MULTINET(8) System Manager's Manual MULTINET(8)NAME
multinet - Connect to a Multinet* DECnet over IP server
SYNOPSIS
multinet [options] <local-decnet-addr> <remote-host>
DESCRIPTION
This utility creates a tapX device and copies all the DECnet packets from that over IP to a remote Multinet* server. It provides a way to
connect a Linux box to a remote VMS machine over an IP-only network. Using Linux routing it should be possible to connect DECnet networks
over the internet using this technique.
local-decnet-addr DECnet node address of the tapX interface. This need not be the same as the address used on other interfaces but it might
be less confusing if it is.
remote-host IP address or host name of the remote Multinet server. If you send a HUP signal to the process it will lookup this name again,
so you don't need to restart the server if the remote node changes its IP address.
*Multinet is a product, and probably a trademark, of Process Software.
http://www.process.com and is available free for hobbyist use.
The protocol used here was reverse engineered by Mark Berryman and Christine Caulfield.
OPTIONS -v Be verbose and dump packet contents to stderr
-1 Advertise as a level 1 router
-2 Advertise as a level 2 router (default)
-D Make the tapX device into the default DECnet device. This will force all traffic to non-local nodes down the Multinet link. IMPOR-
TANT: Due to a kernel bug you should not use this option unless you are using a Linux kernel version 2.6.17 or later.
-p priority
Router priority. Default is 64
-P port
Port to talk to Multinet on (default is 700). Ony change this if you know the Multinet server is listening on a different port
-m MTU Maximum size of packets. (default 576)
-t secs
Timeout for IP connections. If no traffic is seen on the IP connection after this time then the daemon will attempt to restart it.
-H hello timer
How often HELLO messages are sent (default 60) in seconds.

XAddHost() XAddHost()
Name
XAddHost - add a host to the access control list.
Synopsis
XAddHost(display, host)
Display *display;
XHostAddress *host;
Arguments
display Specifies a connection to an X server; returned from XOpenDisplay().
host Specifies the network address of the host machine to be added.
Description
XAddHost() adds the specified host to the access control list for the server specified by display. The access control list is a primitive
security feature that allows access to the server only by other machines listed in a file on the machine running the server. On UNIX-based
systems, this file is called /etc/X?.hosts, where ? is the number of the server.
The application that calls XAddHost() and the server whose list is being updated must be running on the same host machine.
The address data must be a valid address for the type of network in which the server operates, as specified in the family member. Inter-
net, DECnet and ChaosNet networks are currently supported.
For TCP/IP, the address should be in network byte order. For the DECnet family, the server performs no automatic swapping on the address
bytes. A Phase IV address is two bytes long. The first byte contains the least significant eight bits of the node number. The second
byte contains the most significant two bits of the node number in the least significant two bits of the byte, and the area in the most sig-
nificant six bits of the byte.
For more information on access control, see Volume One, Chapter 15, Other Programming Techniques.
