虚拟机XP 连接 虚拟机 linux

来源:互联网 发布:电脑教室批量安装软件 编辑:程序博客网 时间:2024/06/07 09:35

使用软件: putty

虚拟机都使用   NAT  这样他们处于 一个网段中


linux 下  ifcondif  查看IP

XP    下   ipconfig  查看IP

linux 下查看 用户 密码等  cat /etc/passwd

问题:
  使用putty登录显示network error:Connection refused 或者显示network error:Connection timeout 

解决方法:
  1.vi /etc/ssh/sshd_config 将PermitRootLogin的注释取消,或者将no改为yes。(如果没有sshd_config文件说明linux上没有安装SSH,使用 yum -y  install ssh安装之后,sshd-config文件中PermitRootLogin选项默认的是yes,新安装的ssh不用操作下面两部)
  2.

  3.service iptables stop命令进入将防火墙关闭。

最后  登陆 用 root 账户登陆
