SSH Config File

If You’re connecting to remote server over SSH on A daily basis, you might discover that recalling all the remote IP addresses, different usernames, non-standard ports, and various command-line options is difficult, maybe impossible.

The options are read by the OpenSSH client Setup file (~/.ssh/ / config). You can save SSH choices that are different for every machine you link to.

There is A sample SSH config shown below:

Host dev

HostName dev.linuxize.com

User mike

Port 4422


By typing the control is deved by ssh, After you invoke the ssh client Will see the ~/.ssh/config file and apply. In this case, ssh dev is equal to these:

Public Key Authentication

Authentication mechanisms are supported by the SSH protocol.

The authentication mechanism lets you Log into the server.

This technique works by creating a set of keys The private key is saved on the client device, along with the key is moved you would like to log into. The machine must be configured to take authentication that was key.

If you do not have SSH key pair in your machine

You’ll be asked to form a passphrase that is secure. Whether you Wish to use passphrase.

Copy the public key As Soon as You have your key group

ssh-copy-id username@hostname

Input the key will be, and the user password Appended to the user authorized_keys file.

You can log into the distant When the secret is uploaded Without being prompted for a password server.

By placing a key-based authentication, you are able to simplify the Login procedure and boost the server safety.

Port Forwarding

SSH port forwarding or SSH tunneling is a method of generating An SSH link between a client and a host machine through uninstalled.

SSH forwarding is Helpful for transporting network information of Services which use an protocol, such as FTP or even VNC, bypassing intermediate or obtaining articles that is geo-restricted firewalls. You are able to TCP tunnel and port the traffic over a SSH connection.

Local Port Forwarding

Port forwarding allows you In the client host then and to the SSH server host to the destination server interface.

To make a port forwarding pass the -L option

ssh -L And -N to not execute a control.

Remote Port Forwarding

Port forwarding is the reverse of port forwarding. A interface is forwarded by it in the host host then and to the client host to the destination server interface.

Dynamic Port Forwarding

Dynamic port forwarding generates a SOCKS proxy host which Enables communication.

Dynamic port forwarding generates a SOCKS proxy server that Allows communication across a selection of ports.
