You tried to access an IDE disk 3 times simultaneously. IDE is a
piss-poor technology for multiple access on the same bus or disk.

You must do math a little differently than I do. Where does that 990
seconds come from? My calculations yield 495 seconds (assuming that
those are supposed to be 160,166,169), for a throughput of about
12MB/sec.
Why don't you check out some disk benchmarking software like bonnie, or
better yet, tiobench. tiobench.sourceforge.net

I just want to emphasize -
If you use coax and the cable is cut anywhere, the whole network goes
down. (yes, both sides of the cut lose connection even to other machines
on the same side!!)
I would use cat5 and put the cable in first. Hubs (after one to
support your use) can go in later and can be upgraded as needed. Tenants
wanting a connection can be charged enough to pay for the upgraded hub.

Hi all,
I'm looking for a good tape drive. I see a few different brands that claim
to support Linux, i.e., Exabyte, Onstream, HP, etc.. I would like to hear

I loaded Redhat6.2 on HP Pavilion 9694. It has an HP EN1207D-TX
PCI 10/100 fast ethernet adapter. Everything worked except it
didn't recognize the ethernet card. I ran "linuxconf" and pointed
to the three different Hp drivers that came w/ RH6.2, but none of
these worked. I get the following line in "/var/log/message":
...... network: Bringing up interface eth0 failed
is there a driver available for this ethernet card?

install with the hd on the non-raid controller, boot into linux,
rebuild the kernel with the hpt370 patch, configure the system for
booting off the raid i.e., edit /etc/fstab. then power down, plug the
hd into the hpt370 and reboot. worked for me. helps to have a rescue

It's probably worth making sure first that the machine is being shut
down cleanly - killing the power with files open *might* lead to this
type of error.
More likely it might be due to something in the boot scripts - check
/etc/rc.d/rc.sysinit (if it's redhat or similar) for anything that mounts
the root directory earlier than it should.
Finally, are you passing something at the lilo boot prompt or in
/etc/lilo.conf that could cause / to be mounted already? What do the boot
messages have to say about it all?
Hope this helps.

The operative keyword is 'dat', and they come in various sizes and
prices. New of course, they are very pricey, but I bought one a year
ago on ebay for less than 200 USD, a DDS2 version which can store up to
8 gigs on a tape you can also get brand new for less than 5 USD a copy
on ebay. DDS3's can do up to 24 gigs a tape IIRC.
Its faster than QIC or Travans in that the drives have almost random
access to anyplace on the tape in a fairly short period of time, unlike
the QIC's and Travans that have to sequentially search the whole tape to
find one file, often in real time speeds, not fast forward. Thats a 1-2
minutes vs an hour or more difference. I have seen 90 megs a minute for
short periods of writing on my system, but the average for a whole
backup is probably more like 30 megs/minute over a full 3 tape, 17 gig
backup here.
One disadvantage is that when it thinks its time to clean its head, you
have no choice but to feed it a cleaning tape, which it will run for a
few seconds and autoeject, so you need to buy those too when buying a
tape supply.

this is nonsense, since Linux schedules IDE activity.
IDE is a superlatively cost-effective "technology".

Depending on the building, etc. have you considered wireless 802.11 instead of
cabling the building? You would have more flexibility, and wouldn't need to
run wires, though it would mean the tenents would have to buy an appropriate
wireless card, which is more expensive up front for them, and you would have to
worry about security....
Do they still make 10base2 cards in any great quanity? It is definately a
dying technology. I certainly remember the old game of 'find the break' in the
10base2 cable, and am glad I no longer have to do it (for those who have never
had the pleasure, 10base2 was connected as a ring, and if there was a break in
the ring, it brought down the whole network, just like the old fashioned
Christmas tree lights)..... I agree with the others that you want to have one
switch with connections to a hub per apartment, or even just one jack, and let
the tennants run the wires....
Another thing you need to think about is security -- you don't want the guy in
apartment #6 spying on the people in apartment #4 because they don't know
enough to put passwords on file sharing, etc. Another thought -- are you going
to be masquarading the apartments to a single IP address, if so you probably
want to give each apartment a separate IP range with dhcp.

Need more info. Motherboard type (brand and model) Hard drives installed (brand
model
and capacity) On hard drives where are jumpers installed? Are you sure the cables are
plugged in right? OOPS forgot CDROM drive brand model speed. Where is the jumper on
the
cdrom drive?
Find someone else in the future to do your hardware stuff it seems like the person
you had do it does NOT know what they are doing or your system would be just fine.
