A couple of comments:
1. It can be done:
vsink0: dmesg | grep -i 3com
eth0: 3Com 3c905B Cyclone 100baseTx at 0x2400, 00:50:04:d0:72:b8, IRQ 11
eth1: 3Com 3c905B Cyclone 100baseTx at 0x2080, 00:50:04:d0:71:78, IRQ 11
eth2: 3Com 3c905B Cyclone 100baseTx at 0x2480, 00:10:5a:ac:2d:02, IRQ 11
eth3: 3Com 3c905C Tornado at 0x2800, 00:01:02:45:c3:9d, IRQ 9
eth4: 3Com 3c905C Tornado at 0x2880, 00:01:02:45:c3:96, IRQ 11
This is on a machine running RH 6.2. The NIC's were added after installation
and configured by hand.
2. You didn't post the details of how you had configured the cards. It is
a fairly common mistake to give them IP addresses on the same network, like
192.168.10.16 and 192.168.10.17. This can cause symptoms similar to the
ones you report.

?! The device names and numbers for (almost) every device that the
Linux kernel supports are in /usr/src/linux/Documentation/devices.txt ,
and there is often a logical progression. /dev/hda1 is major 3, minor 1
while /dev/hda15 is major 3, minor 15 and /dev/hda22 is major 3, minor
22. Make sense?

check you xconfig, in RH 7.1 the PPP may not be supported by default.

No, I didn't say that it was the bottleneck. To pretend that anything
that is not a "bottleneck" can be dropped from the equation isn't correct.
And trying to equate sheer capacity with web-serving capacity isn't
correct. Even though the database machine may not be anywhere near
capacity, it is still part of the equation.

As just a quick, fast, "off-the top of my head" example, using a
count() function when you're trying to benchmark a join isn't exactly
optimal - how much did efficiedcy differences in the count() code affect
the results? In order to find that out, you then have to benchmark the
count() routines, and do the math.

That may very well be true - but both systems were designed to run
under different configurations. I would not pretend to think that a
configuration that suited Postgres would suit MySQL/InnoDB, nor would I
expect the default configuration of either to be anywhere near optimal.
Furthermore, you didn't mention anything about whether fsync() was enabled
or disabled on either, which can make *huge* differences.

Actually, I think that is a wonderful idea - and I'm going to apologize
for being so rude in my previous message. I believe that what I said was
correct, but I could have been a lot more nice about it.

Well, that's not entirely true. They did not disclose the two
"closed-source" databases because of legal issues - after speaking with
the person that did the tests, I can tell you that the two companies who
make the products have histories of lawsuits over benchmarks.
In the case of MySQL, you're right - they *initially* didn't let them
configure it. However, they realized their errors, and changed that. I'm
not going to pretend it was perfect, though. : )

I've actually been giving a lot of thought lately to a good database
benchmarking methodology, and have a few ideas, but I'm far from perfect.
The best, for *me*, is to keep a log of queries executed on *my* servers,
and use those for benchmarking, but that won't mean much for systems that
differ greatly from what I'm doing. Want to work together, and see what
we can come up with?

Hello;
I am putting a RedHat 7.1 server together and am using an ATI
Xpert 2000 for the video card. I am able to go through the X-windows
based install, but when trying to boot (post-install) to X-windows
the screen just flashes several times and never successfully starts
X-windows.
Running the Xconfigurator manually, the correct settings are
displayed for the monitor and video card but the test of the
X-windows environment fails with "There is a problem with
your X configuration".
I have also tried the setrage command to try to get this working.
Has anybody resolved a problem like this?
Thanks,
Ross

You shouldn't have to change a thing. The card should use the highest
possible speed w/out any intervention on your part.

Hi Mario,
I had a fight with the same card last week. This is how I got it to
work:
1 Get the Realtek RTL8139 driver source from www.scyld.com
2 Compile using the command:
kgcc -DCARDBUS -DMODULE -Wall -Wstrict-prototypes -O6 -c rtl8139.c -o
realtek_cb.o -I/usr/src/linux-2.2.19/pcmcia-cs-3.1.24/include
-I/usr/src/linux/include
(all on one line of course)
3 Put the resulting realtek_cb.o in /lib/modules/2.2.19-7.0.1/net
4 Edit the file /etc/pcmcia/config and add the following lines in the
device section:
device "realtek_cb"
class "network" module "cb_enabler", "realtek_cb"
5 and the following lines in the Ethernet adapter section:
card "Dynalink L100CLV CardBus 10/100 Ethernet Adapter"
manfid 0x0000, 0x021b
bind "realtek_cb"
6 Then restart pcmcia services with:
/etc/rc.d/init.d/pcmcia restart
I'm not sure if I had to do a depmod before step 6. You will see if it's
needed.
This made it work for me, using RH7.0 and kernel 2.2.19. Of course, you
will have to modify the version numbers in all coomands according to
your version.
Good luck,
Albert

lm_sensors works just great on a KT7. Get the tarball from
http://netroedge.com/~lm78/ , compile it, run sensors_detect and do what
it tells you to. After that, just enter "sensors" at the command line
and you will get a reasonable amount of info. There are GUI frontends,
too, but I don't bother. HTH,

I just wanna say that I think you're nuts if you think that a dual VIA

Performance tests have shown that a dual VIA gives same or less
performance than a single VIA at the same clock rate. The dual VIA
chipset is just dumb. VIA chipsets are dumb. They suck; they're

Hi,
I have a machine that has onboard serial support for two ports, and an
additional serial card (Siig CyberSerial 1-port) that supports 1 port.
I'd like these three ports to show up as ttyS0, ttyS1, and ttyS2 at
boot, the the kernel always seems to want to assign them ttyS0, ttyS1,
ttyS4. Does anyone know how to achieve this? I've tried setserial, but
it complains that the port is already in use when I set ttyS2 to the irq
and address listed for ttyS4. Its interesting that the kernel complains
about a "Redundant entry in serial pci_table ...".
