When no peer is avalaible, the setup crash without the --no-boot option
G : see below
U : this is still a bug to be solved
G : since the server is now a node it shouldn't ( the server will always
have a peer availabel which is himself )
To be done :
Use an algorithm to choose which connections to keep and/or establish
instead of pure randomness
Find a name for the project : the projet is ( or should be ) independant
from vifib, openvpn, babel, and so should the name; btw we aim to build a
distributed, scalable, resilient VPN.... ( if it helps with the name )
Replace comments at the beginning of functions with docstrings & give all
fn docstrings
Use the server events ( client connection/deconnection ) to do something
useful
In peers DB, remove some peers when they are too many of them -> remove the
dead peers
Use a timeout for the peersDB
Use a timeout for the peersDB
G : removing the dead peers should be enough
U : I was speaking of the server peers DB
G : the timeout is the duration of the certificate delivered ( 1y for now )
Specify a lease duration in ForwardViaUPnP
Handle LAN internally in order not to have catastrophic results ....

30 sec of hello interval seams also too much. The default value for
babel is 4 sec (from babel man page).
