windows下SSH客户端远程访问Linux出现错误

在windows下ping远程linux服务器可以数据包接收正常说明不是防火墙的原因;

The host '192.168.124.1' 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

原因是没有启动sshd服务

启动服务就可以正常访问。
service sshd start

sshd服务配置文件
/etc/ssh/sshd_config

Port
Protocol
ListenAddress 10.226.70.30        //监听地址
PermitRootLogin yes               //允许root登录
