windos下用SSH连接linux主机

1.首先 linux 上要安装 yum install openssh-server 然后root cd ~ 然后 chkonfig –level 35 sshd （这个是保证linux 重启后自动开启sshd 服务）临时测试 直接service sshd restart

2.windos 下可以使用setupssh381-20040709 ssh 客户端 连接时

ssh 192.168.0.2 -l root 提示输入 要访问的linux主机root 密码

如果断开后再次连接可能会出现 known_hosts 错误 就把提示下文件删除就OK了

3.尽量不要修改linux 主机的语言编码环境。（有些乱码同学们喜欢修改，建议直接英文环境）


Linux 下同样会出现此问题，删除对应文件即可。
