Re: [Simh] Ethernet Windows binaries for 3.9?

[Mark Pizzolato - Info Comm]

Hi Paul,

Simh V3.9-0 windows binaries which will work with or without network support 
(depending on whether WinPcap is installed) can be downloaded from:

https://github.com/downloads/simh/simh/simhv39-0-Win32Binaries.zip

Subject: [Simh] Ethernet Windows binaries for 3.9?

I've been using 3.7.x for a while, and thought I should upgrade to 3.9, 
particularly in order to get network loopback from SIMH client (VAX) to host 
(Windows XP). I'm confused as to whether I can use the windows binaries on 
trailing-edge.com - in the past I think I had to explicitly acquire binaries 
with Ethernet support (I have WinPCap).

It says:
>> Download a zip file containing Windows executables for all the SIMH 
>> simulators.  The VAX and PDP-11 are compiled without Ethernet support.

So, where do I find binaries with Ethernet support for 3.9?

Regards,

Re: [Simh] Connecting to Ethernet

[Sergey Oboguev]

Did you remember to configure the interface in TCP/IP services for OpenVMS?

Assuming for the sake of example that your host uses IP address 192.168.21.3 
for 

(initially) eth0 and (subsequently after bridging) br0, and assuming you want 
to 
assign 

IP address 192.168.21.200 to VAX instance, you need to configure QE0 inside VMS 
as follows:

$ TCPIP SET INTERFACE QE0 /HOST=192.168.21.200 
$ TCPIP SET CONFIGURATION INTERFACE QE0 /HOST=192.168.21.200

Depending on exact value of network addresses being used and network topology 
it 

may be necessary to additionally specify options /NETWORK_MASK=n.n.n.n and 
/BROADCAST_MASK=m.m.m.m, although usually VMS TCP/IP picks correct defaults for 
the masks.

If it still does not work, please post the output of

$ TCPIP SHOW INTERFACE /FULL
$ TCPIP SHOW ROUTE /FULL

and (in Linux)

ifconfig br0
ifcongig eth0
ifconfig tap0
brctl show
brctl show br0
brctl showmacs br0
route -n

and (at SIMH command console prompt)

show xq

Thanks,
Sergey

That was a big help, but I'm not there yet.  I did the following

$ sudo ./ linux-tap.sh create br0 eth0 tap0 david
$ sudo vax; to start SIMH
simh>   ; the usual stuff
simh> set xq mac=bla bla
simh> att tap0  ;  hooray, this is the first time this succeeded.
simh> boot cpu

When logged into VMS, I could PING and TELNET to LOCALHOST (and 127.0.0.1).   
But alas, not to my physical host.  And my physical host can't see the VAX 
either.

But I did so many things to get to this point that something else might be 
screwed up, so I need to reboot linux and start this drill again.

Thanks for a great start!

Any other suggestions?

Perhaps because 

    /usr/sbin/tunctl -t $TAPDEV -u $USERID

is missing.

You may find the following script helpful:  
http://oboguev.net/misc/linux-tap.sh.txt

Usage is at the bottom or invokable as

    ./linux-tap.sh help

I agree that (see below) is a good, detailed reference.  I found this one to 
good too, but Lennert is creating a Cluster and installing DECNet, both 
non-novice operations.  So the reader has to kind of edit the procedure:

https://vanalboom.org/node/18

A few comments are in order:

1. HP's license package includes a UCX, not TCP license.  I doubt a novice 
would recognize that the UCX license works fine for TCP.

2. Interfacing to Ethernet is a bag of worms.  Lennert's discussion is dated 
because Jordi points out that SIMH 3.9 has added functionality.  See 

http://ancientbits.blogspot.com.es/2012/06/simh-39-using-vde-for-fun-and.html

But his example doesn't work either.  In particular I get the following error:

david@Thinkpad:~$ sudo brctl addbr br0
david@Thinkpad:~$ sudo ifconfig tap0 up
tap0: ERROR while getting interface flags: No such device
david@Thinkpad:~$ 

3. VMS has several editors available.  If the user isn't careful, editing files 
could be very frustrating.  The following works:

$ SET TERMINAL /DEVICE=VT100
$ EDIT MODPARAMS.DAT

The following doesn't

$ SET TERMINAL /DEVICE=VT200
$ EDIT MODPARAMS.DAT

To see which terminal-type SIMH defined, use the command:

$ SHOW TERMINAL

To add to the confusion, the following works in either case (because it's a 
different editor)

$ EDIT/EDT MODPARAMS.DAT

Well, I'm belaboring the point.  There are several books available that 
describe basic VMS commands, keyboarding, functionality etc.:

Duffy, Getting Started with OpenVMS
Holmay, The OpenVMS User's Guide
Rice et al, Introduction to OpenVMS

So, I have SIMH/VAX running and I'm pleased with all of your fine comments, 
suggestions and assistance.   Thank you very much!

David.

I know very little about VMS, but I found this to be a great guide:
