multinet - Connect to a Multinet* DECnet over IP server
Contents
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.

The protocol used here was reverse engineered by Mark Berryman and Christine Caulfield.

Name
multinet - Connect to a Multinet* DECnet over IP server
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. IMPORTANT: Due to a kernel bug you should not use this option
unless you are using a Linux kernel version 2.6.17 or later.
-ppriority
Router priority. Default is 64
-Pport
Port to talk to Multinet on (default is 700). Ony change this if you know the Multinet server is
listening on a different port
-mMTU Maximum size of packets. (default 576)
-tsecs
Timeout for IP connections. If no traffic is seen on the IP connection after this time then the
daemon will attempt to restart it.
-Hhellotimer
How often HELLO messages are sent (default 60) in seconds.
