I probably won't follow you back, in order to protect this poor machine. Follow one of my other accounts, and I might return the follow there. :)

The ol' 486 has also been upgraded to 11.0-RC2. It's frankly amazing this thing still holds together.

    @ltning Wow, 128MB of RAM on a 486. I bet that's a huge part of how it's doing as much as it's doing. 😆

      Yeah. Having RAM helps. But only half of that RAM is even cached ;) I should find a similar board that has 1MB cache.

      Worth mentioning I have NetBSD running on 16MB as well, but I'm not going to run any kind of server on that. ;)

              Mhhh.. crashes when it start's in my Dual Pentium II system. It's performing at start a heavy job "started deferred data integrity check", which does lot IO.
              When I turn off the traffic from outside, it seems to run (takes ages). But when I turn on the traffic to it, it crashes with
              `Illegal instruction (core dumped)`

              I took the installation over from the PIII system and activated the MP kernel. (Do you really have to cp it from the CD by yourself??)

                Recent versions of OpenBSD automatically install the right kernel. Are you running a fairly recent version?

                  @FritzAdalis 7.8 downloaded the iso two weeks ago.
                  I took the SSD over from an P III single core system, where I installed it. I thought OpenBSD should be capable as well to get swapped around similar hardware.

                    Usually it can. I'm not sure of the technical reasons for having single vs. multi processor kernels any more, but they should at least boot.

                    (I guess I read what you wrote backwards from what you meant.)

                      Looks like I have to do some more debugging.

                        Yeah, it shouldn't crash. Maybe try ktrace/kdump on it and see where it dies, or gdb on the core file if you know how to use it. (I do not.)

                          @FritzAdalis I tried ktrace+kdump but didnt get something out of it. At the end, it gets a SIGILL, after trying to read a json file. I then did a dump with tracing all childs and saw it seemed to read a lot of certificates - so I assume it's doing some SSL stuff and fails there (?) 🤷

                              @FritzAdalis Idk - @ltning is running two servers on similar machines, one with AMD 5x86 and one with dual Pentium on NetBSD. He's also running a patched version, but from what I understood (C programming noob) there was nothing directly ssl related in those commits.
                              I'll try this fork next just for fun.

                                @[email protected] @[email protected] I'm currently running the regular version - but on NetBSD, not OpenBSD. Are you building it yourself? Is it possible it links to some system library that is compiled with SSE? But it looks like the SIGILL is in the stat system call which is weird? Or am I misreading that?

                                  Hm, Pentium and 5x86 wouldn't have any instructions that a PII doesn't. Could be something that was ripped out of libressl but netbsd is I think still on openssl. Or I'm completely off base and it's just a regular bug.

                                    Yeah, but if the binary was built on the PIII, then it will not work on the PII assuming the compiler uses "current machine" as default target..

                                      OpenBSD source will always output the same code independent of the current cpu capabilities, but other code may not.

                                          NetBSD is likely to be a fair bit faster than OpenBSD - especially on such old hardware, where most of the various CPU vulnerability mitigations are useless but OpenBSD enables them anyway. T(h)rashing of caches and pipelines for no good reason makes for a suboptimal experience.

                                          You may want to make sure you disable encrypted swap unless you have a ton of RAM. Someone seems to think that if you're on x86 you always have CPU to spare for encryption :D

                                          Also, pkgin is fantastic and many (more than on OpenBSD) packages are built so they work on even an i486.
