Hi,
can anybody tell me, what some entries in /proc/cpuinfo mean,
(e.g.
cpu family : 5 , what is 5 ???
model : 8 , ...),
what bogomips are (on some systems the bogomips = cpu-speed,
sometimes bogomips=2*cpu-speed),
and how the appearance and names of the fields correlate
with the linux-version??
That would be great. Thanks in advance

Hello.
I want to make a driver program which gets information of write size
and offset to disk. The purpose of this driver is filtering between
filesystem driver and device driver.
Where can I get useful information ( document, book, sample program
source code,... ) ?

Is there ready made boot disk with kernel which mount NFS as root
filesystem, (knowing that my newtwork card needs the PCMCIA card
services)

This is very specific, and I doubt there are any books or extensive
documentations. Definitly you shgould go and check the sources for
the existing drivers and how they are interfaced.
Your system should have it under /usr/src/linux.

I haven't seen it myself, its a report we had from an academic site in the
UK we were talking to.
We were concerned because we (used) to use the standard 6.2 supplied kernel
on most of our cluster systems.
The original report came from the states, look at:

Hi,
I'm writing a kernel-module which should
be notified whenever
my
ethernetcard receives a frame (and it should get
the frame
also).
I don't want to hack a call to my module into some
ethernet-card

register my module
as
the receiver for ethernetframes. (And at the same
time to unregister
the

I'm pretty sure (but not postive) that CPU Family: 5 refers to a pentium
class machine here. Sometimes you'll see programs that have compiled
with optimization as i586 instead of i386, so that's my best guess. As
for model, I'd just say it some sort of identification of the CPU
itself, maybe the 8th revision. BogoMIPS are (bogus) million
instructions per second, supposed to be a measure of a computer's
performance. In reality, it has very little to do with a computer's
performance, hence BogoMIPS. It is found by testing how long it takes to
run a small loop on startup, and is usually 2 * Mhz of the CPU, even
according to the kernel source (/usr/src/linux/init/main.c, search down
to bogomips). Hope this helps a bit. -- Matt Lesko

Subject: delete overflow uid/gid files

Hello,
I am running 2.4.0-test2 and for some reason I find a few bogus
files with 65534.65534 ownership. In fact, they are character
and bloch devices in a directory where sure they don't belong.
Permissions are bogus as well. Names are still OK (used to be C header files).
Issue is: I cannot delete them. Even as root or as test user 65534.65534
I get permission denied on most operations such as rm chown chmod ...
Any hints welcome (disk editor?).

Since mouse movement is assumed to be somewhat random, it is used to
generate 'randomness' for /dev/random etc.

You won't say that after you see Perl's CPAN collection. Granted, it's
mostly non-GUI stuff, but hey, most programs _are_ non-GUI, and even GUI
programs are mostly made of non-GUI pieces.
CPAN is the main reason I use Perl and not, say, Python. Ugly the
syntax may be, but being able to say "cpan" and then "install LWP" and
suddenly having a full-fledged Internet I/O library installed is
unbeatable.

The first thing to do is fix the buggy program that's leaving CLOSE_WAIT
states on your server. Then once you've done as much as possible in
that regard, see the setsockopt() function: in the server, set the
SO_REUSEADDR option to force bind() to work even if there are
wait-stated sockets on that port.
Beware, SO_REUSEADDR can let you do nasty things like bind to port 80
while Apache is running. It's not a cure-all, just a way around the
"wait for the wait state to expire" solution.

It depends on what you want to do with that frame. If you just want to
display it or save it to disk, you can do that in user mode with
libpcap.
If you need to modify it or something before the network stack gets to
it, there's a mechanism that routes packets down through user mode and
then back up into the kernel. Packet socket? Something like that.
Anyway, you write the filter as a user-mode program, and it asks the
kernel to send data through it.
If you really have to do this in the kernel, look at the firewalling
mechanism. I'll bet you can hook into it to do some custom things. In
fact, I'm sure of it: just write a masquerading module, like
ip_masq_ftp: it hooks into the masquerading chain to diddle the data in
FTP packets.
Good luck,

Well, here is one:
# include <netdb.h>
# include <stdio.h>
int
main (void)
{
struct hostent *entry;
char hostname[] = "www.yahoo.com";
if ((entry = gethostbyname (hostname)) == NULL)
fprintf (stderr, "lookup of %s failed\n", hostname);
return 0;
}
If you compile ("gcc this_file_name.c -o the_executable_name") this file,
then run "strace the_executable_name > output_file 2>&1", the output file
may give some hints about what the name resolver is trying to do.

Sun claims that their Java does not work on linux in SMP (

Can anyone point me to a good Java implementation that:
1) Has a fairly good debugger.
2) Can run on SMP systems.

Why don't you look at the /etc/resolv.conf file in your HD? There you'll
find both your domain name and the server ip. Copy this file to your DoC
system.

My linux's C library (libc-2.1.1.so) do supplies the entries needed for name
resolution, so I guess that, under Linux, there is no need for further
libraries than the C one to get the name resolution functionality.

BIND stands for Berkeley Internet Name Domain and is a collection of
programs (notably, the DNS name server), tools (like nslookup) and client
libraries used to define, resolve and maintain name-and-address pairs under
TCP/IP environment. In short, it is the code by which you also get an IP
address through a DNS server.
BIND supplies the client portion in form of a library (libbind.a) whose
functionality is replicated in the libc itself in Linux (at least in my
system...).
If you have further questions about this matter, better move to
comp.os.linux.networking (I'm posting this also there), since this is not
the right ng for this matter.
