NAME
       vtund - VTun(Virtual Tunnel) daemon.

SYNOPSIS
       vtund < -s > [ -i ] [ -n ] [ -f file ] [ -P port ]

       vtund [ -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
       -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.
