##Git

Create an passwordless shh-key: ~/.ssh/github_vollhorst_rsa

 # $ ssh-keygen -t rsa -b 4096

Add the public key to the Vollhorst User on GitHub ssh keys, named after your Gateway

Vollhorst is in the AutoCRON Group, members are allowed to push here.

~/.ssh/config

#  Host github_vollhorst
#    User git
#    Hostname github.com
#    PreferredAuthentications publickey
#    IdentityFile ~/.ssh/github_vollhorst_rsa

test key-connection with github

# $ ssh github_vollhorst
# Hi Vollhorst! You've successfully authenticated, but GitHub does not provide shell access.
# Connection to github.com closed.

clone keys repository

# $ git clone ssh://github_vollhorst/Freifunk-Mainz/gluon-ffmz-keys /etc/fastd/mainzVPN/peers

##Sync

~/bin/autoupdate_fastd_keys.sh

# #!/bin/bash
# # Simple script to update fastd peers from git upstream
# # and only send HUP to fastd when changes happend.
#
# # SET YOUR GATEWAY NAME HERE
# GW_NAME="awesome gateway"
#
# # CONFIGURE THIS TO YOUR PEER DIRECTORY
# FASTD_PEERS=/etc/fastd/mainz_meshVPN/peers
#
# function getCurrentVersion() {
#  # Get hash from latest revision
#  git log --format=format:%H -1
# }
#
# function getDate() {
#  # Get timestamp
#  date "+%s"
# }
#
# cd $FASTD_PEERS
#
# # Get current version hash
# GIT_REVISION=$(getCurrentVersion)
#
# # Automagically commit local changes
# # This preserves local changes
# git commit -m "CRON $GW_NAME: auto commit $(getDate)"
#
# # Pull latest changes from upstream
# git fetch
# git merge origin/master -m "CRON $GW_NAME: auto merge $(getDate)"
#
# # Get new version hash
# GIT_NEW_REVISION=$(getCurrentVersion)
#
# if [ $GIT_REVISION != $GIT_NEW_REVISION ]
# then
#  # Version has changed we need to update
#  echo "Reload fastd peers"
#  kill -HUP $(pidof fastd)
#  git push -u origin master
# fi

finally

# $ chmod +x `~/bin/autoupdate_fastd_keys.sh`

crontab

# */20 * * * * $HOME/bin/autoupdate_fastd_keys.sh >> /var/log/fastd/autoupdate_fastd_keys.cron 2>&1

##Usage

to upload keys (and therefore sync to the other gateways) from /etc/fastd/mainzVPN/peers/ just add them:

# $ git add freifunk-000011112222

cron will come around to commit and push them

you may still commit and push manually

to delete keys (and therefore delete via sync from the other gateways) you have to delete them from git:

# $ git rm freifunk-000011112222

if you just remove them with rm freifunk-000011112222 they will come back when cron comes around again
