Question Problem on assigning static ip address.. RHEL 5 as guest OS on Virtualbox


Hi folks,

I'm just new to Linux and I need some help.

I setup a small network at home that comprise of:

1. Desktop
OS = Windows XP
IP = 192.168.1.101
Using Virtualbox, I installed RHEL 5 as guest OS.
Virtualbox host-only Network: IP=192.168.56.1

2. Laptop
OS = Windows XP
IP = 192.168.1.102
Using Virtualbox, I also installed RHEL 5 as guest OS.
Virtualbox host-only Network: IP=192.168.56.1

The router's address is 192.168.1.254 and is connected to the internet.

With those settings, everything is working fine. The RHEL5-Desktop can connect to the internet, and to 192.168.1.101(Desktop XP) and 192.168.1.102(Laptop XP) through smbclient. The RHEL5-Laptop can also do the same. Both RHEL5-Desktop and RHEL5-Laptop are using DHCP.

The problem is I want to connect RHEL5-Desktop to RHEL5-Laptop through ssh. I tried assigning static IP to either RHEL5-Desktop or RHEL5-Laptop with the router's address as default gateway and the connection became pretty messed-up. I tried other things like leaving the default gateway blank or changing the Virtualbox host-only to 192.168.56.2 but still no luck.

I hope somebody can give me a detailed instruction on how to do this correctly. I'd really appreciate it.

Change the virt box net configuration such that the guests are on bridged adapters and have (DHCP) addresses on the 192.168.1.0/24 network. Without the bridged network, even though the guests appear to be in the same subnet, they are not really on the same physical network segment. And since the router's interface that you want to use as their default gateway is on a different subnet, that won't work either.

Thanks for the reply.. I'll get back as soon as I'm finished trying that solution. Thanks again

That worked perfectly fine. Thanks for lending a hand. I have another question though, the Virtualbox host-only network, what is that for? Please explain to me in details cause I'm just a newbie. Thank you so much!

This has a great explanation of why the host only network exists.
