recserv(1M)

NAME

recserv − HP SharedX Receiver Service

SYNOPSIS

/usr/lib/X11/SharedX/recserv

DESCRIPTION

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/lib/X11/SharedX/recserv recserv -display :0

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

recserv 7815/tcp # SharedX Reciever 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

The following options allow different behavior according to user preferences.

AlwaysAsk
The dialog will pop up each time sharing is requested, regardless of the security on your X server.

AlwaysAllow
The dialog box never appears, but sharing will always be allowed.

AskUnhosted
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
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.
