Not this time: it's perfectly valid to declare variables at the start of
a block. The following program compiles fine with cc -Wall:
#include <stdio.h>
int main (int argc, char **argv)
{
printf ("Hi\n");
{
FILE *f = fopen ("test.c", "rb");
FILE *f2 = fopen ("test.c", "rb");
char buffer [80];
buffer[79]=0;
fgets (buffer, 79, f);
printf ("%s", buffer);
fgets (buffer, 79, f2);
printf ("%s", buffer);
}
return 0;
}
However, the declaration of buffer is below some "real" code, and that
is, I believe, invalid.
Personally, I don't like calling *any* functions while I'm still
declaring variables (in the way that I have above), but gcc at least
doesn't complain...

Hi,
I'm doing batch PPP connections to a Linux server in order to perform
file transfers.
Sometime, the upload fails returning the message "File Table Overflow
..." ! But the same upload (same file, same server, same location)
performed few seconds after is successfull !
Does anybody have an idea of the problem, and perhaps know a solution ?
Please answer at [EMAIL PROTECTED]

No, I think you miss my point.
The location of the data is unimportant, you just search for the data
using terms that are meaningfull to you (could be in your own language
- etc). Your computer finds the data for you - either locally, or
remotely. The data may be local, or remote in an archive of data you
have created (e.g. on your home server, or in your online internet
space) or the data may be global i.e. shared by all online users (e.g.
dictionary or thesaurus).
Your computer would decide whether to cache the data locally in case
of a repeat request. The data itself would be tagged to show whether
it was unchanging, e.g. a historical fact doesn't change (interest
rate at particular time and date) or volatile (e.g. current stock
price). Your computer would then take appropriate action to maintain
the avlidity of that data. For instance an historical stock price
would be cached locally until it aged so much (by being unused) that
keeping it locally was less important than other data. A current stock
price would be kept refreshed whilst being accessed, and would be
refreshed on subsequent accesses.
At present the volatility of data is handled by applications. Take
stock prices as an example, a program is explicitly written to keep
requesting the data periodically. But this is conceptually arse about
face so to speak. The volatility of the data is an aspect of the data
and should be supported by the data access mechanism - the OS. This in
the same way that ownership of data is supported by the OS (rather
poorly at present). Similarly the 'cost' or value of data should be
supported by the OS. I.e. when you access a datum - the cost of doing
so should be paid for in 'net credits' or whatever transparently by
the OS. You the consumer simply decide what preferences you require on
access to data. You may decide to pay premium rates for immediate
response or less for somewhat delayed data (again stock prices are a
classic example - or news). You might decide who you 'buy' data from,
or may let your computer decide given a number of parameters (e.g.
maximum cost you'll pay, speed of access, time of access (overnight
downloads)).

Hi, I currently have a windows 98 machine, and a pent 90 with DOS. I was
wondering if it was possible to install linux on the DOS computer through a
network. Does the network have to be set up first? The hub and all the other
stuff are set up, but stuff like samba are not in place since linux isnt
installed yet.
My question : How do I install linux on a pentium 90 computer which has no

Hi,
I have recently purchased some Compaq 3000 & 6500 Servers and am in the process of
putting
Debian Linux on each of them.
The base system installs fine and all seems to be working, until I try and install the
ethernet
card. The Compaq comes with a Tlan dual 10/100 ethernet adapter which is fine and and
half
recent kernel has a module for it, but my problem is that it tries to put it on IRQ 15
where the
SCSI card is already sitting.
Does anyone know why this is doing this and how to fix it?
Also is there any way to control the LCD screen on the front of the Server and/or the
server
utilities such as pre empting a hard disk failure and those kind of things.
Thanks,
Aaron

I guess this is burried deep in a man page but I can't find it.
How do I get an xterm on my box to display a remote host name when I connect via
telnet.
If I switch to tcsh on the remote host (sun box) my linux X-term displays the
remote path but no host (if I open a local Xterm then I get the my host & path
displayed).

If you can get the printer to work with the RH printfilters and thus throw

Hello to everybody.
I'm trying to print from a redhat 6.0 linux box on some printers having
Jetadmin engines.
Right, I was installing the WebJetAdmin for linux from HP, AND i make
the arrangements suggested by the instructions (security & so on)
It seems run (I can search the net to locate printers ...), but when I try
to
install a printer using the linux as a print server, i select the server
(using
its web interface), also the printer's IP, the type of printer and when i
push
the button for "Create Queue" i get the funny message:
=====
Print Path Creation Failure
Description: Error: Queue creation failed: PPS_TIMEOUT
Return to previous page and try again

if i take the image of processes i found:

It seems that the hppspps is not a happy process, but I have no extra info
about the failure
(no logs in message, etc.)
Could you help me please,
I'll be very recognized.
Thanx in advance,

The problem with gets is that it doesn't let you bound how much data
you're prepared to accept. When you hear about the latest "buffer overrun
security bug" that's usually because someone has used gets.
Use fgets instead, with stdin.

More likely (in this case) I suspect is that he's running out of file
descriptors. If you're using a 2.2 kernel, try looking at
/proc/sys/fs/file-max and the documentation for it (in
/usr/src/linux/Documentation/sysctl).
Turning logging off for some of the hosts, or logging to a single file
and splitting it later, may help.

Yes, you can set up a RedHat system (and probably many others too) using
on the network. You'll need to create a couple of boot disks in the
normal way (using a machine which *does* have a CD-Rom) and mount the CD
for NFS use - then install via NFS. It *may* even be possible to install
over the Internet from redhat.com, but I wouldn't advise it...

I've looked in the Settings Menu under Screensavers where you can select
