In recent Linux server distribs provided by dedicated server or VPN hosts, root login is often disabled, as well as password login. It doesn’t really improve security as long as you don’t use crappy passwords, and it’s one hell of an inconvenience. Restoring those is however easy (it’s also easy to find, but I prefer to keep my own copy here ^^):
sudo nano /etc/ssh/sshd_config
In it, set:
PasswordAuthentication yes
PermitRootLogin yes
Then restart the SSH daemon. For this 2 possible commands:
– I’ve always used sudo /etc/init.d/ssh restart
– I’ve also seen sudo service ssh restart
Also, don’t forget sudo passwd root to set the root password 😉
