Linux系统下安装配置Dynamips的方法

首先先下载
　
　　http://www.ipflow.utc.fr/dynamips/dynamips-0.2.5-x86.bin
　
　　http://nchc.dl.sourceforge.net/sourceforge/dyna-gen/dynagen-0.6.0.tar.gz
　
　　http://www.tcpdump.org/release/libpcap-0.9.5.tar.gz 这3个文件到/root下
　
　　1.安装libpcap
　
　　tar -zxvf libpcap-0.9.5.tar.gz
　
　　。/configure
　
　　make
　
　　make install
　
　　2.复制/root/dynamips-0.2.5-x86.bin到/usr/local/bin/下
　
　　cp dynamips-0.2.5-x86.bin /usr/local/bin
　
　　ln -s dynamips-0.2.5-x86.bin dynamips
　
　　3.解压dynagen-0.6.0.tar.gz
　
　　tar -zxvf dynagen-0.6.0.tar.gz
　
　　cd /usr/local/bin/
　
　　ln -s /root/dynagen-0.6.0/dynagen dynagen
　
　　好了，这样就可以找个net文件来启动dynamips了，建议建个dynamips的文件夹，把dynamips，IOS，net文件都放进去
　
　　启动dynamips：
　
　　nice dynamips -H 7200
　
　　启动控制台：
　
　　dynagen /root/dynamips/xxx.net
　
　　进入控制台，跟windos下就一模一样了。
　
　　获得idle_pc
　
　　dynamips -P 3600 -t 3620 /root/dynamips/xxx.bin（这里是3620的IOS文件）。
　
　　等到进入到route>命令行后，按"ctrl+]"松开后按i，就可以获得很多idle_pc号，复制count最大的那个到net文件里就OK了。
　
　　至于网卡参数，把net文件中的NIO_gen_eth：xxx改成NIO_linux_eth：eth0就行了。
　
　　在控制台下启动路由器后，新开启一个终端，然后telnet 127.0.0.1 3001（这里是R1的端口号）就可以进入路由器。
