root is not getting admin password.

Post by penright »

The subject basically says the issue. I am trying to clean up an owncloud and when I try to delete the owncloud folder, I do not have permission. Also, I can not sudo.

I have read a lot about "root access" from ssh. I see the root password should be the same as admin, is that correct? So for ssh should I be using root and the admin password? If so then when I try to ssh with and log in with root and admin password is like the password is wrong.

So, as I said, what should I do to get root access so I can remove the owncloud directory, so I can do a fresh install?

First log in with the administrator, and then sudo -i to switch the root user, the password is the administrator password.

I'm experiencing the same issue after updating to 4.2.13. Worse yet, both su and sudo seem to have their permissions set incorrectly:

(admin@filer01) Password:
Welcome to Tnas!
[admin@filer01 ~]$ ls -l /bin/su
lrwxrwxrwx 1 root root 7 Nov 25 2019 /bin/su -> busybox
[admin@filer01 ~]$ su -
su: must be suid to work properly
[admin@filer01 ~]$ sudo -i
sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
[admin@filer01 ~]$ ls -l /usr/bin/sudo
-rwxr-xr-x 1 root root 139248 Jun 17 13:59 /usr/bin/sudo

sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
The following steps are the solution:
1. Turn off the device and turn it on without any hard disks
and TNAS PC found the device.
2. Log in as root, password admin(IP+9222)
3. After logging in to the background, insert all hard disks and enter the following command
ls /dev/sd*
4. After seeing the hard disk information, execute the command
/etc/tos/scripts/mntcore
chmod 4755 /mnt/core/usr/bin/sudo
5. Then enter reboot.
