Linux 入门 1 (vm虚拟机安装openSUSE 11,SecureCRT远程连接)

Linux版本:

  openSUSE-11.0-GNOME-LiveCD-i386.torrent ,(680M)下载地址:http://ftp5.gwdg.de/pub/opensuse/discontinued/distribution/11.0/iso/torrent/

  安装都是默认的,设的硬盘大小是8G,内存1G,网络连接时桥接,分区挂载都是快速安装默认的,自己没修改。


  安装好后,ifconfig查看suse的ip为192.168.1.103,而物理机(笔记本)是192.168.1.100,从物理机可以ping通suse,而suse端ping -c4 192.168.1.100无法ping通物理机。。。

  解决方法:将物理机的防火墙关闭即可。

 

secureCRT连接suse提示“未连接”的问题

  1、没有安装openssh(ubuntu没有安装

  2、没有启动sshd服务(可以netstat -antp 命令查看

  3、防火墙没打开

 

  用netstat命令查看,发现sshd服务已经是启动的状态了,所以只能是防火墙没打开的缘故

  

 

  打开防火墙的方法参考:http://blog.csdn.net/aaronychen/article/details/2802199 

  打开这个文件:/etc/sysconfig/SuSEfirewall2,该文件内部的一部分如下:

  

  使用命令:rcSuSEfirewall2 restart    //重启防火墙,以使配置生效

 

  

 


开机默认以文件界面启动

  修改 /etc/inittab 文件里的默认启动级别

 将上面红色字体部分里的 id:5 改为 id:3 保存,重启电脑即可。
