解决方案:
1.安装openssh-server
Ubuntu缺省安装了openssh-client,所以在这里就不安装了,如果你的系统没有安装的话,再用sudo apt-get install openssh-server安装上即可。
1.1输入命令:sudo apt-get install openssh-server
1.2确认openssh-server是否启动了:
ps -e |grep ssh
正常情况下结果为:
1584 ? 00:00:00 ssh-agent
2299 ? 00:00:00 sshd
1.3如果只有ssh-agent,则openssh-server还没有启动,需要/etc/init.d/ssh start,如果看到sshd那说明openssh-server已经启动了。
2.ssh-server配置文件位于/etc/ssh/sshd_config,在这里可以定义SSH的服务端口,默认端口是22,你可以自己定义成其他端口号,如222。然后重启SSH服务:
sudo /etc/init.d/ssh restart
