Re: [Simh] Tun/Tap in Mint for RSX-11M Plus 4.6 running in SimH PDP11

For my recent VAX installation on windows I used NAT and initially tested using an ethernet connection. I cannot telnet in but most outbound connections work. At least eliminate one area of possible trouble by using a wired connection for initial testing. On Sun, Jun 23, 2019, 9:07 PM Will Senn

This question may best be asked elsewhere but I'm struggling to make it work with SimH, so here it is :) tldr; How can I get tun/tap working with Mint 19 and SimH RSX-11M Plus 4.6 so that I can access the internet from the instance and telnet to it from another machine on the network?

The system that I set up for myself and for my friend (who needs one more disk than I do) was cloned from a VMS Cluster that has been in continuous operation in its present form for about 20 years, so the issue is not with mounting disks too early in the startup sequence. Not that this helps much

I can't remember having any such issues, but then again I also can't remember if I ever tried it with VAX. With PDP-11 it works without any issues. This is, though, another slight silliness in simh. The limit to 4 disks per controller is very artificial. The UDA50, KDA50, and maybe some

A vax emulator I was configuring for a friend (MicroVAX 3900 simulator V4.0-0 Current git commit id: ab3e07a4) needs to mount more than four disks. The .INI file has set rqb enabled and an associated attach command. In my VMS startup disks are mounted very close to the beginning of the boot
