Access restriction to this web service can be done in file "lgproxy.cfg". Two access restriction methods can be configured:

Installation
|
||||
------------
|
||||
|
||||
The web service (lg.py) depends on:
|
||||
|
||||
- python-flask >= 0.8
|
||||
- python-dnspython
|
||||
- python-pydot
|
||||
- python-memcache
|
||||
- graphviz
|
||||
- whois
|
||||
- traceroute
|
||||
|
||||
Each services can be embedded in any webserver by following regular python-flask configuration.
|
||||
The proxy running on routers (lgproxy.py) depends on:
|
||||
|
||||
- python-flask >= 0.8
|
||||
- traceroute
|
||||
- ping
|
||||
|
||||
Each service can be embedded in any webserver by following regular python-flask configuration.
|
||||
It is also possible to run the services directly with python for developping / testing:
|
||||
|
||||
python2 lg.py
|
||||
python2 lgproxy.py
|
||||
|
||||
Systemd unit files are provided in the `init/` subdirectory.
|
||||
|
||||
|
||||
Configuration
|
||||
-------------
|
||||
|
||||
On your routers, copy `lgproxy.cfg.example` to `lgproxy.cfg` and edit the values.
|
||||
|
||||
On the web host, copy `lg.cfg.example` to `lg.cfg` and edit the values.
