Date: Fri, 1 Dec 2000 12:05:52 +0800
Dear All
I am trying to develop an application by using a USB IrDA. I have found some
information about USB development under Linux. Unluckily, I cannot find the
information of IrDA on Linux.
Would you give me some ideas, advices or resources to help me to solve my
problem?

[snip stack dump]
"about once a day"? Does this problem occur at the same time every day,
or does that vary? If it's the same time every day, then a cron job is
doing something bad--find which job that is and debug that job. If it's
varying, the problem will be a bit more difficult to diagnose.
If the problem is always giving out "swap_free" messages, that narrows
it down a bit. Two things that could cause this are a bad partition
table and a hardware problem. Might want to check the swap partition
itself for bad blocks (using "badblocks" of course) and use cfdisk or
fdisk to look at the partition table and make sure you don't have
overlapping cylinders or something.

Is there a version of top that will give me a read out of which
processes are active on which processor? this is an 8-way system so it
would be intriguing to find out..

Subject: Freezing Box
Date: Fri, 01 Dec 2000 05:16:23 GMT
I work for Ossec International (ossec.com, if you're interested in our
page/product/whatever). We have recently installed a firewall at a
company in our base here in Sydney. Everything was going okay until
three weeks in, when it suddenly stops, it just freezes - no keyboard
input, nothing.
We thought at first it might be a hardware problem/conflict of some
kind so we took out the four-port ethernet card and replaced it with
three standard ones. Then it was still freezing, so we just replaced
the entire box with one with a quicker processor.
It's still freezing.
The only clues we have to what may or may not be happening is one entry
in the Apache access_log which gives a line that looks like this:
^@^@^@^@^@^@^@^@^@^@^@
right after the freeze is registered as happening.
The company in question gets alot of emails every day; over 5,000. Even
though they use Microsoft Exchange as their mail server ( we shan't
hold that against them too much; we're a pretty easy-going company, as
companies go ) it still shouldn't be enough to freeze the box up
entirely.
We are using a slimmed-down SuSE 6.4 on the box ( slimmed down in that
it's a firewall; we don't have a compiler, or any other uneccessary
stuff on there that might interfere with security in any way ).
Please help! I am but a humble trainee with no clue as to why this is
happening. Any more freezes ( it's now once a day, at half three in the
afternoon, bang on time - sometimes more ), and they are probably going
to cancel the contract, and as we are such a new company, we need all
the contracts we can get!

Prerequisite for further information: Knowing what shell you're using.
Devoid of other information, I'd suspect that you're using Bash. You
can verify that by typing:
% echo $SHELL
I get "/usr/bin/zsh"; you will fairly likely see "/bin/sh" or
"/bin/bash".
There will be peculiarities for different shells; a good place to
start is to try things like:
alias ll='ls -l'
which tends to work with any shell that is descended from the Bourne shell.
See also the documentation for your favorite shell.
% man bash
% man zsh
% man ksh
% man tcsh
may all be useful things to try...

Who says it is supposed to happen ? Red-shitforbrains-hat ?
Looks like that #$%*# init that Redhat uses, guess they never
counted on multi-user logins on the console.
Well I say "FOAD" to Redhat. Does SuSE do the same thing ? I'm
pretty sure Slackware doesn't.

Darren, this response is usually due to a syntax error in your script.
This can be as simple as misspelt syntax, or may be caused by using an
imported script from a windoze box. (Ie: the script has added ^M
characters at the end of the lines)
Most firwall scripts are fairly long, with several references to the
ipchains command. If the error is caused by syntax errors, simply place
a few "breakpoints" in strategic places and you can then isolate where
in the script the errors are occuring.

Don't use Redhat 7: stick with 6.2. Version 7.0 may well be the worst Redhat release
ever! It's got quite a lot of bugs, ships with an unstable compiler unable to
build the LInux kernel, and so on.
