The default SSH client installed in Ubuntu is openssh-client. If your system is not installed, use apt-get to install it. Then confirm whether the sshserver is started,
The command is as follows:
Ps-e | grep ssh
Or
Netstat-antp | grep 22
If only ssh-agent is available, the ssh-server has not been started. You need/etc/init. d/ssh start or service ssh start. If you see sshd, the ssh-server has been started.
The ssh-server configuration file is located in/etc/ssh/sshd_config. Here, you can define the SSH service port. The default port is 22. You can define other port numbers, such as 222. Then restart the SSH service:
Sudo/etc/init. d/ssh restart
Then you can use xshell4 to connect to the remote host.
