Hi Thomas,

Thanks for your quick reply!

Here are the details

# ls -la /etc/shadow
-rw-------??? 1 1000???? 1000?????????? 190 Aug? 7? 2020 /etc/shadow

# cat /etc/shadow
root:$5$D1pz/P1l$JCZhyjzCCqmXbnPx7g/mBtNtSSKkMqgctsmV/zBmlR2:::::::
daemon:*:::::::
bin:*:::::::
sys:*:::::::
sync:*:::::::
mail:*:::::::
www-data:*:::::::
operator:*:::::::
nobody:*:::::::

# passwd
Changing password for root
New password:
Bad password: too short
Retype password:
passwd: password for root changed by root

# cat /etc/shadow
root:$1$SYGd3a37$u2RV/VOsLPqWznY4GR1jU.:13514::::::
daemon:*:::::::
bin:*:::::::
sys:*:::::::
sync:*:::::::
mail:*:::::::
www-data:*:::::::
operator:*:::::::
nobody:*:::::::

# ls -la /etc/shadow
-rw-------??? 1 1000???? 1000?????????? 174 Aug? 7? 2020 /etc/shadow

I set the password the "root" (both in "menuconfig" and then through the
"passwd" command). Only after this command can I login through ssh.

Cheers,

Michael.
