Update RubyGems 1.2 to 1.3.1 on Mac OS

Due to a nasty bug in RubyGems 1.2, you need to install a special gem to be able to update to version 1.3.1:

# sudo gem install rubygems-update
# sudo update_rubygems

Note: This will only work on UNIX hosts.

1. Create your private/public key pair, which will create a private key in ~/.ssh/id_rsa a public one in ~/.ssh/id_rsa.pub:
# ssh-keygen -t rsa

2. Now copy your public key over to the remote host:
# scp ~/.ssh/id_rsa.pub username@remote-host.com:~
# ssh username@remote-host.com
# cat ~/id_rsa.pub >> ~/.ssh/authorized_keys

3. You’re done! You can now access the remote host with the same SSH command like before, but won’t be prompted to enter a password anymore!
