usage : ./setup [options...]
--server address
Ip address of the machine running the re6stnet server. Both ipv4
and ipv6 addresses are supported.
--port port
Port to connect to on the machine running the re6stnet server.
-d, --dir directory
Path of a directory where will be stored the files generated by the
setup. The Setup genereates the following files, in the explicit
order :
- ca.pem : certificate authority file downloaded from the server
- peers.db : peers database initialized for
- cert.key : private key generated by the script
- cert.crt : individual certificate file generated by the server
- dh2048.pem : dh file for oenvpn server
-r, --req name value
Specify an attribute to add to the certificate request sent to the
server. Can be used multiple times.
Each use of the --req name value, will add the attribute name with
the associated value in the sugbject of the certificate request.
Stop the script after downloading the certificate authority file
from the server
Stop the script after creating the peers DB and downloading the
connection information of a bootstrap node of the VPN.
Does not re'quest a bootstrap peer to the peer discovery server
(useful in debug when the server does not have any peer in his
database). When requesting a bootstrap peer to a server whoch does
not have any, an execption will occur, and the script will stop
usage : ./registry port [options...]
The port on which the server will listen
--private ip
Ipv6 address of the re6stnet client running on the machine. This
address will be advertised only to nodes having a valid
--db path
Path to the server Database file. A new DB file will be created
and correctly initialized if the file doesn't exists.
One can give ":memory" as path, the database is then temporary
--ca path
Path to the certificate authority file. The certificate authority
MUST contain the VPN network prefix in its serial number. To
generate correct ca and key files for the 2001:db8:42:: prefix,
the following command can be used :
openssl req -nodes -new -x509 -key ca.key -set_serial \
0x120010db80042 -days 365 -out ca.crt
--key path
Path to the server key file. To generate a key file, see the --ca
--bootstrap prefix ip port proto
Connection informations of a node given to other as a bootstrap
node to initiate connection with the network.
Prefix should be the prefix number of a node, given in binary and
with correct length. For instance the VPN address
2001:db8:42:1::/64 ( asusming a network prefix 2001:db8:42::/48 )
corresponds to a prefix 1/16 i.e 0000000000000001.
--mailhost mailhost
Mailhost to be used to send email containing token for registration
usage : ./ [options...]
--ip address port proto
Specify connection information to be advertised to other nodes.
address MUST be a ipv4 address since as of now openvpn does not
support ipv6 addresses.
Proto should be either udp or tcp-client
-i, --interface interface
Give one interface name for each use of the argument. The interface
will be used to detect other nodes on the local network.
--peers-db-refresh duration
Duration in seconds of the peers DB refresh interval.
Default : 3600 ( 1 hour )
-l, --log directory
Path to the directory used for log files. Will create one file
for babel logging and one file for each openvpn server and client
Default : /var/log
-s, --state directory
Path to the directory used for state files. State files include :
- peers.db : the peers db used to establish connection
- re6stnet.babeld.state : babeld state file ( created if does not
exists, overriden if exists )
There must be a valid peers db file ( named peers.db ) in the
directory. A valid peers db file can be created with
Default : /var/lib/re6stnet
-v, --verbose level
Defines the verbose level, level should be an integer between 0
and 3 ( including ). There is no precise convention for verbode
level for now, except an increased number means more log messages.
This parameter is also given to babel for its log.
To adjust verbose level for openvpn, add an openvpn optional
arguments at the end of the command line
Default : 0
--registry address
Complete public ( reachable from the internet ) address of the machine
running a registry. Will be used to get the pirvate address of the
registry and/or bootstrap peers
Examples :, http://[2001:db8:42::1]:80
--hello duration
Set hello interval, in seconds, for both wired and wireless
connections. Openvpn ping-exit option is set to 4 times the hello
interval. Argument passed down to the babel daemon, equivalent
to :
-h duration -H duration
in babeld ( for more information, see babeld man page )
It takes between 3 times and 4 times the hello interval for babel
to re-establish connection with a node for which the direct
connection has been cut
Default : 15
-w, --wireless
Consider all interfaces as being wireless interfaces. Argument
directly passed down to the babeld daemon
--pp port proto
Port and protocol used by the openvpn server(s). Start one openvpn
server for each couple port/protocol specified.
Additionally, if no external configuration is given in the command
line, re6stnet will attempt to forward a port with upnp for each
couple port/proto given.
Protocols should be either udp or tcp-server.
Default : (1194, udp), (1194, tcp-server)
--tunnel-refresh duration
Interval in seconds between two tunnel refresh. Refreshing tunnels
mean :
- killing all dead tunnels ( detected via the ping-exit option
if openvpn )
- killing the 'worst' tunnels, so that at least the ratio of
tunnels set by the --refresh-rate option have been killed
- creating new tunnels to other clients randomly choosen in the
peers database, to reach the number of connection specified by
the connection-count option ( There can be less tunnels if the
peers DB does not contain enough peers )
Default : 300
--dh path
Path to the dh file to be used by the openvpn server
(for more information see the openvpn man page)
--ca path
Path to the certificate authority file delivered by the re6stnet
server. The prefix of the VPN network is included in the serial
number of the file.
--cert path
Path to the individual certificate file delivered by the re6stnet
server. The prefix of the machine is included in the certificate's
subject common name.
--connection-count number
The maximum number of openvpn clients to start.
Default : 20
--refresh-rate ratio
The ratio of connection to kill each time we refresh tunnels.
For more information see the --tunnel-refresh option
ratio should be a float between 0 and 1 ( included )
Default : 0.05
Additional arguments to be passed down to all openvpn processes
can be given at the end of the command line.
In that case, insert '--' to delimit re6stnet regular options
from the additional openvpn arguments. The list of arguments will
be passed down to ALL openvpn processes ( including servers )
exactly as they are given
One SHOULD give a --key argument with the key file delivered by the
re6stnet server
You can give to re6stnet a config file as a regular argument
(meaning before giving optional openvpn arguments)
The file should contain one option per line, possibly ommitting
the '--'. Only long option are allowed (i.e "v 3" will not work
while "verbose 3" will)
You can give a file ( with the @ prefix ) as an argument within a
