3.EVE-NG导入Dynamips和IOL（转）
Dynamips导入过程一、查看EVE的地址，并用SFTP工具连接（本文以SecureFX为例）http://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602561588.pnghttp://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602561496.png二、上传镜像文件到相应目录镜像保存目录：/opt/unetlab/addons —/dynamipsDynamips镜像保存目录 —/iol IOL镜像保存目录（运行IOU的镜像） —/qemu QEMU镜像（运行ASAv、ISE、F5等等镜像）将dynamips镜像上传到/opt/unetlab/addons/dynamips目录下http://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602561684.png三、修正镜像权限用SSH登录到EVE，运行如下命令/opt/unetlab/wrappers/unl_wrapper -a fixpermissionshttp://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602561714.png
注意：有可能您的机器跑Dynamips后CPU利用率非常高，计算idlepc后利用率会降到最低，此处就先不介绍idlepc计算方法了，今后如各位有需要再补充！个人觉得，有了vios和iol后，dynamips就没必要使用了！如果各位有兴趣，进QQ群：593920308（EmulatedLab）获取idle值计算方法！
IOL导入过程一、上传镜像到相应目录
与IOL有关的文件包含IOL的镜像iourc文件（IOL的license文件）CiscoIOUKeygen.py（python脚本，用于生成license）
将如上文件全部上传到/opt/unetlab/addons/iol/bin目录下http://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602561893.png二、生成并编写license第一种方法：命令自动生成确保CiscoIOUKeygen.py已经上传后，执行命令cd /opt/unetlab/addons/iol/bin/
python CiscoIOUKeygen.py | grep -A 1 ‘license’ > iourc
生成license代码http://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602562540.jpg第二种方法：手动修改生成license代码root@eve-ng:~#cd /opt/unetlab/addons/iol/bin
root@eve-ng:/opt/unetlab/addons/iol/bin# ls

Cisco IOU License Generator – Kal 2011, python port of 2006 C version
Modified to work with python3 by c_d 2014
hostid=007f0101, hostname=eve-ng, ioukey=7f0343
Add the following text to ~/.iourc:
eve-ng = 972f30267ef51616;
You can disable the phone home feature with something like:
echo ‘127.0.0.127 xml.cisco.com’ >> /etc/hosts
root@eve-ng:/opt/unetlab/addons/iol/bin#红色字体即IOL的license，这段代码随着EVE-NG的hostname变动，hostname不同，计算的结果也不同。
编写license文件安装vim（确保EVE联网）apt-get updateapt-get install vimroot@eve-ng:/opt/unetlab/addons/iol/bin# vim iourchttp://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602561918.png把原来的删除掉，重新粘贴新的license代码:wq! 保存退出三、修正镜像权限运行如下命令/opt/unetlab/wrappers/unl_wrapper -a fixpermissions运行镜像测试不会的朋友请看历史文章，不做详细介绍用web界面登录并添加设备，这时候能看到Cisco IOS与Cisco IOL几项已经被点亮。http://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602562077.png选择一个Cisco IOS 7206VXR和一个Cisco IOL做测试http://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602562124.pnghttp://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602562248.pnghttp://www.emulatedlab.com/wp-content/uploads/2017/06/2017072602562349.pnghttp://www.emulatedlab.com/wp-content/uploads/2017/06/201707260256248.png
已经通了！此处有必要说一下，以前用GNS3时Dynamips与IOL的设备中间直连会报错，中间必须增加一个GNS3自带的二层交换机才能正常通信。而EVE-NG不需要~~~

那么请问，哪里才能下载到CiscoIOUKeygen.py 呢？ 受教了，感谢感谢。 andyzhang209 发表于 2018-7-9 11:37

存到記事本，另存成CiscoIOUKeyGen.py檔 我导入镜像之后只点亮了Cisco IOL一项，点开Cisco IOL里面的image有好多，全在里面了，这是怎么回事？ dddd咕咕咕咕咕咕过。
