SECURECRT the remote system refused the connection.

I encountered this problem when I was practicing remote login tool SECURECRT.

Ubuntu is installed by default openssh-client, so it is not installed here, if your system is not installed, then use the Apt-get installation can be.
Then confirm that the Sshserver is started:

Ps-e |grep SSH

If only ssh-agent that Ssh-server has not started, need to/etc/init.d/ssh start, if you see the sshd that shows that Ssh-server has been started.

Ssh-server configuration file is located in/Etc/ssh/sshd_config, where you can define the SSH service port, the default port is 22, you can define yourself as a different port number, such as 222. Then restart the SSH service:

Sudo/etc/init.d/ssh Resar

1. First install the server side of SSH on the server.

$ sudo aptitude install Openssh-server

2. Start Ssh-server.

$/etc/init.d/ssh Restart

3. Confirm that the Ssh-server is working properly.

$ NETSTAT-TLP

See above this line of output shows that Ssh-server is already running.

4. Log in to the server via SSH on the client.

SECURECRT the remote system refused the connection.
