NAME

       vtund - VTun(Virtual Tunnel) daemon.

SYNOPSIS

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

       vtund  [  -f  file  ] [ -P port ] [ -p ] [ -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.

       -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.
