No Sudo Rights on BBB Client Using NFS Server

Embedded Linux Discussions
1

Hi there.

I have a BBB that successfully boots from my Ubuntu desktop running the NFS service. The problem is I can, while in the BBB via SSH, kick around a little bit. I can create files and run Python3 scripts - which is all I really need. The problem is I can’t use any privileged commands, because sudo won’t work . I want to embedded this BBB into a box, and I don’t want to open it up every time to reboot it if I place a new kernel or different rootfs on the easily accessible desktop.

I was wondering if there is a way to have the rootfs be temporally owned by the BBB so that I can use “sudo reboot” to have the new kernel booted, or if there is another way to reboot the BBB to use the new kernel/rootfs on the desktop?

Kind regards,
Jack

Hi @Jack_Nightengale, this smells like you are missing “no_root_squash” in your nfs configuration.

Please confirm your NFS settings from /etc/exports…

Regards,

My exports file is configured as follow:

/var/rootfs 192.168.1.0/24(rw,sync,no_root_squash,no_subtree_check,anonuid=1000,anongid=1000)

My hope was that when I added the anonuid=1000 and anongid=1000 I would map the BBB Debian id to my main user on the desktop (id=1000).

Kind regards,
Jack

I think it’s also worth mentioning that I don’t have root on the BBB and that the rootfs is owned by root in the desktop.

Hi @Jack_Nightengale,

The default user was set to 1000, so you shouldn’t need to change anonuid/anongid. When i test NFS, I just use:

/opt/buster/ *(rw,sync,no_subtree_check,no_root_squash)

Correct, root on ubuntu is disabled… (it’s an ubuntu thing…)

Regards,

6

@RobertCNelson, I’ll quickly check if I place the rootfs under the opt directory, and edit the nfs configuartion if anything changes.

7

@Jack_Nightengale i wouldn’t worry about the directory, but i’d rip out those anonuid=1000,anongid=1000 settings and try again…

Regards,

@RobertCNelson I still can’t use sudo. Here is the output:

@Jack_Nightengale, i just retested my directions… I’m not sure what’s blocking “sudo” on your system, it might be how you copied the file system from the Beagle…

@RobertCNelson Thank you for the detailed response. I checked all my services, my tftpd-hpa is configured as above, and the command

debian@beaglebone:~$ mount | grep nfs

gives me the same output as your, just my IPs differs.

192.168.1.254:/var/rootfs on / type nfs (rw,relatime,vers=3,rsize=4096,wsize=4096,namlen=255,hard,nolock,proto=udp,timeo=11,retrans=3,sec=sys,mountaddr=192.168.1.254,mountvers=3,mountproto=udp,local_lock=all,addr=192.168.1.254)

It might be files ownership on the desktop that is blocking it. Here is the file ownership on the BBB:

I also created a file on the desktop using sudo to see what would happen, and got this:

-rw-r–r-- 1 root root 1178 Feb 17 2020 list

Is there another way to reboot the board? And how did you copy the rootfs on your system?

Kind regards,
Jack

11

Also I get debian with whoami, and sudo whoami get the error sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set.

12

I’ve tried everything I can think of. I’ve changed ownerships, I tried all of the NFS squash options. I’ve placed the NFS in a home directory, root directory and subroot directory.

13

@Jack_Nightengale, your root file system on your x86 doesn’t have the correct permissions…

Did you run rsync as root when you copied it over?

Regards,

14

No, I did not. I just copied the image off of the SD Card into a folder. Should I run the nfs-rsync.sh from the rootfs directory on the desktop or when I’ve SSH’d into the BBB?

I’ve also changed the ownership of the rootfs to root on the desktop.

Regards.

15

@RobertCNelson Do I just copy the rfs from the SD card into the directory, as root, and then run the rsync script or the rsync command?

16

Hi @Jack_Nightengale, i recommend user ‘boot’ off the microSD and then transfer the data from the BBB to you nfs server via rsync. So using your previous post’s i would:

Boot BeagleBone Black off microSD

Create a temporary nfs mount point:

sudo mkdir /tmp/rootfs/

Mount your nfs server (192.168.1.254 based on your posts)

sudo mount -t nfs -o rw,nfsvers=3,rsize=8192,wsize=8192 192.168.1.254:/var/rootfs/ /tmp/rootfs/"

Then transfer your BeagleBone Black’s rootfs via rsync: (this has the --delete flag, so it’ll clear out any difference in your NFS’s directory…)

sudo rsync -aAx --human-readable --info=name0,progress2 --delete /* /tmp/rootfs/ --exclude={/dev/*,/proc/*,/sys/*,/tmp/*,/run/*,/mnt/*,/media/*,/lost+found}

Regards,

17

@RobertCNelson Good day, sorry it’s been almost a month since you gave me an answer. Thank you so much for your response. I just got my hardware back from storage today. Just ran the commands (after battling to set up everything again). Will let you know how it goes.

Again, my apologies and thanks,
Jack.

18

@RobertCNelson The rsync seems to have worked, thank you.

The ethernet interface seems to go down, just before the BBB tries to connect to the nfs server. See the 3rd and 2nd last lines out the output.

Also,

<ethaddr> not set. Validating first E-fuse MAC

Do I just need to configure the ethernet interfaces?

Also I found this:

[ 0.000000] Kernel command line: console=ttyO0,115200n8 root=/dev/nfs rw rootfstype=ext4 rootwait fixrtc nfsroot=192.168.1.254:/var/rootfs,vers=3 ip=192.168.1.10:192.168.1.254:192.168.1.1:255.255.255.0::eth0:off

Anyway I can fix this? I’ve tried the uEnv.txt file, but correct me if I’m wrong but I think U-Boot gives the boot arguments to the kernel. I honestly have no idea how to fix this.

Kind regards.
