Hi,
I've just assembled my kit and I'm trying to use some concepts. But, when using RSX11 with TCP/IP I receive an error msg from DHCP client and can't use networking tools (as ftp or ping).
How do I configure my simh to use the network device? I changed the boot.ini to attach eth to wlan0 and it's ok. Do I need to do some extra setup or it's another setting?
best,
Augusto Baffa

well... same with 211bsd... I guess there is something wrong my simh setup.

Actually, maybe you should start by telling what your config of simh is,
and what system image you grabbed, and if it includes DECnet...
Someone should really write up some kind of a howto for this thing. It
can be confusing to people how things are related and required to be set
up. DECnet implies that you need to use specific MAC addresses for your
simh setup, which, depending on host system, is something you might need
to handle manually.
I first responses to Augusto just saying he needed to reconfigure TCP/IP
in case there is no DHCP server on his network. Which is also a
possibility here. But there could be various different things that are
the problem.
I should also mention that TCP/IP in RSX today does not support link
local addresses. I might do that one soon. I just haven't come around to
it, nor seen a big need. But if someone just plugs things in, and there
is no DHCP, then at the moment, you might not have things working.

I have a DHCP server in my network and I think it's not the problem.
I prepared my pi using the default rasbian and following the instructions at https://obsolescence.wixsite.com/obsolescence/pidp-11-building-instructions as follows:
----------------------
sudo mkdir /opt/pidp11
cd /opt/pidp11
sudo wget https://www3.ispnet.net/pidp11/pidp11.tar.gz
sudo tar -xvf pidp11.tar.gz
sudo /opt/pidp11/install/install.sh
cd /opt/pidp11
sudo wget https://www3.ispnet.net/pidp11/systems.tar.gz
sudo tar -xvf systems.tar.gz
----------------------
cd /opt/pidp11
sudo wget https://www3.ispnet.net/pidp11/pidp11.tar.gz
sudo tar -xvf pidp11.tar.gz
sudo /opt/pidp11/install/install.sh
cd /opt/pidp11
sudo wget https://www3.ispnet.net/pidp11/systems.tar.gz
sudo tar -xvf systems.tar.gz
----------------------
and installed the decnet - packages latd dnet-progs
also... I configured my boot.ini to attach wlan0 instead of eth0

Augusto,
It would be helpful to see the /opt/pidp11/rsx11mplus/boot.ini file you are using. As Johnny said
RSX11M networking needs a valid DECnet MAC address which is set there.
Also, you mentioned that you configured boot.ini to use wlan0 instead of eth0
That may have something to do with it. The version of simh that the PiDP11 typically uses
eth0 and some have experimented trying to get wlan0 to work but you would need to take a look at forum
discussions on that topic.
Good Luck,
Mark

One thing to be aware of is that wlan is *not* the same as ethernet.
Not sure that is your only problem, but running simh interfacing to a
wlan shared by the host is often not working well.
DECnet packages installed on the host system are not needed, and not
even relevant around this.
I suspect that the RSX image contains DECnet. Which is important,
because the MAC address you should use is based on what DECnet address
is configured for the RSX system.
One workaround for some of your problems is to use a feature of simh,
where it adds an internal nat.
You could do that like this:
attach xu nat:tcp=21:10.0.2.15:21,tcp=23:10.0.2.15:23
With that line, you also have access to telnet and ftp from the outside
by connecting to the host system. For the rest of it, connecting from
the RSX host out will always work fine, but outside connecting in will
obviously fail, unless you are on the host system itself.
The address 10.0.2.15 is the address the RSX host will get if using DHCP.
Note that I'm not sure if PiDP-11 have a new enough simh to have this
functionality in there.
However, if you use proper ethernet, then just attaching your PDP-11
ethernet to the actual ethernet should work just fine.
Other options include creating a bridge. See
https://github.com/simh/simh/blob/master/0readme_ethernet.txt for more
information.

Ok. That would be for a DECnet address of 30.30. Looks like Mark
Matlock's RSX image, I think.
I think your primary problem is just that wlan just do not work like you
wish it would.
