Creating a Self-Signed Certificate using the router's name as the! Label and using 1024bit encryption key. The label is important, I'll tell you! In a minute why C1801 (config)# The name for the keys will be: C1801% The key modulus size is 1024 bits% Generating 1024 bit RSA keys, keys will be non-exportable. When you use the crypto key generate rsa command, it will ask you how many bits you want to use for the key size. How much should you pick? It’s best to check the next generation encryption article from Cisco for this. At this moment, a key size of 2048 bits is acceptable. Key sizes of 1024 or smaller should be avoided. How I create RSA key and enable SSH access in Cisco VG202, in a Cisco router I use the next commands(but in a VG not exists): conf t. Crypto key generate rsa modulus 1024 ip domain-name domain-name ip ssh version 2 ip ssh time-out 120 ip ssh authentication-retries 3 line vty 0 4 transport input telnet ssh end.

Step 4: Erase existing key pairs on the router. R1(config)# crypto key zeroize rsa Note: If no keys exist, you might receive this message:% No Signature RSA Keys found in configuration. Step 5: Generate the RSA encryption key pair for the router. Crisis core download. The router uses the RSA key pair for authentication and encryption of transmitted SSH data. The crypto key generates RSA command is something that will be dependent on the IP domain name commands and the hostname. The crypto command can be used in order to generate a key pair which will have a private and public RSA key. Aug 22, 2013 friends i have found way to disable SSH from cisco device generally we use no before any command to remove that perticular command, Do notice if you use the command “no crypto key generate rsa” it will not work rather the device will suggest you to use the ‘crypto key zeroize rsa’ command, amazing.!!!!! May 20, 2014  Author, teacher, and talk show host Robert McMillen shows you how to use the Cisco ASA version 9 generate RSA keys command.

Problem

I was working on a Cisco 3750-G last week, and I was in the process of setting up SSH access. When I went to generate the crypto key and enable SSH, It fired an error at me. In fact it wouldn’t execute any crypto commands;

Now I have seen this before, (but not for a while). You need to be running a K9 version of the code. A quick ‘show version‘ will tell you.

Solution

So you can either, just use TELNET to manage the switch, or upgrade it to a K9 version of the code, (in my case c3750-ipserviceslmk9-tar.122-55.SE11). I chose to upgrade.

Upgrade Cisco Catalyst 3750G

First I tried to TFTP in the bin file, but I kept getting a lot of ‘O’ (‘out of sequence’ errors,) and the process failed. After discussions with a colleague, he recommended I simply use the archive-download command and use the TAR upgrade file instead.

WARNING: These old G series switches only have a 16MB flash in them, the TAR file is about 13.5MB you will need to delete the boot file and folder from flash to upgrade the IOS, but I suggest you copy the bin file out to TFTP in case theres a drama, and you need top copy it back in, before you continue. (In fact backup the switch config as well to be on the safe side!)

Setup your TFTP server, and download your image (c3750-ipserviceslmk9-tar.122-55.SE11.tar).

Delete the .bin file from the flash on the switch, and any associated folders (NoteWarhammer dawn of war 2 cd key generator. : to delete a folder, the syntax is different). Obviouly you may have different files and folders.

Perform the upgrade;

It can take 10 minutes or so, but when complete, check the boot variable is set to the new image, and then reload the switch (It may restart a couple of times that’s OK).
