How to generate Cisco IOU license key in Eve ng

[@aceraspire7160]

I was almost determined to give up using this laboratory, I'm not kidding. I even downloaded malware yesterday trying to find these two files. but thank god your video gave me the solution; made me want to continue. * Sorry if I made a typo. I don't speak English, and I used the Google translator to be able to post here on your video. Thank you very much brother, very grateful to share your knowledge. A hug. God be with you

[@dark_mystic2267]

I was in the same boat as Acer Aspire. I was ready to give up on Eve-NG as the IOL L2 and L3 Switch images were not starting (only 7200 Dynamips router image was working). But, this worked and I now able to use the Switches as well. Many thanks for your excellent step-by step video.

Thank you for comment

Helpful even after 5 years.....

[@emr1d341]

You're the best! Thank you so much! I actually had to tweak a couple things, but I eventually got it to work. Trying to fixpermissions using "/wrappers//unl wrapper" didn't seem to work, but a single "/" instead of "//" worked. I couldn't copy/paste license with a mouse (OracleVM). I was able to use FileZilla a .txt over and rename it. (Actually, the keygen I copy/pasted from your site didn't work, but I was able to find another one.) Ultimately, your guide got me to where I needed to get! Thanks a million! My future children also thank you.

am still struggling in 5:39 , i cant view the license after typing the code sudo ./CiscoKey.py

[@emr1d341]

I had the same issue. I think the problem was with the license. Here's what I ended up using. #! /usr/bin/python print "************************************************************************" print "Cisco IOU License Generator v2 - Kal 2011, python port of 2006 C version" 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='\x4B\x58\x21\x81\x56\x7B\x0D\xF3\x21\x43\x9B\x7E\xAC\x1D\xE6\x8A' iouPad2='\x80' + 39*'\0' md5input=iouPad1 + iouPad2 + struct.pack('!Q', ioukey)[4:] + iouPad1 iouLicense=hashlib.md5(md5input).hexdigest()[:16] print "************************************************************************" print "Add the following text to ~/.iourc:" print "[license] " + hostname + " = " + iouLicense + "; " print "************************************************************************" print "You can disable the phone home feature with something like:" print " echo '127.0.0.127 xml.cisco.com' >> /etc/hosts" print "************************************************************************"

Fixed the issue by converting the script to python3 and also modifying some of the config: Steps: > vi Ciscokey.py press i for insert ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ #! /usr/bin/python3 print("*********************************************************************") print("Cisco IOU License Generator - Kal 2011, python port of 2006 C version") 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(" Add the following text to ~/.iourc:") print("[license] " + hostname + " = " + iouLicense + "; ") with open("iourc.txt", "wt") as out_file: out_file.write("[license] " + hostname + " = " + iouLicense + "; ") print("^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Already copy to the file iourc.txt ") print("You can disable the phone home feature with something like:") print(" echo '127.0.0.127 xml.cisco.com' >> /etc/hosts ") ++++++++++++++++++++++++++++++ press escape to get of insert mode !wq ! Grant execution permission: > chmod +x Ciscokey.py !Generate the key: > python3 Ciscokey.py Now you can use the generated key and save in iourc nano -c iourc End Good Luck:

Hi, Thanks for the video. How could we paste the script on Windows while running VMware Workstation 15 Player. I open the GNU nano 2.5.3 but I can't R-click or use Ctrl+V

Not within VMware. SSH into the session and paste into it.

I had the same issue. I created a .txt on my computer, used FileZilla to get it to the right location in the vm, then renamed it. For the license itself (in the ioruc), I screenshotted and manually input.
