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

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. Aug 22, 2013 myswitch(config)# crypto key generate rsa The name for the keys will be: myswitch.thegeekstuff.com Choose the size of the key modulus in the range of 360 to 2048 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. 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 telne. Generate a 2048-bit rsa keypair: seclab-3650 ( config)#crypto key generate rsa modulus 2048 label 2048-bit-key 2. Create a trustpoint specifying self-signed enrollment and telling the TP to use that keypair.

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.

$ cd /.ssh $ ls authorizedkeys2 iddsa knownhosts config iddsa.pub You’re looking for a pair of files named something like iddsa or idrsa and a matching file with a.pub extension. The.pub file is your public key, and the other file is the corresponding private key. If you don’t have. Apr 02, 2019  ssh-keygen -p -o -f /root/.ssh/idrsa. The path /root/.ssh/idrsa is the path of the old private key file. The above steps shall help you install SSH keys on any virtual private server in a completely safe, secure and hassle-free manner. Generate ssh key id_rsa. You can generate SSH key pairs for root in WHM Home Security Center Manage root's SSH Keys. Click Generate a New Key to get started. There are several fields on this page: Key Name, Key Password, Key Type, and Key Size. The default Key Name is idrsa. If you see an existing public and private key pair listed (for example idrsa.pub and idrsa) that you’d like to use, you can skip Step 2 and go straight to Step 3. Step 2: Generate a new SSH key With your command line tool still open, enter the text shown below.

Now we can generate the RSA keypair: R1(config)#crypto key generate rsa The name for the keys will be: R1.NETWORKLESSONS.LOCAL Choose the size of the key modulus in the range of 360 to 4096 for your General Purpose Keys. Choosing a key modulus greater than 512 may take a few minutes. Now at command line you can fix this with a ‘Crypto Key Generate RSA Modulus 2048‘ command, but you can’t get to command line only ASDM. On older versions of the ASDM you could generate the keypair in the Identification Certificates section (well you still can but only if you are also generating a certificate request file).

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.

Generate A Rsa Crypto Key

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.
