How to Ignore/disable SSH Host Key Verification

# SSH
ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no  sarav@mwinventory.in

# SCP
scp -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no somefile.txt sarav@mwinventory.in:/var/tmp/

ssh ignore host key verification

In your ~/.ssh/config (if this file doesn't exist, just create it):

Host *
    StrictHostKeyChecking no
    
Rather than adding it to your ~/.ssh/config file for all Host *, it would be a safer to specify a particular host.
You can also pass a parameter on the command-line like this:

ssh -o StrictHostKeyChecking=no yourHardenedHost.com
