<0> if it's detached you can't get it back, unless it's in a screen or something
<0> LSzilard: you can't get the same shell back on re-login
<1> OldMonk: crap.
<1> OldMonk: the same 'shell session', you mean, of course
<0> yeah
<1> he should have put it that way
<1> OldMonk: and the most interesting question he asked (i thought) was: "would you personally be proud of the fact that a Unix system that you managed reported an uptime of 6 months?"
<1> OldMonk: i said: "it depends")
<0> on what?
<1> OldMonk: my response was:: "it depends on what is the system's mission in life? is it an app server? is it running a critical Oracle database, or something? Probably not. Is it a webserver? Then, yes...possibly. But you need to constantly be on top of OS patches, kernel parameters tuning, that kind of thing, which requires reboots"
<1> OldMonk: he said i basically nailed it
<1> i've heard of cases of a BSD server at Berkeley running uninterrupted for 2 and a half years uptime.
<1> that's 900+ days uptime.
<2> I had a 586-133 (Overclocked to 160) that had just over a year of uptime as my dialup NAT box.
<2> ...the secret to her uptime? Sealed lead acids in the power supply.
<1> CancerMan: good ol' AMD 5x86-133.
<3> holy cow
<2> *nod* Reliable as hell.
<1> CancerMan: man, do I have stories about what I did with that box.
<3> a yr of uptime
<1> CancerMan: this was back in 1997 - '98 -- running RH 5.1
<4> no ups ..
<4> 21:13:26 up 291 days, 1:44, 18 users, load average: 0.08, 0.03, 0.01
<5> yay, it looks like this violin is going to be easy to return to use
<1> CancerMan: it was originally an IBM PS/3 Model 30-286 -
<2> *nod* I was running Slack 3.3.
<2> PS/3?
<4> my intel machines have croaked twice from power gliches
<1> CancerMan: hehehehe......no. 32-bit. Not 128.
<1> CancerMan: it gets better.
<2> I actually have an IBM server processor...
<1> CancerMan: i had 64 MB 70ns ECC / parity DRAM in it -
<2> ...it's a 486SLC soldered onto a board designed to shove a 386SX into a 286 PGA socket.
<2> What was this box doing originally?
<1> CancerMan: but the MMU on the mobo supported paging / interleaving, and 90% of the time, the random R/W access on the 64 MB of RAM was around *30ns*.
<1> CancerMan: not PLCC?
<1> CancerMan: I also ran Enlightenment .9X something or other on it -- the mobo had 1 MB of Cirrus Vesa LocalBus video on it, that ran at 33 MB/sec
<2> The 486 was intended for PLCC or surface mount, but it was the PGA version of the 286.... I don't think they could have had that board (which was the size of a P-Pro) with a PGA adapter.
<1> CancerMan: it was our network's DNS server, an FTP server, an Apache server, and it also hosted serveral users -- i remember using this little IBM PS/2 pizza box --- and running GIMP --- and watching how it was doing - it never even broke into a sweat.
<2> Ack. I had E16 (or 15?) on my first pentium. Slow slow slow.
<1> CancerMan: it was like: "bring it on!"
<2> I actually HAVE a PS/2 486 DX4-100 still... Although I've told myself that it's not worth messing with.
<2> ...not to mention that it's SCSI, and SCSI is just 'spensive compaired to anything else you can yet.
<2> s/yet/get
<6> CancerMan: i got a c64
<2> Oh bah. Who DOSN'T have a C=64. :P
<5> <--
<2> Oh. Want one?
<2> It dosn't boot, but you can always Mini-ITX it.
<7> I don't, but I have 2 C128's. :)
<1> CancerMan: the only thing that ****ed was that the Reply motherboard had a an (IBM-imposed) legacy 8-bit XT IDE interface on the motherboard -- and even with a then 1998 screamin' hot Quantum Fireball 504 MB drive doing DMA1, it still only got 1.6 MB/sec.
<1> CancerMan: ....and that was with all of the over-the-top HDPARM settings tweaked to the max.
<2> LSzilard: Nasty. The network interface was faster than that.
<5> my network interface has always been faster than my disks...
<1> CancerMan: 16.4 MB/sec, 16-bit ISA-bus. Not MicrocChannel
<2> Lozvare: I want a 128D... It would look great next to my Apple IIgs.
<2> LSz: You had a PS/2 without MCA? W.T.F. ?
<1> CancerMan: er...."MicroChannel", even.
<1> CancerMan: Yup.
<7> CancerMan: One of mine is a 128D
<2> I didn't know they eve MADE that.
<2> Lozvare: *nod* You officially ****. :D
<1> CancerMan: It started out as a pure IBM model 339 / AT-based '286 system.
<7> CancerMan: Looks good next to my Amiga 3000/25
<1> CancerMan: 16-bit bus.
<1> CancerMan: But the CPU was an AMD 5x86-133.
<2> LSzilard: Heh. IBM and Apple both had some pretty funk nasty system boards.
<1> CancerMan: And the motherboard supported 64 MB of 70ns ECC/parity.
<1> CancerMan: but, again, the MMU ("memory management unit") on the motherboard supported paging and interleaving, so long as both banks were the same size & speed.
<2> *nod* I know what an MMU is. :P
<8> The IIgs was a rather nifty machine, I thought
<1> CancerMan: i had 2 32 MB DIMMS, running at 70ns, but I ran the Byte Linux benchmarks on the sumbeeyotch, and they showed *31 nanoseconds, sustained random read/writes, all the way out to 64 MB.
<6> CancerMan: how old are you anyway?
<2> The IIgs WAS a nifty machine. However, some of the later M68030 machines did some crazy ****.
<2> 27.
<6> hm
<1> CancerMan: so, for all intents and purposes, it was as if I had *64 MEGABYTES of 31ns L2 CACHE* -- and guess what. There was no provision for an L2 cache on the motherboard.
<1> CancerMan: well.....90% of the time, anyway
<1> CancerMan: all in the original little IBM PS/2 pizza box.
<8> CancerMan: I mean, the thing had two processors in it - one for IIgs apps, one for Apple II emulation.
<5> zetawoof, er?
<5> zetawoof, as I understood it, the 68C816 was capable of running in both modes?
<1> CancerMan: As I said, I ran Enlightenment at 640x480x32 bit color -- and also 1024x768x8.
<2> LSzilard: I wonder what the magic was... I thought the chip needed 70ns for the data lines to become valid after the final RAS set.
<8> Liandrin: Perhaps I'm mistaken...
<5> the C=128 had two CPUs, one 8502 and one Z80
<8> Liandrin: Yeah, I must have been thinking of something else.
<2> zetawoof: The C128 had 2 processors.... a 6510 for C64 emulation, and then a Z80 to run CP/M. The IIgs had a 6502 emulation mode.
<2> zetawoof: Oh.... and the C128 CP/M... The low level I/O routines actually ran on the 6510... which would have been super-kick-*** if both processors ran at the same time.
<2> 8502?
<2> I know the C64 ran the 6510... However 8502 sounds familliar.
<5> maybe it was 8510
<1> CancerMan: you got me.
<2> Oh... Yes... 8502.. It's on 'da web'.
<2> 2MHz 8502 of all things.
<1> CancerMan: but the best sustained random read-writes I could get off Quantum Fireball or WesterDig drives was 1.6 MB/sec.
<7> CancerMan: It only ran at 2MHz in 80 column mode
<6> heh c64 ran at like .99MHz
<1> CancerMan: it also kind of pissed me off that the onboard 1MB of Cirrus Logic 5428 Vesa Local Bus chip wouldn't run at the AMD 5x86's core speed. It was stuck at 33 MHz.
<1> CancerMan: and the core speed of the AMD 5x86 was 133 MHz
<2> LSzilard: Nashteh. It sounds like it was a slow machine, but reliable.
<2> Well, didn't ALL those 486ish machines run at a top FSB of 33MHz?
<1> CancerMan: oh, it *slaughtered* a LOT of 2nd generation Pentium 75's and 90 Mhz machines, on the Byte Linux benchmarks - very comprehensive.
<1> CancerMan: even on some of the raw EIDE disk I/O
<2> Lozvare: Heh... However, an Apple II with a transwarp could kick it's ***, I'm sure.
<1> CancerMan: Byte Magazine's Linux benchmarks.
<1> CancerMan: i think the clock on the Vesa Local Bus was locked in at 33 MHz
<1> CancerMan: which was too bad.
<1> ..and it even spec'ed out at VLB 2.0 conformance
<1> CancerMan: wanna hear something scary? In 2002, I loaded and ran Sun Solaris x86 7.0 on this pig, and it ran p***ably well.
<2> LSzilard: I remember the multiplier for the 486DX4-100 was 3... meaning the FSB was really 33MHz... 133? 4... same thing.
<2> Ack!
<4> my 5x86-133 had both pci and vlb. reliable for years after i pulled out the buggy cache chip and disabled it.
<2> I still can't beleive you had a standards compliant PS/2. Sure it wasn't a PS/1?
<2> Lozvare: The Z80 is still produced.
<2> ....for embedded applications.
<7> CancerMan: Yeah, like my TI-85 calculator
<4> i ran it for three years of so then gave it to a daughter who used it for two more.
<1> CancerMan: i'll tell you something: the subjective "command-and-response" "feel" of my little, tweaked IBM PS/2 30-286 pizza box, with the guts of a kick*** Reply Corporation (Cupertino, CA) motherboard solution bested a 24-bit Sun Sparc 5, and even a Sparc 20, in some cases.
<1> running Solaris 2.5.1
<2> white: I still have my 586, however, I can't see much use in it, and am going to chunk it. The power supply is the only part I'm planning on keeping.
<1> CancerMan: this thing had the exact same PS/2 pizza-box case & power supply as the original IBM PS/2 Model 30-286. It was the ultimate sleeper.
<2> *nod* Reply Corporation... Hrm.
<1> CancerMan: I stuck the green "Linux Inside" sticker on it.
<2> So it was an aftermarket board...
<1> CancerMan: Oh. Reply is long gone.
<1> CancerMan: Yup.
<2> Ahh... That explains the ISA/VLB stuff.
<1> CancerMan: But they were in bed with IBM and Apple, for CPU daughter cards.
<2> *nod*
<2> Go figure.
<4> CancerMan: i have mine also along with three fine at cases. but yeah, they're hitting the recycle soon. along with a bunch of isa/vlb cards ans under 1gig drives i still have laying around
<1> CancerMan: Reply made an x86 Apple 950 solution, hosted on the bus
<1> Quadra 950
<1> CancerMan: it was a fully working i486 100 daugher card for the Quadra 800 - 950, that ran on the NuBus.
<1> hell ----
<1> i've seen some amazing stuff done on an old Pentium 90 and 120, with a full MCA VM/390 daughtercard running RedHat.
<1> "MCA" = "MicroChannel Architecture"
<1> by that time, around 1997, MCA was running around 140 MB/sec on the backplane
<1> sustained
<1> (and very quiet TTL noise levels, of course)
<1> with bursts around 640 MB/sec
<1> CancerMan: Ever hear of an Intel i860 "Wizard"?
<1> or even the i960?
<1> dates back to 1986 - 1988
