Question

Console Login Works, SSH Login Doesn't

When I click console, I am prompted for a login. I use “root” and then enter my password. That works fine.

I use putty to SSH in, I am prompted for a login. I use “root” and then enter my password (as prompted), but it doesn’t accept the login credentials.

Hi @usedearplugs

Have you modified security settings for SSH or root at some point?

Login on console, then run tail -f /var/log/auth.log. Now login over SSH and have it fail. What do you see in the console? Also have a look with tail -50 /var/log/syslog

You can take screenshots of the console and upload to imgur.com and post link here.

If you’re able to log in to console, but not via SSH, ufw is probably active and you’ve been blocked.

If you log in to console, run ufw status and see if ufw is running. If it is, you can disable using:

ufw disable

Once disabled, try to login via SSH. If you’re able to login once again, I’d simply reset ufw and add your policies back.

ufw reset

ufw default deny incoming

ufw default allow outgoing

Allow SSH:

ufw allow 22/tcp

If you need HTTP/HTTPS (Ports 80 and 443):

ufw allow 80/tcp

ufw allow 443/tcp

Once you’ve setup your firewall rules as above, re-enable ufw:

ufw enable
