# ssh setup

# The host you can ssh TO (your destinaton) is the 'server'

# The permissions need to be correct on  ~/   ~/.ssh  and ~/.ssh/authorized_keys
# Permissions for ssh files:
chmod  go -w ~/
chmod 700 ~/.ssh
chmod 600 ~/.ssh/authorized_keys

# The ssh key needs to be created on the client (your local machine, your home directory, etc).
# The "key" part remains on the client.
# The "public" part needs to be copied into ~/.ssh/authorized_keys on the server

# When generating keys, the key type you create depends on the command
# you use to generate the key:
#  -t option is "type" of key:  rsa, dsa, ecdsa
ssh-keygen -t ecdsa
