I can login to SSH with web interface but it does not work from my Mac when I type ssh root@IP I have not setup SSH Keys. I wish to login with password. Looks like I am missing something obvious. I had used other competing cloud services (not sure if I can mention it here) and I always could login. Thanks

What's the output of ssh -vvv root@IP?

    I get this:

    OpenSSH_6.2p2, OSSLShim 0.9.8r 8 Dec 2011
debug1: Reading configuration data /etc/ssh_config
debug1: /etc/ssh_config line 20: Applying options for *

ssh: connect to host 104.236.191.115 port 22: Operation timed out

    I've added my local machine's public ssh to digital ocean. I'm also using Cloud66.

    Ah, yeah so I just had to add a rule in the firewall settings for Cloud66

    Better yet, I can open a temporary connection through Cloud66 to increase security.

Hmm. Log in to your droplet through the Web Console and run the following command:

cat /etc/ssh/sshd_config | curl -F 'sprunge=

You have to uncomment (remove the #) the following line and restart ssh:

#PasswordAuthentication yes

save the file and restart sshd: "service ssh restart"

You should now be able to login using your password.

Did you edit /etc/ssh/sshd_config on your droplet? The file you pasted is ssh_config.
Reply
artem.babenko July 2, 2013
Yes. I edited file in droplet.
sprunged it
http://sprunge.us/AEcU

Restarted ssh
It does not helped

Then I did reboot

The file you sprunged is /etc/ssh/ssh_config, make sure you're editing /etc/ssh/sshd_config

artem.babenko July 2, 2013
My bad but nothing changed after I edited sshd_config

I did ssh restart and then I also did reboot

Here is sshd_config

http://sprunge.us/gJEF

I have not setup any ssh key with digital ocean

I just created 1 droplet

Please run the following commands:

rm /etc/ssh/ssh_host*
dpkg-reconfigure openssh-server

Restart ssh and you should be able to login.

I faced the same issue today. Tried all the steps mentioned here, but no success. Eventually, did a power cycle, and was able to login. The only change I had made to my droplet before this problem occurred, was adding a crontab entry to start my service at reboot. Is there a better way known to solve this SSH issue?
