./script 192.168.1.118) and add the fingerprint to~/.ssh/known_hostsbefore it then moves to the next line — thereby avoiding the missing SSH fingerprint issue. Of course the above would only work properly if you have ssh key authentication setup. Otherwise, you’d have to enter...
When you run your script, it may get foiled by an issue where it is stopped by a server that has yet to have its SSH key fingerprint added to the known_hosts file. When this happens, your script is rendered useless. SSH key fingerprint What is an SSH key fingerprint? Simple: It is ...
When managing many hosts, answering 100s of “yes” can make us crazy. In a trusted environment, let ssh automatically add the new hosts to the list of known hosts and free us from typing “yes”es. How to enable it? Method 1. Passing option to ssh ssh -o StrictHostKeyChecking=no ...

ssh-keyscan is a very useful tool to collect the available public keys of multiple numbers of hosts. The main purpose of this tool is to verify the known_hosts files. The non-blocking socket I/O is used by this tool to connect with the maximum number of hosts in parallel. The key ...
It is also possible that the RSA host key has just been changed. The fingerprint for the RSA key sent by the remote host is 3f:1b:f4:bd:c5:aa:c1:1f:bf:4e:2e:cf:53:fa:d8:59. Please contact your system administrator. Add correct host key in /home/admin/.ssh/known_hosts to get...

Saying "yes" adds a key entry to your ".sshknown_hosts" file. The next time you connect ssh will check that key and will either silently connect or give you a scary message if the key doesn't match. [A key mismatch can happen if you reinstall the remote system and it still has th...
remote servers you've connected to previously. When you connect to a server, SSH checks its host key against the one stored in your known_hosts file. If they match, it confirms the server's identity. If not, SSH warns you about a potential security risk, preventing man-in-the-middle ...
