2、導入gns3 vm（分vmware esxi和vmware workstation pro版本）
vmware esxi版本：
部署中…
開機：
回車配置：
問題：沒有開啟kvm。
將虛擬機關機，開啟esxi的虛擬化透傳。
關機中。。。
再重新開機。。。
回車再重啟，kvm已經啟用。
配置固定ip地址（根據實際情況修改）：
auto eth0
# Comment this line to disable DHCP #iface eth0 inet dhcp //注釋這一行 # Uncomment this lines if you want to manually configure network # It's not recommended if you can avoid it. # iface eth0 inet static //取消注釋 address 192.168.0.50 netmask 255.255.255.0 gateway 192.168.0.1 dns-nameservers 192.168.0.1 //改為114.114.114.114等dns
Ctrl+x
輸入y
回車
檢查：
esxi版本完。
——————————————————————
vmware workstation pro版本：
vmware workstation pro安裝完畢。
選擇一個目錄：
開啟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 //關閉dhcp # Uncomment this lines if you want to manually configure network # It's not recommended if you can avoid it. # iface eth0 inet static //配置靜態ip地址 address 192.168.92.100 netmask 255.255.255.0 gateway 192.168.92.1 dns-nameservers 114.114.114.114
地址配置完畢會自動重啟！
連接gns3 vm：
重啟gns3 client。
上傳鏡像：
—–vmware workstation pro版本完
3、windows 安裝GNS3-2.1.21-all-in-one.exe
需要Update for Universal C Runtime in Windows：根據系統下載。
windows 7 x64下載：
安裝wireshark，狂點下一步。。。
正式安裝gns3-ui：
安裝完畢。
—————————————————————
4、基本配置：Edit—>Preferences
關聯scrt：
關聯vnc：
項目路徑：
應該是禁止任何中文字元。
安裝scrt：狂點下一步。。。
破解方法：自行搜索。
gns3 client連接gns3 vm：
判斷連接成功：
環境準備完——————————–完
5、上傳路由器IOU的鏡像：
鏡像導入成功，但是沒有license，還不能用。
下一步，ssh登錄至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
將軟體粘貼至gns3客戶端軟體中：
拖出兩台路由器測試：

附CiscoIOUKeygen.py源碼
#! /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'x4Bx58x21x81x56x7Bx0DxF3x21x43x9Bx7ExACx1DxE6x8A' iouPad2 = b'x80' + 39*b' ' 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/hostsn")
