How to enable SSH on Cisco Routers and Switches

cisco crypto key generate rsa modulus 2048

Hi I've been using the below script for the last 8 months on an 881 with 15. Before you issue this command, ensure that your router has a hostname and a domain name configured with the hostname and ip domain-name global config commands. You can specify other modulus sizes with the modulus keyword. You can do it by getting a certificate that uses the keys, then exporting a certificate bundle with private key included. Anyone able to sniff that traffic would see your password and any other information sent during the Telnet session. Without special-usage keys, one key is used for both authentication methods, increasing the exposure of that key.

To make the keypair named 'my-imported-key', import it like this, pasting in the text blob when prompted, then typing 'quit'. Switch config crypto key generate rsa The name for the keys will be: switch. Choose the size of the key modulus in the range of 360 to 2048 for your Encryption Keys. Get answers and train to solve all your tech problems - anytime, anywhere. Longer key lengths provide greater security but take more time to generate.

Finally, typing ctri-z or end exits configure mode completely and returns the prompt to enable mode. Are you sure its actually being ran? Configure a client authentication method. New Visitors are encouraged to read our. The private key output contains both the private and public keys. Export that certificate to the terminal. The signature, encryption and on keywords and devicename : argument were added.

Kill those off just like before. Choosing modulus greater than 512 will take longer time. Final Words Hopefully, this will be included in your standard configuration for all Cisco routers and switches that you have. The label is important, I'll tell you! I've got an existing key, but due to the changes in the new config? The label is referenced by the trustpoint that uses the key pair. However, a longer modules take longer to generate see the table below for sample times and takes longer to use. Command Modes Global configuration Command History Release Modification 11.

When I'm ready, I'll copy the config from flash over to the startup config so that when it boots back up, it becomes a different router. Configure a domain name, unless this was done previously. Here's what I did: gill config hostname gill gill config ip domain-name taosecurity. Hi, If it was working for years! Because the key modulus is not specified, the default key modulus of 1024 is used. Router config crypto key generate rsa general-keys The name for the keys will be: myrouter. But there's no command of which I'm aware to directly export the keys either. Set the privilege level to 0, and set the exec-timeout period to 9 minutes and 0 seconds to disconnect idle connections to these lines.

A length of less than 512 bits is normally not recommended. When you connect to the server, your client will see this: debug1: Remote protocol version 2. You use the command key-string followed by a carriage return to begin entry of the remote peer's public key. The majority, if not all, of the people, know that Telnet sends data in clear text. Choosing a key modulus greater than 512 may take a few minutes.
