Yay! Or maybe AIEEE! Seems like I'm giving a talk at #EuroBSDCon again this year!

Anyone who has been following me here for a while will know I'm a hopeless #retrocomputing nerd, and I will make no attempt at hiding it during my talk:

Dirty Tricks: Using nginx and Lua to thwart bots and skript kiddies

I'll (try to) show how you can protect your #BBS from drive-by portscans and your production systems from #DDoS attacks using all the wrong tools.

Dietary warning: may contain traces of floppies.

Okay, manchmal hat man auch mal Glück. Ich hatte vor Jahren meine Version der Data Becker "Goldene Serie" Fassung von "Doors!" verschnipselt um sie digital einzuscannen. "Doors!" war mal eine alte OS-Erweiterung für Windows 3.1. Hatte danach jahrelang nach einem Ersatz gesucht, aber nie was Vernünftiges gefunden.

Jetzt hat gestern plötzlich jemand einen ganzen Haufen dieser kleinen Bücher fast schon kostenlos auf eBay eingestellt. 4,00 EUR inkl. Versand?! Und alle noch original verschweißt. Musste natürlich sofort zuschlagen! Also, nicht nur Doors!, aber eben auch. ^^

Great, all four cards are working perfectly. 🙂

With the AlphaStations, I also got two spare 9.1 GB hard disks. Tested them and both booted right into Windows NT 4.0 SP5. Saves me quite a bit of work. 🥳

btw, speed is phenomenal. You are on the desktop in about 30 seconds after POST is complete. And it feels very snappy.

Now cleaning the case parts. The front drive doors all look nice except for one, which has tons of scratches from someone in the past trying to remove a large label. But I assume at least one #AlphaStation will be a parts-only machine anyway. So getting four good-looking ones is sufficient. 🙂

@PurpleJillybeans Another vote for OS/2, but do some homework ahead of time to figure out where to get drivers and FixPacks. I ran OS/2 2.11 on a 486 and on an early Pentium years ago, then I upgraded to OS/2 Warp. I had to choose my hardware carefully to ensure proper driver support.

Windows 95 and 98 were mediocre in comparison, but I never had to worry about hardware drivers.

#retrocomputing

This is hastur.retro.lan, one of my three retro PC desktops. Nominally I call it my DOS/WfW311 PC, but it has an external CF bracket so I can switch OSs easily. Right now I have one card with DOS/Win3 on it, and another with Win95. I was running an old Linux distro on it but decided to move that to a VM.

Any ideas for another OS to try? Something that'd run well on ca. 1997 hardware, and with a lot of fun uses.

A vintage PC in a beige tower case. A Sony DVD-RW drive and internal ZIP drive take two of the three 5.25" bays, while the 3.5" bays are taken by a Gotek floppy emulator and a real 3.5" drive (which sadly doesn't work very well). A navy blue case badge indicates that the case was originally used for a Telekol Integra-X telephone system. A silver and black USB sound interface is sitting atop the case, used to capture audio for streaming.

For any #MTCP, #DOS and #Retrocomputing nerds out there who are also running httpserv and want pretty graphs, poke me for a recipe for a hideosly bloated #logstash configuration to ingest the UDP logs.

I feed it to #Graylog which stores the data in #Opensearch - a pipeline that combined (and this is accurate) needs, conservatively, 4096 times as much RAM as the floppy museum itself (8MB).

And while looking at this when making this screenshot: I wonder why someone would hit http//floppy.museum with a Referer-header indicating they come from a salesforce-dot-com address? http-colon-slashslash-136.146.46.127 (about halfway down the list).

This list contains timestamp, which museum server handled the request, the remote IP, the country code of the remote IP, the path requested, and the Referer, if any.

@cr1901 I'm a packrat so I know I have it here somewhere. The hard part is remembering if it was a diskette or a CD-ROM.

It turns out I was looking for a CD-ROM when it was on diskette. And the drivers that I tried to download and use were for a later hardware revision, so they refused to install.

When I did get the right drivers, it then demanded the WIN98 install CD-ROM. So I had to pray the drive was still working.

1.5 hours later it is done ...

#retrocomputing

I hate how Win98 handles device drivers.

"I see you've previously used this card for 25 years, but you removed it for a few minutes and now I'm going to make you reinstall the drivers from scratch. Please find the diskette or CD ROM from 25 years ago, and nothing will work until you do. Thank you for your attention to this matter."

DOStodon starts, it feels VERY slow when fetching network data and apparently liballegro and the ATI Mach64 graphics card are not the best friends.

This is MIT-MC.ARPA, currently in preservation. While it may not be necessary to run all of its subsystems, we might be able to bring up the 3 bay KL10 CPU and Front End processor and emulate the rest.

Turns out Netscape 2.02 is too easy, so in this picture is IBM WebExplorer v1.1h running on OS/2 Warp Connect. Using the magic "work area" feature of folders (mark a folder as a work area to have the OS manage objects within it as a kind of unit), I can open several windows at once. True multi-process browsing 😉

Anyway, I've reduced my ambitions ever so slightly, and am now in the process of installing NetBSD (-CURRENT) on what is essentially a 386SX-class machine: 16-bit bus, 24-bit addressing, 16MB RAM, and nearly as unpleasantly slow as the 286 I had planned to use. It is however equipped with an IBM-branded 486SLC, which is from the Blue Lightning series. This one definitely has a full 486 instruction set. More hardware details will follow when I've completed the build (and installation).

Meanwhile, the obligatory screenshot from the installer. Note the ETA for simply unpacking base.tgz ..

(In other news, the #snac instance on this poor Pentium Pro server is sweating hard whenever I post something. So let me know at @ltning@anduin.net if you have problems receiving/reading my posts. I've made some tweaks but it will be unavoidably detained for a while following each post, my apologies for that..)

The latest mTCP for DOS is available!

This version includes some changes to improve TCP reliability on long running (but idle) connections, black & white Sixel graphics in Telnet, a Telnet emulation bug fix, and other small fixes sprinkled around.

The source code to NetDrive (network attached storage) is also published now - enjoy reading an unholy mix of x86 assembly code talking to Golang over UDP!
