Answer 1

For what its worth I got the following error trying to ssh into my local machine, running Ubuntu 16.04 Xenial, from a vm.

 ssh: connect to host 192.168.144.18 port 22: Connection refused

It got immediately fixed with:

sudo apt-get install ssh

Take note, Before fix: 'which sshd' returned nothing and 'which ssh' returned

/usr/bin/ssh

And After the fix: 'which sshd' returned

/usr/sbin/sshd

Answer 2

What worked for me is:

sudo mkdir /var/run/sshd
sudo apt-get install --reinstall openssh-server

I tried all the above mentioned solutions but somehow this directory /var/run/sshd was still missing for me. I have Ubuntu 16.04.4 LTS. Hope my answer helps if someone has the same issue. ubuntu sshxenial

Answer 3

Try installing whole SSH package pack:

sudo apt-get install ssh

I had ssh command on my Ubuntu but got the error as you have. After full installation all was resolved.

Answer 4

I use a Mac, this worked for me:

Open System Preferences, then search for 'sharing'.

Choose Remote Login, make sure it is on and remember to add required users.

Answer 5

try sudo vi /etc/ssh/sshd_config

in first few lies you'll find

Package generated configuration file

See the sshd_config(5) manpage for details

What ports, IPs and protocols we listen for

Port xxxxx

change Port xxxxx to "Port 22" and exit vi by saving changes.

restart ssh sudo service ssh restart

Answer 6

if you are able to ping and not able to ssh, then it is a firewall. The firewall on 18.4 (not sure about other versions) in on by default and only allow port 8080.
