multinet(8) Connect to a Multinet* DECnet over IP server


multinet [options] <local-decnet-addr> <remote-host>


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. and is available free for hobbyist use.
The protocol used here was reverse engineered by Mark Berryman and Christine Caulfield.


Be verbose and dump packet contents to stderr
Advertise as a level 1 router
Advertise as a level 2 router (default)
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.
-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.
