ssh: connect to host 119.78.226.156 port 22: Connection refused

回答: 报错信息"ssh: connect to host 119.78.226.156 port 22: Connection refused" 表示连接到主机119.78.226.156的22端口被拒绝。通常情况下，SSH服务默认监听22端口。可能的原因是SSH服务未启动或者被配置为监听了其他端口。如果你是系统管理员，可以检查SSH服务器的配置文件"/etc/ssh/sshd_config"，查找"Port"关键字，确认正确的端口号。如果你不是管理员，请联系管理员咨询正确的端口号。此外，还可以检查主机的防火墙设置，确保允许SSH连接通过。如果以上方法都没有解决问题，那可能是另外的错误引起的，比如网络连接问题或者服务不可用。<span class="em">1</span><span class="em">2</span><span class="em">3</span>
