FreeBSD and NFS

abosio · Jul 23, 2008

Can anyone help me figure out the right settings for the VM networking configuration and FreeBSD exports so that I can mount NFS no matter where I am?

I am running Parallels Desktop for Mac on Leopard on a Macbook Pro.

When I am connected at the office to the LAN, it works with VM set to Shared networking in the following scenario.

Mac ifconfig:

Code:

en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
	inet6 fe80::21e:c2ff:fec3:c773%en1 prefixlen 64 scopeid 0x5

	lladdr 00:1f:f3:ff:fe:26:1b:1c

	supported media: autoselect <full-duplex>

	inet 10.211.55.2 netmask 0xffffff00 broadcast 10.211.55.255
	ether 00:1c:42:00:00:01 
	media: autoselect status: active
	supported media: autoselect
en3: flags=8963<UP,BROADCAST,SMART,RUNNING,PROMISC,SIMPLEX,MULTICAST> mtu 1500
	inet6 fe80::21c:42ff:fe00:0%en3 prefixlen 64 scopeid 0x8 
	inet 10.37.129.2 netmask 0xffffff00 broadcast 10.37.129.255
	ether 00:1c:42:00:00:00 
	media: autoselect status: active
	supported media: autoselect

FreeBSD ifconfig:

Code:

ed0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500
	ether 00:1c:42:e6:45:1c 
	inet 10.211.55.6 netmask 0xffffff00 broadcast 10.211.55.255
	media: Ethernet autoselect (10baseT/UTP)
lo0: flags=8049<UP,LOOPBACK,RUNNING,MULTICAST> metric 0 mtu 16384
	inet6 fe80::1%lo0 prefixlen 64 scopeid 0x2
	inet6 ::1 prefixlen 128
	inet 127.0.0.1 netmask 0xff000000

FreeBSD /etc/exports:

Code:

/usr/home/abosio -maproot=abosio 10.211.55.2

Then I can connect with Command-K and Server Address: nfs://10.211.55.6/usr/home/abosio

When I am at home, I only seem to be able to get it to work if I switch to Host-only networking, at which point my VM can't see the internet, which is a problem. I believe the only difference at home is that I am connected to an Airport and my Mac IP becomes 192.168.1.x.

I have tried lots of different ways with Shared and Bridged Ethernet networking on the VM with no success.

If anyone has any ideas about how to make this work, that would be great.

John@Parallels · Jul 23, 2008

Is adapter set to default? in Configuration Editor -Network Adapter

abosio · Jul 23, 2008

In the "working scenario" (at the office) it is on Shared, so no.

In the "not working scenario" (at home) yes, I had it on Default Adapter, not en0: Ethernet Adapter or en1: Airport/Wireless Adapter.

Should I change it to one of those?

John@Parallels · Jul 23, 2008

Usually default should work always, only problem is for internet connection from VM, during location change , if you do not stop VM, when going home (I mean you just pause it)

abosio · Jul 23, 2008

This is always starting from a stopped state, not paused.

So I need to use Bridged with Default and then connect with the 10.211.55.x addresses? (instead of shared?)

I think I have tried that, but can go through it again.

John@Parallels · Jul 24, 2008

No, I meant try to use Bridged Ethernet and assign IP from the same range as your Lan
Another matter I can guess can be problem with Parallels Nat interface,
Try to check ifconfig -a when at work and when at home from Mac OS side
if you see 169.254.xxx this is poblem

abosio · Jul 24, 2008

When I switch to Bridged, it does automatically get assigned an IP from my LAN but I cannot mount NFS with that address at home (or at the office).

I can't understand why Shared doesn't work at home. None of the addresses involved in that setup get changed.

To recap at this point:
- NFS mount works with Shared at office but not at home.
- NFS mount doesn't work with Bridged at all.
- NFS mount works at office and at home with Host-Only, but I need internet on the VM.

I keep changing /etc/exports to reflect my current Mac IP depending on which network setting I am using for the VM.

John@Parallels · Jul 26, 2008

Try to restart Mac when you come home, and try to access VM, let me know the results

abosio · Jul 27, 2008

When I bring the mac home, I am already always starting from a powered-off state. All results above are from that basis.

John@Parallels · Jul 27, 2008

Do you have proxy configured at work,
if yes, are there several locations in System Preferences -Network?

abosio · Jul 27, 2008

No proxy at work. Only one location - "Automatic" - in System Preferences-Network.

p.s. I really appreciate your response (and help) - and totally recognize its ridiculous-ness for a Sunday evening.

John@Parallels · Jul 27, 2008

It looks that you have problem similar to this http://discussions.apple.com/thread.jspa?threadID=1143161
en0 and en1 are changing,
I believe this is causing problem.
Try to disable built-in Ethernet at home and check what is going on

abosio · Jul 27, 2008

I made Ethernet inactive in System Preferences.

Still can't mount on Shared or Bridged.

John@Parallels · Jul 27, 2008

There is something with interfaces itself,

it is from work, but you say in office you are working in LAN, but this is showing AirPort, if you check work configuration you provided it shows that you are connecting by AirPort not Lan

abosio · Jul 28, 2008

Yes, sorry. I have been using the Airport at home and at work. I just meant that at work I am connecting to my company's network. (via secured wifi)

en0 and en1 are changing,
I believe this is causing problem.

Where in my ifconfig are you see them changing? I'm am not seeing the connection with the link to Apple Discussion Forums.

John@Parallels · Jul 29, 2008

No, it is ok, now, as you confirmed that in both places you are using AirPort,Situation is getting interesting
Check can you ssh from Mac to FreeBSD at home, and is there any firewall on Mac oS?

abosio · Jul 29, 2008

I'll try ssh when I get home tonight, but I know I can ping between them.

According to System Preferences -> Security -> Firewall, Mac is currently set to "Allow all incoming connections."

John@Parallels · Jul 29, 2008

Ok, great , One more point to clarify, please shutdown OS to, not suspend.
So, shutdown VM, and Mac OS and at home just turn both on

abosio · Jul 29, 2008

SSH from Mac to FreeBSD VM:

- Shared: yes
- Bridged: yes (Default adapter, only en1:Airport in drop-down)
- Host-only: yes

John@Parallels · Jul 29, 2008

It should work in this case, maybe iptables? try to disable iptables in FreeBSd
