11/44 vs. 11/84, was Re: [HECnet] NT 4 on AlphaServer es40

On 02/13/2013 12:53 PM, Johnny Billquist wrote: I can believe that the 11/84 made the 11/44 obsolete, however. They fulfill the same niche, with the 11/84 being faster, smaller and probably cheaper. How is the 11/84 smaller? It was available in two chassis: one that's takes up about two feet of rack space, and one standard 6U box. The 11/44 is a 6U box as well. Were there other packagings of these machines of which I'm unaware? -Dave -- Dave McGuire, AK4HZ New Kensington, PA

The AUI port already defines you at 10 Mb/s. You need a different ethernet controller, as the speed is decided by the controller and not the PHY. On the Alpha it does, but I have never tried the VAX, I would think it should, it does in the Stromasys and Simh emulators, but I'm guessing. That is because Alphas actually might have a 100 Mbit/s ethernet controller. No VAX that I know of do. An emulated machine is a totally different topic. There you are still emulating a 10 Mb/s interface, even though it might map towards a 100 Mb/s physical backend. There are faster network interfaces for VAXen, just not Ethernet.

DECnet-Plus and Phase IV Issues

On 13 Feb 2013, at 16:22, Kari Uusim ki <uusimaki at exdecfinland.org> wrote: DECnet-plus (or as called in Tru64unix ; DECnet-OSI) includes everything needed to communicate with DECnet Phase IV nodes. It is only a matter of configuration. You can use the DECnet-plus for OpenVMS documentation, because NCL vocabulary is exactly the same on both platforms. On Tru64unix the other DECnet related commands differ from OpenVMS; like SET HOST -> dlogin DIR -> dls etc The DECnet-plus documentation resides at: http://h71000.www7.hp.com/doc/decnetplus.html Are you trying to configure your Tru64unix system to communicate with HECNET Phase IV nodes? If so, why don't you just use the provided configuration tool? That's a lot easier than trying to accomplish the configuration manually. Yes. And I would use the tool...except it segfaults when I run it. On 13.2.2013 22:26, b4 at gewt.net wrote: Can you point me to documentation that mentions how to integrate it with Phase IV?

You should first shut the DECnet-plus (DECnet-OSI) down to remove all the entities before you can try to create and enable them again. There should be template scripts on the system which you can edit to make them suit your configuration. It would help a lot to read the DECnet-plus manuals to get a clear picture of how it works and how to manage it.

I should point out that you *can* put that information into NCP on RSX, it's just that you don't *need* to. And VMS is just being plain silly to scan through the nodename database in the case where the MOP request have an explicit file name in the request. The NCP database is then only potentially used for one thing - if you want to not serve the MOP request. I have not checked RSX here, but I wonder if it only do the scan in the case no filename is provided, or if it always do the scan anyway also on RSX. Either way, RSX responds before VMS even to seem to start thinking about it.

But even so, it is surprising that even a fairly modern VAX can't keep up with a PDP-11 here. Funny thing: a real VAX (VS 4000/60) can't keep up with an EMULATED PDP-11 running in a Raspberry Pi ;) I had to disable service in the emulated PDPs or else they tried to serve the OS to my 4000/90 ;) Really? Are you sure that does not have more to do with the fact that the VAX only has a 10M NIC where as the Raspberry Pi has a 10/100 NIC. I have not clocked the virtual 11/83 on my RPI but the virtual VAX runs at about 1.6 VUPs.
