Your only realistic possibility is to move /home data somewhere else.
This is the reason why you should _always_ have /home as a separate
partition from "/" (root).
Alternatively, I'd think the obvious alternative to be to copy /home
off to your backup medium.
You _do_ take backups, don't you? Linux may eliminate most of those
annoying "blue screens of death," but has no way of resolving the "Oops,
the disk drive went bad" problem. The only resolution to _that_ is to
have some sort of backup regimen...

Consider...
c) "Modern" x86 processors aren't as readily distinguished from RISC
processors as used to be the case.
d) "Pure" RISC systems were only popular in academia, and that only
for a fairly short period of time.
The _real_ point to the RISC/CISC division was more to step back
rethink the issue of how to optimize CPU behaviour than it was to
create the One True Architecture; since the early days, "CISCy"
processors have taken design principles from the learning from RISC,
and vice-versa.
e) x86 chipsets aren't terribly flexible, and suck _reasonably_
badly.
But the chipsets for RISC processors tend to be _lots_ more expensive
for anything involving small production runs because there are just
_SO MANY IA-32 motherboards_ out there.
As for cost, a StrongARM CPU may cost $25, but I defy you to try to
find a motherboard priced less than $500. Ditto for MIPS and PPC.
f) A lot of the benefit of RISC supposedly comes from having
simple-but-fast instructions. Unfortunately, this means you're stuck
with consuming more memory to store more verbose programs. And thus
consume more memory bandwidth.
It may still be a win to "do RISC," but the memory bandwidth issue
_does_ throw away some of the cycles that got saved.
g) And note the .signature; Intel may not be able to make a
"racehorse" out of the 8008. It's still a "pig." But given billions
to spend on fabrication plants and design engineers, they can make an
_awfully_ fast pig out of it.

Depends on the particular CD-R(W) in question. Some can manage this,
some can't. Anyway, it seems as though most CD-R(W)s can retract the
tray automatically when the drive is accessed. Try ejecting the tray,
then issuing a "mount" command--for most drives, the tray will slide in.
If you do end up having to eject, a simple mount/umount will slide the
tray back in. It's really easy to script, and would take about 10
seconds....

Not a really brilliant nor helpful comment, Rinaldi.
I happen to agree with Gabe. Netscape does 'suck'. The most stable
version I've
found is 4.73, and it hangs on java scripts that display certain
graphic images,
like the radar images at weatherchannel.com. And, it will simply go
away at times,
without warning, if it doesn't just lock up.
What to replace it with? Well, since I use KDE, I found that kfm works
nicely on
most sites that don't fire java applets to do the major work of the
site. It is
very fast, too! I tried M17 and AOL Netscape 6.0 but they are bloated
pigs that
crash too often and aren't finish yet, after oooo so loooong.
So, I use NS 4.73 to visit news sites where I want to see videos, or to
visit sites that have important java apps displaying the good stuff, but
kfm for
just browsing and reading and responding at, for example, LinuxToday or
Slashdot.
When KDE 2.0 comes out it will include Konquorer and I will switch to
that.
Work on your bedside manner, Rinaldi. Arrogance makes a poor
instructor. Do you
remember when you first started out? What did you think of all those
air heads
who sent your 'rtfm' responses to your questions? Or responses like
yours.

I'd say you haven't gained anything. In fact I wouldn't even call that
marked-up, since all you have done is wrap a couple of meaningless tags
around it. Possibly if the ID attribute means something you have
gained the ability to parse the ID tag using a standard XML parser,
which isn't much.
XML is no use to anyone if it isn't actually used for markup. There
isn't much point having a document consisting of one element and a
CDATA section.

Correct me if I am wrong, but I believe that XWindows should not be
installed on a "server" as it would pose a security risk.
Perhaps you should choose another installation option.

Reply-To: [EMAIL PROTECTED]
Is there a way to have the permissions to any file created in a given
directory adopt the group permissions assigned to the directory itself
rather than the primary group of the individual creating the file (when
individuals belong to multiple groups)?
Sometimes, group permissions are assigned on the basis of an
individual's primary group, rather than the group specifically
associated with the directory.

I disagree. XML might be an new form of an old idea, but it's been
done well and this time it has a lot of support. There are XML tools
out there - a lot of them - available on a lot of platforms and in a
lot of languages.
SGML might well do the same job - but is there a standard API for
parsing SGML that has the support of major software companies? Is it
available as an OLE object a Java implementation, and C++ library?

Maybe I don't understand, but just for the record, there is a difference
between 'su' and 'su -'. The first will make you root, but will NOT
change your environment, which seems to be your problem. The second forces
the root environment to be set; i.e. you will be put in the /root directory
and have all the root pathing set. This works regardless of the telnet
product or OS being used to connect from. I regularly telnet in from my
children's Windows machines to correct/modify things when they're having
problems.
As an aside to all this, my main box (at home) is video & keyboard less as
is my database box. All control/functions/applications are run from them
through a third small box which runs three (3) instances of Xserver ( :0,:1,:2)
each displaying the kde desktop for a particular machine; i.e. :0 is local,
:1 is the main server and :2 is the database server. Since the network is
a switched 100Mb (full duplex), latency seems to be almost nonexistant. All
logging from the database server (and the videoless/keyboardless LRP router/
firewall) are logged to the main server which displays the important log info.
on the VT550 serial terminal on ttyS1. Note also that when the mainserver
boots (rarely necessary), I do not get the bios messages but do get everything
starting with the lilo prompt.
Also, if you need to see the bios messages for a headless machine (say in a
server farm) there is a PCI card that will put them to a serial terminal and
allow console like control.

Subject: Port forwarding on RedHat 6.2 ?????
Date: Thu, 31 Aug 2000 00:57:21 GMT
Hi there:
I am having a little problem with my port forwarding and I was wondering
if somebody has a solution.
I am running RedHat 6.2 (with kernal 2.2.14-5.0 ) on an Intel box as a
firewall. The box has two Ethernet cards and is connect trough PPPoE on
an ADSL line. Everything is working fine, my internal network can access
the outside ......... however, I am not able to forward ports to my
server on the internal private LAN.
Here the setup:
- Internal HTTP server 10.0.0.10
- Ethnernet card to the internal LAN 10.0.0.20
- Ethernet card to the internet --> PPPoE on ADSL line
Has anybody a concrete suggestion on how to forward port 80 to my
internal server 10.0.0.10 ????????????
