Hi Friends, Want to know how to remove a key-string which is configured within the command ' crypto key pubkey-chain rsa ' in a router. I dont have to add any other key certificates. Just got a decommission task of removing the crypto configuration and the crypto key.

Packet Tracer – Configure Secure Passwords and SSH Instructor Version

Addressing Table

Scenario

The network administrator has asked you to prepare RTA and SW1 for deployment. Before they can be connected to the network, security measures must be enabled.

Intructions

Step 1: Configure Basic Security on the Router

a. Configure IP addressing on PCA according to the Addressing Table.

b. Console into RTA from the Terminal on PCA.

c. Configure the hostname as RTA.

d. Configure IP addressing on RTA and enable the interface.

e. https://powerfullovely897.weebly.com/blog/lex-and-aria-download. Encrypt all plaintext passwords.

f. Set the minimum password length to 10.

g. Set a strong secret password of your choosing.
Note: Choose a password that you will remember, or you will need to reset the activity if you are locked out of the device.

h. Disable DNS lookup.

i. Set the domain name to CCNA.com (case-sensitive for scoring in PT).

j. Create a user of your choosing with a strong encrypted password.

k. Generate 1024-bit RSA keys.

Note: In Packet Tracer, enter the crypto key generate rsa command and press Enter to continue.

l. Block anyone for three minutes who fails to log in after four attempts within a two-minute period.

m. Configure all VTY lines for SSH access and use the local user profiles for authentication.

n. Set the EXEC mode timeout to 6 minutes on the VTY lines.

o. Save the configuration to NVRAM.

p. Access the command prompt on the desktop of PCA to establish an SSH connection to RTA.

Step 2: Configure Basic Security on the Switch

Configure switch SW1 with corresponding security measures. Refer to the configuration steps on the router if you need additional assistance.

a. Click on SW1 and select the CLI tab.

b. Configure the hostname as SW1.

c. Configure IP addressing on SW1 VLAN1 and enable the interface.

d. Configure the default gateway address.

e. Disable all unused switch ports.

Note: On a switch it is a good security practice to disable unused ports. One method of doing this is to simply shut down each port with the ‘shutdown’ command. This would require accessing each port individually. There is a shortcut method for making modifications to several ports at once by using the interface range command. On SW1 all ports except FastEthernet0/1 and GigabitEthernet0/1 can be shutdown with the following command:

The command used the port range of 2-24 for the FastEthernet ports and then a single port range of GigabitEthernet0/2.

f. Encrypt all plaintext passwords.

g. Set a strong secret password of your choosing.

h. Disable DNS lookup. /github-generate-ssh-key-on-windows.html.

i. Set the domain name to CCNA.com (case-sensitive for scoring in PT).

j. Create a user of your choosing with a strong encrypted password.

k. Generate 1024-bit RSA keys.

l. Configure all VTY lines for SSH access and use the local user profiles for authentication.

m. Set the EXEC mode timeout to 6 minutes on all VTY lines.

n. Save the configuration to NVRAM.
