I have installed Virtual Box on host Ubuntu 12.04 and RHEL 5.5 as client. I need to do file sharing between em.

And I can access the shared folder of Ubuntu from RHEL using Shared Folder Service builtin VB.

Shared Folder

And now I want to access a file that is on RHEL but the thing is this I can't access it.

And I can't even ping any.

Ubuntu HostName:: Inspiron-N5110 RHEL Hostname :: Redhat

Ping from ubuntu to Redhat

umair@Inspiron-N5110:~$ ping Redhat

ping: unknown host Redhat

Ping from Redhat to Ubuntu

ping Inspiron-N5110

ping: unknown host Inspiron-N5110

Network is NAT

Network Image

Actually that is quite strange that I can't even ping Host system itself means when i do ping Inspiron-N5110 it replies that ping: unknown host Inspiron-N5100 and same is the case for Client System.

You have selected NAT (see screenshot 2). Change it to bridged and select your network interface. Then both machines are in the same network and can ping each other.

Sorry it didn't work Network Adapter changed to Bridged and NW connected to eth0. But no use. Any other suggestion – Umair Mustafa Oct 13 '12 at 11:40
you can't ping a nat interface. Select bridge mode and select the correct interface. don't forget to check your firewall in the guest machine and host machine. In redhat don't forget to check apparmor/selinux too – Antoine Rodriguez Oct 13 '12 at 13:28
One more thing I would like to add also set the PROMISCUOUS MODE to ALLOW ALL. – Umair Mustafa Oct 14 '12 at 6:38
