NAME
ntkd - Netsukuku protocol daemon
SYNOPSIS
ntkd [-hvaldrD46] [-i net_interface] [-c conf_file] [-l logfile]
DESCRIPTION
Netsukuku is a mesh network or a P2P net system that generates and
sustains itself autonomously. It is designed to handle an unlimited
number of nodes with minimal CPU and memory resources. Thanks to this
feature it can be easily used to build a worldwide distributed,
anonymous and anarchical network, separated from the Internet, without
the support of any servers, ISPs or authority controls.
The complete features list of Netsukuku is here:
<http://netsukuku.freaknet.org/files/doc/misc/Ntk_features_list>
In order to join to Netsukuku you have to use ntkd, which is the daemon
implementing the Npv7 protocol. The daemon at startup takes the list of
all the network interfaces which are currently UP and it uses all of
them to send and receive packets. If you want to force the daemon to use
specific interfaces you should use the -i option. The ports it listens
to are: 269-udp, 269-tcp, 277-udp, 277-tcp. So be sure to open them in
the firewall.

OPTIONS
-4, --ipv4
Forces the daemon to use ipv4 addresses only
-6, --ipv6
Forces the daemon to use ipv6 addresses only. Warning, this is still
experimental.
-i *interface*, --iface *interface*
Specifies the network interface the daemon will use to join
Netsukuku, i.e. wlan0. You can use more than one interface by
specifying multiple times the -i option. For example:
ntkd -i wlan0 -i eth0 -i wifi1 -i eth1
-a, --no_andna
Forces ntkd to don't run the ANDNA daemon when started.
-R, --no_resolv
When NetsukukuD starts it modifies /etc/resolv.conf writing in the
first line the string "nameserver 127.0.0.1". The old
/etc/resolv.conf is copied in /etc/resolv.conf.bak. When the daemon
is closed /etc/resolv.conf is restored. If you want to disable this
set use the -R option.
-r*[bool]*, --restricted=*[bool]*
With this option the daemon will run in restricted mode as specified
in the Npv7, only IPs of a private class will be chosen. It is used
for Internet compatibility. If no argument is given to the option,
the default restricted private class 10.0.0.0 is used, otherwise if
*bool* is not zero, the restricted class will be
172.16.0.0-172.31.255.255.
-I, --share-inet
Tells NetsukukuD to run in restricted mode (see -r) and to share
your Internet connection. Please check the relative options in
/etc/netsukuku/netsukuku.conf
-D, --no_daemon
This option tells ntkd to don't detach to background and daemonizing
itself. The daemon will run on foreground instead.
-c *configuration_file*, --conf *configuration_file*
Specifies the name of the configuration file. The default is
/etc/netsukuku/netsukuku.conf. ntkd will not start without a
configuration file.
-l *logfile*, --logfile *logfile*
Specifies that ntkd should send all of its messages to the specified
file. The *logfile* will be overwritten.
-d, --debug
With this option the daemon will run with displaying its debug
messages. The more -d you specify the more debug messages you'll
get. Sometimes it's cool to use it, but be careful and don't go
insane ;)
-h, --help
Display a the list of available options and their brief description.
-v, --version
Displays the version of the ntkd daemon.
EXAMPLES
Usually you'll just want to use ntkd with a wifi device:
ntk-wifi wlan0
ntkd -i wlan0
If you one to use more than one network interface:
ntkd -i eth0 -i wlan0 -i wifi1 -i eth2
SIGNALS
When the SIGHUP signal is sent to ntkd(8), the andna_hostnames and
snsd_nodes files will be reloaded and it will try to register all the
new added hostnames and snsd records.
When the SIGALRM signal is sent to ntkd, the resolved hostnames cache is
flushed.
LOGS
If ntkd is started as a daemon (without the -D option), all the logs are
sent to syslog under the LOG_DAEMON category.
If the no-daemon option (-D) is used, all the logs are printed to
stderr.
FILES
/etc/netsukuku/netsukuku.conf
It is the default path for the ntkd configuration file. It's
possible to choose another file using the -c option.
/etc/netsukuku/andna_hostnames
It is the file where the hostnames to be registerd in ANDNA are kept
one per line. It's location can be changed by modifying the relative
option in the netsukuku.conf file.
/etc/netsukuku/snsd_nodes
The snsd_nodes_file keeps the list of the SNSD records which will be
register in ANDNA.
/usr/share/netsukuku/ext_map_file
/usr/share/netsukuku/int_map_file
/usr/share/netsukuku/bnode_map_file
They are the Netsukuku maps saved by the daemon. Their locations can
be changed in netsukuku.conf.
/usr/share/netsukuku/andna_lcl_keyring
In this keyring your ANDNA public and secret keys are saved. Handle
this file with care: without it, you won't be able to update your
hostnames, thus you'll definitely lose them.
/usr/share/netsukuku/andna_cache
/usr/share/netsukuku/andna_lcl_cache
/usr/share/netsukuku/andna_rh_cache
/usr/share/netsukuku/andna_counter_cache
They are the saved ANDNA caches. Their locations can be changed in
netsukuku.conf.
/etc/netsukuku/ip_masquerade.sh
This script is launched by NetsukukuD, at its start, when it shares
the Internet connection. The script will activate the IP
masquerading. The script is also used to disable the IP masquerading
when ntkd is closed.
/etc/netsukuku/tc_shaper.sh
This script manages the traffic shaping for the upload bandwidth. It
is executed by ntkd at its start if its relative option has been
enabled.
/var/run/ntkd.pid
It is the lock file created by ntkd at its start, it is used to
check if other instances of ntkd are already running. Only one
instance is allowed.

If you are using modules you have to load them before launching the
daemon.
