You are welcome. A number of random points: * My code sends the DDCMP frames out as UDP datagrams, and receives frames the same way. You simply specify src/dst ports, and possibly an address (defaulting to 127.0.0.1). This means that there is no need to do elaborate (blocking) setups of TCP connections etc. from inside the simulator. This also makes it trivial to connect two simulators running on the same machine, or on the same (trusted) LAN. * A side effect of this is that you can have a helper process on your machine that does the TCP magic and also encrypts the traffic out on the evil internet. My normal (at the moment defunct) setup is done that way. One such program is on the site, named "stuk2.c" (don't ask...) * You can in theory write a helper process to talk to some real piece of hardware. I have not tested, but it should work to send the frames to a serial port and connect it to a real machine running async DECnet on a terminal line... * The current crypto in stuk2 is weak. Not the algorithm itself, RC4 (tm) is used, but some random padding etc. should be applied on the data stream, since it normally consists of 6-byte idle frames, with mostly known bits... * The actual KS10 supports one KDP with 2 DUPs. There are several reasons for this, like unibus load, unibus space and speed. This places some limits in case one wants to build a network of emulators and want to run both ANF and DECnet. The KMC itself supports 16 if I remember correctly. We should have at least 6-8, and allow for a fairly simple mod to Tops10 to handle them. * I am willing to help out, but I have very limited time until after the CuG conference, mid May. > Regards > > Rob --Johnny _______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
