two virtualbox (internal-network) setup

[Dick Dowdell]

Engineer Amer,

I just setup 2 VMs with both a NAT and a Host-only adapter.  I ended up
with VM1 at 192.168.56.101 and VM2 at 192.168.56.102.  Both VMs can see the
other.  I did not alter any of the preassigned IP addresses.  I then
installed openssh-server on each of the VMs and had no difficulty ssh-ing
between them.  I can also ssh to each of the VMs from the host using the
192.168.56.10n addresses.

Are you setting up both the NAT and Host-only adapters?  Without the NAT
adapters, I don't believe you'll be able to update either of your VMs.
Perhaps you could send the results of an ifconfig command for both VMs.

Regards,
Dick Dowdell
