This is because (when the interrupt is set incorrectly or without one) the
kernel will poll the device rather than use interrupt lines. Polling occurs
at regular intervals - you have to wait for these intervals rather than the
serial port being able to interrupt the kernel directly - hence the delay.

Better yet, set them up correctly in the configuration file. (Ack... its
aftert pumpkin hour, sorry I cannot remember which one it is)

Yeah I agree with both the above... If linux distributions were pre configured
(with a few user input based options such as " xwindows? <y/n> ") And maybe
set up connectivity options based on a list of basic networking configurations
that should incude dialup ppp on a system that is NOT going to be up 24/7
I mean it should asumbe you need to have sendmail fetchmail and some kind of
newsfeed operational BEFORE the new user (who probably doesn't have a willing
expert to set them up handy) learns enough to start making such changes...
AND who will be more willing to risk learning what happens by making changes
if they can be sure that they already know how to get basic connectivity going
again just by running the setup program again...
Of course it would help if the docs weren't almost always written for the
precise understanding of experts with little usable info for a newbie to get
the gist of it all... (And when a man doc says the updated doc is now in
the info documents it should point you at at least one man entry to tell
you how to install info documents and certainly it should give you the
exact command line input the user would have to type to view the correct
info document IF info was installed <g>)
And I definately agree about all the gui "gestures" you need nowadays...
only as a user who lacks good mose control skills I don't find it at all funny

It will probably work but you have to realise one thing that the spec's
off the box will only make it usefull as a router or something like that
No you will not be able to use it as a workstation ..a terminal yes
a router is also possible. The MCA bus was allways supported since kernel
1.1 the only thing is that the patches required to make use off the MCA
bus may or may not work on the 1.2.36 kernel..now from I've read here the
MCA support seems to be included in the 2.2.x kernels so this fixes this
problem your 20Mb disc could be a problem but their are disro's off linux
built for small footprint opps so you may be able to recycle this box as a
router or something like that for other operations I would suggest you get
a cheap clone if money is the issue if not get a alpha or sparc ..don't
waste your money on junk PC's if you don't have to.

That is true, and they have other differences, too. The fcntl lock has the
feature that if you happen to have the same file open twice in your process
then the first close releases any locks your process held on that file,
regardless if which opened file discriptor was used to set the lock. This
is a trap you can fall in if you are not aware of this.
The BDS flock is tied to the opened fd and can be inherited to a child process.
The sysV fcntl lock is tied to the file itself and the process id and cannot
be inherited; also, it is not tied to the individual opened file descriptor.
Linux have had some troubles to sort this out in previous releases, as it
tried to emulate flock in terms of fcntl lock, but that is resolved now.
Depending on your needs you can use one, or the other, but not both on
the same file.

I think you mean they have something like a jet-direct
card (from HP). We have one color-ps HP printer with
such a card configured to use TCP as well as netware
jobs. Those cards act as a stand-alone print-server. To
print a banner you have to telnet into the jet-direct
card (or use some netware utility to do this. and then
you can configure several params like print banner,
host for log-messages and so on. See the manual for
your printer card. With our jet-direct card printing
via tcp will not work anymore when we swith off banner.
I think its a firmware bug ;-)
Hope this helps,
Sebastian

That IS not secure; But it's Linux: that means you have the choice to
configure your system as you like. Just read the man pages. From the
lilo.conf man page:
...
password=password
Protect the image by a password.
restricted
A password is only required to boot the image if
parameters are specified on the command line (e.g.
single).

So, how about your sarcasm ;-))

- Thou shalt not implement a patch in an ugly or unmaintainable manner
- Thou shalt not get a scheme implemented which uglifies or overly
complicates the kernel internals
Everything else seems to be pure `technical merit'. (And when you think
about it most of these are `technical merit' too.)
My experience when the suid scripts issue came up last, some time back,
is that there was little consensus on it and what there was leant towards
`suid scripts are not a kernel thing, leave it up to the interpreter'.
Simply that there is no consensus on it should say something.

How much communication is there between the Wine people and the DOSEMU
people? I ask because they seem to be approaching exactly the same
problem from different directions (and, admittedly, with somewhat
different emphases and goals). Is there a significant amount of code
sharing?

I had the same problem with the .rpm version. It's version 5.0.0.35, while the
regular tar.gz package is 5.0.0.45, it fixed the 100% cpu problem for me.
One thing I did notice was that if you go into the help menu, click About,
then Check for upgrade availiblity, it will tell you there is no upgrade
available, click OK, and the CPU usage drops back to normal from 100% ...
One problem with the .45 tgz package is that it is libc5, if you have a
glibc Netscape you cannot use it as a plugin ...

Yup, it's certainly libm you want. Usually you want -lm at the end of all

Umm, sounds like a problem with the program/Makefile in which
case. Perhaps you could say what the program is and what the command
line is that generates the error?

It uses the first library it finds by searching all the directories in
/etc/ld.so.conf and in /lib. If you compiled dynamically you can find
what libraries it's linked against with ldd.

What can I say? Pine sucks.
I wouldn't recommend it for newsreading at all - no threading and
ridiculously slow as you've discovered. If you want a recommendation
for a good newsreader, I'd go for tin, slrn or Gnus, in order of
increasing recommendation, and probably increasing complexity as well.

Hi,
Tim wants an encrypted file system, so I really don't understand why
everyone here seems to try to convince him NOT to use an encrypted
file system.
There ARE good reasons why one would want to encrypt files, and Unix
access permissions are no replacement for encryption. Everyone with
physical access to the machine can become `root', steal the hard disc,
etc., but it takes FAR more effort to break the encryption.
Just my EUR 0.02.

Have a look at Mandrake 5.2 a redhat 5.2 clone but with a much better

click on

KDE comes preconfigured, but much better preconfigured than on
Caldera, or
SuSE. Alternatively you could spend ages on configuring KDE on your
