Jun 28, 2007 ip domain-name rtp.cisco.com!- Generate an SSH key to be used with SSH. Crypto key generate rsa ip ssh time-out 60 ip ssh authentication-retries 2. At this point, the show crypto key mypubkey rsa command must show the generated key. After you add the SSH configuration, test your ability to access the router from the PC and UNIX station. Aug 22, 2013. Run show crypto key mypubkey rsa to see if you do, in fact, have a key fully generated and registered under a non-default name. If there is, then you can tell the ssh process to use this key with ip ssh rsa keypair-name xxx.If the first command doesn't show anything useful then I'd say you can go ahead and generate a new key. Nov 17, 2016 hello everyone. Today I will show you how to login Cisco router using ssh key. We will enable ssh on the router and then generate a key on an Ubuntu Linux server and using that key we will login to our router. The process is easy, lets start. Change the hostname of the router. Follow the below procedure to change the hostname of the router. R1(config)#crypto key generate rsa modulus 2048 The name for the keys will be: R1.NETWORKLESSONS.LOCAL% The key modulus size is 2048 bits% Generating 2048 bit RSA keys, keys will be non-exportable. OK (elapsed time was 24 seconds)%SSH-5-ENABLED: SSH.
Nov 23, 2011 Do you really want to remove these keys? yes/no: yes. Then try generating a new RSA keypair anew: configure terminal. Crypto key generate rsa label ssh modulus 1024. The name for the keys will be: ssh% The key modulus size is 1024 bits% Generating 1024 bit RSA keys, keys will be non-exportable. OK (elapsed time was 3 seconds). SSH Public Key Authentication on Cisco IOS PKI (Public Key Authentication) is an authentication method that uses a key pair for authentication instead of a password. Two keys are generated.
Q: I have a Cisco switch in my network, which I can access by hooking up a console cable directly to the device. I like to access the switch remotely using SSH. How can I enable ssh on my Cisco 3750 Catalyst Switch?
A: By default, when you configure a Cisco device, you have to use the console cable and connect directly to the system to access it. Follow the steps mentioned below, which will enable SSH access to your Cisco devices. Once you enable SSH, you can access it remotely using PuTTY or any other SSH client.
1. Setup Management IP
First, make sure you have performed basic network configurations on your switch. For example, assign default gateway, assign management ip-address, etc. If this is already done, skip to the next step.
Cisco 3560 Replacement
In the following example, the management ip address is set as 192.168.101.2 in the 101 VLAN. The default gateway points to the firewall, which is 192.168.101.1
2. Set hostname and domain-name
Next, make sure the switch has a hostname and domain-name set properly.
3. Generate the RSA Keys
The switch or router should have RSA keys that it will use during the SSH process. So, generate these using crypto command as shown below.
Also, if you are running on an older Cisco IOS image, it is highly recommended that you upgrade to latest Cisco IOS.
4. Setup the Line VTY configurations
Setup the following line vty configuration parameters, where input transport is set to SSH. Set the login to local, and password to 7.
If you have not set the console line yet, set it to the following values.
5. Create the username password
If you don’t have an username created already, do it as shown below.
Note: If you don’t have the enable password setup properly, do it now.
Make sure the password-encryption service is turned-on, which will encrypt the password, and when you do “sh run”, you’ll seee only the encrypted password and not clear-text password.
5. Verify SSH access
From the switch, if you do ‘sh ip ssh’, it will confirm that the SSH is enabled on this cisco device.
After the above configurations, login from a remote machine to verify that you can ssh to this cisco switch. Sap r3 license and object key generator.
In this example, 192.168.101.2 is the management ip-address of the switch.
