vtdaemon

vtdaemon(1M)															      vtdaemon(1M)

NAME

       vtdaemon - respond to vt requests

SYNOPSIS

       lan_device lan_device ...

DESCRIPTION

       responds  to  requests from other systems (via local area network) made by (see vt(1)).	spawns a server to respond to each request that it
       receives.

   Options
       recognizes the following command-line options and arguments:

	      Causes	to rebroadcast all requests received on one lan device to all other lan  devices  specified  on  the  command  line.   The
			optional  parameter  ngateway specifies the maximum number of vtgateway servers that can be in operation concurrently.	If
			ngateway is not specified, there is no limit on the number of vtgateway servers that can be in operation concurrently.

	      Causes	vtdaemon to ignore all requests that have come through a gateway.

       The remaining arguments are the full path names of lan devices that vtdaemon looks for requests on.  If no lan devices are  specified,  the
       default lan device is used.

       The major number for this device must correspond to a IEEE 802.3 local area network device.

       Another	function  of is to create portals and service portal requests.	A portal is a callout device that can be used by to communicate to
       another machine via local area network (see uucico(1M)).  Portals are created by according to the configuration information  found  in  the
       file Each line in has the format:

	      <calldev>[,<lan device>] <nodename>

       For  each  line,  creates a portal named calldev in Whenever this device is opened, spawns a server that creates a connection to the system
       specified by nodename via the lan device specified.  If no lan device is specified, the first one specified on the command  line  when  was
       started is used (or the default lan device is used if no lan devices were specified on the command line).

       should be terminated by sending signal to it.  When receives this signal it removes all of the portals it created in before exiting.

       for these changes to take effect, or you can manually start both daemons by typing :
