You can also get help with questions, comments, or trouble, by using
the CORE mailing lists:
* [core-users](https://pf.itd.nrl.navy.mil/mailman/listinfo/core-users) for general comments and questions
* [core-dev](https://pf.itd.nrl.navy.mil/mailman/listinfo/core-dev) for bugs, compile errors, and other development issues
## Building CORE
```shell
./bootstrap.sh
./configure
make
sudo make install
```
Building Documentation
----------------------
```shell
./bootstrap.sh
./configure
make doc
```
Building Packages
-----------------
Install fpm: http://fpm.readthedocs.io/en/latest/installing.html
Build package commands, DESTDIR is used for gui packaging only
```shell
./bootstrap.sh
./configure
make
mkdir /tmp/core-gui
make fpm DESTDIR=/tmp/core-gui
```
This will produce:
* CORE GUI rpm/deb files
* core-gui_$VERSION_$ARCH
* CORE ns3 rpm/deb files
* python-core-ns3_$VERSION_$ARCH
* CORE python rpm/deb files for SysV and systemd service types
* python-core-sysv_$VERSION_$ARCH
* python-core-systemd_$VERSION_$ARCH
Running CORE
------------
First start the CORE services:
```shell
# sysv
sudo service core-daemon start
# systemd
sudo systemctl start core-daemon
```
This automatically runs the core-daemon program.
Assuming the GUI is in your PATH, run the CORE GUI by typing the following:
```shell
core-gui
```
This launches the CORE GUI. You do not need to run the GUI as root.

# OLSR.org routing daemon config file
# This file contains the usual options for an ETX based
# stationary network without fisheye
# (for other options see olsrd.conf.default.full)
#
# Lines starting with a # are discarded
#
#### ATTENTION for IPv6 users ####
# Because of limitations in the parser IPv6 addresses must NOT
# begin with a ":", so please add a "0" as a prefix.
###########################
### Basic configuration ###
###########################
# keep this settings at the beginning of your first configuration file
# Debug level (0-9)
# If set to 0 the daemon runs in the background, unless "NoFork" is set to true
# (Default is 1)
# DebugLevel 1
# IP version to use (4 or 6)
# (Default is 4)
# IpVersion 4
#################################
### OLSRd agent configuration ###
#################################
# this parameters control the settings of the routing agent which are not
# related to the OLSR protocol and it's extensions
# FIBMetric controls the metric value of the host-routes OLSRd sets.
# - "flat" means that the metric value is always 2. This is the preferred value
# because it helps the linux kernel routing to clean up older routes
# - "correct" use the hopcount as the metric value.
# - "approx" use the hopcount as the metric value too, but does only update the
# hopcount if the nexthop changes too
# (Default is "flat")
# FIBMetric "flat"
#######################################
### Linux specific OLSRd extensions ###
#######################################
# these parameters are only working on linux at the moment
# SrcIpRoutes tells OLSRd to set the Src flag of host routes to the originator-ip
# of the node. In addition to this an additional localhost device is created
# to make sure the returning traffic can be received.
# (Default is "no")
# SrcIpRoutes no
# Specify the proto tag to be used for routes olsr inserts into kernel
# currently only implemented for linux
# valid values under linux are 1 .. 254
# 1 gets remapped by olsrd to 0 UNSPECIFIED (1 is reserved for ICMP redirects)
# 2 KERNEL routes (not very wise to use)
# 3 BOOT (should in fact not be used by routing daemons)
# 4 STATIC
# 8 .. 15 various routing daemons (gated, zebra, bird, & co)
# (defaults to 0 which gets replaced by an OS-specific default value
# under linux 3 (BOOT) (for backward compatibility)
# RtProto 0
# Activates (in IPv6 mode) the automatic use of NIIT
# (see README-Olsr-Extensions)
# (default is "yes")
# UseNiit yes
# Activates the smartgateway ipip tunnel feature.
# See README-Olsr-Extensions for a description of smartgateways.
# (default is "no")
# SmartGateway no
# Signals that the server tunnel must always be removed on shutdown,
# irrespective of the interface up/down state during startup.
# (default is "no")
# SmartGatewayAlwaysRemoveServerTunnel no
# Determines the maximum number of gateways that can be in use at any given
# time. This setting is used to mitigate the effects of breaking connections
# (due to the selection of a new gateway) on a dynamic network.
# (default is 1)
# SmartGatewayUseCount 1
# Determines the take-down percentage for a non-current smart gateway tunnel.
# If the cost of the current smart gateway tunnel is less than this percentage
# of the cost of the non-current smart gateway tunnel, then the non-current smart
# gateway tunnel is taken down because it is then presumed to be 'too expensive'.
# This setting is only relevant when SmartGatewayUseCount is larger than 1;
# a value of 0 will result in the tunnels not being taken down proactively.
# (default is 0)
# SmartGatewayTakeDownPercentage 0
# Determines the policy routing script that is executed during startup and
# shutdown of olsrd. The script is only executed when SmartGatewayUseCount
# is set to a value larger than 1. The script must setup policy routing
# rules such that multi-gateway mode works. A sample script is included.
# (default is not set)
# SmartGatewayPolicyRoutingScript ""
# Determines the egress interfaces that are part of the multi-gateway setup and
# therefore only relevant when SmartGatewayUseCount is larger than 1 (in which
# case it must be explicitly set).
# (default is not set)
# SmartGatewayEgressInterfaces ""
# Determines the routing tables offset for multi-gateway policy routing tables
# See the policy routing script for an explanation.
# (default is 90)
# SmartGatewayTablesOffset 90
# Determines the policy routing rules offset for multi-gateway policy routing
# rules. See the policy routing script for an explanation.
# (default is 0, which indicates that the rules and tables should be aligned and
# puts this value at SmartGatewayTablesOffset - # egress interfaces -
# # olsr interfaces)

### Example plugin configurations ###
#####################################
# Olsrd plugins to load
# This must be the absolute path to the file
# or the loader will use the following scheme:
# - Try the paths in the LD_LIBRARY_PATH
# environment variable.
# - The list of libraries cached in /etc/ld.so.cache
# - /lib, followed by /usr/lib
#
# the examples in this list are for linux, so check if the plugin is
# available if you use windows.
# each plugin should have a README file in it's lib subfolder
# LoadPlugin "olsrd_txtinfo.dll"
#LoadPlugin "olsrd_txtinfo.so.0.1"
#{
# the default port is 2006 but you can change it like this:
#PlParam "port" "8080"
# You can set a "accept" single address to allow to connect to
# txtinfo. If no address is specified, then localhost (127.0.0.1)
# is allowed by default. txtinfo will only use the first "accept"
# parameter specified and will ignore the rest.
# to allow a specific host:
#PlParam "accept" "172.29.44.23"
# if you set it to 0.0.0.0, it will accept all connections
#PlParam "accept" "0.0.0.0"
#}
#############################################
### OLSRD default interface configuration ###
#############################################
# the default interface section can have the same values as the following
# interface configuration. It will allow you so set common options for all
# interfaces.
InterfaceDefaults {
Ip4Broadcast 255.255.255.255
}
######################################
### OLSRd Interfaces configuration ###
######################################
# multiple interfaces can be specified for a single configuration block
# multiple configuration blocks can be specified
# WARNING, don't forget to insert your interface names here !
#Interface "<OLSRd-Interface1>" "<OLSRd-Interface2>"
#{
# Interface Mode is used to prevent unnecessary
# packet forwarding on switched ethernet interfaces
# valid Modes are "mesh" and "ether"
# (default is "mesh")
# Mode "mesh"
