Unable to use sftp with root account
Hello, I am used to connect to my LAN server using sftp (with tectia client), logging in as "root".
My server is a Debian testing updated day by day.
Since 2 or 3 days I am unable to connecto to the server as "root".
If I try to connect with another account I get in; seems that some software are blocking me if I try root access.
I looked in /etc/ssh/sshd_config and pam config but nothing's wrong. I also tried to restore old configuration but nothing.
Any idea ?
