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 con-
	      fig 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.
