Pero al enrollar mi terminal genera una llave de 512 bits. Porque puede ser eso? Oct 02, 2015  SSH Config and crypto key generate RSA command. Use this command to generate RSA key pairs for your Cisco device (such as a router). Keys are generated in pairs–one public RSA key and one private RSA key. If your router already has RSA keys when you issue this command, you will be warned and prompted to replace the existing keys with new keys. I did a little research and found out that if I removed the rsa key by using this command ' crypto key zeroize rsa' and then added the 'crypto key generate rsa generate-keys modulus 1024, then that would work. Any thoughts? No service pad. No service password-encryption. Hostname Sales-SW-ACC2. Ip domain name my.company.come.

I have two Cisco Catalyst 2960-S 48-port switches 'stacked' using the Cisco FlexStack module. Originally I had to set them up using 'Express Setup', which I absolutly hate from my limited use of it.
I configured hostnames, ip addresses, and made sure the stack was functioning properly. I tested by plugging in a laptop and making sure it could open an internet page and all was well. I configured each switch exactly the same with the exception (obviously) of the hostname and IP. I then powered them OFF and installed the stacking module and they auto-configured themselves..
Before:
Switch-A (192.168.10.3)
Switch-B (192.168.10.4)
After:
Switch-A (192.168.10.3) Master 1
Switch-B Member 2
What I need and want to do now is setup remote access. If I have to go connect up with a console cable to configure that's fine, but I'm not sure if I need to..
If I open PuTTY and use Telnet to connect it states 'password required, but none set' and the PuTTY window closes.
If I open PuTTY and use SSH to connect it prompts me 'login as:'
If I press enter (@192.168.10.3's password:) it proceeds to prompt me for a password, which entering the password I used to setup the switch I receive 'access denied'.
I know I didn't configure SSH or Telnet for that matter when I initially set these up. I want to fix that now.
I want SSH (v2) enabled and I want to disable Telnet.
Any suggestions?

Telnet versus SSH

Many people continue to use Telnet for sensitive applications or access to critical systems. Telnet is CLEARTEXT, so all the data, including the login id is visible is someone intercepts that session

Here’s what this looks like using Wireshark an Open Source Protocol Analyzer when we use the Follow TCP Stream feature in Wireshark.

You clearly see the User Verification Prompt.Here's the telnet trace file.

How to Enable SSH Version 1 on Cisco

Before you can enable SSH you need to assign individual (or group) user IDs and passwords.

These are just login id's and are required regardless if you use Telnet or SSH.

To enable locally administered user IDs, use the following set of configuration commands. I would not suggest using the nopassword parameter.

Put your own data in the italized text.

Crypto Key Generate Rsa Command

Now when you telnet into the device you should see the Username prompt

Now that you have login id's created you can turn on SSH version 1.

To enable SSH, use the following set of configuration commands. I would not suggest using the nopassword parameter.

Put your own data in the italized text.

Now we'll try to capture the SSH login and as you can see the login data is no longer in clear text. Here's the SSH 1 trace file.

The moral of the story is not to use Cleartext logins if the device or application is sensitive.

To upgrade to even more secure SSH version 2, type in the following commands
