Hi Gérard,
Everything Dave said is true, AND part of the issue may be a need to configure
some details about the new NIC you've just installed. Specifically, you say it
is a server NIC and may include specific awareness of (and need configuration
details for) VLANs. Configuring this is likely also necessary to get an IP
address
on the interface.
The NICs were ip-configured for the window host.
Once useful LAN packets can be transmitted and received
by the host OS, that interface can be used by simh via WinPcap Or Npcap.
So I can try Npcap? I'll do that.
Once you know the host can use the interface.
Aside from this, on Windows, there is absolutely no need for simh simulators
to have dedicated network interfaces. The host system's primary interface can
readily be used by simh to communicate both with other external systems AND
directly with the host system (via IP).
Yes but the windows host system has to be in a vlan, and the emulated
VAXen on another. And I cannot share between 2 VAXen the same NIC
because I use Decnet and Decnet pushes a Decnet specific Mac address on
the NIC.
You should start with this and only try
to use a separate NIC if you observe specific problems.
Good Luck,
- Mark

Due to subtle differences in Windows drivers, sometimes WinPcap can't see a
NIC unless it has an IP address assigned to it (or some other protocol - that

that the NIC should appear to be "active" to the host). Also, certain version of
WinPcap had issues adding NICs, and the solution was to remove WinPcap and
re-install it to allow the installation procedure to generate the correct
registry
entries for the new NIC during the installation. Note that depending upon the
Windows driver, sometimes the NIC had to be "active" before the WinPcap
installation procedure could see the NIC to generate the correct registry
entries.
WinPcap has very limited support for a long time, and suggests use of the
NPcap product in this post from the WinPcap home page
(https://www.winpcap.org/):
15 September 2018
WinPcap, though still available for download (v4.1.3), has not seen an upgrade
in many years and there are no road map/future plans to update the
technology. While community support may persist, technical oversight by
Riverbed staff, responses to questions posed by Riverbed resources, and bug
reporting are no longer available.
Gordon Lyon, Nmap project founder, has created Npcap, a packet capture
library for Windows, that includes WinPcap compatibility and may be a
suitable replacement for WinPcap and WinPcap Pro. Information can be found
at https://nmap.org/npcap/.

Subject: EXT :Re: [Simh] winpcap problem
Hello,
I used the recommended tool windump -D and it doesn't see the new NICs.
So it is a pure problem of compatibility between Winpcap and the new NICs.
Did anyone see a similar problem? Are there somewhere WinPcap gurus?

Hello,
I tried a reboot of the host. Same problem. Is it possible there are
NICs not compatible with WinPcap? or some bizarre configuration to do
on the NIC?

I have some trouble using winpcap (on windows) with simh.
I added a NIC (intel ethernet server adapter i350-t2), I can see it
on the windows configuration panel, but I don't see it using simh
"sho eth"
command, which uses winpcap (version 4.1.3). The other NICs are seen
by the same command.
Any help?
Winpcap has a problem with detecting newly installed network devices
that weren't present when the system was booted. Try rebooting the
system and see if you continue to see the same problem.
