VTUND(8) NAME vtund - VTun(Virtual Tunnnel) daemon. SYNOPSIS vtund < -s > [ -f file ] [ -P port ] vtund [ -f file ] [ -P port ] [ -L address ] [ -p ] [ -t timeout ] DESCRIPTION VTun provides the method for creating Virtual Tunnels overTCP/IP networks and allows to shape, compress, encrypt traffic in that tunnels. Supported type of tunnels are: PPP, SLIP and most of other serial protocols and programs Ethernet via Linux's EtherTap device. VTun is easily and highly configurable, it can be used for various network task like VPN, Mobil 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 By default vtund uses /etc/vtund.conf Server mode: -s Run as the 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. -L address Use specified local address to connect to the server. Useful for the hosts with several interfaces and addresses. -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. -t timeout Connect timeout Default is 30 sec. This options is equvalent to the 'timeout' option of config file. host Host to authentificate with the server. Password and other information of this host will be taken 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 hosts and other infor mation. It specifies authentification keys, speed of connections, options to pass to the programms, etc. Format of the file completely described in example provided with distribution. SIGNALS SIGHUP This signal causes vtund(server mode) to reread config file. NOTES Currently VTun works under the Linux(x86, Alpha) but can be easily ported to other Unices. Comments, ideas and if possible patches are always welcome. AUTHORS VTun has been derived from VPPP package by Maxim Krasnyansky. Maxim Krasnyansky max_mk@yahoo.com
