OSX ssh-copy-id

In the case you're using OSX and you would like to use the ssh-copy-id command in order to import your SSH key to a server (which avoid the server to ask your user password), then you can install it really quickly thanks to Homebrew:

$ brew install ssh-copy-id

Then just do something like the following:

$ ssh-copy-id -i ~/.ssh/id_rsa.pub zedtux@zedroot.org
ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys

Number of key(s) added:        1

Now try logging into the machine, with:   "ssh 'guillaumeh@192.168.97.101'"
and check to make sure that only the key(s) you wanted were added.
