       vtund.conf - VTun(Virtual Tunnel) daemon configuration file.


       Configuration file for vtund(8) virtual tunnel daemon.

       File consists of sections in the form:

              name {
                keyword value;
                keyword value;

       Semicolon at the end of each keyword-value pair is required, as well as
       grouping curly braces {}.  Lines which begin with  ’#’  characters  are

       Name of section (name) can be one of:

              this section specifies general options for vtund

              specifies default options for all sessions

              (any  other  word except "options" and "default") introduces new
              session and specifies options for it.

       All keyword names can be abbreviated to a minimum of 4 characters.


       This section, named  options,  specifies  general  options  to  use  by
       vtund(8).  Possible keywords are:

       type stand|inetd
              server  type.  vtund(8)  can operate in standalone mode (stand),
              that is the default, or be invoked from inetd(8).

       port portnumber
              server port number to listen on  or  connect  to.   By  default,
              vtund(8) uses port 5000.

       timeout seconds
              General timeout.

       persist yes|keep|no
              persist  mode.   If yes, the client will try to reconnect to the
              server after connection termination.  If keep, the  client  will
              not   remove   and   re-add  the  tunXX  or  tapXX  device  when
              reconnecting.  If no, the  client  will  exit  (default).   This
              option is ignored by the server.

       syslog number|name
              syslog  facility  specification,  either  numeric  or name (from
              syslog (3)).

       ppp path
              path to pppd(8) program.  Can be used in session sections.

       ifconfig path
              path to ifconfig(8) program.  Can be used in session sections.

       route path
              path to route(8) program.  Can be used in session sections.

       ip path
              path to iproute(8) program.  Can be used in session sections.

       firewall path
              program for the firewall setup.

       All the ppp, ifconfig, route and  firewall  parameters  can  specify  a
       filename  for  corresponding  program  or equivalent (or shell script).
       This  parameters  are  used  in  session  sections  to  setup   network


       Session  options  can  be  specified  inside  session section or inside
       default section.  Default parameters apply to any session  section  but
       can be overwritten there.  Parameters are:

       password secret
              password  for authentication.  This should be the same in client
              and server.

       type type
              type of tunnel.  Possible tunnel types are:

              tun    IP tunnel (no PPP, Ether etc headers)

              ether  Ethernet tunnel

              tty    serial tunnel (PPP, SLIP etc)

              pipe   pipe tunnel

              Default tunnel type is tty.  This option is ignored by client.

       device dev
              network device to use.  You can choose tapXX for ether tunnel or
              tunXX  for  tun  tunnel.  By default vtund(8) will automatically
              select available device.

       proto tcp|udp
              protocol to use.  By default, vtund(8) will  use  TCP  protocol.
              UDP  is recommended for ether and tun tunnels only.  This option
              is ignored by the client.

       timeout secounds
              Connect timeout.

       compress method[:level]
              specifies  compression  method  to  use.   Compression   methods

              no     no compression

              yes    default compression method

              zlib   ZLIB compression

              lzo    LZO compression (if compiled in)

              You  can also specify level of compression using one digit (1 is
              best speed, 9 is best compression ratio).  This  option  ignored
              by the client.

       encrypt yes|no
              enable  or  disable  encryption.   This  option  ignored  by the

       keepalive yes|no
              enable or disable connection keep-alive.  This option is ignored
              by the client.

       stat yes|no
              enable  or  disable  statistics.   If  enabled vtund(8) will log
              statistic counters to /var/log/vtund/session_X every 5  minutes.

       speed kbps
              specifies  speed  of  the  connection in kilobits/second.  Valid
              values for kbps are  8,16,32,64,128,256,etc.   0  (the  default)
              means  maximum  possible speed without shaping.  You can specify
              speed in form in:out, where in is speed to client,  out  -  from
              the  client.  Single number means the same speed for in and out.
              This option ignored by the client.

       srcaddr list
              local (source) address. Used to  force  vtund  to  bind  to  the
              specific address and port.  Format:
                srcaddr {
                 option value;
                 option value;

              srcaddr options:

              iface if_name
                     use interface address if_name as the source address.

              addr addr
                     source address.  Can be either IP address or host name.

              port portnumber
                     source port.

       multi value
              control  multiple  connections.   value  can  be yes or allow to
              allow multiple connections, no or deny to deny them  or  killold
              to  allow  new  connection  and  kill  old  one.  Ignored by the

       up list
              list of programs to run after connection has  been  established.
              Used  to  initialize  protocols,  devices, routing and firewall.
              This option looks like whole section inside of session  section.
               up {
                 option value;
                 option value;

              Options inside up (and down) blocks:

              program path arguments [wait]
                     run  specified  program.   path  is  the full path to the
                     program,  arguments  is  all  arguments  to  pass  to  it
                     (enclosed  in  double  quotes).  If wait specified, vtund
                     will wait program termination.  Special  characters  that
                     can be used inside arguments parameter:

                     %a - Remote IP address
                     %p - Remote TCP or UDP port

              ppp arguments
                     run   program  specified  by  ppp  statement  in  options
