Hmm. BEA is 1.19, not 1.20.
1.20 is KNASE. Another PDP-11/70 running RSX.
You can put me as responsible for both of them for now. It might be some other person for KNASE eventually, but at the moment we have some hardware problems with that machine.

So, obviously my iptables ain't blocking DECnet,
so it's a mystery why I can only see:
pc:/etc# cat /proc/net/decnet_neigh
Addr Flags State Use Blksize Dev
1.500 --- 40 01 0001498 eth0
1.10 --- 40 01 0016434 lo

Yeah, I can see how one would think that... however,
I just figured out that I have to learn iptables now...
I'm running fail2ban, and that setup IPtables as:
pc:/# iptables --list
Chain INPUT (policy ACCEPT)
target prot opt source destination
fail2ban-ssh tcp -- anywhere anywhere multiport dports ssh,sftp
Chain FORWARD (policy ACCEPT)
target prot opt source destination
Chain OUTPUT (policy ACCEPT)
target prot opt source destination
Chain fail2ban-ssh (1 references)
target prot opt source destination
RETURN 0 -- anywhere anywhere
so now I have to figure out how to punch holes in the firewall
for UDP/4711 to let DECnet traffic through, and I'm a newbie
to iptables... so am reading documents, so that I don't break
what fail2ban is already doing here.

Depending on your distribution you should be able to do a
yum install libpcap-devel
or
apt-get install libpcap-dev
or something similar
Actually on my old debian system it's called libpcap0.8-dev

I've created a simple DCL script that will allow me to maintain a simple
list of the Multinet tunnels and a DNS name. The script will do an NSLOOKUP
on the name to figure out the corresponding IP and then re-configure the
Multinet connections accordingly. Like the bridge program, this isn't
automatic and you'll have to send me an email when your IP changes to remind
me to re-run this script. And since changing the destination IP requires
turning the circuit off and then restarting it, any existing connections on
that circuit (including any that are routed thru you) will be broken. Given
the fairly low level of usage on HECnet, that doesn't seem like a big
problem.
If you already have a Multinet connection to LEGATO with a static IP, then
you can just ignore this message. Nothing will change for you.
Fred - it's time for you to go sign up for that Multinet Hobbyist license

Maybe I should point out that for the bridge program, all you need to do is send it a HUP signal, and it will redo the name lookups. However, there is always a possibility that the old resolving information is still cached somewhere, so that you won't the to the new address right away anyhow. How long the delay depends on how the name server and domains are set up.
But if someone have a dynamic IP, but it changes fairly seldom, it usually works acceptable anyway, so having a dynamic IP address isn't neccesarily the end of it all.

Looks like that will be my project for this weekend. Good excuse to get my DECServer 90M hooked up to the console port, too. I'll get the license process underway tonight so I'm ready ...
Will send another message to the list once I'm up and running with Multinet. As far as the e-mail with new IP address goes, I could whack together a batch job on OpenVMS or cron job on one of the Linux boxen that will keep an eye on things and check every so often, and e-mail the address you specify Bob when the address changes.

It's hobbyist licence.

When you register, it checks your VMS licence checksum, but I don't know
what it does with it.

Zarqon is back up at the moment (it's nice and cold here ... in

Sorry, but no.
While I do name lookups, I'm not doing it for every packet that goes out, or comes in. It's done at startup, and when the config file is re-read. So if someones address change, the bridge program will "stop working".

Would someone know of a dynamic-address friendly method? I have DSL here, and switching to cable isn't an option as they block ports and are generally nasty around here. Static DSL is a last resort option as I'd rather not double my DSL bill if I don't have to.
I do not want anyone to have to "babysit" my connection to the network - if there's any babysitting to be done, I'll do it - or write some DCL to automate it, or what-have-you.
Do I have any options?
