Hi,
has anybody here tried disk capacities (RAID) in the range of Terabytes
in Linux? Will RAID controllers (I mainly use the AMI MegaRaids for
Linux) support single devices of such a size (when using enough 75 GB
drives for example) with the linux drivers? The e2fs limit should IMHO
be at least 2 TB, but I'm a bit unsure if it's possible to access such
a big "drive" through the drivers, so I'd love to hear from someone who's
already done it...
Thanx, Florian

Will CCD camera work under Linux??
Why asking? I have a home security system installed (DIY) that
can alerm and dial out if something goes wrong. I am thinking to
connect the signal to PC running Linux with CCD camera so that
the break-in images can be recorded. A simple idea, right?
Any info/suggestions will be very appreciated. Thanks.

Hmm, could have done that, but to much installed, too much to change
now (and I cannot spare the time). Besides, even if X going bogus, I
should be able to telnet into the machine, right (which I couldn't)?

This I am more would like to know more about. I know netscape was
active when my latest crash occured, but the crash was instantaneously
(no discaccess, screen activity nor keyboard/mouse actions after the
crash. Is the netscape crash that fast on the system (and how does it
do that)?

when you say 99.9% of the system resources, do you mean the cpu time?
This happens several times of the day and I need to kill -9 PID_netscape.

Currently ulimit -a tells me this:
core file size (blocks) 1000000
data seg size (kbytes) unlimited
file size (blocks) unlimited
max memory size (kbytes) unlimited
stack size (kbytes) 8192
cpu time (seconds) unlimited
max user processes 256
pipe size (512 bytes) 8
open files 1024
virtual memory (kbytes) 2105343
The only stuff unlimited is memory related, disk related and cpu time
related. None of these appeard to be a problem. If it had said
unlimited use processes, then I could suspect netscape spawning so
many processes to keep the kernel saturated with work just swapping
between them.

But what about my Adaptec driver? That is located in the same
modules directory and it is found just fine.
How does the kernel "find" the "/lib/modules/2.2.16-3/scsi/aic7xxx.o"
which resides only in that location. (Same as the Advansys module).
Does this have anything to do Lilo?

Umm... that's a very sweeping statement, how about backing it up?
I personally find the use of symlinks to devices very handy indeed; not
least of which because if you find yourself reconfiguring your system a bit
(moving a modem to a different serial port, your CD writer and scanner
change order on the SCSI bus, and so on) the only change you have to make is
redo a symbolic link!
What's wrong with doing that?

I did, and they don't seem to work OK. They have spurious errors, and not
always the same.

I have two double-sided 32M modules. Any of these, when put in bank 0
alone, shows errors (but different ones).

That's interesting, I might try that. I haven't understood some things
about this anyway: When I put my two 4MB sticks in bank 0 and 1, all 8MB
test fine. When I then, additionally, put the (possibly defective) 32MB
sticks in bank 2 and 3, memtest finds errors even in the lower 8MB. The
same happens when I put the 32MB mods in banks 0 and 1 and the 4MB ones in
2 and 3. Is it possible that these thing get remapped in unpredictable
ways?
Thanks for your tips,

Ok I will go easy on you :-)
There is a driver for this thing, but only for Redhat 6.1. I have actually
made it work on my Dell Inspiron 5000 which has the same modem.
Have a look at www.linmodems.org they have some drivers, also notes on

Disclaimer: I didn't make the original statement, but I do agree with
it !:-)
I have found massive problems using /dev/modem when I am using the
modem for more than one application. I have ended up just sticking to
/dev/ttyS? and that sorted out problems like locking and fax queues
going mental when the modem is being used to connect to the net.

I fully support the use of symlinks for things like scanners and
cdroms because they make life easier. Nice, consistent interface to
devices. But for modems, I stick to their /dev/ttyS port :-)

Hi chad...as far as i know.....linux does not support the HP/Travan 14 or 20
GB tape drives. I can say that, because we bought one too, and it won�t work
under SuSE linux 6.4. If there�s a difference by using redhat..i do not know
After the installation we could only wind and rewind the tape...and it
seemed as we could even write on it..but..alas...no reading was possible, so
i don�t know whether it wrote correctly or not ;-)
HP has no linux driver support for this product, and even here in the
news-rooms i still did not find a solution, i guess it�s cheaper to mount
the tape into an Win98 or NT machine and backup thru network

The I/O port number will most likely be the same one that DOS uses. Once

While the Adaptec SCSI adapters are nice, I've found Buslogic works
well under Linux.
I echo the question about IDE hard disks. If you go for SCSI, do that
for your hard disks. Agree with the recommendation of the IBM SCSI
hard disks.
You leave out any tape backup drive. Don't.
I've always used various Matrox Millenium cards under Linux, and
recommend them highly. Currently, the G400 Extra.
256 RAM does seem like overkill, athough the consensus these days
seems to be that 125 is an appropriate target, which not long ago
would have seemed enormous.
Be careful in your choice of case. I've usually picked well known
components of quality and had good luck, but cases have been a pain
for various reasons. Cases from the well-respected major sources can be
expensive and problematic. At this point I suspect I'd just shop at a
show of where I can see the case and get a cheap one that has features
I like.
I'd be interested in whether folks would recommend the Intel
motherboards. There are some advantages for doing so, not the least of
which is their sitting well with Linux.
