NAME

       vtund - VTun(Virtual Tunnel) daemon.

SYNOPSIS

       vtund < -s > { -4|-6 } [ -i ] [ -n ] [ -f file ] [ -P port ]

       vtund  {  -4|-6 } [ -f file ] [ -P port ] [ -p ] [ -q ] [ -m ] [ -t timeout ] [ -n ] < session > < server
       address >

DESCRIPTION

       VTun provides the method for creating Virtual Tunnels over TCP/IP networks and allows to shape, compress,
       encrypt traffic in that tunnels.

       Supported type of tunnels are: PPP, IP, Ethernet and most of other serial protocols and programs.

       VTun  is  easily  and  highly  configurable, it can be used for various network task like VPN, Mobile IP,
       Shaped Internet access, IP address saving, etc.

       It is completely user space implementation and does not require modification to any kernel parts.

OPTIONS

       -4     Use IPv4 for transport, and for listening  socket.  This  is  the  default  choice.   Any  of  the
              addressing modes IPv4 or IPv6 can passed inside the tunnel.  The decision to use either is made by
              the ifconfig and ip commands.

       -6     Choose IPv6 as transport layer, and server listening socket.

       -f file
              Read config information from the file (full path required). By default vtund uses /etc/vtund.conf

       -n     Do not become daemon.

   Server mode:
       -s     Run as the server.

       -i     Run as the inetd server.

       -P port
              Listen for connection on the specified port By default  vtund  listens  on  TCP  port  5000.  This
              options is equivalent to the 'port' option of config file.

   Client mode:
       -P port
              Connect  to  the  server  on  the  specified port By default vtund connects to TCP port 5000. This
              options is equivalent to the 'port' option of config file.

       -p     Reconnect to the server after connection termination. By default vtund will exit if connection has
              been terminated. This options is equivalent to the 'persist' option of config file.

       -q     Inhibit the printing of connection messages.

       -m     Force memory pages to be locked memory-resident to prevent potential VM deadlock.  Useful with NFS
              traffic.  This option has no config file equivalent.

       -t timeout
              Connect timeout Default is 30 seconds. This options is  equivalent  to  the  'timeout'  option  of
              config file.

       session
              Session name from the config file.

       server Address of the server to connect to. Either IP address or domain name can be specified.

FILES

       /etc/vtund.conf
              Main configuration file with sessions and other information.  See vtund.conf example provided with
              distribution and vtund.conf(5) for more information.

       /var/lock/vtund/
              Session lock files.

       /var/log/vtund/
              Connection statistic log files.
              Format:
                 Date Uncomp_In Uncomp_Out Comp_In Comp_Out

SIGNALS

       SIGHUP Server mode: Causes vtund to reread the config file.
              Client mode: Causes vtund to reestablish the connection.

       SIGUSR1
              This signal causes vtund to reset statistic counters.
