How to use Linux DNS Server for windows machine

[bangshws]

Hi guys,
My situation is like this:
I'm using Windows XP
I installed VMBox and a Virtual Machine which is an Ubuntu Server
On Ubuntu Server, I installed Apache and Bind9. I also changed /etc/resolv.conf to use the DNS installed.

Testing:
On Ubuntu Server, I can ping 192.168.56.102(ubuntu server)
On my windows XP, I can open web browser at ( h t t p:// )192.168.56.102

But I can't use ( h t t p:// ) example.com (which was configured in Bind 9 to point to 192.168.56.102)

Can someone help me please?

Kind Regards,

you need to set the dns server for your internet connection to be the ubuntu server's IP

Yes I already set the dns server for my windows xp to point to 192.168.56.102 but when I used nslookup: it showed that it couldn't connect to that one so it used the secondary DNS Server

Possible issues:
1a) the bind daemon is listening only on localhost
1b) the bind daemon restricts access
2) the connection is blocked by either the windows or linux firewall

You can check listening daemons with:

netstat -tunlp

And/or look at the connections

First: tcpdump -i eth0 port 53

Then: try another nslookup from the windows box

Dear the following snippet is what I obtained from netstat -tunlp
. Can you please review and tell me what the problem is since I don't know what exactly I need to look for?

Thanks so much,

I know the reason.

I have 2 internet connection: 1 is Virtual box , 1 is real Ethernet.

I configured the DNS server for the real Ethernet card. That's why.

I should have configured for the Virtual Box card.

Thanks,
