how can I check in TOPS-20 to see if the device is visible and then install DECnet?
You need to install DECnet first. It's pretty easy.See http://ia801607.us.archive.org/21/items/bitsavers_decpdp10TOTMTOPS20DECnet20ProgrammersGuideJan80_10120529/AA-5091B-TM_TOPS-20_DECnet-20_Programmers_Guide_Jan80.pdf
ps:<system>4-1-config.cmd add 1 line: NODE name number (e.g. NODE HAPPY 7.3) ps:<system>sysjob.runLook for last job. If FAL or NETCON is missing, add as follows at end of file:
JOB <n+1> \LOG OPERATOR XX OPERATOR ENA RUN SYS:FAL \ JOB <n+2> \LOG OPERATOR XX OPERATOR ENA RUN SYS:NETCON \ (n.b. XX is literal - NOT the operator password.) Reboot $opr opr> enter ncp ncp> show known lines ncp> show known circuits ncp> exit opr> exit(Add char, stat, or count to the show commands as desired. ? will give in-line help.)
inf decnet for quick node status. For TOPS-10:MONGEN will prompt for the DECnet node name/number, etc. Build & boot the monitor.
.resources should (I think) show KDP, and you should see KDPLDR run at startup
.r opr (same) or .network /anf .network /decnet .node <name> for reachability of a node Enjoy. This communication may not represent my employer's views, if any, on the matters discussed. On 18-Apr-13 14:58, Rob Jarratt wrote:

Does that mean we can get DECnet running on TOPS-10 on SIMH? I would love to know how you actually install and set it up on TOPS-10. I will try to find some time to get the KMC/DUP into the latest SIMH.You are welcome. A number of random points:I have compiled something very basic into PDP10, the network code is actually stubbed out at the moment as I have to replace it with current SIMH code (going to look at TMXR). In the meantime, how can I check in TOPS-20 to see if the device is visible and then install DECnet? I remember finding some docs but I can't find them again now.* 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...Not sure what you are referring to here. Thanks Rob* 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_______________________________________________ Simh mailing list [email protected] http://mailman.trailing-edge.com/mailman/listinfo/simh
