Cisco Asa 5505 Generate Ssh Key
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
- Nov 14, 2018 Cisco ASA 5500 Series Configuration Guide using the CLI, 8.4 and 8.6. The following example shows how to generate RSA keys and let a host on the inside interface with an address of 192.168.1.2 access the ASA. The dot appears at the console when generating a server key or decrypting a message using private keys during SSH key exchange.
- 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. Leave a comment. Iam8up / Aug 15 2011. The fact that Cisco doesn’t do this automatically makes me very very nervous. The networks running Cisco appear to be primarily using telnet =(Greg / Aug.
According to this documentation it should be possible to enable an SSH connection to a Cisco ASA 5505. However, it is not possible to ping an IP from the ASA while this has been configured. As it is impossible to ping internally then SSH from another system will work neither. Have idea the minimize command to enable the ssh on ASA 5505 box? I need to enable ping command and ssh so that I could remotely put the configuratoin on the box again. In PIX, i use 'ca gen rsa key 1024' but it no more support anymore.
Sep 06, 2014 Secure Shell (SSH) on the other hand uses port 22 and is secure. SSH uses public key cryptography to authenticate remote user. You can configure SSH access in Cisco ASA device using the steps shown here. The second time I play the album, I sing along with Activate! And it not-so-subliminally makes me think to look for the missing activation key on my Cisco ASA. A Cisco ASA with a Base license, compared with an ASA with a Security Plus license: They can boot with identical image. On the ASA, the command is: crypto key generate rsa 1024 If you leave off the '1024' in the above command, it will use 1024 by default. what interface / VLAN should I need to confgure in order to avoid the minimze purpose.
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
Atlas shrugged galts key to open the generator. 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.
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.
