[SOLVED]nfs server on rtd1295

[davicom88]

as previously said privately, in my opinion you did a great job: but I can't get NFS server working, any help should be really appreciated:

Ip of my nfs server "X10 rtd1295" is 192.168.1.125
i set my export on Luci:
/mnt/sda1 192.168.1.28/24(rw,sync,root_squash,all_squash,insecure,no_subtree_check)

then I try to mount it from my linux host 192.168.1.28

sudo mount -t nfs 192.168.1.125:/mnt/sda1 /home/user/Desktop/NFS_shares/x10
[sudo] password for user: 
**mount.nfs: requested NFS version or transport protocol is not supported**

As you suggested me, I put exportfs -a on cli on openwrt but I get nothing return

[davicom88]

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'
mount.nfs: prog 100003, trying vers=2, prot=6
mount.nfs: portmap query retrying: RPC: Program not registered
mount.nfs: prog 100003, trying vers=2, prot=17
mount.nfs: portmap query failed: RPC: Program not registered
mount.nfs: requested NFS version or transport protocol is not supported

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

[davicom88]

yes I have just your last firmware

[davicom88]

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]

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.

[jjm2473]

portmap was replaced by rpcbind in new firmware

Ah ok, but the problem remain:

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

[jjm2473]

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

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?

I didnt' mean you have to help me. What you have done it's yet amazing. Sorry for my little english anyway... :)

[davicom88]

In meantime I also tried to mount different path: /tmp with same result
And also to mount from another Linux client obtaining: permission denied

[jjm2473]

can you run lsmod in Openwrt?
