The simh host gets a separate address. A third system can connect to the host os and to the emulated system(s). Simultaneously even. What doesn't work (IIRC) is an IP connection between the emulated system and its host, never mind which system initiated the session. Whether it works on your particular flavor of linux: don't know. But if the host supports the pcap library then I think it will.

I'd Ideally like to be able to SSH both the VAX and the Linux sides of the box. -- Mark Benson http://markbenson.org/blog http://twitter.com/MDBenson Verzonden vanaf mijn draadloze BlackBerry -toestel
