ssh disable warning messages – Linux/Ubuntu

To disable ssh warning message we need to add LogLevel to quiet in $HOME/.ssh/config file.

LogLevel=quiet

We can also diable warning messages with ssh command as shown below:

$ ssh -o LogLevel=quiet 192.168.1.10

With following example we can also disable Host Key Checking, set known hosts file to null and disable logging:

$ ssh -o UserKnownHostsFile=/dev/null -o StrictHostKeyChecking=no -o LogLevel=quiet 192.168.1.20
