# FreifunkManager [![Build Status](https://travis-ci.org/FreifunkBremen/freifunkmanager.svg?branch=master)](https://travis-ci.org/FreifunkBremen/freifunkmanager) [![Coverage Status](https://coveralls.io/repos/github/FreifunkBremen/freifunkmanager/badge.svg?branch=master)](https://coveralls.io/github/FreifunkBremen/freifunkmanager?branch=master)
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](https://github.com/FreifunkBremen/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).
