     tspc - tspc configuration file




     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:

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


       This variable is MANDATORY.

       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

       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:



       Default: any

       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:


       This variable is MANDATORY.


       Leave empty if userid=anonymous

       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.



       This variable is MANDATORY

       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.


       This variable is MANDATORY.

       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 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

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


       Under *BSD: gif0

       Under Linux: sit0

       Under Windows: 2

       This variable is MANDATORY.

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


       Under FreeBSD: tun1

       Under Linux: tun

       Under Windows: tunv6

       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 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.


       Default: yes



       Default: 30

       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.


       Default: host

       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 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.

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


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

       Never use an IP address as a DNS server name.
