Hello,
On Linux how do we implement a new protocol which is required to work in
parallel to other protocols eg TCP/IP etc.This protocol is to be
implemented just above the ethernet MAC layer.
Thanks in advance,

You'll find all you need at one of the portals dedicated to embedded Linux:
http://www.linuxembedded.org/
or
http://www.embedlinux.net/
There are probably more portals than these, though.

Hi,
I'm looking for some toolkit or working enviroment for
device drivers development under Linux.
I mean compiler, debugger and tools related to drivers stuff.
Can anybody recomend such toolkit , free or comercial ?
Thank you.

Regarding Video cards, I would neither buy a new ATI card as their
driver support for linux leaks, nor any clone of a well known card.
You should have a look at the websites of big distributors like RedHat
oder SuSE, who both have compatibility databases online.

The reason is that the VFAT filesystem does not have inodes at all.
The inumbers are only allocated by the Linux VFAT driver (actually
by the underlying FAT driver) when they are first needed by the VFS
(yes, VFS needs the inumbers).
Since the inumbers are never stored on disc, chances are high that
they will get allocated in another order after a re-mount, as you
have observed.
Changing this behaviour would be a non-trivial task, to put it mildly.

I'm afraid you'll have to live with that :-(

If you can't find a maintainer of a part of the kernel, you're generally
in the the right place here.

Device drivers are generally built as part of the kernel (module), so
gcc and friends are the right toolkit for the task.

Funny, others explicitly recommend ATI cards (bought one last month, works
like a dream), and http://www.xfree86.org/ certainly leaves the impression
that the ATI drivers are being maintained and improved...

Hello,
We are thinking about using a Diamond Systems Corporation
MM-16 board for an application.
We have searched the internet and the Diamond Systems site,
but could not find much information, only a user-space application
accessing the board and Dos/Windows drivers.
Does anybody know if a Linux device-driver exist for this board?
Anybody have any comments on using this board with Linux?
Thanks in advance,

We have recently switched ISPs for our hosting needs. On April 1st, our
online store (www.chiltown.com) will be live and based upon our advertising
budget, we expect 100,000 page views per day for the first week.
I would like to know how others actually test load and if someone could help
us either prove or disprove that our site (www.chiltown.com) can handle the
load. We are interested in testing only the performance / load on the first
page.
We would also like to know how others test their sites for load as well as
the best ISPs that can take some serious pounding. Any information you can
send to me is greatly appreciated. Thank you in advance.

First of all... Don't cross-post, there's no possible reason for you to do so.
Now that we've gotten that out of the way... Apache will handle that load
without any problems. I would look into the hardware that will be used on the
server. If you own the box, make sure you're using SCSI hard drives and have
ample RAM as to prevent your system from swapping.
The only test for a website is time, there's no magic potion, it's either fast
or it isn't. You may have the coolest ping times with a certain provider but
that doesn't ensure that your pages will get served out as quickly as you want
or need them to be. Stick with Tier 1 providers, millions of people can't go
wrong. :)
Hope this helps,
Andy

Mercury just announced a web-pounding service. You just send them
you're URL and they'll put as many hits per hour as you pay for. It's
free if you sign up before the 31st of March.
http://testyourlimits.merc-int.com/cgi-bin/portal/ActiveTest/trial.jsp
Or, if you're the DIY type, purchase Webload, Silkperformer or any of
the other big tools and 300 or so virtual users, then negotiate with
any ISP with a true connection to the Internet (you'll need more the
16MB), then rack-mount a couple of NT boxes (you should only need 3 or
4, each with 178MB RAM) to act as agents. With the load tool, record a
script that hits your front page, compile it, and launch it from your
agents. Be sure to set the 'IP spoofing' feature on the tool to
simulate many surfers hitting your site.
I figured that I could generate 500,000 hits per hour with just 150 or
so virtual users on two NT boxes rack mounted at an ISP that charges
for throughput (gigs at a time).
Send me an email if you need more info.

Hi,
I setted up the SQUID proxy and everything works but one thing:
I have 12 boxes connected to the server and an old 3COM ISDN router.
Now I setted up the refreshing options for the cached pages so that
SQUID looks for newer version of the cached pages only if the request
comes in a time that's in a particular ratio with the expiring page
time.
Now what happens is that in the wonderful MS IE (BG SUCKS) is not
possible to have 0 MB of cache like in the NETSCAPE, but there's a
minimum of 1% of the total disk space to employ as Internet cache; so
sometimes I see the router that's working also if noone is connected.
I' m running behind a firewall and in the logs I can see that the
connection are addressed to some sites I just watched. So I suppose that
the problem is in the comunication between the cache I don't want (IE
5.0) and the cache I want (SQUID).
In the easy squid.conf file (about 50 pages of encrypted config options)
I saw that there's something like ICP that looks like the parameter I
have to touch to control the cache communication.
Does anyone know what I am talking about???
(I don' t)
THANX FOR ANY SUGGESTION

Hi
its not so much if the server can handle the load it is weather or not the
links to the net can handle the load but that would work out at around 1
hit a second and yeah any half godd machine would be able to handle that
but it would depend on how you would set that up or if the hit are going
to come in lots at once like say lunchtime

But how does one usually do 'loose' communication between kernel modules

That's quite a serious project for an undergrad OS class... ext2 will be
complex, but that's because it has been well optimised for typical UNIX
applications. I'm afraid UTSL ("Use the source, Luke") was not invented
for nothing: it is usually the best way to understand how somethine
really works.
I recommend you read the Bach book; also consider emailing Andy
Tannenbaum for references on Minix: he's a teacher, so I'm sure he won't
be above replying. You could try Ted Ts'o's page at MIT -- he's written
a number of papers on ext2.
