Connecting to your VM over SSH
Find the VM address and SSH port on the service page. Most VMBargain images use a non-default port shown there; always use the displayed value.
Connect with a key
ssh -i ~/.ssh/id_ed25519 -p PORT root@SERVER_ADDRESS
For an IPv6 literal, use the address without square brackets in the SSH command:
ssh -i ~/.ssh/id_ed25519 -p PORT root@2001:db8::10
Connect with the initial password
ssh -p PORT root@SERVER_ADDRESS
Accept the host key only after checking that you are connecting to the expected address. A timeout normally indicates routing or firewall trouble; “connection refused” means the host answered but nothing accepted that port; “permission denied” means the SSH service was reached but authentication failed.
