To enable sshv2 only

Create a user in the local database using command “ username…secret”. Allow only SSH By default, the SSHv2 server is enabled on the Cisco CG-OS router. You can disable the SSHv2 server to prevent SSHv2 access to the Cisco CG-OS router. Note To reenable SSHv2, you must first generate an SSHv2 server key. (See Generating SSHv2 Server Keys, page 5-4.) BEFORE YOU BEGIN In the above output, the system is showing SSH support, but it’s currently disabled as no RSA key has been generated. It is also worth noting that a key of at least 768 bits must be generated to enable SSHv2. Securing Access to Router.

This alone should make sure that the SSH is able to run in SSHv2. In addition, I have given the keypair a special name that can be used to select it in diverse applications. We can make sure that SSH is using this particular RSA keypair using these commmands: configure terminal.

Here, I will show the primary rules of establishing a secure service, getting firewall access, and tunnel forwarding on Linux. Hi guys, I've been task with upgrading some routers to SSH2 (from V1). Now I know this can be solved by using the #ip ssh version 2 command.

First, if SSH v1 was initially configured on the firewall, then all SSH keys from version 1 must be deleted. This can be done using the command "delete ssh device all". Example: 350-2-> delete ssh device all Delete ssh sessions To ensure the integrity of your system, you should configure the SSH daemon to accept only SSHv2 connections. To configure the SSH daemon to only use SSHv2 protocol ensure the following line is in the sshd_config file and not commented out. Protocol 2. NOTE: Versions of Red Hat and CentOS after 7.4 use SSHv2 by default.
