[Simh] MicroVax 3900 Networking on a Macbook Air

[Zachary Kline]

Hi All,

I was wondering if anybody could give me some tips on networking with my MacBook air. I used to run a virtual VMS system a few years back, but that was on Windows and/or Linux, with access to “real,” ethernet devices.
I’ve since switched to the wifi-only Macbook Air, and it isn’t cooperating very well. My copy of TCPIP services fails to get a DHCP lease.
I know that bridging with wifi adaptors is problematic, but I built with the OS X native LibPcap support, and I thought it might help.

Here is my simh version info

		FrontPanel API Version 1
	Host Platform:
		Compiler: GCC 4.2.1 Compatible Apple LLVM 7.0.0 (clang-700.0.72)
		Simulator Compiled: Sep 30 2015 at 21:53:11
		Memory Access: Little Endian
		Memory Pointer Size: 64 bits
		Large File (>2GB) support

		OS: Darwin Zacharys-MacBook-Air.local 15.0.0 Darwin Kernel Version 15.0.0: Tue Sep 22 20:33:10 PDT 2015; root:xnu-3247.10.11.1.1~1/RELEASE_X86_64 x86_64

Show xq eth:

ETH devices:
 eth0	en0                                  (No description available)
 eth1	awdl0                                (No description available)
 eth2	bridge0                              (No description available)
 eth3	en1                                  (No description available)
 eth4	udp:sourceport:remotehost:remoteport (Integrated UDP bridge support)

en0 is the wifi adaptor I’m interested in, and bridge0 is an OS X-provided THunderbolt Bridge, which doesn’t seem particularly useful for my purposes.

Any advice would be appreciated. :)
Thanks much,
Zack.
