@@ -8,7 +8,7 @@ DELQA (M7516) and DEQNA (M7504) Q-bus ethernet cards for the SIMH emulator.
The XQ emulator uses the Sim_Ether module to execute host-specific ethernet
packet reads and writes, since all operating systems talk to real ethernet
cards/controllers differently. The host-dependant Sim_Ether module currently
supports Windows, Linux, NetBSD, and OpenBSD.

Currently, the Sim_Ether module sets the selected ethernet card into
promiscuous mode to gather all packets, then filters out the packets that it
@@ -20,53 +20,138 @@ should not cause much of a problem, since the switch will still filter out
most of the undesirable traffic. You will only see "excessive" traffic if you
are on a direct or hub(repeater) segment.
Using the libpcap/WinPcap interface, the simulated computer cannot "talk" to
the host computer via the selected interface, since the packets are not
reflected back to the host. The workaround for this is to use a second NIC in
the host and connect them both into the same network; then the host and the
simulator can communicate over the physical LAN.
Universal TUN/TAP support provides another solution for the above dual-NIC
problem for systems that support Universal TUN/TAP. Since the TUN/TAP interface
is at a different network level, the host can create a TAP device for the
simulator and then bridge or route packets between the TAP device and the real
network interface. Note that the TAP device and any bridging or routing must be
established before running the simulator; SIMH does not create, bridge, or
route TAP devices for you.
-------------------------------------------------------------------------------
Windows notes:
1. The Windows-specific code uses the WinPCAP 3.0 package from
http://winpcap.polito.it. This package for windows simulates the libpcap
package that is freely available for unix systems.
package that is freely available for un*x systems.
2. You must *install* the WinPCAP runtime package.
3. The first time the WinPCAP driver is used, it will be dynamically loaded,
and the user must be an Administrator on the machine to do so. If you need
to run as an unprivileged user, you must set the service to autostart. See
the WinPCAP documentation for details on the static load workaround.
4. WinPCAP loops packet writes back into the read queue. This causes problems
since the XQ controller is not expecting to read it's own packet. A fix
to the packet read filter was added to reject packets from the current MAC,
but this defeats DECNET's duplicate node number detection scheme. A more
correct fix for WinPCAP will be explored as time allows.
the WinPCAP documentation for details on the static loading workaround.
4. If you want to use TAP devices, they must be created before running SIMH.
(TAP component from the OpenVPN project; http://openvpn.sourceforge.net)
5. Compaq PATHWORKS 32 v7.2 also enabled bridging for the ethernet adapters
when the DECNET and LAT drivers were installed; TAP was not needed.
Building on Windows:
1. Install WinPCAP 3.0.
1. Install WinPCAP 3.0 runtime and the WinPCAP Developer's kit.
2. Put the required .h files (bittypes,devioctl,ip6_misc,packet32,pcap,
pcap-stdinc).h from the WinPCAP 3.0 developer's kit in the compiler's path
3. Put the required .lib files (packet,wpcap).lib from the WinPCAP 3.0
developer's kit in the linker's path
4. If you're using Borland C++, use COFF2OMF to convert the .lib files into
a format that can be used by the compiler.
5. Define USE_NETWORK if you want the network functionality.
6. Build it!
-------------------------------------------------------------------------------
Linux, NetBSD, and OpenBSD notes:
Linux, {Free|Net|Open}BSD, OS/X, and Un*x notes:
1. You must run SIMH(scp) as root so that the ethernet card can be set into
promiscuous mode by the driver. Alternative methods for avoiding the
'run as root' requirement will be welcomed.
Building on Linux, NetBSD, and OpenBSD:
1. Get/install the libpcap package for your unix version. http://rpmfind.net
might be a useful site for finding the linux variants.
2. Use Make USE_NETWORK=1 if you want the network functionality.
2. If you want to use TAP devices, they must be created before running SIMH.
Linux, {Free|Net|Open}BSD, OS/X, Un*x notes:
1. Get/make/install the libpcap package for your operating system. Sources:
Linux : search for your variant on http://rpmfind.net
OS/X : Apple Developer's site?
Others : http://sourceforge.net/projects/libpcap/
2. Use 'make USE_NETWORK=1' if you want the network functionality.
3. Build it!
-------------------------------------------------------------------------------
OpenVMS Alpha notes:
1. Ethernet support will only work on Alpha VMS 7.3-1 or later, which is
when required VCI promiscuous mode support was added. Hobbyists can
get the required version of VMS from the OpenVMS Alpha Hobbyist Kit 3.0.
Running a simulator built with ethernet support on a version of VMS prior
to 7.3-1 will behave as if there is no ethernet support built in due to
the inability of the software to set the PCAPVCM into promiscuous mode.
An example display of fully functional ethernet support:
sim> SHOW XQ ETH
ETH devices:
0 we0 (VMS Device: _EWA0:)
1 we1 (VMS Device: _EWB0:)
An example display when the simulator was built without ethernet support
or is not running the required version of VMS:
sim> SHOW XQ ETH
ETH devices:
no network devices are available
2. You must place the PCAPVCM.EXE execlet in SYS$LOADABLE_IMAGES before
running a simulator with ethernet support.
3. You must have CMKRNL privilege to SHOW or ATTACH an ethernet device;
alternatively, you can INSTALL the simulator with CMKRNL privilege.
4. If you use a second adapter to communicate to the host, SOME protocol
that creates an I/O structure (SCS, DECNET, TCP) must be running on the
adapter prior trying to connect with SIMH, or the host may crash.
The execlet is not written to create an I/O structure for the device.
Building on OpenVMS Alpha:
1. Build the PCAP library and execlet. They are in the [.PCAP-VMS]
directory in the simh source distribution. The following builds
both the pcap library and the pcap execlet:
$ set def [.pcap-vms]
$ @build_all
Building VCI version of pcap...
Building the PCAP VCM execlet...
In order to use it, place PCAPVCM.EXE in the
SYS$LOADABLE_IMAGES directory.
%DCL-I-SUPERSEDE, previous value of PCAPVCM$OBJ has been superseded
To use the PCAPVCM.EXE execlet you must copy it to
the SYS$LOADABLE_IMAGES directory.
Build done...
2. To build the simulators with ethernet support, you
need to build them with MMS or MMK as follows:
$ MMx/MACRO=("__ALPHA__=1", "__PCAP__=1")
