*** Part of the Complete Course: Cisco CCNA to CCNP Transition ***
Whenever I taughtCCNP in theclass-room, I foundthat Students wereconfusedabout some topics or commands that they have studied in the CCNA course(with someone else!), and I had toclarify or re-explainthese topics or commands to them. This is because these topics orcommands are confusing by their nature, or because the way that they are typically explained to the students. Therefore, the idea of this course came in my mind, which intend toclarify those confusing topics or commands.
This course contains two sections:
Working with Passwords: which containsthoughts on passwords, understand themeaning of theno service-encryptioncommand, and how tobreak the type 7 encryption.
Working with Telnet: which contains how to work with telnet as source or destination, and how to telnet to a specific port.
For example, when working with passwords: why do we have two ways to configure the enable password? and why both passwords used in these two ways must be different? Also how can we use the question mark as part of the password? Did you ever try to configure a password like that one?
Another thing is does the no service password-encryptioncommand disable encryption for current or future passwords? or may be both? And how can we break the type 7 encryption, so the encryption configured by the service password-encryptioncommand?
And for Telnet, we will see multiple ways of working with telnet as both the source and the destination, so how to return back to the original host without disconnecting the connection, how to show incoming connections on the destination and the outgoing connections on the source , and also the multiple ways of clearing these connections on either the source or the destination. Finally, we will see how to telnet to a specific port, so to check if BGP or HTTP are working on the remote host for example.
