Newbie Questions...

Just joined and I have a few questions. I appologize if these have
already been discussed, as I'm still looking through the list archives.

1) Would it be possible to make linux boot disks that boot a machine and
load the necesary stuff into a RAM disk so that the machine would
automatically run the client until a given time and then reboot?
If so, I might be able to comandeer a computer lab full of P200s.

2) Lets say your machine takes 30 minutes to run 2^28 key pairs, however
this is a dialup machine. Lets say you only want to dial up once every
12 hours. Would it be possible to run 24 instances of the linux
client, thereby grabbing off 24 key sequence hunks (or whatever
they're called) and then have it complete all 24 in time for the dialup?
To be on the safe side, you might want to run 23 to make sure that the
context switching didn't eat into your time and throw everything out
of whack. I was thinking of doing this on a smaller scale (like
running 2 or 4 at a time), rather than dialing in every 30 minutes
This would be to get around an idle-timeout disconnect "feature" on
our dialup without having to hog the dialup.

Or is there some way I can get my client to grab a larger number of
keys to try?

3) Is it worth it to put any 386-class machines onto this? I have a few
386s sitting around idle where I work that could crank away at their
little pace 24/7. Or would they somehow tie up the server or not
contribute enough to bother setting up with linux?

4) What's the best way to keep track of your logs on a unix machine?
Since the client doesn't close the file until the client exits,
I presume that you can't mail the output unless you exit the client
occasionally, right?

5) What text can I grep for on the very odd chance that a machine of mine
finds the solution?
