Virtualbox connect from host to guest via ssh and enable internet on guest

  1. Open Oracle VM Virtualbox Manager

    virtualbox_manager

  2. Place the cursor on the machine that you want to configure and press the button Settings.
    -> Network -> Adapter 1-> check Enable Network Adapter -> in Attached to choose NAT.
    -> in Advanced section -> press Port Forwarding  -> in Port Forwarding Rules, press addition button ->
    Fill the rule , by the following way:
    Host IP: (leave blank)
    Host Port: 22   (or any port that your host has free)
    Guest IP: (leave blank)
    Guest Port: 22

    vm_settings
    rules

  3. Start up the VM and connect to the guest using ssh.
    Hostname: localhost (or your machine name)
    Port: 22 (it is the same that we have indicated during rule configuration field Host Port)

    putty

  4. If you are not using proxy, than you can think that the post finished for you. You can connect to the guest from os and also you have an internet on your guest.

    But if proxy is used then you should configure parameter http_proxy.
    You can enter this variable information in every user’s  ~/.bash_profile or you can do it globally in /etc/profile file.

    #add the following entry in profile file

    [root@oracle01 ~]# vi /etc/profile
    export http_proxy=http://proxyservername.domain.ge:8080
