NO. Why should they and how can they? If it's not quoted, it might as
well be invisible. That's usenet (an unreliable medium in which you
can't rely on you being able to see something implying that other
people can see it too, and certainly can't rely on them seeing it

Welcome to the wonderful world of multiple choices. Choosing a linux
distribution is pretty much like choosing a car. If you ask ten different
people you get ten different answers.
But if you want good help you have to give us some more info. What is
your computer skills? None, M$ windows, Mac or some form of *nix?
What do you intend to use linux to do? Is it going to be a
workstation or server? Online, offline or dial-up? How much time do
you have to spare? If you (are a newbie and) want an offline workstation, one
distribution might be best (Mandrake?). If you intend to use ISDN SuSE might
be best.
Personally I have been using Red Hat (5.x, 6.x and 7.0) for the last three
years and it's been satisfactory for me (except troublesome ISDN, like most
other distributions). But I'm going to check out SuSE when they release 7.1.
So, give us some more info and we might give you an intelligent answer.
Cheers,
Kenneth

Date: Mon, 29 Jan 2001 15:40:26 +0100
Hi Jean,
I completely agree with you, even if this is possible it's not a good
idea for common applications, but my case is slightly different.
I'm thinking of using linux for an embedded application so I could just
modify the kernel to be able to access the PCI bus from anywhere, but if
possible, I would prefer not to modify the kernel. That's all.
Thanks anyway for pointing out this.
Note: By the way, I haven't measure it but a system call implies a
software interrupt (int 0x80) so I guess it would be overkilling to
issue all of these context switches every time the embedded app has to
access to the PCI bus. Maybe I'm wrong (I'm thinking of using the
fastest x86 CPU available).

I don't doubt that at all. My only point being that I used bash2 as my
default shell with 6.2 and I don't recall anything that did not work as
expected. Meaning init scripts, and other system stuff that RH installs.

Wael,
Looks like you need to set the classpath, which is a comma separated list of
absolute
path names to .jar or .zip files. For example to add the foo.jar located in
/usr/share/java
to your existing classpath you would execute
export CLASSPATH=$CLASSPATH:/usr/share/java/foo.jar
I suggest you reread the Tomcat installation documents,
and set the variable JAVA_HOME, TOMCAT_HOME, and CLASSPATH appropriately.
There is no runner.jar. If you use the startup scripts provided in your
tomcat distribution,
and have set the correct environment variables, you should not need to call
java directly
to invoke tomcat.

Kevin,
It would help if you said what distribution you are using.
strstream.h is not part of the glibc2.2 library, so you might have deleted
too much. On the RH7.0 box in front of me I have two files strstream.h
/usr/include/g++-2/strstream.h
/usr/include/g++-3/strstream.h
and are thus C++ libraries
which belong to the packages
compat-egcs-c++-6.2-1.1.2.9
libstdc++-devel-2.96-69
I suggest you look carefully at what you deleted, reinstall the packages
containing
those files using the package manager of your distribution and then upgrade or
add
other libraries using the same package manager.
Good luck
Chris

Konstantinos,
It's basic, but it works well: lynx . No mouse though.
There are Opera, and Amaya as well. I had problems with netscape,
but after some recent upgrades it works fine. Frankly, if you want all the
bells and whistles you're going to have to get used to Netscape/Mozilla.

Your `as86' is too old - get a later version. Look for either `bin86'
or `dev86'. I had the same error, and after replacing as86 with a new
version, lilo builds without difficulty.

The trick is called mmap. This means you have to write
a device driver (module) that implements the mmap system call.
Basically it works like:
1) The user uses address=mmap(FileHandle,some parameter ..) to
get an address where the mem is mapped.
2) The request is routed to your driver and used to setup
some memory mapping.
Good luck,

Stamatis,
Yes you need a System.map file in /boot for each kernel version there. The
same goes for
kernel.h . You should copy the suystem map file that was generated in your
kernel-version
build to /boot/System.map-version, likewise for kernel.h-version , where
version would be 2.2.16,
for example. You also need to configure lilo correctly; man lilo.conf .

Date: 29 Jan 2001 16:09:50 GMT
Reply-To: [EMAIL PROTECTED]
Recently, our primary DNS server went down. This shouldn't have been a
problem since we have a secondary, but in fact it was. None of the Linux
machines were able to ping anything, including their own network interface.
I would have assumed that the resolver was timing out on the first nameserver,
but since I was pinging IP addresses this shouldn't have happened, correct?
Each Linux server's /etc/resolv.conf looked like:
search mydomain
nameserver 1
nameserver 2
I then found that if I did this:
search mydomain
nameserver 2
nameserver 1
or removed /etc/resolv.conf completely then the problem went away--I could
ping. (BTW, I was using IP addresses and not symbolic names!)
This is quite scary, and I am looking for a fix. We are running RH6.2 with
Linux kernel 2.2.14. Is this a known bug, or do I need to configure something
differently?
I can supply any additional, relevant information as required. Thanks for any
help.
Regards, Dustin

I got them from debian's testing distro source, and compiled (the
