Problem Statement
Can't connect to a Linux server(Debian Flavour) via SSH.
Error Message
Connection refused
Solution
There were unknown changes made in /etc/ssh/ssh_configfile. To fix this issue, we had installed OpenSSH server following below mentioned steps:
- Logged into VPS through console and fired following commands:
sudo apt-get purge openssh-server
mv /etc/ssh /etc/ssh_old
created new ssh directory in /etc
sudo apt-get install openssh-server​ - Try ssh after performing above steps. If you get "WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED", rename the known_hosts from .ssh/ in your local machine and try again.
