I am running an Ubuntu ssh server with login and ChallengeResponseAuthentication enabled. However, the following command outputs this and hangs until timing out:
ssh -vvv firstname.lastname@example.org 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 * debug2: ssh_connect: needpriv 0 debug1: Connecting to xxx.xx.xxx.xxx [xxx.xx.xxx.xxx] port 22.
When I try to ping the server address, the server responds. Except for the two changes mentioned above, the sshd_config file is the same as the default Ubuntu 14.04 file.
What steps should I take next to debug this?
sudo iptables -S prints the following:
-P INPUT ACCEPT -P FORWARD ACCEPT -P OUTPUT ACCEPT
The network should support SSH (another computer hooked into the network the same at this one (but running CentOS) can be ssh'd into no problem.
