The host '192.168.174.130' is unreachable.
the host may be down,or there may be a problem with the network connection.
Sometimes such problems can also be caused by a misconfigured firewall。
在SSH Secure Shell Client登陆的时候,出现了上述的提示,搞了好久,但是没发现错误的地方。网络是通的,即Linux和Windows可以相互的ping 。防火墙也关闭了。
后来在centos下输入service sshd status的时候,发现openssh-daemon is stopped。也就是没有启动sshd服务。
启动服务就可以正常访问了:service sshd start。此时输入service sshd status就会提示:openssh-daemon(pid 1844) is running.此时即可正常访问了。
