Ive checked out TACUBE.COM but I dont understand the crack rack

Each node consists of the following:

Motherboard
CPU
32MB RAM
Network card
Video card
Floppy drive
Power supply

Nodes are booted off the floppy drive using a Linux distro, mostly Klinux, but a few are still running Freesco. The client is run in RAM, and each node is mapped to the pproxy on the server where it fetches and flushes blocks. The pproxy on the server connects to Dnet.

Rack #1 is 13 nodes, plus the server. Rack #2 will be 10 nodes.

So you run RC5 off the Floppy's, then use the network card to link to the internet connection??

How you get the parts??

And like you just have them lying next to eachother and not in cases??

P.S. I'm thinking about putting a small rack together and using a hub to run them through my cable modem (Can I do that without paying the extra 5 bucks Time Warner wants to charge me>?)
 


<< then use the network card to link to the internet connection >>



No, the NICs are plugged in to daisy-chained 10/100 switches, which are uplinked to a Linksys DSL router that hands out the address to each NIC using DHCP. They fetch and flush to the pproxy on my server which, in turn, fetches and flushes to dnet's keyservers.

Look at the pictures.

I suppose &quot;complicated&quot; lies in the eyes of the beholder. I'm guessing no one here was born with all that specialized knowledge, but if you are interested and lurk around, read the posts, ask questions as you did, you'll pick up on it.

I don't know jacksh!t about distributed computing, pproxies,

<< a Linux distro, mostly Klinux--WTF is that???? >>

, but I suppose I will pick up on it over time.

Main thing is whether it is ultimately interesting to you, if so all you (we) need to know is available right here.

It seems complicated at first, but the nice thing about this forum is that it's packed with gurus who helped me beat it in to submission.😀

Naka2 -
That's (squared as in Naka-Naka) -
Russ was a complete newbie, not that long ago.

You can do this! - If I, as a die-hard NT geek, can do Linux, you can do a crack-rack.

I'm so ate up on this stuff, I'm writing to this forum from Santiago, Chile at the moment. Can't let go of it....

JimMc,

Klinux is a single floppy Linux distribution that includes the dnet client, and was developed by our very own Kilowatt.🙂 I'm switching over to it from Freesco, which is also a single floppy distro, but does not include the client and thus requires the use of two disks.

Also, Klinux is MUCH easier to use than Freesco.

Russ, NCNE
 
Russ,
I'm not so sure it's luck, but maybe sheer stubborness as in refusal to let a dumb machine get the better of you? 😉<-----friendly wink

So your saying that you dont need a Hard Drive or anything and you get it to load everything off the Floppy???

How you do that.
 
get someone like kilowatt or Ccalvert, who are linux guru's, to create their own &quot;mini-linux.&quot; stick only the things you need to crack from linux onto a disk. No HD involved 😉
 
Well NakaNaka, You know how you can bootup DOS off a floppy?
Once booted, you are running a small version of DOS, that can access the HDD, CDRom (If enabled) and do certain things.

For &quot;Crack Rack&quot; systems, you boot off a floppy, with a minimal OS, and the dnet client, because all we want the &quot;Rack&quot; to do is Crack Dnet.
It'll help, if that minimal OS has networking support so you don't need to worry about swapping floppies, and/or flushing the dnet client on another machine.
Most (I would think) are running a &quot;Server&quot; on that network, with a Dnet PProxy, acting as their own &quot;Mini keyserver&quot; for the &quot;Rack&quot; boxes to flush/fetch more blocks to.
The Dnet PProxy then passes those blocks onto Dnet or the &quot;TA Round Robin Proxies&quot;.

No need for a HDD, unless maybe you were building a &quot;Beowulf&quot; system, but that's a whole other story.
 
I really admire Russ his CrackRacks (tm). I don't have much of the hardware Russ has, but I'm considering building a small 'experimental' &quot;crackrack&quot; myself.

It would seem attractive to use the DOS-client for RC5 on the rack because it's the fastest client around, but of course then you'll have to solve the problem of the poor networking abilities of DOS. Serial connections are fast enough and is well implemented in DOS, but having multiple serial connections is a 'no-no', because serial connections slow down RC5 a whole lot, because they require CPU intervention. So the only solution seems a LAN. A LAN in DOS is hard to implement, because as far as I know DOS doesn't have any LAN support by itself (which makes sharing input- and output-buffers very difficult). It would require installing something like WINSOCK for DOS, or not?

Maybe I'd better resort to assimilating schools, universities and companies until I find the time to get my personal crackrack... 🙂

Good luck in your activities!

Mooooooooooooooh!
