update:
if I did command:
sudo mount -o rw,vers=2 192.168.1.125:/mnt/sda1 /home/user/Desktop/NFS_shares/x10 -vv
returns

mount.nfs: timeout set for Wed Sep  2 13:12:20 2020
mount.nfs: trying text-based options 'vers=2,addr=192.168.1.125'

It's like nfs isn't start correctly, in fact from "netstat -a" I can see a process running only on port tcp 32778

Can you check is portmap running?

PS: I recommend you to install my new firmware

from rtd1295-openwrt18-porting.

davicom88 avatar davicom88 commented on June 14, 2024

yes I have just your last firmware

from rtd1295-openwrt18-porting.

davicom88 avatar davicom88 commented on June 14, 2024

portmap isn't install by default, I tried to install it but without any results, I re-try to install it. Could you suggest me if I need to configure something manually after installing portmap?

jjm2473 avatar jjm2473 commented on June 14, 2024

Oh, which version are you using?

We don't need portmap in new firmware.

I thought you are using old firmware, because this issue is in my old project.

portmap was replaced by rpcbind in new firmware

Wich command do you use to connect to Z9S on linux client?

from rtd1295-openwrt18-porting.

jjm2473 avatar jjm2473 commented on June 14, 2024

I never test NFS in linux client, but Mac OS client works fine.

I checked these commands on my Z9S:

root@Z9S:~# showmount -e localhost
Export list for localhost:
/mnt/sataa2 *
root@Z9S:~# showmount -e 127.0.0.1
Export list for 127.0.0.1:

following the guide on official openwrt site
https://openwrt.org/docs/guide-user/services/nas/nfs.server

I obtain error when I start nfs daemon, could this help you to check what my problem is?

And also to mount from another Linux client obtaining: permission denied

It seems like the kernel doesn't support nfsd.

There is some userspace NFS implements:

Is original x10 openwrt supports NFS server?

jjm2473 avatar jjm2473 commented on June 14, 2024

The kernel of x10 or other devices is not open source, so I can only use original kernel and it's kmods, can not add new kernel features.

If we want nfs server in x10, we can only port userspace NFS server to x10.

userspace means that it doesn't depends on kernel, it just a normal network application.
For example, samba in x10 is a userspace application, but it has a kernel version https://en.wikipedia.org/wiki/CIFSD

Download nfsd.ko.zip and unpack it,
copy nfsd.ko to x10's /tmp/ folder, then run insmod /tmp/nfsd.ko

Failed to find nfsd. Maybe it is a built in module ?

So I just copied file nfsd.ko into /tmp and the launched insmod /tmp/nfsd.ko in this way i get no error, but i don't know if it worked...

run ps |grep unfsd, you can see it running as nobody

it's running as root:

root@OpenWrt:~# ps |grep unfsd
  482 root      6140 S    /usr/sbin/unfsd -d

you can change /mnt/sda1 owner to nobody by command chown -R nobody:media_rw /mnt/sda1

from rtd1295-openwrt18-porting.

if you mount nfs without login, then it will changes to nobody

make sure the device not using by other service, this command will change ALL files' owner

it was mounted on samba, but strangely the the properties remains root

jjm2473 avatar jjm2473 commented on June 14, 2024

I use luci default option ro,sync,root_squash,all_squash,insecure,no_subtree_check, if the device is removable ( means that it not always exists ), use removable,ro,sync,root_squash,all_squash,insecure,no_subtree_check. The removable just for unfs3, not for kernel nfs server.

maybe you should add some options to mount samba

try mount -o uid=1023,gid=1023 when mount samba

user@server:~$ sudo mount -t nfs4 192.168.1.125:/mnt/sda1 /home/davicom/Desktop/NFS_shares/x10 -o vers=3
[sudo] password for user: 
mount.nfs4: access denied by server while mounting 192.168.1.125:/mnt/sda1

So I try this: I reboot, I remove auto-mount of samba from my pc and I get again chown -R nobody:media_rw /mnt/sda1

can you try a normal fat32 device first? not samba or ext4

yes, sure, just minute. yes nfs working with others devices

unfs3 support password https://github.com/unfs3/unfs3/blob/master/doc/passwords.txt

so, change NFS option to no_root_squash,rw,password=test,

and mount with mount -t nfs4 192.168.1.125:@password:test/mnt/sda1 /home/davicom/Desktop/NFS_shares/x10 -o vers=3,user=root
