Reach host truenas from VM

[boistordu]

Hi,

I’m new to truenas so I don’t have the right reflexes I guess just yet.

i wanted to mount somenfs shares from my truenas host and it doesn’t work.
timed out.

so I tried to reach the host from within the vm with ssh and it doesn’t work either.

the vm are created in truenas.

truenas host is otherwise accessible.
Vm also.

they are on the same subnet than the host so it means it is bridging ?
and if that is the case, I was wondering if it was the same phenomenom that in linux where you use a bridge virtual controller and therefore the vm can’t contact the host?

thanks in advance

Okey so by filtering it through tcpdump I can see that ssh packets are going through vnet0 and bridge0
But not through vtnet0 which is the main interface of truenas.

what I can see it’s that in the web GUI, the listened interface is vtnet0.
So my question is, is it because of that setup ? And how do I authorize the vm which are using vnet0 apparently to also be able to contact the host ?

so that I can be sure that Ican Contact the host from the vm ?

So from the tcpdump I've made
it becomes clear that truenas is not responding on vnet0 for the ssh connection. Which is a bit sad that you can't contact the host from the VM through SSH.
The host is receiving request on vnet0 and is a link created for each VM .
there is even ACK sent to the VM

But no connection is made. So I don't know if it's because turenas doesn't answer correctly to the request or something else.

The problem is that I have the same kind of problem apparently with any shares I try to make and which should be reachable through the vm :

Code:

doing parameter server string = %h server (Samba, Ubuntu)

I wrote about the same problem a few days ago and got no replies. https://www.truenas.com/community/t...eeing-smb-share-of-host-truenas-system.92142/

Still no suggestions on how to do it. :(
