Woah! Thanks for taking the time to write the detailed response. Will take a look at the source code. Really appreciate the effort ❤️

Standards are set of rules. But still different vendors implement them separately. For e.g. TCP/IP stack implementation is a bit different in Windows and Linux but end user generally never realises this because it's close enough that things still work. I want to know what is the sequence of events when Linux creates a Response packet for a ping Request it received.

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.

This weirdly makes sense to me. Not long ago would have done the same.

I have one in the lab at office. Were abt to be thrown out. Nursed it back to life somehow. Good to play around plus company foots the electricity bill so win-win.

I know. I felt while writing the post that this feels wrong writing those words in same sentence. The scenario is that we would deploy the hardware on customer premises so it has to be supported and very reliable(hence enterprise grade). But i personally think that all enterprise grade hardware is way overkill for running ansible playbooks. So was trying to see if there is an intersection point between these opposite requirements.

Budget is not an issue actually. This is going to be deployed for customers but i want to it to be as cheap aspossible to get them maximum value for their money. Software stack is going to be minimal. Probably alpine linux or ubuntu server. Spec wise i think even an i3 level cpu is fine. Ram 8gb, hard disk 256 gb ssd should be more than enough. Dont require any fancy wireless stuff like wifi and Bluetooth.

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.

One of the KDE devs sharing why it is 'Mega Release' from their perspective. Quite interesting to hear about all the things that go on in the background in software development. https://tube.kockatoo.org/videos/watch/e6e8f177-22f1-432a-9c7f-ab76b17a5b54

Figured it out. I had created 3 VMs but was trying to created shared storage between 2 xcp-ng instances. I assumed that this can be done and the 3 instance will only act as witness without contributing to the storage.

After going through many replies on the forum thread I understood that you need minimum 3 hosts participating in the storage. Modified my setup to match the requirements (was easy since they are just VMs) all the instructions worked correctly.

The error about missing linstor python module was that I hadn't installed necessary packages on 3rd host in the pool since I assumed it doesn't require XOSTOR instructions to be run on it since it would not be participating in shared storage. This is my understanding though and I can be wrong.

Having written above I think I can still have only 2 hosts participating in storage but just need to install necessary packages on third host also. Will try and see how it goes.

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?

Notally on Android. Simple and light weight. Has widget support too.

What replacement options you are looking at?

Depends on where in the world you are too. See the video for a example. https://www.youtube.com/watch?v=3Hge8FyrZ5A

So yeah, you numbers might vary but the point is correct.
