Educational purpose
The tutorials on Technical Hakim are for learning purposes only. I test the labs in Cisco Packet Tracer, GNS3 or on my own equipment, but your hardware, software versions and network may behave differently.
Use at your own risk
Commands such as password recovery, erasing configurations or firewall changes can disrupt a live network. Practise in a lab first. On production equipment, follow your organisation's change procedures and back up the configuration first. I am not responsible for any loss or damage from using the information on this blog.
Accuracy
I try to keep posts accurate and up to date, but technology changes. If you spot an error, please let me know and I will correct it.
