Only on an unupdated Red Hat 6.2 system. If you have updated your Red
Hat 6.2 system properly you should have rpm 4.0.2 (see
http://www.redhat.com/support/errata/rh62-errata-general.html and more
specifically http://www.redhat.com/support/errata/RHEA-2001-016.html).

It is simple, if you have updated your system properly. First of all
there was a rpm 3.0.5 update to Red Hat 6.2 (see
http://www.redhat.com/support/errata/RHEA-2000-051.html) in August last
year. All versions of rpm, starting with rpm 3.0.5, can handle rpm v4
packages.
Later, this march, there was an update to rpm v4 for Red Hat 6.2. Since
everyone who had updated their system properly had a Red Hat 6.2 with a
version of rpm that could handle rpm v4 packages (rpm 3.0.5), I believe
that they probably didn't feel the need to distribute the update in rpm
v3 packages.
So the correct procedure is probably to do these updates in
chronological order: update to rpm 3.0.5, and then to rpm 4.0.2. Do a
"rpm --rebuilddb" after you have updated to rpm 4.0.2.
Also, subscribe to the Red Hat watch list (send a mail with "subscribe"
in the subject to [EMAIL PROTECTED]). Then you know
what updates are available the moment they are released.

I agree. Also, updating the system properly is the key to avoid attacks,
so making it a habit to apply security updates released by your
distribution vendor is a good habit.

To be honest, I don't understand your question.
Yes, I know that people have reported that Red Hat Linux 7.1 finds CDRW
devices and configures them out of the box, and yes, Red Hat 7.1
includes cd-writing software (most notably cdrecord but probably also
some frontends), but no, I don't understand why that has something to do
with the way you boot into linux.

Subject: gpr Problem Under RH 7.0
I installed grp and all the required rpms from HP's sourceforge site.
I'm running RH 7.0. There were two error messages when installing saying
the script failed for gpr and libppd. (Everything else seemed to install
and there were no other error or warning messages. As far as I can tell,
gpr and libppd actually did install.) I tried to reinstall these
components but gnorpm said they were already installed. I forced them to
be re-installed just in case.
The new lpr works with the ppd file for the HP 8000 printer when I type
in the options. I know what the options should be from running gpr with
the -n option. gpr runs and I set it up to go to the correct ppd file. I
also used the new printtools that sees the new ppd files. As long as
I use lpr it all works. When I try to print using gpr, I can see stuff
going out the eth0 connection (using usernet) but it NEVER prints on the
8000. (The HP 8000 is connected directly to the network. I was able to
use the "autodetect" feature of the new printtool.)
When I've used the -n option on gpr, if I just copy ALL the generated
command, again nothing prints. If I just use the few options I actually
need (papersize, copies, which tray), then lpr works fine. But the lpr
command constructed and displayed by gpr just does not work.
Does anyone have any idea what is going wrong? I'm estatic that I can
use the ppd information now to control the printer, but I would love to
be able to use the graphical gpr program.
Thanks.

You might want to have a look at the quota package, which I believe
can do this sort of thing. Also `du -s /home/*' (assuming the home
directories are in /home, and not somewhere beneath it) might help.
Have a look at the man page to see if it'll do the various other
things you want.

Subject: RH 7.1 iptables with insmod errors
Date: Thu, 10 May 2001 12:27:50 -0400
Hello,
I have an iptables problem. I just installed Redhat 7.1 with kernel 2.4.2-2
that supposedly has iptables kernel support. I have a modem on the external
and NIC on internal. The modem works fine when I run wvdial or similar. I
simply want to run IP masquerading for my other machines and share the
connection. First I went to http://linux-firewall-tools.com/linux/firewall
and built my script using the iptables option. After I was greeted with an
awful scrolling screen of errors, I was displeased. Below is the output
from iptables -F to give a TASTE of the problem:
[root@firewall /root]# iptables -F
/lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: init_module:
Device or resource busy Hint: insmod errors can be caused by incorrect
module parameters, including invalid IO or IRQ parameters
/lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: insmod
/lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o failed
/lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/ip_tables.o: insmod ip_tables
failed
iptables v1.2.1a: can't initialize iptables table `filter': iptables who?
(do you need to insmod?)
Perhaps iptables or your kernel needs to be upgraded.
And when I manually try the insmod ip_tables:
(From insmod /lib/modules/2.4.2-2/kernel/net/ipv4/netfilter/)
insmod ip_tables.o: init_module: Device or resource busy Hint: insmod errors
can be caused by incorrect module parameters, including invalid IO or IRQ
parameters
IRQ and IO problems? The modem works fine when I dial out, so I don't think
it's that. I must be missing something. All I want to do is masquerade and
firewall my home LAN. Any ideas? Thanks.

Below is the a snippet from /proc/pci, if that's of any help.

One of the machines I set up doesn't do web, but it does dns, mail,
ssh, and routing with 32 megs, and has enough RAM left over to have about
12 megs of disk cache - and that's with 'seti@home' eating up 40% of the
memory. To add IRC and Apache, add another 5-20 megs of RAM, depending
on how crazy you go with the number of forked-off HTTPD servers. That's
using qmail and djbdns, not (shudder) sendmail and BIND. If you compile
with diet-libc, you'd save even more RAM, but that's starting to get a
little pedantic. : )

Wow. Either you have super-human hearing, or you're buying the wrong
disks, but hey, either way, the customer's always right. : )
Realistically, here are some suggestions. If you simply want the
machine to boot from a CD-ROM, copy important stuff to a RAM disk, and run
from there, you could certainly make it work with 64 megs, but as cheap as
RAM is, 128 would be good. If you want to also include development tools
in the RAM disk image, like a compiler, kernel headers, etc., then 128 or
256 would be plenty. If you really want to, go ahead and use 512 megs -
but unless you're planning on putting on nearly a full distribution, it's
almost certainly overkill. : )

Hi
I've just installed RH 7.1 and experienced a very strange problem. After I

then after about 5 seconds, it display one more dot. Only when it has about
15 dot, the system continue to boot. I didn't experience this problem before
with RH 7.0 or Mandrake 8.0. Does anyone have any idea, please help me.
Anyway I'm installing RH on the second disk ( slave on primary ) if it
matters.
One more problem. After log in, I think the hd runs really really slow as
well. I tried to optimize it by hdparm as advised but it didn't improve
anything, any all parameters go back to the original value after each
reboot. I'm really a newbie so I dont know what to do know.

Rene,
The load average represents the average number of processes=20
that are waiting in the run queue (i.e., waiting for the CPU).=20
The averages are calculated for 1, 5, and 15 minutes (3 numbers).
The higher the numbers, the more loaded your system is.

Is there a reason why sprintf() wouldn't satisfy you?
Is there a reason why you couldn't write an itoa() implementation that suits
your needs (I could, and have posted it and variations to the newsgroups in
response to these sort of threads every once and a while).
itoa() isn't an ANSI C function, and (IIRC) isn't even a posix/sus function.
It's an _optional_ function that is supported in some environments (aparrently
MSDOS / DJGPP supports it).

In case you missed it, here's an itoa() implementation that I posted a couple of
weeks ago...
static char *_itoa(unsigned i, char *a, unsigned r)

A very quick search of a very recent thread would have shown you that
you need to be sure to 'rmmod' the ipchains module before trying to
insmod anything iptables related. RH7.1 automatically configures an
ipchains based firewall.
