I am running redhat 6.1. I have installed a new kernel (2.2.14).
My qestion is: where does the file /boot/module-info come from?
It seems to be out of date now.
Thanks

I'll bet you named it "test". There's a utility in /usr/bin called
"test". Try "./test".

To control the /modem/ directly, you'll need to open the modem device
(convention dictates that there should be a symlink called '/dev/modem'
pointing to the real serial device). Take a look for a terminal emulator
such as minicom to find out how.

Under Red Hat, the standard way to bring up the first PPP connection would
be to use 'ifup ppp0' or assume that there's a permanent connection and
leave the user to setup dial-on-demand if there isn't. Why does your app need
to bring the PPP connection up by itself?

*NIX uses a very different approach to Windows; a) you should call external

Subject: Re: system requirements?
Date: Thu, 2 Mar 2000 10:21:21 -0800
Just thought I'd jump in here. A couple of points:
1. The original post was not just about CPU requirements, it's just at that
time I was not aware that memory was the problem.
2. I think it's perfectly reasonable for KDE or other desktop developer
organizations to post recommended minimums for CPU and RAM on their websites
(Gnome does have this, BTW). It's not a question of the number of
combinations, just some minimums. It is CLEARLY NOTICEABLE that 32MB RAM is
does not result in acceptable performance with KDE. And I'm not talking
about using kfm for a browser or anything else. I'm talking about just
loading the desktop, no apps. I'm sure you can think of reasonable criteria
for a system's memory being acceptable, e.g. amount of swapfile use.
3. Let me emphasize that I'm not trying to slam the developers of KDE or any
other open source software. Y'all should be commended for doing the work you
do, getting no recompense only complaints. It's just that I think it's a
very small thing to ask to post a minimum recommended memory size on your
web page.
4. For the rest of you that are wondering about the memory requirements,
here's my experience. I brought the total up to 48 MB and this results in
good performance with KDE and also with Gnome.

Interesting. I have, for a long time, used
find . -type f -exec egrep 'stringIwant' {} \; -print
instead, which has always struck me as being kind of slow. I'll sure try
the xargs technique; maybe it'll do the job faster.

I'm thinking of adding a WebCam to my site. I've tried a QuickCam Express and
VC on my Win98SE machine but couldn't get anything much out of either -
crappy drivers/WebCam32 etc.
What's the best WebCam/software to get for a Linux box?
With Windoze you used to have to FTP the JPEGs to your website, but I was
thinking that as I'd only be using the camera when I was online, it would
probably be best to use my machine as a web server (just for the webcam) how
is this done?
I've setup Apache to serve pages around my LAN at home but how do you deal
with outside requests - especially as my ISP uses dynamic IP addressing.

Yes, it is slower since in this case for each hit generated by find the
grep command will be executed. So, if there are 1000 files, then you
will start grep 1000 times.

In this case the problem is in the "magic cookie".
He is not using host based security to xhost probably won't.
help ( but then it can't hurt either).
Need to check out xauth.
When root started the X server a a magig cookie file was written
it root's home directory, anyone wishing to connect to the
X server must have a copy of that file in their home directory.
At least I think that's how it works.

CNET, as a whole, seems to know nothing about Linux at all. And there are
other places besides CNET to download software. Try a couple of the major
clearinghouses for Linux software:
http://www.freshmeat.net
http://www.linuxberg.com
"xv" can take screenshots. So can Ksnapshot, KDE's screenshot utility.
You may even have one or the other installed already; "which xv" or "which
ksnapshot" to see. Read the man page for xv to find out how to use it;
"man xv". Ksnapshot has reasonable online help included.

John,
Try this... download the file to your Windows machine, then use ftp to copy
the file to your Linux machine.
Windows has a command-line ftp client: c:\windows\ftp.exe if you are
acquainted with the open and put commands. Or, snag a copy of WS_FTP or the
like.

Hello
Thank you for your answers. Actually, it seems that it's more
complicated to make it work than I expected. I used to use Outlook,
and since I have Linux, I use Kmail, which is nice, but not powerful
enough. Ok, that means that I use POP3 for incoming mail and SMTP for
outgoing mail. Mutt doesn't like this, neither do Pine (well, just a
little bit).
After a few
hours reading manpages and websites, I figured out how to retrieve my
mails from the POP3 server to my /var/spool/mail/$HOME. Nice, I can
read my mails with #mail
Still, I cannot send mails through my SMTP server. I think sendmail
is what I need, but I don't know how to configure it... Is it
simple to do and to explain ? Because it does much more than i need,
and it's quite uneasy to find the piece of information I'm looking for.
Last question. Should I use Pine or Mutt ?
Thanks a lot for your help,
Sacha

Certainly. I use Win98 to dial into my ISP, download a tar file, for example,
then I copy the file into the "shared" disk drive. I reboot to get to Linux,
copy that file into where it ought to go, then extract the tar'ed info. If
you do not have a shared area, you can mount the Win98 file system to Linux.
If these two OSs are not on the same box, use ftp or whatever to get the file
across. Good luck.

I said that my problem was exactly the same as yours, but that isn't quite

the install won't complete. I hope this helps.

The "-exec ..." version has the (possible) disadvantage that because each
grep sees only one filename argument, the name of the matching file doesn't
get printed.
I am not sure whether the GNU "find | xargs" combination makes sure that
the xarg-ed command (grep) sees more than one filename as the argument, but
to get around this (possible) problem it is conventional to use instead
$ find . -type f -print | xargs grep someString /dev/null
which means that here grep will always see multiple files (/dev/null and
the real targets) as arguments.
If you are paranoid (about filenames with spaces), you might want to read
the findutils info pages about the find "-print0" and xargs "-0" arguments.
