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
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.
- Sep 11, 2019 Symptom: restore configuration 'ssh key rsa 2048' with ascii config Conditions: Some customer is using 'ssh key rsa 2048'. They backup configuration as a ascii text (copy startup-config ). So this configuration will reject by 'ssh server is enabled, cannot delete/generate the keys'.
- Sep 18, 2018 In this lesson, we will learn how to configure SSH on Cisco IOS enabled devices. This tutorial will show you how to enable SSH, generating RSA key, and then allowing on SSH remote management protocol under the VTY interfaces.
- Cisco has issued 41 security advisories in one day, which is reportedly the highest one-day disclosure in at least 12 months. On Wednesday, May 1, 2019, the San Jose-based company came out with 41 security alerts, which included a highly critical Nexus 9000 data-center flaw. Other than this critical alert.
- If you don't already have an SSH key, you must generate a new SSH key. If you're unsure whether you already have an SSH key, check for existing keys. If you don't want to reenter your passphrase every time you use your SSH key, you can add your key to the SSH agent, which manages your SSH keys and remembers your passphrase. Generating a new SSH key.
To transfer file in Nexus switches include vrf in the command. Step 4.Generate SSH key on the switch using the idrsa.pub or iddsa.pub. For reference teoh username used. #conf€ (config)#username teoh sshkey file bootflash:idrsa.pub Step 5. You can check command completed successfully. Switch# show user-account teoh user:teoh this user account has no expiry date roles:network-admin ssh public key. Run show crypto key mypubkey rsa to see if you do, in fact, have a key fully generated and registered under a non-default name. If there is, then you can tell the ssh process to use this key with ip ssh rsa keypair-name xxx. If the first command doesn't show anything useful then I'd say you can go ahead and generate a new key.
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.
Mac generate ssh rsa key. Sep 26, 2019 To generate SSH keys in macOS, follow these steps: Enter the following command in the Terminal window. Press the ENTER key to accept the default location. Type in a passphrase. You can also hit the ENTER key to accept the default (no passphrase).
No restarts are necessary.For more details, see on the Red Hat Customer Portal. Ssh generate key ubuntu. Keep in mind that when you a no-cost developer subscription is automatically added to your account. User@domainNow copy the line from ssh-rsa to your user@domain so that’s it is on the clipboard, or put it on a USB stick, or write it onto paper and send it via a delivery pigeon. Using your Red Hat ID, you’ll have access to the articles and knowledgebase on. This is your public key that needs to be added to /.ssh/authorizedkeys on the remote server.On the remote server, do this: $ mkdir /.ssh/$ chmod 700 /.ssh # this is important.$ touch /.ssh/authorizedkeys$ chmod 600 /.ssh/authorizedkeys #this is important.On the remote system, edit /.ssh/authorizedkeys and append the output of the cat command above.Now you should be able to connect from your computer to the remote system.
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. Microsoft office frontpage 2003 product key generator.
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.
After the above configurations, login from a remote machine to verify that you can ssh to this cisco switch.
Generate Ssh Key Mac
In this example, 192.168.101.2 is the management ip-address of the switch.
