Is the version w/o DHCP enabled available? I DL'd the one from the link just above and it still had DHCP. The systems I was running it on are diskless. It just seemed to be looking for an outside OS to me but I am probably wrong on that :)

I went Russ's route and used Freesco. Thank you Russ for the step by step info.

Now I have aLinux question. Since all my crackers have hard drives, how do I copy the dnet program files from the floppy to the hard drives so I don't have to access the floppy whenever I start up the machines? I already have freesco running on the hard drive, I just want to put Dnet there as well so I can have every thing in one place.

I should point out that the hard drives used on the crackers are very small ie: 80 megs or so which is why I didn't just toss Windows on it. the freesco option or Kilo's option seems to be hte way to go if you have old, tiny HD's lying around. I wonder if my old 10 meg Seagate Winchester drive would be detected and supported by Freesco...hmmmmm....

GGRRRRR!!! :|...I think the problem is with the commpression, saving it to my web space.
Everytime I make a new one on my Linux Box, it works great.
If I download it, and go thru the steps in the README, it gets corrupted.
All that is really booting is the Kernel itself, it's built in.
The Kernel is fine now.
It just has a problem saving the Ramdisk file system in commpression.

I'd go on to something else, and forget about it, except it's got my goat now.
I'll have to lay some WOOP-ASS on it, to show it who's boss here!

HEY! I like the DHCP one.:) All my nodes are connected to my router. The Kilo Distro grabbed the IP and sub and set up the NIC just right. But, I ran in to exactly the same error as Mandrill.

HMMM....That means I'll have to fix Version 1.1 :Q up with the "New Improved Kernel".
That's the one I'm using, it's nice and quick to setup.

Are you running at least 32MB memory on all your nodes?
That's the "Minumim Daily Requirment" as I'm trying to use 16 Ramdisk of 4096K.

I'll try and get it all done this weekend, but I do have some customers to take care of also.

My big problem is compression, but I'm not really gaining much by Zipping or tarballing it.
I think I'll try just leaving it the way it is "Straight out of the oven"
What's a couple more K of download to the dial-up people? :)

OK, I think I have the Dumb-ass compression thing figured out.
(Would you beleive it was all my fault? I didn't think so. ;))

No DHCP right now, but it's on the way.
For Realtec 8029, 8039, Tulip, SMC and NE2000 based nics.

----------------------------------------------------
Tmp down untill I can find some space to store them!
----------------------------------------------------

I'm going to kick out a 3Com version (v 1.3), and than a DHCP version of both, (v 1.4, 1.5 respectivly) and then I'm moving on to a NFS Disk.

<Edit> Use buff-in/out in memory, for better results, and don't go overboard on the number of workunits.
I had it crash with a buff-in/out &amp; a chkfile on the ram disk with 64 ^33 workunits.

Could one of you guys help me with a stoopid newbie Linux question?

I copied Freesco onto my small hard drives using it's nice move2hd command now I want to copy the Dnet files to the hard drive from the floppy so it can be set up perminent like. Gawd I hate bein a newbie

Are you using Remote Buffers?
And If so How?
I can ping between the server and the Klinux box but I can't get any work from it. I think I have the Klinux Dnet setup right so it is a problem with NT4 not allowing access.

I am also going to be using small HardDrives. I have them and don't won't to buy floppy drives. So I'm glad you asked the question about copying to the HD.:) That is going to be something I'll need to know.:D

Kilowatt

Can the config be saved or will I have to reenter the netconfig and Dnetc config everytime I restart?

Thanks

KWatt, once setup and running, everything is in a ramdisk.
If you ever shutdown, or heaven forbid it crashes, you'll have to reconfigure it again.

I've finished working on versions 1.2 and 1.3 without DHCP.

If you guys want a sneak-peek, http://Klinux.homestead.com/.
You'll have to Excuse the crappy free site stuff, I don't have enough space left on my personal site.

I downloaded all of them in WinBlow$ last night, and they all worked OK except the very last one, Klinux-1.3 with DHCP (for 3com cards).
So don't try that one.
Also, I haven't D/Ld and tested in Linux yet, I'm goint to do that today from home.

They seemed to work OK with the Rawrite utility that is now included.

This has kept me fairly busy the last few days, but I'm doing it for CrackHeads everwhere. :)

It'll work for OGR also, so Remember to read the README that's included for more detail.

When setting up the dnet client, it's important to Not use buff-in/out in memory (no disk I/O).
Go ahead and use the ramdisk with buff-in/out.
Don't use checkfile or any logging, space on the ramdisk is limited, and might return error messages, frezzing the client.

Also, I've found 64 workunits seem to work best, and should last a Dually machine about an hour or so.

Let me know what you all think, if I'm on the right track or not.

Kwatt, I was just wondering, you are running a dnet pproxy aren't you?
I don't think it will work right just sharing another client's buffers, maybe it will, but it's not been tested.

If your running a dnet pproxy, do you just have certain ports open?
Don't set ports on the pproxy, unless it's connected to the net full time.

If your running version 1.1, try the &quot;New and Improved&quot; version 1.2 :).

If your NT box is setup for IP masking, and routing, you can go straight to Dnet.

Kilowatt, No i'm not running pproxy. I'm just sharing buffers for now. And the NT box is not set up for anything but cracking. I'm on (gasp) dial-up.:( There is no DSL or cable out here. Heck if I was 1-mile farther out I couldn't even get SUNSHINE.:D

But I now have a copy of &quot;Running Linux&quot; and &quot;Linux Little Black Book&quot;. So, I'll figure out something.

Does anyone know of a linux distribution that does not install a GUI buy default? I've tried to leave out the GUI but I don't know what to skip and it ends up not installing completly.
And I can't boot from the CD on the computer I want to install it on. The manual with SUSE claims to give a choice of leaving it out if you boot from the CD but not if you boot using the floppy. RH requires 500 megs and ManDrake 600 megs and these are the mins. Where is the lean-mean OS I've heard so much about? I'd be using one of the Free DOS's if I could get SMP support.




Thanks for the info though it has started me on a new project.:)


Well I think I'll go make a soup out of these books and see if I can get anything out of it that way.:p

Kwatt, you should be able to run a pproxy on what ever machine you use for the internet (as long as it's on your network)
It doesn't have to be a NT box.

Maybe you could run a small dnet pproxy on it, to supply blocks for the Klinux machine(s), and any others you have.

The pproxy should hold enough workunits to last your &quot;Herd&quot; untill you sign back on to the internet again.
It can even be setup for auto flush/fetch if the .ini file is set right.

That is what Klinux is setup for, running a dnet client over a local network, flush/fetching to a local pproxy to get workunits.

If you need some help getting a pproxy setup, I'll be glad to help out.

I think I'll start a new thread, this is getting to long.
Look for CrackRack for Dummies II, coming soon to a BBS near you.

Kwatt: I am using a pproxy to fetch and flush from. Go ahead and set one up. It is real easy to do. My linux clients fetch and flush to there.

Kilowatt: I am curious as to why you wouldn't buffer in memory only. It would save wear and tear on your floppy drive if that is all you are running it off of. I just have my in buffers set to hold 1 block at a time so any work lost wouldn't amoount to much.

Kwatt,

If you want to install Mandrake without the GUI, just select &quot;expert&quot; during the install process, and select the packages you want to install. You can squeeze it down to about 120MB if need be.

Mandrill,
Klinux runs in a seires of ramdisks, or a virtual drive.
Klinux runs its whole filesystem stucture in virtual memory, or ramdisks.

If you read the screen as it flys by at bootup, you'll see the Kernel is creating 16 ramdisks of 4096K.

Buffering in memory, will use still more memory and cause more problems.
You'll then have memory writing to memory, if you follow what I'm tring to say.

You do have some space left in the ramdisks however, everytime I've tried buff-in/out in memory (no disk I/O), I'll get a error of some sort.
It seems to work best with 64 workunits, saving it's buff-in/out files on the ramdisk.
(you are still using memory, to store these files)

I have it running on two of my machines in the office since Sat night, you can see how there doing at the link below.
Look for the entries that say &quot;Diskless&quot; and &quot;Linux Main&quot;.
http://members.home.net/kilowatt2u/

If I was buffering in/out to memery (no disk I/O), I'm sure it would have crashed by now :Q.

You aren't going to trash the floppy by creating buff-in/out files on the ramdisk.
As a matter-of-fact once Klinux is booted up, you don't even need to leave the floppy in the drive, It's all in memory.
You can move the floppy to another machine and fire it up too!

I hope this helps explain it.

This thread just went to three pages, I;m starting up Crack Rack for Dummies II.

Kilowatt and Mandrill I'll check into that pproxy.

Russ I did not know you could install it that small. I'll give it a try.:) I want everything but I don't want a GUI I would like to learn the command line first.

Thanks All

Kwatt,

If the intent is to learn CL first (rather than saving disk space) you can just leave to the GUI on, and not use it. Just move to a different terminal. You can have up to seven open. The 7th is the GUI, the other six are command line (unless you tell one of them to load the GUI).

The TTY's are accessed by Control/Alt F1 thru F7.

Hey Russ. Is there a trhead out there with some hardware details about your rack? I am interested;). I dunno, I might be settin' me up one of them racks reeeaaaaaaal soon. Thanks, Russ.



SAK, RFDCE

P.S. -- RFDCE should have a site pretty soon.:Q
