Interesting... What is xip.io? xip.io is a magic domain name that provides wildcard DNS for any IP address. Say your LAN IP address is 10.0.0.1 . Using xip.io, 10.0.0.1 .xip.io resolves to 10.0.0.1 www. 10.0.0.1 .xip.io resolves to 10.0.0.1 mysite. 10.0.0.1 .xip.io resolves to 10.0.0.1 foo.bar. 10.0.0.1 .xip.io resolves to 10.0.0.1 ...and so on. You can use these domains to access virtual hosts on your development web server from devices on your local network, like iPads, iPhones, and other computers. No configuration required! Think about what can it do for you?

When ssh to some AWS EC2 AMI such as RedHat , Amazon Linux and Ubuntu, ssh will prompt some message like below: Please login as the user "ec2-user" rather than the user "root". The secret is here: # cat /root/.ssh/authorized_keys no-port-forwarding,no-agent-forwarding,no-X11-forwarding,command="echo 'Please login as the user \"ec2-user\" rather than the user \"root\".';echo;sleep 10" Summary: You can define user-specific sshd config in ~/.ssh/authorized_keys file
