But are you trying to access this NAS from both home and while you're at the local coffee shop? So I have my home directory on my home server exported and mounted on a desktop, so when I login to either 'sail' or 'quad' I have the same files. So on sail (a Linux Mint Distro system) I just have: quad:/home /home nfs _netdev,auto,vers=3 0 0 in my /etc/fstab file. And of course I have an entry for quad in /etc/hosts as well, even though it's also in my local network DNS as well. Better safe than sorry. So anyway, the above mount tab entry mounts it on system bootup. John

Where do I put mount script?

by Kevin Stratton

I have a NAS that I am able to mount using NFS and I suspect that I can also mount as CIFS. I am currently using multicast DNS addresses in the addresses in my mount command and I do not want to use the numeric style IP addresses that seems to be required for /etc/fstab. Does anyone have suggestions where to place this mount command script? This command seems to needs root access, which may limit where the script with command will be placed.

Re: DECStation 3100 on a RPi2040...

by Jon "maddog" Hall

Kevin, I found two articles that gave more technical information on the exact problem. First of all is this issue of the chip that was used to supply "serial control" of various devices. Many people might not think about it, but the keyboard and mice are also "serial devices" and used up two ports of the four port DC7085 gate array: These systems have four asynchronous serial lines that are provided by a > DC7085 gate array. Of the four serial lines, only the third line has the > required modem control signals to support a modem. A 4-pin MMJ connector is > provided for the keyboard line, a 7-pin DIN connector for mouse line, and > two 6-pin MMJ connectors for printer and modem lines. > > Now we put in who articles about what lines and pins were actually implemented: http://www.vanade.com/~blc/DS3100/pinouts.html https://www.tuhs.org/Usenet/comp.unix.ultrix/1991-May/005327.html Now it appears as if the DS 3000 had two "serial ports", one designated for a modem and one designated for a printer. Reading them brings back more of the "issues". One issue is that many Unix systems were not used just as a desktop system, but as "servers" too. A prime example of this was that a VMS Workstation was only allowed a single user to be logged on at one time. A multi-user license was not allowed for VMS Workstations through a dictum put forward by VAX product management. This, of course, was not what Unix people (and particularly Sun customers) would do. They might have a single person using the keyboard, mouse and main screen, but have several others logged onto the system over TCP/IP. *You can now skip ahead to more about the issue of serial ports, but you will be missing an interesting part of DEC history:* For years DEC refused to sell a multi-user license to workstation users. We even had a separate product called Ultrix-32w which was both the Ultrix-32 software plus the graphical server and came with a two user license (so either uucp or the network administrator) could log in at the same time as the user at the main keyboard. However, no other general user could log in at the same time. So the base Ultrix-32w came with that two-user license, and there was no "upgrade". Eventually I found this "rule" so damaging to Digital's Unix business that I decided to fight it. This "rule" might have made sense in the original days of 1 million instructions/second CPUs and unaccelerated graphics, but made NO sense with the much faster and accelerated graphics. We were being whipped senseless by Sun's marketing team. So I traded this "rule" down, and finally found that it had been generated by Jesse Lipcon, at that time a VP of workstations. I called him up and explained the situation. "Oh, I NEVER meant that to apply to UNIX Workstations...only VMS Workstations" said Jesse. "The Unix market is much different." So I held a meeting the next week. I picked the largest meeting room, expecting there would be much argument. I made a huge presentation about the whole issue and how much business we were missing. I pointed out that it was really up to the customer how many people or processes would be on that system, and DEC should not be limiting it artificially. The day of the meeting, the room was packed. There were people standing in the hallways. I stood up at the front, made the presentation, and asked if anyone had objections. No one raised their hand. "Then why are you here?" I asked. "We just came to see the fireworks." was the answer. "Then Digital now sells multi-user workstations." I declared. Of course things were a little more complicated than that, since there were changes to documentation, licensing, and a whole project around adding another graphics tube, keyboard and mouse to the hardware (the "Multi-User Caylith" project), but we charged ahead with the multi-user system. *Back to the serial ports:* So the VMS viewpoint of workstations you *might* have a printer and a modem hooked to the workstation, but more likely these would be attached to a server someplace to be shared with other workstation users. From a Unix standpoint, your workstation might ALSO be a server, and might have a printer and modem OR TWO MODEMS attached to the workstation, On either serial port they worked fairly well at lower transfer speeds with handshaking, but with higher speeds the handshaking tended to break down, especially if you hooked a second modem up to the "printer port". Another issue was the lack of the "CD" line, that tells the system the modem has lost connection, and requires that the software on the system recognize this through a timeout. This violated the concept of "DECstandard 052", a standard that was developed for modems hooked up to DEC's systems. Before the adoption of "DECstandard 052" in order to hook a modem up to a computer and a country's telephone lines you had to test every modem with every piece of hardware and every operating system in every country. This was not only a very expensive process, but took a long time after operating system releases. By developing DECstandard 052 the company made this a lot easier. The hardware and operating system groups only had to certify against DECstandard 052, and customers could then connect up any "standard" modems and know that they had the modem control signals to reliably interact with the modems of the country. The DECstation 3100 did not meet DECstandard 052: DEC STD 052-0 Operational Requirements for Serial Terminals and Computer Interfaces Operating as DTEs Connected to EIA RS-232-C or CCITT V.28 Modems - Part: EL-00052-00 - 1981 We've run both UUCP and SLIP on 3100s here; the modem-control "problems" > really aren't that serious a problem unless you are a high-security sort of > place.

Unlikely? Yes. Impossible? No. Using the printer port for a modem made the issue even worse. After all, you did not expect the printer to talk back to you at high speed. So now you know the REST of the story. md On Sun, Jul 7, 2024 at 1:32 PM Kevin Stratton <kstratton(a)fastmail.us> wrote: > I found this information interesting. > > The statement > > "To save a couple of pennies per system the > > VAX hardware designers determined that having full hardware modem > > control (DECstandard 52) on the board was not needed, because "very > > few workstation users hook a modem up to their serial line". > > has two different meanings (to me) in the context of this discussion.

I found this information interesting. The statement "To save a couple of pennies per system the > VAX hardware designers determined that having full hardware modem > control (DECstandard 52) on the board was not needed, because "very > few workstation users hook a modem up to their serial line". has two different meanings (to me) in the context of this discussion. They are: 1) RI and DCD are not implemented in hardware (Ring indicator and data carrier detect) 2) A subset of RTS, CTS, DSR, DTR as well as RI and DCD are not implemented in hardware. Does anyone want to clarify this in greater detail? Just curious. On 7/6/2024 8:59 PM, Jon "maddog" Hall via WLUG wrote: > John: > > That's an interesting statement.

Re: DECStation 3100 on a RPi2040...

by Jon "maddog" Hall

John: That's an interesting statement. I would think it was the same case and port setup, but a different motherboard since you couldn't just slot a MIPS processor into a VAXstation processor. That is why I said "based". "Based" means that you did not have to requalify a lot of the parts, that you could use a lot of the same Bill of Materials....it does not mean you use exactly the same PCB. In the case of the VAXstation/DECstation 3100 that meant we used the same serial io chips and did not provide the hardware flow control. Yes! It's coming back to me, the 3100s were horrible for serial, > though I think they had fixed it for the 5000 series systems, since > the DECstation 5000 and the DECserver 5100 were identical, except the > DECStation had a graphics card and cost 10-20% _less_ than the > DECstation 5000. So we bought DECStations and used them as servers. The server groups were different engineers, and the 5000s were designed after the DECstation 3100/2100 series. Actually we MIGHT have caught the issue with the serial port for the DECstation 3100/2100 because I brought up the issue in a hardware meeting and was assured that it had been fixed because (and I can still hear this person's voice in my head) the DECstation was a REAL UNIX MACHINE. I should have found that person later and beaten him to death. David: > Actually, Cutler was already in trouble with management because of the > Prism project.

I will not comment on Dave's skills as an administrator or manager of the project. I do know that he had the very ambitious project of doing the next-generation architecture and the next generation operating system. He wanted a micro-kernel based system with "personalities", one personality being VMS and the other personality being Unix. One issue he had was when there was a clash between personalities he would always favor VMS and therefore the Unix personality would not be "perfect". I felt this was a mistake, since Unix people did not tolerate things that did not smell like Unix. VMS people could have been led over to a new environment over time since DEC controlled the path with VMS. The reason I know this is that I personally interviewed with David Cutler for the position of Unix Product Manager for his new operating system. The interview was going fine until I tried to explain to Dave why his strategy was wrong and he had to make the Unix side really compatible. Then things got ugly, as David really did not like to be told he was wrong. Ken did have the bad habit of cutting off Dave's development money, then giving it back to him again. I seem to remember that Dave was still going full steam ahead while the PMAX was being developed, which is one reason why he was caught so flat-footed when PMAX was announced. It was kept REALLY SECRET. It probably did not help that Ken reportedly asked David in a gleeful tone if the new chip would be as fast as the PMAX.... "Will it be THIS FAST, Dave?" was the reported question. It is also my belief that the Alpha chip came directly from Dave's work on the PRISM, and that Windows NT came directly from David's work on the microkernel with personalities. DEC never "decided to go with MIPS" except as a stop-gap measure for Unix. If DEC had "decided to go with MIPS" they would have ported VMS to it, and since that never happened, it was obvious that DEC had not embraced MIPS. md On Sat, Jul 6, 2024 at 3:27 PM John Stoffel <john(a)stoffel.org> wrote: > >>>>> "Jon" == Jon \"maddog\" Hall via WLUG <wlug(a)lists.wlug.org> writes: > > > The DECstation 3100 (aka the PMAX) was a system based on the same > > motherboard as the VAXstation 3100, except with a MIPS processor. > > It was the first time that Digital had built a system using another > > company's chip architecture. > > That's an interesting statement.

Prism was the first try at building a RISC machine (this was in the 1985-1986 time frame) and it was managed by Dave Cutler. Unfortunately, Dave was not a good administrator. He was doing a very bad job of managing the project and doing a very bad job of keeping management up to date on what was going on. Finally, management cancelled Prism and that is when they decided to go with the MIPS architecture. Dave was trying to rehabilitate himself but the DECStation 3100 basically yanked the rug from under him -- among other things. The adoption of the MIPS architecture caused a lot of grumbling and unhappiness with the troops because of the NIH factor. This in turn allowed Bob Palmer and others to push for a new try at a RISC architecture and thus the Alpha was born. Unfortunately, Alpha took up a lot of resources (hardware design, software, semiconductor) that should have been used elsewhere - e.g., Concentrate of MIPS for high end and intel or motorola for the low end, Ultrix instead of OSF, etc. The Hudson facility (along with disk drives) was a real money sink. Bob Palmer came from the manufacturing side and I think he loathed dismantling DECs vertical integration. When the board of directors told him to preserve shareholder equity, he then started to sell off pieces of the company which started dismantling the vertical integration. But then it was too late. -David

Re: DECStation 3100 on a RPi2040...

by Jon "maddog" Hall

The DECstation 3100 (aka the PMAX) was a system based on the same motherboard as the VAXstation 3100, except with a MIPS processor. It was the first time that Digital had built a system using another company's chip architecture. We had a choice between supporting the MIPS R2000 chip as "big endian" or "little endian". We chose to support "little endian" to be compatible with PDP-11s, VAXen and Intel chips, rather than be compatible with other manufacturers. This, in my mind, was very important since it let us share data over NFS and give greater compatibility with programs and libraries of applications already running on other Unix-like systems such as Ultrix, BSD, etc. Sun experienced this grief when they ported Solaris off the big endian Motorola and SPARC chips to little endian Intel. One of the few issues of the DECstation 3100 (and 2100, known as the "PMIN" after that) was that the serial I/O port did not support hardware handshaking. To save a couple of pennies per system the VAX hardware designers determined that having full hardware modem control (DECstandard 52) on the board was not needed, because "very few workstation users hook a modem up to their serial line". What they meant was that "very few VMS workstation users hooked a modem up to their serial line", opting for DECnet to handle their networking. Therefore the pins necessary to support hardware modem control were missing from the DECstation product lines. Unix users, on the other hand, often had modems hooked up to their workstation, to handle cu(1), uucp(1) and other serial line protocols. We eventually got around this by better refining software modem control, but it was painful. The proposal, design and release of the DECstation 3100 was a top-secret project inside of DEC, kept secret from even many people in the Digital Unix group in Nashua, New Hampshire. The development of the system was done in Palo Alto's WorkStation Engineering group and the software engineering was done in the Western Software Labs in Palo Alto, albeit by taking key engineers from the Nashua facility and transplanting them temporarily to Palo Alto. The implementation was kept so secret that it caught Dave Cutler, then working on DEC's next-generation operating system and chips, by surprise when it debuted at a Board Meeting in Maynard, Massachusetts. Shortly after that board meeting Mr. Cutler left Digital and moved (with some of his team) to Microsoft. The DECstations only were manufactured for a couple of years, as the DEC Alpha processor replaced MIPS in Digital's lineup. Although originally promised that OSF/1 would be ported to the DECstation line, this port was dropped due to realizing that there would never be an application base to support the customers of a DECstation OSF/1 port. It was better for ISVs and customers to maintain the Ultrix base for the DECstations than to split the base into Ultrix and OSF/1. md On Fri, Jul 5, 2024 at 9:02 AM John Stoffel via WLUG <wlug(a)lists.wlug.org> wrote: > > My first real Unix workstation, reduced. > > https://github.com/rscott2049/DECstation2040 > > This brings back memories.

Sadly I only went to You Do it once and it was really amazing. It was before the pandemic in their full glory.

He was in there all the time and immediately was greeted by a sales guy who dove right into a deep conversation about dipole yaggi's, etc. I wandered the aisles, just amazed. They had a pretty decent 3d printing corner as well. Sadly, I think the market for building your own electronics is continuously shrinking. Tim.

Keeping your package manager happy in Ubuntu and Debian -- from prior upgrade discussion

I'm coming late to this discussion; sorry about that. Re: "old packages from a previous upgrade" ... in Ubuntu, the "do-release-upgrade" script is supposed to clear those out. But if do-release-upgrade crashes out, people can get lost as they don't know how to duke it out with the package manager. My standard "update the software" in Ubuntu/Debian looks for deletable and orphan packages specifically. Nuking orphan stuff and removing old cruft beforehand, is THE WAY to make your upgrades work better. The only other source of complication is old additional software repos in /etc/apt/sources.list.d/[...] which are NOT supported in the OS release you're upgrading INTO. Does your package manager want you to delete stuff? dpkg -l | grep '^r' | awk '{print $2}' | sort | fmt ... this command should return no output if your system is clean. Does your machine harbor software not attached to any software repo? (these are AKA "Obsolete packages") Learn the shocking truth: aptitude show '~o' | grep Package | awk '{print $2}' | sort | fmt ... this command should also produce no output on a happy machine, other than perhaps one-shot .deb files installed from downloads (i.e., if you download the zoom client by hand and install that without using a repo, etc). The more cruft, the worse your major-version-upgrade experience will be. The upgrade is performed entirely by the package manager, so that part of your OS needs to be happy before you can start an upgrade with confidence. --MCV.

Was last in you-do-it May 17 when travels took me nearby. Store was about 80 percent empty then. Sign of the times. Going forward we all plan weeks ahead with free shipping things from China.
