Hi there,

I have installed the Oracle virtualbox on my win 7 laptop.
ifconfig show an ip address 127.0.0.1 in the virtualbox. I have a few questions where the first is the most important.

1) How can I change this ip address to a "normal" one 192.168.x.x? I would think in a fixed way.

2) I have read it is possible to assign automatic ip address through DHCP. How can I do it?

3) In these threads, they are talking "eth0", "eth1", "tap0"... What are these? How to create them? There are no such names in my network adapter.

4) By the way, the reason I want to change this ip address (127.0.0.1) is that by using sqlplus from the host I get this message "ORA-12541: TNS: No listener". I have read other thread which seems to linked this error message to this "non-normal" address of 127.0.0.1. Any other thoughts to solve this problem will be very much appreciated. I can ping 127.0.0.1 from the host and ping the host 192.168.1.1 from the guest virtualbox.

Many thanks in advance,

VirtualBox is the name of the application program. The virtual machines which you create are called virtual machines or guests, not "virtualboxes".

127.0.0.1 is a loopback address. It means "this machine" and cannot be accessed from any other machine (real or virtual). If you ping 127.0.0.1 from the host you will get a reply because it will reply itself! The reply will not come from the guest.

If you want the vm to get a 192.168.1.x address from DHCP you will need to set the networking in the vm to bridged. It will then behave as if it was another machine on your local LAN.
