[newjeans]

Environment: PVE 7.2,
LXC container: debian 11 (ip 192.168.0.182)
root ssh login in PVE node , successful.

issue: root ssh login in LXC container / debian 11 failed "permission denied (publickey,password)"
double checked, password for root is right.

try to fix by modify sshd_config
vim /etc/ssh/sshd_config
PermitRootLogin yes
and restart ssh service service sshd restart

root ssh login in failed again with "permission denied (publickey,password)"

By design for increased security SSH root login is configured disabled as the default.
