Question: After some automatic updates (or being hacked?) I have many things broken and a huge problem to resolve them since **I can't login as root anymore**.

* ssh admin: login success
* su root: permission denied (probably not the same password)

What I have tried:

* read log: but permission denied
* use 'synopass' and empty password: failed
* use synouser: permission denied
* change password of admin hoping it will update the root password: failed.
* check the root user in /etc/passwd: he is ok (with ash)
* restart all the server: failed

I have no idea what is going on. Any advice?

Answer: 
If your synology is in DSM6 and you're logged with a user part of administrator group, you can do :

**sudo -i**

enter your root/admin password

or even **sudo su -** (it works to)

now you're root tadaaa
If you're still with DSM Version 5, you might have logged in as admin instead of root. This makes a difference, even though root and admin share the same password.

To solve, do

```
ssh root@synology.local

```

with using the admin password.

This will log you in as root, with root access.
