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

By | May 14, 2019

Secure Shell or “SSH” is an Application layer protocol that makes use of a at ease channel; the at ease channel guarantees that the facts being exchanged between IP devices is absolutely cozy (encrypted). como configurar tp link extender .

A Cisco IPv6 router can either act like a SSH server or a SSH client. When a Cisco IPv6 router is acting like a SSH server, it lets in a SSH customer (IP tool) to make a comfortable, encrypted connection to the Cisco router; and when a Cisco IPv6 router is appearing like a SSH consumer, it could make a comfy, encrypted connection to any other Cisco router or to some other IP device jogging as a SSH server.

Now, earlier than you could enable Secure Shell or “SSH” on a Cisco IPv6 router, the router need to meet sure requirements and people requirements are:

The router have to be imaged with both an IPsec Data Encryption Standard (DES) or a Triple Data Encryption Standard (3DES) encryption software program photo.
It ought to be going for walks Cisco IOS Release 12.1(three)T or higher.
It need to be configured with a bunch name (via using the worldwide configuration command hostname) and a bunch area (by the use of the worldwide configuration command ip area-name).
It ought to already have a Rivest, Shamir, and Adelman (RSA) key pair generated. The RSA key pair is used to routinely enable SSH on the router; to generate a RSA key pair use the “crypto key generate rsa” global configuration command.
It should have already got a person authentication mechanism configured for neighborhood or remote access. Currently, with SSH over an IPv6 delivery; the only user authentication mechanism supported, is regionally saved usernames and passwords. The TACACS+ and RADIUS person authentication mechanisms aren’t supported over an IPv6 delivery. But, if you are in an IPv6 community environment and would love to have both TACACS+ or RADIUS authenticate SSH clients; you should configure TACACS+ or RADIUS over an IPv4 shipping after which connect with an SSH server over an IPv6 transport.
Here are the stairs to enable SSH (SSH server) on an IPv6 router:

Router>permit
Router#configure terminal
Router(config)#ip ssh [timeout seconds exit
Router#copy run begin
Steps Explained
Step #1

  1. Router>permit

Puts router into Privileged EXEC mode.

Step #2

  1. Router#configure terminal

Puts router into Global configuration mode.

Step #three

three. Router(config)#ip ssh timeout 100 authentication-retries 2

Configures the SSH (server) control variables at the router.

Step #four

  1. Router(config)#exit

Causes router to exit global configuration mode and re-enters into Privileged EXEC mode.

Step #five

five. Router#reproduction run start

Saves the contents of the walking-config to nearby Non -Volatile Random Access Memory (NVRAM).

Below are the steps that permit a Cisco IPv6 router that is performing like a SSH patron to initiate an encrypted SSH session with a far flung networking tool.

Router>permit
Router#ssh [-v 1 ] [-c aes128-cbc ] [-l userid numberip-address number ip-address] [-m hmac-sha1-96] [-o numberofpasswordprompts n] [-p port-num] hostname [command]

Steps Explained

Step #1

  1. Router>enable

Puts router into Privileged EXEC mode.

Step #2

  1. Router#ssh

Initiates an encrypted consultation with a remote networking tool.
