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.

Cisco ASA SSH, Don’t Forget To Generate A Key. It looks like you need to generate an RSA key for SSH: 1 crypto key generate rsa modulus 1024: Filed under Cisco, Cisco ASA, Networking, Security. 6 Comments leave a comment. Iam8up / Aug. Define AAA lists for ssh: ASA(config)#aaa authentication ssh console LOCAL. Generate crypto key pair to use with SSH server: ASA(config)#domain-name grandmetric.labs ASA(config)#crypto key generate rsa general-keys modulus 1024. In addition you can set the allowed sources, and define on which interface ssh will be allowed.
1. Setup Management IP
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. 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. As covered in my old post, to enable SSH on the ASA, we’ll need to generate RSA key pair first. Current NIST recommendation is to use 2048-bit or above. In this post, I am going to use 4096-bit key pair. ASA5506(config)# crypto key generate rsa modulus 4096 SSH Version. Configuring the Cisco ASA SSH server to accept only version 2 is best. Dec 26, 2013 crypto pki certificate chain TP-self-signed-##### certificate self-signed 01 (here would be numerous 8 digit Alpha-Numeric strings) quit. Just a reminder i am new to networking securities and it is alot to take in. Edit: also are these 2 commands the same? Crypto key generate rsa. Ip ssh rsa keypair-name sshkeyskeys.
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.
Cisco Ssh Commands
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.
