Provided that /dev/tty00 exists, and the major device type is set to the
cdevsw index for the DZ in whatever Unix you are using, and the minor device
is set to the correct value to DZ #0, line #0.... :-)

Please save cbosgd for me.  It may be awhile before I get around to 
doing anything with it.

There was never a cbosgd!mah, but now I have a shot at it :)

Use the 4.3BSD branch. In these systems, I've set the serial ports
as insecure in /etc/ttys, so people can't login as root. Then, remove
all users from the password file (with vipw) except root and uucp. Or,
keep one non-root user for you to login as.

If you leave vax780 running in 'screen', you can still login as root there.

That's the plan. I now have lanl-a and unmvax up and talking to each
other. If anyone would like to set up a bi-directional connection with
lanl-a, contact me off-list and I'll put you in my firewall / add a
serial connection to you. I'll try to get C-News going soon too.

I would put some kind of firewall in front of it, If even to restrict source addressed to well known.  There is a LOT of people scanning the internet.  I also have a publicly available FTP server and I'll see it on lists of known boxes etc.

I'm using Taylor UUCP on a somewhat modern system (Ubuntu 12).

I managed persuade it to connect to seismo over TCP port 5000 and do a
handshake for protocol g.  A few packets were sent.

Now I'll see if I can inject email messages into this.  We're using the
exim MTA, and it's does exactly support uucp.

Yes, I'm trying to work on that. There is a way set some DZ lines
to listen on port Y and the others on port X.

sim> ATTACH DZ X,Line=3,Y,line=4,Z

But there isn't a way to bind to localhost AFAICT. So we should be able to
run uucico only on certain /dev/tty lines, but this still will require
you to iptables block the other port.

Unless someone has a way to bind simh DZ lines to localhost?

I'm trying to do an identical test before bring UUCP up. (but using
4._3_BSD).

I've now got it working and it made me think a little.

In order to do these "serial ports over TCP" things, we basically are
putting login prompts out to the Internet. Is it possible to restrict
things so the only user allowed on ttyN is 'uucp', or should I just
put in iptables rules to only allow traffic from my UUCP peers?

No luck with tip, and I don't see any net connections. My .ini file
contains this:

set dz lines=8
set dz 8b
attach dz line=0,Connect=simh.tuhs.org:5000
att dz -m 6666

and I can 'telnet simh.tuhs.org 5000' from the host.

OK, try this: Edit your /etc/remote file to say this for dialer:

dialer:dv=/dev/tty00:br#9600:

Now try:

# tip dialer

which should connect out over /dev/tty00 to seismo via the TCP connection.
Hit Return a few times to see if there is any response. On your host system,
do netstat -a | grep ESTAB and see if there is a TCP connection to
simh.tuhs.org:5000.

I also forgot. To be able to send e-mail, you need to add seismo to the
list of known remote sites in /usr/lib/sendmail.cf:

CWseismo

Neither have I! But yes, feel free. In yur SimH .ini file, put (or change)
this line to say:

attach dz line=0,Connect=simh.tuhs.org:5000

which will connect /dev/tty00 to simh.tuhs.org port 5000. Then
set up your L.sys file with a line that says:

seismo Any;9 DIR 9600 tty00 "" "" ogin:--ogin:--ogin: uucp ssword: uucp

so that the uucp site seismo can be contacted via /dev/tty00. Then you
can try doing:

# echo hello there | mail seismo\!root
  <wait a few seconds>
# /usr/lib/uucp/uucico -r1 -sseismo -x7

and you should see the debug information with parts of the uucp conversation.

I'd like to join this network, but I don't know how to configure a UUCP
site.  I'm using Taylor UUCP 1.07.  I can probably figure things out
eventually but if someone has any hints, that would be helpful.

I'm looking to use TCP and protocol T, but I don't know if that's
appropriate.

Even more progress. I wrote a script to generate the uucp systems,
and given it a rough test. It's now here:

https://github.com/DoctorWkt/4bsd-uucp

and ready for people to download and try things out. I'm happy for
people to make changes, by adding them in as contributors.

We should add a file with uucp names, owners and connection details.
I'll do that soon.

Have at it!
