TincVPN

1) Install tinc on your Linux (e.g. apt-get install tinc) MAKE SURE YOU HAVE AT LEAST TINC 1.0.13

2) mkdir /etc/tinc/ninux

3) Create /etc/tinc/ninux/tinc.conf

Name = yournickname
ConnectTo = Norimberga
Mode = switch

Please pick a unique yournickname. Norimberga is our hub server. Mode switch is required because tinc will operate with a tap interface, needed to run olsr on it.

4) Create the hosts folder mkdir /etc/tinc/ninux/hosts/

5) Generate a Keypair tincd -n ninux -K

6) Create the file /etc/tinc/ninux/hosts/Norimberga

This file has the address and the public key of the server

Address = svn.ninux.org

-----BEGIN RSA PUBLIC KEY-----

If you want also a backup link use also our secondary server

6a) Create the file is /etc/tinc/ninux/hosts/guinness

Address = hispanico.ninux.org

6b) Modify the file /etc/tinc/ninux/tinc.conf

Name = yournickname
ConnectTo = Norimberga
ConnectTo = guinness
Mode = switch

7) Get an IP address in the subnet 10.0.1.0/24 and add your self in the table on this wiki page: GestioneIndirizzi

8) Create the file /etc/tinc/ninux/tinc-up

ip link set dev ninux up
ip a a dev ninux HEREYOURIPADDRESS/24 broadcast 10.0.1.255
#Adjust MTU
ip link set mtu 1350 dev ninux
iptables -A FORWARD -p tcp -m tcp --tcp-flags SYN,RST SYN -j TCPMSS --clamp-mss-to-pmtu

Where in place of HEREYOURIPADDRESS you must put the IP address choosen at point 7 of this guide

Make the file executable chmod +x /etc/tinc/ninux/tinc-up

9) Send an email to contatti@ninux.org with your Nickname choosen at point 3 and your generated public key so we can authorize you in the VPN main and backup server.

10) Once you received notification that your public key is authorized you can try to connect

tincd -n ninux

If everything worked out you can ping 10.0.1.1. Now configure olsr to use the interface "ninux"

Important notes on the OLSR configuration

It is FUNDAMENTAL to:

Use olsr version 0.6.1
Insert a Link Quality Multiplier in the interface part of the olsrd.conf file. On servers, it should looks like

Interface "ninux"
{
    LinkQualityMult default 0.2
}

on OpenWRT just look below.

**BEWARE:** if you use this configuration on a pc and you don't want to override the default gw you shoul use a LOWER metric for your prefered gw. This can be do using metric of your distro, on debian the default gw metric is 100 so lower it to 0 is a MUST.
