check www.o2.net/~gromitkc/winmodem.html to see if your modem will even
have a chance at working in linux.
once you check that site come back here if you still have problems.

Lilo will be destroyed by Win 98.
When you install Windows, the installation overwrites on the master
boot record, where LILO stands.
The real problem would be to keep LILO...

You do realize that is software that gives any meaning to the data on the
storage device beyond just a collection of bytes or bits arranged as fixed
sized records in th case of DASD devices. It is the processor that gives
any meaning to the contents of ROMs, without interpretation the data is just
a random collection of whatever method is used to record the data. Just
like writing is just a random collection of marking for someone who can not
read it.
What do you mean by "other platforms"? It seems that you are not using the
same meaning that is attached to it by the reset of us.

yea - thanx - you're right:

I could change it:
ca:12345:ctrlaltdel:echo " ... off !!!"
but how to activate changes (without reboot of course ;-) ? Does init

Yes, I am quite aware that this is how Installshield and RPM work. That is
why I claim that all the information needed to re-factor the problem is
right there in our hands already.
Just stop for a moment and focus on the problem. Forget the execution
environment. Just picture installation and configuration as the process of
constructing and managing a large, but really rather simple data structure.
This data structure has internal references and pointers to other parts.
Some structures require particular versions of other structures in other
parts of the data structure.
If you can quit worrying for a moment about what the structures do, and just
focus on what they are and should be, it does indeed simplify the problem.
>From a data structure point of view, who really cares if one file is a font
file, one is executable, another is an initial database, a library, a
graphics file, a PDF, some html, or what ever. Or even that one file is
part of a service, another a driver, another part of the OS. It doesn't
matter what the files are, but it does matter that the files are in their
proper directories, with the proper configuration settings pointing to them.
And what cares (the OS, application, a driver, etc.) An application can be
just as dead from a missing configuration file as from a missing library
file. Or font. A graphic. whatever. And if an application is having
problems, it would be nice to know what structures I should check first.
So of course I don't want to generate install programs. Why would I? Why
even bother? The approach I am talking about simply provides structural
information about the computer system, its OS, applications, and
configuration. XML after all is in many ways a text form of a database.
Take the XML descriptions of what structures are required for each software
component. Take any set of options that are givens for this configuration.
Evaluate what should then be done to construct each software component into
this data structure that happens to be a file system. Then just render the
proper structures into storage, and keep track of what structures are being
modified, and why.
Check now and again that the structures within a computer system align with
the requirements for each software component as detailed in their XML
description. And sure, all of this information is likely to be managed
within a database.
If this is being done outside the OS (logically or even literally) then
there is really no reason the same facility can't manage different platforms
(like Solaris, Windows, Palm pilots, Linux, etc.).
Do I get some advantages? You bet. I can manage an OS even if the OS isn't
functional. If a set of applications have XML definitions that detail their
rendering, I can upgrade machines by simply rendering them as a block to the
new machine. If all the applications have renderings on two different
platforms (like Linux and Windows), I could even move a complicated
configuration from one OS to another rather simply.
I can detect if structures that should be locked down have been changed. If
this is a separate facility, I can detect hacked web sites, and fix them up,
even if the hacking got through the execution environment's security.
If I involve the various Operating Systems in this process, and all the
abstractions they define, then I complicate the process. I can't handle key
OS components the same way I handle other structures, if for no other reason
than the fact that these structures are being used. The facility itself is
exposed to anything that might happen within the execution environment.
If you were going to build a literally separate facility, doing so on Linux
makes the most sense.

Subject: keyboard mapping of Delete key
Hello,
Will someone please tell me how to make the Delete key on a Windoze
Natural keyboard behave the way it is supposed to? I expect it to remove
the current character (at the cursor position) and to move all preceding
characters back one. It works correctly in netscape, but not in xterm or
the regular non-X term. I've played around with stty and xmodmap, but to
no avail. All I know is that the delete key has keycode 107, and it
generates a "^?" character.
Thank you,
Matt

Hi
I've had the same problem, but after playing around a fair bit came up with
a solution ... or rather, tried several solutions that seems to have solved
this problem.
Please note that I am a newbie to Linux and that these fixes were all taken
from documentation on the web or from the help files. I am not an expert so
check out the online help files for kppp and www.redhat.com. There are some
other sites, but I don't have the URLs handy. If you want, I can post them
later.
Solutions (in no particular order):
/etc/security/console.apps/kppp showed that :
USER=root
PROGRAM= /usr/sbin/kppp
SESSION=false
It was suggested to set SESSION=true.
It was suggested that if there was a file /etc/kppp.allow that listed
authorized users, this would allow root and all listed users to access
pppd -- I created the file and set permissions for /etc/kppp.allow to be
readable and executable by
users.
# /etc/kppp.allow
user
user2
# add whichever users you want to access Kppp
Another suggestion was to change the permissions for pppd as follows: (this
from
redhat.com)
chown root /usr/sbin/pppd
chmod 4755 /usr/sbin/pppd
added the suid bit to pppd and made it readable and executable by all
there is the following suggestion for getting rid of the password dialog
box:
rm /usr/bin/kppp
chmod u+s /usr/sbin/kppp
ln -s /usr/sbin/kppp /usr/bin/kppp
I've tried this (but first made a copy of the original kppp file) and now I
can dial up as a user other than root.
There is also an option in the Kppp setup dialog that when selected allows
other users to use Kppp
***You might want to try this one first.
Now I seemed to have gone about this the hard way :) But it was a learning
experience and I didn't lose *all* my hair.
Try one at a time and see what happens. There may be security implications
about some of these fixes, but again, I am still learning about Linux.
Hope this helped. Good Luck

Yes, we have developed a number of great tools for describing in abstract
information, and rendering specifically to different targets. TeX, SGML,
XML, and PostScript to name a few.
Assume that I (as a developer) have two OS targets.
One is a Forth based OS that still uses block addresses and has no file
system at all. (The old Forth arguements against file systems: "File
systems are bad, cause performance problems, and real programmers don't need
them. Just give us the blocks off the disk when we ask for them!")
The other is Linux.
Can we get any more different than that? So in my application's XML, it has
a <Forth> section that lays out each <Block number="1075"> and its contents,
and continues for every block it needs. My application also has a <Linux>
section that details the directories, files, etc. that the Linux
implementation requires.
If it is so easy to see how I can describe these two installations, why is
it so hard to believe we can cover Linux, Windows, Solaris, etc.?
This thread isn't about auto-magically constructing valid represenations of
applications for any OS. This is about being able to describe a valid
representation on any OS.
Given a technology like XML that can be used to describe structured data
(and variations of that structured data), use that to describe the set of
software components for a computer system. Then render those components as
described, by managing in context their needs as defined as how they should
be expressed in storage.

So far so good.
I can log into ftp sites but I can not get directory information from

The error is: Opening ASCII no print mode for data connection for ls -l.
