form factor computers are mt best bet. But I still feel they are costly for my purpose.

I am going to be running some ansible playbooks periodically on the machine. SBCs i looked at either had very high specs for this use case and thus higher price or they had other fratures i dont want like - wifi, graphics card etc.

I am preferring enterprise hardware because this would eventually be used in business where people will not settle for anything less.

I have started trying out xcp-ng as an alternative to VMWare solutions for virtualization. Currently I have setup 3 VMs of xcp-ng v8.2.1. I have also setup Xen Orxhestra build from source.

I wanted to try out XOSTOR solution for shared storage. I have followed instructions mentioned in the forum: https://xcp-ng.org/forum/topic/5361/xostor-hyperconvergence-preview

I am getting errors at the storage creation step which is step 4 in the forum post I linked. The error I get is "Missing python module 'linstor'."

Anyone has got xcp-ng working with XOSTOR here?
