       ssh magic + your commandline edc (Everyday carry)
       =================================================
       
       Securely load your custom bash functions automatically on every
       ssh connect.
       
       Most of us know this situation: You connect to a new server and
       sooner or later miss an alias or shell function that you use on
       your personal system.
       
       In the following i'll explain how you can securely load your list
       of bash-functions.
       
       This example involves three computers:
       
         a) your local machine
            - running ssh-agent
            - in ~/.ssh/config set:
       
                ForwardAgent yes
                RequestTTY yes
                RemoteCommand bash --rcfile <(cat .bashrc 2> /dev/null; git archive --remote=ssh://src@kroovy.de:/path/to/repo HEAD toolbox.sh | tar -xO)
 (TXT) raw
       
       
         b) the server you connect to
            - in /etc/ssh/sshd_config set:
       
                AllowAgentForwarding yes
       
       
         c) your git server that allows auth via ssh-key
            - deposit your local machine's pubkey 
       
       
       
       Authentication
       --------------
       We serve git via SSH. This enables us to have authentication via
       your SSH-Key.
       We use the command `git archive` to grab just one file from the
       repository.
       
       
       
       Notes:
       ------
       If you want to harden the setup, you can can include a sha256sum
       check within your local machine's config:
       
                RemoteCommand t=$(mktemp); git archive --remote=ssh://src@kroovy.de:/path/to/repo HEAD toolbox.sh | tar -xO | tee $t | sha256sum | awk '{print $1}' | cmp -s <(echo "86dd63a2159898efeddc56e94232291f5412edf0e6e0fb0d862c81f03f5feff5") || exit; bash --rcfile <(cat .bashrc 2> /dev/null; cat $t); rm $t
