## Create or change the NFS share
First of all edit your shared folder.
<kbd>Control Panel</kbd><kbd>Shared Folder</kbd><kbd>Edit</kbd>
<kbd>NFS Permissions</kbd><kbd>Create (or Edit)</kbd>.
![path to the settings as mentioned above](01-shared-folders-nas.png)
| Setting | Value |
| :--- | :--- |
| Hostname or IP | 192.168.10.100 (actual IP) |
| Privilege | Read/Write |
| Squash | Map all users to admin |
| Security | sys |
## Change the user and group ids in `/etc/exports`
Now login to the <abbr title="Network Attached Storage">NAS</abbr> with <abbr
title="Secure Shell">SSH</abbr> and open the file `/etc/exports` as the user
root.
The file should look similar to this one:
```
/volume1/video 192.168.10.100(rw,async,no_wdelay,crossmnt,insecure,all_squash,insecure_locks,sec=sys,anonuid=1026,anongid=100)
```
I have the following users on my NAS:
```
uid=1024(admin) gid=100(users) groups=100(users),101(administrators)
uid=1026(dominic) gid=100(users) groups=100(users),101(administrators),1000(nfs-dominic)
uid=1000(nfs-dominic) gid=1000(nfs-dominic) groups=1000(nfs-dominic)
```
Change the parts `anonuid=1026,anongid=100` to your needs.
I do have a personal folder that I change to `anonuid=1000,anongid=1000`
but I leave others (like video) that use `anonuid=1026,anongid=100`
(because I want the internal user on the NAS to use them too).
## Restart NFS Service on your NAS
Whenever you finished your changes to that file, save it and go back to
the control panel on the web interface.
<kbd>Control Panel</kbd><kbd>File Services</kbd><kbd>NFS</kbd>.
1. Disable NFS service, click <kbd>Apply</kbd>.
2. Enable NFS service, click <kbd>Apply</kbd>.
## Adopt your client
Edit your `fstab` file. Mine looks like this:
```
nas.lan:/volume1/video /home/dominic/_nas/video nfs noauto,users,nodev,async,soft,_netdev,x-systemd.device-timeout=1,x-systemd-idle-timeout=1min,x-systemd.mount-timeout=10,timeo=10,retry=3 0 0
```
