Enable the SSH service to start after the reboot: # systemctl enable sshd Open the firewall rules to accept incoming traffic on SSH port 22: # firewall-cmd --zone=public --permanent --add-service=ssh Connect to the SSH server with IP eg. 10.1.1.1 as the root user from a remote client machine: $ ssh root@10.1.1.1 It gives me a secure link to any server. It's the only thing I use to admin remote or colocated servers. If you don't know what SSH is, check out this article.

If the /etc/ssh/ssh_config file does not exist or the Protocol option is not set, this is not a finding because the SSH client cannot enforce the Protocol setting on a compliant SSH server. Follow these Cisco IOS CLI commands to configure a hostname, a domain name and to generate RSA keys of 1024 bit length. After generating the RSA keys, Cisco Router/Switch will automatically enable SSH 1.99.

Step 3 – SSHv2 version 2 using Rivest, Shamir, and Adelman (RSA) public-key cryptography; SSHv2 version 2 using the Digital System Algorithm (DSA) Be sure to have an SSHv2 server key-pair with the appropriate version before enabling the SSHv2 service. You can generate the SSHv2 server key-pair according to the SSHv2 client version used.
