1, download installs the Xshell client, can choose the Personal/School Free edition when installs, this does not need to pay.
2, after the installation is complete, if you connect directly to the Ubuntu host will find that the connection is not, this is because the Ubuntu host does not open the SSH service, need to open openssh-server:
[Email protected]:~# sudo apt-get install Openssh-server
Use
[Email protected]:~# ps-e | grep ssh
If only ssh-agent indicates that it is not started, you need to
[Email protected]:~#/etc/init.d/ssh Start
If the sshd is displayed, it indicates that it has started successfully.
