mmeettiiss..ccffgg (5) File Formats Manual mmeettiiss..ccffgg (5)
NNAAMMEE
mmeettiiss..ccffgg -- mmeettiiss..ccffgg is an example of a configuation file
usable with mmeettiiss__ddaaeemmoonn((11)), though there is nothing special about the
actual filename. Each line of the configuration file is also usable
with mmeettiiss__ccoonnttrrooll((11)). This document specifies all available command
lines used to configure and query Metis.
All commands have a 'help', so typing 'help command' will display on-
line help.
In a configuration file, lines beginning with '#' are comments.
AADDDD CCOOMMMMAANNDDSS
add connection ether _s_y_m_b_o_l_i_c _d_m_a_c _i_n_t_e_r_f_a_c_e
Adds an Ethernet connection on _i_n_t_e_r_f_a_c_e to the given desti-
nation MAC address. The _s_y_m_b_o_l_i_c name is a symbolic name for
the connection, which may be used in later commands, such as
aadddd rroouuttee. There must be an Ethernet Listener on the speci-
fied interface (see aadddd lliisstteenneerr), and the connection will
use the same EtherType as the Listener. The _d_m_a_c destination
MAC address is in hexidecimal with optional "-" or ":" sepa-
rators.
A connection is a target for a later route assignment or for
use as an ingress identifier in the PIT. When using a broad-
cast or group address for a connection, an Interest routed
over that connection will be broadcast. Many receivers may
respond. When Metis receives a broadcast Interest it uses
the unicast source MAC for the reverse route -- it will auto-
matically create a new connection for the source node and put
that in the PIT entry, so a Content Object answering the
broadcast Interest will only be unicast to the previous hop.
add connection ether conn7 e8-06-88-cd-28-de em3
add connection ether bcast0 FFFFFFFFFFFF eth0
add connection (tcp|udp) _s_y_m_b_o_l_i_c _r_e_m_o_t_e___i_p _r_e_m_o_t_e___p_o_r_t _l_o_c_a_l___i_p
_l_o_c_a_l___p_o_r_t
Opens a connection to the specific _r_e_m_o_t_e___i_p (which may be a
hostname, though you do not have control over IPv4 or IPv6 in
this case) on _r_e_m_o_t_e___p_o_r_t. The local endpoint is given by
_l_o_c_a_l___i_p _l_o_c_a_l___p_o_r_t. While the _l_o_c_a_l___i_p _l_o_c_a_l___p_o_r_t are tech-
nically optional parameters, the system's choice of local
address may not be what one expects or may be a different
protocols (4 or 6). The default port is 9695.
A TCP connection will go through a TCP connection establish-
ment and will not register as UP until the remote side
accepts. If one side goes down, the TCP connection will not
auto-restart if it becomes availble again.
A UDP connection will start in the UP state and will not go
DOWN unless there is a serious network error.
Opens a connection to 1.1.1.1 on port 1200 from the local
address 2.2.2.2 port 1300
add connection tcp conn0 1.1.1.1 1200 2.2.2.2 1300
opens connection to IPv6 address on port 1300
add connection udp barney2
fe80::aa20:66ff:fe00:314a 1300
add listener (tcp|udp) _s_y_m_b_o_l_i_c _i_p___a_d_d_r_e_s_s _p_o_r_t
add listener ether _s_y_m_b_o_l_i_c _i_n_t_e_r_f_a_c_e_N_a_m_e _e_t_h_e_r_t_y_p_e
add listener local _s_y_m_b_o_l_i_c _p_a_t_h
Adds a protocol listener to accept packets of a given proto-
col (TCP or UDP or Ethernet). The _s_y_m_b_o_l_i_c name represents
the listener and will be used in future commands such as
access list restrictions. If using a configuration file on
mmeettiiss__ddaaeemmoonn, you must include a listener on localhost for
local applications to use.
The _i_p___a_d_d_r_e_s_s is the IPv4 or IPv6 local address to bind to.
The _p_o_r_t is the TCP or UDP port to bind to.
The _i_n_t_e_r_f_a_c_e_N_a_m_e is the interface to open a raw socket on
(e.g. "eth0"). The _e_t_h_e_r_t_y_p_e is the EtherType to use, repre-
sented as a 0x hex number (e.g. 0x0801) or an integer (e.g.
2049).
The _p_a_t_h parameter specifies the file path to a unix domain
socket. Metis will create this file and remove it when it
exits.
Listens to 192.168.1.7 on tcp port 9695 with a symbolic name
'homenet'
add listener tcp homenet 192.168.1.7 9695
Listens to IPv6 localhost on udp port 9695
add listener udp localhost6 ::1 9695
Listens to interface 'en0' on ethertype 0x0801
add listener ether nic0 en0 0x0801
add route _s_y_m_b_o_l_i_c _p_r_e_f_i_x _p_r_e_f_i_x
Adds a static route to a given _p_r_e_f_i_x to the FIB for longest
match.
Currently, the _s_y_m_b_o_l_i_c and _c_o_s_t are not used.
LLIISSTT CCOOMMMMAANNDDSS
list connections
Enumerates the current connections to Metis. These include
all TCP, UDP, Unix Domain, and Ethernet peers. Each connec-
tion has an connection ID (connid) and a state (UP or DOWN)
followed by the local (to metis) and remote addresses.
list interfaces
Enumerates the system interfaces available to Metis. Each
interface has an Interface ID, a 'name' (e.g. 'eth0'), an MTU
as reported by the system, and one or more addresses.
list routes
Enumerates the routes installed in the FIB. The _i_f_a_c_e is the
out-bound connection. The _p_r_o_t_o_c_o_l is the the routing proto-
col that injected the route. _r_o_u_t_e is the route type.
'LONGEST' means longest matching prefix and 'EXACT' means
exact match. Only 'LONGEST' is supported. _c_o_s_t is the cost
of the route. It is not used. _n_e_x_t is the nexthop on a mul-
tiple access interface. it is not used because the current
implementation uses one connection (iface) per neighbor.
_p_r_e_f_i_x is the CCNx name prefix for the route.
