TSPC.CONF(5)

NAME
tspc - tspc configuration file

SYNOPSIS
tspc.conf

DESCRIPTION
The tspc(8) is a client program which enables a host to query a tunnel server to establish a tunnel between the host and the server. The tspc configuration file contains information that is read by tspc(8) for specific information about the server and the tunnel to be established.

This file is designed to be human readable and may be edited by any text editor. The file consists of tokens and values, which are separated by the equal sign. Each "Token=Value" pair must be on their own line.

The different configuration options are:

tsp_dir
    The current directory where tspc programs and templates are located. This variable might look something like this:

    tsp_dir=/usr/local/tsp

    This variable is MANDATORY.

auth_method
    Authentication method: auth_method=any|digest-md5|anonymous|plain

    any is the preferred one. The most secure mechanism common to the client and the broker will be used.

    digest-md5 sends the username in clear, but not the password.

    plain sends both username and password in clear.

    anonymous sends no username and no password.

    Default: any

client_v4
    IPv4 address of the client tunnel endpoint. If the host has more than one IPv4 address, it is recommended to manually set this variable with its local IPv4 address as value. If set to auto, it chooses the source ip used when communicating with the server. This variable might look something like this:

    client_v4=a.b.c.d

    client_v4=auto

    Default: any

userid
    The userid is used for authentication to the server. By default tspc uses anonymous as the userid. The TSP protocol allows both anonymous and authenticated tunnel setup. Look at the server policies for supported modes and related services and for procedures to register your user name. The syntax is:

    userid=anonymous|user_name

    This variable is MANDATORY.

passwd
    passwd=your_password

    Leave empty if userid=anonymous

server
    Name and port number of the tunnel server. This variable is used to specify the TSP server to be queried. An IPv4 address or FQDN (Fully Qualify Domain Name) can be used. The port number is optional. Default TSP port is 3653.

    server=host[:port]

    server=broker.freenet6.net

    server=192.168.1.1:3653

    This variable is MANDATORY

template
    This parameter is used to tell which configuration template must be used to configure the tunnel. The configuration template is a script file, located in the template directory of the package, that contains the system commands to be executed for tunnel setup. The parameters are passed to the script file as environment variables. Normally the template parameter is set when the package is built for the specific operating system. Look in the template directory to see which ones are available. The template name must be the file name without the .sh or .bat suffix.

    template=linux

    This variable is MANDATORY.

retry_delay
    The retry_delay option is used to set the number of seconds to sleep before retrying tunnel request to tsp server after request failure. It will retry until success. Set it to 0 if you don't want to retry.

    Default: 30

tunnel_mode
    Tunnel encapsulation mode:

    tunnel_mode can take the following values

    "v6v4" request an IPv6 in IPv4 tunnel

    "v6udpv4" request an IPv6 in UDP in IPv4 tunnel (for clients behind a NAT) This type of tunnel is supported under Linux, FreeBSD and Windows.

    "v6anyv4" Let the broker choose the tunnel mode appropriate for my client with v6anyv4, the broker will discover if the client is behind a NAT or not and will offer to the TSP client the correct tunnel mode.

    Default: v6anyv4

if_tunnel_v6v4
    Logical interface name that will be used for the configured tunnel (IPv6 over IPv4). The syntax is:

    if_tunnel_v6v4=name

    Under *BSD: gif0

    Under Linux: sit0

    Under Windows: 2

    This variable is MANDATORY.

if_tunnel_v6udpv4
    Logical interface name that will be used for v6udpv4 tunnels (IPv6 over UDPv4). The syntax is:

    if_tunnel_v6udpv4=name

    Under FreeBSD: tun1

    Under Linux: tun

    Under Windows: tunv6

proxy_client
    proxy_client indicates that this client acts as a TSP proxy for some remote client tunnel endpoint machine. It is set to "yes" if the machine running the tsp client requests a tunnel for another machine. (e.g: cisco template). This must be used with a static IPv4 address in client_v4 variable.

    NOTE: proxy_client=yes is incompatible with tunnel_mode=v6udpv4

    Default: no

keepalive
    keepalive indicates that this client will send keepalives to keep the tunnel active and detect inactive tunnel (if no response from server). When a tunnel is detected inactive, the TSP client automatically reconnects to the server. keepalive_interval is a suggestion from the TSP client to the broker for the interval between two keepalive messages. The broker may impose a different interval value to the client if the interval value is too low.

    keepalive=yes

    Default: yes

keepalive_interval

    keepalive_interval=30

    Default: 30

host_type
    In order to configure the machine as a router, a prefix must be requested and an interface must be specified. The prefix will be advertised on that interface.

    host_type=host|router

    Default: host

prefixlen
    prefixlen specifies the required prefix length for the TSP client network. Valid values are 64 or 48. 64 is for one link. 48 is for a whole enterprise network (65K links).

    Default: 48

if_prefix
    if_prefix is the name of the OS interface that will be configured with the first /64 of the received prefix from the broker and the router advertisement daemon is started to advertise that prefix on the if_prefix interface.

dns_server
    This parameter is used to specify the DNS servers that should be used for reverse DNS delagation of the prefix allocated. Syntax is:

    dns_server=fqdn[:fqdn]...

    For example, to use ns1.nowhere.net and ns1.nowhere.net as authoritative NS servers for reverse DNS of the prefix, this line would be used in tspc.conf:

    dns_server=ns1.nowhere.net:ns2.nowhere.net

    Never use an IP address as a DNS server name.
