Subject: Redhat 5.2 & Linksys EtherPCI LanCard II Problems PLEASE HELP!!
Date: Tue, 23 Feb 1999 00:30:41 GMT
Hi Folks,
Here's my setup:
- Linux Redhat 5.2 with 2.0.36 kernel.
- Generic NE2000 Ethernet card (detected by Linux, connected to
Internet and working fine)
- Linksys Combo EtherPCI LanCard II (not detected, not working)
OK, I've been trying to configure a second net card on my Linux machine
so that I can setup IP Masquerading. I have read and re-read all of the
relevent FAQs & HOW-TOs in regards to Ethernet & IP Masquerading setup.
The first net card (Generic NE2000 which is connected to my cable modem)
is working perfectly in Linux. It is detected on boot as eth0 and
assigned an IRQ and Base Address just fine.
The second card is a different story. It is a Linksys Combo EtherPCI
Lan Card II. According to the HOW-TOs I have read and the Linksys
website, this card should work with the generic ne2000 driver (ne.o). I
have tried every different combination of things I can think of to get
this bugger working to no avail. I have the following in my
/etc/conf.modules:
alias eth0 tulip
alias eth1 ne
I even tried this:
alias eth0 tulip
alias eth1 ne
options ne io=0x6800 irq=12
...this didn't work either.
I have also tried adding an append line in my lilo.conf:
append="ether=12,0x6800,eth1"
(I also made sure I typed "lilo" at the prompt and rebooted after doing
this)
...no dice, again.
Now, when I reboot, eth0 shows up in the boot log just fine as always.
However, no matter what I do, eth1 will not show up. If I do this:
modprobe eth1 dmesg | tail
I get:
ne.c:v1.10 9/23/94 Donald becker ([EMAIL PROTECTED])
NE*000 ethercard probe at 0x6800:00 20 78 10 13 4b
eth1: NE2000 found at 0x6800, using IRQ 12
So apparently it is able to detect the net card. Why won't it detect it
at boot and why won't the netcard work, though?
If anybody has any ideas on this or experience with this card, please
let me know. I'm desperately in need of getting IP Masquerading going
as soon as possible. Please feel free to email any replies directly to
[EMAIL PROTECTED]
Thanks a lot,
Daniel Koerner

OK, fair enough. I was confused by the following:

I thought that the sentence "Even though the user data is fine, by corrupting
the ECC the drive *has* to determine that the sector is unreadable" meant
that you were saying that errors in the ECC bits were uncorrectable.
(I still parse it that way.)
Your point about errors propagating to multiple blocks is valid,
although your conclusion that this invalidates same track parity groups
(aka single-disk RAID) {I keep trying to change the term, but
"Single disk RAID" is just a lot sexier than "same track parity groups"}
is invalid; as I explained earlier, interleaving of parity groups
can protect against such errors, so long as the interleave factor is
greater than the number of physically contiguous blocks that will
have problems.
Your (Malcolm's) and Ralf-Peter Rohbeck's point that many blocks
can be reread on re-try is valid: it is pointless to try to use
single disk RAID to protect against such errors, that you can simply
recover from by waiting for a rotation, and then re-reading.
Again, single-disk RAID would only be useful if there is a class
of errors that (a) are not readable on retry, or correctable by block ECC,
and (b) that do not extend for more than a certain, probably small,
number of physically contiguous blocks. (Note that errors that spread across
multiple adjacent tracks is probably okay for single disk RAID,
so long as on any given track the error does not spread across more
than physically adjacent blocks than the parity group interleave factor.
{True for strictly same-track parity groups; less true if parity groups might
accidentally spread across the end of a track, because the physical layout
is hidden.})
Ralf-Peter presented some useful data about error modes.
I wonder if I can entice him to discuss how long the "deafening"
(thermal asperity) lasts - either in time (us), or in terms of physical disk blocks
that might be rendered unreadable.
Similarly, how long does the head bouncing last?
Defects caused by head oscillations and bouncing/crashing might have some
interesting tradeoffs. If the duration of such episodes is longer than a desirable
parity group interleave factor, but the distance between bounces is also long,
we may want to make the parity group interleave factor SHORTER than the
distance between bounces, although larger than the extent of damage at each bounce
site. I'm guessing the head physics is such that it has a characteristic frequency
(oof - variable speed disks for portables might mess up this sort of analysis
- but I'll forget about them for now).
---
Anyway, we are talking single disk RAID for magnetic media to death. How about
single disk RAID for CD-R and CD-RW --- probably the most popular archival
storage format around nowadays? Head crashes should not be an issue here.
What are the error modes for CDs?

Hi Jeff,
I get the EXACT same behavior on my Dell Inspiron 3000! Right after I
install the supplemental disk it crashes and forces me to cold boot.
Did you find a solution? I am trying to install linux on my external
Jaz through my PCCARD Adaptec SCSI controller...don't know if it is even
possible...

Hi,
I am looking or an inexpensive new laser printer (~300) that will work
with linux.
Most of the hardware compatibility lists seem to contain slightly older
items.
I'm a bit discouraged because the 'top rated' printers s are often
windows only,
and the mfr's don't seem to putcompatibility or emulation data on their
websites.
What would be a nice new printer to buy?
If posting a response, please e-mail too if possible.
Thanks,

For what it is worth, I got it to work under the "diamond stealth 2000" or
with anything with a S3 Virge chipset, but I am finding it acts funny
under certian situations :(
did you get it to work iwth the new version of Xfree86? That is where I

Subject: Anyone out there with a RedHat installation success story?
Date: Mon, 22 Feb 1999 01:07:53 GMT
I'm planning to build a low cost (under $600) RedHat system and need advise
as to all components (the entire enchilade - as we say here in Texas).
I am hopping to hear from someone who has simply followed the RH
installation instructions and finally shutdown with a smile. Is there
anyone out there with this experience or is this system as cantankerous as
most sites seem to indicate. I'm hopping to setup as many as 1000 machines
per year and that why I'm looking for simplicity. I have an opportunity to
disrupt the Microsoft tax system on a corporate level but I need help to do
it.
If you can help please document every component in detail. This system
requires the following options: sound card, CD ROM and 56k modem.
Additionally I must incorporate a touch screen which I think few of you have
experience with.
Thanks all
James
Thank you
