Cisco 2811 Generate Rsa Key

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.

Hello, I am replacing a 2621 running RSA encryption with a 2811. I am changing the hostname of the router, which, I am told, will cause me to need to generate a new RSA encryption key on the 2811. I want to confirm whether it is the hostname, the domain name or both that affects the RSA encryption.

Hello, I am replacing a 2621 running RSA encryption with a 2811. I am changing the hostname of the router, which, I am told, will cause me to need to generate a new RSA encryption key on the 2811. I want to confirm whether it is the hostname, the domain name or both that affects the RSA encryption. Using Microsoft Windows Certificate Authority (CA) Certificates on Cisco IOS.

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.

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.

In this example, 192.168.101.2 is the management ip-address of the switch.

Introduction

This document describes how to:

create a certificate signing request (CSR) on the Secure Socket Layer Module (SSLM)
import the certificate using cut and paste in privacy-enhanced mail (PEM) format

Prerequisites

Before you begin, you need to know the domain name that is assigned to the certificate. You also need the Certificates Authorities (CA) root certificate, and possibly the CA intermediate certificate.

Requirements

Before attempting this configuration, ensure that you meet these requirements:

CA root certificate; possibly the intermediate root certificate
domain name for certificate
information

Components Used

The information in this document is based on these software and hardware versions: Win xp pro product key generator.

release 2.1(2)
Verisign Test Certificate

The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, make sure that you understand the potential impact of any command.

Main Task

Task

This section details each step needed to create the CSR, from the creation of the key pair to importing the server certificate.

Step-by-Step Instructions

Complete the instructions in this section.

Create the key pair.
nov10-key is the name of the key pair.
Note: Be sure to specify exportable; otherwise, you are not able to export the key pair from the SSLM.
Create the trustpoint .
/generate-cert-and-key-microsoft-ca.html. The name of the trustpoint is yoursite. You need to enter the subject name in X.509 format and your domain name. This information is used to create the CSR.
Generate the CSR.
Send the CSR to your CA.
Use copy and paste to send the CSR to your CA. If your CA asks for a server type, select Apache.
Load the CA root certificate
Before you can load the server certificate, you must load any CA certificates. At a minimum, this is the CA root certificate, and possibly a CA intermediate certificate. Your CA is able to provide you with the necessary certificates.
Load the server certificate.

Intermediate Certificates

If you have an intermediate certificate, you need to configure two trustpoints. One trustpoint contains the CA root certificate only. You only need to configure enrollment terminal PEM and Certificate Revocation List (CRL) optional. The second trustpoint contains the intermediate certificate and the server certificate. The second trustpoint is configured similar to the first trustpoint, however, instead of the root certificate, use the intermediate certificate.

Verify

There is currently no verification procedure available for this configuration.

Troubleshoot

This section provides troubleshooting information relevant to this configuration.

Cisco 2811 Generate Rsa Key Windows

If you run into problems loading the certificates, enable debugging with the debug crypto pki transactions command.

Make sure you have the complete certificate chain. You can determine this by viewing the certificates on a PC. Save the certificates with a .cer extension, then double click to open them.

The root certificate is shown in Figure 1. You can determine this by looking at the Issued to and Issued by sections. Both sections are the same. Also, note that the certificate is showing up as not trusted because it a test certificate.

The server certificate is shown in Figure 2. You call determine that it matches the root certificate because the Issued by section matches the Issued by section on the root certificate.
