sudo update-rc.d minidlna defaults
This should add the service to the automatic startup system. But if you get:
System start/stop links for /etc/init.d/minidlna already exist.
Do the command
sudo update-rc.d minidlna enable
P.S.: For further detail look at the man page for update-rc.d by typing the command man update-rc.d
The best way to login to a guest Linux VirtualBox VM is port forwarding. By default, you should have one interface already which is using NAT. Then go to the Network settings and click the Port Forwarding button. Add a new Rule:
Host port 3022, guest port 22, name ssh, other left blank.
or from command line
VBoxManage modifyvm myserver –natpf1 “ssh,tcp,,3022,,22”
where ‘myserver’ is the name of the created VM. Check the added rules:
VBoxManage showvminfo myserver | grep ‘Rule’
That’s all! Please be sure you don’t forget to install an SSH server:
sudo apt-get install openssh-server
To SSH into the guest VM, write:
ssh -p 3022 user@127.0.0.1
Where user is your username within the VM.
