I am using a RedHat 5.2 server to masquerade an 80+ user office to
provide Internet access. A major sticking point with my boss is that
the machine must be able to log Internet usage among employees.
I have tackled this problem from a number of angles and I finally
decided that I would write a shell script to handle the job (I mainly
chose this because I wanted to learn shell programming). The script is
a follows (it is run out of my home directory <bferris> right now so
files are based there)...
#!/bin/sh
# This script monitors Internet usage by monitoring the
/proc/net/ip_masquerade file. This file
# stores info in the following format...
# type (TCP,UDP,etc.) source_ip:port dest_ip:port masq_port
# Ip addresses are in hex format. Linux uses this file to keep track of
which ports it masqued
#addresses to.
tcp_only="TCP"
# I use a temporary file <addition> to store the results of the script.
The first thing added to this
# file is the date.
echo $(date) > /home/bferris/addition
#I use a read to pull the type, source_ip, and dest_ip from
/proc/net/ip_masquerade
while read type source dest rest; do
# I check to see if the type is TCP since I only want this type
if [ $type = $tcp_only ]; then
# I wrote a quick and dirty cpp prog to convert the hex
IP address into the regular x.x.x.x format
source=$(/usr/local/bin/hextodec $source)
dest=$(/usr/local/bin/hextodec $dest)
# To avoid having to make a nslookup call for every IP,
I created a list of addresses and
# their host names in the host_list file. If the
address hasn't been added to the list yet...
if dest_name=$(grep $dest /home/bferris/host_list) ;
then
adder="$source $dest_name"
else
# ... I make a nslookup to find the server name.
dest_name=$(nslookup $dest | grep Na | cut -c
7-)
# If the lookup doesn't come up with anything,
the name becomes unknown
if [ -z $dest_name ]; then
dest_name="Unknown"
fi
adder="$source $dest $dest_name"
# Since this server wasn't in the host_list
file, I add it
echo $dest $dest_name >> host_list
fi
# I check to see if I have added the $adder to the

First, let me say that all I know about shell scripting came from
this project. This script works but I have a feeling that there might
be a better, more efficient way of getting the same results. This
script would currently have to be run by cron every once in a while to
properly log. With that in mind, I will now ask all my questions
-Is this script the answer or am I barking up the wrong tree?
-Should I do something with CPP that would run 100x faster?
-Should I just bite the bullet and install a proxy like squid which
does logging too?
-Should I do something crazy like install my own local DNS server
and do logging here (I want to set up a DNS for fun anway...)?
I know that is a lot of questions so any thoughts the world has on
the subject is much appreciated. Besides, the whole thing can
definitely be chocked up as a learning experience if nothing comes of
it.

Hi !!
I've installed RedHat 5.1 on my PC (Pentium II 300 Mhz). The
kernel is v2.0.34-6.
I got the kernel v2.2.1
I have several questions :
- Can i use RH5.1 with new kernel 2.2.1 ?
- I make the new kernel and put it on a floppy disk.
During the boot, i have a kernel panic message... :
Request_module[block-major-3] : Root fs not mounted
VFS :Cannot open root device 03:05
Kernel panic : VFS : Unable to mount root fs on 03:05
Can't understand ?
- Where can i find modules utilities for kernel 2.2.1 ?
Tanks for your Help...

Subject: Segmentation fault
Date: Wed, 3 Mar 1999 08:55:39 -0600
Can someone tell me precisely under what conditions a segmentation fault can
occur under Linux?
I'm trying to find a particularly tricky bug in a C program and haven't been
able to track it down. I compile the exact same source using M.S. Visual
C++ 6.0 under Windows NT and gcc (ver 2.7) under Linux (Slackware
distribution, kernel version 2.0.27). The program runs fine under NT, but
crashes with a segmentation fault under Linux. Furthermore, it crashes at
different times in the program and can sometimes take the XTerm in which it
is running down with it.
The program is completely text (console) based and doesn't use any unusual
libraries.
It is fairly complex and includes a lot of allocation/copying/freeing of
memory and complex array sorting.
Thanks in advance,
jeff --

Youngser,
My BIOS has a PNP / PCI feature that allows me to
enable a pnp OS, or disable it. Also, individual
irqs may be pnp-enabled. The default is to disable
the pnp os, which is how I left it. Since I know
that I have an Intel PCI motherboard, this
appeared to be the safest choice. And I haven't
heard about linux becoming a plug and play system.
Does your BIOS have this option? And if it
doesn't, are you also running windows '95 (or
'98)?

I would expect the latter construct would be rather safer in general.
Bash, and most GNU utilities (and by this, I mean GNU, not "purely
Linux stuff") have been written so as to eschew arbitrary limitations
on argument sizes.
This doesn't make it sensible to instantiate a loop that holds onto
thousands of arguments all at once. Certainly more sensible to
serialize their evaluation, particularly when you consider that the
"operate" takes place serially.

You may want to use "ls -f" to list the set of files, as that will
skip the step of sorting them. It may also avoid the need to look at
more than minimal "bits" of the i-nodes, which can improve
performance...

Your question is still badly phrased. The one you want to be
asking is "Is it possible to create a cross-compilation
environment for FreeBSD on a Linux box". The answer is a "very
likely". How difficult? Dunno; I've never tried gcc's cross-
compilation capacities. I wouldn't be surprised if it were pretty
easy, though.
But, assuming you've built a kernel and booted, you're still stuck
-- it'll try to run /sbin/init....and even if Linux keeps it
there, chances are that program will just fall over and die. And
if you fixed that, you'd find zillions of other things that won't
work unless rebuilt for FreeBSD. Some of that rebuilding will be
simple cross-compiling; others will require actual code rewrites.
In short, it's not a reasonable thing to do to try to graft Linux
userland onto a FreeBSD kernel. It's likely *possible*. But not
reasonable.
: Can FreeBSD work with ext2 file systems ?
A guy I just hired tried to answer that question a few days ago,
with his dual boot Linux/FreeBSD system. The answer appears to be
"no".

You don't even need that anymore. International treaties have made the
U.S. switch to `standard' copyright law, too; up to ~1970, you needed
to have a "Copyright"/"Printed in" notice in your book to have it
copyrighted, but these times are over.

I would rather have them working apart. It seems to me that the best
bet for Open Source is to have several different systems being worked
on independently, with cross-pollination of really good ideas that
make sense on the other systems.
Having more than one way to look at things means that people who use and
work on different systems will have more ways to get ideas. I think any
organisation which can reasonably run more than one Open Source OS
*should* run more than one. (Here at Rowan we seem to be converging on
Red Hat and FreeBSD as our pair of free OSs. Within a week, people
using both systems were saying "Gee, that's a good idea, we should steal
it for these other machines . . ." The heavy lifting is done by SGI
workstations, which come with amazing graphical software, and even at a
few years old they are still a first choice. But one doesn't really
need the power of an O2 just to edit homework files, so we've added
a second tier of workstations made out of P90s and other leftovers.
Can't beat the price.)
There are other advantages, too. Suppose Bill Gates buys Red Hat and
shuts them down. Now what? Well, we've already got another system
running on a half-dozen machines. Switching from one Linux to another
may not be a big deal, but there's still going to be overhead. With two
systems, during the time we were switching over, we would still have a
bunch of machines that worked and weren't dependent on Red Hat
distributions at all.
That leads to another advantage of many Open Source OSs: if somebody
with deep pockets wants to attack Open Source, he can't just go after
a single target. There was some discussion about what happens if Red
Hat decides to make an OS monopoly (a silly idea, what with the GPL,
but still something people may worry about). If the people at Red Hat
found out that half their users were using another system too, well,
that may help keep them from getting any silly ideas.
The "Linux vs FreeBSD" and "Best Free Unix" threads are just a waste of
bandwidth; compare "what's the best food?". I think nobody should
criticise an open source OS unless they personally use it and like it,
but see ways it could be better%. And then they should say something
useful, like "Hey, I noticed that SystemA has the following spiffy
feature; how hard would it be to adopt something like that for SystemB?"
(Or, better, "I have here an implementation of a spiffy feature from
SystemA for SystemB. You can download it off my web page at ...")
--
% For an OS you paid money for, you have the right to object in any
way you want.
--
A little friendly rivalry is okay, but if somebody comes to a newsgroup
and sees "Linux sucks!" "No, BSD sucks!", that person will likely just
be scared back to Windows and be sorry he ventured out.

You should insert the following in your /etc/conf.modules file:
alias parport_lowlevel parport_pc
options parport_pc io=0x378 irq=7
where io, irq should be the address and the irq of your paralel
port.
Restart the lpd daemon and you shoul be set.
