Short and complete guide to configure SSH on and switch for secure remote connection. The Secure Shell (SSH) is a cryptographic network protocol for operating network services securely over an unsecured network. The best-known example application is for remote login to computer systems by users. SSH provides a secure channel over an unsecured network in a client-server architecture, connecting an SSH client application with an SSH server. Common applications include remote command-line login and remote command execution, but any network service can be secured with SSH. The protocol specification distinguishes between two major versions, referred to as SSH-1 and SSH-2. Oct 9, 2018 Let’s enable and configure SSH on Cisco router or switch using the below packet tracer lab. Passport for mac laptop. They are both designed for Mac, though can be easily reformatted to work with Windows. The installation package and source code can be downloaded from winscp.net. Other SSH clients can be found here. WinSCP for Mac. WinSCP is not available for Mac OS. However, other free alternatives are available. For example, Cyberduck and FileZilla are fairly popular alternatives. Main Features. The main features of WinSCP include: Graphical. The configure on a packet tracer lab and real Cisco devices are the same. Just try to learn and do it what the SSH remote authentication needs. Download the packet tracer lab or create your own lab. Configure SSH on Cisco Router or Switch – Technig In this example, I just enable and configure SSH on SW1 and trying to access it from PC1. It’s enough to learn how to configure SSH on Cisco router. R1> R1>enable R1#configure terminal Enter configuration commands, one per line. End with CNTL/Z. R1(config)# R1(config)#ip domain-name Technig.com R1(config)#crypto key generate rsa The name for the keys will be: R1.Technig.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. How many bits in the modulus [512]: 1024% Generating 1024 bit RSA keys, keys will be non-exportable.[OK] R1(config)# *Mar 1 0:5:57.974:%SSH-5-ENABLED: SSH 1.99 has been enabled R1(config)# R1(config)#username Admin password Technig R1(config)#line vty 0 4 R1(config-line)#login local R1(config-line)#transport input ssh R1(config-line)#exit R1(config)#ip ssh version 2 R1(config)#ip ssh authentication-retries 3 R1(config)# R1(config)#ip ssh time-out 120 R1(config)#exit R1#. R1 # That’s all. How to search for a word on a web page mac. Let’s check the process one by one. • I have set DNS domain name with “ IP domain-name” command. • Then configure the router to use RSA key pair with modulus size of 1024 bites for remote service authentication with “ crypto key generate rsa ” command. • Add username “ Admin” with Password of “ Technig” for ssh authentication. • Enabled ssh with “ line vty 0 4” command. • Configure ssh to use local username and password with “ login local” command. Remember that you can set a username and password for ssh with “ username Admin password Technig” command as well. But here we configure ssh to use local username and password.
