Hi,guys:
I am trying to connect to a NFS-filesystem on a CentOS 5.3 i386 guest system. The host system is CentOS 5.4 x86_64. I set up the NFS server correctly and rpcinfo is also ok inside the guest system show.
The problem is, I can't connect to, or see the open port from the outside. I use the Host-Only network setup with VirtualBox 3.1.0, the ip address in the guest system is 192.168.56.101 . and the host system ip address is 192.168.7.67
When I mount the directory from the guest system via NFS, the result is the following : "mount : 192.168.56.101:/xx failed , reason given by server:Permission denied"
I hope one of you can give me a hint in which direction I should continue my efforts.
Thanks in advance,,,

If you already can ping the nfs server, then you should check this: 1. nfsd service 2. open port on iptables 3. /etc/host.allow or /etc/host.deny
You can check share folder from nfs client with command: showmount -e ip.nfs.server If the folder appears, then you can start to mount that otherwise you should check your /etc/exports again.

Thanks for your reply~
I think my problem could be is how to create the iptables that could let the NFS server access into the host system.
The guest system is CentOS 5.3 i386 . The ip address is 192.168.56.101 with the eth0 interface And the host system is CentOS 5.4 x86_64, its ip address is 192.168.7.67 and its route information is the following :
root@xxx: route -n 192.168.7.0 xx xx xx eth0 192.168.56.0 xx xx xxx vboxnet0
I run this iptable rule in the guest system which configured the NFS server,
iptables -A INPUT -i eth0 tcp -s 192.168.7.67 --dport 111 -j ACCEPT
Then : when I run "showmount -e 192.168.56.101" and the directory appears, but run the "mount -t nfs 192.168.56.101:/xxx /media" in the terminal , the output is still that message: "mount : 192.168.56.101:/xx failed , reason given by server:Permission denied"
So is it my iptables rule wrong? Or how to write the correct the rule ?
Thanks in advance~.

What is the contents of /etc/exports on the server?
James Pearson
The contents of /etc/exports on the server is the following :
/home/test 192.168.7.67(rw)
Is there anything error ?

Hi
First, do not top-post[1].
In general you can find more information in /var/log/messages.
You "watch" with # (as root) tail -f /var/log/messages and from another window, try to mount.

I assume you have run something 'export -avr' since changing this file - or restarted the nfs server processes on the server?
You could try changing that line to:
/home/test *(rw)
then re-run 'export -avr' and try the mount again

Yeah ~ When I change that line in the /etc/exports on the guest system which installed the NFS server like that : /home/test *(rw)
then I run the "mount -t nfs 192.168.56.101:/home/test /media" on the host system , it will be ok ~
But when I change these message: /home/test 192.167.7.67(rw)
The result is not ok ~
So what is the problem with it ?

Hey I did appologise! We do use that feature of outlook internally, and if I reply to a html post, outlook will do that by default.
I already know the fix - To use my gmail account instead of my work email account for this mailing list.
Dan, You can force outlook to txt mode if you want, you needn't let it stick to its default. Look under Options/Format...

Perhaps you need to specify a netmask:
/home/test 192.167.7.67/255.255.255.0(rw)http://192.167.7.67/255.255.255.0%28rw%29
Appologies in advance for the html post. Bloody outlook.
Thanks for you reply ~
I tried that you suggested ,but the result is the same as I said . Perhaps it is the iptables problem, and I am doing with it now ~

Haha ~ I solved it just now. And the solution is the following :
1. Modify the /etc/exports file and add these: /home/test 192.168.56.0/24(rw) /home/test 192.168.7.0/24(rw)
2. In the host system , then run the following commands: /etc/init.d/portmap start mount -t nfs 192.158.56.101:/home/test /media
And the result is ok ~

The problem was, as I said in my previous post, that you use one subnet for you guest machine and another for your host machine.
I don't see how you could reach your guest machine (192.168.56.0/24) using your real interface, which is on 192.168.7.0/24 subnet, once you already put in your routes that 192.168.56.0/24 should be accessed using vnetbox0.
Pretty obvious.

Not very familiar with virtual box (I prefer vmware or kvm) but shouldn't you export to your vboxnet0 ip, which I presume is either 192.168.56.1 or 192.168.56.2?
Also, your iptables rule on the virtual machine is right now:
iptables -A INPUT -i eth0 tcp -s 192.168.7.67 --dport 111 -j ACCEPT
and I think it should be
iptables -A INPUT -i eth0 tcp -s 192.168.56.X --dport 111 -j ACCEPT
where 192.168.56.X is your vboxnet0 ip.
But again, I am not familiar with VirtualBox and it might have settings different than vmware or kvm.

You need to edit the ports in /etc/sysconfig/nfs to make them static before enabling IPTABLES. Once that is done you need to open not only those ports but also tcp:udp 111 and tcp:udp 2049.
