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

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.

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.

Fixed the issue by converting the script to python3 and also modifying some of the config:


Steps:

> vi Ciscokey.py

press i for insert

<copyy paste the text below>



#! /usr/bin/python3

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

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 =
iouPad2 = b'\x80' + 39*b'\0'
md5input=iouPad1 + iouPad2 + struct.pack('!I', ioukey) + iouPad1


print("\nAdd the following text to ~/.iourc:")
print("[license]\n" + hostname + " = " + iouLicense + ";\n")
with open("iourc.txt", "wt") as out_file:
out_file.write("[license]\n" + hostname + " = " + iouLicense + ";\n")
copy to the file iourc.txt\n ")

print("You can disable the phone home feature with something like:")
print(" echo '127.0.0.127 xml.cisco.com' >> /etc/hosts\n")





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:

Donde puedo conseguir el script para generar la licencia

[bravealikhan]

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

[FatzyRider]
