mount.nfs: access denied by server while mounting 192.168.65.1:/Users #10

Hi,

First of all let me thank you for such a brilliant solution, it works great!

But I have one problem with specifying custom mount points, I noticed the following errors in the moby VM:

mount.nfs: access denied by server while mounting 192.168.65.1:/Users
mount.nfs: access denied by server while mounting 192.168.65.1:/Users
mount: mounting 192.168.65.1:/Users on /Users failed: Permission denied

What might be the cause of this problem?

Many thanks.

Why are you using an IP?

@injectives after running d4m-nfs.sh, can you please the following commands and provide the output.

On you Mac:

showmount cat /etc/exports

On the Moby VM: df -h cat /etc/fstab

@pensiero I don't think he is explicitly using IPs, d4m-nfs get the default gateway IP, since it is about the only way that you can do an nfs mount from inside the Moby VM.

@if-kenn @pensiero Thank you for looking at this so quickly. Regarding IP - @if-kenn is correct, I haven't used it explicitly. Below is output of the commands:

/Users is removed from D4M Filesharing section obviously

I have multiple users on my Mac, it looks like changing the mounting point to specific user fixes the problem:

injectives$ cat etc/d4m-nfs-mounts.txt
/Users/injectives:/Users/injectives
