Ssh: connecttohostxxx. xxx. xxx. xxxport22: Connectionrefused (taking Ubuntu12.04 as an example)

Source: Internet
Author: User

When using ssh, the following error occurs: connect to host xxx. xxx port 22: Connection refused.

The cause of this error is that the ssh-server is not started or not installed (Ubuntu12.04 only openssh-client is installed by default, and openssh-server is not installed ).

1. Check whether openssh-sever is enabled.

Run the following command:

Ps-e | grep sshd
If no sshd process exists, run the following command:
Sudo/etc/init. d/ssh start
2. Install openss-server

If ssh does not exist, openssh-server is not installed. Run the following command to install openssh-server.

Sudo apt-get install openssh-server
