IPv6 Training (Cisco) Enabling SSH on a Cisco IPv6 Router

Secure Shell or "SSH" is an Application layer convention that utilizes a solid channel; the safe channel guarantees that the information being traded between two IP gadgets is thoroughly secure (encoded).

A Cisco IPv6 switch can either behave like a SSH server or a SSH client. Whenever a Cisco IPv6 switch is behaving like a SSH server, it permits a SSH client (IP gadget) to make a solid, scrambled association with the Cisco switch; and when a Cisco IPv6 switch is behaving like a SSH client, it can make a safe, encoded association with another Cisco switch or to some other IP gadget running as a SSH server.

Presently, before you can empower Secure Shell or "SSH" on a Cisco IPv6 switch, the switch should meet specific prerequisites and those necessities are Sentry MBA 1.4.1.rar:

The switch should be imaged with either an IPsec Data Encryption Standard (DES) or a Triple Data Encryption Standard (3DES) encryption programming picture.
It should be running Cisco IOS Release 12.1(3)T or higher.
It ought to be configured with a host name (by utilizing the worldwide configuration order hostname) and a host space (by utilizing the worldwide configuration order ip area name).
It should as of now have a Rivest, Shamir, and Adelman (RSA) key pair created. The RSA key pair is utilized to consequently empower SSH on the switch; to produce a RSA key pair utilize the "crypto key create rsa" worldwide configuration order.
It should as of now have a client confirmation component configured for nearby or remote access. Presently, with SSH over an IPv6 transport; the main client verification system upheld, is privately put away usernames and passwords. The TACACS+ and RADIUS client verification components are not upheld over an IPv6 transport. However, assuming that you are in an IPv6 network climate and might want to have either TACACS+ or RADIUS verify SSH clients; you should configure TACACS+ or RADIUS over an IPv4 transport and afterward associate with a SSH server over an IPv6 transport.
Here are the means to empower (SSH server) on an IPv6 switch:

Router>enable
Router#configure terminal
Router(config)#ip ssh [timeout seconds | validation retries integer]
Router(config)#exit
Router#copy run start
Steps Explained
Step #1

1. Router>enable

Places switch into Privileged EXEC mode.

Step #2

2. Router#configure terminal

Places switch into Global configuration mode.

Step #3

3. Router(config)#ip ssh break 100 verification retries 2

Configures the SSH (server) control factors on the switch.

Step #4

4. Router(config)#exit

Makes switch exit worldwide configuration mode and reenters into Privileged EXEC mode.

Step #5

5. Router#copy run start

Saves the substance of the running-config to neighborhood Non - Volatile Random Access Memory (NVRAM).

The following are the means that permit a Cisco IPv6 switch that is behaving like a SSH client to start an encoded SSH meeting with a remote systems administration gadget.

Router>enable
Router#ssh [-v {1 | 2}] [-c {3des | aes128-cbc | aes192-cbc | aes256-cbc}] [-l userid | - l userid:{number}{ip-address} | - l userid:rotary{number} {ip-address}] [-m {hmac-md5 | hmac-md5-96 | hmac-sha1 | hmac-sha1-96}] [-o numberofpasswordprompts n] [-p port-num] {ip-addr | hostname} [command]

Steps Explained

Step #1

1. Router>enable

Places switch into Privileged EXEC mode.

Step #2

2. Router#ssh

Starts a scrambled meeting with a remote systems administration gadget.
