Once connected to a server, you can interact with files and folders anywhere on the remote filesystem. Do you have any tips/tricks for speeding up SSH connections. Enable SSH to start automatically after each system reboot by using the systemctl command: Enterprise-Grade Dedicated Servers Starting at Only $199.00 $90.00/mo. I am using RHEL 7 and 8 Linux hosts to configure Host based authentication. Outlet Servers Starting at Only $30.00/mo. The above configuration (Host *) will enable connection re-use for all remote servers you connect to using these directives: You can enable this for connections to a specific remote server, for instance: This way you only suffer the connection overhead for the first connection, and all subsequent connections will be much faster. Here rhel-7 will be my client using which I will initiate the SSH connection while rhel-8 will act as a server. Authenticated to rhel-8.example.com ([10.10.10.7]:22).

You can try to connect from rhel-7 to rhel-8 using any user, You can also try to connect using a non root user.

More details on SSH Public Key Authentication (with and without password) in Linux. CertificateFile Specifies a file from which the user's certificate is read. 5. copy running-config startup-config.

So you can consider forcing ssh connections over IPv4 only, using the syntax below: Alternatively, use the AddressFamily (specifies the address family to use when connecting) directive in your ssh configuration file /etc/ssh/ssh_config (global configuration) or ~/.ssh/config (user specific file).
