2、导入gns3 vm（分vmware esxi和vmware workstation pro版本）

 

vmware esxi版本：

部署中…

开机：

回车配置：

问题：没有开启kvm。

将虚拟机关机，开启esxi的虚拟化透传。

关机中。。。

再重新开机。。。

回车再重启，kvm已经启用。

 

配置固定ip地址（根据实际情况修改）：

auto eth0

# Comment this line to disable DHCP
#iface eth0 inet dhcp    //注释这一行
# Uncomment this lines if you want to manually configure network
# It's not recommended if you can avoid it.
#
iface eth0 inet static       //取消注释
        address 192.168.0.50
        netmask 255.255.255.0
        gateway 192.168.0.1
        dns-nameservers 192.168.0.1       //改为114.114.114.114等dns

 

Ctrl+x

输入y

回车

检查：

                                                  esxi版本完。

 

------------------------------------------------------------------

vmware workstation pro版本：

 

                        vmware workstation pro安装完毕。

选择一个目录：

开启vt-x:重要

修改ip：

# This file describes the network interfaces available on your system
# and how to activate them. For more infORMation, see interfaces(5).

# Warning this file will be erased by each
# GNS3 VM update; if you want to customize it
# change the following var to 1 but DO NOT
# remove the leading #.
#
# MANUAL=0

# Host only interface
auto eth0

# Comment this line to disable DHCP
#iface eth0 inet dhcp        //关闭dhcp
# Uncomment this lines if you want to manually configure network
# It's not recommended if you can avoid it.
#
iface eth0 inet static              //配置静态ip地址
        address 192.168.92.100
        netmask 255.255.255.0
        gateway 192.168.92.1
        dns-nameservers 114.114.114.114

 

地址配置完毕会自动重启！

 

连接gns3 vm：

重启gns3 client。

上传镜像：

 

 

                                                            -----vmware workstation pro版本完

 

3、windows 安装GNS3-2.1.21-all-in-one.exe

需要Update for Universal C Runtime in Windows：根据系统下载。

https://support.microsoft.com/en-us/help/2×××26/update-for-universal-c-runtime-in-windows#!en-us%2Fhelp%2F2×××26%2Fupdate-for-universal-c-runtime-in-windows

 

windows 7 x64下载：

https://download.microsoft.com/download/1/1/5/11565A9A-EA09-4F0A-A57E-520D5D138140/Windows6.1-KB2×××26-x64.msu

 

安装wireshark，狂点下一步。。。

正式安装gns3-ui：

安装完毕。

---------------------------------------------------------------

 

4、基本配置：Edit—>Preferences

关联scrt：

关联vnc：

项目路径：

应该是禁止任何中文字符。

 

安装scrt：狂点下一步。。。

破解方法：自行搜索。

 

gns3 client连接gns3 vm：

判断连接成功：

环境准备完--------------------------------完

 

5、上传路由器IOU的镜像：

 

镜像导入成功，但是没有license，还不能用。

下一步，ssh登录至gns3 vm，生成license：

root@gns3vm:~# python3 CiscoIOUKeygen.py
*********************************************************************
Cisco IOU License Generator - Kal 2011, python port of 2006 C version
Modified to work with Python3 by c_d 2014
hostid=00000000, hostname=gns3vm, ioukey=25e

Add the following text to ~/.iourc:
[license]
gns3vm = 73635fd3b0a13ad0;                       //生成的license

You can disable the phone home feature with something like:
echo '127.0.0.127 xml.cisco.com' >> /etc/hosts

 

将软件粘贴至gns3客户端软件中：

拖出两台路由器测试：

------------------------------------------全文完。

 

附CiscoIOUKeygen.py源码

#! /usr/bin/python
print("*********************************************************************")
print("Cisco IOU License Generator - Kal 2011, python port of 2006 C version")
print("Modified to work with python3 by c_d 2014")
import os
import Socket
import hashlib
import struct

# get the host id and host name to calculate the hosTKEy
hostid=os.popen("hostid").read().strip()
hostname = socket.gethostname()
ioukey=int(hostid,16)
for x in hostname:
ioukey = ioukey + ord(x)
print("hostid=" + hostid +", hostname="+ hostname + ", ioukey=" + hex(ioukey)[2:])

# create the license using md5sum
iouPad1 = b'\x4B\x58\x21\x81\x56\x7B\x0D\xF3\x21\x43\x9B\x7E\xAC\x1D\xE6\x8A'
iouPad2 = b'\x80' + 39*b'\0'
md5input=iouPad1 + iouPad2 + struct.pack('!i', ioukey) + iouPad1
iouLicense=hashlib.md5(md5input).hexdigest()[:16]

print("\nAdd the following text to ~/.iourc:")
print("[license]\n" + hostname + " = " + iouLicense + ";\n")
print("You can disable the phone home feature with something like:")
print(" echo '127.0.0.127 xml.cisco.com' >> /etc/hosts\n")
