we do? Let's simulate this behavior! You are quite impressed!
Example: After the simulation server is re-installed, assuming that the server uses the same IP address, the public key of the server with the same IP address is different, what are the problems and solutions?
A: Use the method described in the previous section to delete the original public key and restart

Preparatory workSuppose a host 10.20.0.1 wants to log on to the B host 10.20.0.2 via SSH.Then the client (a host) needs to install the SSH client software, the server side (b host boot sshd process) needs to install the SSH se

Configuring SSH
Before installing SSH on this machine, you can install it via sudo apt-get install SSH or via new. If it is not configured, logging on to the local computer or the remote host requires a password for that host. Below is a password-free login configuration:
Very simple, execute
receives the request, first look for your public key in the user root directory of the server and compare it to the public key you sent over. If two keys are identical, the server encrypts the "Challenge" (challenge) with the public key and sends it to the client software. Thus avoiding being "man-in-the-middle" attacks.
On the server side,
The first step is to generate a public/private key pair
Using the SECURECRT tool-> create the public key, the cryptographic algorithm chooses RSA because the RSA algorithm is selected in the sshd configuration file
This step generates two files, the default is identity and Identity.pub, where identity is the key and Identity.pub is the public
