SSH passwordless logins

Paswordless SSH logins

# Create the .ssh directory if it's not already under ~/
ssh user@server
mkdir .ssh
chmod 700 .ssh
exit

# Create a private/public key pair if you didn't already
ssh-keygen

# Copy your public key to the remote server
cat .ssh/id_rsa.pub | ssh user@server "cat >> .ssh/authorized_keys"

# You should now be able to login without a password prompt
ssh user@server

# If not, check the permissions again of ~/.ssh and ~/.ssh/authorized_keys
# Both should be set to 700 (rwx only by user)

# If it's still not working, check the permissions of your home directory (/home/user)
# It should be set to 755 (drwxr-xr-x)

# If for some reason you see a capital S in the permissions, chmod g-s should remove it
