I'd rather upgrade to 2.2.19, which fixes some security bugs.
For 2.4.5 there's already an ac patch and from the ChangeLog 2.4.5
is, again, not really unproblematic yet.

You'd have to upgrade not just the kernel for 2.4.5, beware.

Since you're in the process upgrading pretty much else at the moment
I'd even more not upgrade to a new kernel release. You've your work
cut out already and in the meantime could let 2.4.x ripen a bit more.
I'm a bit conservative at times, yes,

I used to find that KDE apps tried to be *too* intelligent: doing a
save-as for a web page in Konqueror would default to trying to save to
the host at which the web page is hosted rather than my (local) hard
drive. Perhaps KNode is trying the same?
When you click save, does it give you a file dialog? If so, check the
location to which it's trying to save. Is it defaulting to your news
server?

Uh, do you really think it would be a good idea to let any user close
down any other user's ( especially root's) programs? Can you imagine the
problems?
Anyway, go to
theory.physics.ubc.ca/ppp-linux.html where there is a link to a program
to kill pppd by any user. This means that if you are connected any user
can disconnect you. If that is OK, use that program.

Eventhough I use startx it only works when i write it ("xterm -e /bin/bash &")
in .xinitrc. What should I write if I don't want an xterm but a terminal like
the one I can get using the quick launch toolbar (default in Mandrake 8.0)?

I've set up Red Hat 7.1, and the operating system will not recognize
my serial, external, USRobotics Courier v.everything modem. I've
tried using the internet configuration tool in Gnome. And it won't
find the modem using "auto." And I can't find the modem manually.
Using the command line as root, and trying to ls /dev/modem, I get a
message that reads "No such file or directory." I've tried installing
RH 7.1 as a workstation and as a server, but no luck with this problem
either way. Did the setup program fail to install something that is
needed? And if so, what do I do about it? --JWR

I'll assume, perhaps incorrectly, that this is a serious post, and not a
troll...
Linux is a very powerful and sophisticated system that, though it becomes
more approachable with each new distro and release, still requires fair
amounts of technical expertise and experience to install and exploit. It is
certainly not for everyone, and it sounds like it may not be for you. You
don't _have_ to use Linux. You don't have to prove anything.
Linux is great. I like it and use it for a number of different things. But
Windows (especially 2000 Pro) is also a very capable system that I like and
use. Many folks will never know anything except Windows, and stiil get
everything they need out of their computing experience.
If Windows satisfies your needs, and you have no desire to grow technically,
to learn, and to get past the "simple Type a:\install" mindset then probably
you should not be considering Linux.

Well, I have flashed BIOSes many times without any problems. As you
properly said, you can always flash your BIOS back to the old version if
problems occur. HOWEVER, if something really bad happens while you are
flashing (power failure, system crash), then your BIOS will be rendered
unusable and the actual chip on your board will have to be replaced (or
properly re-flashed by other means, as you no longer will be able to start
your system and access any FLASh utility). Luckily, this has never happened
to me, and I think that if you're a little careful, it should be possible
to flash your BIOS without any trouble.

I realized that I have gid 501 at /etc/group for 2 users. This is probably
done by accident. Is there any tool I can use to manipulate /etc/group and
/etc/passwd?? Or which program do I have to call after manipulating these

I have Mandrake 8.0. (Mandrake's tool userdrake cannot manipulate gids and

Generaly speaking, all u nee for mail server is static IP ( I assume uve got
it from ur provider, prolly a range of IP`s for ur company) and a i.e. Linux
server.
About distro, well, ppl will tell u lots diff versions. For me, Slackware is
most reliable and secure.
Next, is to configure the box. First, u have to enable sendmail and pop3d. I
suggest popa3d from GNU.
Next step is securitty issue, to set relay for ur domain ONLY!!! (Otherwise,
spammers will nail u) Search for /etc/sendmail/relay-domains.
After that, I also suggest shutting down all daemons which go by defau;t and
u dont need them (apache, telnet etc etc. I say telnet, bc if u need remote
access, use SSH)
After that, u should prolly set ipchains (iptables) based firewall to
protect ur box from outside access for sure.
For HOWTOW-s, and more info, try www.linuxdoc.org
Well...
That would be the simplest answer. :-)))

Have you tried ls /dev/ttyS1 (com 2), ls /dev/ttyS2 (com 3) , etc. ?
IIRC, /dev/modem is
simply a link to /dev/ttyS whatever.

Of all serious crimes under the law, smuggling...
least violates the consciences of men. It is a crime
against law and against government, but not against
morality. The smuggler robs no man. He buys goods
honestly in one market and sells them honestly in
another. His offense is against an arbitrary regulation
of government.... he simply fails to pay its demands.
Many men otherwise honest are unable to see any moral

/dev/modem should be a symbolic link to /dev/ttyS0 (if the modem is
plugged into the first serial port) or /dev/ttyS1 (if the modem is
plugged into the second serial port). If /dev/modem doesn't exist,
become root and create it with the command
ln -s /dev/ttyS0 /dev/modem
and things should work better.
You can also point the modem configuration tool (gnome-ppp? kppp?) at
/dev/ttyS0 and things should work. HTH,
