Unetlab/Eve-NG: Cisco IOU License Generator

Скрипт для генерации лицензии под образы IOU

Сделайте скрипт исполняемым

$ chmod +x CiscoKeyGen.py

и выполните

$ ./CiscoKeyGen.py 

Содержание скрипта:

#!/usr/bin/python 
print "\n*********************************************************************" 
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 = '\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('!L', ioukey) + iouPad1
iouLicense = hashlib.md5(md5input).hexdigest()[:16]  # add license info to $HOME/.iourc 
print "\n*********************************************************************"
print "Create the license file $HOME/.iourc with this command:"
print " echo -e '[license]\\n" + hostname + " = " + iouLicense + ";'" + " | tee $HOME/.iourc "
print "\nThe command adds the following text to $HOME/.iourc:"
print "[license]\n" + hostname + " = " + iouLicense + ";"
# disable phone home feature 
print "\n*********************************************************************"
print "Disable the phone home feature with this command:"
print " grep -q -F '127.0.0.1 xml.cisco.com' /etc/hosts || echo '127.0.0.1 xml.cisco.com' | sudo tee -a /etc/hosts"
print "\nThe command adds the following text to /etc/hosts:"
print "127.0.0.1 xml.cisco.com"
print "\n*********************************************************************"

Второй вариант для интепретатора python3

Скрипт будет чуть изменен, поскольку print является функцией в этой версии python
Использовать так:

$ chmod +x CiscoIOUKeygen3f.py
$ python3 CiscoIOUKeygen3f.py

Содержание скрипта:

#! /usr/bin/python3
print("*********************************************************************")
print("Cisco IOU License Generator - Kal 2011, python port of 2006 C version")
import os
import socket

for x in hostname:
    ioukey = ioukey + ord(x)
print("hostid=" + hostid + ", hostname=" + hostname + ", ioukey=" + hex(ioukey)[2:])
# create the license using md5sum

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")
with open("iourc.txt", "wt") as out_file:
    out_file.write("[license]\n" + hostname + " = " + iouLicense + ";\n")
print("^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^\nAlready 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")
