lets devolope a seti crack rack

what will we need?

I had an idea about bootable linux on CD buffered to ram and work units saved to disk... so all you need is mobo, ram, floppy, cdrom, network card, vid card (temp)
 
You should be able to do it without the cd-rom.

I saw these two sites on Sukhoi's site.
Diskless Seti Box
Another Site

I have been meaning to try it, but haven't had the chance until I upgraded my dad's Athlon 1300 so now I have a 1300, Motherboard, 384MB PC133 SDRAM, 10/100 Ethernet Card, and InWin Mid Tower w/300 Watt. All I need is the video card and floppy. So as soon as things get back to normal from the holidays, I am going to try to put it together.
 
I beat diskless SETI to death - or rather, it beat me.

I ended up just running Win98 on them. Cheap old HDD.
Works great, no headaches.

But... if you can pull it off... my hats off to ya Narzy! 😀

helll I dont even know where to start :Q, where is kilowatt?
 
been there... done that. Too much stuff to fit.

[edit]
I don't mean to be negative... it just was a real booger.
I must have tried 4 different versions, ended up needing a CD.
I figured heck, I'll just get some cheapo HDD's and run 98.
Loaded from CD to HDD and then just moved the CD to the next node.

It's not real elegant, but it works.
 
i wonder if its possible to run the cli off a dos disk... i think i'll go try in a bit.
 
will the cli run in native dos? If it will, you could have one box as the setiq thing and have x number of shared folders where x = the number of extra boxes you have and have the extra boxes boot up to dos tcpip boot disk and mount one of the shares as its hard drive. people say that running from a ramdrive doesnt improve performance, so I assume running from a network drive wont decrease it? This way you only need NICs and floppy drives and one hard drive. Just an idea, I dont know much about Seti so I may be WAY off, but this was my plan for my ECCP rack when I started ECCP last monday, but unfortunantly ECCP wont run from true DOS. I even tried mounting a network drive from DOS and installing windows 95 to the network drive, but it would drop the connection when it would initialize the NIC in 95. 🙁 McOwen suggested I try 98 so that will be my next step. So in essence when I am done I will have a 40 gig harddrive being the primary drive for ~10 systems.

The easiest way to do diskless Seti i think is as follows:

1) Klinux, but with support for NFS or SAMBA.
2) Server with space on a big hard drive for each client computer.

Mount the network drive on boot, and run Seti. Seems pretty easy to me.. 🙂
 
You can't run the CLI from DOS. You need Linux or Windows.

The HDD on a multi-node server really doesn't have to be that big considering you'd only need maybe 200 MB max per partition per node.
 
I agree with DanC. I just use Win98. An old 500 MB HD can hold an installation of Win98, all cab/setup files, and still have enough room for all the DC projects - you don't even need a floppy disk.
 
There are people selling 500-1.0 gig hd's in fs/ft for like $20 some times. I always grab one or two when I see them for cracking / Net machines.
 
herm...willing to let them go GWN? its for a noble cause, after the race I will certainly use them for ROCK...
 
hey narzy, at my work, we throw away like 50 1gig drives/month from comps we've been upgrading.
i can probably get you some.
 
Narzy, why don't you get those HD's from Warrior X, (shouldn't cost too much to ship a box full UPS), then resell them to us for a "fair" price, proceeds to benefit ROCK?

I took the same route as DanC and installed Windows on 2 old hard drives for my rack, but one of them has some bad sectors and will die eventually. It would be nice to have a cheap spare or two.
 
Hmmm,
Maybe it's time to resurrect the old crack rack. With Upgrades of course..... 😀

It's times like these I really appeciate the dnet clients, with the ability to install itself as a service, to buffer WUs, to tunnel firewalls, AND in this case to allow the client to fetch/flush WUs from a different directory (ie network drive) and the remote buffers option. 🙂

Although, now that I think about it,
Has anyone tried putting the clients on 1 network shared drive, mapping the network drive for each node, then running the SETI client from the node?

Let's see,
1. You would need 1 "server" node to run SETI, VNCVIEWER (or similar), a fast hard drive with more than enough disk space to hold all client's SETI folders.
2. Each node would have MB, CPU, RAM, FLOPPY, P/S, NIC
3. Node Operating System? Linux on floppy? Not knowing Linux, I'm assuming you can "map" a network drive similar to Windows OS.
4. Hub with enough ports for all nodes, server, and uplink to Internet connection or the rest of the network, cat-5 cables
5. One monitor, keyboard, mouse (or mouse on each, depending on if you can disable mouse in MB or OS) OR KVM switches if you don't want to be switching the cabling around, but after setup, it shouldn't be needed
6. For best uptime, a UPS(s) for the nodes

Then setup the "server" node, with SETIQ, VNCViewer, and the SETI directories. You could get each one started with a WU on the server, and have it configured the way you want.
SETUP a node SETI1, with VNCServer, NIC, hard coded IP address (or dchcp if network setup that way). Question is will Linux and VNCServer fit on 1 floppy? Could setup a RAM drive to run SETI from, since the hard drive access will be on the "server" hard drive and not the RAM drive. Execute SETI from that node's SERVER folder.

Each node would have to have it's own "startup floppy, with the IP address, the Network drive mapping set to it's own SETI folder on the server, then execute VNCServer, and SETI.

Once setup so the floppy will start the node automatically upon boot, shut down, unhook monitor, keyboard, etc., startup the node, check status on the "server" , then move on to the next one.

Obviously, quite a few details missing, but even if you had to use several floppies, once it was setup, restarts should be fairly quick once automated.

And, a lot of this is based on little or no knowledge of Linux, except for using Klinux, so I know at least some if not most of it is possible.

And I'm basically thinking "out loud" so to type. 😉😉

And, for the amount of time it would take me to figure out Linux and get it setup, it would probably be worth it to just grab a few cheapo hard drives.....😉😉😉
 
Maybe not the fastest idea, but can't Windows actually be booted off a mapped network drive? Then all you'd need is a fairly easy to create DOS network bootable floppy.
 
don't know about win98, but win98lite I think is able to boot
off a mapped drive. although I've never tried to run seti off
that OS.
 
98lite/98micro isn't any different than regular 98 really..it just cuts some of the junk out. So if 98like can boot from a mapped drive, than 98 should be able to also. I believe I remember reading that you need to change something in the msdos.sys of the Win98 installation to let it boot from DOS.
 
Wouldn't it run a bit faster on 95 than 98? Less junk to load? Or would 98 be supperior as it fixes millions of bugs...GL with this project, i would if i had the extra stuff laying around(actually i do have some stuff, i'll make a list in a bit and see if anyone can make a setibox out of it)
 
from what I understand the linux client is a bit faster. (if you dont load Xserver and Xwindows.)
