FreifunkManager

is a little software to manage gluon nodes with the help of ssh and yanic (used on the Breminale since 2017)

Preparations for Building

Install Go 1.10 or newer:

mkdir -p ~/inst
cd ~/inst
wget https://dl.google.com/go/go1.10.3.linux-amd64.tar.gz
tar xf go1.10.3.linux-amd64.tar.gz
export PATH=~/inst/go/bin/:$PATH
export GOROOT=~/inst/go/

Set $GOPATH:

export GOPATH=$HOME/go

Install nodejs >= 4.8:

mkdir -p ~/inst
cd ~/inst
wget https://nodejs.org/dist/v8.11.3/node-v8.11.3-linux-x64.tar.xz
tar xf node-v8.11.3-linux-x64.tar.xz
export PATH=~/inst/node-v8.11.3-linux-x64/bin/:$PATH

Install yarn (https://yarnpkg.com/en/docs/install):

mkdir -p ~/inst
cd ~/inst
wget https://github.com/yarnpkg/yarn/releases/download/v1.7.0/yarn-v1.7.0.tar.gz
tar xf yarn-v1.7.0.tar.gz
export PATH=~/inst/yarn-v1.7.0/bin/:$PATH

Building & Running

Download and build freifunkmanager:

go get -t github.com/FreifunkBremen/freifunkmanager/...
go get github.com/mattn/goveralls
go get golang.org/x/tools/cmd/cover
cd $GOPATH/src/github.com/FreifunkBremen/freifunkmanager/
go build
cd webroot
yarn install
yarn gulp build

Run:

./freifunkmanager -config config_example.conf

Usage

Visit http://localhost:8080/

Navigation bar at top of page:

• marker icon: (TODO)
• List: show list of all known nodes
  • use Edit link in last column of a node to edit its details; changes made on the Edit page are saved immediately
  • to change just the hostname, double-click on hostname field in list and make your change
• Map: show map of nodes
  • use Layers icon in upper right corner to enable geojson overlay and view clients
• Statistics: show statistics about nodes, clients, used channels...
• Login with text field: enter password (value of "secret" in config file) and click "Login" to log in
  • this is necessary to make any changes
  • there is no user management; anybody who has the password has full access
• blue rectangle on the far right: (TODO: connection status?)

Technical Details

List of known access points will be retrieved from Yanic (ie. representing live data from APs). Additionally, APs can be added manually by visiting a page like /#/n/apname (where "apname" is the node-id of the new AP), and then setting a hostname.

Each browser tab has a websocket connection to the server, so changes made in one tab will appear immediately in other tabs as well

All changes are saved to state file (eg. /tmp/freifunkmanager.json - can be changed in config file).
