Why SSH connect refused after restore from my snapshot?

October 27, 2014 2.6k views

After creating a droplet from my snapshot, I tried to ssh my host remotely, but I received: ssh: connect to host port 22: Connection refused.
I can use web console on DO, and I typed vim /etc/ssh/sshd_config, it showed listen port 22.
I ran service ssh restart, it showed ssh start, but when I typed netstat -plutn , I can't find port22 was listening by ssh.
I can ping my server.
I want to ssh remotely in my computer, so what can I do ?
Please help me!

  • How did you access the shell if the ssh connection was refused?

  • Type service sshd status and look for Server listening on :: port xxxx ( mine was 3456 instead 22 ).

Alright, I've solve the problem by my own.
I typed /usr/sbin/sshd, (not /etc/init.d/ssh start, it seemed didn't work on me), and it showed that I had bad configurations ServerAliveInterval and ServerAliveCountMax in /etc/ssh/sshd_config. So I annotated two lines :

#ServerAliveInterval 30
#ServerAliveCountMax 5

And finally I run restart ssh, it displayed on terminal: ssh start/running , process 9794.
It didn't display process ... when I had the problem.
