VM SSH

Hello,

I discover your system with joy.
I am trying VMs at home, ...

There is one thing that I cannot do however, it is to connect in SSH to the virtual machines.

Could you tell me how I can activate SSH on my virtual machines please?
(Ps: they are activated in the distribution services installed on the Vm)

Thank you.
Have a good day.

This works out of the box If the service is activated in the VM.

so for example, if I want to ssh into my vm inside proxmox. Which IP will provide for the

ssh root@xx.xx.xx.xx

for it to work

The IP you or our DHCP server assigned to it. And you have to install an SSH server in the guest as well. This works exactly the same as on a real machine and isn't specific to Proxmox.

I have SSH server installed on the VM (It's an Amazon linux2 guest OS, so SSH come pre-built). when i try to SSH from the host to the VM

root@dgt:~# ssh ec2-user@192.168.1.10
ssh: connect to host 192.168.1.10 port 22: No route to host

My goal is to be able to SSH into the VM from outside of the proxmox host.

That error message means what it says. There is no route to the VM from the Host. It is a network problem. Maybe your VM is on a different subnet than the host, or you have VLAN's set up, or you turned on the PVE firewall, or something else you are not mentioning.

To start, please post the output of "ip a" for host and guest in code tags.

For the proxmox host:

root@dgt:~# ip a

I cannot highlight or copy the guest outputs from the gui. but below is a screenshot, I hope it suffices

Your host and the VM are on entirely different networks (10.111.92.23/24 and 192.168.1.10/24). Assuming that the rest of your network uses 10.111.92.23.xxx/24, you would change the VM to be on that same network. I do not know anything about "amazon linux 2" so I can't tell you how to change the IP of that (this is one of the things that vary between distributions of Linux).

Here is a tutorial on how IP addressing works:
