 NAME    [Toc]    [Back]
      recserv - HP SharedX Receiver Service

 SYNOPSIS    [Toc]    [Back]
      /usr/lbin/recserv

 DESCRIPTION    [Toc]    [Back]
      HP SharedX Receiver Service provides a method for a receiver to allow
      the sharing of windows without explicitly performing any xhost
      commands.  The Internet daemon (inetd(1M)) executes recserv when it
      receives a service request at the port listed in the services data
      base for recserv (see inetd(1m) and services(4)).

      When recserv is executed via inetd, a dialog box appears informing the
      receiver of the share request by the sender.  The receiver can allow
      or disallow the share request by selecting the YES or NO button.

      recserv allows sharing by xhosting the sender just long enough for it
      to make a connection to the receiver.  Once the connection is
      established recserv removes the sender from the access control list,
      unless the sender was entered in the list prior to the execution of
      recserv. Since no permanent change is made to the access control list,
      security is maintained at its highest level.

      To start recserv from the Internet daemon, the configuration file
      /etc/inetd.conf must include the single line entry,

      recserv  stream tcp nowait bin /usr/lbin/recserv  recserv -display :0

      If the sharing is going to be done between IPv6 machines, the protocol
      field of the above entry in /etc/inetd.conf file of the receiver
      machine should be changed to tcp6 as follows

      recserv  stream tcp6 nowait bin /usr/lbin/recserv  recserv -display :0

      and the services file /etc/services must include the line,

      recserv         7815/tcp             # SharedX Receiver Service


      Receiver Service options, set by selecting the Options button, dictate
      the behavior of recserv. The behavior can also be set by running
      recserv manually.  In either case, an X server resource is set
      dictating the behavior for subsequent invocations of recserv.

 OPTIONS    [Toc]    [Back]
      The following options allow different behavior according to user
      preferences.

           AlwaysAsk    [Toc]    [Back]
                The dialog will pop up each time sharing is requested,

 recserv(1M)                                                     recserv(1M)




                regardless of the security on your X server.

           AlwaysAllow    [Toc]    [Back]
                The dialog box never appears, but sharing will always be
                allowed.

           AskUnhosted    [Toc]    [Back]
                The dialog will pop up only if the sender's machine is not
                hosted on your machine.  If the sender's machine is already
                hosted, sharing will occur without a dialog appearing.

           NeverAsk    [Toc]    [Back]
                The dialog will never appear.  Windows are shared only if
                the sender's machine is already hosted by your server.
      To set resources (system behavior, label strings, etc) globally for a
      system, edit the file /usr/lib/X11/app-defaults/RecServ.
