How to Configure SSH on Cisco IOS


How to Configure SSH on Cisco IOS Secure Shell (SSH) is a protocol which provides a secure remote access connection to network devices. Communication between the client and server is encrypted in both SSH version 1 and SSH version 2. Implement SSH version 2 when possible because it uses a more enhanced security encryption algorithm. Requirements The Cisco IOS image used must be a k9(crypto) image in order to support SSH. For example c3750e-universalk9-tar.122-35.SE5.tar is a k9 (crypto) image.

Configuring Cisco ISE for Public Key Authentication


Configuring ISE for Public Key Authentication Users are now able to be authenticated using Public Key Authentication. When authentication using public key is enabled, password-based user authentication is disabled. The public key authentication mechanism can be disabled at any time. Do not execute the command 'service sshd PubkeyAuthentication' if you do not have a public key to import into ISE. This disables password-based authentication and Cisco ISE will expect you to login using a private key. If you do run into this issue, you need to use the console port to login into Cisco ISE and disable Public Key Authentication with the command 'no service sshd PubkeyAuthentication'. Create the SSH Public Key: ssh-keygen Enable SSH Public Key Encryption: service sshd PubkeyAuthentication Import Public Key File: crypto key import [public key filename] repository [repository name] Repository URLs now require an inconvenient space, here's why: There are three elements to the command, - url - tells ISE that you are configuring the repository url - ftp: - specifies the protocol to be used - //ip address - is the path to the repository given the protocol stated url ftp: //[IP address] ISE has a new CLI system and some commands will be different.

If following this lab as per my SVPN lab course then this lab follows on from my DMVPN Phase 3 Hub & Spoke configuration, however it can also be followed separately for those just interested in a IOS CA and SCEP enrolment demo. DMVPN Hub and Spoke Configuration Video can be found at the following link: 🤍 Public Key Infrastructure (PKI) is utilised throughout information security for identity management and authentication where an entity joins a PKI and establishes a trust boundary. This video details creating an IOS Certificate Authority (CA) to issue certificates to end devices for identity management and to establish a trust. The typical reasoning is to authenticate using Rivesr-Sharmin-Alderman (RSA) or Elliptic Curve Digital Signature Algorithm (ECDSA) when exchanging Internet Key Exchange messages to establish a Virtual Private Network. Signature authentication using PKI is a scalable authentication method in which the keys are cryptographically stronger keys then pre-shared authentication.

[Tutorial] How to enable SSH on Cisco Routers on GNS?


For enabling SSH on cisco router, Firstly, we have change the hostname from default and set a ip domain name which is required to generate RSA key pairs, it prompt to ask the size of the key in bits that i have entered 1024 bits. These key pairs are required to establish an SSH connection. Secondly we have to create some credentials with certain privilege level, as you guys can see i have created two, one with default and other with privilege level 15. Then i have changed SSH version to 2. Lastly we need to enable VTY lines and issue command "login local" and "transport input ssh". Now the router is SSH enabled and we can access it on other devices. On R2, the command to access R1 via SSH is "ssh -l *username* *ip_of_R1*" "-l" this option requires a username to initiate ssh connection R1_SSH_Configuration: ##hostname LabRouter ##ip domain-name ##crypto key generate rsa // it will prompt asking the size ##username cisco password cisco ##username sshv1 privilege 15 password cisco ##ip ssh version 2 // changing SSH version ##line vty 0 6 // Enabling 7 vty lines ##login local ##transport input ssh // Enable SSH input ##end Accessing R1 on R2 via SSH: ##ssh -l cisco // accessing by user cisco ##ssh -l sshv1 // accessing by user sshv1 If you want to do more with SSH, just type " ip ssh ? " in configuration mode. There will be a list of commands, so use them to change the parameters such as default port or timeouts, etc. PS: password, username and domain name can be anything you want to, just remember username and passwords are case sensitive.

MicroNugget: AAA, TACACS+, and SSH


Start learning cybersecurity with CBT Nuggets. 🤍 In this video, Keith Barker covers how to set up a router to authenticate users and restrict access to the secure shell (SSH). He begins with a router that has no security in place and uses TACACS+ to pair it with an AAA server. Keith covers a lot of ground in this short video, walking you through locking down an unsecured router using a AAA server and TACACS+. He uses a straightforward checklist with eight simple steps, beginning with enabling secret on the router and then moving on to create a local user just in case a AAA server can’t be reached. The next steps are to set the domain name and create an RSA public/private key pair to establish SSH access. All of this lays the groundwork so you can enable the router to access a triple-A server. You’ll specify which AAA server you want to use, along with the key, then move on to select a default method for authenticating users. 🌐 Download the Free Ultimate Networking Cert Guide: 🤍 ⬇️ 13-Week Study Plan: CCNA (200-301): 🤍 Start learning with CBT Nuggets: • Microsoft Windows Server 2016 Installation, Storage, and Compute (70-740) | 🤍 • Microsoft MCSA: Windows Server 2016 | 🤍 • All Windows Server 2008 | 🤍 • All Windows Server 2016 | 🤍

Never use TELNET ! How to configure SSH on a Cisco Router.


Welcome to Network Engineer Pro. I'm Rafael, CCIE #64356. I'm working on ton of content (videos, labs and more) to help you learn networking.

Routing TCP/IP, Volume 1 ➤ 🤍 Routing TCP/IP, Volume 2 ➤ 🤍 TELNET should never be used in a production network it's unsecure and the data can easily be seen in a packet capture. I show you this live on the cli. After telnetting to another router, the wireshark capture is examined and we can easily see the data being sent across including the usernames, passwords and more. The more secure way to remotely manage devices is to use SSH. SSH is a network protocol used to remotely access and manage a devices. The main difference between Telnet and SSH is that SSH uses encryption, which means that all data transmitted over a network is secure from eavesdropping. After SSH is configured and tested, I go back to the wireshark capture for analysis and we can see the data going across is encrypted. This is what you want especially in production environments. I hope everyone enjoyed the video, if you did be sure to like and subscribe.
