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

浏览数：84 / 时间：2015年06月20日

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
