Далее настроить тему в qt5ct

Нужно создать /etc/hostid -> genhostid.py

#!/usr/bin/python
 
from sys import argv, exit
from struct import pack
 
filename = "/etc/hostid"
 
if len(argv) != 2:
    print("Usage: genhostid.py <hostid>")
    exit(1)
 
if argv[1].startswith("0x"):
    hostid = int(argv[1][2:], 16)
else:
    hostid = int(argv[1])
 
hostid = pack("I", hostid)
open(filename,"wb").write(hostid)

$ sudo python genhostid.py 0x00010203

Далее CiscoIOUKeygen3f.py

# cat /sbin/pidof
#!/bin/sh
ps axc -o pid,command | awk "/`echo $1`/ {print \$1}"

# cat /sbin/killall
#!/bin/sh
kill `/sbin/pidof $1`
